Abstract

Learning loss is when a student loses academic knowledge and skills due to certain situations and conditions, such as pandemics, long school holidays, and other emergencies. An effort can be made to determine the learning loss that occurs in students by using diagnostic tests. However, the availability of questions for diagnostic tests on mathematics, especially trigonometry material, is still limited. This research aims to develop and validate diagnostic test questions to measure high school students' learning loss in the trigonometric function topic. This research uses preliminary research in the development stage with the Plomp model. The stages carried out in this study include self-evaluation and expert review. Document analysis is carried out at the self-evaluation stage by identifying basic competencies and formulating indicators, compiling a learning continuum, formulating attributes, compiling a Q matrix, and constructing questions. Then, three validators tested the validity and feasibility of the questions. The results of the validity test show that the 25 diagnostic questions that have been developed all meet the very valid criteria, with the average score for each item from the three validators being more than 3.20.

Abstract

The Covid-19 pandemic has opened the gates to digital learning in mathematics education and increased the use of online learning. However, teachers still rare to use digital technology as feedback and final evaluation of students. Therefore, an e-learning based remedial video is needed to developed. The research aims to produce e-learning based remedial videos on fraction that meet the criteria of valid, practical and effective. This research is development research with ADDIE models namely analysis, design, development, implementation, and evaluation. The subjects of this research were class 8 students at junior high school from three school levels in Banda Aceh, Indonesia. Data was collected using video validation sheets, students’ response questionnaires, and remedial tests. The results show that e-learning based remedial videos was valid based on expert judgements, practical because students gave positive responses and effective because N-Gain of the percentage of students reached the Minimum Completeness Criteria (MCC) on diagnostic test and remedial test was 0.5 on the medium category.

Abstract

This study aims to determine the comparison of the mathematical communication skill of students of class VIII SMP who are taught through the Quantum Learning model. Mathematical communication skills are still low due to the inability of students to channel their ideas systematically. The research method used was experimental research with a pretest-posttest control group design. The population in this study were all students of class VIII SMP Negeri 4 Langsa. Sampling was carried out using the Simple Random Sampling technique and obtained two classes, namely class VIII-5 as the experimental class and VIII-6 as the control class. Data collection was used by using a mathematical communication ability test sheet. From the research results obtained  and , then   means it can be concluded that the average mathematical communication skill of students who learned with Quantum Learning Model is better than the average mathematical communication skill of students who are taught using conventional learning.model.
