The purpose of this research is to find out how far the effectiveness of the smartboard media is in understanding the concept of the unit time material for students in elementary schools. The research method experimental which a quasi-experimental design (Quasy-experiment). The population of this study was an elementary school located in Tasikmalaya City, using a purposive sampling technique. The data collection technique used is in the form of a test given through the pre-test and post-test. Based on the results of the descriptive statistical analysis and the results of the inferential statistical analysis it was proven that the understanding of the experimental class that was given treatment was better than the control class. This is evidenced by the acquisition of an average value of Sig.(2-tailed) of 0.004, where 0.004 <0.05. This means that Ha is accepted and Ho is rejected, which means that the average post-test final score for the experimental class using smart board media is different from the average post-test final score for the control class without using smart board media. Based on the quality of understanding improvement in the experimental class is in the medium category, while the quality of understanding improvement in the control class is in the low category. So it was concluded that the smart board media effectively influenced the understanding of the concept of time unit material for third grade elementary school students.

Abstract

Self-efficacy is an assessment of a person's belief in the ability or potential that is possessed within him. This self-efficacy is very important for students, because this self-efficacy is a student's self-confidence in their potential, then how do they overcome an action against a given task so that they can achieve the goals they want, and this can also affect their learning outcomes .This study aims to see the effect of self-efficacy on the learning outcomes of students taking the Numerical Method course. The sample of this study were students of the Unindra Informatics Engineering Study Program who took the Numerical Method course. The instruments in this study were self-efficacy questionnaires and post-tests. Data analysis was carried out quantitatively. Data analysis was performed on the post-test data by using a linear regression analysis test. Meanwhile, student self-efficacy is in the form of distributing questionnaires which are then processed quantitatively. The results showed that there was an effect of self-efficacy on student learning outcomes in the Numerical Method course. The regression model test shows that the F test is 109.541 with a significance level of 0.00 <0.05. This shows that there is a significant influence between student self-efficacy on learning outcomes. The value of the correlation coefficient (R) is 0.826, this shows that there is a relationship between self-efficacy and student learning outcomes in the high category. Based on the results of the determinant coefficient (R2) it is obtained that 68% of student learning outcomes are influenced by self-efficacy variables, while 32% are influenced by other factors.

Abstract

By developing students' mathematical communication skills during a pandemic, students can achieve learning success in the implementation of online learning. But in practice, students' mathematical communication skills are still not good. This study aims to review a number of research articles that are relevant to students' mathematical communication skills in online learning. This type of research is Systematic Literature Review or SLR. Data collection techniques are carried out by collecting a number of research articles available on Google Scholar. There were 10 journal articles used in this study. Based on the results of the study, it shows that in the implementation of online mathematics learning, mathematical communication skills in students are classified as low category. This is caused by two factors: 1) from within students, such as student learning motivation; 2) from outside students, such as less qualified learning resource facilities. The solution so that students' mathematical communication skills can improve is by creating innovative learning such as using interactive learning media.Keywords: Mathematical Communication Skill, Online Learning, Systematic Literature Review

Abstract

Learning mathematics in schools is intended so that students have mathematical abilities. Mathematical abilities are trained through mastery of mathematical material. Various alternative uses of learning models have been carried out in accordance with the development of science in education. So this study aims to provide alternative learning options, through the Trigonometry learning design using the POGIL model for high school students. POGIL is a process-oriented and student-centered inquiry learning in an active learning that uses study groups. This writing uses the Dick and Carey instructional design. The development of the Dick and Carey learning design model is a learning design model that follows a systematic approach to developing effective and efficient learning programs. Learning design is done by analyzing the needs of students. Performance objectives and learning outcomes are discussed in detail and adapted to instructional objectives. The results of this study indicate that the trigonometry learning design by applying the POGIL model is recommended for educators. This happens because learning is based on the advantages of the POGIL learning model, which include helping students to discover their own knowledge. In addition, the POGIL Learning Model is also able to assist students in improving process skills, asking questions, and communicating knowledge, and can cover a wide range of subject matter. The POGIL model is also easy to apply to all levels of education..Keywords: POGIL Model, Instructional Design, Trigonometry, High School Students
