Abstract

Skills on the integer system are the main competencies in developing learning in other, more complex number systems, but there are still many students who are not sufficiently proficient in these competencies. This study is an ethnographic study with the aim of describing the mental model and the nature of the consistency of integers that become the learning experience of students at elementary schools in Baubau City. This study provides information that the mental models of elementary school students in Baubau City found in integer learning are initial mental models, synthetic mental models and formal mental models. Students in working on integer addition operations still show inconsistencies when using number line media as a tool.

Abstract

This research was a quantitative research by using experimental method with the research design were pretest-post test control grup design. Population in this research were all seventh grade students of SMP Negeri 8 Baubau in academic year 2021/2022. This research aimed to see the effectiveness of Missouri Mathematics Project (MMP) learning model in improving Mathematics learning achievement of seventh grade students in SMP Negeri 8 Baubau. Sample is this research was taken by using simple random sampling technique, namely class VIIA experimental class and VIIB as control class. The data collection in this research used an essay test, by using data analysis technique, they were descriptive analysis and inferential analysis. The result of inferential analysis by observing the normality test, there was a significant value of students’ Mathematics learning achievement in the experimental class 0,2 and the control class 0,079. While homogeneity test showed that the value of students’ achievement in the class was 0,178 . So that, it could be concluded that the two classes were normality distributie and homogeneus. The by using the t-test, it was known that tcount = 10,230 and significant at = 0,000<0,05, thus H0 was rejected. So that, Missouri Mathematics Project (MMP) learning model was effective in improving students’ achievement.

Abstract

The problem in this research was whether creative thinking was effective reviewed from the mathematics connection in solving problem at SMP Negeri 7 Buton Tengah. The objective of this research was to know the effectiveness of students’ creative thinking reviewed from the mathematics connection in solving problem at SMP Negeri 7 Buton Tengah. This research was experimentalresearch. Population in this research was all grade VIII SMP Negeri 7 Buton Tengah. Sample in this research was taken by using random sampling technique with 44 students consisted of class VIII A as experimental class and VIII B as control class in which each classes consisted of 22 students. Instrument used in this research was test. Research outcome obtained showed that: (1) the result of students’ mean score in pre-test in experimental class was 66.59, while in control class was 62.27. (2) the result of students’ mean score in post-test in experimental class was 80.45, while in control class was 70.68. From hypothesis test result by using t-test, obtained t-count = 3.403 and significant value p = 0.039. Therefore, it could be concluded that students’ creative thinking reviewed from the mathematics connection in solving problem was effective at grade VIII in SMP Negeri 7 Buton Tengah.

Abstract

The formulation of the problem in this study was whether the Brainstorming learning method is effective on the mathematical problem solving abilities of class VII students of SMP Negeri 7 Baubau. The purpose of this study was to find out whether the Brainstorming learning method was effective on the math problem solving abilities of class VII students of SMP Negeri 7 Baubau. This type of research is Quasy Experiment. The population in this study were all students of class VII SMP Negeri 7 Baubau in 3 classes with a total of 85 students. The sample in this study consisted of 2 classes, namely class VII A which consisted of 27 students as the control class. Data collection techniques in this study used test. Data analysis techniques used in this study were descriptive analysis and inferential analysis in the form of t-test. Based on the research results obtained: the average problem solving ability of experimental class students was 77.96; the average problem-solving ability of control class students is 68.70; based on the results of hypothesis testing using the t test, the value of tcount is 2.448. For ttable values at significance level of 0.05 (5%) and df = 52, namely 2.006. Based on this value tcount > ttable then H1 is accepted. So, the data concluded that Brainstorming learning method was effective on the math problem solving abilities of class VII students of SMP Negeri 7 Baubau.
