Most chemistry instruction and assessment lie in the symbolic domain of Johnstone's representational levels, despite years of chemistry education researchers calling for increased emphasis to be placed on the molecular or particulate level of chemistry. Without a deep understanding of the particulate nature of matter and molecular-level…

A new generation of science curriculum materials is being developed and made widely available across K-12. These materials, along with their associated professional learning, are expected to play a pivotal role in transforming science instruction to meet the vision of A Framework for K-12 Science Education and the performance expectations of the…

Previous studies have demonstrated that the socio-scientific issue approach (SIA) and design thinking (DT) can inspire creative thinking in science learning. However, the way in which the integration of SIA and DT fosters creative thinking in entrepreneurship (CTE) among rural secondary school students during science learning remains unclear. To…

Chinese 2017 General High School Physics Curriculum Standards explicitly include understanding the nature of science (NOS) as core literacy for students. History, philosophy of science, and sociology of science (HPSS) education is an important way to promote students' understanding of the nature of science. In this context, this study analyzed the…

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…

In order to prepare Rwandan citizens for a competitive world, a competence-based curriculum (CBC) has been implemented since 2016. The problem addressed by this study is "under which conditions will the implementation of the intended science curriculum be realised in classroom". Framed by the Rogan and Grayson theory of curriculum…

In this study, which is aimed to investigate the balance principle of the secondary school science curriculum, a case study, one of the qualitative research methods, was employed. In the study, which was conducted by using case design, data analysis was performed by using teacher opinions, observation, and document analysis. The weighted kappa…

The importance of integrating effective teaching strategies in Professional Development (PD) programs for Educational Robotics (ER)-based Science Technology Engineering and Mathematics (STEM) education is increasingly recognized. However, we need to add to the growing body of studies on comprehensive instructional approaches for teaching robotics…

"Citizen science" popularly refers to a participatory approach in which lay persons voluntarily contribute data toward scientific enterprise. Although citizen science may provide unique opportunities for pre-college students to engage in data-intensive science practices, little is known about whether or how citizen science interacts with…

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…

The overarching goal of this paper is to illustrate the interplay between theory, design principles, and curriculum (meant broadly, to include both written and enacted curriculum). This dialogue is illustrated in the context of the design and implementation of a particular curricular unit on thermodynamics intended for advanced secondary students…

Culturally Relevant Education (CRE) focuses on the design of curricular materials that strengthen students' cultural identities while teaching classroom content and science practices. While examples of CRE in science continue to grow, the identities and cultures of the designers are often different from those of the students and communities in…

In a historical moment in which Artificial Intelligence and machine learning have become within everyone's reach, science education needs to find new ways to foster "AI literacy." Since the AI revolution is not only a matter of having introduced extremely performant tools but has been determining a radical change in how we conceive and…

A new science curriculum, with a significant emphasis on modelling, was recently adopted in Danish lower secondary education. The theoretical intentions behind the new curriculum include substantial changes to how teachers should address models and modelling in their practice. The purpose of this study is to analyse the alignment between the…

There are many reasons students fail to achieve in STEM related fields post high school. For example, students may spend too much time receiving teacher centered lessons that focus primarily on vocabulary building and concept recognition. These lessons may not necessarily promote understanding or encourage students to learn other skills than…
