This article combines different conceptualizations of teachers' diagnostic competence in listening to students' mathematical thinking processes on the levels of general perspectives, noticed aspects and activated didactic categories. An empirical study of 159 prospective mathematics teachers' diagnostic judgments investigated how these levels are…

This study investigated the effectiveness of Brainfeed intervention programme as an alternative approach for supporting people living with dyslexia. The study adopted a quasi-experimental research design. The population of this study is made up of twenty four thousand seven hundred and twenty seven (24,727) senior secondary school students (S.S.2)…

We examined the use of balance and inverse methods in equation solving. The main difference between the balance and inverse methods lies in the operational line (e.g. +2 on both sides vs -2 becomes +2). Differential element interactivity favours the inverse method because the interaction between elements occurs on both sides of the equation for…

Previous studies revealed inconsistent findings about the effects of cognitively low or high demanding interpolated tasks during incubation period on post-incubation creative performance. To explain this contradiction, two intervention tasks were administered (Reflecting on the generated ideas [RF] and the Word puzzle task [WP]), which are…

With applications of Tree of Life data becoming ever more prevalent in everyday contexts, tree thinking has emerged as a vital component of scientific literacy. This article reports a study testing the hypothesis that instruction in natural selection, which is the primary focus of US evolution education at the high school and introductory college…

This study looked at the interplay of the analyst verbal speech acts and the process of change in a psychoanalytic treatment. Using a single case design on the session transcripts of the well studied case of Mrs. C., following Halfon and Weinstein's (2013) methodology the study tracked linguistic patterns as represented by the interaction of…

No previous empirical study has investigated whether the learning disabilities (LD) identification decisions of proposed methods to operationalize processing strengths and weaknesses approaches for LD identification are associated with differential treatment response. We investigated whether the identification decisions of the…

Learning algebra is difficult for many students in part because of an emphasis on the memorization of abstract rules. Algebraic reasoners across expertise levels often rely on perceptual-motor strategies to make these rules meaningful and memorable. However, in many cases, rules are provided as patterns to be memorized verbally, with little overt…

Using multitrait, multimethod data, and confirmatory factor analysis, the current study examined the effects of arithmetic item formatting and the possibility that across formats, abilities other than arithmetic may contribute to children's answers. Measurement hypotheses were guided by several leading theories of arithmetic cognition. With a…

Purpose: The purpose of this paper is to assess the effects of scenario planning on participant mental model styles. Design/methodology/approach: The scenario planning literature is consistent with claims that scenario planning can change individual mental models. These claims are supported by anecdotal evidence and stories from the practical…

The purposes of this study were to investigate the effects of an intervention designed to improve at-risk 4th graders' understanding of fractions and to examine the processes by which effects occurred. The intervention focused more on the measurement interpretation of fractions; the control condition focused more on the part-whole interpretation…

This article demonstrates how the broad and narrow abilities and processes that comprise Cattell-Horn-Carroll (CHC) theory and their relations to specific academic outcomes have begun to transform our current understanding of the definition of and methods for identifying specific learning disability (SLD), particularly in the school setting. The…

Response to intervention (RTI) must be combined with comprehensive cognitive assessment to identify children with learning disabilities. This article presents the Cognitive Hypothesis Testing (CHT) model for integrating RTI and comprehensive evaluation practices in the identification of children with reading disabilities. The CHT model utilizes a…

This research tested the hypothesis that students' erroneous mental models about groundwater will change towards more valid concepts if they are taught on the basis of a mental model-building strategy that focuses on the clarification of students' misconceptions. To examine the hypothesis a quasi-experimental research design was chosen. The…

This document presents some of the major challenges facing Developmental Psychologists. Research revealed that middle class children tended to respond in classification tasks to objects and pictures as equivalents, whereas low class black children tended not to do so. The reason for this was investigated. This investigation of the course of…
