The implementation of project-based learning in STEM activity (water filtration system) in improving creative thinking skill

Abstract

This research is concerned with STEM activity making water purifier filter. The experiment class applies project-based learning, while the traditional class is taught using conventional teacher talk or explanation. This research used triangulation methods. The quantitative methods were applied to analyze student achievement tests according to creative thinking skills in making water filtration design. The qualitative method was applied using observation of student activity, presentations, and interviews for selected students. The student achievement test was analyzed and coupled with pretest and post-test quasi-experimental research. The collected data were analyzed using inferential statistics in the form of an independent sample t-test to express creative thinking skills. The result of the pre-test indicated the sig (2-tailed) of 0.965, with a significant value of 5% (p>0.05). This result indicated two classes were homogenous. The data analysis of the post-test indicated value of sig (2-tailed) 0.00 where p≤0.05, which implied the student achievement test on creative thinking skills criteria in the experimental class was better than that in the control class.

The Effects of Project Based Learning Model toward Students’ Creative Thinking Skill on Civics Subject

“…One applicable model to support implementation of these skills is projectbased learning (PjBL) model. According to (Nuryati et al, 2020;Ridlo et al, 2020;Safitri & Suparwoto, 2018;Yamin et al, 2020;Yustina et al, 2020) stated that this learning model can create independence, collaboration and increase morale and self-esteem during learning because they undergo learning in accordance to their interests. Furthermore, it is stated that learning using Project based learning model can be done by providing opportunities for them to conduct studies based on students' theme of interest and the condition of the students and the results are different.…”

The Implementation of Integrated Project-Based Learning Science Technology Engineering Mathematics on Creative Thinking Skills and Student Cognitive Learning Outcomes in Dynamic Fluid

“…Creative thinking skills are essential in education and prepare students for the real world of professional work (Ridlo 2020). Students are expected to synergize between knowledge and student application of content and think creatively to provide solutions in dealing with a situation from a different perspective (Hardiman 2010;Rotherham & Willingham 2009;Setya Putri et al 2017).…”

STEM-Based E-Module in Improving Students' Mathematical Creative Thinking Ability: A Needs Analysis for Indonesian Students

“…STEM memberikan kesempatan kepada siswa untuk mengintegrasikan interdisipliner seperti sains, teknologi, teknik, dan matematika dalam pembelajaran biologi sehingga keterampilan siswa dapat dikembangkan (Khalil & Osman, 2017;Kubat & Guray, 2018). Khalil & Osman (2017) dan Nugroho, Permanasari, & Firman (2019) menyatakan bahwa STEM dapat meningkatkan keterampilan abad 21 siswa, seperti kemampuan berpikir kreatif (Ridlo, Nuha, Terra, & Afafa, 2020;Suherman et al, 2020). siswa sangat siap untuk menggunakan e-modul yang terintegrasi STEM karena semua siswa memiliki smartphone yang dapat digunakan untuk mengaksesnya (Safitri, Haryanto, & Harizon, 2021).…”
