Most timeline analogies of geologic and evolutionary time are fundamentally flawed. They trade off the problem of grasping very long times for the problem of grasping very short distances. The result is an understanding of relative time with little comprehension of absolute time. Earlier work has shown that the distances most easily understood by…

Presents lecture outline comparing uniformitarianism with other philosophic approaches to earth study. Comparison is valuable since: (1) it provides insight into the character of geology and the meaning of the scientific method; and (2) it reveals the necessarily biased nature of all information. (Author/JN)

Describes a study on the performance of Internet notes and PowerPoint lecture slides in a physical geology course and compares it with the traditional lecturing method. (Contains 12 references.) (YDS)

The study reported here concludes that the laboratory does help students in their geology lecture course work even though the content emphases are different. (MDR)

Self-paced and lecture versions of a general geology course were taught by the same instructor using identical exams and nearly identical instructional materials. No significant differences were found in apparent scholastic abilities, exam results, or levels of satisfaction with the course. Enrollment was notably higher in the lecture version.…

Twenty lectures by native speaker geology lecturers to nonnative speaker students were transcribed, and 921 instances of vocabulary elaboration were coded into a computer database according to 20 linguistic features. Analysis revealed noticeable variation among lecturers in language range/technicality, vocabulary elaboration, signalling, and use…

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…

Compared are two approaches to inservice geology instruction for elementary and secondary school earth science teachers. The benefits of the combination of lecture, laboratory, and field work are emphasized. (CW)

A study at Sultan Qaboos University in Oman investigated the listening comprehension problems of students who were non-native speakers of English (NNS), in lectures by native English-speaking professors. Two professors with no previous experience in teaching non-native speakers introduced geology in 4 weeks of lectures. Instances of vocabulary…
