Understanding how geologists conduct fieldwork through analysis of problem solving has significant potential impact on field instruction methods within geology and other science fields. Recent work has highlighted many aspects of fieldwork, but the problem solving behaviors displayed by geologists during fieldwork and the associated cognitive…

Characterizes specific spatial abilities required in geology studies through the examination of the performance of high school students in solving structural geology problems on the geologic spatial ability test (GeoSAT). Concludes that visual penetration ability and the ability to perceive the spatial configuration of the structure are…

Describes a case study of the social construction of knowledge when undergraduate students are engaged in collaborative analysis of repertory grids produced by themselves and their instructor. Results indicate that this approach motivates students to be responsible for their own learning, allows students to communicate their understanding, and…

Investigated: (1) "potent" testing cues that were identified by high-test-anxious (HTA) and low-test-anxious (LTA) undergraduate students (N=133); (2) differences between HTA (N=93) and LTA (N=40) students for frequencies and intensities of responses to testing cues; and (3) differences between HTA and LTA students for attentional…

Presents a model that describes how students reconstruct geological transformations over time. Defines the critical factors influencing reconstructive thinking: (1) the transformation scheme, which influences the other diachronic schemes; (2) knowledge of geological processes; and (3) extracognitive factors. (Author/KHR)

Studies (n=51) inservice school teachers with regard to their orientations toward geoscience phenomena in general and deep time in particular. Aims to identify the nature of idiosyncratic conceptions of deep time and propose a curricular Deep Time Framework for teacher education. (Contains 29 references.) (Author/YDS)

This descriptive study was conducted to (1) measure anxiety levels of geology students (N=49) and earth science students (N=68) about taking these required departmental courses; (2) measure their general anxiety level; and (3) examine factors associated with student anxiety. Results (including those related to sex differences) are reported and…

Students (N=14) in a geomorphology course took an objective geomorphology test, the tree construction task, and the Standardized Concept Structuring Analysis Technique (SConSAT) version of concept mapping. Results suggest that the SConSAT knowledge structure dimensions have moderate to good construct validity. Contains 82 references. (DDR)

Presents a list of 52 earth science concepts in order of their ranking by a panel of earth scientists asked to judge importance for inclusion in the school curriculum. (AL)

Examines vertical transfer in a sequence of three tasks for a conceptual network from geology, attempting to determine whether instruction on earlier tasks in a sequence for a conceptual network enhances learning and transfer for subsequent tasks and whether explicit instruction on task-specific strategies further enhances learning and transfer.…

Reports on the application of Gowin's epistemology to examples from geological inquiry which yield criteria of excellence responsive to the demands characteristic of geological problems. Supporting this approach is a case study about how geologists apply analogies. Contains 33 references. (DDR)

Analyzed are university instructor behaviors in introductory and advanced level laboratories of botany, chemistry, geology, physics and zoology. Science Laboratory Interaction Categories--Teacher (SLIC) was used to assess 15 individual categories of teacher behaviors in the areas of questioning, giving directions, transmitting information,…

Compared preservice elementary teachers (N=58) and geology students (N=51) on their ability to identify rocks and minerals. Anxiety levels were different between the preservice teachers (high) and the geology students (low). Further analysis of geology students indicated a reverse relationship between anxiety and exam performance. (Author/DH)

The study investigated specific student behavior in introductory and advanced college laboratories in botany, chemistry, geology, physics, and zoology. Behaviors were observed, described, and classified with no effort made to induce change, detail underlying conditions, or identify correlates. (Author/RE)

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.…
