Abstract

This study aims to compare mathematical problem-solving ability among learners who learned with problem-based learning model (PBL) and problem-solving. The study also aims to determine the thinking process of learners in the problem-solving. The study was using an experimental method. The population was all students of class VIII SMP Negeri 13 Kota Tasikmalaya. The samples were selected two classes by cluster random sampling, first class (VIII-E) was learned by using PBL model and second class (VIII-J) was learned by using problem-solving. Data collection techniques use mathematical problem-solving tests. The data were analyzed by t-test of two difference means. The study concludes that the mathematical problem-solving ability of learners who learned with PBL model better than that learned with a problem-solving model. The conceptual thinking process in the PBL class was owned by high-ability learners, while in the problem-solving class was owned by high and middle-ability learners. The semi-conceptual thinking process of the PBL class was owned by moderate and low-ability learners, while the problem-solving class was owned by moderate-ability learners. Computational thinking processes in PBL classes and problem-solving one were owned by low-ability learners.Keywords: problem-based learning (PBL), problem-solving, mathematical problem-solving ability, thinking process.

Abstract

The study aims to analyze the difficulties of teachers in authentic assessment of mathematics during the pandemic. Authentic assessment includes knowledge assessment, attitude assessment, and skills assessment. This study used a qualitative research with a descriptive design. The sample of this research is 100 mathematic teachers in Tasikmalaya City. Data collection techniques in this study by questionnaires. Analyzed using the concept of Miles and Huberman through reduction, data display and conclusion. The results showed that the difficulties of authentic assessment in mathematics learning include requiring intensive time, making assessment impractical, difficulties in developing teaching materials, and difficulties in planning the type of assessment.

Abstract

This research aims to develop an E-LKPD integrated with FlippingBook technology based on the Environmath approach, as well as to investigate the enhancement of students’ metaphorical thinking skills before and after the implementation of the developed instructional materials. The study utilized a Research and Development (R&D) methodology guided by the ADDIE model, which comprises five sequential phases: analysis, design, development, implementation, and evaluation. Data were gathered through observations, expert validations of both material and media aspects, and assessments of students’ metaphorical thinking abilities. The participants involved in this study included two material experts, three media experts, and twenty seventh-grade students from MTs Miftahul Falah Panumbangan. The findings revealed that during the analysis stage, a needs analysis, student analysis, and material analysis were conducted. In the design stage, test instruments were prepared, media and format were selected, and the initial product design was developed. The development stage includes the product development process, while at the implementation stage, E-LKPD was tested on students. Furthermore, at the evaluation stage, it was found that there was a significant increase in metaphorical thinking skills after students used E-LKPD assisted by FlippingBook based on environmath with the quality of the increase being in the high category.
