Abstract

Abstract This research aims to determine the results of the implementation of Video Explainer in terms of students' Problem Solving Ability. This research is Classroom Action Research which consists of 2 cycles, each cycle consisting of 2 meetings. The data collection technique is through giving a problem solving ability test. The subjects in this research were 28 students of class IX SMP Negeri 1 Sinunukan. The results of the students' problem solving ability test in the initial test showed that 5 students (17.85%) experienced completeness with an average ability test score of 54.82 in the very low problem solving ability category. In the first cycle, there was a classical improvement as shown by the achievement of 13 students (46.42%) completing the test with an average score of 66.78 in the low category. Implementation continued in cycle II, student test results experienced a classical increase, 25 students (89.28%) completed the results with an average score of 80.23 in the high category. From the results of the tests given, there was an increase from the initial test to cycle II. Thus, it is concluded that implementing explainer videos can improve the problem solving abilities of class IX students at SMP Negeri 1 Sinunukan.

Abstract

This study aims to analyze the mathematical problem-solving abilities of 25 eleventh-gradestudents at SMA Negeri 1 Barumun Tengah in solving Higher Order Thinking Skills (HOTS)questions related to arithmetic and geometric sequences. The research employed a descriptivequalitative approach with data collected through written tests, interviews, and observations. Thefindings indicate that most students struggled to solve HOTS questions systematically. Based onPolya’s problem-solving steps, 80% of students were able to understand the problem, 60% coulddevise a strategy, 52% were able to carry out the strategy, and only 36% evaluated their resultsindependently. The greatest difficulties were found in the planning and evaluation stages, primarilydue to low critical thinking skills, lack of exposure to contextual questions, and the dominance ofprocedural-based teaching. These findings highlight the importance of systematically integratingHOTS questions into mathematics instruction to foster students’ higher-order thinking skills.

Abstract

This study aims to evaluate the effectiveness of integrating GeoGebra in mathematicsinstruction through a Problem-Based Learning (PBL) model supported by the TechnologicalPedagogical Content Knowledge (TPACK) framework in teaching three-dimensional geometry. Theresearch subjects consisted of 30 twelfth-grade science students and three mathematics teachersfrom SMA Negeri 1 Sihapas Barumun, while the object of the study was the implementation processof GeoGebra-assisted learning. A mixed-methods approach with an explanatory sequential designwas employed, combining quantitative data (tests and attitude questionnaires) and qualitative data(observations and structured interviews). The results revealed a significant improvement in students'conceptual understanding, with average test scores increasing from 78.5 to 87.2. Additionally, therewas a positive shift in students' affective responses, including enhanced motivation and selfconfidence, as well as increased technical and collaborative skills. In conclusion, the integration ofGeoGebra within the PBL-TPACK framework effectively enhances spatial reasoning, learningengagement, and 21st-century skills in mathematics education.

Abstract

The development of digital technology has significantly transformed the field of education, particularly at thesenior high school level. On one hand, technology offers great potential to enhance student learning motivationthrough broad access to information, interactive media, and flexible learning schedules. On the other hand,digital disruption also presents challenges such as social media distractions, visual fatigue, and unequalaccess to technology. This study aims to identify the factors that influence students’ learning motivation in thedigital era and formulate strategies to optimize the use of technology in education. Employing a descriptivequantitative approach, a survey was conducted involving 72 science-track students at SMA Negeri 1 PadangBolak. The ARCS model (Attention, Relevance, Confidence, Satisfaction) served as the analytical frameworkto assess student motivation. The results show that 70.8% of students reported increased motivation with theaid of digital technology, especially in the areas of attention and satisfaction. However, 55.5% admitted beingdistracted by social media, while 48.6% experienced fatigue due to prolonged screen exposure. The studyrecommends the integration of technology-based pedagogy, the strengthening of digital literacy, andproportional supervision of digital device use to foster effective, meaningful, and motivating learningexperiences

Abstract

This study aims to describe the profile of pattern generalization strategy (SGP) in functional thinking of secondary school students. The profile of SGP in functional thinking of secondary school students in this study is a differentiator in revealing students' pattern generalization strategies in functional thinking in more detail. A qualitative approach was used in this study. Data collection was conducted on 220 students of MTsN 2 Padangsidimpuan. Qualitative analysis from Miles, Huberman & Saldana was conducted to analyze algebra assignments and student interview results. The results showed that students' SGP included arithmetic pattern generalization, factual pattern generalization, contextual pattern generalization, and symbolic pattern generalization. High ability students perform symbolic and contextual pattern generalization activities. Medium ability students generalize factual and contextual patterns, and low ability students generalize factual and arithmetic patterns. The contribution of this research is helping students understand the concept of functional material better, increasing students' generalization abilities, developing students' abstract thinking skills and helping teachers in designing learning methods.

Abstract

This research aims to develop a discrete mathematics module based on discovery learning to improve students’ mathematical understanding in higher education. This research used the Research and Development (R&D) method with a mixed approach and ADDIE model in the product development stage. The data collection techniques used questionnaires, tests and interview guides. Meanwhile, the data analysis technique used in this research combines qualitative and quantitative descriptive. The results include (1) Reviewing the study of discrete mathematics module development; it obtained valid results after going through several assessments and revisions, and the practicality of developing this discrete mathematics module was categorized as practical; it is not surprising that the module can increase students’ mathematical understanding with a range of 37.97; (2) Judging from effectiveness; it is obtained from inferential statistics that significance is 0.00, which means there is an influence on the use of discovery learning-based discrete mathematics modules on students’ mathematical understanding. These results have implications that the module has proved effective in improving students’ mathematical understanding in higher education.
