Explains biosphere troubles due to tropical deforestation. Discusses long term consequences and effects. First published in 1988. (YDS)

Explains the use of a Sun Tower in different activities at elementary grade levels while addressing national and state science standards. Shows the movement and motion of the sun in the sky. Introduces an activity that includes the sun tower in which students observe the changes of shadows every half hour. (YDS)

Makes the case that geologic fieldwork requires more than knowledge of basic skills learned in the standard undergraduate curriculum. Argues that synthesis of the skills into a schema must be done before one can address the kinds of problems that arise when doing field investigations. Argues for the use of descriptive geometry and trigonometry in…

Suggests an integrated approach to make science teaching and learning more effective, interesting and motivating to students. Argues that team teaching by physics and geology departments enables students to learn concepts and principles of physics and apply them to solve geological problems facing the local community. Reports that a typical…

Uses dartboards to represent magnitude-frequency relationships of natural hazards which engage students at different levels of preparation in different contexts, and for different lengths of time. Helps students to mitigate the misconceptions that processes occur periodically by emphasizing the random nature of hazards. Includes 12 references.…

Introduces an entry level mineralogy/igneous petrology course designed for undergraduate students and presents a series of learning activities based on individual and cooperative learning. Includes 18 references. (Author/YDS)

Discusses the issues related to students' alternative conceptions, how these conceptions affect student learning, identification of these conceptions, and teaching methods able to transform students' conceptions into scientific understanding. Includes 20 references. (YDS)

Investigates the effects of cooperative learning instruction versus traditional teaching methods on ninth-grade students' (n=770) earth-science achievement in secondary schools. No significant differences were found between the experimental groups and the control groups on overall achievement, knowledge-level, and comprehension-level test items,…

Points out the potential of the moon as a rich teaching resource for subject areas like astronomy, physics, and biology. Presents historical, scientific, technological, and interesting facts about the moon. Includes suggestions for maximizing student interest and learning about the moon. (YDS)

All interest necessarily links the person with the external environment: the object/s of interest. Research into children's interests is examined in the context of a rapidly-expanding literature which has generated several powerful concepts in recent decades, notably "individual interest", "situational interest" and "topic interest". The first is…

The article describes an activity for the author's fifth-grade students called "build the strongest mountain." To them, it was not a lesson--it was a challenge. To the author, it was an activity that turned a run-of-the-mill Earth science unit into a terrific opportunity for students to demonstrate their knowledge of erosion and develop…

In this extended earth science activity, students create a hands-on model of a volcano to achieve an understanding of volcanic structure, lava flows, formation of lava layers, and the scientific work of archaeologists and geoscientists. During this simulation activity, students have opportunities to learn science as inquiry and the nature of…

Because of the educational importance of mathematics and science, IEA's (International Association for the Evaluation of Educational Achievement) Trends in International Mathematics and Science Study, widely known as TIMSS, is dedicated to providing countries with information to improve teaching and learning in these curriculum areas. Conducted…

Educational researchers have suggested that the tension between the learner-centred and teacher-centred pedagogies represents a real classroom issue that influences teaching and learning. This issue may be particularly significant in East-Asian countries such as Taiwan due to some cultural influences. For example, teacher authority is highly…
