Self-instructional booklets containing the advance organizer, cognitive set, and post organizer varying according to experimental treatment were randomly assigned within nine Algebra 2 classes. Results showed a significant interaction between advance and post organizers: either one used separately facilitated learning and retention, but when used…

Programed units of instruction designed with four different sequences of characterizations and exemplifications of disjunctive concepts were given to preservice elementary school teachers. Students were tested on three levels of concept attainment, with differences between strategies resulting, as one moves through the levels of cognitive…

Grade nine students (n=116) were assigned to five different algebra word problem test versions: textbook, student, pictorial, textbook plus pictorial, and student plus pictorial versions. Analysis by IQ levels yielded results different from those obtained in previous studies. (JP)

This critique points out some possible limitations of a previously reported study on the relative efficacy of two feedback modes during CAI instruction. Researchers are cautioned about using results to suggest classroom instructional practices. See also SE 508 622. (LS)

The author answers the questions posed in a critique of his previously published study on the relative efficacy of two feedback modes during CAI instruction. Details which were originally omitted due to lack of space are provided for further clarification. See also SE 508 621. (LS)

Self-instructional booklets varying advance organizers, post organizers, and knowledge of behavioral objectives according to experimental treatment were used with 348 eighth graders and 259 preservice elementary education students. A significant interaction between the advance and the post organizers was found on one learning test. Students scored…

This critique discusses Gagne's position that students should understand how to mathematize a concrete situation and validate a solution but need not understand how a solution is derived. Reconciling his views with those of mathematics educators and raising questions are both included. (MNS)

Gagne's reply to critiques by Wachsmuth and by Steffe and Blake notes that their approaches are from different points of view. He urges that mathematics educators examine critically the view that understanding involves some aspects of the structure of mathematics. (MNS)

Research was viewed as needed to establish a classification scheme for the major areas of difficulties individual students have in solving word problems. The results suggest that inability to read problems is a major obstacle for sixth graders, and mastery of components of problem solving ensures process mastery. (MP)
