Informal best fit lines frequently appear in school curricula. Previous research collectively illustrates that the adjective informal does not translate to cognitive simplicity. Using existing literature, we create a hypothetical framework of cognitive processes associated with studying informal best fit lines. We refine the framework using data…

Students' mental models of diffusion in a gas phase solution were studied through the use of the Structure and Motion of Matter (SAMM) survey. This survey permits identification of categories of ways students think about the structure of the gaseous solute and solvent, the origin of motion of gas particles, and trajectories of solute particles in…

International trended assessments have long attempted to provide instructional information to educational researchers and classroom teachers. Studies have shown that traditional methods of item analysis have not provided specific information that can be directly applicable to improve student performance. To this end, cognitive diagnosis models…

Research on morphological awareness has shown that it contributes to literacy outcomes. However, because of the way morphological awareness is traditionally measured, there is speculation that tasks may reflect cognitive flexibility, working memory, or some other type of executive processing, versus awareness of morphology. Further complicating…

Using qualitative methods and a case study design, the perceptions and writing processes of three African-American eighth grade males were explored. Data were derived from semi-structured and informal interviews, and document analysis. The study concluded that the perceptions of the three participants' writing processes did not adhere to the steps…

The application of mathematics to real-world problems is moving more and more in the focus of attention of mathematics education; however, many learners experience huge difficulties in relating "pure" mathematics to everyday contents. In order to solve "modeling problems", it is first necessary to find a transition from a…

The purpose of the current study was to understand the association between bullying experiences (i.e., bullying, victimization, and defending) and social, emotional, and cognitive factors. The social factor was social skills (i.e., empathy, assertion, cooperation, responsibility); the emotional factor was emotional difficulties (i.e., personal…

In recent years, science education has placed increasing importance on learners' mastery of scientific reasoning. This growing emphasis presents a challenge for both developers and users of assessments. We report on our effort around the conceptualization, development, and testing the validity of an assessment of students' ability to reason around…

Decision making about socioscientific issues is an important aspect of modern science education worldwide. Among the many topics that represent socioscientific issues, issues relating to the sustainable development of our environment are one crucial topic. However, difficulties exist with respect to the assessment of teaching outcomes related to…

As the ongoing national indicator of what American students know and can do, the National Assessment of Educational Progress (NAEP) in Reading regularly collects achievement information on representative samples of students in grades 4, 8, and 12. Through "The Nation's Report Card," the NAEP Reading Assessment reports how well students…

In this commentary, assumptions about the nature and development of children's false memories as described in a recent article by C. J. Brainerd, V. F. Reyna, and S. J. Ceci (2008) are reviewed. Specifically, questions are raised about what drives the development of false memories in fuzzy-trace theory (FTT). Recent studies that challenge a core…

Women remain underrepresented in science professions. Studies have shown that students are more likely to select careers when they can identify a role model in that career path. Further research has shown that the success of this strategy is enhanced by the use of gender-matched role models. While prior work provides insights into the value of…

This article explores student views on writing as shown by the metaphors they use when asked to reflect on their own writing-to-learn tasks in the science classroom. The study examines the metaphors and metaphoric themes of 97 eighth grade students, discusses how they compare to important theories on writing to learn, and explores how student…

This study examined the features of peer argumentation in middle school students' scientific inquiry. Participants were two boys and six girls in grade 8 of a middle school in Seoul, Korea. Students engaged in open inquiry activities in small groups. Each group prepared the report for peer review and then, during the peer discussion, presented…

Data from a study of learning conducted with 26 seventh and eighth graders are used to show the highly heterogeneous and contingent nature of students' responses to lever problems. A framework is proposed to explain variations in cognitive performance across situations and to critique some of the assumptions underlying assessments. (SLD)
