Abstract

This study aims to compare the mean problem-solving ability of students treated with the problem-based learning with discovery learning on the SPLDV material. The population in this study were all students of class VIII SMPN 4 Takengon. Sampling using cluster random sampling selected classes VIII2 and VIII3. Data collection techniques using tests and observations. The research instrument used a problem-solving ability test and observation sheet. The data analysis technique uses the t-test which is used to compare problem-based learning with discovery learning. Based on the research results, it was found that the mean problem-solving ability treated with the problem-based learning model was higher than that given the discovery learning treatment. The difference in the mean problem-solving ability between the problem-based learning and discovery learning classes is caused by the different treatment given to the two classes.

Abstract

This study aims to utilize GeoGebra electronic teaching materials to create a learning path in understanding statistical material. Design Research is used as a research method that can formulate and describe theories in statistical learning. The learning was designed at an early stage and tested on 24 students of XI Grade at SMK Baiturrahim. The results obtained in this study are a learning trajectory consisting of 3 activities, activity 1; data presentation, activity 2; data centering, and activity 3; statistical questions. From the resulting activities, it can be concluded that learning with GeoGebra-assisted electronic teaching materials can increase students' learning motivation and increase students' interest in learning mathematics, especially statistical material.

Abstract

This research is a research on the development of teaching materials based on e-learning. This study aims to produce Student Worksheets (LKS) on .-based Two Variable Linear Equation System (SPLDV) material e-learning. The research method used in this research is research and development (R&D) methods. This research is only up to the produce products that are tested for validity and practicality. Study This development adapts the 4D (four-D) development model. This research was conducted through four main stages, namely (1) defining (define) the goal is to find out the initial needs in developing LKS such as, learning objectives and competencies achieved. (2) The design is the stage of making the LKS draft. (3) Development (develop) is a product test that is validated by 7 validator. (4) Dissemination is the distribution of worksheets that have been developed. The results of the LKS validation are: (1) the validator assesses it is feasible with a percentage of (80.31). (2) respondents rated practical with percentage of (77.46). Based on these results, the LKS that has developed feasible and practical to use.

Abstract

Instagram Reel is one of the social media currently popular, but it has not been widely used to create mathematics learning media. This research aims: (1) to develop a learning Instagram Reel for the subject of linear Equations for Junior High School and (2) to find out from the Instagram Reel developed in this study. The research method used is Research and Development (R & R&D) with the ADDIE model, consisting of 5 stages: Analysis, Design, Development, Implementation, and Evaluation. The research subjects were 22 students of SMP Negeri 3 Bantul. The result of this research is Instagram Reels learning for the subject of linear Equations for Junior High School, presented through the Instagram account @mathematics_fun. This Instagram reel was declared suitable for use because the average total validation score for aspects was 4.61 (including the very valid category), and the average student response questionnaire score was 3.91 (including the good category). The implication is that teachers are advised to use Instagram Reels as a learning medium. It is recommended that teachers develop Instagram for other materials.

Abstract

This research is a learning media development research that aims to produce an online snake and ladder learning media "Interactive Mathematics Path" on the Bangun Datar material using an ethnomathematical approach. The method used in this study is the Research and Development (R&D) method by adapting the 4D (four-D) development model. However, at the implementation stage, this research only reached the development stage by producing products that have been tested for validity and practicality. This research was conducted through four stages, namely (1) Defining, by analyzing the needs in learning, such as problem analysis, student analysis, concept analysis and analysis of learning objectives. (2) Design, by making prototypes (initial drafts of learning media) and research instruments. (3) Developing, by testing the product by validators and by students on a limited basis, then making improvements. The results of the validation of the learning media "Interactive Mathematics Path" are feasible with a slight revision and the percentage is 91.1%. The results of the limited trial show that the product of practice is used in learning with an average percentage of 88.4%.

Abstract

This research is descriptive qualitative research. The purpose of this study is to find out what difficulties are experienced by junior high school mathematics teachers in implementing online learning and solutions that can be applied to reduce these difficulties. This research was conducted at SMP Negeri 1 Lendah. The data sources are 4 mathematics teachers of SMP Negeri 1 Lendah. Data was collected by means of observation, interviews, and documentation.  The results showed that the difficulties of mathematics teachers in implementing online learning during the COVID-19 pandemic were the lack of understanding of IT, low student activity, insufficient cellphone ownership and unsupportive signals. In addition, solutions that can be done to reduce these difficulties include increasing teacher insight in the IT field, limited face-to-face learning and collaboration of all school members, teachers and students. Suggestions from this research are teachers must improve IT skills, schools must cooperate with parents, students must increase activeness in learning and researchers can use this research as a reference in research related to the effectiveness of online learning.
