Today's elementary schools emphasize practice- and learner-based computer courses. However, the excessive number of students, poor class environments, and lack of proper lesson plans make it hard for such classes to be properly taught. Also, there are also other problems that decrease the quality of the subject: learners at different levels, lacking in background knowledge in the computer, difficulties for teachers to control the entire class due to students' lack of focus, and the unfavorable student/teacher ratio.
In this research, we found solutions to the above issues by adapting a demonstration/practice teaching method led by numerous teaching assistants, expanding lessons tailored to each student's own level.
We chose three classes from fourth graders at Andong Y Elementary School as the subject for this research. Through this research, we have analyzed the students' study results, self-efficacy, and the response and interest in the computer course by examining three groups of students: the first group led by a teacher's demonstration and practice the second group by a teaching assistant's demonstration and practice and the last by numerous teaching assistants' demonstration and practice.
As a result, the first group of students led by a teacher and the second group of students by a teaching assistant showed differences in the average study results, but no major differences statistically. However, the first group of students led by a teacher and the third group of students by numerous teaching assistants showed remarkable differences in the average study results. The second group and the third group showed major differences in the level of self-efficacy, whereas the third group showed a higher level of response and interest in the computer course than the first group, indicating a way to raise the quality of the course.
As a result, we were able to prove that a computer course taught by numerous teaching assistants will help not only induce an interest and motive for a mutual learning environment among the students, but also bring positive effects on the study results and self-efficacy.
