Abstract

This experimental research aims to find out whether or not: 1) the probing-prompting learning model affects learning achievement, 2) the self-efficafy affects learning achievement, and 3) the model affects the interaction between the learning model and student’s self-efficacy on learning outcomes. The population in this study were all third grade students of Christian Elementary School Eben Haezer Salatiga as many as 72 students. The sampling technique used Cluster Random Sampling and obtained by grade IIIA students as experimental class used probing-prompting learning model and class IIIC as control class using conventional learning model, with each consists of 24 students. Both models are used in science learning on natural resource materials. The instuments used were the test of science learning achievement and questionnaire about student self-efficacy. Data analysis included descriptive and inferential analysis consisting of normality test, homogenity test with Levene's, early equilibrium test with independent sample t test, and hypothesis test with Anava. The whole test was performed with SPSS calculation tool at 0.05 significance level. The results of the hypothesis testing concluded: 1) there was no effect of probing prompting learning model on students' learning achievements; 2) there was an effect of self-efficacy to the learning achievements; the result of student learning with high self-efficacy category is better (higher) than the moderate and low self-efficacy, and student’s learning result with moderate self-efficacy category was better than the ones with low self-efficacy; 3) There was no effect on interaction between the learning model and self-efficacy on student science learning outcomes.

Abstract

Abstrak: Berpikir reflektif merupakan kegiatan yang  membuat siswa berusaha menghubungkan pengetahuan yang diperolehnya untuk menyelesaikan permasalahan baru yang berkaitan dengan pengetahuan lamanya. Berpikir reflektif meliputi tiga fase/ tingkat yaitu reacting (berpikir reflektif untuk aksi),  comparing (berpikir reflektif untuk evaluasi) dan contemplating (berpikir reflektif untuk inkuiri kritis). Untuk mengetahui tingkat kemampuan berpikir reflektif siswa, maka dilakukan penelitian dengan jenis deskriptif  kualitatif. Subjek penelitian ini adalah 3 siswi kelas VIII SMP Kristen 02 Salatiga yang dipilih secara purposive sampling pada materi bangun datar segi empat dengan kemampuan awal yang berbeda. Dari hasil analisis, siswa berkemampuan awal tinggi dapat dikatakan reflektif, kemampuan awal sedang  dikatakan cukup reflektif, dan kemampuan awal rendah dikatakan kurang reflektif.Abstract: Reflective thinking is an activity that keeps students trying to connect their acquired knowledge to solve new problems related to their old knowledge. Reflective thinking involves three phases / levels of reacting (thinking reflectively for action), comparing (reflective thinking for evaluation) and contemplating (reflective thinking for critical inquiry). To know the level of reflective thinking ability of students, then conducted research with descriptive qualitative type. The subjects of this study were 3 VIII grade students of SMP Kristen 02 Salatiga who were chosen by purposive sampling on the rectangular building material with different initial capability. From the results of the analysis, high initial students can be said to be reflective, the initial ability is said to be quite reflective, and low initial ability is said to be less reflective.

Abstract

This study aims to describe and examine the refractive thinking process of students with intuitive cognitive styles in solving complex problems. This research is an exploratory, descriptive study with a qualitative approach. The prospective research subjects were SWCU and UMS Mathematics Education undergraduate students, totaling 239 students consisting of 155 SWCU students and 84 UMS students. The subjects of this study consisted of 2 students with intuitive cognitive styles. The research instruments include the main and supporting instruments, including complex problems, cognitive style questionnaires, and interview grids. This research results from the refractive thinking process of Mathematics Education students with an intuitive cognitive style in solving complex problems, including perplexity, investigation, construct, evaluation and decision. The stages of an investigation, construct, and evaluation is carried out repeatedly and not sequentially (randomly). The perplexity stage occurs not only at the beginning of the stage but also occurs at each stage of refractive thinking. In addition, students decide to make sewing scheduling guesses based on their intuition.

Abstract

This Best Practice aims to determine the effect of using the Problem Based Learning (PBL) Model assisted by interactive PowerPoint integrated with GeoGebra on students' mathematical problem solving abilities. The subjects of this study were 32 students in class VIII H of SMP Negeri 4 Salatiga for the 2022/2023 academic year. The design used in this best practice uses the One-Group Pretest-Posttest with data analysis techniques using the Wilcoxon signed rank test. Data collection techniques include essay tests, observation of learning implementation, and student response questionnaires. Best Practice results show that the Problem Based Learning (PBL) model assisted by GeoGebra integrated interactive PowerPoint has an effect on students' mathematical problem solving abilities. This can be seen from the results of the Wilcoxon test with a value of Sig.=0.00<0.05 which indicates that there is a difference in the average pretest and posttest results where the mean value after being given the GeoGebra interactive PowerPoint-assisted PBL model is better than the average value before being given this learning model. In addition, the results of learning implementation were 95.59%, and student responses to GeoGebra integrated interactive PowerPoint learning media were 94.14%.

Abstract

This Collaborative Classroom Action Research (CAR) aims to improve learning outcomes in Quadratic Function material using the cooperative learning type TGT (Teams, Games, and Tournament) which assisted by GeoGebra and Quizizz for class X students of SMA N 3 Salatiga. This CAR is carried out in 2 cycles based on the Kemmis and Taggart Theories which consist of 4 stages namely the planning, implementation, observation, and reflection. The subjects of this study were 34 students of class X SMA N 3 Salatiga. The data collection technique of this research uses observation and tests. The data were analyzed using descriptive and quantitative analysis. The results showed that there was an increase in the average value, in the pre-cycle was 77.7; cycle I was 81.6; and cycle II was 83.4. The percentage of classical completeness also shows an increase, students who have scored above KKM (75) in the pre-cycle was 58.06% (18 students), cycle I was 81.82% (27 students), and cycle II was 87.88%. (29 students).
