A brief discussion on how to effectively combine lecture notes and PPT courseware

It is one of the best ways to improve the quality of teachers and cultivate research-oriented and scholar-oriented young teachers. Through lectures, teachers can talk about their teaching intentions, methods and purposes of handling teaching materials, so that teachers can better understand how to teach and why they should teach in this way. Making courseware with PowerPoint is simple and easy to learn; and in a Windows environment, PowerPoint is the most convenient tool for creating presentations and supports video and sound. Multimedia such as tables, images, sounds, text files, etc. can be inserted into the slides of the presentation. information. If the two are organically combined, the theme of the lecture will be clearer, the focus will be more prominent, and the effectiveness of teaching and research activities will be improved. Text-based lecturing is when teachers verbally state the teaching ideas and theoretical basis for specific topics. That is, on the basis of lesson preparation, teachers talk about their teaching design to peers or teaching and research personnel, and then the listeners comment to achieve mutual communication,* **A teaching research and teacher training activity with the same purpose of improvement. Simply put, lecturing is when a teacher verbally expresses his teaching ideas and theoretical basis for a certain point of view, problem or specific topic. How can we make lecturing play a greater role, so that teachers who attend lectures can better understand how to teach and why they should teach in this way, so as to make the theme of teaching and research clearer, focus more prominently, and improve the effectiveness of teaching and research activities? Personally, I think lecturing should be used The draft and PPT courseware are organically combined. Taking advantage of the PPT courseware's large amount of information, strong intuitiveness, and easy to attract other people's attention, the content of our lectures can be displayed in the audience's eyes in a three-dimensional and layer-by-layer manner. In front of you, help the listeners understand efficiently. 1. Use powerful lecture notes to support PPT courseware. We can use PPT to easily create eye-catching slides, but to some extent, the ease of use of PPT courseware has also become its most fatal weakness. We must know that the audience does not come just to watch what is displayed on the screen. Images are more about listening to your lectures, so PPT does not exist independently. Although we need to build a powerful set of PowerPoint programs, we should also ensure that your oral explanations are equally engaging. For example, when presenting the basic steps of teaching such as "Teaching materials - teaching methods - teaching methods - teaching procedures - writing on the blackboard", PPT courseware can present these basic steps in the form of an outline, so that at a certain time To the extent that the lecturer has more time to explain and explain, the listeners will not feel clueless and can easily accept the key points and difficulties of the lecturer, intuitively understand the content of the lecture, and arouse in-depth thinking. . However, PPT courseware cannot overwhelm the competition. We should not pile up all lecture content and display it on PPT courseware. In this case, the lecturer will be simply redundant and there is no need to exist. Not only that, but it can make even the most visually appealing presentations dull. We only need to present the key words and phrases in front of the listeners, so that the courseware can play a truly supporting role. Therefore, PPT courseware can only achieve the best effect when paired with vivid lecture notes and arouse the excitement of the listeners. 2. Let PPT courseware bring vitality to the lecture notes. The target of our lectures is not students, but fellow teachers. Therefore, it is not appropriate to explain each process in too much detail during class. Instead, we should focus on how to implement the teaching process, how to guide students to understand concepts and master rules, and how to cultivate students' learning abilities and improve teaching effects. Lectures should focus on rationality, and lectures should focus on perceptuality and practice. It is not easy to complete the lecture content in a very limited time. It must be detailed, simplified and traditional, and the degree of explanation must be accurately grasped. It is too detailed and too complicated, time does not allow, and it is not necessary; it is too brief and too simple, and the basic content cannot be stated, and the audience will not be able to accept it. How to make the listeners understand what the lecturer said faster in the limited time, we can use PPT courseware to bring vitality to the lecture script. For example, when reflecting the key contents of the course manuscript, the layout design of the slides we produce should be similar to that of blackboard writing, with clear outline levels, reasonable form structure, well-proportioned layout, accurate content, complete and smooth text expression, and appropriate size and color. , the whole slide is neither empty nor complicated, good and not complicated, clear and beautiful.

To this end, the lecturer should carefully conceive, repeatedly deliberate, and carefully design according to the purpose of the lecture, or use an intuitive framework structure, or use a table format, etc.; and then use the slide hyperlink command to link each knowledge point with the knowledge point Linked to the slides below. When the lecturer talks about the five aspects of the lecture content in detail, we can also set link buttons after these contents. The link buttons for each process are presented in order according to the lecturer's explanation; at the same time, in the slide presentation, if the link buttons after the knowledge points always remain on the slide after being presented, the slide content will appear confusing and interfere with the slide presentation. The visual effect of the lecturers causes the topic slides to fail to highlight the key points and difficulties. To this end, we must make full use of the "custom animation" command of PowerPoint to reasonably set the "sequence and time" of the object's projection, and the reasonable setting of the "effect" of the object's projection, etc., so that the theme slide knowledge points and the attached link buttons Render sequentially as required, and have the link button automatically hide when the next content is rendered. In this way, the active slides can attract the attention of the lecturers, refreshing them, allowing them to understand the theme of what you want to say more quickly, and make timely judgments. 3. Insert videos to provide auxiliary explanations to the lecture notes. Since teaching activities are carried out around the key points of teaching, the key to teaching activities is to break through difficult points. Therefore, when explaining the teaching process, lecturers must make more efforts on how to highlight key points and how to overcome difficulties. The lecturer's words alone cannot allow the listeners to fully understand how you handle the teaching content, how you choose the teaching methods, how you achieve the teaching goals, etc. How to let the listeners know in time whether the teaching design can achieve the expected teaching effect? I think we can use the method of inserting videos into courseware to assist in explaining the lecture notes. For example, the fifth link in the textbook is the teaching program. The teaching program is the systematic development of the teaching process, which is expressed as a time sequence for the advancement of teaching activities. In other words, it is how teaching activities are introduced, how they are launched and how they are ended. According to the general process of students' learning activities, the sequence of the teaching process is generally the introduction of new lessons, new lesson study, class summary, consolidation training, etc. Expounding teaching procedures is the focus of lectures, because the processing of teaching content, the selection of teaching methods, and the achievement of teaching goals are all achieved through this link, and the teacher's teaching philosophy must also be reflected through it. So, how to explain the teaching process in lecture activities? We can turn the teaching program into a lesson, record it as an image, make a video, and insert the video into our courseware. When the lecturer explains the design of bilateral teaching and learning activities, after explaining each process, the students' learning situation is more intuitively displayed through the video, so that the listeners not only understand how the lecturer teaches, but also understand whether the students are Actively participate in learning activities under the guidance of teachers; what emotional reactions students often make during learning activities; whether students are willing to participate in thinking, discussion, debate, and hands-on operations; whether students often actively ask questions; whether the time for student activities is Sufficient and appropriate; whether students have developed self-study habits, reading habits, and writing habits; how students analyze and solve problems, etc. This will not only enhance the diversity and visual appeal, but also allow the listeners to accurately grasp the actual classroom standards of "teaching and learning", analyze the efficiency of students' classroom learning, and obtain first-hand classroom teaching materials. Lay the foundation for you to take the same class well in the future. In short, with the continuous development of multimedia technology and the popularization of computer-assisted teaching, multimedia courseware is also playing an increasingly important role. We teachers should correctly understand the relationship between multimedia courseware and effectively combine the courseware with our lectures to improve the efficiency of the classroom.
