Yan Yang – Interchange: A Quarterly Review of Education, 2024
Written as a letter to Galileo, an education graduate student narrates from course experiences that deepened her understandings of Galileo and natural and intellectual properties underlying his works. Having taken the Galileo-themed course with Elizabeth Cavicchi at MIT's Edgerton Center in three prior terms, on taking it a fourth time, this…

Calvert, Ryan D.; Crawford, Ciera R.; Running, Cordelia A. – Journal of Food Science Education, 2020
Properly made solutions are critical to the scientific method. However, in various laboratories and collaborative environments, we have noticed a lack of proper technique for making solutions. Instead of measuring the moles of solute then filling up to the needed volume with solvent, we observed many individuals would measure the moles of solute…

Roy, Brandon G.; Ryndock, Eric; Lappas, Courtney M. – Biochemistry and Molecular Biology Education, 2021
The amplification of nucleic acids is a fundamental tool utilized in various scientific disciplines, including Molecular Biology, Immunology, Microbiology, and Genetics. However, due to the time and technology required for traditional polymerase chain reaction and its derivatives, it is not always possible to include such methodologies in…

Verena Petermann; Andreas Vorholzer; Claudia von Aufschnaiter – Journal of Research in Science Teaching, 2025
Science teachers' beliefs about teaching and learning are a vital component of teachers' professional competence and are often assumed to impact classroom practice. To date, these beliefs have been predominantly investigated regarding teaching and learning in general or for a particular science subject (e.g., physics). It remains to be determined…

Piergiovanni, Polly R.; Goundie, David A. – Chemical Engineering Education, 2019
Chemical engineering is a challenging field to explain to first-year students. Food production processes are a safe and accessible way to introduce the students to basic engineering concepts. Modernist cuisine -- using scientific methods and engineering techniques to enhance classical cooking -- was used as a hook to capture the attention of…

Dagher, Zoubeida R.; Erduran, Sibel – Canadian Journal of Science, Mathematics and Technology Education, 2017
The purpose of this commentary on Hodson and Wong's (2017, this issue) article is to clarify the merits of the expanded family resemblance approach (FRA) to science education, briefly alluded to in their article, and to discuss the implications of this approach relative to the question of demarcation they raise. In clarifying the merits of the…

Oelkers, Peter M. – Biochemistry and Molecular Biology Education, 2017
A single semester molecular biology laboratory has been developed in which students design and execute a project examining transcriptional regulation in "Saccharomyces cerevisiae." Three weeks of planning are allocated to developing a hypothesis through literature searches and use of bioinformatics. Common experimental plans address a…

Cybulskis, Viktor J.; Smeltz, Andrew D.; Zvinevich, Yury; Gounder, Rajamani; Delgass, W. Nicholas; Ribeiro, Fabio H. – Chemical Engineering Education, 2016
Understanding catalytic chemistry, collecting and interpreting kinetic data, and operating chemical reactors are critical skills for chemical engineers. This laboratory experiment provides students with a hands-on supplement to a course in chemical kinetics and reaction engineering. The oxidation of methane with a palladium catalyst supported on…

Held, Lubomir – Universal Journal of Educational Research, 2017
Avogadro's conception of the structure of gases was not widely accepted by his contemporaries--probably because the hypothesis was not supported by direct evidence. This problem is rarely addressed in schools. This article discusses the difficulties that accompany the acceptance of new ideas. Such difficulties may be associated with the ways in…

Talavera, Isidoro – Forum on Public Policy Online, 2016
There is a gap between the facts learned in a science course and the higher-cognitive skills of analysis and evaluation necessary for students to secure scientific knowledge and scientific habits of mind. Teaching science is not just about how we do science (i.e., focusing on just "accumulating undigested facts and scientific definitions and…

Li, Ming; Shen, Xiaodong; Zhao, Yan; Hu, Xiaomei; Hu, Fuquan; Rao, Xiancai – Biochemistry and Molecular Biology Education, 2017
Homologous recombination, a central concept in biology, is defined as the exchange of DNA strands between two similar or identical nucleotide sequences. Unfortunately, undergraduate students majoring in biotechnology often experience difficulties in understanding the molecular basis of homologous recombination. In this study, we developed and…

Gikopoulou, Rania – Primary Science, 2017
Rania Gikopoulou is a primary school teacher and post-doctoral researcher at the National and Kapodistrian University of Athens. In this article she describes how her 5th grade class (Age 11) learned about abstract phenomena through models of their microscopic structure.

Dorner, Meredith – American Biology Teacher, 2015
Research shows the importance of active learning, especially within science classes. One way to achieve this goal is to incorporate student-driven projects into the course (e.g., posters). Traditionally, science-poster assignments follow the spirit of the science fair in which a student conducts an experiment and analyzes the results. This article…

Novo, M. Teresa; Casanoves, Marina; Garcia-Vallvé, Santi; Pujadas, Gerard; Mulero, Miquel; Valls, Cristina – Journal of Biological Education, 2016
We present a practical activity focusing on two main goals: to give learners the opportunity to experience how the scientific method works and to increase their knowledge about enzymes in everyday situations. The exercise consists of determining the amylase activity of commercial detergents. The methodology is based on a qualitative assay using a…

Williamson, Ryan P.; Barker, Brent T.; Drammeh, Hamidou; Scott, Jefferson; Lin, Joseph – Biochemistry and Molecular Biology Education, 2014
Bacterial viruses, otherwise known as bacteriophage (or phage), are some of the most abundant viruses found in the environment. They can be easily isolated from water or soil and are ideal for use in laboratory classrooms due to their ease of culture and inherent safety. Here, we describe a series of 10 laboratory exercises where students collect,…
