Abstract

This study aims to find out how the relationship between self-efficacy and learning achievement. This research approach is a quantitative correlation approach with the type of ex-post facto. This research was conducted at STKIP Al Amin Dompu. The research posulation is all students at STKIP Al Amin Dompu. The sampling technique used random sampling which totaled 30 students. The research instrument used a Likert scale type sheet with a total of 20 items and a description test sheet with a total of 5 items. Data collection techniques using questionnaires and tests. The data analysis technique used the product moment correlation test with SPSS type 29.00 for windows. The results showed that there was a significant relationship between the variable self-efficacy and learning achievement because the significant sig (2-tailed) was less than 0.05 or 0.01 <0.05. r count (Pearson Correlation) is greater than r table or r count > r table which is equal to 0.675 > 0.361 which indicates a relationship or correlation between self-efficacy variables and learning achievement and has a positive relationship. The level of relationship between self-efficacy variables and learning achievement is in the strong criteria

Abstract

This study aims to determine whether or not there is a difference in mathematical problem solving abilities between students who apply the Problem Based Learning (PBL) learning model and students who apply Group Investigation (GI) learning. This research is a true-experimental quantitative approach with a post-test only control group design. The population in this study were all class X SMA IT Ad-Dakwah. The sample in this study was class XA which was taught using the problem based learning (PBL) learning model and XB was taught using group investigation (GI). The number of research samples is 40 students. The instrument of this research was to use a final test sheet for problem solving abilities. Data collection techniques using tests. The data analysis technique uses one-way ANOVA analysis with prerequisite tests, namely the Normality Test and Homogeneity Test. Analysis using the SPSS application version 29.0 for Window. The research results obtained were that there was a significant difference in the problem solving abilities of students who studied using the Problem Based Learning (PBL) learning model with the problem solving abilities of students who learned using the Group Investigation (GI) learning model. Obtained a significance value lower than the significance level of 0.05 (5%) or 0.001 <0.05 and F count is greater than F table or 12, 661 > 4, 098. The average value of PBL students is 80.90 and students GI of 73.80.
