Abstract

Problem-solving ability is one of the essential learning characteristics in 21st-century skills, which requires students to think critically during the problem-solving process. Thus, the purpose of this study was to describe students' problem-solving skills in HLT-based RME learning. This research used a qualitative method with a case study design. The research was implemented in SMP Negeri 3 Satu Atap Tawangharjo. The research subjects were the principal, math subject teacher, and seventh-grade students. Data validity used triangulation of methods and sources. Data analysis technique with flow method. The results showed that some students had high, medium, and low mathematical problem-solving abilities in solving math problems. In conclusion, students' problem-solving ability in HLT-based RME learning has a high percentage. The percentage of students with high problem-solving ability is 75%, those with moderate problem-solving ability make up 15%, and those with low problem-solving ability account for 10%. Thus, students who were able to solve problems in HLT-based RME learning were more than students who were not able to solve problems in HLT-based RME learning.

Abstract

Assessment of learning outcomes is an essential aspect in the learning process to measure students' competency achievement. This study aims to analyze the quality of summative assessment questions at the end of the even semester in Mathematics at Madrasah Ibtidaiyah (MI). The analysis was carried out on five main aspects: validity, reliability, level of difficulty, discriminatory power, and distractor effectiveness. The study used a descriptive quantitative approach with data obtained from question documents, answer keys, and answer sheets of grade V students (n = 26). Data analysis techniques included point biserial correlation for validity testing, Cronbach's Alpha for reliability, and classical formulas for level of difficulty, discriminatory power, and distractor effectiveness. The results showed that 64% of the questions were valid, the reliability of the questions was quite high (α = 0.78), 40% of the questions were categorized as moderate difficulty, and 60% had good to very good discriminatory power. However, there were 36% of questions that were invalid and some distractors did not function optimally. These findings indicate that the quality of the questions is generally quite good, but revisions need to be made to less than optimal question items to improve the effectiveness of the assessment.
