The purpose of this study was to improve students' mathematical reasoning abilities through a guided training approach. This type of research is Class Action Research (CAR). The subjects of this study were students of class XI MIPA 3 SMAN 23 Bandung Academic Year 2018-2019 which amounted to 36 students. The method of data collection is done through a method of testing students' mathematical reasoning abilities.Data analysis techniques use methods that include data collection, data reduction, data presentation, and conclusion drawing. The results of this study indicate an increase in students' mathematical reasoning abilities. This can be seen through the percentage of learning completeness (fulfilling KKM = 70) in each cycle, namely cycle I by 53%, increasing in cycle II by 92%, and increasing again in cycle III by 100%.The conclusion of this study is that the guided training approach can improve mathematical reasoning abilities of class XI MIPA 3 SMAN 23 Bandung Academic Year 2018-2019.
Abstract The purpose of this study was to determine: students' responses to the jigsaw type cooperative learning model, the ability of mathematical reasoning with the application of a jigsaw type cooperative learning model, the effect of applying the jigsaw type cooperative learning model to mathematical reasoning abilities. Data collection techniques used were questionnaires and tests. The population is all students of MTs Al-Munawwir. The research sample is class VII with the sampling technique using cluster random sampling. The results of this study are obtained a positive response to the use of the jigsaw cooperative learning model of 77.10% and the average value of mathematical reasoning ability is 76.54. After testing the hypothesis, it is obtained that tcount(2,375) > ttable(1,708), then Ho is rejected and Ha is accepted, meaning that there is an effect of the application of the Jigsaw type cooperative learning model to the ability of mathematical reasoning. Regression equation Ŷ=33.127+0.447 X.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
