Recent efforts to reform science education have strongly emphasized the understanding of the nature of science (NOS) as important to achieving broader scientific literacy. Despite the realization that students' understanding of NOS is important, there is a gap between research and practice. In order to teach NOS effectively in pre-college or…

Attention to inquiry-based teaching practices has surfaced as one vehicle for supporting the development of critical thinking skills in science classrooms (Achieve Inc., 2013). Despite the endless dialogue, professional development, and standards to support the teaching approach, in practice, inquiry presents teachers with a great challenge. In…

This study examines the effectiveness of pre-laboratory presentations in an undergraduate general chemistry laboratory using two different modes of delivery: a traditional lecture versus an in-class video presentation. It was anticipated that implementation of videos could result in improved laboratory efficiency, safety, and necessary technical…

An online curriculum about biological evolution was designed according to the "Promoting Evidentiary Reasoning and Self-Regulation Online" (PERSON) theoretical framework to support evidentiary reasoning and self-regulation. An efficacy study was conducted with 83 suburban high school biology students using design-based research methods.…

There is a growing body of literature emphasizing the use of the schoolyard as a teaching tool, however there is limited research that investigates how to support the development of schoolyard pedagogy. Plains Public Schools is home to 17 elementary schools, 12 of which include one or more features of an enhanced schoolyard, such as garden beds.…

For years science curriculum reformers have bemoaned curricula that are "a mile wide and an inch deep." The tendency for high school science to be "[content]-dominate and textbook centered" leads to science courses bloated with facts and equations at the expense of a deep understanding of science as a process and way of knowing…

This study evaluates the effectiveness of a newly developed educational framework for enhancing scientific literacy in rural high school classrooms. The Confluence Approach (TCA) is a curriculum aligned to the Next Generation Science Standards (NGSS) that utilizes a combination of project-based learning (PrBL) and place-based education (PlBE). TCA…

This study examined the impact of microteaching experiences of preservice elementary teachers enrolled in a science teaching methods course. The microteaching lessons targeted the physical science concepts represented in the Texas Educational Agency's exam for early childhood through sixth grade teacher certification. The results of this study…

Curricular reforms in science education represent an opportunity for changes in instructional approaches with the intent of making learning and teaching more meaningful and effective. While beginning teachers may receive instruction on pedagogy aligned with adopted reforms, veteran teachers need support and development to implement instruction…

The present study elaborates on a domain-specific approach to NOS (Nature Of Science) and employs a NOTSs (Nature Of The Sciences) agenda to investigate how Greek in-service physics teachers understand the unique features of school physics and biology. Our theoretical framework focuses on the notion of worldview and important differences that…

The purpose of this exploratory qualitative study was to investigate prospective elementary teachers' conceptual understanding of buoyancy. Specifically, the study aimed to identify the scientifically accepted conceptions, and misconceptions that preservice teachers hold about buoyancy using an instructional intervention. Presently, there is a gap…

Combined three-dimensional, haptic-enabled, virtual reality (3D HE VR) systems allow students to actively engage and explore various science concepts by leveraging user-friendly and immersive interfaces. Successful implementation of these learning tools in science classrooms hinges upon teachers' perceptions of the technology's potential as a…

Many researchers argue that science, technology, engineering and math (STEM) instruction contribute to the national economy and educators attempt to develop integrated instructional programs. In the current study, the effect of a problem-based STEM activity on students' attitudes, career perceptions and career interests was investigated by using…

A project-based engineering education unit was implemented in a primary school in Cambodia. An effectiveness study was conducted to investigate students' attitudes and expectations of engineering as a profession and students' self-perceived 21st century skills. The findings revealed that prior to the curriculum implementation both male and female…

This study compared the effects of Individualised Instructional Strategy (IIS) and Cooperative Learning Instructional Strategy (CLIS) on male and female senior secondary school students' academic achievement in Organic Chemistry. The study was guided by 2 research questions and 3 null hypotheses. The design was quasi-experimental. The population…
