Abstract

This research aims to describe a comprehensive learning process on how technology, pedagogy and content knowledge are integrated in the learning process. An observational qualitative study was used to conduct the research involving 35 students and 1 mathematics teacher in a senior high school in West Java. The results showed that from the aspect of Pedagogical Knowledge (PK), the teacher showed a good ability in conveying derivative concepts with varied methods. In terms of Content Knowledge (CK), teachers have a good and in-depth understanding of the derivative material of algebraic functions and are able to answer student questions clearly and provide relevant examples. In terms of Technological Knowledge (TK), the use of technology both low tech (markers and blackboard) and digital technology (WhatsApp) shows how technology can be used to facilitate learning. Overall, this observation shows that good integration of pedagogical, content and technological knowledge can improve learning effectiveness and students' understanding of the concept of algebraic function derivative.

Abstract

Critical thinking skills are crucial for students to analyze and solve problems effectively, yet many still struggle in apply them comprehensively. This study aimed to examine students' critical thinking skills using a qualitative descriptive approach. The study used an essay-based assessment developed based on the framework of Perkins and Susilo et al., which includes four main indicators: clarification, judgment, inference, and strategy development. The findings indicated that students demonstrated partial critical thinking skills; most could analyze or clarify problems, while some could present problems with reasoning or examples and draw compelling conclusions. However, many students still struggled to develop effective problem-solving strategies. These results imply the need for improved instruction that places greater emphasis on strengthening problem-solving skills to enhance students' overall critical thinking skills.
