Espinosa, J. A.; Ribas, F.; Lusquiños, F. – Physics Education, 2022
In order to fix some important concepts of Fundamental Physics, either because they are not usually discussed in depth in theoretical classes and much less at laboratories, or because they are not sufficiently developed in textbooks, it is more effective not to tackle them directly, but to propose a mental or practical experiment to attract the…

Resbiantoro, Gaguk; Setiani, Rahyu; Dwikoranto – Journal of Turkish Science Education, 2022
The difference between students' ideas and scientific conceptions, is called misconceptions. Physics learning needs to be designed by teachers to eradicate misconceptions. This paper provides a review of 72 international journal articles on diagnosis methods, causes, and ways of remediating misconceptions that have been published between…

Martinez-Perdiguero, Josu – Physics Teacher, 2019
The photoelectric effect is one of the key experiments taught during first- or second-year university and high school modern physics courses. It is usually the first experiment to introduce light quantization and the concept of photons as "packets of energy." Here, we want to point out a widespread mistake concerning the interpretation…

Valdez, Perla; Smith, K. Christopher – Journal of Chemical Education, 2020
A common misconception about dissolving is that heating and/or stirring are required for the dissolving process to occur. In this study, quantitative experimental evidence was collected and analyzed to demonstrate that neither heating nor stirring is required for dissolving. Educators can use the data and results in this study to address this…

Myer, Rachel A.; Shipley, Thomas F.; Davatzes, Alexandra K. – Journal of Geoscience Education, 2018
The ability to accurately reason using three-dimensional visualizations is vital to success in STEM disciplines, particularly the geosciences. One impediment to learning from visualizations is spatially-based misconceptions. Such errors can arise from a range of sources (e.g., prior beliefs, inaccurate application of analogy, and visual…

Thysiadou, Anna; Gaki, Vaso – Journal of Technology and Science Education, 2021
The introduction of the computer into the educational process is a fact. The educational use of new technologies creates a new, more appealing and enjoyable learning environment. The introduction of new technologies into school differentiates the role of the professor by giving him/her a guiding character in a process of experiential approach to…

Mataka, Lloyd; Taibu, Rex – International Journal of Research in Education and Science, 2020
A quasi-experimental control group pre- and post-test study was used to determine the effect of a Multi-Step Inquiry (MSI) approach on pre-service elementary school teacher's conceptual understanding. The MSI study involved the development of a conceptual workbook, and a Physical Science Concept Inventory. The conceptual workbook has activities…

Rowe, Laura; Kubalewski, Maria; Clark, Robert; Statza, Emily; Goyne, Thomas; Leach, Katie; Peller, Julie – Journal of Chemical Education, 2019
Environmental pollution is both a worldwide and a local issue, and microplastic pollution in particular is receiving increased attention due to its prevalence and bioaccumulation potential affecting the food chain. This laboratory experiment uses current, research-based methods such that the students can determine the extent of microplastic…

Bain, Kinsey; Towns, Marcy H. – Journal of Chemical Education, 2018
The concept of energy is of central significance, as it is a core disciplinary idea in chemistry and a cross-cutting concept in the sciences. This study sought to investigate student understanding of energetics and associated thermodynamic functions in chemical reactions and processes across a sample of introductory-level undergraduate chemistry…

Perez-Benito, Joaquin F. – Journal of Chemical Education, 2017
The elementary reaction sequence A ? I ? Products is the simplest mechanism for which the steady-state and quasi-equilibrium kinetic approximations can be applied. The exact integrated solutions for this chemical system allow inferring the conditions that must fulfill the rate constants for the different approximations to hold. A graphical…

Eshach, Haim; Kukliansky, Ida – International Journal of Science and Mathematics Education, 2018
The present study uses the intuitive rules theory as a framework to examine whether some of the difficulties in dealing with errors and uncertainties observed among students in the university physics laboratory can stem from their use of intuitive rules. The study also examines the relationship between the use of intuitive rules and laboratory…

Best, Katherine T.; Li, Diana; Helms, Eric D. – Journal of Chemical Education, 2017
The electrophilic addition of a hydrohalic acid (HX) to an alkene is often one of the first reactions learned in second-year undergraduate organic chemistry classes. During the ensuing discussion of the mechanism, it is shown that this reaction follows Markovnikov's rule, which states that the hydrogen atom will attach to the carbon with fewer…

Kizito, Ndihokubwayo; Kinya, Shimizu; Hideo, Ikeda; Takuya, Baba – Online Submission, 2019
This study is investigating the student-teachers' conception of static electricity in Rwandan teacher training colleges. The study used a pre- and post-intervention design, where two groups of students were randomly assigned in two groups. Along a period of four weeks, one group was taught using the traditional method (TRAD) while another using…

Yoshikawa, Masahiro; Koga, Nobuyoshi – Journal of Chemical Education, 2016
This study focuses on students' understandings of a liquid-gas system with liquid-vapor equilibrium in a closed system using a pressure-temperature ("P-T") diagram. By administrating three assessment questions concerning the "P-T" diagrams of liquid-gas systems to students at the beginning of undergraduate general chemistry…

Kozliak, Evguenii I. – Journal of Chemical Education, 2014
The molar entropy of mixing yields values that depend only on the number of mixing components rather than on their chemical nature. To explain this phenomenon using the logic of chemistry, this article considers mixing of distinguishable particles, thus complementing the well-known approach developed for nondistinguishable particles, for example,…
