Abstract

Online learning during the COVID-19 pandemic demands quality learning media. One of the learning media is video. Video quality can be improved by editing and setting after the recording is complete. Interesting video shows can eliminate the boredom of online learning for a long period. Especially in learning statistics that require complicated calculations. The purpose of this study is to analyze the needs of statistical learning videos assisted by proshow. This research method is descriptive exploratory. The data comes from the results of a questionnaire of 32 students of SMPN 7 Kotabumi. The results of the study are that students need learning media in the form of learning videos that are easily accessible and interesting so that statistics are easy to understand. The Proshow application can make learning videos give impressive effects.

Abstract

The purpose of describing scaffolding in solving student exponential problems in terms of Brodie's theory. Qualitative descriptive method. Data were collected using tests and interviews with first-semester students of the Mathematics Study Program, University of Muhammadiyah Kotabumi. Research subjects 4 of 28 students of mathematics education study program. In classifying the types of errors using Brodie's theory, namely 1) basic error, 2) appropriate error, 3) missing information, and 4) partial insight. Then the way to overcome student errors is given by scaffolding based on Anghileri's theory, namely environmental provisions, (explaining, reviewing, and restructuring), and developing conceptual thinking. The results of study 1) students' errors in solving exponential questions on basic errors, namely misunderstanding the questions, 2) meaningful learning helps students to better understand the questions, 3) scaffolding is carried out based on the three levels of Anghileri scaffolding, and 4) scaffolding is given in the form of directives so that students better understand the problem.

Abstract

Inequality involving absolute values ​​is an important course material because it is not only studied by mathematics education students but also by mechanical engineering students. In the process of solving inequalities, an absolute value is very reasonable when various errors occur. One theory of error is Kastolan. The identity of Kastolan's theory of errors is in the form of procedural, conceptual, and technical errors. The general purpose of this study was to determine student errors in solving inequalities involving absolute values ​​based on Kastolan's theory of errors and the form of the errors. This research method uses a qualitative research approach with the type of case study. The instruments in this study were: the main instrument and the supporting instrument. The data analysis technique used an interactive analysis model by Milles and Huberman. The conclusion of this study is the student's error in solving inequality problems involving absolute values ​​based on the Kastolan error theory and the form of the error. Conceptual errors in the form of errors in working without using theorems, laws, or formulas, errors in applying formulas, and incorrect problem-solving errors (having errors in determining the sign of inequality, errors in determining the intersection of two inequality conditions, and errors in drawing conclusions or Sets of completion). In addition, the type of technical error with the form of error is a counting error

Abstract

The lack of knowledge that students can absorb on social arithmetic material which is conveyed only through photos of material has an impact on learning outcomes. The development of Android-based M-Learning media is deemed necessary to overcome the problem of low social arithmetic learning outcomes. This study aims to develop social arithmetic android-based M-Learning media for class VII students of Madrasah Tsanawiyah Negeri 1 North Lampung based on expert due diligence assessments. The research and development method used is the ADDIE model (analysis, design, development, implementation, and evaluation). The use of the ADDIE model in research and development is limited so that it is only the ADD (analysis, design, and development) stage. Time is the limit for the stages of becoming ADD. The types of data are quantitative data and qualitative data. Details of the validation results, the material expert validator gets a percentage score of 100% with the assessment criteria Very feasible, no revision needed, the decision from the media expert validator gets a score percentage of 92.8% with the assessment criteria very feasible, no revision needed, the decision from the expert validator language gets a percentage score of 87.3% with very decent assessment criteria, no need for revision. The results of research and development are products in the form of M-Learning based on social arithmetic android for class VII students of MTs Negeri 1 North Lampung with appropriate criteria based on expert judgment

Abstract

The lack of use of learning media to illustrate abstract forms into concrete forms, makes students less understanding of the concepts in cube and block material. This study aims to develop learning media with the help of the Cabri 3D v2 application for understanding concepts in the material of cubes and blocks for class VIII SMP. This study uses the development method belonging to Sugiyono (2017), this research limits its stages only to stage 5, namely until the product revision stage I. After conducting research and development of Cabri 3D v2 assisted learning media, the results are as follows: 1) material experts get percentages 86.66% in the "Very Eligible" category, 2) media experts get 82.22% in the "Very Eligible" category, 3) linguists get 91.42% in the "Very Eligible" category, 4) education practitioners get the result is 100% in the "Very Feasible" category, student responses get a result of 82% in the "very feasible" category. Based on the results of the research, it can be concluded that Cabri 3D v2 assisted learning media for understanding the concept of cubes and blocks material for class VIII SMP, is suitable for use as a learning medium to be able to support the learning process at school

Abstract

This study aims to determine the effect of applying the Learning Cycle 5E model assisted by Macromedia Flash media on the understanding of quadrilateral concepts by seventh-grade students at SMP Islam Alfalah Abung Tinggi. This research uses a quasi-experimental design with the Nonequivalent Control Group Design method. The sample consists of two classes, with the experimental class taught using the Learning Cycle 5E model assisted by Macromedia Flash, and the control class taught using traditional learning models with PowerPoint. Data were collected using a validated descriptive test and analyzed using t-test to examine the differences between pretest and posttest scores. The analysis results show a significant effect of the Learning Cycle 5E model assisted by Macromedia Flash on improving students' concept understanding, with a t-value = 2.863 > t-table = 1.671, indicating that the alternative hypothesis is accepted, and the null hypothesis is rejected. This finding contributes to the development of mathematics education, specifically in enhancing the understanding of quadrilateral concepts through more interactive and engaging teaching methods.

Abstract

The fact of the problem of low critical thinking skills of students is 65.49% in accordance with the provisions of the KKM which is 70. In addition, from the results of observations obtained students are less able to analyze ideas to solve a problem. In addition, students are reluctant to do practice questions that would enable students to be competent in determining strategies and conclusions in solving questions. One of the models indicated as being able to overcome the problem of low critical thinking skills in statistical material is the TPS Model. The study aims to determine whether there is an effect of the TPS model on the critical thinking skills of statistical material for class VII students of SMP Negeri 3 Kotabumi, North Lampung in the 2023/2024 Academic Year. This research method is quantitative experimental with a quasi-experimental design. The form of quasi-experimental chosen is nonequivalent control group design. Then samples were taken from two classes, namely one class VII D for the experimental class using the TPS model and one class VII C using the model commonly used by teachers. The results of data analysis using the t-test, obtained tcount = 3.102 and ttable 1.990 then tcount> ttable so that H0 is rejected, and Ha is accepted. This means that there is an influence of the TPS model on the critical thinking skills of statistical material for class VII students of SMP Negeri 3 Kotabumi
