This study investigated sixth-grade middle-level students' geometric spatial development by gender and race within and between control and experimental groups at two middle schools as they participated in an Earth/Space unit. The control group utilized a regular Earth/Space curriculum and the experimental group used a National Aeronautics and…

Recognizing the relevance that fieldwork and field trips have in the teaching of geosciences and related learning processes, this study presents two geological fieldwork studies that were established with Portuguese secondary school students. Both studies were focused on geoscience content knowledge, and attempted to increase environmental…

This study investigates critical thinking in a Physical Geography course and illustrates how students can understand physical geography in the context of their world. As a general education science course, most students are in non-science disciplines and feel disconnected from the material. By using exercises that challenge learning and concept…

This study involved examining an instructional unit with regard to its concept content and appropriateness for its target audience. The study attempted to determine (1) what concepts are treated explicitly or implicitly, (2) whether there is a hierarchical conceptual structure within the unit, (3) what level of sophistication is required to…

Presents the results of a survey on volcanism completed by secondary students (N=1000) in Northern Italy. Findings indicate that these students, who live in a non-volcanic area, firmly believe that their area is volcanic. (DDR)

This study evaluates the effectiveness of a mnemonic approach to teaching about the solar system to non-leveled Grade 9 students versus a traditional outline format. A mixture of 54 regular and special education students participated in the control group receiving facts about the solar system through lecture and transparencies and recorded the…

Explains how basic mapping skills are taught in a large lab space using various arrangements of books to portray structural information. Reports an increase in student confidence and ability to synthesize data during field work. (DDR)

Provides a description of a program in Maine that emphasizes the relevance of earth science to students' everyday lives with classroom activities that address real societal issues such as wise management of habitats. Includes two of the activities from the curriculum materials. (DDR)

For many, the dominant model of curriculum development in science includes generating a topic, clarifying science content, identifying activities associated with the topic, and figuring out an assessment. Unfortunately, this approach tends to overemphasize activities and underemphasize mastery of science concepts and the process of scientific…

Presents a weeklong earth science module that allows students to explore the relationships between natural and manufactured materials. Relates rocks and minerals in the earth science curriculum to observations students make in their urban and suburban travels. (DDR)

Describes an educational program that asks students to attempt to prove that the earth is spherical and that it rotates. Presents tips to pique student interest and charts related to sensing the spin, nonrotation notions, flat earth fallacies, evidence that the earth is spherical and rotates, and the role of watersheds in proving that the earth…

Reports a study (n=41) of the effectiveness of in-depth, conceptually integrated instruction delivered via a videodisc program in eliminating children's alternative frameworks in science. This curriculum, which did not directly address alternative frameworks during instruction, changed 92% of the alternative frameworks held by students to…

Uses interviews and a written questionnaire to probe students' ideas on the origin of earth and life on earth. A significant number of commonly held misconceptions were prevalent in the sample (N=493). Provides guidelines to assist learners in challenging existing views. Contains 64 references. (DDR)

Tested Ausubel/Novak hypothesis that primary grade students can learn meaningfully certain aspects of science concepts in the "reception learning" model. Revised audio-tutorial instruction unit on earth based on understanding children's misconceptions; assessed impact of revised units with second graders; and compared results to concept…

Examines congruence between science content structure of instructional materials and students' structural representations before and after science instruction. Eighth-grade science students (N=30) were given concept-structuring tasks before and after studying instructional materials to assess changes in student structural representations.…
