Abstract

The research conducted was classroom action research to improve the learning outcomes of students of class XI MIPA 6 Senior High School 2 Palembang. Improved learning outcomes are carried out by using the discovery learning model during the learning process. As for this research, using a subject consisting of 35 students. The subject used by researchers in this study is the formula of the sum and difference of sine, cosine, and tangent of two angles. In the first cycle consisted of 3 meetings and Cycle II consisted of 2 meetings. This study uses instruments in the form of test results of learning and observation. Tests of learning outcomes are used by researchers as a way to find out the achievements of students from each cycle and observations are used by researchers to collect data during the learning process takes place. Quantitative and descriptive data analysis was used in this study. Based on the results of the study, it was found that the average value of students of class XI MIPA 6 on the first cycle test was 63.00 and increased on the second cycle test to 83.69. The results of this study indicate that learning using the discovery learning model can improve students' mathematics learning outcomes, i.e. 74.28%  of students have achieved indicators of success in the second cycle of research.

Abstract

Abstract. This study aims to develop and assess the feasibility of learning videos, created with the Canva application, for matrix multiplication material for eleventh-grade senior high school students. The study employed a development research method using a development model combined with Tessmer’s formative evaluation, which includes the stages of preliminary, design, and formative evaluation (self-evaluation, expert review, one-to-one, small group, and field test). The research subjects consisted of three expert validators, namely a content expert, a media/design expert, and a language expert, as well as eleventh-grade students involved in the one-to-one test (3 students), small group test (9 students), and field test (36 students). Data collection techniques included needs analysis questionnaires, walkthroughs or expert validation, student response questionnaires, and pretest–posttest assessments. Data analysis was conducted by calculating validity and practicality percentages using a Likert scale, and effectiveness was tested using a paired-samples t-test with a significance level of 0.05. The results indicate that the developed learning video falls into the very valid category based on expert assessments. Practical testing shows that the media is efficient and receives positive responses from students. Effectiveness testing at the field test stage reveals a significant difference between the average pretest and posttest scores, indicating that the Canva-assisted learning video is efficacious in improving students’ learning outcomes in matrix multiplication. Therefore, the developed learning video is declared valid, practical, and effective for use in eleventh-grade senior high school mathematics learning.Keywords: Canva; Matrix Multiplication; Mathematics; Media Development
