Abstract

Learning tools play an important role in supporting the achievement of learning objectives. However, the use of printed textbooks in the learning process is still not optimal, and the student worksheets (LKPD) used do not fully meet the criteria for ideal worksheets. In addition, the current worksheets have not been designed to develop students' critical thinking skills. To address these problems, this study aims to develop an interactive E-LKPD based on a Problem Based Learning (PBL) approach that is valid and practical in improving critical thinking skills. This research is a development research by applying the 4D model consisting of four main stages, namely defining (defining), designing (designing), developing (developing), and disseminating (disseminating), although the dissemination stage was not implemented in this study. In the definition stage, an analysis of the characteristics and needs of students was conducted. The design stage includes designing the structure of the content and appearance of the E-LKPD, while the development stage includes a validity test by two expert lecturers and one science teacher. Based on the validation results from the experts, the interactive E-LKPD with a PBL approach obtained a validity assessment percentage of 91,2%, which is included in the highly valid category. Thus, it can be concluded that the developed interactive e-LKPD has proven to be highly valid and practical for use as an innovative learning medium that supports students' critical thinking skills.

Abstract

Critical thinking is a 21st-century skill that is crucial for problem-solving and decision-making. However, the learning process in schools is still not optimal in developing this skill. This study aims to test the validity of an e-module product developed to improve critical thinking skills. This research is a developmental study using the 4D model. The instrument used was an expert validation sheet. Data collection was carried out through a questionnaire in the form of a validation sheet given to the validators. Data were analyzed quantitatively based on the validation results, then elaborated with qualitative analysis. The results showed that the material validity value from the three validators was 88.47%, language validity was 89.33%, and media validity was 87.33%. These three results were then averaged, resulting in an overall validity value of 88.37%, which is categorized as valid. Input from the three validators was used as a reference for improving the e-module. Thus, it can be concluded that the e-module on the human respiratory system based on problem-based learning to improve critical thinking skills is valid and worthy of being tested.
