Ronghui Que; Hongbo Wu; Yalan Zhao; Shasha Han; Min Han; Yan-Lin Xiong; Shanheng Ma; Houxiong Wang – Journal of Chemical Education, 2023
The classic silver mirror reaction at room temperature in textbooks usually used glucose to react with silver nitrate and ammonium nitrate with the presence of caustic alkalis. But the aldehydes such as acetaldehyde and propionaldehyde were difficult to react under the same condition. In this paper, Na[subscript 2]CO[subscript 3] was used to…

Subramaniam, Karthigeyan; Harrell, Pamela Esprivallo; Long, Christopher S.; Khan, Nazia – Research in Science & Technological Education, 2022
Background: Recent literature indicates that the trend towards investigating pre-service elementary teachers' conceptual understanding of science concepts they are expected to teach and their command of that content-specific conceptual understanding is gaining momentum in science education. Purpose: The purpose of this study was to investigate…

Deborah Hanuscin; Emily Borda; Josie Melton; Jamie N. Mikeska – International Journal of Science and Mathematics Education, 2025
Research on teacher educators' professional learning has gained increasing interest within science education. Curriculum materials have been suggested as a means of supporting "teacher" learning for several decades but have not yet been examined as a potential tool for supporting the learning of "teacher educators." In this…

Love, Tyler S.; Napoli, Mary; Lee, Doris – School Science and Mathematics, 2023
Research has revealed that a small percentage of weekly instructional time in the elementary grades is dedicated to teaching science. Additionally, elementary educators receive limited preparation to teach science concepts compared to math or literacy skills. Therefore, this study examined if utilizing poetry to teach science concepts had a…

Barak, Miri; Yachin, Tal; Erduran, Sibel – Research in Science Education, 2023
The goal of this study was to examine the way preservice science teachers depict and develop their understanding of nature of science (NOS), from the perspective of the family resemblance approach (FRA). FRA defines NOS as a Cognitive-Epistemic and Social-Institutional system. Appling the dual-analytic approach via reflective drawing analysis, we…

Sinem Gencer – Journal of Chemical Education, 2023
The main purpose of this study was to describe the development and use of a flowchart for preservice chemistry teachers' problem solving on the First Law of Thermodynamics. Twenty-seven undergraduate preservice chemistry teachers attending a Physical Chemistry course participated in this study. The responses of the participants to the set of test…

Singh, Mamta – Journal of College Science Teaching, 2022
The study assessed the science teaching confidence of preservice teachers in teaching elementary science by addressing two research questions: (1) Did preservice teachers understand the science concepts well enough to be effective in teaching elementary science content? (2) Did preservice teachers have the necessary science concepts and skills to…

Teresa Lynette Leavens – ProQuest LLC, 2023
The purpose of this study was to explore four elementary preservice teachers' (PSTs) learning outcomes based on "affective characteristics," "science knowledge," and "pedagogical content knowledge" during a science methods course that incorporated "explicit instruction on drawing-to-reason" about…

Margulieux, Lauren; Yadav, Aman – Journal of Computers in Mathematics and Science Teaching, 2021
We explored how preservice teachers in a middle school science methods course learned and applied computational thinking (CT) concepts and activities during a month-long intervention. In the intervention, preservice teachers learned about CT concepts through an hour-long lecture in their methods class, practiced a computing-integration activity…
