Examines the effects of writing assignments on more than 250 undergraduate students' attitudes and on their classroom performance. The experimental writing group perceived both the subject matter and the course requirements more favorably, and also scored somewhat higher on average for the final examination, though not significantly higher than…

Presents a prototypical case illustrating what positivist research means and argues that even critics of positivist research are logically committed to propositions that can be tested only through positivist research paradigms. The relationship between the nature of a community's research enterprise and its educational provisions must be causal.…

Effects of schema-based cues (previewing) and structure-based cues (structure cueing) on comprehension of expository prose were studied with 74 fourth graders. Results indicate a significant pattern of higher performance by the previewing group, in comparison with the structure-cued group and a control group. (SLD)

Reexamines definitions of and explanations for the Hawthorne Effect in research subjects. Notes that the Hawthorne Effect was tested in a study of the effectiveness of paired classroom reading among students. Challenges the notion that subject's behavior is modified by participation in research. Reviews various research studies that question the…

Evidence is presented that strengthens the argument against comparison group research strategies. Results from a study of youth attitudes related to the California Conservation Corps involving 528 participants and 668 comparisons indicate that the comparison group may not adequately represent the nontreatment state.

Follow-up evaluation data were collected after one year on a program to teach young children about phonemic structures. Results with 63 experimental subjects in first grade and 56 controls indicate that children who enter school with advanced phonemic awareness score high on measures of word identification, decoding, and spelling. (SLD)

Involving students in inquiry-based exercises is much more difficult than simply providing activities for them to do in the classroom. While active learning suggests students are physically participating in the lesson, inquiry learning requires that they are also mentally participating in it. Academic theorists agree it is more the mental…

Past research has indicated that a number of problems in the teaching of science in elementary classrooms are rooted in the preparation of inservice teachers. One continuing concern is elementary teachers' lack of science content knowledge. As indicated by numerous research studies reporting positive results, one method of addressing these…
