In the face of an increasingly severe global climate change situation, carbon neutrality initiatives have been included in the development action plans of many countries around the world. The carbon neutrality vision will also accelerate the revolution in the energy systems of countries around the world, injecting new vitality into the upgrading…

Problem solving is a valuable skill in the science classroom. Students often use a variety of inquiry strategies to identify problems and their implications; develop action plans; locate relevant sources, information, and data; and formulate solutions. Problem solving is a logical, analytical, and sometimes creative process. The less tangible,…

Incorporating computer-simulation modelling into project-based learning may be effective but requires careful planning and implementation. Teachers, especially, need pedagogical content knowledge which refers to knowledge about how students learn from materials infused with technology. This study suggests that students learn best by actively…

Outlines and illustrates the Dartmouth approach to developing a science project. This problem-solving approach, promoted by the Thayer School of Engineering at Dartmouth College, helps teachers in guiding students in all phases of project work. (JRH)

Reviews approaches taken in meeting the design requirements in engineering programs. Highlights the value and applications of student involvement in design projects. Explains the features of an engineering case and advocates their use as an alternative or supplement to design projects. (ML)

Approaches children's learning in learning science based on skilled observation by professional teachers, rather than on tests devised by outside agencies. (Editor/RK)

Activities used to teach optics to fifth and sixth graders are presented. Moon phases and solar and lunar eclipses are included. (SA)

Discusses modifications of the usual lecture approach for a environmental geology course by including class discussion, class projects, and group projects which are designed to help students see the relevance of geology to their lives. Author claims that in this interactive approach both instructor and students become more actively involved in the…

Outlines the evolution of thinking and the development of materials related to the biological component of the Science Education Project. Examines the context of the project within Southern African society and its relationship to curriculum development theory. Discusses possible models for the dissemination of knowledge. (RT)

Describes an extended problem-solving activity utilizing drift-bottles that encourages students to deduce probable and great-circle drift-bottle routes, to use logic based on unit calculations, and to estimate the distance traveled and the minimum velocity of these drift-bottles. Includes materials needed, learning objectives, procedures,…

Discusses a child-centered science project in which first-grade students integrate design drawing, construction, mathematics, and language arts to solve engineering problems related to constructing robots. Describes the construction of the robots, follow-up activities, and educational research that supports this approach to teaching. (10…

The Invent America program addresses the need to provide K-8 students with opportunities to learn critical and creative thinking skills through the process of inventing. Students apply problem-solving skills as they turn their own creative ideas into inventions. It is an effort to integrate the curriculum, help students synthesize knowledge, and…

The purpose of this research was to describe how self-efficacy affects the development and science achievement of practicing teachers after their participation in a half day long hands-on science lesson provided by the Science on Wheels project. The 42 practicing K-8 teachers were from eight different counties located in a rural mid-eastern state.…

Presents information in brief on changing priorities in science education. Cites three categories of aims for science, traits of underachievers, and the processes of science. Includes reflections on the Salter's GCSE Scheme of Assessment, the integration of science and drama, and a historical perspective of practical work in school science. (RT)

Describes a contest where sixth-grade students observe the results of a week of planning, folding, testing, and comparing their best paper frog designs and hopping techniques. This integrated unit helps children unleash their imaginations and develop problem-solving skills. (PR)
