Introduction
Active implementation and use of new mobile devices and learning technologies, design of electronic educational resources of the new generation are defined as strategic objectives of the transition to e-learning and indicators of socio-economic efficiency of the implementation of the current Federal Program for the Development of Education. According to the Federal Law "On Education in the Russian Federation", organizations engaged in educational activities, can also use e-learning, distance technologies in the delivery of educational courses (The Federal Law, 2012). Moreover, all necessary conditions should be created for the functioning of informational and educational environment, which is supported by electronic educational resources, information and telecommunication technologies, appropriate technological devices. Rapid development of web technologies and compact mobile devices provide conditions for e-learning, which is, according to the study (Polat et al., 2006;Bondarouk & Ruёl, 2011), a distant interaction between the teacher and students, which reflects all the components of teaching and learning process and is provided through interactive devices.
Nowadays, one of the most effective types of distance and e-learning technologies is mobile learning (mLearning, m-learning). The analysis of global trends in the use of mobile technologies proves the need for the application of mobile devices in the educational activities for achieving a variety of pedagogical aims and providing remote access to learning resources in higher education process. Mobile learning adds new value to the education process, reflects the trends in modern education by providing instant access to information; it is a new tool in the information society, where a new learning environment is created, regardless time and place.

Methods
The study is based on the results of the following scientific methods: -Theoretical methods: the study and generalization of domestic and international experience in the designing and implementation of mobile learning in higher education system, analysis of the pedagogical, psychological and technical literature on the informatization of education; inference methods; analysis of regulatory documents, federal state educational standards, curricula, programs, etc.; -Empirical methods: survey, comparative benchmarking, statistical analysis of the research results, experimental teaching and learning.

Results
The use of m-learning is becoming common due to many factors: new social needs in modern educational technologies, the development of market economy, improvement of the learning forms and methods (Al-Qahtani, & Higgins, 2013).
Various sources define mobile learning as: -The use of wireless and mobile networks to facilitate, support, enrich learning and provide greater educational coverage (MoLeNET, 2015); -E-learning through the use of mobile devices (smart-phones, tablets, net-books, handhelds, etc.), that provides mobility to students (GOST, 2011); -Educational process in which learners gain educational information being away from the traditional learning environment, or such learning which is based on the use of educational opportunities and benefits of mobile technologies (Toktarova, 2013); -Educational activities through the use of compact and portable devices that allow students to master learning materials more effectively consume and create information (Wexler et al., 2008).
The UNESCO defines mobile learning as the modern ways of supporting the teaching and learning process through the use of mobile technologies, such as handheld computers, MP3 players, smartphones and mobile phones. In this definition, there are references only to technology devices without naming the pedagogical conditions for the implementation of mobile learning.
Analysis of the definitions proves the fact that mobile learning is a many-sided concept. Depending on the goals of the research, scientists study different aspects of mobile learning: theoretical, historical and methodological foundations of mobile learning (Anderson T., Soldatkina V., Tikhomirova E., Lobachyova S., Isaeva Y. et al.); opportunities and principles of the use of handheld computers in education process (Andreev A., Zhukov V., Patarakin E. et al.); experience in designing and application of mobile learning resources (Attevel D., Kuvshinov S., Traxler D., Fedoseyev A. et al.); prospects and opportunities for mobile learning (Kay Alan, Sharples M., Attevel D., Traxler D. et al.).
In order to identify trends in the use of mobile devices and platforms in the higher education environment in Russia, IBS company together with the Russian Public Opinion Research Center have designed and conducted the study in nine federal universities, the aim of which was to estimate penetration rate of mobile devices in the university environment (Ivanchenko, 2013). The target group was students and graduate students, teachers of different disciplines and directions of training and administration officials who are responsible for the implementation of information technologies in the education process. On the whole, the penetration rate of mobile devices in the higher education environment can be defined as very high: 99% of the students and 95% of the surveyed teachers have mobile devices. The most common mobile devices among both students and teachers are laptops (83% and 76%, respectively) and mobile phones with the Internet access (70% and 67%, respectively). Moreover, many users often have two or more devices. However, it should be noted that the use of mobile technologies in teaching and learning process in higher education is not widespread and currently there are no accepted standards and specifications on the implementation of e-learning.
In accordance with the results of the study OELPC (2009), we can point out the main requirements for the organization of mobile learning in education system (4C): -Communication: possibility to communicate through a variety of software tools: e-mail, forums, video-conferencing; -Collaboration: mobile learning tools and software must be ergonomic and easy to use; -Creation: e-learning tools and services must meet the creative needs of the students, such as programming, editing music, video, images and text; -Content: availability of the necessary content for the effective teaching and learning process and the integrity of the discipline.
M-learning technology suggests the electronic environment, which includes computing learning facilities and services, and the availability of web access to them from different mobile devices (Kuvshinov, 2007). M-learning allows to use wireless mobile applications for access to information and educational resources of the university, gives an opportunity to design educational electronic office for students and teachers. All these opportunities lead to academic mobility, personalized learning and differentiation of the learning process (Tremblay, 2010).
Among the most important benefits of the implementation of m-learning in the higher education process we can name the following: -Ubiquity: the possibility of obtaining information online; -Availability: access to personal and learning resources through the wireless network; -Convenience: the possibility to store personal data and necessary learning materials in mobile devices, instant connection to the Internet through a mobile phone; -Personalization: the possibility of personalized learning.
In recent years, special attention is paid to the rapidly developing concept, named as BYOD ("Bring Your Own Device"), which is closely connected with the technology of mobile learning. The implementation of BYOD in teaching and learning process involves the introduction of technologies and services into the university educational environment which are focused on providing personalized access to information resources through mobile devices (curricula and programs, academic progress and attendance reports, results of the session, workload, timetable for a student and a teacher etc.); provision of distributed online access to content (podcast broadcasting, webinars, electronic magazines, personal library of educational and scientific resources, social media, etc.). Successful implementation of BYOD as a component of IT strategy of the higher education institution is due to the following factors (Ivanchenko, 2014): -High level and dynamics of the spread of mobile devices in the student and teaching environment and sustained interest in their application, formed by outside socio-psychological factors; -Significant cognitive potential of the students of a higher education institution, who are flexible enough and appropriately respond to changes in the established practices of the education process organization and easily adapt to new approaches and technologies; -Learning materials can relatively easy be turned into media content and the content for interactive mobile services; -Mobile services and content can be easily enough integrated into the infrastructure of educational and research space, both technologically and methodologically.
It is evident that education quality depends on the technologies which are applied to the teaching and learning process. Software for mobile devices interacts directly with the user, provides a link between students and educational system and greatly influences both the user's perception of the learning process in general and its final results. Developing and designing effective mobile applications is a complex process that involves multiple tasks. There are a number of modern tools and technologies to achieve a high level of developing and designing applications. In this connection, there are new requirements for the designing and developing educational mobile applications to make their implementation in the education process effective: -Integration with various systems and e-learning services, for example, through the tools of joint activities and the feedback from a teacher (video conferencing, webinars, podcasts, etc.); -Provision of the academic integrity and necessary amount of content for the effective learning and educational process; -Delivery of learning materials in various forms and formats, depending on the preference of the student (text description, videos, audio lectures, and others); -Provision of calculation functions, editing, visualization and modeling while connecting mobile devices to measuring instruments, various multimedia and office equipment; -Ergonomics, simplicity and possibility to work with the educational web application easily and quickly; -Stability, reliability and productivity, which provide effective and high-available operation of the application to a large number of students at the same time.
These factors lead to the increase in the number of tasks for mobile applications and their complexity. Consequently, one of the main aims of developing and designing mobile applications is to make them effective for supporting teaching and learning process.
In view of the above requirements, the Applied Mathematics and Informatics Department of Mari State University has developed and introduced m-learning system "Programming Mobile Applications for Android" into teaching and learning process of the university (Toktarova & Blagova, 2014). It is an interactive learning system designed to deepen and consolidate the knowledge and skills of students in the field of programming www.ccsenet.org/res Review of European Studies Vol. 7, No. 8;2015 mobile applications for Android.
Android is the operating system for smart-phones, tablet computers, e-books, digital players, watches, game consoles, net-books, smart-books and other devices (Android, 2015).  -Methodological support and possibility of feedback from the teacher.
The modular approach provides the flexibility and openness of the curriculum, that is, it provides students with opportunities to master learning materials of the whole training course in any sequence. In addition, while designing and analyzing the course structure we have defined such characteristics of the system as significance of the element in its structure. The number that characterizes current connections is called rank. While designing the structure of m-learning system, modules with high rank require careful didactic design. For example, elements 1.1-"Kernel level" and 1.2-"Library level" have highest dominance value, that is why they were paid more attention; both the content of information frames and quality control of students' knowledge of course materials have been carefully thought out.
In accordance with the functional purpose, the following components of the learning system were defined. Theoretical subsystem is the main part of the system and is represented in the form of lectures that cover the most important and significant aspects of the studied material. The lecture course is built on a modular basis, allowing the user to determine not only the optimal sequence of studying the material, but also a comfortable www.ccsenet.org/res Vol. 7, No. 8;2015 pace of study. Additionally, audio and video lectures, presentations, lecture notes are designed for each chapter. Practical subsystem is represented in the form of laboratory work on the topics of the study units. It is designed to complement theoretical studies, demonstrate how knowledge taught in lecture courses can be put to use, provide and improve students' professional skills in the field of mobile application development. Laboratory work, in accordance with the theory of the gradual formation of knowledge and skills can be of three types of activity-oriented base (AOB): complete (all required orientations for performing an activity are included); incomplete (only main orientations for task solution and the example of the final result are given); invariant (general orientations are given). Control subsystem includes all the test materials: tests, examination tasks; it aims at quantitative and qualitative assessment of the level of mastering learning materials. After passing the course a student is given a detailed report, which includes the final assessment, the percentage of correctly performed tasks, indicator of the level of mastering the material, quality coefficient of mastering knowledge, time spent online during the studies, as well as a list of topics that should be revised. Additional information subsystem contains orientations for mastering the material, the user manual for the computer system installation and maintenance instructions.

Review of European Studies
The general model of teaching and learning process on the basis of m-learning system "Programming Mobile Applications for Android" is presented in Figure 2.
While developing the computer learning system, Java client-server technologies have been used, which have enabled to design versions for computers and a variety of mobile devices, provide access to Web services of communication (forum, chat, blogs), hold webinars, audio and video conferences, provide social interaction in educational networks and communities. The system provides three user access levels: administrator, teacher and student. The following review functions are accessible to the teacher: the performance rating of students, making a detailed report on the results of laboratory and tests performance, choice of the level of individual tasks for each student or group. In addition to working with learning materials and assignments, in a user account the student has an access to the results of laboratory work and tests with the possibility of unloading a detailed report as well as communicates with the teacher via the feedback form.
