Integrating the Value Pro Environmental Behavior (PEB) and Knowledge of Ecosystem Concept to Improve Students’ Critical Thinking Skill: Environmental Learning Based Project

The critical thinking skill is needed to analyze environmental problems that occur. Along with the increasing environmental damage due to human behavior and activities, a solution is needed that must be sought immediately. Through the learning environment, these skills are used to analyze problems, look for causes and effects of problems, find out how these problems occur and find a solution plan. Learning mini research projects that are integrated with the value of Pro Environmental Behavior (PEB) facilitates the development of this ability by exposing students to "real life" problems which are then carried out a critical study, determining the solution to these problems and followed up with the project. This study aims to see the effect of the learning environment based on a mini research project integrating PEB and ecosystem knowledge to students' critical thinking skills. This research is an experimental study with a 2x2 factorial design. The research variable is a learning model in the form of a mini research project learning model integrated PEB and conventional models, and the attribute variable is ecosystem knowledge which consists of 2 factors: high and low ecosystem knowledge. The instruments used were questionnaires, tests, observation sheets and documentation. The research sample consisted of 97 students. This research was conducted for 6 months. The data analysis technique used descriptive data analysis and 2-way ANOVA inferential statistics. The results showed that there was an effect of this learning model on critical thinking skills; meanwhile, ecosystem knowledge has no effect on critical thinking skills. There is no interaction between the learning model and the level of ecosystem knowledge on critical thinking skills. Thus, these learning models can be implemented in a learning environment.
