The Influence of Project-based Learning (PjBL) and Learning Style om Mathematics Communication Skills of Junior High School Students

This research is motivated by the low mathematical communication skills of junior high school students in the city of Bandung Regency. This study aims to determine the comparison of the mathematical communication skills of junior high school students in the city of Bandung regency between the learning usingmodels Think Talk Write. The method used in this study is a quasi-experimental method with a pretest-posttest control group design involving two groups and randomly selected classes, at the beginning and end of the study the two classes were given a test. The population in this study were junior high school students in the city of Bandung Regency, while the sample consisted of two randomly selected classes. Obtained class VII A (experimental class) given themodel Think Talk Write and class VII B (control class) is given a scientific approach. The instrument used was a 5-item mathematical communication ability description test, then theability scores mathematical communication students'were analyzed with descriptive and inferential statistics using the help of SPSS 21 software. Based on the results of the study, it was concluded that there were differences in the achievement of students' mathematical communication skills using models Think Talk Write with students who used a scientific approach.

The study was conducted to develop science module based on project-based learning that is feasible to be implemented in science learning and has potency to build critical thinking skills of junior high school students. The study was Research and Development (RD), modified from Borg Gall steps covering only research and information collecting, planning, preliminary form of product development, expert judgment, product revision, and final product. The subjects were 2 expert lecturers (content expert and media expert) and 2 science teachers of SMP N 1 Wonosari. The types of data were quantitative and qualitative. Data were collected by means of SSP validation sheets and disaster preparedness identification sheets. The techniques of data analysis were descriptive analysis of qualitative and quantitative to 5 grading scale. The result of the study shows that science module is feasible to be implemented in science learning and has potency to build critical thinking skills of junior high school students.

The Relationship

The objectives of this study were to profile the relationship of scientific attitude level and learning style preference among junior high school students in Bandung. This study utilized a survey research design with a total sample size of 110 students. A scientific attitude questionnaire and a visual, auditory, and kinesthetic (VAK) learning style inventory were administered in this study. The questionnaire measures five aspects of scientific attitude, specifically rationality, curiosity, open-mindedness, aversion to superstition, and objectivity. The VAK learning style inventory evaluates the preferred means of receiving sensory information. The scientific attitude questionnaire provided consistent results, as indicated by its reliability coefficient (0.896). The results show that junior high school students have an average level of scientific attitude and generally prefer a kinesthetic learning style. There was a medium relationship between scientific attitude and learning style among the students (Cramer’s V coefficient = 0.239). It is concluded that learning style must be considered in implementing a science lesson, especially in the Indonesian context.
