The first purpose of this study is to distinguish difficult chapters in ‘Speed of objects’ chapter and find the factors which give difficulty to the teachers and students. Also, it attempts to compare the students’ assessment scores with the degree of difficulty in teaching and also with the degree of difficulty in learning. This report is expected to help science teachers develop their PCK(Pedagogical Content Knowledge) for teaching the chapter professionally. 15 teachers who had taught the ‘Speed of Objects’ chapter and their 386 students took part in the survey to acquire information about the difficulties in teaching and learning. 386 students also received a test to examine their understandings of the chapter. The results of this study are as follow; First, the degree of teachers’ and students’ difficulty is only affected by the contents, and the degree of onerousness felt by teachers is higher than that of students. Second, The topics caused higher difficulty to teachers were ‘Understanding the meaning of motion(2nd lesson)’, ‘Understanding the meaning and unit of speed(5th lesson)’, ‘Changing unit of speed(6th lesson)’, ‘Drawing a distance-time graph(7th lesson)’, and ‘Understanding the relative motion(10th). The topics that led higher difficulty to students were the contents of 5th, 6th, and 7th lessons. Third, the ‘Speed of Objects’ chapter can be divided into 4 types of difficulty according to the degree of teaching and learning; ‘Strong difficulty’, ‘Learning difficulty’, ‘Weak difficulty’, and ‘Teaching difficulty’. Last, students showed low achievement to the tasks that were related with ‘Strong difficulty’ and ‘Teaching difficulty’.
Abstract
The first purpose of this study is to distinguish difficult chapters in ‘Speed of objects’ chapter and find the factors which give difficulty to the teachers and students. Also, it attempts to compare the students’ assessment scores with the degree of difficulty in teaching and also with the degree of difficulty in learning. This report is expected to help science teachers develop their PCK(Pedagogical Content Knowledge) for teaching the chapter professionally. 15 teachers who had taught the ‘Speed of Objects’ chapter and their 386 students took part in the survey to acquire information about the difficulties in teaching and learning. 386 students also received a test to examine their understandings of the chapter. The results of this study are as follow; First, the degree of teachers’ and students’ difficulty is only affected by the contents, and the degree of onerousness felt by teachers is higher than that of students. Second, The topics caused higher difficulty to teachers were ‘Understanding the meaning of motion(2nd lesson)’, ‘Understanding the meaning and unit of speed(5th lesson)’, ‘Changing unit of speed(6th lesson)’, ‘Drawing a distance-time graph(7th lesson)’, and ‘Understanding the relative motion(10th).
