The development of cognitive skills to support inquiry learning

Establishing the value of inquiry learning as an educational method, it is argued, rests on thorough, detailed knowledge of the cognitive skills it is intended to promote. Mental models, as representations of the reality being investigated in inquiry learn-ing, stand to influence strategies applied to the task. In the research described here, the hypothesis is investigated that students at the middle school level, and sometimes well beyond, may have an incorrect mental model of multivariable causality (one in which effects of individual features on an outcome are neither consistent nor additive) that impedes the causal analysis involved in most forms of inquiry learning. An extended intervention with 6th to 8th graders was targeted to promote (a) at the metalevel, a cor-rect mental model based on additive effects of individual features (indicated by iden-tification of effects of individual features as the task objective); (b) also at the metalevel, metastrategic understanding of the need to control the influences of other features; and (c) at the performance level, consistent use of the controlled comparison strategy. Both metalevel advancements were observed, in addition to transfer to a new task at the performance level, among many (though not all) students. Findings suppor
