This paper describes how plate tectonics and rock genesis, two topics that are typically addressed separately in secondary Earth science classes, can be taught together as an integrated system. We define the TecRocks Reasoning Framework, developed to support student reasoning about rock formation situated in the context of plate tectonics. We also…

This dissertation is an extended prescription for the inclusion of social justice in high school biology (HSB) curricula. Chapter 1 is context: a review of social injustice (mainly racism) in the US, and the specious scientific justifications for it. Chapter 2 explores how three veteran teachers introduce social justice in HSB classes. A…

Understanding why teachers teach the way they do is important especially in a time of curriculum reforms. Hence, the aim of this research is to unpack the secondary school physical science teachers' beliefs on the purposes and goals of science teaching (PGST) and to check the alignment of their beliefs on PGST with constructivism. A convergent…

This study examines how researchers can better understand the instructional and practical realities of teachers through collective sensemaking. Traditional approaches to curriculum design engage learning models without accounting for the needed flexibility of teachers. This approach has resulted in tension and gatekeeping--inhibiting the…

As part of curriculum reforms, models and modelling (MoMo) are playing an increasingly prominent role in science education. Through a questionnaire study, this paper investigates lower secondary school teachers' (n = 246) perceived practices of, rationales behind, and possibilities for working with MoMo in the context of the revised science…

This empirical study investigates the main features of curricula and contexts that favor or hinder the process of transfer of a teaching-learning sequence (TLS) from the designers' original situation to a host one. The specific research questions addressed were (RQ1) what were the changes made during the process of transfer in the new context?…

The research was carried out through research and development to produce an innovative chemistry laboratory workbook (InoChemLaW) followed by the implementation of the learning package in the teaching of chemistry. The result showed that a standard InoChemLaW has successfully been developed on the topic of Colligative Properties of solutions. The…

Implementation of reform curricula requires teachers to adopt new approaches to teaching. Research has provided promising results about the influence of educative curriculum on teachers' learning and instruction. However, this approach generally focuses on teachers as isolated learners. Using a design-based research approach, the authors developed…

The Learning by Making (LbyM) project is funded by the U.S. Department of Education's Investing in Innovation Fund (i3). As a five-year development project (2014-2018), Sonoma State University (SSU), in partnership with high-need schools and districts, has been developing an innovative, integrated high school Science, Technology, Engineering, and…

The authors describe a vocational training course that was developed to give more than just an overview of how aircraft work, or a course on how to fly. This training course was a half-year course in aviation technology. Powered flight is an area of interest for many students, and the intent of creating a curriculum rich with science, technology,…

Researchers at AAAS and BSCS have developed a six-week unit that aims to help middle school students learn important chemistry ideas that can be used to explain growth and repair in animals and plants. By integrating core physical and life science ideas and engaging students in the science practices of modeling and constructing explanations, the…

The article provides science educators with definitions of inquiry and its levels, relating them to real-world scientific processes. Such an educational shift entails a fundamental cultural change in the epistemology of science learning in schools, shifting it from "instructionism" to social constructivist learning. The highest level of…

In South Africa, the Grade 12 "classes of 2008 and 2009" were the first to write examinations under the revised Life Sciences (Biology) curriculum which focuses on outcomes-based education (OBE). This paper presents an exploration of what students (as learners) considered to be difficult and interesting in Grades 10-12 Life Sciences…

Despite the growing consensus regarding the value of inquiry based teaching and learning, the implementation of such practices continues to be a challenge. The goal of this paper is to present a model for the educational infrastructure that can support the implementation of the Biomind program, which is a new open inquiry program for Israeli…

Papua New Guinea is a young, developing nation, achieving independence in 1975. Industries which can be classified as chemical industries by western standards, are almost non-existent in Papua New Guinea. As yet, most of the raw materials it produces are exported to other countries to be processed or manufactured into useful products. However,…
