Abstract

The Merdeka Curriculum focuses on basic material, character development and competency. The independent curriculum provides the opportunity for classes XI and XII to choose subjects according to their preferred interests. Based on interviews and observations conducted at SMAN 14 Semarang, it is known that chemistry is the least popular subject because it is the first subject with the lowest number of voters. Therefore, efforts that can increase student interest need to be made. The aim of this research is to conduct an analysis of the efforts made to increase students' interest in learning chemistry. The method used in this research is descriptive qualitative. The research results show that innovative and creative teachers have an impact on students' interest in learning chemistry. innovative and creative teachers can use various creative ideas in learning, such as choosing learning approaches, learning media, and creating a pleasant classroom atmosphere.

Abstract

The teaching of factors affecting reaction rates in high schools still tends to emphasize conceptual aspects and does not fully relate chemical concepts to real-life contexts. This condition prevents students' creative thinking skills and entrepreneurial interests from developing optimally. Therefore, digital teaching materials that can facilitate active, contextual, and meaningful learning are needed. This study aims to develop and test the feasibility and effectiveness of Chemoentrepreneurship-oriented Project-Based Learning Electronic Student Worksheets on the subject of factors affecting reaction rates in improving students' creative thinking skills and entrepreneurial interest. This study used a research and development method with a Four-D model, which includes the stages of definition, design, development, and dissemination. The research subjects were grade XI students at a public high school, who were divided into an experimental class and a control class. Data were collected through expert validation sheets, pre-tests and post-tests, creative thinking ability observation sheets, and entrepreneurial interest questionnaires, then analyzed descriptively and inferentially. The results showed that the developed Electronic Student Worksheets met the criteria of being highly feasible based on expert validation. In addition, it has been proven that the use of these teaching materials can improve students'.

Abstract

Critical thinking skills are essential for chemistry pre-service teachers, particularly in pre-laboratory sessions. However, many students struggle to apply these skills before conducting experiments. This study aims to analyze the critical thinking profile of chemistry pre-service teachers in pre-laboratory sessions, identifying key indicators that require improvement. This research adopts a quantitative descriptive approach with purposive sampling, involving 32 second-semester Chemistry Education students enrolled in the Basic Chemistry Practicum course. The research instrument consists of 40 multiple-choice questions based on Ennis' critical thinking indicators. Data were collected through pre-laboratory tests and analyzed using descriptive statistics to determine score distribution and categorize students' critical thinking levels. Results show that most students fall into the fairly good category (62.50%), while 15.62% reached the good category. The highest-scoring indicator was defining terms (81.250, good category), while analyzing arguments had the lowest score (48.125, less category). These findings indicate that students struggle with evaluating information and connecting theories to experimental outcomes. This study provides a specific analysis of critical thinking skills in pre-laboratory sessions, an area that remains underexplored. The findings support the need for inquiry-based learning, reflective discussions, and scientific argument evaluation to enhance critical thinking skills in chemistry pre-service teachers.
