Physics Teachers' Perceptions about Diagnostic Assessment of Students' Physics Misconceptions: A Phenomenological Study

Misconception is the difference between a student's idea and his scientific concept. Physics learning needs to be designed by teachers to minimize misconceptions. Different diagnostic tools have been developed and used by researchers to identify student misconceptions. This study addressed to uncover the experiences of eight physics teachers on how they apply diagnostic tools to detect misconceptions experienced by students investigated through phenomenological studies. Physics teachers are invited to volunteer to participate in this research. Physics teachers involved in this research have diversity based on the period of experience teaching physics, geographical area, and the level of students faced. A semi-structured interview (duration of 40 to 60 minutes) through virtually was conducted by the author for all physics teachers involved in this study. Personal Practice Theories (PPTs) by Cornett was chosen as a framework to reveal the experiences and perspectives of physics teachers in making judgments about students' misconceptions of Physics. The findings revealed that four themes were obtained. These themes are (1) personal experiences of Physics teachers, (2) Physics teachers' knowledge, (3) practices in assessing Physics misconceptions, and (4) teachers' reflections on future assessment practice.

Validating Light Phenomena Conceptual Assessment Through The Lens of CTT and IRT Frameworks

Light phenomena conceptual assessment (LPCA) is a conceptual survey of light phenomena that has been recently established by the physics education research (PER) scholars. Studying the LPCA psychometric properties is always imperative to inform its measurement validity to potential LPCA users or beyond general educational researchers. Classical Test Theory (CTT) and Item Response Theory (IRT) are two popular statistical frameworks that can be utilized to explore the LPCA measurement validity. To our knowledge, no PER studies have been attempted to make a head-to-head comparison of those methods while validating the LPCA. This study was the first to delineate the LPCA measurement by statistically comparing the CTT and IRT based analysis. The LPCA dataset was drawn from physics students of eight secondary schools presented by Ndihokubwayo et al (2020). Our results accomplished the harmony between the CTT and IRT arguments to estimate the LPCA item performance and students' ability probed by the LPCA. They supported that the LPCA may be used as inventory for evaluating conceptual understanding of light phenomena from low to high students' ability range even some flagged LPCA items were exist based on CTT and IRT arguments. Special considerations for further refinement related to the discriminating power for some problematic LPCA items are discussed.

Using multilevel modeling to evaluate science literacy and technology course of the Indonesian non-science students

Science literacy is being fostered by science education community including the Indonesian education system. Science literacy and technology course has been designed and implemented to strengthen the national initiative empowering scientifically literate Indonesian society. This paper is intended to evaluate to what degree this course can be performed by non-science undergraduate students (N = 160) considering the nested structure of students' department and faculty setting. Multilevel modeling thus was employed to conduct the analysis dealing with this nature. The first level analysis involved students' performance and affective attribute measured using demonstrated science literacy assessment (SLA-D) and motivational beliefs (SLA-MB) respectively. The subsequent level analysis comprised demographic factors gathered from institutional record. Findings demonstrated that the impact of demographic factor to the students' performance on science literacy was not substantial. Different setting of students' department and faculty level drove the association between affective factor and learning process toward science literacy course substantially. Multilevel approach has controlled the equitable student assessment within the nature of students' data structure. This paper suggests many implications to open ideas regarding educational data analysis and to examine the effectiveness of science literacy course for the higher institution specifically for non-science majors.
