Abstract

This research aimed to reveal the effectiveness of learning with a scientific approach in the STAD type cooperative learning model based on lesson study on mathematics students learning activities. This is a quasi-experimental research where the population was the junior high school students in Rokan Hilir regency which divided into three school levels, namely; high level, middle level and low level. The subject of this research was chosen by applying clustering random sampling method. The second grader of each school was chosen to be the subject of this research by applying purposive sampling. There were experiment and control classes in each subject. The instruments that were used in this research, namely learning media (syllabus, lesson plan and students learning sheet activity) and for the data collection media (question sheet and observation sheet). The design of hypothesis testing of student learning activities in the form of data analysis of student learning activities through statistical tests. Statistical tests used the Kolmogorov-Smirnov data normality test, the Levene variance homogeneity test, the Mann Whitney U difference test, the Independent T-Test, the one-way ANOVA test and continued with the Scheffe test. The result of this research revealed that: students learning activities in the experiment class was better compared to the control class, for every level, there were differences of students learning activities reviewed from school level; and learning with scientific approach in STAD type cooperative learning based o lesson study was effective reviewed from students learning activities. In conclusion, it is proven that learning with a scientific approach in the STAD type cooperative learning model based on lesson study is effective to improve students’ learning activities

Abstract

This research aims to know the effect of using LKPD based of Problem Based Learning model in improving Mathematical Communication Ability of Grade VIII Students at Dwi Sejahtera Junior High School Pekanbaru. The type of this research was Quasi Experimental Research with pretest-posttest control group design. The population was all students of Dwi Sejahtera Junior High School Pekanbaru Academic Year 2019/2020. The samples selection was conducted by using random sampling technique. Based on the result of data analysis, obtained the average score of posttest in Experimental Class 90,87, and the average score of the Control Class is 48,67. It means the average of Experimental Class is higher than the Control Class. The difference test of both averages used t-test obtained significance (2-tailed) 0,000 < α = 0,05 which means the average of posttest score of students’ Mathematical Communication Ability who learn by using LKPD based of PBL is different from the average score of posttest of students’ Mathematical Communication Ability who learn by using scientific learning model. Thus, it can be concluded that there is effect of Problem Based Learning model on students’ Mathematics Communication Ability.

Abstract

This research is a quasi-experimental research with a pretest-posttest control group design. The purpose of this study was to determine the improvement of students' mathematical problem solving abilities using the STAD type cooperative learning model in class VIII of Tunas Pelita Binjai private Junior High School on algebraic operation material. The population in this study were the whole students of class VIII SMP Tunas Pelita Binjai and the sample was randomly selected, namely class VIII-1 (experimental class) and class VIII-2 (control class). The instrument used was a mathematical problem solving ability test instrument. The tests were carried out twice, namely at the beginning of learning (pretest) before receiving treatment and after receiving treatment at the end of learning (posttest). The instrument was confirmed to have fulfilled the validation and reliability requirements. The data analysis was performed using t-test. The finding of this study indicate that there is an improvement in students' mathematical problem-solving abilities using the STAD type cooperative learning model on the subject of algebraic operations significantly. The improvement was seen from the results of the gain score analysis, it was known that the average gain of the experimental class was in the moderate category (0.692) and the average gain of the control class was in the moderate category somehow lower than the experimental class (0.609). The aforementioned findings indicate that there was an improvement in the mathematical problem solving ability of the experimental class which was higher than the improvement in problem solving ability in the control class.

Abstract

The purpose of this descriptive qualitative research was to provide a description of the mathematical critical thinking skills of MTs students in solving mathematical problems, more precisely in the context of a flat side room shape. The research subjects were selected based on the UTS Math score. Subjects who were Grade VIII students of the Riau Technology Islamic Boarding School were grouped into high, medium, and low mathematical abilities. From each group, one student who has good communication skills is chosen as the research subject. After giving tests and interviews to the three subjects, the results obtained showed that the average test for each indicator of mathematical critical thinking skills at the inference stage reached 96.83, the analysis stage reached 88.33, the evaluation stage reached 79.33 and the inference stage reached 59.83. Each subject has different critical thinking skills according to the indicators of mathematical critical thinking skills

Abstract

This article aims to analyze the achievements of each indicator that measures the mathematical comprehension skills of SMAN 10 Pinrang learners on Binomial Opportunity Distribution materials in online learning through the Ms Teams and WhatsApps applications. This research is a qualitative descriptive research that seeks to analyze the mathematical abilities of learners. Imi's research subjects were students of class XII IPA consisting of 29 students. Data collection methods include tests of the level of mathematical understanding of Binomial Peluan Distribution material. Based on the results of the study, it can be concluded that there are 11 people get a score of 80, 2 people get a score of 90, 9 people who get a score of 95 and 5 people get a score of 100. The overall average is 75.27. This indicates that the level of mathematical understanding of learners is able to choose, use precise formulas and calculations.

Abstract

The main issues raised in this research was” how the process and results of the development of mathematical learning model that develops critical thinking skills in brief development mathematical instruction model in fostering critical thinking, colled MICT. The model developed new MICT until the test phase was limited, therefore to determine its effectiveness on a broader scope. Aspects of students' critical thinking applied in this model can be modified by teachers who are interested in implementing this model, modification can be done by adjusting the environment and culture of the students.
