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.

Abstract

The 21st century is characterized by the use of technology, information and communication in various fields of life, one of which is education which is applied in the learning process. Based on observations at MA NU Miftahul Ulum Margasari, it is known that the available and frequently used learning media are in the form of textbooks, worksheets, videos, powerpoints, and audio. This causes the ongoing learning process to appear less attractive to students, thus making students feel bored and have less interest in learning chemistry which has an impact on a passive classroom atmosphere. The purpose of this research is to develop iSpring suite 9 interactive learning media based on android on redox material. The type of research used is development (Development Research) with the Plomp development model. The results showed that the percentage of eligibility based on 4 validators obtained an average value of 81.075% from the appearance aspect, 85% from the feasibility aspect, and 82.475% from the programming aspect. Based on the percentage obtained, it proves that the android-based iSpring Suite 9 learning media is very feasible to try out on students.
