Abstract

Despite a long tradition of harvesting nyale in southern coast of Lombok island teacher’s understanding on the animal producing nyale are very low. This study aimed to develop a learning module of nyale worm biology for teachers and students. The developmental research method was adapted from the Borg and Gall model which includes 10 steps. Data on module feasibility were collected through a process of validation of the learning module. Questionnaires on the student’s and teacher’s responses to the learning module were administered to assess module practicability. The data were analyzed using descriptive statistics. The results showed that the feasibility of the subject material was 85.90%, the media feasibility was 81.71%, and the user test was 81.09%. The learning module of nyale worm biology is very valid, effective, and practical as a supporting book for learning biology at high schools

Abstract

The research was carried out with the aim of knowing the effectiveness of the video-assisted scientific approach on students' critical thinking skills. The study used a quasi-experimental method. The research was carried out on high school students in the city of Mataram with a total sample of 323 as the research sample. Data Inferential analysis with Analysis of Covariance (ANACOVA) followed by Least Significance Difference (LSD), was used to test the research hypothesis. The results showed that the learning approach had a significant effect on learning activities with an F hit value of 60.37. The scientific approach is not significantly different from the video-assisted scientific approach, but is significantly different from the conventional approach with a mean value of 62.17 for video-assisted scientific approaches and an average of 64.69 and a conventional approach of 47.48. The video-assisted scientific approach improves students' critical thinking skills.

Abstract

The low level of scientific literacy and critical thinking skills of students demands the development of contextual teaching materials that are in accordance with the demands of 21st-century learning. This study aims to develop science teaching materials with a Project Based Learning model integrated with STEM that is feasible, practical, and effective to improve students' scientific literacy and critical thinking skills. This study is development research using the 4D model (Define, Design, Develop, Disseminate). The trial subjects consisted of 42 eighth-grade junior high school students selected through convenience sampling techniques. The feasibility test was carried out through expert validation, practicality through observation of learning implementation and teacher and student response questionnaires, while effectiveness was analyzed using N-gain. The results showed that the developed teaching materials had a very high level of validity with a value of 0.914 and a percentage of agreement of 94.30%. The practicality of the teaching materials was also classified as very high, indicated by the learning implementation of 93.75%, teacher responses above 96%, and student responses above 90%. In addition, the teaching materials were proven to be effective in improving scientific literacy (N-gain 0.79) and critical thinking skills (N-gain 0.76) in the high category. Thus, science teaching materials with the STEM-integrated PjBL model are feasible, practical, and effective in improving students' scientific literacy and critical thinking skills, and can be used as an innovative alternative in science learning.
