Abstract: The mathematical foundation of secondary vocational students is generally weak, the students' learning consciousness is relatively poor, and the class schedule of mathematics courses is limited, which makes it difficult for secondary vocational students to improve their mathematical performance and affect their enthusiasm for learning mathematics. With the development of Internet technology, teachers can use the Internet to help students prepare mathematical knowledge, explain homework, and accurately help students in need. This article explores online assistant teaching and aims to improve the effectiveness of secondary vocational mathematics teaching.

Keywords: secondary mathematics; network assistant teaching; teaching effectiveness

The mathematical foundation of secondary vocational students is relatively weak, the interest in mathematics learning is not strong, and the teaching efficiency of mathematics classroom is low, which is an urgent problem to be solved by the majority of secondary vocational mathematics teachers. At present, with the continuous development of China's Internet technology and the introduction of various application software, with the help of network auxiliary teaching, improving the teaching efficiency of secondary mathematics is one of the topics worth studying at present. The author first used the interview method to do a survey, and found that some students still want to learn mathematics well, but the mathematical foundation is relatively weak, and the response is somewhat slow; some students cannot understand the explanation of each homework, because the teacher's class time is tight and the lecture speed is fast; for students who are in difficulty, the previous knowledge is basically not, and they need to be tutored alone; and some students reflect that the test is too small and cannot find their own deficiencies in time. In view of the problems found in the above survey, with the help of network auxiliary teaching, the author strives to improve the effectiveness of secondary vocational mathematics teaching, and has made the following explorations.

First, use online teaching videos to help students prepare mathematical knowledge

Secondary vocational mathematics class 4 to 5 lessons per week, the foundation of students is relatively weak, only by the teachers in the classroom to explain, most of the students are not easy to learn thoroughly, which requires students to prepare before class. Secondary vocational students are not self-conscious, and many students are reluctant to read books by themselves. According to their psychological characteristics, the author uses the online video teaching resource - Beijing Digital School to help teach mathematics. According to the teaching content of the new lesson, the author found the relevant videos in the Beijing Digital School, assigned students a "watch video" pre-study homework, let the students learn it themselves before learning new knowledge, and asked parents to help supervise, no matter how they must insist on listening. Listening to it again may not be very smooth, or it may only be able to understand part of it, but students will have a preliminary impression of key concepts and formulas, and listening to the author again in class will reduce the difficulty of their understanding, making it easier for them to grasp new knowledge, which will improve their mathematical learning efficiency, and the efficiency of classroom teaching will also be improved. Through pre-class preparation, students increase the number of speeches in class, their enthusiasm increases, their usual grades are also improved, and then their learning interest is enhanced, forming a virtuous circle of mathematical learning.

Second, use the Network to explain weekend homework

The cultivation of students' learning ability is through training, and mathematical learning will not form ability by listening only to lectures and not doing problems. According to the psychological characteristics of secondary vocational students, the amount of homework left every day should not be too much. Their study habits are not good, they are reluctant to write homework, they are only willing to copy homework, and they have limited time to explain homework in class the next day. Therefore, in order to improve the efficiency of students' problems, the author usually leaves less homework, and the amount of homework left for students every Friday is larger, so that they can accept it. In order to solve the problem of tight class lecture time, the author uses the time from 7:00 to 9:00 pm every Saturday night to explain the weekend homework to students through the DingTalk group. Students can interact with the author Lian Mai in the group or ask questions. Due to the relatively abundant time, the author's lecture speed is slow, and the questions are answered at any time, and it is easier for students to understand. The author asks students to correct their homework before 10 p.m. and pass it to the DingTalk group, and the class representative counts the grades. Through this method, students were answered questions in a timely manner and the efficiency of mathematics teaching was improved.

Third, use the network to conduct family tests

Tests are the "magic weapon" to supervise and test students' learning effects. The family test time is generally arranged on Friday night, a test has a total of ten questions, the content of the question is the focus of the week's learning, the form of the question is mainly multiple choice questions. The author uses the questionnaire star platform as an answer card and requires students to complete it within the specified time. When the students have finished answering the questions, the questionnaire star platform will automatically display the students' test results and the wrong question numbers. Every Saturday, the first 30 minutes of the live webcast lecture time for students are explained to explain the questions of the previous day's family test, so that timely feedback impresses students and improves the efficiency of mathematics teaching.

Fourth, use the Network to tutor students in need

Students' learning ability and learning foundation are different, so their learning level is also uneven. As a math teacher, tutoring students is an essential job. Counseling students with difficulties is divided into two ways: common counseling and personality counseling. Common counseling, that is, the common problem of most students with difficulties, the author sent to the group of mathematical students in the form of micro-lessons, for them to make up for them, improve their learning efficiency; for a very small number of students with difficulties, whether it is psychological problems or learning problems, the author uses WeChat to help them and carry out one-on-one counseling. To this end, the author also specially prepared a handwriting board to solve the problem that mathematical symbols are not easy to write. Through targeted network individual counseling, the learning shortcomings of students with difficulties have been made up, the problems in their learning have been solved, and the efficiency of mathematics teaching has been improved.

Fifth, use the network to carry out home-school collaborative education

In order to successfully implement education for students and achieve excellent results, it is necessary to cooperate with parents in education. For example, students watching video previews in Beijing Digital School at home, and students with difficulties watching remedial micro-lessons at home require parental assistance and supervision. To this end, the author has established a parent dingtalk group to publish students' homework so that parents can help supervise in a targeted manner. When lecturing students, the author conducts multi-group simulcasts to let parents see the content of the author's tutoring for students. The author also uses network software to hold parent-teacher meetings, parent-teacher meetings for all students, parent-teacher meetings for individual students with academic difficulties, and tripartite exchange meetings for parents, students and teachers. A variety of methods to unite with parents, so that parents can participate in teaching activities together and improve the effectiveness of mathematics teaching.

After a period of practice, the students' learning initiative has been enhanced, and the cooperation of parents has been increased, effectively improving the effectiveness of secondary vocational mathematics teaching. This is the practice of helping to teach with the help of the Internet, which fully reflects the rapid development of China's scientific and technological level. In the next step, I will continue to study other strategies of online assistant teaching.
