Abstract

This study examined the low mathematical problem-solving ability of grade VIII students at SMP N 13 Merangin, where only 12 out of 35 students achieved the Minimum Completeness Criteria (KKM), far below the classic achievement target of 70%. In addition, student learning outcomes are still relatively low at 31.18%, completely because the learning method is still centered on teachers. This study aims to describe the mathematical problem-solving ability of students using the Thinking Aloud Pair Problem Solving (TAPPS) learning model better than conventional learning. An experimental method was used, with 124 grade VIII students as the population and simple random sampling to determine class VIII B as the control group and VIII C as the experimental group. Data was collected using essay questions on algebraic simplification. The normality test using the Kolmogorov-Smirnov formula and the homogeneity test with the Hartly test (F-test) showed normal and homogeneous distributed data. The hypothesis test using the t-test produces a calculation value of t-calculate. =2.65 is greater than, =1.67, meaning,  Accepted. This shows that the mathematical problem-solving ability taught using the TAPPS model is better than the conventional method.

Abstract

This study aims to examine the application of the ethnochemistry approach in chemistry learning through the integration of betel chewing culture in functional group material using a scientific approach. The betel chewing culture involving materials such as betel leaves (Piper betle), areca nut (Areca catechu), and betel lime (calcium hydroxide) is known to contain various active chemical compounds, including alkaloids, phenols, esters, and alcohols. The scientific approach allows students to observe, ask, try, reason, and communicate the results of the analysis of these materials, so that they can understand the concept of functional groups in the context of local culture. This study uses a descriptive qualitative method with a literature study approach and participatory observation of the practice of betel chewing culture in the community. The results of the study show that the integration of local culture in chemistry learning can improve students' conceptual understanding, learning interest, and cultural awareness. The ethnochemistry approach has proven effective in creating contextual, meaningful, and relevant learning to students' daily lives. Therefore, the application of a local culture-based learning model through a scientific approach is recommended as an innovative alternative in chemistry learning. Keywords: Ethnichemistry, betel chewing culture, scientific approach, functional groups, contextual chemistry learning.
