Abstract

Learning media is one of the intermediaries used to convey messages from the teacher to students. In the world of education, learning media are known as intermediaries that are used to convey messages so that students understand the material delivered by the teacher to students so that the learning objectives are achieved. The function of the media was originally only known as a tool in teaching and learning activities that is providing visual experience in order to encourage learning motivation, clarify and facilitate complex concepts. This research aims to find out the effectiveness of mathematics learning media using the Powtoon application, by looking at student learning outcomes Between classes that use learning media using powtoon applications with classes that do not use learning media using the powtoon application. The type of research used is Research & Development, data collection techniques in this study are primary data, namely data obtained from student learning outcomes tests. The data analysis technique used in this study is a quantitative technique. Based on the results of the analysis shows that the learning media developed has been effectively seen from the learning outcomes of students to increase after the use of learning media using Powtoon applications.

Abstract

Teaching materials in schools, such as textbooks and regular Student Worksheets (LKPD), typically only contain summaries of the material and questions, and still lack steps for a learning model. This results in students being less active in the learning process. This study aims to assess the practicality of Student Worksheets (LKPD) based on the Predict Observe Explain (POE) model in mathematics learning. The Predict Observe Explain learning model helps students understand and discover concepts by providing steps that encourage students to express their ideas. The development model used in this study is Research & Development (R&D). The stages of this model include: 1) potential and problems, 2) information gathering, 3) product design, 4) product validation, 5) product revision, and 6) product testing. The population in this study consisted of 20 students from Grade XI at Ekasakti High School, Padang, for the academic year 2024/2025. The results of the study indicate that the practicality of the LKPD was rated as very practical, based on the practicality assessment from both teachers and students. Therefore, it can be concluded that the Student Worksheet (LKPD) based on the Predict Observe Explain (POE) model is feasible and practical for students to use in mathematics learning, specifically in the topic of matrices.

Abstract

Learning mathematics has criteria that not everyone can easily understand. Mathematical formulas that some people find difficult to understand make students bored while studying. Suitable learning media such as animation and pictures will make the process more enjoyable. This research aims to determine the practicality of mathematics learning media created using the PowToon application for class XI Clothing students at SMK Negeri 6 Padang. This research will reveal the level of practicality of using learning media using the PowToon application from both teachers and students after using this learning media in the learning process. The learning media that has been developed and the questionnaire sheets have previously been validated by validators. Based on the research results, it shows that the learning media that has been developed is practical as seen from the practicality test results obtained from teacher responses and student responses. The practicality test results obtained were 81.73% for teacher responses and 77.03% for student responses. From the practical results that have been carried out, the learning media is in the practical category, so it is suitable for use in the mathematics learning process.

Abstract

Enjoyable mathematics learning is the hope of every student. Where learning facilitates students to discover the principles of the material studied in a meaningful way. Teachers can do this by designing interesting learning activities and encouraging students to use their thinking patterns. For this reason, it is necessary to develop mathematics learning tools that can provide opportunities for students to construct knowledge and improve their learning outcomes. So an ACE-based learning tool was developed which is expected to achieve this target. The goal to be achieved from this development effort is to produce effective ACE-based mathematics learning tools. The learning developed is in the form of Student Worksheets (LKPD). The subjects of this research were students of class XI Culinary Arts at SMK N 6 Padang, class This learning tool is effective in terms of student learning outcomes. In this case, the learning outcomes of experimental class students were 87.50% of students scored above the KKM, while 60% of control class students scored above the KKM. Based on these results, it can be concluded that the ACE-based learning tools for mathematics learning in class XI Catering 2 can be declared effective.

Abstract

The purpose of this research is to determine the practicality of Student Worksheets of Plane Figure topics with  cartoons design.  Practicality is indicated by how be convinience to using the worksheet, a time required in the implementation and students' attractiveness of Student Worksheets on students' learning interests.  Students' Worksheets are wished have to influence student learning outcomes and  are expected to increase the learning interest of Grade 3 students at SDN 20 Muaro Sijunjung in plane figure topics. The research procedure  used the Instructional Development Institute (IDI) model that applied principles of the system approach, discovery (define) or needs analysis, development (develop) and evaluation (evaluate). Practicality is investigated through observation of  implementation of teaching and learning process, giving questionnaires of learning interest to students, and interviews students and teachers. Analysis data was carried out descriptively. The results of the learning interest questionnaire can be concluded practically with an average of 78.96%. The results of interviews with students and teachers that LKS with cartoon images are practical from the ease of use, time used, and attractive to students.

Abstract

Learning motivation is one of the main factors determining students’ success in learning mathematics. A lack of learning motivation can cause students to be less actively involved and experience difficulties in understanding the material being studied. Therefore, it is necessary to implement learning strategies that can encourage student engagement and enhance their learning motivation. This study aims to describe the implementation of the Practice-Rehearsal Pairs active learning strategy and its effect on students’ motivation in learning mathematics. The research employed a descriptive approach with students of class XE6 as the control group and class XE8 as the experimental group at SMAN 1 Koto XI Tarusan. The experimental class was taught using the Practice-Rehearsal Pairs active learning strategy, while the control class used the conventional teaching method commonly applied by the teacher. Research data were collected through classroom observations during the learning process and the distribution of learning motivation questionnaires to students. The data obtained were then analyzed descriptively to examine differences in learning motivation between the control and experimental classes. The motivation indicators observed included student activeness, interest in participating in learning activities, perseverance in completing assignments, and students’ level of self-confidence in learning mathematics. The results of the study indicate that the implementation of the Practice-Rehearsal Pairs active learning strategy has a positive impact on students’ motivation in learning mathematics. Students became more enthusiastic, actively participated in learning activities, showed greater perseverance, and demonstrated increased self-confidence. Thus, the Practice-Rehearsal Pairs active learning strategy can be used as an alternative instructional approach to improve students’ motivation in learning mathematics.
