Developing d-Worksheets by applying 7 steps of problem-based-learning to enrich students’ critical thinking skills

Abstract

Abstract Critical thinking is important for students in developing critical thinking skills. Critical thinking is able to determine actions related to a wide variety of information. The benefit of critical thinking is to prevent students from the massive influence of hoax news that is widely circulating today. Critical thinking also plays a key role in making decisions. This ability can be developed in lectures through the right method. To make it more optimal, learning can obviously be managed to use good quality worksheets. The objective of this study is to design a draft of digital worksheets (d-Worksheets) based on the Problem-Based-Learning (PBL) that is valid for improving students’ critical thinking skills. The research procedure used Borg & Gall’s method classified into four steps, namely 1) Analysis of products to be developed, 2) Initial product development 3) Expert validation and revision 4) Small-scale field trials and product revisions. The research results show that the form of d-Worksheets draft using Adobe Flash is compatible with laptops or computers. The draft of d-Worksheets contains information, images, and interactive videos. The draft was designed for the health science lecture on the health topic of a human circulation system, implementing seven steps of PBL, and referring to expected critical thinking skills. Thus, the draft of d-Worksheets is developed to meet the feasibility according to experts, but it requires further revisions. The draft can increase critical thinking skills according to the experts and students’ experiences.
