Implementation of Scientific Approach to Increasing Junior High School Students' Mathematical Problem Solving Ability

This research aims to analyze the learning of class VIII students at Nur Al Rahman Middle School in Cimahi City on linear equations of two variables system material using a scientific approach. In learning mathematics using a scientific approach, especially in linear equations of two variables system material, it is hoped that students can play an active, creative, skilled, and noble character, find and solve problems. The research method used was classroom action research with the subjects studied being 15 class VIII students. This research was conducted for 2 cycles with data collection techniques, namely observation, documentation, and tests in the form of essays that match the indicators of mathematical problem-solving ability. The increase in students' mathematical problem-solving abilities can be seen from the achievement of the percentage of test questions on the problem-solving abilities of the 2 cycles carried out. The instrument used in the research results found that the problem-solving ability skills in linear equations of two variables system material were 33% for cycle I, then 80% in cycle II. This means that learning mathematics in linear equations of two variables system material using a scientific approach has a better influence on students' mathematical problem-solving.

Learning Styles in the Context of Reasoning and Problem Solving Ability: An Approach based on Multivariate Analysis of Variance

Reasoning and problem solving skills are not just for researchers; they are also progressively significant for making knowledgeable decisions in our everyday lives. Showing variations in learning styles have any influence on these skills? The current state of research address the learning styles in context of reasoning and problem solving ability. High school students (598) completed the reasoning ability test, problem solving ability test and learning style inventory. SPSS software was used for evaluating data obtained from three measurement tools. The entire three tools were validated through different techniques and found significant and acceptable. The data was analysed by using MANOVA and Scheffe’s post hoc test. The results indicated that participants showed variations in reasoning and problem solving ability while using learning styles. Moreover, students having assimilating and diverging learning styles possess better reasoning and problem solving ability skills. The results of this research will contribute to the literature of learning styles and cognitive abilities, as well as provide a wide range of implications for class room teachers, curriculum developers, researchers and educational planners.
