Abstract

A good instrument is an instrument that can measure students' abilities accurately. The research aims to analyze the quality of critical thinking and creativity items on water pollution material in terms of validity, reliability, and level of difficulty using the Rasch model. The research used a quantitative descriptive method involving biology learning experts and 173 class X high school students. The research was carried out in December 2023-January 2024. The data collection method used expert assessment sheets and critical thinking and creativity essay questions. Data were analyzed using the Rasch model assisted by Quest. The results showed that of the 10 critical thinking essay questions, 3 questions were invalid, while of the 8 creativity essay questions, 1 question was invalid based on the suitability of the INFIT MNSQ and OUTFIT T scores. The results of the reliability test with Cronbach’s alpha showed that the reliability value of the critical thinking instrument was 0.74 and creativity 0.79. Average difficulty level of questions with threshold values in the medium and difficult categories. Overall, the instrument was feasible and question items that did not fit the Rasch model were removed.

Abstract

Worksheets are still often made in the format of questions that are done individually. Kombucha, when viewed from the characteristics of the manufacturing process, have the potential to be innovations in conventional biology technology innovation learning. This study aimed to assess the feasibility and practicality of using project-based learning electronic worksheets with kombucha bioprocess for teaching biology. The research method employed was development research using the ADDIE model, focusing on the analysis, design, and development stages. The study involved one material expert, one media expert, two biology teachers, and 33 students. Data was collected using interviews and questionnaires. The electronic worksheet was evaluated by media and material expert lecturers for feasibility and by teachers and students for practicality The results indicated that this worksheet is both feasible and practical for biology learning activities with a material validity level of 72.6% (feasible), media validity of 98% (very feasible), biology teacher response 92% (very practical) and student response 85% (very practical). The findings of this study are expected to be an inspiration for educators in compiling media for learning activities, becoming the latest and most interesting learning content innovations in project creation.
