Seven, learning network
1, "Learning Network" is a comprehensive tutoring system based on students' information education, which diagnoses and guides students' academic level online.
2. The system invites outstanding educators such as special and senior teachers and academic leaders who work in the front line of teaching to write high-quality and high-level test papers according to the existing teaching materials and closely combined with the syllabus. By means of information and online network, students' mastery of basic knowledge and skills in the learning process is detected. Diagnose students' defects in knowledge, skills and learning methods, help students check and fill gaps, and enhance their autonomous learning ability. According to the report form fed back by the system, we can dynamically know what level the students' current level is among the students of the same grade who participated in the test. At the same time, the system will give students detailed feedback and guidance according to the evaluation results, help students understand the knowledge points that need to be supplemented and strengthened, prevent deviations in learning, and guide students to improve and optimize their learning methods.
3. The "learning network" system, with the new mode of triple combination of "learning", "extension" and "testing", consolidates the knowledge points learned by students in an all-round way, avoids students' resistance and aversion to flat learning methods, enhances their interest in learning, enables students and parents to fully understand their current learning level, and guides students to review in a targeted manner. It is also interesting for children to learn through games and other ways.
