Effectiveness of an inquiry-based learning using interactive simulations for enhancing students’ conceptual understanding in physics

Abstract

Two mixed-methods studies (a pilot study and a main study) were carried out to investigate the effectiveness of a novel inquiry-based learning method (named the Inquiry-based learning with Interactive Simulation -ILIS approach). The studies focused on 10 th grade students' conceptual understandings about force and motion in physics. In each of the studies, an explanatory mixed methods design was adapted to combine a quantitative phase with a qualitative phase. The initial quantitative phase employed a quasi-experimental method. Participants were randomly assigned to the ILIS approach (experimental group) and conventional instruction (control group) as learning methods. All participants were asked to respond to a test (modified Force Concept Inventory) and surveys (confidence in learning and inquiry process skills of hypothesising, operation, communication, and evaluation). The quantitative phase addresses the first research question: What is the effectiveness of the ILIS approach and conventional instruction respectively on student conceptual learning? The subsequent qualitative phase of each study involving interviewing participants to explore the way in which the students and teachers understood the conceptual learning in relation to potential performance achieved with the ILIS approach. The results showed significant gains in conceptual understanding about forces and motion and inquiry process skills by the experimental groups in comparison to the control groups. The students' inquiry process skills showed the same trend as conceptual learning. Confidence in learning also correlated with students' conceptual understanding. In contrast, the results showed that the conventional instruction has the same positive effect on improving students' confidence in learning as the ILIS approach. Qualitative findings induced that students in the experimental group reported individual perceptions and viewpoints. The qualitative phase involved interviews with three teachers and six students. It revealed that the ILIS approach offers meaningful benefits for students' conceptual understanding, which complements the findings from the quantitative phase. The findings suggested that the ILIS approach may have implications as a practical and effective teaching and learning method in enhancing students to develop their conceptual understanding in physics.ii Declaration by authorThis thesis is composed of my original work, and contains no material previously published or written by another person except where due reference has been made in the text.

An Empirical Study on Parents' Choices Apply on Alternative Education: A Case Study of T School in Beijing

“…This further implies that the developed and validated guided IBL materials can be used as alternative learning materials. These results contrast those of previous studies by Koksal and Berberoglu (2012), Duran and Dokme (2016), Abdi (2014), Aulia et al (2018), Cooper, Bailey, andBriggs (2015), Brune (2010), Ferguson (2010, Fan (2015) who regarded IBL more effective than non-IBL approach like the conventional method. However, Lynn (2012) supports the results of this study with her finding that students learn equally and effectively through both inquiry-based and traditional teaching.…”

Inquiry-Based Experimental Design for Enhancement of Teaching and Learning of Chemistry Concepts

“…According to Duran (2016) IBSE increases students' critical thinking in science. The use of IBL in teaching and learning has positive implications as it helps students to boost their conceptual understanding in motion and force (Fan, 2015).…”

Assessment of pre-service physics teachers’ conceptual understanding in electricity and magnetism

“…Science education researches in general and physics education researches in particular have demonstrated that quality physics instruction is a challenge both in the developed and developing nations (Mbonyiryivuze et al, 2019). One of the most prominent contributions of physics education researches was its finding that shed light on the failure of traditional instruction focused on rote learning, mere memorization, and naïve quantitative problem solving in teaching introductory physics courses which do not bring conceptual understanding of physics concepts, principles and laws (Fan, 2015;Gerace & Beatty, 2005). Many students completed their study of physics with severe gaps in their conceptual understanding of concepts in many physics topics in a traditional instruction regardless of physics teachers' efforts (Eshetu & Alemu, 2018;Cahyadi, 2007).…”

“…That is, in one hand, traditional teaching approaches lead to problems of misconceptions and inadequate conceptual understanding in physics concepts, on the other hand; many of the students remain with inadequate explanation of physics concepts after completing traditional instruction. This is because students learn very little from traditional lecture type instruction and it does not encourage them to think by themselves in constructing their own meaning and learning (Fan, 2015;Lasry et al, 2014). The question of quality physics education is still a concern which is continued to the present time.…”
