In a sample of 455 Taiwanese upper-secondary school students, latent variable structural equation modeling was used to test hypothesized relationships between beliefs about knowledge in science, beliefs about justification for knowing in science, and justification of knowledge claims concerning science encountered on the Internet. Results…

Scientific expertise and outcomes often give rise to controversy. An educational response that equips students to take part in socioscientific discussions is the teaching of Socially Acute Questions (SAQs). Students engaging with SAQs need to engage with socio scientific reasoning, which involves reasoning with evidence from a variety of fields…

The article argues that science assessment should change from an item-driven to a construct-driven practice and pay more attention to disciplinary scientific reasoning. It investigates assessment scales developed from a novel theoretical rationale, describing scientific reasoning as three fundamental practices (hypothesizing, experimenting, and…

Explanations of the role of analogies in learning science at a cognitive level are made in terms of creating bridges between new information and students' prior knowledge. In this empirical study of learning with analogies in an 11th grade chemistry class, we explore an alternative explanation at the "social" level where analogy shapes…

Using self-generated analogies has been proposed as a method in a constructivist tradition for students to learn about a new subject, by use of what they previously know. We report on a group exercise on using self-generated analogies to make sense of two thermodynamic processes, reversible adiabatic expansion and free adiabatic expansion of an…

Investigates difficulties in thinking about interactions between variables and suggests remedial educational means. Reports that expert thinkers demonstrate thinking about interactions at both an operational and metastrategic level. Lay adults, however, encounter substantial difficulties in drawing valid interaction inferences while engaged in an…

This article explores the conceptual change of students in Grades 10 and 12 in three Australian senior high schools when the teachers included computer multimedia to a greater or lesser extent in their teaching of a genetics course. The study, underpinned by a multidimensional conceptual-change framework, used an interpretive approach and a…

This study describes the multiple analogical models used to introduce and teach Grade 12 chemical equilibrium. We examine the teacher's reasons for using models, explain each model's development during the lessons, and analyze the understandings students derived from the models. A case study approach was used and the data were drawn from the…

Investigated influence of sex-related contextual nature of tasks (male-related, female-related, and content-free tasks) and perceived difficulty of these tasks on logical reasoning of Nigerian high school students (N=70). Results indicated that males scored higher than females on male-related tasks and females scored higher on female-related…

Found grades in science achieved by tenth-grade general science students correlated with their scores on Propositional Logic Test. The students' ability level was consistently related to the pattern of errors they committed on that measure. Mean scores were lowest on a subtest of ability to use the bicondition and implication, higher on the…
