Development of HOTS (higher order thinking skills) test instruments for the concept of fluid and harmonic vibrations for high schools

Abstract

The thinking ability of Indonesian students is still relatively low, this can be seen from the ranking of Indonesia based on the results of TIMSS in 2015. To improve students 'thinking abilities and provide reinforcement to students' abilities, one of the efforts is to equip students with higher-order thinking skills by using questions HOTS is based on the Borg and Gall development model. A Higher Order Thinking Skill (HOTS) instrument has been developed that is subject to a valid and reliable fluid subject in high school using the Borg and Gall development model. This study aims to: 1) produce HOTS physics questions based on a valid and reliable Borg and Gall development model. The trial was carried out in SMAN 3 Palembang with class X MIA 1 students as research subjects. The data collection instruments used consisted of questions grids, question sheets, and validation sheets. The data analysis technique used is item analysis consisting of validity, difficulty level, and different power analysis, and reliability testing. The results of this development are 15 valid questions out of 25 items created. Of the 25 items, 3 items were declared difficult, 20 items had a moderate level of difficulty, and 2 other items were relatively easy. In addition, these questions are also stated to be reliable with a Cornbach's Alpha value of 0.78. The results of this study indicate (1) data collection as a validation test with an expert lecturer of 4.5 which is very valid. (2) a reliable test in the initial field test stage obtained an average score of the reliability of stages one and two respectively 0.74 and 0.76 with a high level of reliability. Thus, based on the results of the research data it was found that the instrument about HOTS fluid material developed was classified as valid and reliable.
