We investigate a personal response system (PRS) pedagogy for lecture halls that encourages active engagement yet lowers barriers for implementation by eliminating the need to address student requests to make up questions because students must answer (not necessarily correctly) only more than half (greater than or equal 50%) of PRS questions to…

High-quality science assessments are multi-dimensional. They promote disciplinary practices, core ideas, cross-cutting concepts, and science sense-making. In this paper, we investigate the feasibility of using generative artificial intelligence (GenAI), specifically multimodal large language models (MLLMs), to annotate and provide improvement…

Some science subjects are often perceived to be difficult and boring by students due to their nature and the way they are taught. This study sought to check the effectiveness of the technology-enhanced instruction method with comprehensive use of virtual labs and animations in teaching nerve cells' (neurons and glial cells) structures and…

To provide a good understanding of many abstract concepts in the field of electricity above that of their students is often a major challenge for secondary school teachers. Many educational researchers promote conceptual learning as a teaching approach that can help teachers to achieve this goal. In this paper, we present Physlet-based materials…

Based in the tenants of standards-based grading or specifications grading systems, earning digital badges allows students to engage with content until they demonstrate the required knowledge through assessments to earn the badge. Using digital badges to show completion of criteria has gathered attention, but a study involving their use in a…

Educational videos are increasingly used to let students prepare lesson material at home prior to in-class activities in flipped classrooms. The main challenge of this teaching strategy is to stimulate students to watch these videos attentively before going to class. This paper describes the use of questions that pop-up within relatively long…

Model-based reasoning has been introduced as an authentic way of learning science, and many researchers have developed technological tools for learning with models. This paper describes how a model-based tool, "BioLogica"™, was used to facilitate genetics learning in secondary 3-level biology in Singapore. The research team co-designed…

The purpose of this study was to examine the effect of a digitized podcast to deliver read-aloud testing accommodations on mobile devices to students with disabilities and reading difficulties. The total sample for this study included 47 middle school students with reading difficulties. Of the 47 students, 16 were identified as students with…

The landscape of science education is being transformed by the new "Framework for Science Education" (National Research Council, "A framework for K-12 science education: practices, crosscutting concepts, and core ideas." The National Academies Press, Washington, DC, 2012), which emphasizes the centrality of scientific…

This study investigated the effectiveness of a guided inquiry integrated with technology, in terms of female middle-school students' attitudes toward science/scientists and content knowledge regarding selective science concepts (e.g., Greenhouse Effect, Air/Water Quality, Alternative Energy, and Human Health). Thirty-five female students who were…

The Advanced Placement (AP) Descriptive Chemistry Website allows users to practice chemistry problems. This study involved the redesign of the Website using worked examples to enhance learner performance. The population sample for the study includes users (students and teachers) interested in learning descriptive chemistry materials. The users…

The Exploring Florida Science project goals were: (1) increasing content knowledge of secondary science teachers, specifically in topics that are important to the future of the state, and (2) providing secondary science students with digital media for use in project-based learning. A team of instructional designers, educators, scientists, web…
