Screen recorder software in Computer Science Teaching
Computer Science Curriculum and Experiment
l, the status of classroom teaching
Most computer science courses are based on multimedia teaching method. The essence of multimedia-based teaching is displaying the content of teaching in a more intuitive way, so that students can accept more easily and produce more profound memories.
At present, the commonly used method is to play “text + image” courseware to explain the theory and display software interface to introduce the functions of software. This can show some content that is difficult to show on blackboard with chalk and language. It plays an important role in computer teaching in the early days. However, with the increase of graphical interface software, some software is more complicated to operate. It is difficult to rely solely on this approach which is hard to reflect the operation process of the software.
Another method often used in computer teaching is to process a live demonstration by teachers. The advantage of this approach is intuitive, dynamic, and effective. However, there are downsides as follows: First of all, teachers display the operating by mouse clicking and keyboard typing with poor interactivity. If teachers do not prepare well, or there are some failures in process, it will make the process of interruption or repeated presentation. In that case, students are difficult to understand the steps absolutely correct; Second, CAI laboratory must have all the software installed, then the machine is not easy to maintain, and the software also slows down the machine performance, so that it will lags machines when teachers are in the presentation. This reduces the effectiveness of the demonstration.
2, The status of experimental teaching
Experimental teaching plays a vital role in the whole process of computer course teaching. Mastering the theoretical knowledge of computer is not enough in learning computer science courses. Experimental teaching is to train students to use computer applications to solve real problems. The significance of computer experiment teaching is so important, that has been recognized by the whole education sector. There are two mainly used experimental teaching methods for computer science course:
The first method is broadcasting the screen recording to all students, and then they do the experiment through their memories. The inadequacy of this method is that students can only see but can not follow the operation. It is very difficult for students to remind the processing steps when they do it alone. In the experiment, teachers have to guide students in individual counseling, repeating the operation so many times. It is inevitable that guidance teacher can not take care of all the students. It is a waste of teachers’ work. The class time is so limited that teachers can not solve all the operational problems for students, thus affecting the effectiveness and the progress of teaching.
For schools with better experimental conditions, teachers demo steps through the projector in the laboratory, and students can solve the problem by following the operation. That is the second teaching method for computer science course. However, because of the difference of computer basic, learning method and learning ability for all students, some students can keep up with the teaching process, while others can not. So teachers need to repeat the same presentation, or only take care of the students of middle level. Some students can not learn as much as they can, and some students can not keep up the situation. This also impacts the effectiveness of teaching.
There are some difficulty in classroom and laboratory teaching. The teaching conditions are improving and teachers are trying to do better, but there are still some deficiencies. These deficiencies are not only reflected in the classroom and laboratory teaching. For operational content, the students are difficult to review and self-learn after class through the difficult text + pictures courseware.
The screen recorder software in the computer science teaching
Screen recorder software is easy to record the onscreen operating into a video or EXE file, and the process of recording and playback can be set arbitrarily. It plays an extraordinary role for teaching computer science courses.
First of all, it totally demonstrates the whole process of software operation. The process is intuitive and dynamic. It makes teaching can achieve a better result. Besides, it solves the problems of “text + image” courseware.
Second, teachers do not have pay attention on screen, and it is free to set up suspensions in recording. That avoids confusion in the process of presentation, and the phenomenon of disruption because of the operational errors or system failures. It ensures the progress of the course.
Third, CAI classrooms do not have to have all the software applications installed. It makes the machine easy to maintain and it does not reduce the performance of the machine.
Fourth, teachers distribute the recorded files of software operating to students in experiment. Students control playback speed and progress by themselves. In this way, it make that students can learn more based on their level, but also bring teachers out of duplication of effort.
Fifth, the recorded results will be (with the voice narration) uploaded to the teaching site. Students can review the document online. For energetic students, they can learn more by themselves.
In general, screen recorder software like DemoCreator enhances the effectiveness of teaching of computer science courses in all aspects. Multimedia-aided teaching is unique, advanced, and highly effective, but not suitable for all the teaching content. How to achieve optimal teaching effect? It should be based on the rational use of the actual needs to achieve the best results. Multi-media-assisted teaching and traditional teaching complements each other when they became Organic combination. Appropriate use of instructional media can fully mobilize the enthusiasm of learning. It cultures innovative ability of students with enhanced learning efficiency. Practice has proved that the screen recorder software bring good results for computer course teaching, no matter in classroom teaching, laboratory teaching and self-learning after school.
