The Development of Creative Problem Solving Skills Assessment on Photoelectric Effect

Abstract

In order to face disruption phenomena in the era of industry 4.0, creative problem solving (CPS) skills are important to be developed and assessed through learning process. However, there is no existing instrument that can be used to assess students' CPS skills in the physics domain. This study aims to develop the CPS assessment on the concept of a photoelectric effect called the CPSPE test. The CPSPE test can be used to identify students' skills in solving problems related to the concept of photoelectric effect through the stages of exploring vision, collecting data, formulate the challenge, explore ideas, formulate solutions, and formulate a plan. Each step represents divergent thinking and convergent thinking skills. The validity of CPSPE test is obtained through expert judgment (N=3). In addition, the CPSPE test is then tried out to the students (N=32) to determine the reliability of the test items. The results of data analysis show that reliability coefficient is 0.80 with the inter-rater reliability coefficient ranging from 0.39 to 0.72 which indicating high degree of reliability. It can be concluded that the CPSPE test can be used to assess student’s creative problem solving skills. Keywords—creative problem solving skills; assessment; photoelectric effect
