Abstract

This research is motivated by the use of learning media that is not in accordance with the characteristics of students, where currently in the learning process educators only use textbooks and LKPD. Educators lack innovation to develop learning media that are more modern and in accordance with the characteristics of students, such as developing media that uses the internet and digital technology as operating tools. Based on this, research was conducted on the development of mathematical e-comic media based on Contextual Teaching and Learning on social arithmetic material for class VII students who met the valid, practical, and effective criteria. The research method used is Research and Development (R&D) with the ADDIE model (Analysis, Design, Development, Implementation, Evaluation). This study involved 7th-grade students of SMPN 1 Sintuk Toboh Gadang, 6 students were selected as the subject of the one-to-one evaluation and 12 as the small group trial. This research produces a valid, practical, and effective mathematical e-comic based on Contextual Teaching and Learning media. The results of this study indicate that the e-comic media meets the very valid criteria with an average validity of 88.05%, meets the very practical criteria with average practicality of 92.36% for educators and 90.02% for students, meets the effective criteria with acquisition of a complete percentage of 83.33 %.

Abstract

Education always strives to create students who always make updates for the sake of updates all the time. Not only able to be highly educated but able to be an agent of change in small and large scopes. The resulting changes and innovations are able to provide maximum contribution to the progress of a nation that has quality human resources. This research aims to find out how the Independent Learning curriculum concept is implemented, especially in mathematics subjects at MAN 1 Padang. The method used is a qualitative research method using literature study. From the research conducted, MAN 1 Padang is a school that is still implementing the 2013 curriculum in the 2022/2023 academic year. Meanwhile, for the Merdeka Belajar curriculum, the Merdeka Belajar curriculum has already been introduced, but it is still in broad outline. Meanwhile, the implementation of the independent learning curriculum will only begin to be implemented in the new academic year 2023/2024.

Abstract

The mathematical problem solving ability of students at Universitas Islam Negeri Sjech Djamil Jambek Bukittingi is still relatively low. The flipped classroom learning model assisted by YouTube is one of the solutions. The purpose of this study was to determine the difference in mathematical problem solving ability of students who learn with the flipped classroom learning model assisted by YouTube and the mathematical problem solving ability of students who learn with conventional learning. This research is a type of pseudo-experimental research with a randomized control group only design. The population of this study were students of the Islamic economics study program at the State Islamic University Sjech M. Djamil Djambek Bukit Tinggi with Islamic economics class C as the experimental class and Islamic economics D as the control class. The number of students from each class is 30 people. The instrument used is a test of mathematical problem solving ability. From the research results, the average mathematical problem solving ability of students in the experimental class was 78.47 while the control class was 68.73. The analysis results of the classical assumption test showed that the students' mathematical problem solving ability was normally distributed and had a homogeneous variance. Testing with independent sample t-test results in the value of t count (3.130) t table (2.002) and sig value (0.003) 0.05. The results of this test explain that there is a significant difference in mathematical problem solving ability in the experimental class using the flipped classroom learning method assisted by YouTube with the control class using conventional learning. Based on the findings of this study, it is recommended for lecturers to have their own YouTube channel that helps them to deliver lecture material, so that it can be accessed and used at any time by students.

Abstract

Errors in solving math story problems remain a common problem among students. This is due to the lack of in-depth analysis by teachers of the types of errors made by students based on Kastolan's theory, resulting in the same patterns of errors being repeated. Based on this problem, this study aims to identify and describe the types of errors made by students in solving mathematical story problems based on Kastolan's theory. This study uses a quantitative descriptive approach with a sample of 36 students in class X.E6 at SMAN 2 Bukittinggi, selected through purposive sampling. The research instrument was a story problem test on trigonometry consisting of five questions. The data were analyzed using descriptive statistics to obtain the percentage of each type of error. The results showed that 21 students (59.44%) made conceptual errors, 24 students (67.67%) made procedural errors, and 22 students (62.78%) made technical errors. Thus, procedural errors were the most dominant type of error made by students. These findings indicate the need for more systematic learning strategies and an emphasis on procedural understanding in solving mathematical story problems.
