Effectiveness of local wisdom integrated (LWI) learning model to improve scientific communication skills of junior high school students in science learning

Abstract

The previous research has been developed Local Wisdom Integrated (LWI) Learning Model and has been declared that it is valid to improve problem solving skill, scientific communication skills, and environmental care attitude of junior high school students. This study aims to analyse the effectiveness of the LWI Learning Model on improving the scientific communication skills of junior high school students in science learning. This study used one group pre-test and post-test design toward 140 students of junior high school class VII who was divided into 3 groups in SMPN 1 Lingsar and 3 groups in SMPN 2 Gunung Sari, academic year 2017/2018. The data collection was conducted through questioner, observation, and interview. The scientific communication skills of junior high school students were measured by using scientific communication skills Evaluation Sheet (SCSES). The data analysis technique was done by using paired t-test, Wilcoxon test, and N-gain. The results showed that there was a significant increase in student’s scientific communication at α = 5%, with low N-gain and medium category. LWI Learning Model was proved to be effective to improve scientific communication skills of junior high school students in science learning.
