Abstract

The application of probing and prompting techniques is the application of science and technology by conducting investigations or examinations by relating questions in the form of cause and effect aimed at encouraging or guiding the achievement of satisfactory learning outcomes. The application of probing and prompting techniques as a source of independent learning because it requires the involvement of students in exploring and guiding learning. The application of probing and prompting techniques is expected to make students more interactive in learning. So that student curiosity can increase in accordance with the expected learning objectives. This research was motivated because probing and prompting techniques had never been applied at SMA Negeri 4 Padangsidimpuan. This study aims to determine whether there is an influence of the application of probing and prompting techniques on students' curiosity and learning outcomes on oxidation reduction reaction material in class X MIA SMA Negeri 4 Padangsidimpuan. The data on the curiosity test of students in the experimental class was with an average of 49.37 and in the control class was with an average of 49.17, so students' curiosity was higher in the experimental class. Then classes that used Probing and Promting techniques obtained an average learning outcome test of 36.47 to 79, so there was an increase.

Abstract

In the current COVID-19 condition, which requires that learning be carried out by e-learning, students' creativity in learning mathematics is getting lower. To overcome this problem, this study applied the Pair Checks learning model. The objectives of the increase in students' mathematical creativity taught by the application of the Pair Checks learning model, to know the increase in student activity taught by the application of the Pair Checks learning model, to know the improvement of teacher performance in learning mathematics through the Pair Checks learning model. This type of research is Classroom Research. Where the research subjects are students of class X MIA 1 SMA Negeri 6 Padangsidimpuan for the academic year, 2020/2021, totaling 21 students. Data collection techniques and tools are tests and observations. The analytical technique used is descriptive. The results of this study after using the Pair Checks learning model that is seen from the results of the students' mathematics learning creativity test increased with the percentage gain in the first cycle from 61.9% to 90.48% in the second cycle, and the total percentage increased by 28.58%. Student activity in learning increased, this is evidenced by the acquisition of a percentage of 70.47% in the first cycle and 93.9% in the second cycle with an increase of 24.43%. The ability of teachers to manage learning has increased, this is evidenced by the percentage gain of 72% in the first cycle and 96% in the second cycle with an increase of 24%. So the results of this study show that the Pair Checks learning model can increase students' creativity in learning mathematics, student activities in class X MIA 1 SMA Negeri 6 Padangsidimpuan.

Abstract

The birth of the REACT Model was initiated by CORD in the United States. This learning approach includes five learning principles which include the relationship between concepts (Relating), direct experience (Experiencing), application in real situations (Appliying), cooperation between students (Cooperating) and transfer of learning to other situations (Transferring). This learning approach makes it easier for students to understand and master redox reaction material. The aim of the research is that it is hoped that through this research, it will be possible to find out to what extent the REACT learning model contributes to improving student learning outcomes in understanding the concept of redox reactions. This study is a quantitative study. The sampling method for this study is random sampling. Collect data through learning outcomes tests. In the experimental class the average score obtained after implementing the REACT learning model was 73.33 and 60.33 in the control class and the results of the independent t test using SPSS obtained a sig value of 0.025 0.05 which shows that the REACT learning model can improve results. Study.

Abstract

This study aims to describe the critical thinking skills, self-efficacy, and mathematical problem-solving ability of Grade VII-1 students at Sriwarin School, Thailand, in solving linear equations in one variable. This study employed a descriptive quantitative approach involving 30 students selected through purposive sampling. The research instruments consisted of critical thinking and mathematical problem-solving tests, a Likert-scale self-efficacy questionnaire, interviews, and observation sheets. The results showed that the three variables had the same descriptive distribution: 8 students (26.7%) were categorized as high, 14 students (46.7%) as moderate, and 8 students (26.7%) as low. The class average scores were 54.8 for critical thinking skills, 42.7 for self-efficacy, and 63.2 for mathematical problem-solving ability, all of which were categorized as moderate. These findings indicate that the students' critical thinking skills, self-efficacy, and mathematical problem-solving ability generally showed moderate profiles, with similar category distributions across the three variables. The study provides a descriptive overview of students' critical thinking, self-efficacy, and mathematical problem-solving profiles in learning linear equations in one variable.
