Model-Based Reasoning in the Deductive Laboratory Work with Arduino and Sensor Module

Laboratory work that has been applied so far is more dominant in deductive laboratory work, but this type of laboratory work is not optimal in stimulating students' reasoning ability. Up to now, model-based reasoning studies on laboratory work have been substantial (especially in measurement and troubleshooting activities) and have not seen overall laboratory activity, including the use of alternative instrumentation such as Arduino and its sensor module. Designing the best laboratory work requires the role of model-based reasoning studies using Arduino devices. A mixed-method research design was used in this study with a theoretical study to obtain a predictive pattern for deductive laboratory work model which was matched with the observations of 50 undergraduate physics education students in laboratory work. Revision activities were shown by students in laboratory work depending on the capabilities of reasoning. The results of this study indicate that revision activities in deductive laboratory work using Arduino can stimulate students' reasoning. Arduino can lead students to explore their thinking and reasoning to solve problems in laboratory work.

Abilities of Physics Education Students in Constructing Graphics Based on Practicum Results and in Interpreting It

The skills to construct and interpret graphs are a form of science skills and are an important component in learning physics. The purpose of this study was to describe the ability of undergraduate physics education students to construct graphs based on practicum data and interpret them. Data obtained through respondent answer sheets, thinking-aloud recordings, and interviews. The research was conducted at the Faculty of Teacher Training and Education (FKIP) Untad and the research subjects of the Physics Education Study Program students were 6 people obtained based on the values of Basic Physics I and Basic Physics practicum II then divided into three groups of levels (high, medium, and low) with each category as many as 2 people. The results of this study indicate: 1) in general, respondents in the high, medium, and low categories can construct graphs but are not based on the prerequisite ability to construct graphs, especially in determining the x-axis and y-axis variables, 2) on the ability to interpret graphs, respondents can interpret graphs the relationship between variables on the graph but not supported by an explanation or evaluation based on proper physics concepts, 3) The strategy used by respondents in constructing graphs, in general, is to convert data in decimal form or scientific notation and 4) The difficulties experienced by respondents when constructing graphs are converting data, determining the scale and how to determine the variables on each graph axis.

Emerging and Persistent Issues in the Delivery of Asynchronous Non-Traditional Undergraduate Physics Experiments

Remote physics laboratory activities are common tools of use in physics in traditional, online, and distance education to enhance student learning. Although these offerings necessitated by technological advances, spur innovation and improvement in undergraduate physics education, their use as stand-alone substitutes for instructor-guided physical laboratory experiments remain the center of debate and research. This paper discusses the effectiveness of the current pedagogic issues in the delivery and learning of four different types of remote introductory undergraduate physics laboratory activities, the breakthroughs, and the areas that require further investigations. The instructional issues include experiment preparation and design, student engagement, guidance, and safety. This review noted the positive impacts of stand-alone remote physics lab activities on mostly undergraduate non-physics majors, partly due to the limited number of institutions currently conferring complete online/distance physics degrees worldwide. We recommend further studies on the effect on physics students who end up in experimental physics-related careers.

Demystifying the scaffolding required for first-year physics student retention: contextualizing content and nurturing physics identity,

Graduates of physics degree programs are a critical element in the development of a scientifically literate, economically competitive society as discussed by the National Research Council in 2013 (Adapting to a changing world: Challenges and opportunities in undergraduate physics education. National Academies Press, Washington, D.C. 2013). This qualitative case study invited students at a university in Atlantic Canada to participate in a post-course survey to investigate what influenced them to major or to not major in physics. Sixty students participated in the survey portion of the study, of a possible 121, and the survey data was cross-referenced with data from two student interviews, one professor interview, and one laboratory technician interview. Results indicated that student participants were more likely to choose a physics degree program if they felt that they had enough interest in the subject matter, they had experienced good teaching, and they could see how to apply the degree to a career. In addition, a newly implemented, research-based laboratory curriculum proved beneficial, especially for female students. Fifteen percent of participating students continued into a physics major, which is more than the average of under 10% reported by Nicholson and Mulvey in 2016 (Roster of physics departments with enrollment and degree data, 2013. Focus on: American Institute of Physics. 2016. Available from https://www.aip.org/sites/default/files/statistics/rosters/physrost15.1.pdf ). This study provides a Canadian perspective on the choice to major in physics or not, which had been missing from the literature. Findings from this case could be infused into other first-year physics courses to boost student retention rates.

Pengembangan Media Pembelajaran Interaktif tentang Optika Berbasis Android Menggunakan Perangkat Lunak Ispring Suite 7.0 untuk Mahasiswa S-1 Pendidikan Fisika pada Pokok Bahasan Interferensi Cahaya

<p class="AbstractEnglish"><strong>Abstract:</strong> Light interference in the course Optics at undergraduate Physics Education is an abstract subject, and students need a practical, interactive medium for learning independently the material already given in lectures by the lecturer, especially for problem solving exercise. Therefore a study has been performed to develop an android-based interactive learning medium on light interference in Indonesian using the software Ispring Suite 7.0. The study was based on the ADDIE development model, which includes the steps: analysis, design, development, implementation, and evaluation. The feasibility of the medium was validated using questionnaires by subject experts, media (IT) experts, and students as users. The feasibility level of the medium given by the subject experts, the media experts, and the students are, respectively, 87.94 %, 90.44 %, dan 87.99 %. It is concluded that the medium developed is highly feasible for independent learning.</p><p class="KeywordsEngish"> </p><p class="AbstrakIndonesia"><strong>Abstrak: </strong>Pokok bahasan interferensi cahaya dalam mata kuliah Optika S-1 Pendidikan Fisika bersifat abstrak, dan mahasiswa memerlukan media interaktif yang praktis untuk belajar secara mandiri materi yang diberikan dosen dalam tatap muka, terutama untuk berlatih soal secara mandiri.
