In April this year, the Ministry of Education released the "Action Plan for Education Informatization 2.0", which will basically achieve the development goals of "three fulls, two highs and one big" by 2022. Yang Nianlu, executive vice president of the Chinese Education Society, proposed that there will be four changes in education in the future: from unity to diversity, from commonality to individuality, from subject-based learning to integrated learning, and the development of classrooms from low efficiency to high efficiency . These changes are inseparable from the support of informatization.
Today, with the deepening development of education and teaching reform, how can teachers use information technology and tools to achieve "light weight and high quality" teaching? To reduce the burden of students' work and improve classroom efficiency, each teacher is required to continuously sum up thinking, improve skills, make full use of information-based teaching tools, and do a good job of "three fights before class and three classes after class" to achieve a true "high burden" quality".
Light burden: do a good job of "three spells before class"
"Three spells before class" refers to spelling lesson plans, courseware, and exercises before class.
1. Fighting plan
First, based on your own understanding of the textbook and the starting point of the students' knowledge, determine the teaching objectives and prepare the lesson independently without referring to any materials.
Secondly, find 2 ~ 3 excellent lesson plans to study, compare and reflect with your own lesson plans carefully, and see which ones you have and others do n’t, and which are the subtleties of others that you have n’t thought of, so as to discover your own Loopholes, extract the essence of others.
Finally, reorganize and improve the original lesson plan. Accurately grasp the starting point of students and the major and difficult points of teaching, learn from each other's strengths and make shortcomings, and constantly adjust.
The way of "spelling lesson plans" is conducive to improving teachers' independent thinking ability, so how to quickly find excellent reference lesson plans? Nowadays, there are many information-based teaching aids on the market, and teachers can reasonably use teaching aids to find excellent teaching plans and reduce the burden of lesson preparation.

Second, spelling courseware
Excellent courseware not only helps to attract students' attention, but also helps teachers explain the difficulties of teaching. Especially for abstract and difficult-to-understand mathematics, physics and other subject knowledge, teachers often use multimedia to demonstrate the analysis process of knowledge points intuitively. Therefore, teachers can collect more courseware from the Internet, piece together the links that they think are better, and find the best presentation method.
For example, in the teaching of "three-dimensional expansion and reduction", knowledge points related to spatial logic are more difficult to explain, and the effect of using only blackboard writing will be very general. PPT courseware such as Figure 2 can use a three-dimensional model to visually present the expansion and reduction process of the cube, providing students with a demonstration between abstract concepts and visual objects, so that students can more directly understand the basic knowledge of cube expansion and reduction.

Three, spelling exercises
Before preparing a lesson, the teacher should sort out the error-prone points of each lesson to make the subject design more targeted. In addition, teachers should first do the exercises themselves, which is helpful to understand the knowledge points involved in the questions. There are many teaching aids and problem-solving tools on the market, and teachers can find suitable topics from them. The types of question-finding can be generally divided into three categories: finding students who are prone to wrong questions and consolidating the foundation; exercises that are slightly higher than the knowledge points of the textbooks for students who have the abilities to learn; and finding some types that are rare in the past to broaden the students' horizons.
Now, many teachers will use the exercise website and exercise APP to set classroom exercises or homework, which saves a lot of time and energy for preparing lessons. For example, 101 Education PPT has a large number of genuine exercises and test paper resources built-in, which can be directly inserted into the lesson preparation courseware to facilitate the interaction of exercises in the classroom.
After choosing a good problem, we must pay attention to the way of practice. Teachers are advised to take error-prone questions related to knowledge points as the main type of practice in the classroom, and use the picture fast-transmit function in the teaching software to project the students' answers on the big screen and analyze them one by one. Questions with a high error rate can be accumulated into test papers and used for examinations in order to consolidate knowledge again.

High quality: do a good job of "three clear after class"
"Three cleansing after class" refers to clearing corrections, tutoring, and knowledge after class.
1. Clearing and correcting
In order to accurately understand the student's knowledge mastery, the student's workbook should be cleared every day, every day, and this book. Want to do this easily, the secret lies in the layout of the work. So, how to arrange the work?
1. Do a good job of three exercises before class, which can greatly reduce repetitive assignments, so as to ensure that most of the students' homework can be completed at school.
2. Difficult questions should be done in school as much as possible, so that teachers can solve the problems in time.
3. The homework to take home is relatively simple, try to be a problem that students can complete independently.
Second, clear counseling
Students can generally be given 5 to 15 minutes of independent homework time in the classroom. The quality of homework in the classroom is much higher than the quality of homework done in the next class.
In the classroom, we must pay attention to the tutoring of the less advanced students, and every attempt and simulation are based on their results. At the same time, students who do not have knowledge points should be encouraged to raise their hands in a timely manner. If there are a large number of students, students can be practiced again, so that the implementation of each knowledge point is in place. In addition, there are two advantages to practice in class. One is that the students are more concentrated in the class and the effect of the practice is better. The other is that they can give timely comment exercises in the class, find the students ’weak knowledge points in time, and provide targeted guidance.

3. Clear knowledge
1. Student clearance
For students' learning errors, in addition to timely feedback in the classroom, they should also often guide students to reflect on their errors and make statistics on wrong questions, so that students can compile knowledge that is not well mastered in normal or review into "mistakes" "Review paper" is helpful for students to re-understand mistakes.
2. Teacher Clearance
In teaching, teachers should pay attention to the organization of knowledge. After the completion of each unit, the unit will be summarized around the most difficult knowledge points, attention points and confusion in the teaching of this unit.
At the end of each unit, the error-prone questions should be sorted out. At the end of the final review period, the teacher does not need to spend a lot of time and energy to find the problem, just classify the usually sorted questions according to different knowledge points, first review in blocks, master each piece of knowledge, and finally integrate them for students to practice. Too.
The problems found in the errors of the students 'work should be summarized, summarized, and sorted out, and used to guide the students' learning. This not only allows students to better master knowledge and improve academic performance, but also helps teachers improve teaching methods and improve teaching quality.
"Three spells before class and three classes after class" can enable teachers to improve classroom efficiency, reduce students' learning burden, and truly achieve "light weight and high quality". The use of educational informatization tools makes it more convenient and effective for teachers to practice "three spells before class and three classes after class". 101 Education PPT is a highly recommended preparatory teaching tool. Efficient preparatory teaching methods and rich educational resources can allow teachers to enjoy the preparatory teaching process. At present, 101 Education PPT software promises to be free for individual users, and can be downloaded and used by directly searching "101 Education PPT" on the web.
