We propose a conceptual framework for STEM education that is centered around justice for minoritized groups. Justice-centered STEM education engages all students in multiple STEM subjects, including data science and computer science, to explain and design solutions to societal challenges disproportionately impacting minoritized groups. We…

The push for STEM has raised the visibility of engineering as a discipline that all students should learn. With the release of the "Framework for K-12 Science Education" and the Next Generation Science Standards (NGSS), engineering now has an official place in the science curriculum. In both the "Framework" and the NGSS,…

Reports on a study conducted to identify cognitive factors associated with differences in predicting problem-solving success among high school biology students. Results indicate that successful prediction depends on several factors, including a subject's procedural and declarative knowledge, stage of cognitive development, and experience in…

Examines ways in which students collaborate to construct, use, and revise conceptual and strategic knowledge as they solve complex genetics problems. Concludes that students used three types of knowledge during model revision: knowledge of genetics, knowledge of the process of model revision, and knowledge of their own problem-solving strategies…

Discusses schematic modeling and describes an experiment in which Lebanese high school and college students participated in problem-solving tutorials that followed a schematic modeling approach. Results indicate that both groups improved significantly in problem-solving performance and the course achievement of students in the college group was…

Performs analysis on a number of articles published between 1985 and 1995 describing experimental research into the effectiveness of a wide variety of teaching strategies for science problem solving. Identifies 22 articles describing 40 experiments that met standards for meta-analysis. Indicates that few of the independent variables were found to…

Explores relationships among school students' (n=189) meaningful learning orientation, reasoning ability and acquisition of meaningful understandings of genetics topics, and ability to solve genetics problems. Results indicate that meaningful learning orientation best predicted students' understanding of genetics interrelationships while reasoning…

Students (233) in five Israeli high schools were tested to determine the relationship of IQ and achievement, attitudes, and manipulative and observational skills in chemistry. Students indicating a desire to pursue science study were found to differ signicantly their non-science oriented couterparts only on cognitive ability measures. (CP)

Explores the relationship of an individual's reliance or nonreliance upon concrete cues in problem solving and performance on a model-based measure of hierarchical classification. Level of cognitive development, as determined by performance on Piaget-type tasks, generally predicted hierarchical classification ability of junior- and senior-high…

Investigates students' mental models of chemical equilibrium using dynamic science assessments. Reports that students at various levels have misconceptions about chemical equilibrium. Involves 10th grade students (n=30) in the study doing a series of hands-on chemical experiments. Focuses on the process of constructing mental models, dynamic…

The purpose of this study was to elucidate the relationship between students' procedural and declarative problem solving associated with one particularly important problem-solving skill, prediction. The results confirm that successful prediction problem solving involve an intricate network of relevant declarative knowledge that is manipulated and…

Uses a constructivist framework in conjunction with an interpretive methodology to investigate the effect of an intervention using the metaphor "learning is constructing" on students' metacognition and learning process. Believes that contextual factors are key determinants of students' propensity towards enhancing their metacognition and…

Compares the problem-solving skills required for solving well-structured problems and ill-structured problems in the context of an open-ended, multimedia problem solving environment in astronomy. Assesses students' abilities in solving these problems with two sets of open-ended questions. Concludes that solving well-structured and ill-structured…

Analyzes students' attempts to answer examination questions involving stoichiometry and chemical equilibrium and reports that the majority of the students do not fully understand either concept. Concludes that the main difficulty with these topics is that they are highly abstract and first taught to students before they have reached the stage of…

Challenges Wilson's 1990 work which, according to the author, bluntly rejected various expert-novice techniques in favor of the classical experimental design. Asserts that, if educators want to study expertise, they should move to understand this expertise in context, for example, in real-life tasks. Argues that research questions not methodology…
