Wetland environment as learning resource using CTL approach to improve critical thinking in 21st century

Abstract

Tidal water habitat, such as fresh, brackish, or salty water from the wetland environment was local wisdom in South Borneo. Wetland environment can be used as a learning resource on the acid base concept in chemistry learning. This research aimed to determine the effectiveness of the CTL approach using wetland environment as a learning resource to improve critical thinking. Critical thinking skill is one of 21st centuries skill needed. This research used quasi-experiment method with non-equivalent control group design. Samples were taken by cluster random sampling technique. The independent variable was learning approach, and the dependent variable was critical thinking skill. Techniques used to analyse data were descriptive and inferential statistics. The result showed that there was significant difference in critical thinking skill in the experimental and control class. This research concluded that CTL learning was better to enhance critical thinking skill caused by the contribution of the CTL approach such as constructivism, inquiry, questioning, modelling, learning community, and reflection supported by the use of learning resource from wetland environment.
