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…

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…

This article describes revisions to four of the eight constructs of the Duncan molecular genetics learning progression [Duncan, Rogat, & Yarden, (2009)]. As learning progressions remain hypothetical models until validated by multiple rounds of empirical studies, these revisions are an important step toward validating the progression. Our…

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…

The purpose of this mixed-method study was to investigate the changes in high school students' perceptions of fluency with innovative technologies (IT) and the levels of students' scientific inquiry abilities as a result of engaging students in long-term scientific research projects focusing on community-based environmental issues. Over a span of…

The effects of full-credit semester and all-year timetables on science attitudes and science achievement of grade 10 students was investigated. Findings indicated that students in all-year courses consistently outperformed students in semester courses in the cognitive domain, but there were no differences in the affective domain. (CW)

A 20-item double-Q sort was used to measure differences in perceptions of grades 8, 10, and 12 students (N=215) according to letter grades and sex. Differences in perception according to success were found for both ideal and actual student behavior, while sex differences were not noted. (Author/JN)
