Kácovský, Petr; Snetinová, M.; Chvál, M.; Houfková, J.; Koupilová, Z. – International Journal of Science Education, 2023
In this study, we focused on students' intrinsic motivation towards practical work, more specifically the strength of predictors for intrinsic motivation. As a research tool, we used a modified Intrinsic Motivation Inventory supplemented by additional questions on attitudes towards physics. The respondents were more than 2000 Czech upper secondary…

Chaijalearn, Yuttana; Saleekhum, Parinya; Lordkeaw, Chonlasit; Ratchawet, Anodar; Intharawiset, Thanin – Higher Education Studies, 2023
The research aimed to 1) build and assess suitability of the learning management plan of the predictive-observation-explanatory (POE) technology based learning approach to promote scientific explanation making about the change of the substance for primary school students, 2) to distill the lesson learnt of the predictive-observation-explanatory…

Dutton, Nicole A. M. – American Journal of Distance Education, 2023
An increase in online science course offerings requires a closer evaluation of the online laboratory experience. While it has been established that students can successfully learn from online laboratory simulations, there is a lack of knowledge regarding factors that impact student success. Grounded in the constructivist learning theory, a unique…

Juyeon Lee; Taesoo An; Hye-Eun Chu; Hun-Gi Hong; Sonya N. Martin – Asia-Pacific Science Education, 2023
This study aimed to develop a specialized rule-based AI chatbot tailored for a sixth-grade optics unit and to evaluate the impact of the implementation of the chatbot on students' cognitive and affective outcomes related to science within the classroom setting. Specifically, this study explored how factors such as gender and achievement levels…

Stewart, John F.; Gustafson, John E.; Moore, Michael E.; Forshee, J. Lance; Canaan, Patricia; French, Donald P. – American Biology Teacher, 2023
Students who experience research as undergraduates tend to remain in science, technology, engineering, and mathematics fields. Since course-based undergraduate research experiences (CUREs) are often expensive to implement, we developed a relatively inexpensive first-semester research course for majors entitled "Freshman Research in…

Xinyan Lin; Xiaoshuo Jin; Chunxiu Xu; Heyun Lai; Manbin Lin; Nailin Ren; Longfei Cai – Journal of Chemical Education, 2023
We describe an iodometric titration method for the determination of ascorbic acid using a microfluidic paper-based analytical device([mu]PAD). The ascorbic acid was detected by measuring the length of the blue band formed in a straight paper channel delimited by wax. This analytical method was designed as a laboratory experiment for under…

Alexandria Parker; Evan Noronha; Amanda Bongers – Journal of Chemical Education, 2023
The rise of global environmental issues has stressed the importance of sustainability and green chemistry teachings. Nevertheless, these topics remain largely untouched in most post-secondary organic chemistry lecture courses. This article investigates the barriers to integrating green and sustainable chemistry into organic chemistry classrooms…

Lindén, Johan; Fogde, Anna – Physics Education, 2022
An ordinary soap bubble immersed in a pure carbon-dioxide atmosphere, created e.g. by sublimating chunks of dry ice (solid CO[subscript 2]), will expand within a few minutes to a volume exceeding the original one with a factor of almost ten. Considering that the bubble simultaneously experiences a cooling of ~30 ?C one would perhaps expect a tiny…

Baqi, Younis – Journal of Chemical Education, 2022
A fast, operationally simple, and reproducible synthetic protocol for anthraquinone dyes (AQDs), suitable for upper-division undergraduate industrial and organic chemistry laboratory courses, has been developed. This experiment is composed of three stages; the first step deals with the synthesis of AQDs, followed by a purification step, and…

Wang, Jixin; Zhou, Wenshui; Yu, Mei; Zhu, Zheng; Li, Ying – Journal of Chemical Education, 2022
Cola beverages are widely consumed and popular among students; they can be used as safe reagents to replace toxic chemical dyes. In this study, a safe and improved experiment is described, which successfully demonstrates Beer's law and adsorption process using activated carbon as the adsorbent and cola as the adsorbate. The results of this study…

Weiss, Kathleen A.; McDermott, Mark A.; Hand, Brian – Studies in Science Education, 2022
Educational initiatives in multiple disciplinary areas call for student engagement in the practice of argumentation (CCSSI, 2010a, 2010b; Mullis & Martin, 2017; NGSS Lead States, 2013; OECD, 2018). In science education, immersive argument-based inquiry (ABI) is one category of approaches which integrates argumentation in all classroom activity…

Klopfer, Leo E.; Aikenhead, Glen S. – Science Education, 2022
This article offers a retrospective synopsis of 70 years of development of a humanistic approach to science education. Instruction using the history of science, for example, provides a rich context for students to learn not only canonical science content on a need-to-know basis, but also content from the other domains of humanistic science…

Osterheider, Mattis; Bourdon, Bjoern; Boettcher, Rasmus; Beeken, Marco; Imlau, Mirco – Physics Education, 2022
Spectrometers play a decisive role in the education of A-level and/or under-graduate students in the field of natural sciences. They are capable to demonstrate atomic emission, transmission, reflection and fluorescence spectra, but can be used for wavelength filtering, as well. Here, we present a do-it-yourself spectrometer setup based on a…

Juan Paulo Jimenez Pavez – ProQuest LLC, 2022
Nature of Scientific Knowledge (NOSK) and Nature of Scientific Inquiry (NOSI) are important components of scientific literacy and important educational objectives in science education. Recent literature theorizes that understanding both NOSK and NOSI increases students' understanding of science content knowledge. However, this assumption has yet…

Emily Cole Harris – ProQuest LLC, 2022
This quasi-experimental study aimed to determine if there is a statistically significant difference in student test scores when a modified instructional sequence in middle school science is used versus the instructional sequence suggested by the Commonwealth of Virginia. The Grade 8 science cumulative Standards of Learning (SOL) test results from…
