The rise of social media platforms and subsequent lack of traditional gatekeeping mechanisms have enabled the proliferation of scientific disinformation. Users attempting to properly evaluate scientific information and disinformation are immensely obstructed by media communication mechanisms such as filter bubbles and echo chambers. Given the…

The study investigated the influence of a connected learning approach for explicit nature of science (NOS) instruction and explicit argumentation instruction, in comparison with a non-connected approach, on students' NOS conceptions and argumentation skills. Participants comprised 42 students enrolled in two sections of grade 10 that were randomly…

Design-based learning is considered a powerful way to help students apply and develop understanding of science concepts, but research has shown that the success of this approach is not a given. Examining students' understanding of science concepts in various design-based learning contexts has thus continued to be an important field of research. To…

Learning progressions (LPs) serve as frameworks for understanding the level of complexity of students' ideas within a domain. Multifaceted LPs contain multiple interrelated constructs where increased knowledge in one construct may increase knowledge of a separate construct. While it is challenging to identify and test these contingencies between…

Gender gaps in STEM fields have been studied for a long time, and the primary focus has been on the relationship among social support (parents and teachers), STEM beliefs (STEM interest belief, self-efficacy belief, and value belief), and STEM career expectations. Framed in Expectancy-Value Models, this article aimed to explore how social support…

This study evaluates the use of an open-ended question to determine students' knowledge structure on the topic of galvanic cells. The open-ended question was developed and administered to 163 Grade 10 students who had earlier completed a course on electrochemistry. Students' responses were marked as well as coded on the basis of the fields…

Providing scientific explanations for natural phenomena is a fundamental aim of science; therefore, scientific explanation has been selected as one of the key practices in science education policy documents around the world. To further elaborate on existing educational frameworks of scientific explanation in K-12, we propose a learning progression…

It is a widely held view that students' epistemic beliefs influence the way they think and learn in a given context, however, in the science learning context, the relationship between sophisticated epistemic beliefs and success in scientific practice is sometimes ambiguous. Taking this inconsistency as a point of departure, we examined the…

The purpose of this study was to explore high school students' ideas regarding two theoretical scientific models, either electron cloud or sodium chloride crystal, in the context of active learning in small groups. Conversations among peers regarding these models took place during two types of active learning activities: small-group discussion and…

Research on the design of learning environments for K-12 science education has been informed by two bodies of literature: inquiry-based science and Constructionism. Inquiry-based science has emphasized engagement in activities that reflect authentic scientific practices. Constructionism has focused on designing intuitively accessible authoring…

This instrumental case study examines how secondary biology teachers in a professional learning community (PLC) negotiated the meaning of the "Next Generation Science Standards" ("NGSS") in a year-long process of redesigning their curriculum. The PLC consisted of six biology teachers, five females and one male, who co-planned…

Due to apartheid policies, Black African learners in South Africa have been severely disadvantaged in school science. Despite policy changes to redress these historical imbalances, Black African learners continue to underperform in science. Previous research has identified motivation as a key factor that impacts performance. Achievement goal…

The aim of the present study is to enable future studies into students' attitudes toward science, and related constructs, by developing and validating an instrument suitable for cross-sectional designs. Following a thorough review of the literature it was determined that many extant instruments included design aspects that appeared to be limited…

This paper examines students' achievement and interest and the extent to which they are predicted by teacher knowledge and motivation. Student achievement and interest are both considered desirable outcomes of school instruction. Teacher pedagogical content knowledge has been identified a major predictor of student achievement in previous…

While the majority of published research on conceptual change has focused on how misconceptions can be abandoned or modified, some recent research findings support the hypothesis that acquired scientific knowledge does not necessarily erase or alter initial non-scientific knowledge but rather coexists with it. In keeping with this…
