This paper analyzes Sim-Evolution, an educational simulator designed to help teachers presenting three basic principles of the theory of evolution by natural selection (TENS): the trait variation within a population, the heritability of trait variation, and the selective survival based on heritable traits. Sim-Evolution focuses on high school…

This work explores the interface between 3D-printing, material sciences, and microfluidics with electrochemical detection in an undergraduate laboratory. This work includes a module for the characterization and electrochemical analysis of microelectrodes that spans 4 weeks (3 h per week). Laboratory exercises include the fabrication of a…

Prospective elementary teachers may enter their teacher education program having experienced science more as a collection of definitions and facts than in ways that support rich engagement with scientific phenomena. As a result, their visions of themselves as science teachers may not align with the most recent understandings about how to teach…

The annual National Collegiate Soils Contest (NCSC) has long been anecdotally recognized as a beneficial event for participating students to practice soil profile descriptions and landscape interpretations. The objective of this study was to quantify student learning outcomes and to identify how students' perspectives shifted over the course of…

The mechanism maps that guide student instruction in organic chemistry curricula are structural representations of bond-breaking and bond-making events that transform a reactant into a product. For students, these pathways represented by electron pushing formalism (EPF) can be challenging to navigate. For instructors, providing formative feedback…

This paper details a digital technology solution to a problem that arose during a science lesson in an early years class. The teacher used the opportunity to enable the children to apply their knowledge and skills of a software application developed in a recent ICT class. Using the age-appropriate app, the students could communicate their learning…

This convergent mixed-methods study investigated what urban fourth-grade students self-reported for navigating multimodal science books. Reported strategies included general reading processes, clarifying understanding, selecting portions to read, choosing an order to read the text, and interpreting the process in the text. A range of metacognitive…

Students in a mixed majors undergraduate microbiology class often struggle with basic genetics concepts, generating gaps in their overall understanding of genetics. This can be a result of employing the traditional block style of instruction that focuses on teaching skills and concepts one topic at a time. Here I present a simple, yet innovative…

Significant changes in the teaching-learning process have occurred since the appearance of the COVID-19 pandemic caused by the SARS-CoV 2 coronavirus, due to the limited mobility and closure of university education centers. In this context, essential challenges were presented for teachers and students to finish the academic courses by addressing…

Science-related competencies are demanded in many fields, but attracting more students to scientific educations remains a challenge. This paper uses two studies to investigate the value of using Immersive Virtual Reality (IVR) laboratory simulations in science education. In Study 1, 99 (52 male, 47 female) seventh (49) and eighth (50) grade…

It is widely acknowledged that understanding of science is key to becoming global citizens and to embrace technological advancements. Although research suggests that girl's performance in science has improved over the years, there are still concerns about the under-representation of women in science, technology, engineering and mathematics (STEM)…

This article describes the implementation of an activity with a Predict-Observe-Explain (POE) learning cycle to teach the concepts of velocity and acceleration to physics students aged 17-19. The study indicates how the instructor enacted the activity and provides sample student responses and group discussions. The description includes an example…

Although empirical studies have consistently indicated that students commonly struggle to learn and understand the concepts related to reflex actions, few teaching strategies have been developed that specifically address these learning difficulties. This article introduces simple teaching models that simulate the nervous pathways related to the…

Science teachers must sometimes teach outside of their expertise, and this type of teaching assignment is referred to as being out-of-field. Among newly hired teachers, this type of assignment may have a detrimental impact in the development of their instruction. This study explored the classroom instruction of 17 newly hired teachers who were…

Science often takes a back burner to English Language Arts (ELA) and Math. With ELA and Math being tested from early years and school funding relying on each, many teachers are pushed by administrators to spend as much time as possible on those two subjects. During the authors' years as classroom teachers and professional development providers,…
