Abstract

The purpose of this study is to ascertain how class IX students at SMP N 4 Sungai Penuh self-confidence and mathematical disposition relate to one another. The 113 pupils in class IX of SMP Negeri 4 Sungai Penuh comprised the study's population. This study will use a probability sampling technique, specifically simple random sampling with the use of the Solvin formula, to select 30 students to serve as the sample. Correlational research is the type of study that this study is. The F test significance test, the Pearson product moment correlation calculation, and a comparison with the F table are the steps in the data analysis procedure utilized in this study. The study's findings suggest that self-confidence and mathematical temperament have a positive but negligible impact on the mathematics learning achievement of SMP N 4 Sungai Penuh class IX pupils. The study's findings demonstrated that, at a significance level of 0.022 < 0.05, the self-confidence variable had a positive and substantial impact on learning achievement. The mathematical disposition variable likewise significantly and favorably affects student learning achievement. Student learning achievement was positively and significantly impacted by the variables of self-confidence and mathematical disposition, with a coefficient of determination of 0,428.

Abstract

During the Covid-19 pandemic, the implementation of learning in schools underwent a change from face-to-face learning in class to online learning. One form of online defense that is carried out at SMPN 3 Sungaipuh is learning mathematics using the Photomath application. The purpose of this study was to determine the planning, implementation, evaluation and constraints encountered in learning Mathematics using the photomath application. This type of research use a descriptive qualitative analysis approach. Data collection techniques are observation, interviews, and documentation. The results of this study are that in implementing Mathematics learning assisted by the photomath application in solving Mathematics problems can be done in 4 stages, namely: (1) The planning stage, which starts from the stage in recognizing the photomath application and downloading it on the teacher's and students' android. (2) The stage of implementing the photomath application, which is the stage that starts from writing questions, taking photos and scanning questions, answering questions and solving steps in the photomath application, copying questions, working on practice questions, and evaluation/assessment, (3) Evaluation results Mathematics learning with the help of the photomath application has been going well as seen from the 20 grade VIII students of SMPN 3 Sungai Full who managed to solve the problems well as many as 15 people. (4) Constraints/weaknesses in using the photomath application are difficult for students who do not have an Android which will make students only copy answers. Based on the results of the research above, researchers suggest using the photomath application to help teachers teach students to answer sample questions quickly and in complete steps -the steps.
