The present study was an attempt to investigate the effects of two factors - number of defining attributes and the degree to which a student has learned those attributes (level of conceptualization) - on the difficulty of a concept. (Author)

College students read two passages. Four groups answered questions requiring either a summary, a new example of the concept, a list of critical attributes of the concept, or identification of a new example. The "identify post-question group" showed the greatest accuracy in classifying new examples. (Author/MH)

Relatively simple changes in cognitive activities during prose learning can substantially affect information acquisition, yet many students' strategies are ineffective. A prose learning strategy training program using network models of long-term memory structure and depth-of-processing theory is presented with evidence of its effectiveness among…

Effects of author-generated and learner-generated elaborations on subjects' abilities to recall, classify, and apply conceptual knowledge were compared for 94 college undergraduates studying a passage on psychological concepts. Author-generated elaborations and specific elaboration activities produced superior effects in comparison with…

High school students of various ability levels were presented economics concepts lessons, varied according to their organization or structure. Test questions over concept ranged from simple recall of information to application of economics principles. Students scored generally higher when they were presented highly structured lessons.

The number of video examples of a concept and the dispersion of the examples were studied as variables affecting concept learning by 50 Dutch 12-year-old and 14-year-old secondary students. Although the number had no effect, broadly dispersed examples improved posttest classification ability. Implications for concept teaching are discussed. (SLD)
