Improving students’ creative-thinking skills in biotechnology using creativity-learning based discovery skill (Cel-Badis) model

Abstract

There are four technologies that will play a role in human life in the 21st century, one of which is biotechnology, and there are 4 skills needed in the 21st century, one of which is creativity. This research aimed to determine the effectiveness of the creativity-learning based discovery skills (Cel-Badis) model to improve the students’ creativity on the topic of biotechnology. This research was a quasi-experimental research with a pretest-posttest control-group design at Sebelas Maret University Surakarta Indonesia in the 2017/2018 academic year with one class as the experimental class using the Cel-Badis model and the other class as the existing class taught with the inquiry learning model. The data were obtained using the creativity test instrument in the form of essays that have passed the experts’ validations, namely the validations from the education and evaluation experts, science expert, and certified science lecturer, as well as empirical validation through trials. The results showed that the average score of the students’ creativity skills in the experimental class was 0.70 higher than that in the existing class of 0.52. The independent sample t-test shows the difference between the experimental class and the existing class with a value of 3.544 and a sig value of 0.001 < 0.05. The effect size test results are in the large criteria. Based on the results of the research, it can be concluded that creativity in novelty, fluency, flexibility, and originality aspects can be increased effectively through the activities of the Cel-Badis model.
