Abstract

This study was conducted to determine the effect of the forward model of Problem Based Learning on the generic ability of science students subject to buffer solutions. This research was conducted in class XI MIA Negeri 3 Medan in the academic year 2018/2019. The sample in this study consisted of two classes taken by random sampling, namely the experimental class with Problem Based Learning models and the control class with Direct Interaction models. Data collection techniques with the test method, in the form of questions about the subject of a buffer solution to measure the results of learning chemistry and the generic ability of science students (multiple choice). Data analysis using t test with independent sample t-test technique using SPSS version 20. Based on data analysis, the average value of student learning outcomes using problem based learning models increased from 34.02 to 80 compared to DI models from 31.94 to 74.58. This is supported by the results of hypothesis testing, obtained data that sig (2-tailed) <α or 0.003 <0.05, so that Ha is accepted and Ho is rejected. The data shows that the use of problem based learning models can affect the generic abilities of students' science.Keywords:Generic science skills, Problem based learning

Abstract

This study aims to determine the effect of problem-based learning model (PBL) on students' generic science skills in electrolyte and non-electrolyte solution material. This research is an experimental research. The population in this study were all class X students of SMA Negeri 1 Lubuk Pakam. Sampling was done randomly by taking 2 classes, namely one experimental class (PBL model) and one control class (DI model). The instruments used in the form of objective tests in the form of multiple choices amounted to 20 questions and essay questions to measure students' critical thinking skills as many as 5 questions. Homogeneous and normal data were analyzed by paired sample t-test and N-gain normalized using SPSS Version 20. The results showed that there was an influence of PBL learning models on students' generic science skills in electrolyte and non-electrolyte solution materials. The generic skills of direct observation science are the most developed generic science skills while the lowest generic science skills are symbolic language.

Abstract

This study aims to develop an initial ability test instrument based on science generic skills in the form of a scholastic test and develop a final chemistry evaluation test instrument in the topic of thermochemistry as well as find out the validity of the content and construction validity of the instrument. Research and development research, with a 4D development model consisting of 4 main stages, namely: Define, Design, Develop and Disseminate, due to time constraints this research was only up to develop. The results of the content validity test by experts obtained an average percentage of material aspects, namely 87.08%, construction aspects, namely 90.41%, language aspects, 92.5% and additional rules, 96.67%, so the question instrument is suitable for use. Based on the construction validation test data, it was found that of the 20 questions on the scholastic potential test tested, there were 19 questions that were valid and considered appropriate, while 1 other item was invalid, while of the 20 questions on the chemistry test tested, there were 17 questions that were valid and considered feasible, leaving 3 questions other invalid. For further research, it is hoped that this instrument can be implemented.
