COVID-19 is the first global pandemic in the age of the internet and the world has collectively documented the virus's spread, offering a unique opportunity to study both the virus and the streams related to COVID-19, on topics from testing access to income to race. They develop their own research question to investigate the relationship between…

Rehearsal is an increasingly important teacher education pedagogy. We explore how 3 science teacher educators thought about and used pauses within rehearsals to support secondary science teacher candidates in learning to facilitate sense-making discussions. Video data indicated that the most common purposes for pausing a rehearsal were to provide…

Making decisions about the production and use of chemical substances is of central importance in many fields. In this study, a research team comprising teachers and educational researchers collaborated in collecting and analyzing cognitive interviews with students from 8th grade through first-year university general chemistry in an effort to map…

This study, part of a series investigating students' use of online tools to assess problem solving, uses eye-tracking hardware and software to explore the effect of problem difficulty and cognitive processes when students solve gas law word problems. Eye movements are indices of cognition; eye-tracking data typically include the location,…

In this article we report the influence of contextual factors on mathematics and science teachers' reasoning in risk-based decision-making. We examine previous research that presents judgments of risk as being subjectively influenced by contextual factors and other research that explores the role of context in mathematical problem-solving. Our own…

Given the current striving for "sustainability" and the corresponding paradigms shift in science, technology, R&D, environment perception, economy and politics; e.g., from unlimited growth-to-sustainable development, correction-to-prevention and passive consumption of "goods", culture and education--to active participation,…

Argues for a decision-making-oriented science and technology curriculum for secondary school students which should: (1) expose students to open-ended problems within their natural setting; (2) provide students with real decision-making situations; and (3) involve students in scientific/technological social actions (in community institutions or…

Suggests introducing values clarification into the classroom as a way to help students learn to make value judgements on contemporary issues. (BR)

Discusses guided design teaching method, applications in secondary/higher education, and the formation of a center to foster guided design as a viable instructional strategy. Guided design course activities are organized around the solution of open-ended problems to provide for the systematic development of decision-making skills. (Author/JN)

Described is a cost-effectiveness analysis applied to the question of the probable impact of 69 actions advocated for improving science education. The major objectives and the 11 categories of interventions are discussed in regard to effective schools and implementing educational change. (KR)

Determined was the effect that cooperative groups heterogeneously based on proportional reasoning ability have on problem solving in regular and honors high school chemistry. Characteristics of successful and unsuccessful problem solvers individually and in groups are discussed. (KR)

Discusses a unit on nuclear technology which is taught in a physics class. Explains the unit design, implementation process, demonstrations used, and topics of discussion that include light and optics, naturally and artificially produced sources of radioactivity, nuclear equations, isotopes and half-lives, and power-generating nuclear reactors.…

This study describes the rationale and activities developed and tested by a project in Israel entitled Biology Critical Thinking (BCT). The BCT project aims at developing a pool of activities that can be incorporated within the regular course of study without investing too much extra time. The purposes of the study are: (1) to present the…

The perspective of biotechnology and its development in the K-12 technology education curriculum are described. The content curriculum development and implications for activities are discussed. The difference between a curriculum focused on the activities of industry compared to one that addresses technology as it pervades all human endeavors is…

An interdisciplinary robotics project undertaken by students is described. The students acted as designers, innovators, and the engineers in designing a dancing robot. The origin of the problem, designing of the mechanical frame, pneumatics, digitized sound, and problems with the design are discussed. (KR)
