In an effort to deepen learning in K-12 science classrooms, there has been a national movement to integrate computational thinking (CT). The purpose of this phenomenographic study was to understand teachers' perceptions of the function and usefulness of a task analysis and a decision tree tool designed to help them with integration. Teachers…

Background: Data visualizations transform data into visual representations such as graphs, diagrams, charts and so forth, and enable inquiries and decision-making in many professional fields, as well as in public and economic areas. How students' data visualization literacy (DVL), including constructing, comprehending, and utilizing adequate data…

Over the last few years, Norway's lower secondary education has increasingly integrated one device for each student, reflecting broader technological trends in the Western world. To plan for learning and assessment in one-to-one classrooms, this article advocates for an ecological approach by elaborating on the term "educational…

To extend the existing research examining multiple text comprehension and its assessment, we developed a verification task approach to assessing of information that was "explicitly" and "implicitly" presented "within" and across nine texts. A nonparametric form of signal detection theory was used to analyse the…

Mendelian genetics are essential for students seeking to comprehend the complexities of inheritance; although fundamental, these biology concepts are difficult for students to understand. This study examined the effectiveness of task-based learning (TBL) in enhancing the students' conceptual understanding of the Patterns of Mendelian Genetics. A…

Assessing students' conceptions related to independence of events and determining probabilities from a sample space has been the focus of research in probability education for over 40 years. While we know a lot from past studies about predictable ways students may reason with well-known tasks, developing a diagnostic assessment that can be used by…

Research on first language (L1) attrition typically focuses on immigrant populations in their second language (L2) environment, yet we know comparably little about L1 attrition in the L1 setting. This study used two lexical tasks to test L1 attrition, a time-sensitive word decision task and a video retelling. Chinese teachers of English vs.…

We implemented a STEM task that highlights the engineering cycle and engages students in productive struggle. Students problem solved in productive ways and saw tangible benefits of revising their work to achieve mathematical goals.

While many studies of monitoring accuracy have been conducted with college students, less is known about middle school students' monitoring accuracy, especially in Asian countries. Prior research also found discrepancies in students' monitoring accuracy between Western and Asian cultures. To understand and support Chinese middle school students'…

This study examines teachers' justifications for addressing unplanned controversial issues in the classroom. It builds on the premise that controversial issues arise unexpectedly in the classroom context and that some teachers actively choose to address such issues rather than avoid them. Through a series of semi-structured interviews with…

The goal of this study was to determine the effect of setting a delay between reading a text and answering comprehension questions on "when"-to-search and "what"-to-search decisions in a task-oriented reading environment. Fifty-five eighth-grade students were randomly divided into two groups. One group read one text, answered…

This study employed a multisite design to investigate the differential impact of deductive and guided inductive instruction for second language (L2) grammar development in ecologically valid classroom contexts. Students (n = 138) from eight intact third-year L2 Spanish classes in three public high schools in the United States received deductive…

The proposed revisions to the "Australian Curriculum: Mathematics" highlight the importance of learning to mathematise, problem-solve and reason in real world contexts, including financial contexts. Through the Economics + Maths = Financial Capability research project, the authors have been imagining fresh ideas for connecting the…

Previous work suggests that adolescents are still refining acoustic-phonetic cue use in clear-speech perception. This study shows adolescents' immature perception of reduced speech, in which speech sounds are naturally deleted and merged within and across words. German adults and 16-year-olds listened to either German reduced or unreduced (few or…

This study investigates the acquisition of null subjects by Mandarin Chinese native speakers ('Chinese NSs' hereafter), with different levels of L2 English proficiency, at initial stages of L3 Italian acquisition. The aim is to find out if, when acquiring Italian null subjects, Chinese NSs resort to their L1, which, like the L3, allows null…
