Integrating literacy in science and mathematics learning and teaching has been an ongoing endeavour. There are frameworks developed to guide teachers' practices, but little is reported on assessing literacy simultaneously with scientific or mathematical content knowledge. We reviewed the literature on assessing literacy in science and mathematics…

Science learning requires students to build new mental models of imperceptible mechanisms (photosynthesis, circadian rhythms, atmospheric pressure, etc.). Since mechanisms are structurally complex and dynamic, building such mental models requires mentally simulating novel structures, their state changes, and higher-order transformations…

Even though the "Next Generation Science Standards" (NGSS) were released over a decade ago, science is still infrequently taught in early childhood and elementary classrooms. A lack of teacher confidence due to inadequate content knowledge may be a contributing factor, making access to high-quality elementary science methods courses even…

Research on teacher educators' professional learning has gained increasing interest within science education. Curriculum materials have been suggested as a means of supporting "teacher" learning for several decades but have not yet been examined as a potential tool for supporting the learning of "teacher educators." In this…

While recent research has examined students' and teachers' understanding of models and modeling, few studies have focused on how teacher educators can support preservice elementary science teachers in envisioning enriched learning processes and outcomes for their students while engaging in modeling practices. Informed by reflective practices…

Reform efforts in K-12 science education have been gaining pace ever since the introduction of the "Next Generation Science Standards" (NGSS). The new vision calls for reconsidering teacher preparation programs to prepare future teachers who are confident and competent in delivering NGSS-based instruction. This study investigated the…

In this article, we tackle the phenomenon of what seems to be a misunderstanding between science education theory and philosophy of science--one which does not seem to have received any attention in the literature. While there seems to be a consensus within the realm of science education on limiting or altogether denying the explanatory role of…

This study reports on eleven second-year teachers who were all students in the same practice-based secondary science methods courses framed around ambitious science teaching. In this qualitative embedded single case study, we examined if, how, and why novice teachers linked their current critical pedagogical discourses and instruction back to any…

For many years, hegemonic approaches to teaching the nature of science (NOS) have focused mainly on understanding some epistemic (i.e., rational, or cognitive) aspects involved in the construction of science. So, aspects of a non-epistemic (i.e., non-rational, contextual, or extra-scientific) nature have been practically neglected in these…

This study investigates how preservice elementary teachers (PSTs) engage and reflect on two science disciplinary practices: engaging with representations and engaging in evidence-based arguments. In the context of elementary science, teachers blend multiple practices across curricular topics and instruction. However, studies of teachers' use of…

Nitrate is a crucial parameter for assessing water quality, owing to its dual function in ecological systems. These functions can be beneficial or detrimental depending on whether nitrate concentrations are low or high, respectively. The ultraviolet spectrophotometric method (standard as 4500-NO[subscript 3]--B) is a classic method for determining…

A new teaching resource comprised of raw X-ray diffraction data sets from crystallography experiments has been compiled. The aim of this resource is to provide a tool with which to plug the teaching gap between crystals and chemical structures present at various levels of education, as well as providing examples for early stage researchers and…

Orientation is a component of pedagogical content knowledge and represents a general view of teaching and learning science. Science instructors hold orientations to teaching science teachers and orientation can be illustrated by an instructor's purposes and goals for instruction. Due to the central role of the instructors in preparing qualified…

In this paper I demonstrate how zines (pronounced 'zeen', a word that is a contraction of 'magazine') about space science can be theorised as a site of science education at the margins. Through exploring different zines and their potential to create counter-narratives I offer a series of objects that might reshape how we teach and learn about…

Web-based discussion tools have emerged as valuable platforms in teaching and learning chemistry. Despite the increasing use of web-based discussion tools, their effectiveness in enhancing cognitive, social, and teaching aspects of organic chemistry remains underexplored. Therefore, this review aims to address the gap by synthesizing relevant…
