Students^ visual representation of lights and visions Yogi Kuncoro Adi, Ari Widodo, Wahyu Sopandi, and Muslim Universitas Pendidikan Indonesia Abstract Abstract. Visual representations are used by scientists to communicate scientific conceptions and are used by teachers to teach science in the classroom. The 2013 Curriculum textbook reduces this visual representation. Meanwhile, visual representations will help students develop a comprehensive understanding of the concept. We used observations of fifty-nine fourth-grade elementary school students to find students with different cases of misconceptions. Eleven students were further identified using interviews and drawing tests. We found misconceptions in the representation of luminous objects and how students draw visions of luminous objects and non-luminous objects. Research results showed that we found cases of misconceptions similar to the findings from previous studies. While light and vision are prerequisite concepts, a student^s conception of vision is affected when he has a misconception about light. Content can be developed by paying attention to the various modes of representation, conceptual change, and learning progression in the future. The pattern of learning progression can be studied in more detail using the microgenetic method.

Self-efficacy of PCK: An Exploration of Indonesian Pre-service Physics Teacher Perspectives Shelly Efwinda (a*), Zeni Haryanto (b), Nurul Fitriyah Sulaeman (c), Atin Nuryadin (d), a,b,c,d) Physics Education Study Program, Faculty of Teacher Training and Education, Mulawarman University, Indonesia Abstract As physics is considered a difficult subject to be understood, pre-service physics teacher programs face the challenges of providing adequate Pedagogical Content Knowledge (PCK). Pre-service teachers^ self-efficacy is an essential factor affecting their teaching performance in the classroom. This study aims to explore the self-efficacy of pre-service physics teachers in Indonesia. Data were collected through a questionnaire with a Likert scale of 1-9, consisting of 18 statements and reasons for scoring. The self-efficacy questionnaire was divided into three aspects, including the self-efficacy domain Content Knowledge (CK), Pedagogical Knowledge (PK), and PCK. The participants were 71 final year students from 5 Physics Education Study Programs in Indonesia. According to the results, the total self-efficacy score of pre-service teachers in physics was 6.98, which falls into the high category. In the CK, PK, and PCK domains, self-efficacy was 6.91, 7.06, and 6.93, respectively, considered as in the high category. Further analysis of students who responded in the low category showed that pre-service teachers with low self-efficacy tend to be unsure that they have taught well. They believe that they have not fully mastered physics material and the characteristics of diverse students. Also, they have not gained significant teaching experience. According to these results, teacher education institutions must re-evaluate what kinds of learning activities can increase pre-service teachers^ self-efficacy in teaching and increase their teaching opportunities.

Online Microteaching: Unveiling Female Pre-service Physics Teachers Technological Pedagogical and Content Knowledge (TPACK) Shafira Aulia Putri (a*), Puardmi Damayanti (a), Atin Nuryadin (a), Nurul Fitriyah Sulaeman (a) a) Physics Education, Universitas Mulawarman, Jl. Muara Pahu, Gn. Kelua, Kec. Samarinda Ulu, Samarinda *shafira.liaput[at]gmail.com Abstract Global trends show that men dominate physics-related jobs. However, there is a unique phenomenon especially in Indonesia in the physics teacher education program where there are more female students than male students. This study aims to determine the TPACK of female pre-service physics teachers consisting of fifteen pre-service teachers taking microteaching courses and making their online learning videos. The videos were used as a data collection tool. A microteaching observation sheet was used to analyze data obtained from observations with two raters. The observation sheet consisted of 6 aspects which were Content Knowledge (CK), Pedagogical Knowledge (PK), Technological Knowledge (TK), Pedagogical Content Knowledge (PCK), Technological Content Knowledge (TCK), and Technological Pedagogical Knowledge (TPK) with four indicators for each aspect and the maximum score per aspect is four. The overall TPACK score was obtained by calculating the average of all aspects. Although the overall result of female pre-service physics teachers is 2.1 which is sufficient, technological-related aspects need more concern. The results showed that female pre-service physics teachers lack Technological Pedagogical Knowledge (TPK). On the contrary, they have high Pedagogical Knowledge (PK). Teacher education programs should provide opportunities for female pre-service teachers to develop their TPACK. Online microteaching can be the key to helping female pre-service physics teachers to integrate technology into their learning.

Interactive learning in the 21st Century can be done by conducting virtual or real laboratory activities, even by combining the two in one activity at once. Various innovations in virtual laboratories have spread to optical materials, especially refraction by using a virtual spectrometer. Conceptually, refractive index is a measure of the bending ray of a light beam as it passes from one medium to another. The refractive index is given by measurement between the refractive index of air, the angle of the prism, and the angle of minimum deviation. The angle of the prism and the angle of minimum deviation can be measured with a spectrometer. Spectrometer is a scientific instrument used to separate and measure the spectral components of physical phenomena and can separate white light and measure individual narrow color bands. Other than an on-hand spectrometer, other tools that we can use to measure the angle of minimum deviation are by using a virtual spectrometer provided by several virtual labs. Here we report our study on spectrometer whether the virtual lab experiment yields the same result as the real lab. We compare both results of experimental data using data and graph analytics. The results of the study show that the difference in index of refraction measured between the virtual lab and the real lab is about 0.2%. Thus shows that there is no significant difference between virtual lab and real lab.

How Preservice Teachers Perceive Their Collaboration Team Working Skills During PjBL Rifaatul Maulidah, Ernita Susanti, Ifa Rifatul Mahmudah, and Yanti Sofi Makiyah Department of Physics Education, University of Siliwangi, Tasikmalaya, West Java, Indonesia Abstract The PjBL approach is applied to the Physics Laboratory Management course to support the achievement of learning outcomes. Through PjBL, preservice teachers are given assignments related to their future work as teachers and are required to complete them in groups. This study aims to determine how preservice teachers perceive their collaborative skills while interacting with group members when completing assignments. This research applied a mixed-methods approach to better understand research problems by quantitative and qualitative data. We employ total population sampling to examine the entire population with a particular set of characteristics from 67 people who completed the group project assignment. We analyze and describe the quantitative and qualitative data results to answer preservice teachers^ perceptions of their collaborative team working skills during PjBL. We prefer the explanatory design method, where qualitative data is needed to explain the significant quantitative results. As a result, Preservice Teachers^ perception shows that during PjBL, they have obtained collaboration skills in teamwork, managing conflicts, decision making, and communication skills. From the interviews, we dig up additional information about their complaints about the difficulty of completing projects and working in teams. However, the benefits of the additional skills they get are more profitable than their challenges. This analysis informs us that Preservice Teachers show a more significant positive response regarding collaboration skills during PjBL. It can be considered to continue to bring up collaboration skills in any given learning approach Keywords: collaboration skills, pjbl, perceive, preservice teacher Share Link | Plain Format | Corresponding Author (Rifaatul Maulidah)

Comparing Nature of Science Frameworks in Science Textbooks Analysis: Case of Consensus View and Family Resemblance Approach Putra Habib Dhitareka, Arif Hidayat, Parsaoran Siahaan Indonesian University of Education Abstract Nature of Science is a crucial part for enhancing students^ scientific literacy. Textbook is one of the significant and trustworthy source in education to support Nature of Science. One of the common frameworks used in textbook analysis is based on the consensus view of NOS. Then, there is Reconceptualized Family Resemblance Approach as one alternative that considered compatible to the needs of more pluralistic and comprehensive framework. This study aims to compare the two frameworks in the case of representing Nature of Science in textbook analysis. The comparison is focused on the similarity and difference of how both the framework by the working principle and the products whether in general of specific. Content analysis conducted by analyzing 13 documents filtered out of 67 documents within the various purposive criteria. Based on the study, five general themes are emerged from the analysis concerning: coverage, distribution, quality, publisher effect, and depth. Most of the study get into the finding that the representation of NOS in the textbooks are inadequate as well as implicit. Moreover, the distribution is often scattered and limited from the complete aspects. The remarkable point is that FRA has broader spectrum analysis, yet it enables detailed NOS analysis to make it significant in didactic context, while the consensus view-based framework giving ease to large scale study. The textbook analysis study that employs FRA is still sparse, more research using the framework to present in depth analysis of NOS is required to support NOS in didactic context.
