Under the appropriate conditions, oscillatory chemical reactions have the capacity to generate chemical waves and spatial patterns. Among these structures, Turing patterns are a distinct class that, to date, has not been commonly demonstrated in a classroom environment. We present here a novel, practical procedure for the demonstration of Turing…

As the world becomes increasingly rooted in all forms of inequities, so does the need to fight its causatives. This study is concerned with ensuring that science education serves to reinforce gender equity against traditional narratives. We explored the potency of culturo-techno-contextual approach (CTCA) in leveling the playing field while…

The COVID-19 pandemic presented significant challenges for both students and educators, particularly because of the virtualization of classes and the consequent lack of practical sessions following the closure of laboratories and experimental fields in universities. The absence of interaction among students and practical classes led to a…

This case study explores the integration of children's literature in science education, with a focus on engaging preservice teachers in a science methods course to select, locate, design, and implement the integration of children's literature in their instructional practices. Sixty-four elementary preservice teachers in an initial teacher…

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…

The field of biology is becoming increasingly fragmented, and this fragmentation spills over into the ways our students think and learn about biology. Biology education policy documents stress the importance of teaching biology in an integrated manner and call for the biology education research community to establish a unifying paradigm for the…

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…

In this paper, we use the "Family Resemblance Approach" (FRA) as a framework to characterize how scientists view the nature of science (NOS). FRA presents NOS as a "system" that includes clusters or categories of ideas about the cognitive-epistemic and social-institutional aspects of science. For example, the…

Learning progressions (LPs) are cognitive models that describe the development of scientific knowledge and practices in students. They are constructed based on learning theories and student data. Scholars have advocated for using LPs to align curriculum, instruction, and assessment into a coherent system, and by doing so, promote productive…

The Next Generation Science Standards (NGSS) engage students in the epistemic, or knowledge building, components of science through three-dimensional learning. Each scientific domain has its own epistemic aspects that result from different social groups going about science in different ways to conceptualize different bodies of knowledge; education…

Functional group analysis is an essential part of the curriculum for identifying unknown organic compounds. However, traditional methods of analyzing functional groups use excess reagents and generate a large amount of waste material that is difficult to dispose of. This work is focused on alternative methods for detecting functional groups such…

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…

The importance of models and modeling in science education is well-recognized, yet there exists significant polysemy among these terms within the literature. This ambiguity often leads to confusion, particularly regarding whether modeling represents an expected student performance, an instructional strategy to promote such performance, or both.…
