Context of Vignettes and Ethical Sensitivity in Decision-Making Among Undergraduate Business Studies Learners at University of Nairobi, Kenya

Vignettes have been applied to train professionals in various fields, which has contributed to significant improvements in learning outcomes, ethical sensitivity and learners’ ethical decision-making. At the University of Nairobi’s Department of Educational Communication and Technology, most instructors have been slow to embrace experiential learning and inconsistent in applying vignettes to deliver business ethics lessons that emphasise ethical sensitivity in decision-making, with far reaching effects on the quality of graduates. This study responded to the information gap about the relationship between the use of vignettes and learners’ ethical sensitivity in decision-making at the University of Nairobi. Cross-sectional survey design guided the research process, and primary data were sourced in 2018 from 116 learners. Both quantitative and qualitative analysis techniques were applied. Key results show that learners who agreed strongly that the context of vignettes influences ethical sensitivity in decision-making were about 3.9 times as likely to make ethically sensitive decisions as colleagues who disagreed strongly. Those who agreed that the context of vignettes influences ethical sensitivity in decision-making had about 2.3 times the odds of making ethically sensitive decisions as colleagues who indicted strong disagreement. This means that the more the learners appreciated that the context of vignettes influences ethical sensitivity in decision-making, the higher the chances of them making ethically sensitive decisions, and vice-versa. This brings to the fore the need for instructors to consistently apply the context of vignettes to deliver business ethics lessons to improve learners’ ethical sensitivity and propensity to make ethical decisions. The study recommends that for practice, vignettes business contexts should be integrated in teacher training business studies ethics lessons.

are only passively involved in the learning process as recipients of information, a fact that limits creativity and impairs the development of essential professional skills (Petrina, 2004).
Instructional methods are pre-determined procedures through which instructors and learners interact to facilitate the learning process (Sarfo, 2007;Gray, Griffin & Nasta, 2005;Petrina, 2004) for improved decision-making. Effectiveness of an instructional method is judged by the extent to which it captures learners' interests, optimises learning outcomes, and facilitates cognitive processing, storing and retrieval of information. All these draw extensively on sensitivity in ethical decision-making. Instructional methods are further evaluated by the extent to which each promotes learners' active participation in the learning process and limits dependency on instructors (Petrina, 2004;Hativa, 2000) to encourage reflection, dialogue and peer feedback for greater ethical sensitivity in decision-making.
Extant literature reveals a wide genre of instructional methods, which can be grouped under five models, including direct instruction, which is transmissive or classical instruction; indirect instruction, also known as transactive instruction; independent study; interactive instruction; as well as experiential or work-based learning (Petrina, 2004), all of which require sensitivity in ethical decision-making. Experiential learning is a unique model of instructional methods for developing the capacity of learners based on real life experiences, which are deeper and more complex than classical instructional methods such as, lectures. Harland (2014) argued that while the classical model transmits abstract information, which most learners struggle to put into perspective, experiential learning deploys practical experiences which learners can easily connect with to achieve mastery in ethical sensitivity and decision-making, and may improve choice of approach for effective and efficient management of professional development. In line with this thought, Petrina (2004) elaborates that experiential learning is about developing decision-making skills by enabling learners to reflect, discuss, share experiences, and apply such skills to tackle similar challenges requiring ethical sensitivity in decision-making. This suggests that experiential learning is a learner-centered model, under which learners are granted autonomy to actively drive the learning process by critically analysing content, engaging with peers and instructors about the content, and building consensus (Harland, 2014). Within the ambit of the business ethics course unit, experiential learning enables learners to understand and develop necessary skills for making sensitive ethical decisions from real life experiences for enhanced learner achievement in the teaching-learning process. The experiential learning model deploys a wide spectrum of learning resources, including vignettes, which Kidwell and Valentine (2009), as well as Mazanec (2005) in their earlier studies, hold in high regard as influencers of learners' critical thinking and perceptions about real life experiences. More distinctively, Kidwell and Valentine (2009) elaborate that vignettes create a vital linkage between the learning process and learners' previous experiences in various facets of life, including work; while Mazanec (2005) observes that the deployment of vignettes in teaching sensitivity in business ethics is crucial for influencing learners' sensitivity in decision-making. Pan and Sparks (2011) view ethical sensitivity as an essential antecedent to ethical decision-making promoting effectiveness and efficiency in the use of instructional resources, methods and activities necessary for teaching-learning processes.
A review of pertinent literature reveals that vignettes have been applied to train professionals in various fields, including nursing, psychology and marketing (Allibaih & Khan, 2015;Emanuel & Cross, 2012). The cited studies have linked vignettes to significant improvements in learning outcomes, ethical sensitivity and learners' ability to make ethical decisions in work contexts. Similarly, Effelsberg, Solga and Gurt (2014) hold the view that the use of vignettes influences learners' ability to make ethical decisions, especially by enabling them to systematically and actively discuss ethical issues. Oluoch, Odundo, Mwangi and Oyier (2018), reiterate the importance of vignettes in learning, perceiving them as elemental instructional resources for developing learners' ethical sensitivity, in addition to preparing them for decision-making in professional contexts.
Despite the cited advantages about the use of vignettes and tendencies of ethical sensitivity in decision-making by learners, anecdotal information suggests that most instructors at the Department are slow to embrace experiential learning, and are inconsistent in applying vignettes to deliver business ethics lessons. Oluoch et al. (2018) have attributed the challenge to various factors, including instructors' insufficient use of experiential learning approaches and limited appreciation of how the use of vignettes in business ethics lessons influences learners' ethical sensitivity in decision-making proclivities. There is no doubt that these challenges have undermined the effectiveness of business ethics course in preparing learners to function effectively in their work locales (Oluoch, Odundo, & Mwangi, 2019).
Even though vignettes have been used to train professionals in various fields, in education, there is remarkable paucity of empirical literature focusing on the application of vignettes and the influence on learners' ethical sensitivity in decision-making (Oluoch et al., 2018;2019). More specifically, no study has examined how the use of vignettes to deliver the business ethics course unit influenced ethical sensitivity in decision-making among undergraduate learners at the Department. The resultant dearth of information has contributed to delay in pedagogical reforms at the institution. This study responded to the information gap by assessing the influence of vignettes on ethical sensitivity in decision-making among business education undergraduate learners at the UoN.
The study covered five aspects of vignettes, namely the context, content, types, construction and utilization; however, this article delves into the relationship between the context of vignettes and ethical sensitivity in decision-making among the said learners. The study sought to generate information that would synergize pedagogical reforms at the Department, in addition to motivating further relevant academic research in Kenya and elsewhere.

Literature Review
Developing teachers, institutional managers and leaders with a high level of ethical sensitivity in any sector starts the provision of the right professional training, using correct instructional methods (Pont, Nuschew, & Moorman, 2008). There is a need to prepare leaders who are both knowledgeable and practically effective. Theoretical or academic work is complemented to a greater or lesser degree by experiential learning, problem-based approaches as well as experience. Vignettes are instructional resources that pre-expose learners to real life experiences in order to develop their ethical decision-making skills (Kidwell & Valentine, 2009;Davis, DeZoort, & Kopp, 2006). In the ambit of business ethics course unit, vignettes subject learners to practical ethical dilemmas that reflect challenges experienced in teaching and management of educational institutions. As noted by Guzak and Hargrove (2011), an effective instructional method should enable learners to develop positive values that promote ethical sensitivity in decision-making in all positions of responsibility. Literature on business education units reveals (Woods, 2014) five organizational contexts from where vignettes can be developed to support the training of future duty holders, including structural, operational, financial, human resource and marketing.
The structural context consists of Business course units that make decisions for safeguarding or furthering organizational interests, especially ethically sensitive teaching-learning processes. Each structure influences ethical decision-making differently for improved learner achievement. A few empirical studies have examined the relationship between the use of structural context vignettes and learners'/employees' ethical decision-making. For example, Oluoch et al. (2019) reported that 87.3% of the learners contacted affirmed that structural context vignettes influenced their ethical decision-making tendencies; while Van Summeren (2018) established that employees' ethical decision-making was influenced by sensitization using structural context vignettes, which should be embraced at the professional training level. Van Summeren (2018) explained that the use of such vignettes enabled employees to understand organizational ethical policies guiding various aspects, including financial, human resource and marketing management practices. Similarly, structural vignettes enable teacher trainees to bridge the gap between theory and practice for transfer of learning about policies and how they apply in practice in finance, marketing or human resources management.
In an earlier study, Butterfield, Treviño and Weaver (2000) observed that employees' propensity to make ethical decisions is a function of how often employees are informed about organizational ethical policies governing structural functions. On his part, Detert, Treviño and Sweitzer (2008) argued that the use of vignettes to disseminate information on organizational structural functions is essential for enhancing learners' ethical sensitivity in decision-making skills. The relationship between the use of structural context vignettes and ethical sensitivity in decision-making among learners also features in the study by McNamara, Smith and Murphy-Hill (2018), which reported lack of a significant difference between learners instructed using structural context such as code of ethics and control group, in terms of conformance to a standard code for making sensitive ethical decisions.
The operational context consists of functions that contribute to the achievement of organizational purpose, including planning, organizing, directing and controlling activities related to core mandate and ethically sensitive decisions which arise. As all operational functions involve ethically sensitive decision-making, Effelsberg et al. (2014) observed that vignettes inculcate positive attitudes and values that are essential for ethical decision-making within the operational context of the individual. Despite this, few studies have assessed the relationship between the use of operational context vignettes in training learners' ethical sensitivity in decision-making. Those that have, only report some basic descriptive findings. For example, Oluoch et al. (2019) found that 89.7% of the learners affirmed that the use of operational context vignettes influenced ethical sensitivity in decision-making predispositions. 2019) requiring prudent decision-making, which should be ethically sensitive. Vignettes are valuable instructional resources for developing learners into teachers of finance and financial managers with a sense of ethical responsibility. The use of vignettes is effective for sensitising learners about ethical aspects of institutional financial management. This implicitly suggests that the use of financial context vignettes and learners' ethical sensitivity in decision-making might be causally connected (Racelis, 2015) such that, trainees who are unable to perceive ethical issues where they exist may recommend inappropriate actions and vice-versa.
Human resource management is a set of skills that entails making ethically sensitive decisions to optimise workers' productivity, which determines learning achievement during the teaching-learning process. Vignettes have been found to be important instructional resources for developing the capacity of learners to become more effective in making ethical decisions concerning human resource issues. For example, Marques and Azevedo-Pereira (2009) implicitly suggest that training learners using human resource context vignettes is essential for improving ethical sensitivity in decision-making practices. Similarly, in Oluoch et al. (2019), 87.2% of the learners affirmed that the use of human resource context vignettes led to the tendency to make ethically sensitive decisions. The findings emphasised that ethical sensitivity in decision-making would enhance teacher trainee practice of teaching and learning for better achievement.
Lastly, training of business ethics involves exposing learners to issues in marketing context using appropriate vignettes so as to improve ethical sensitivity in decision-making skills for improved class management and learning. As noted by Barczyk and Duncan (2012), training institutions have a moral obligation to design instructional methods and resources that enhance learners' ethical sensitivity and ethical decision-making skills. Guzak and Hargrove (2011) describe vignettes as essential instructional methods and resources for developing learners' sensitivity in decision-making on various aspects of marketing for enhanced performance and instilling higher moral values. More explicitly, Oluoch et al. (2019) indicated that 87.2% of the learners affirmed that marketing context vignettes influenced ethical sensitivity in decision-making practices concerning various aspects of marketing. This, in turn, facilitates mastery of concepts and values clarification for efficient teaching-learning processes.
The study is anchored on the Experiential Learning Theory (ELT) to explain the process of human learning through experience (Kolb & Kolb, 2017;McLeod, 2017). Learning, in this context, is explained as a process of creating new knowledge by transforming experience from problems to decisions. The Theory consists of six propositions on human learning, viz. learning is a process and not an outcome; learning is a continuous process grounded on experience; learning requires resolution of conflicts between dialectically opposed modes of adaptation to the world; learning is a holistic process of adaptation; learning results from synergistic transactions between the learner and the environment; and learning is the process of creating knowledge (Manolis, Burns, Assudani, & Chinta, 2012). To address the uniqueness of human learning in the teaching-learning of Business Ethics course unit, sensitivity in decision-making is critical in capturing the imagination of the learner for better outcomes.
The Theory encapsulates two interdependent concepts, namely, a four-stage cycle of learning and learning styles, which jointly enhance effectiveness in explaining experiential learning anchored on the ability of the teacher to choose sensitive and learner-appropriate methods and resources for better attainment. The four-stage learning cycle postulates that experiential learning occurs when learners progress through a cycle of four stages, including a concrete experience (CE) or encounter with a new situation; and reflective observation (RO) of the new situation, focusing on its consistency with past experiences. This culminates in abstract conceptualization (AC) and generalisations or conclusions, which entail active reflection, intended to generate new ideas or modify existing ones. Active Experimentation (AE) or testing is the last stage in the learning cycle. It entails application and modification of the new experience (Kolb & Kolb, 2017;McLeod, 2017), all of which rely on sensitivity in decision-making at every stage.
Experiential learning cycle integrates experience, reflection, conceptualisation and action, which implies that the Theory perceives learning as an integrated process, revolving around the four stages, all being mutually supportive (McLeod, 2017). Further learning is understood to be an ongoing process, and not a one-off activity with a definite end of single outcome. Even though experiential learning may begin at any stage of the cycle and follow the subsequent stages to a logical conclusion, effective learning can only occur when a learner is able to execute all the four stages of the model. This, suggests that no one stage of the cycle can fulfill experiential learning on its own (Kolb & Kolb, 2017). Further, an experiential learning process is spiral one, which helps students transform their knowledge into skills, rather than a linear that only helps learners acquire knowledge. Whereas the linear model conditions learners to become passive recipients of information, the Theory prepares learners to become active participants in the learning process by posing and answering questions, engaging in Where: n i = sample size, Z = confidence level: 1.96, p = proportion of learners in the third-year: 0.489 and q = proportion learners in the fourth-year (1-p): 0.511. The output was then adjusted for design effects using the correction factor indicated in formula 2: - Where nf = sample size correction factor, n i = computed sample size: 383.97, N i = population: 219. The correction process obtained a sample size of 139 learners. The sample size was divided proportionately between the two strata based on the population distribution, using formula 3: -= * (3) Where n o = stratum sample size; f = the sampling fraction (n i /N i ) and sN o = the stratum population (Kozak & Zieli´nski, 2005). The quotient of computed sample size (n i ) and the target population (N i ) yielded a sampling fraction (f) of 0.6368. Using the sampling fraction, the computation yielded proportionate samples of 68 thirdand 71 fourth-year learners. Stratified random and purposive sampling procedures were applied to sample learners. Primary data were sourced using three types of tools namely, a self-administered questionnaire for learners, an FGD guide also for learners, and a KII guide for instructors. The tools and data sourcing approaches were pilot-tested between February and March, 2018 on second-year learners at the Department.
Both quantitative and qualitative techniques were applied to process and analyse the data. Quantitative analysis was performed using various techniques, including cross-tabulations with Chi-square (χ 2 ) statistic, Spearman's Rank Correlation Coefficient, and binary logistic regression analysis (Wuensch, 2006;Myers & Well, 2003;Nachmias & Nachmias, 1996). Binary logistic regression was applied to determine influence of the context of vignettes on learners' ethical decision-making. Under the model, the predicted variable takes the value 1 with a probability of success represented by θ, or the value 0 with probability of failure represented by 1-θ. In this study, the dependent variable was ethical decision-making, with two possible outcomes, viz. ethically sensitive decisions or ethically insensitive decisions. The model is expressed as indicated in formula (4): - Where Y = the predicted variable, in this case, ethical decision-making; θ(Y) = the probability of a particular learner making an ethically sensitive decision; 1-θ(Y) = the probability of a particular learner making an ethically insensitive decision; α = constant term of the equation; β 1, β 2 …β i = regression coefficients associated with independent variables; X 1 , X 2 ...X i = independent variables and ε i = the error term (Wuensch, 2006). Even though the analysis yielded various outputs, this article focused on β coefficients and Odds Ratios (OR). The Statistical Package for Social Sciences and Microsoft Excel packages were applied in quantitative analysis. Qualitative data were processed and analysed following the three steps prescribed by Best and Khan (2004), namely organization, description and interpretation of data to explain the findings, and put emerging patterns into an analytical framework thus communicating the essence of what the data had revealed (Creswell, 2013) about the perceptions of relationship between vignette context and ethical sensitivity for decision making among the teacher trainees.
The study was conducted in accordance with ethical principles of social science research, including respect for participants' rights to self-determination, voluntary participation and confidentiality (Dench, Iphofen & Huws, 2004) besides receiving the necessary authority from the regulatory bodies.

Results
The results have been organized under four sub-sections, including univariate analysis of ethical sensitivity in decision-making; bivariate analysis of learners' background profile vis-à-vis ethical sensitivity in decision-making; bivariate analysis of the context of vignettes in relation to ethical sensitivity in decision-making; as well as multivariate analysis of the context of vignettes and ethical sensitivity in decision-making.

Univariate Analysis of Ethical Sensitivity Decision-Making
Learners were requested to read the hypothetical vignette presented below and make the most appropriate decision.
You and Lisa are Business Education teachers at Kitenge High School, a mid-sized boys' boarding school. Your department has recently completed setting end-of-term examinations and the head of your department has handed it to you, with the request that you submit it to the examination office. You and Lisa are working late that night when you receive a call from the Principal, who asks you to immediately forward jel.ccsenet.org Journal of Education and Learning Vol. 9, No. 4; him a copy of the draft Business Education examination. When you locate the copy, you discover that your head of department had sealed it and written "Final Copy, Confidential" on the envelope. Your head of department is out of the country attending a seminar and you know it would be impossible to locate him for consultation. The Principal has a son in your class, who is always top of his class. How would you handle the Principal's request?
The purpose of the task was to determine the proportion of learners whose decisions would show signs of adherence to the principles underlying ethical sensitivity in decision-making, including taking ethical responsibility, acting with professionalism, maintaining confidentiality, upholding honesty and showing respect for legitimate authority (Weiss, 2014;Carroll, 1990). The results presented in Table 1 show that of the 116 learners, 24 (20.7%) demonstrated ethical responsibility in their decisions, while 34 (29.3%) acted with professionalism.  Table 1 were aggregated to determine the proportion of learners who were ethically sensitive and those ethically insensitive in their decisions. In this regard, the analysis revealed that 30 (25.9%) learners made ethically sensitive decisions, while 86 (74.1%) exhibited ethical insensitivity in their decisions.
The results in Table 2 show that 73 (61.6%) learners were aged below 23 years, while 40 (34.5%) were in the 23-25 years aged bracket. Among those who were ethically sensitive (n = 30), 20 (66.7%) were aged below 23 years, while 7 (23.3%) were in the 23−25 years bracket. Those who were ethically insensitive (n = 86), included 53 (61.6%) learners aged below 23 years, and 33 (38.4%) in the 23−25 years category. The analysis revealed a significant association between learners' age and ethical sensitivity in decision-making (χ 2 = 10.148, df = 2 & ρ-value = 0.006). In addition, Table 3 summarizes Chi square test results between ethical sensitivity in decision-making and various variables encapsulated by learners' professional and family profiles. The results show that ethical sensitivity in decision-making significantly associated with all the variables constituting learners' professional profile, at three levels of confidence, viz. 90%, 95% and 99%. Regarding family profile, the results show that ethical sensitivity in decision-making is significantly associated with learners' position or order of birth in family. Learners' attributes that did not show significant association with ethical sensitivity in decision-making, were excluded from further analysis because they were less likely to add value to the relationship between the independent and dependent variables.

Bivariate Analysis of the Context of Vignettes and Ethical Sensitivity in Decision-Making
The context of vignettes was measured in terms of five aspects, namely, structural, operational, financial, human resource and marketing contexts. Each context was operationalised in terms of perception statements, against which learners were requested to indicate their perceptions on a five-point Likert scale, calibrated as 'agree strongly', 'agree', 'undecided', 'disagree' and 'disagree strongly'. Learners' perceptions were then cross-tabulated against ethical sensitivity in decision-making. The results are presented as follows.
The first perception statement on structural context vignettes postulated that 'vignettes enhance the ability to make ethical decisions in different structural frameworks'. The results in Table 4 show that of the 116 learners, 62 (53.4%) agreed strongly with the statement, while 32 (27.6%) agreed. Contrastingly, six (5.2%) learners disagreed with the statement, while seven (6.0%) disagreed strongly. Cumulatively, 94 (81.0%) learners affirmed that vignettes enhanced the ability to make ethical decisions in different structural frameworks, while 13 (11.2%) negated the assertion.
In relation to decision-making, of the 30 learners who demonstrated ethical sensitivity in their decisions, 10 (33.3%) agreed with the assertion, while five (16.7%) disagreed strongly. Among the 86 learners whose decisions were ethically insensitive, 53 (61.6%) agreed strongly with the statement, while 4 (4.7%) disagreed. The analysis generated a χ 2 value of 14.023 (df = 4 & ρ = 0.007), which suggests up to 99% chance that learners' ethical decision-making significantly associated with their perception about structural context vignettes.
The third statement about financial context vignettes asserted that 'vignettes expose learners to financial standards necessary in ethical decision-making'. Table 4 shows that 52 (44.8%) learners agreed strongly with the assertion, while 38 (32.8%) agreed. Those who disagreed were 11 (9.5%) learners, while three (2.6%) expressed strong disagreement. Cumulatively, 90 (77.6%) learners affirmed that vignettes expose learners to financial standards necessary in ethical decision-making, while 14 (12.1%) refuted the assertion. Among those who showed ethical sensitivity in their decisions (n = 30), 12 (40.0%) agreed strongly with the assertion, while seven (23.3%) agreed. Those whose decisions were ethically insensitive (n = 86), included 40 (46.5%) learners who agreed strongly with the assertion and 32 (37.2%) who agreed. The analysis revealed up to 95% chance that ethical sensitivity in decision-making significantly associated with learners' perceptions about financial context vignettes (χ 2 = 13.017, df = 4 & ρ-value = 0.011).  Vol. 9, No. 4; logistic regression model so as to determine its influence on ethical sensitivity in decision-making (dependent variable). Learners' background profile attributes were included in the model as moderating factors. Collinearity diagnostics revealed signs of confounding connections between learners' experience in business and duration of business experience. In this regard, duration of business experience was excluded from the regression model in accordance with the principles of collinearity analysis. The results in Table 5 show that learners who agreed strongly that the context of vignettes influences their ethical sensitivity in decision-making were about 3.9 times as likely to make ethically sensitive decisions as their colleagues who expressed a strong disagreement (ρ-value = 0.004, β = 1.355, OR = 3.877, C.I. = 2.087-7.202). The results suggest up to 99% chance that variation between the two groups in terms of the odds of making ethically sensitive decisions was statistically significant. The results further show that learners who agreed that the context of vignettes influences their ethical sensitivity in decision-making had about 2.3 times the odds of making ethically sensitive decisions as their colleagues who indicted a strong disagreement (ρ-value = 0.025, β = 0.854, OR = 2.349, C.I. = 1.386-3.151). In this case, the results suggest up to 95% chance that the two groups were significantly different in terms of the odds of making ethically sensitive decisions. Notably, the more the learners agreed that the context of vignettes influences their ethical sensitivity in decision-making, the higher the chances of them making ethically sensitive decisions, and vice-versa. This brings up the need to teach learners how to understand the contexts in which vignettes are applied within business in order to improve the odds of them making ethically sensitive decisions.
In relation to this, qualitative results indicated that each context of a business setting is unique in terms of core functions and experiences. Participants explained that experiences of the financial context, for example, are different from those of the operational context because of the divergence of their functions. More overtly, the frequency of situations demanding ethical decision-making varies across the contexts, depending on the sensitivity of their functions. In this regard, some participants noted that an employee handling petty cash daily, experiences relatively more scenarios that demand ethical decisions than one assuming operational functions. In the words of a participant, "…the management of financial resources is very sensitive…, it demands a high level of ethical sensitivity in order to make ethical decisions. There are many temptations around handling cash in an organization." Participants further identified the structural context as an area prone to ethical issues that often conflict with organizational strategic orientation.
Qualitative results obtained from key informant interviews (KIIs) and focus group discussions (FDGs) further revealed that most instructors use vignettes inadvertently to teach business ethics, because vignettes were yet to be integrated in the curriculum as instructional resources. Consequently, the use of vignettes to teach business ethics was mainly a personal initiative. Participants observed that even though some course materials contain case studies and stories, most instructors prefer to develop and apply their own vignettes. The challenge is how to align such vignettes to the various ethical contexts in an organization. As noted by one lecturer, "…the concept of vignettes is new, so most instructors don't have detailed knowledge of how they should be applied to various ethical contexts in a business setting. Because of this, there is no telling whether the case studies applied by instructors in their lessons are appropriate for various ethical contexts. Even though most instructors are innovative, there is need for detailed training on the application of vignettes to explain ethical issues in each context of business, be it leadership, finance, marketing, product development or any other area."

Discussion
The study was expected to influence pedagogical reforms and management interventions intended to improve experiential teaching of business ethics at the Department. The information was further expected to support policy discourses at various levels, intended to improve resourcing of the pedagogical reforms, besides spurring more research on the use of vignettes and learners' ethical sensitivity in decision-making in Kenya and elsewhere.
Most learners, 99 (85.3%), affirmed that the marketing context vignettes enhanced their ethical sensitivity in decision-making; followed by 94 (81.0%) learners who cited structural context vignettes; and 90 (77.6%) who mentioned financial context vignettes. Besides, 86 (74.1%) learners stated human resource context vignettes; while operational context vignettes were cited by 83 (71.6%) learners. This suggests that marketing context vignettes influenced most learners' ethical sensitivity in decision-making, while operational context vignettes influenced the least proportion of learners. Consequently, the effectiveness of vignettes as instructional resources in experiential learning varies with the contexts within which they are applied.
Learners' aggregated perceptions about the context of vignettes significantly correlated with ethical sensitivity in decision-making, thereby prompting rejection of the null hypothesis postulating lack of a significant correlation between the context of vignettes and ethical sensitivity in decision-making. In addition, learners who agreed strongly that the context of vignettes influences their ethical sensitivity in decision-making had about 3.9 times the odds of making ethically sensitive decisions as their colleagues who disagreed strongly. Besides, those who agreed that the context of vignettes influenced their ethical sensitivity in decision-making had about 2.3 times the odds of making ethically sensitive decisions as their colleagues who disagreed strongly. In each scenario, variation between the two groups, regarding the odds of making ethically sensitive decisions, was statistically significant. This implies that the more the learners appreciated that the context of vignettes influenced ethical sensitivity in decision-making, the higher the odds of them making ethically sensitive decisions, and vice-versa.
As observed by Dretske (2000), perception and knowledge are connected concepts. As the level of knowledge about a phenomenon improves, perceptions change in a proportionate measure, either positively or negatively depending on social acceptance of the phenomenon in question. Regardless of the direction of change, improving knowledge enables one to develop informed perceptions. Within the milieu of this study, improving learners' knowledge about the context of vignettes is vital for improving their ethical sensitivity and propensity to make ethical decisions. Furthermore, improving learners' knowledge of the context of vignettes is vital for maintaining ethical sensitivity, which is elemental to ethical decision-making.
Moreover, participants identified structural, financial and marketing context vignettes as the key aspects influencing learners' ethical sensitivity in decision-making. Each context is unique in terms core functions, ethical sensitivity of the core functions and experiences demanding ethical decision-making. Instructional materials for experiential teaching should identify and profile such contexts based on the ethical sensitivity of their functions and frequency of scenarios, demanding ethical sensitivity in decision-making. In this regard, contexts with varied experiences and highly sensitive functions should be considered for inclusion in instructional approaches to improve the quality of experiential teaching of business ethics. The richer the instructional approaches, the better the odds of learners making ethically sensitive decisions. However, it is worth noting that the richness of contextual units varies from one organization to the other. Thus, each context requires tailor-made vignettes to effectively equip learners with skills for ethical sensitivity in decision-making.

Conclusion
Most instructors use vignettes inadvertently because this approach has not been integrated in the course's instructional design. Additionally, most instructors lack in-depth knowledge on the application of vignettes in experiential teaching. Although some instructors created and applied vignettes out of innovation, participants could not tell the extent to which such vignettes aligned with Business Education course content and with real work experiences under each context. This implies that instructors at the Department should undergo proper training on the application of vignettes in each context of business for appropriate application in the course unit.
