Abstract

In order to create the next generation of people with character, religious values really need to be instilled in students. One of them is by integrating religious values in learning material. Integrating this aspect can show positive changes to face global competition in the era of 4.0. This study aims to develop a questionnaire instrument for measuring the religious character of students integrated in chemistry learning. The research design used is R & D (Research and Development) research. The development model used is a modified 4-D model as suggested by Thiagarajan, Semmel and Semmel which consists of define, design, develop and disseminate. Based on the results of this study, it can be concluded that this study produced a questionnaire instrument for measuring students' character in chemistry learning consisting of 20 indicators that were declared valid and reliable with a validity price of 0.9028 and a reliability of 0.9037. The questionnaire instrument was developed by integrating religious character values with the learning of hydrocarbon chemistry. The results showed that the questionnaire instrument was effective for measuring the religious character of students with an average increase in the religious character of students by 0.54 so that it was included in the medium category.

Abstract

The 21st century demands that students develop various skills, including critical thinking. This study investigates how effective an interactive video-assisted Problem-Based Learning (PBL) model is in enhancing students' critical thinking skills on the topic of atomic structure and the benefits of nanomaterials. The research used a quasi-experimental design with non-equivalent control groups. The sample was selected using cluster random sampling, with class X4 as the experimental group and class X6 as the control group. Data were collected through pre-tests and post-tests, which were analyzed using the product-moment correlation formula to validate the test instruments. The results showed that the experimental group's average post-test score for critical thinking skills was 75.944, higher than the control group's score of 61.278. The hypothesis test using an independent sample t-test revealed a Sig (2-tailed) value of 0.000, which is less than 0.05, indicating that the alternative hypothesis (Ha) is accepted and the null hypothesis (H0) is rejected. Additionally, the effectiveness of the model was assessed using the n-gain test, resulting in a mean value of 0.6327, which falls into the medium effectiveness category.
