1. Features of educational apps
Compared with traditional classroom learning, mobile learning based on various educational apps can get rid of the constraints of fixed time and space, and learners can instantly search, send and share all kinds of learning information, thus easily realizing the "5W" free learning state of learners at any time and any place. Compared with the traditional educational resources, the mobile educational APP has the following six remarkable characteristics: (1) mobility, that is, the educational APP has good mobility and online, and it can transform many teaching events originally performed in a specific place into execution in any place according to the individual needs of learners, which brings many conveniences for learners to learn deeply and effectively; (2) Socialization, that is, the mobile education APP generally has the function of community communication, so that students, teachers and parents can quickly get to know each other in reality through the APP, and communicate with each other on the Internet or in real life, so that teachers and parents can share their educational experiences with each other. At the same time, learners can also carry out corresponding social activities around the theme of education and teaching, which greatly enhances the mutual learning experience and writing exchange experience between learners; (3) gamification. In the mobile education APP, game elements are generally integrated into the teaching process, and the teaching content and games are organically integrated, so that learners can learn actively and happily through entertaining; (4) Individualization, each learner's learning style, cognitive structure and way of thinking are different. The best education is to provide information with different difficulties to people with different learning characteristics in a flexible way, so that learners can get comprehensive and distinctive development. This is the basic requirement and characteristic of personalized education. Mobile education APP can provide learners with the opportunity and platform to set a suitable rhythm, and can meet the diverse personality needs of different learners as much as possible; (5) intelligence. The intelligence of mobile education APP is reflected in the following three aspects: First, in terms of learning methods, APP generally has the functions of intelligent push of learning content, multi-interface adaptation, multi-screen integration, breakpoint continuous broadcast and so on, which can ensure the smooth dissemination of teaching information; Second, in terms of evaluation methods, APP can select relevant evaluation content and test it according to learners' learning behavior, and at the same time, it can analyze learners' defects and recommend learning paths according to the process; Third, in terms of communication methods, APP supports online questioning and automatically collects typical questions, and encourages students to share their learning experiences with each other. (6) Interactive situation. Educational mobile app pays more attention to the creation of learning situations and human-computer interaction activities, and strives to help learners understand and absorb various multimedia information content more deeply through them. Even many educational APP products use virtual simulation technology, which allows learners to collect information and evidence in real or simulated learning situations, guide learners to explain problems scientifically, and let learners actively learn and actively participate in various teaching interactions.
2. Common classifications of educational applications
1. Teaching guidance for primary and secondary schools
2. Children's cognitive enlightenment
3. Foreign languages
4. Vocational education examination
Different types have slightly different emphasis on planning and development.
Three. Some common functions:
1. Registration and growth of student information
2. Introduction and description of the course
3. Course purchase and expiration reminder
4. Online course viewing and interaction
5. Online answer and score statistics
6. Academic evaluation
7. Notification and consultation
4. Main development difficulties:
1. Update difficulty:
As we all know, the content of educational apps is huge and complicated. In particular, the APP used by students has both mathematical formulas and chemical graphics; There are both ancient Chinese exercises and foreign language exercises, and the teaching contents of different grades are different. Not to mention dividing it into daily study and examination. Students need to submit their homework and teachers need to grade it. Therefore, the daily update of an educational APP has become a difficult point in development, which is not only large in quantity, but also different in update interface layout.
2. Many difficulties:
Another difficulty of educational APP is multiterminal. An APP generally has at least two ends: students and teachers, and sometimes parents. Needless to say, the difficulty of multi-terminal development, the cost and time of development will rise.
When developing educational multi-terminal APP, we will encounter another problem, that is, many functions can be reused in multiple terminals, such as homework and exercises. If they are all repeated development, it will consume a lot of development time and cost. "
