How should a wide variety of educational activities be sequenced to maximize student learning? Although some experimental studies have addressed this question, educational data mining methods may be able to evaluate a wider range of possibilities and better handle many simultaneous sequencing constraints. We introduce Sequencing Constraint…

Long term studies of advance organizers (AO) were analyzed with Glass's meta-analysis technique. AO's were defined as bridges from reader's previous knowledge to what is to be learned. The results were compared with predictions from Ausubel's model of assimilative learning. The results of the study indicated that advance organizers were associated…

A study using a biasing paradigm examined four hypotheses regarding specific mechanisms thought to underlie the Assimilation-plus-Correction (A-C) theory of schema-text interactions. According to this theory, the ideas implied by a schema (type-1 ideas) are thought to be assimilated and obscured, while those ideas representing novel information…

A proposal to formulate nomothetic theories -- general statements or scientific laws -- in a way to allow for an immediate test of individual differences is presented. The need for such a proposal is cited in recent developments in structural model building in the area of memory called information processing and in the concern to bring individual…

Science teachers tend to focus on schemas rather than underlying structures with greater explanatory power. One such structure is the recognition that the logical statement implication can only be falsified. After instruction with a modified version of the four-card hypothesis testing task, a grup of 48 preservice elementary teachers were…

The selective learning hypothesis holds that individuals' learning of prose passages will be affected in varying ways by the passages' threatening or unpleasant content. To test this hypothesis, 19 college students read six prose passages--three containing threatening material and three nonthreatening--and then completed a cloze test for each…

Open-ended learning environments (OELEs) like microworlds have been touted as one approach for blending learning theory and emerging technology to support the building of student-centered understanding. The learning process involves developing a theory-in-action--an intuitive theory that is generated and changed by learners as they reflect upon…

This study investigated the possible contribution of pictures serving a representation function to the recall and retention of information presented in written prose passages. The primary variable considered was the durability of picture effects; a second variable concerned the potential effect the presence of pictures had on the recall of…

A study was designed to test the hypothesis that a descriptive-type learning cycle was insufficient to stimulate students to reason at a reflective level or to develop an understanding of, and facility with, the processes of scientific investigation. In order to test the hypothesis, four classes of ninth-grade physical science students (n=100)…
