In this teaching laboratory, the students are directed in an exercise that involves designing and performing an experiment to determine estrogen's role in regulating delayed implantation (diapause) in female rats. To encourage active participation by the students, a discussion question is provided before the laboratory exercise in which each…

A diagnostic study is presented of the prior experiences, conceptions, and pedagogical valuations of prospective primary teachers (PPTs) about experimental activities (ExA's) in science education. The participants were 121 PPTs who, in small teams, responded to various questions related to ExA. Their responses were analysed interpretively with…

Stars are point-source emitters that are the closest to the definition of a blackbody in comparison to all other similar sources of radiation found in nature. Existing libraries on stellar spectra are thus a valuable resource that can be used to introduce the laws of thermal radiation in a classroom setting. In this article we briefly describe…

In this article, year 6 teacher (ages 10-11) Rebecca Towner-Yates shares a case study where science led the way for learning in her class. Based on her experience, she concludes that science can offer opportunities for children who may otherwise switch off from learning to switch back on. Science can offer the disengaged a path back, a chance for…

In this article we describe a course on science outreach that was developed as part of our college's goal that all students participate in a meaningful community engagement experience. The Science & Community Engagement course provides a way for students with science or science-related majors to learn how to effectively communicate scientific…

Magnetism and its various applications are essential for our daily life and for many technological developments. The term "magnetism" is almost always used as a synonym for ferromagnetism. However, the magnetic properties of the elements of the periodic table indicate that the vast majority of elements are not ferromagnetic, but rather,…

Situational interest is a relatively transient reaction to highly stimulating factors in the immediate environment, whereas individual interest is a relatively long-term preference for a particular subject or activity. It has been proposed that regular experiences of situational interest in a subject may eventually lead to the development of…

The eastern oyster, "Crassostrea virginica," is an ecologically and economically important species in Chesapeake Bay. Oysters are ecologically unique in the Chesapeake Bay because they build a structure known as a bar or reef by attaching to one another over a 45 long period of time. They have been coined the "Ecological Engineers…

Biocatalysis is a fundamental concept in biotechnology. The topic integrates knowledge of several disciplines; therefore, it was included in the course "design and optimization of biological systems" which is offered in the biochemistry curricula. We selected the ciliate tetrahymena as an example of a eukaryotic system with potential for…

There is room for improvement in the amount of active learning that takes place during physiology laboratory exercises. This paper describes a protocol designed to examine the human dive response, with the goal of creating an integrative laboratory experienced focused around improving active learning. The objectives of this laboratory exercise…

Sarah Bearchell is a science presenter and writer working with children and families. She aims to engage her audiences through careful tailoring of activities. She works in mainstream primaries and special educational needs and disabilities (SEND) schools, with visits to science festivals becoming more frequent. Many of the schools she visits and…

In this work we analyze the educational reality of Early Childhood Education classrooms in relation to the teaching of science. A total of 83 students from a fourth-year elementary science teacher training program participated in the study. A 48-item instrument was used to collect data. In general, the results obtained show that sciences are a…

There is an increasing emphasis on fundamental particles, including quarks, in the high school physics classroom. However, many teachers might not feel comfortable teaching particle physics because it is a highly abstract and complex topic, and there are few hands-on activities to help teachers bring it into the classroom. In 2010, a…

Traditionally, human anatomy is taught using cadaveric human or animal specimens, however such materials are not always available or are quite costly. Alternate instructional methods can include software, models, clay models, and illustrations. Unfortunately, while cost effective, these methods lack the ability to demonstrate the "in…

Fidget spinners have become a fixation among school children and adults. Pappas (2017) hails spinners as both a boon to stress relief and a constraint on the ability to focus in persons with Attention-Deficit/Hyperactivity Disorder (ADHD) or autism. Spinners can be a distraction in school classrooms, to the point that many schools have banned…
