Abstract
Utilising practical work in physics learning can enhance students’ understanding of abstract concepts and theories. Students need to have good mastery of practical skills so that practical work is effective in enhancing learning. In Malaysia, students’ practical skills are assessed through school based assessment and written test, which emphasize on the written work produced by students. However, there is no specific guideline to assess physics practical skills which should be assessed in the actual setting where practical work is being carried out. This study suggests two different modes of assessment, direct observation and written test, to be used in measuring students’ physics practical skills because practical skills are multidimensional and single method cannot provide comprehensive information on the ability of students in performing practical work. In this study, physics practical skills are grouped into the domains of Design, Execution, Analysis and Evaluation. Hands-on practical tasks and scoring rubrics are developed based on the hypothetical-deductive model to measure students’ physics practical skills by the mode of direct observation. Written test is developed as a second mode of assessment. The validity and reliability of the instruments developed were checked with different methods and were found to be of sufficient content validity, construct validity and internal consistency. The instruments were administered to 153 Form Four students from 10 secondary schools in the division of Kuching, Sarawak. The findings of this study indicated that there were weak correlations between the two modes of assessment.
Students’ mastery of physics practical skills is at a moderate level and their performances differ in different tasks and domains of practical skills.
