This paper explores the integration of STEM activities in teaching and learning, emphasizing the importance of innovative pedagogical approaches in effectively introducing theoretical concepts, such as variables and functions, and merging them with practical applications. Drawing on existing literature, this study investigates the integration of…

To investigate how early elementary science and technology (S&T) education, with hands-on experimentation and inquiry-based learning, impacts pre-service teachers' attitudes and confidence to teach S&T education, we used a cross-sectional survey. Our participants were 27 pre-service teachers enrolled in an Ontario elementary S&T…

New experiments for undergraduate students are needed to stimulate experiential learning in the laboratory while providing valuable training for future career development. Iodine deficiency remains a major public health concern that is monitored by measuring the median urinary iodide concentration of a population. In this context, we have…

This paper describes how future physics teachers' involvement in annual Family Math and Science Day--a public outreach event at the University of British Columbia, Canada--has a potential to transform them as physics demonstration experts and amateur video producers. These science demonstration videos serve as teaching and learning resources not…

Almost all commercial quadrupole ICP-MS instruments use collision/reaction cells to either attenuate spectral interferences or shift the analyte of interest to an interference-free "m/z" (e.g., by O addition). A laboratory practical was developed to introduce the students to the basic operating principles of ICP-MS using a hands-on…

Laboratory sections of university Earth science courses provide hands-on, inquiry-based activities for students in support of lecture and discussion. Here, I compare student conceptual knowledge outcomes of laboratory sections by administering an independent concept inventory at the beginning and end of two courses: one that had a lecture and a…

This study describes the experiences of 10- and 11-year-old students with building science models during a unit on weather. With the teacher, we prepared and gathered materials for the students to use in the building of dynamic physical models demonstrating the key features of the weather concepts they were learning. An important aspect of the…
