Abstract

This research aims to develop an instrument that measures students' critical thinking skills in physics learning to test its validity and reliability using the Rasch Model. The instrument is called the Critical Thinking Test on The Light Waves Concept (CT-LiWa). The novelty of this research is to create a new instrument that is applied to the concept of light waves. The target of this instrument is high school students in one of the provinces in West Java. This research method uses the ADDIE model involving 72 high school students from West Java, Indonesia. The instrument used is a validation sheet and the CT-LiWa consists of 15 items in the form of descriptions. The trial results data were analyzed using the Rasch Model assisted by the Winstep program to obtain the quality of the instrument, namely reliability, validity, and level of difficulty. The results of the analysis show that the CT-LiWa test is not reliable but has a good validity of 27.6% in the fulfilled category with varying levels of difficulty. Therefore, the development of the CT-LiWa test can be implemented as an instruent to measure students' critical thinking skills on the concept of light waves.

Abstract

Student Worksheet (LKPD) is a learning tool that has a role in activating students in the learning process. This training aims to introduce technology that can support practicum as an optimization of the implementation of Physics practicum activities by utilizing the Physics Toolbox Sensor Suite application. The methods used in this activity include socialization, lectures, and discussions. Participants in this activity were Physics teachers totaling 46 people. This activity was conducted in three meetings. Participants received an introduction to the various features of the Physics Toolbox Sensor Suite application at the first meeting. Expert lecturers guided the trainees in the application of the tool in the second meeting. After receiving guidance, the trainees were directed to make the LKPD which would then be presented at the third meeting. This training produced six LKPDs with six different Physics materials. The results of the LKPD assessment by experts showed a very positive view of the quality of the LKPD. LKPD generated in this training is considered to have fulfilled all indicators of Science Process Skills (KPS). Through this activity, it can be concluded that the KPS-based LKPD assisted by the Physics Toolbox Sensor Suite application can be a practicum tool that facilitates the implementation of Physics practicum in schools that do not have or lack practicum tools. It is recommended that the use of laboratories and virtual laboratories can be conducted continuously to support Physics learning.
