Responses of 322 university sophomores (education majors) on an evolution problem "How could the bat have evolved wings?" are analyzed and classified. Concludes that misunderstandings are logical. (PR)

Beginning physics students (n=42) were constrained to analyze mechanics problems according to a hierarchical scheme that integrated concepts, principles, and procedures. After five one-hour sessions, students increased their reliance on the use of principles in categorizing problems according to similarity of solution and in writing qualitative…

Describes problems in teaching problem solving and summarizes research in this area. Presents Guided Design or Guided Decision Making as a problem-solving approach in which groups of students work their way through a model of the problem-solving process as they wrestle with a discipline-specific situation. (PR)

Describes a class activity where individual students ask the teacher "yes and no" questions to find the amount of force the bicep uses to lift a 1 kilogram mass. (PR)

Argues that science students often perceive physical events, the nature of scientific knowledge, and the nature of learning processes in different ways from science teachers and scientists, and that science teachers need to account for these differences in planning their science teaching. Contains 40 references. (WRM)

Presents a theory of learning in science based on students deriving conceptual linkages among multiple models which represent physical phenomena at different levels of abstraction. Finds that high school students who were exposed to derivational links among three models for basic electricity performed better when solving both qualitative and…

Describes a simple, small-scale experiment that can be applied at any stage in a chemistry course, including acid-base reactions, solubility, reaction rates, equilibrium, and problem solving. (WRM)

Assesses students' learning of evolution by natural selection within four different sections of an introductory biology course where each section used a different combination of curricular materials and instruction. Reports that comparisons between sections support the use of paired problem-solving instructional strategy in conjunction with the…

Discusses the benefits of having students do research with other students and having teachers do research with other teachers. Recommends connecting topics for the investigative process with issues from students' real life experiences. (DDR)

Describes development of an Experimental Astronomy Curriculum or Thinking Journey, based on a combination of Constructivism and Mediated Learning Experience. Results indicated the effectiveness of the Thinking Journey in promoting a process of positive change in the students' conceptualization of Earth, improving their knowledge of astronomy,…

Baylor College of Medicine, a Houston-area school district, and the Harris County Department of Education implemented a real-world science-instruction model in all district K-4 classrooms. The 7-year Environment as a Context for Learning Science (ECOS) program provokes student interest by centering on locally relevant environmental issues. (9…

On the eastern edge of the Cascade Mountain range in Washington State, high school biology students have a unique opportunity to study the elusive cougar ("Felis concolor"), a large cat native to the area. Nestled in the Cascade foothills is the city of Cle Elum, a small rural community that is expected to soon experience considerable…

This study reports on a multi-year effort to create and evaluate cognitive-based curricular materials for secondary school science classrooms. A team of secondary teachers, educational researchers, and academic biomedical engineers developed a series of curriculum units that are based in biomedical engineering for secondary level students in…

Student success in solving physics problems is related to the representational format of the problem. We study student representational competence in two large-lecture algebra-based introductory university physics courses with approximately 600 participants total. We examined student performance on homework problems given in four different…

The National Inquiry Standard for Science Education Preparation requires science teachers to introduce students to scientific inquiry to solve problems by various methods, including active learning in a collaborative environment. In order for science teachers to comply with this inquiry standard, activities must be designed for students to…
