The Effect of Blended Learning Problem-Based Instruction Model on Students’ Critical Thinking Ability in Thermodynamic Course

Abstract

The course of thermodynamics is one of the subjects whose material content consists of real theory and practice and the use of formulas. Therefore, in the application of this course is a need to apply a learning model that is able to help students find and solve problems and be able to explain their findings in achieving the basic competencies of thermodynamics course. The learning model is a Problem Based Instruction learning model based on Blended Learning. This study aims to improve the critical thinking skills of pre-service physics teacher as a result of using Problem Based Instruction based on Blended Learning in the course of thermodynamics. Retrieval of data in this study was conducted on third semester students of physics education study programs that take Thermodynamics course. This research was conducted in September-October 2019. The research method used is quasi-experimental. Quasi-experiments are research carried out on a single group of students. Data analysis in this study used a one-party t-test. The results showed that (1) the application of the Problem Based Instruction learning model based on Blended Learning can improve students’ critical thinking skills, (2) Students’ responses to the application of the Problem Based Instruction learning model based on Blended Learning get a very happy category of ongoing learning.

Impact of E-Learning Media on Students’ Critical Thinking Skills at Physics Education Study Program, Almuslim University

“…E-learning learning applications will be active if supported by the availability of adequate devices, especially such as Android and a good internet connection [10]. Students can also get the depth of the desired sun through the Moodle e-learning LMS (Learning Management System) [11]. The various advantages possessed by e-learning learning have been applied by the author in a study.…”

“…One of the intended learning outcomes is critical thinking skills. One of the higherorder thinking skills is students' critical thinking skills which are sometimes unable to be explored due to the learning process which is only in the basic pattern [11]. There are many solutions that a teacher can do to explore students' critical thinking skills.…”

“…Critical thinking skills that can be explored in a student are giving simple explanations, giving in-depth explanations, making decisions, making conclusions and taking strategic steps [15]. In detail, these five aspects are Elementary Clarification, In-Depth Clarification, Judgment, Inference, and Strategies [15] Furthermore, the ability to think critically as an ability that will be able to train students in several aspects is observing, focusing, analyzing, assuming, hypothesizing, reviewing, and reflecting [11] [16] [17]. From some of these opinions, it can be concluded that critical thinking skills are high-level abilities of a student, even though these thinking skills are not owned by all students, critical thinking skills can be trained and raised through various learning processes [2] [18].…”

“…Furthermore, Munawar, et al [19] and Akhdinirwanto, et al [20] stated that "the ability to think critically is a thought process that uses the ability to analyze arguments and give opinions based on logical reasoning. Critical thinking indicators consist of providing simple explanations, building basic skills, making references, providing further explanations, and setting strategies and tactics [11]. The teaching media can be in the form of a combination of media with technological sophistication such as learning media with E-learning.…”
