The Effectiveness of Model 4A (Phenomenon Analysis, Information Analysis, Data Analiysis, Finding Analysis) of Analytical Thinking Skills in Secondary School

Abstract

The research aim to describe the effectiveness of model 4A (phenomenon Analysis, information Analysis, data Analysis, findings Analysis) of the analytical skills in secondary school students. Research is conducted with the school population with different accreditation, i.e. accredited A, B, and C. Research samples are class VII students in each school. Research design using quasi experiments. Effectiveness was measured through increased skills of minimal moderate category analytical thinking and a student's positive response to the implementation of the model 4A. Based on data analysis results, it was obtained that there was an increase in analytical thinking skills covering indicators of differentiating, organizing, and attributing with the average N-gain moderates category of each school A, B, and C respectively 0.57; 0.51; and 0.55 and the result a paired t-test, independent t-test, and 2-way variant analysis test showed that there was a change in model 4A impact on analytical thinking skills as well as the student response from schools A, B, and C in ranged between 84-100%; 76-100%; and 75-100% the meaning is very positive. Thus it can be said that the 4A model is effective to improving the analytical thinking skills of secondary school students.
