Abstract
The learning process has not emphasized the development of skills; this is because in learning students tend to memorize concepts so that learning outcomes and self-efficacy are not trained optimally. The formulation of the problem in this study is: is there a difference in learning outcomes and student self-efficacy between the use of the Problem Base Learning model combined with the E-STEM-based Student Worksheet with the Problem Base Learning model on environmental pollution material at MAN Banda Aceh? This research is quantitative with an experimental research approach. The research design used was pretest-posttest control group design. The population of this study was all students of class X MAN 3 Banda Aceh, totaling 84. The sampling technique used a total sampling of 84 students. The instrument used to measure learning outcomes is multiple choice questions using 30 questions and self-efficacy is measured using a questionnaire. Data analysis of learning outcomes and self-efficacy of students using independent sample t-test at a significant level of 0.05. The results showed that there were differences in student learning outcomes and self-efficacy after applying the Problem Base Learning model combined with the E-STEM-based Student Worksheet on environmental pollution materials at MAN Banda Aceh
Highlights
Learning is generally defined as a change in an individual through experience, and not because of the growth or development of his body or the characteristics of a person from birth that learning and development are closely related
The results showed that there were differences in student learning outcomes between the experimental class and the control class on environmental pollution material at MAN Banda Aceh
The learning outcomes of the experimental class increased significantly compared to the control class, this is because in learning that applies the Problem Base Learning model combined with the Environmental STEM (E-STEM)-based Student Worksheet it provides an opportunity to identify problems related to environmental pollution and find solutions to overcome pollution problems water, air and land
Summary
Learning is generally defined as a change in an individual through experience, and not because of the growth or development of his body or the characteristics of a person from birth that learning and development are closely related. The learning process occurs intentionally or unintentionally and lasts all the time and leads to a change in the learner. Learning outcomes can be interpreted as the maximum results that have been achieved by a student after experiencing the teaching and learning process in studying certain subject matter. Learning outcomes are not absolute in the form of values, but can be in the form of changes, reasoning, discipline, skills and so on that lead to positive changes (Hamalik, 2007).
