This study investigates the impact of a professional development programme for teachers that encourages more cognitively challenging, practical, and interactive science lessons. Using a Randomised Controlled Trial, its impact was measured by pupil learning outcomes. Pupils aged 9-10 at 42 primary (elementary) schools in Oxfordshire (England) were…

The goals of the study were (a) to compare the instructional effectiveness of immersive virtual reality (VR) versus a desktop slideshow as media for teaching scientific knowledge, and (b) to examine the efficacy of adding a generative learning strategy to a VR lesson. In Experiment 1, college students viewed a biology lesson about how the human…

A pilot study was conducted on a multimodal educational tool, Peruvian Food Chain Jenga (PFCJ), with 5th-grade students (N = 54) at a public charter school. The goal was to compare the effectiveness of the multimodal tool to a more traditional presentation of the same materials (food chain) using an experimental/control design. Data collection…

The purpose of this work is to study the effectiveness of our introductory mechanics instructions in changing students' misconceptions about Newtonian concepts. We gave the force concept inventory (FCI) test to 341 of our students twice, before and after instructions. The data were analyzed using a method first reported by Martín-Blas "et…

We describe the design and implementation of an undergraduate peer mentor program that can overlay an existing general chemistry laboratory and is designed to improve STEM student retention. For the first four freshman cohorts going through the program, year-to-year retention improved by a four-year average of 20% for students in peer-mentored…

The aim of this study is to design and implement a digital interactive globe system (DIGS), by integrating low-cost equipment to make DIGS cost-effective. DIGS includes a data processing unit, a wireless control unit, an image-capturing unit, a laser emission unit, and a three-dimensional hemispheric body-imaging screen. A quasi-experimental study…

Laboratory capacity is an issue that has plagued education for more than a century. New buildings, late night classes, and virtual laboratories have offered transitory relief at great expense. Missouri University of Science and Technology is employing blended strategies to increase capacity and student success. Blended strategies expand learning…

This report provides information about an interactive computer game named Say My Name that allows high school and undergraduate students to review individually nomenclature of organic compounds in an engaging and fun way by answering up to 600 questions distributed in three difficulty levels. Responses from students and teachers who have played…

Animations of molecular structure and dynamics are repeatedly applied to support student comprehension in the theoretical ideas of chemistry. However, students' understanding the dynamics of the phenomena is directly related to the understanding of teachers as instructors. Therefore, this study aimed to investigate how the features of three…

Computer-based simulations are of particular interest to physics learning because they allow learners to actively manipulate graphical visualizations of complex phenomena. However, learning with simulations requires supportive elements to scaffold learners' activities. Thus, our motivation was to investigate whether direct or indirect…

Understanding the nature of science (NOS) is one of the challenging objectives in science education due, in part, to the complex relationship between religion and science. This study examines how NOS teaching affects the perception of the NOS amongst religious, as compared to secular, students. The participants included 205 religious and secular…

The aim of this study is to determine the effect of activities developed in accordance with PDEODE teaching strategy on students' understanding of the particulate nature of matter. The sample of the study consists of the first grade students who study in the Primary School Teacher Education Program. In order to determine the conceptual change on…

Arachnids are predatory arthropods that are beneficial to humans in many ways, with common examples including spiders and scorpions. Despite the importance of arachnids to global ecosystems, the fear of spiders in specific human groups is well documented. Arachnids are a very diverse class (i.e., Arachnida) encompassing eleven extant orders with…

The Teacher Academy in the Natural Sciences (TANS) provided middle school (U.S. Grades 6-8) teachers (N = 81) with intensive professional development in chemistry, geosciences, and physics through 13 days of face-to-face instruction that was extended with 2 online science modules per discipline. Because we administered online module assessments…

This paper presents a pedagogical experiment with parallel groups through which the effectiveness of the cognitive apprenticeship model of dealing with the teaching topic "Carboxylic acids and their derivatives" was compared with the traditional approach to the elaboration of this topic. This experiment featured the participation of 241…
