Karatjas, Andrew; Webb, Jeffrey – International Journal for the Scholarship of Teaching and Learning, 2017
The Kruger-Dunning effect was studied as it related to performance in chemistry courses based on student differences in academic background. Student major was chosen as the classification to look at the effect of students with different interests/specializations. Chemistry majors tended to predict lower performance than biology majors, while…

Irby, Stefan M.; Phu, Andy L.; Borda, Emily J.; Haskell, Todd R.; Steed, Nicole; Meyer, Zachary – Chemistry Education Research and Practice, 2016
There is much agreement among chemical education researchers that expertise in chemistry depends in part on the ability to coordinate understanding of phenomena on three levels: macroscopic (observable), sub-microscopic (atoms, molecules, and ions) and symbolic (chemical equations, graphs, etc.). We hypothesize this "level-coordination…

Marshman, Emily; Singh, Chandralekha – Physical Review Special Topics - Physics Education Research, 2015
Compared with introductory physics, relatively little is known about the development of expertise in advanced physics courses, especially in the case of quantum mechanics. Here, we describe a framework for understanding the patterns of student reasoning difficulties and how students develop expertise in quantum mechanics. The framework posits that…

Wolf, Steven F.; Dougherty, Daniel P.; Kortemeyer, Gerd – Physical Review Special Topics - Physics Education Research, 2012
Since it was first published 30 years ago, the seminal paper of Chi "et al." on expert and novice categorization of introductory problems led to a plethora of follow-up studies within and outside of the area of physics [Cogn. Sci. 5 121 (1981)]. These studies frequently encompass "card-sorting" exercises whereby the…

Hu, Dehui – ProQuest LLC, 2013
Calculus is used across many physics topics from introductory to upper-division level college courses. The concepts of differentiation and integration are important tools for solving real world problems. Using calculus or any mathematical tool in physics is much more complex than the straightforward application of the equations and algorithms that…

Docktor, Jennifer L.; Mestre, Jose P.; Ross, Brian H. – Physical Review Special Topics - Physics Education Research, 2012
Research on physics problem categorization has established that proficient problem solvers are able to group together physics problems that would be solved by similar principles and use conceptual approaches when solving problems, whereas weak solvers rely more heavily upon surface features (objects, contexts, and quantities provided) to identify…

Pardinas, Antonio F.; Dopico, Eduardo; Roca, Agustin; Garcia-Vazquez, Eva; Lopez, Belen – Biochemistry and Molecular Biology Education, 2010
This article describes an easy and cheap laboratory exercise for students to discover their own mitochondrial haplogroup. Students use buccal swabs to obtain mucosa cells as noninvasive tissue samples, extract DNA, and with a simple polymerase chain reaction-restriction fragment length polymorphism analysis they can obtain DNA fragments of…

Al-Balushi, Sulaiman M. – International Journal of Science and Mathematics Education, 2011
The purpose of the current study was to explore learners' evaluation of the credibility of scientific models that represent natural entities and phenomena. Participants were 845 students in grades 9-11 (aged 15-17 years) and 108 prospective science teachers in Oman, totaling 953 students. A survey called Epistemologies about the Credibility of…

Fata-Hartley, Cori – Journal of College Science Teaching, 2011
Many college science educators have moved away from the traditional lecture format and toward learner-centered classroom environments. Yet many of us struggle to cover large content loads, reverting at times to rote memorization. This paper suggests rote memorization simply does not work and students must be actively engaged to learn. (Contains 1…

Quinn, Frances; Pegg, John; Panizzon, Debra – International Journal of Science Education, 2009
Meiosis is a biological concept that is both complex and important for students to learn. This study aims to explore first-year biology students' explanations of the process of meiosis, using an explicit theoretical framework provided by the Structure of the Observed Learning Outcome (SOLO) model. The research was based on responses of 334…

Montes, Ingrid; Padilla, Adriana; Maldonado, Atenaida; Negretti, Solymar – Journal of Chemical Education, 2009
For many years, ethical misconduct has been long endured and difficult to address in the scientific community. To educate students about ethical misconduct in science, case studies were used in an ethics discussion board for a class group project. The objectives aimed to (i) familiarize students with the term "ethical misconduct", particularly in…

O'Neill, Angie; Birol, Gülnur; Pollock, Carol – Canadian Journal for the Scholarship of Teaching and Learning, 2010
The objectives of this study were to investigate the alignment of exam questions with course learning outcomes in a first year biology majors course, to examine gaps and overlaps in assessment of content amongst the sections of the course, and to use this information to provide feedback to the teaching team to further improve the course. Our…

Domin, Daniel S.; Al-Masum, Mohammad; Mensah, John – Chemistry Education Research and Practice, 2008
Categorization is a fundamental psychological ability necessary for problem solving and many other higher-level cognitive tasks. In organic chemistry, students must establish groupings of different chemical compounds in order not only to solve problems, but also to understand course content. Classic models of categorization emphasize similarity as…

Prokop, Pavol; Rodak, Rastislav – EURASIA Journal of Mathematics, Science & Technology Education, 2009
A pupil's ability to identify common organisms is necessary for acquiring further knowledge of biology. We investigated how pupils were able to identify 25 bird species following their song, growth habits, or both features presented simultaneously. Just about 19% of birds were successfully identified by song, about 39% by growth habit, and 45% of…

Morgenstern, Mark; Meyer, Sally; Whitten, Barbara; Reuer, Matt – Journal of College Science Teaching, 2008
At Colorado College, the energy retrofit of a building is used as a service-learning research project to teach physics and chemistry in a variety of courses. In introductory courses for nonscience majors, the project helps students appreciate the scientific method and quantitative reasoning. Within the physical-chemistry course, students see that…
