A priority of agricultural teacher education programs is to develop technically competent, prepared school-based agricultural education (SBAE) teachers. SBAE teachers should be knowledgeable in various agricultural subject matter, such as agricultural mechanics. Using Roberts and Ball's (2009) Content-based Model for Teaching Agriculture as the…

This study investigated the perceptions and quality of argumentative and summary writing of the Pre-service Science Teachers (PSTs) who participated in a knowledge generation approach to learning, which is known as the SWH approach, and who had had experience with it across different time periods. A total of 41 PSTs were divided into three groups…

Physics lab instructors were forced to adapt their courses in 2020 due to the COVID-19 pandemic. We investigate the impact these changes had on student views towards experimental physics as measured by the Colorado Learning Attitudes about Science Survey for Experimental Physics (E-CLASS). Analysis of the responses from over 1600 students in both…

The purpose of this study is to investigate the self-efficacy levels of pre-service science teachers who participated in a workshop about physical laboratory implementations supported by digital simulations and also to determine their views on digital simulations. For this purpose, a 6-week workshop was designed based on a digital simulation…

Students in advanced undergraduate chemistry laboratories are required to undertake a wide range of complex and multistep syntheses and analytical procedures, and prospective employers of chemistry graduates seek students with proven skills in these areas. Our approach has been to use video resources which are made available to students both ahead…

With the abrupt nationwide lockdown caused by the COVID-19 pandemic, many universities suspended face-to-face activities. Some of them decided to continue their academic courses, adapting traditional approaches to online learning. An important challenge was to deliver programming labs over the Internet without important methodological changes,…

General chemistry students need to understand the concept of intermolecular forces and use them to predict the properties of materials. To do this, they must create symbolic representations of molecules, relate these to physical observations, and explain them using submicroscopic theoretical constructs. When these concepts are taught separately,…

This article examines how to increase access to undergraduate research within the interdisciplinary field of writing studies. Drawing on experiences with this effort, the authors argue that students need a more diverse range of opportunities to participate in undergraduate research. The article presents and analyzes three case studies of…

This paper presents a thorough method for studying the interference of water waves. The study aimed: (a) to demonstrate the interaction of two coherent waves, which creates interference patterns, and (b) to analyse the interference patterns. Three main tools were employed: a simplified ripple tank to experiment, a smartphone camera to record the…

A Science, Technology, Engineering and Mathematics (STEM) tool is proposed in this manuscript; which consists of an interactive, simple and low-cost computer based simulation and game, with the aim of easing the teaching/learning process regarding the physics concept of projectile motion. The novelty of this proposal relies on the use of a…

In the school year 2020-2021, the COVID-19 pandemic imposed distance learning (in Italian, the DAD acronym is used). Therefore, the Degree Course in Primary Education Sciences of the University of Perugia has proposed an innovative programme for the training of future teachers by developing a distance learning laboratory focusing coding and…

The learning of laboratory skills is essential in science education, but students often get too little individual guidance in this area. Augmented reality (AR) technologies are a promising tool to tackle this challenge and promote students' high-level learning and performance in science laboratories. Thus, the purpose of this study was (1) to…

A chemistry laboratory experiment using everyday items and readily available chemicals is described to introduce advanced high school students and undergraduate college students to porous polymer membranes. In a three-step manufacturing process, a membrane is produced at room temperature. The filtration principle of the membrane is then…

A laboratory experiment in which students study the kinetics of the Viscozyme-L-catalyzed hydrolysis of cellulose and starch comparatively was designed for an upper-division biochemistry laboratory. The main objective of this experiment was to provide an opportunity to perform enhanced enzyme kinetics data analysis using appropriate informatics…

Proteins are involved in nearly every biological process, which makes them of interest to a range of scientists. Previous work has shown that hand-held cameras can be used to determine the concentration of colored analytes in solution, and this paper extends the approach to reactions involving a color change in order to quantify protein…
