Abstract

This research aimed to determine: 1) coefficient Correlation betweenthe utilization of learning facilities with mathematics learning outcome. 2)coefficient correlation between independence learning with mathematics learning outcome. 3) coefficient correlation utilization of learning facilitiesand learning independence with mathematics learning outcome.The research was conducted in the even semester of 2019. The samplein this research was selected from the whole population of students ofGrade VIII in An Nur Islamic Junior School Palangka Raya in 2018/2019Academic Year, in total 78 students. Type of this research is correlational.Two instruments used in this research were questionnaires and tests.Questionnaires of utilization of learning facilities consists of 24 validstatements with 0,78 reliability coefficient, questionnaires of independencelearning consists of 24 valid statements with 0,90 reliability coefficient, andthe mathematics learning outcome test consists of 25 valid items with areliability coefficient of 0.85.The research results concluded: 1) there is positive correlation thatsignificant between utilization of learning facilities with mathematicslearning outcome (rhit=0,58), 2) there is positive correlation that significantbetween independence learning with mathematics learning outcome(rhit=0,54), 3) there is positive correlation that significant betweenutilization of learning facilities and independence learning withmathematics learning outcome (Rhit=0,73), each at a significance level of5%.

Abstract

This study aims to determine the suitability of the distribution of cognitive level questions in the “Matematika Kelas VII SMP” textbook published by the Kemendikbud written by Susanto, et al (2022) and the “Matematika Kelas VII SMP” textbook written by Mairing (2020). This research is an evaluative study, using the discrepancy evaluation model. The data sources in this study were questions in the “Matematika Kelas VII SMP” textbook (Susanto, et al, 2022) (called textbook A) and the “Matematika Kelas VII SMP”  textbook (Mairing, 2020) (called textbook B). Samples were taken using a proportional stratification random sampling technique to determine the number of samples taken in each chapter and the questions that became the research sample. The analysis of textbook questions was based on the cognitive level of the Revised Bloom's Taxonomy, and was evaluated by comparing the distribution of textbook cognitive levels to the cognitive dimensions of the TIMSS 2015 Assessment Framework. Of the 135 questions analyzed in textbook A, the distribution of cognitive levels was 14.8% remembering, 46.7% understanding, 20.7% applying, 9.6% analyzing, 4.5% evaluating, 3.7% creating. Meanwhile, of the 188 questions analyzed in textbook B, the distribution of cognitive levels was 0.5% remembering, 40% understanding, 40.4% applying, 11.2% analyzing, 7.4% evaluating, and 0.5% creating. The results showed that the questions in textbooks A and B were quite good because there were each cognitive level according to the Revised Bloom's Taxonomy in both textbooks. However, the distribution of cognitive levels in textbooks A and B still does not match the proportions of the TIMSS 2015 cognitive dimensions. The distribution of cognitive levels according to the TIMSS 2015 Assessment Framework is 35% knowing (remembering and understanding), 45% applying (applying), and 25% reasoning (analyze, evaluate, and create). Realization of the findings in textbook A is 61.5% knowing, 20.7% applying, and 17.8% reasoning. While the distribution in textbook B is 40.5% knowing, 40.4% applying, and 19.1% reasoning. Both textbooks are still lacking in questions of the reasoning type (analyze, evaluate, create). Thus, both textbooks are of fairly good quality, but improvements need to be made by adding questions at the cognitive level of analyzing, evaluating, and creating.

Abstract

The success of implementing the PjBL learning model in the classroom lies in the teacher's ability to effectively design learning, motivate, support and guide students in the process of determining and completing the project. The aim of this research is to apply project-based learning (PjBL) to Geometry Transformation material for class IX junior high school students to find out how the learning process is perceived by students and teachers. This type of research is descriptive research with the research subjects being class IX middle school students. The research instrument is a lesson plan for 6 meetings, posttest, and mathematics disposition. The results of the research show that the implementation of the PjBL learning model in the classroom is less than optimal, as shown by the students' posttest results which have decreased compared to the pretest scores conducted by the teacher, the mathematics disposition questionnaire has also decreased. However, the project assignments in the form of videos and paintings for each group were completed well. The decrease in grades occurred because conditions at the research location experienced a disaster, namely "smog" around October 2023, this caused the learning process to run less than optimally.

Abstract

This study aims to find out: (1) The relationship between self-efficacy and mathematics learning outcomes of grade X students of SMAN 4 Palangka Raya, (2) The relationship of peer association with mathematics learning outcomes of grade X students of SMAN 4 Palangka Raya, (3) The relationship of self-efficacy and peer association with the mathematics learning outcomes of grade X students of SMAN 4 Palangka Raya. This research was carried out in the even semester of the 2023/2024 academic year. The study population was 515 students with a sample of 221 students. Based on the results of the trial, the self-efficacy questionnaire obtained 36 valid statements with , the peer association questionnaire obtained 28 valid statements with , and the mathematics learning outcomes test obtained 21 valid questions with . Based on the results of the prerequisite analysis test, namely the normality test, obtained for self-efficacy data , peer association data , and mathematics learning outcome test data , while the value , because the three data are not normally distributed, so the test used is nonparametric statistical analysis, namely Spearman rank correlation. The results of this study can be concluded: (1) There is a positive relationship between self-efficacy and mathematics learning outcomes of grade X students of SMAN 4 Palangka Raya; (2) There is a positive relationship between peer association and mathematics learning outcomes of grade X students of SMAN 4 Palangka Raya; (3) There is a positive relationship between self-efficacy and peer association with mathematics learning outcomes of grade X students of SMAN 4 Palangka Raya

Abstract

This study aims to describe the errors and factors that cause students to make mistakes in solving trigonometry problems. This research is a descriptive research with a quantitative-qualitative approach. The data collection techniques in this study were tests and interviews. Based on the results of the study, the errors made by students were∶ (1) fact errors (68.55%), namely students did not write and incorrectly write the symbol or notation of the symbols "α" and "°" in trigonometry material, (2) concept errors (30.65%), namely students could not and incorrectly determine trigonometric comparisons and students did not understand and apply the relationship between special angles and trigonometric comparison formulas, (3) operation errors (53.23%), namely students are unable to complete root form operations correctly and incorrectly enter the value of trigonometric comparisons (4) principle errors (70.16%), namely students are wrong in applying the Pythagorean formula and cannot apply the trigonometric comparison formula. The causes of errors made by students in solving trigonometry problems are∶ (1) remembering, in the form of students' lack of ability to remember material that has been learned from simple to difficult material, (2) understanding, in the form of students' lack of ability to understand the content of previously learned material, and (3) applying, in the form of lack of ability to describe material that has been learned in new situations and involves the use of rules or principles.
