On the importance of a cognitive processing perspective: an introduction

Children with learning problems require early intervention. If it is evidence based and implemented with integrity and intensity, it will accelerate the academic progress of many students. This is the hope and expectation of the many supporters of responsiveness-to-intervention (RTI). A minority of children, however, will not respond sufficiently to such intervention because of learning disorders like specific learning disabilities (SLD). Some RTI models do not include research-backed methods to identify these children, nor do RTI practitioners often produce the data necessary to develop individualized instruction for them. The authors suggest practitioners go beyond typical RTI assessment data documenting responsiveness/ unresponsiveness to conduct comprehensive evaluations of these most difficult-to-teach students and to include in their evaluations carefully chosen cognitive measures. This special issue presents the work of teams of researchers, which suggests that cognitive and neuropsychological assessments can provide information to further understand SLD, which in turn can guide development of promising interventions.     

Pre-service educators and anti-oppressive pedagogy: interrupting and challenging LGBTQ oppression in schools

There are increasing calls for pre-service educators to be responsive and responsible for anti-homophobic education. This research builds on the ongoing efforts to integrate Positive Space training in our two-year Bachelor of Education programme. We found through a series of focus group and individual interviews that pre-service teachers were aware of Lesbian, Gay, Bisexual, Transgendered, and Queering/Questioning (LGBTQ) oppression, witnessed it in schools, employed a range of strategies, but also experienced challenges due to power dynamics in schools, and may not have recognised the power of their interruptions. Our findings suggest that Positive Space training is valuable and necessary and needs to continue to be explicitly embedded in core courses so that all pre-service teachers, regardless of their discipline, develop the skills and attitudes necessary to be advocates for LGBTQ individuals.     

Is it time well spent? The relationship between time management behaviours,perceived effectiveness and work‐related morale and distress in a university context

Despite the high ‘guru‐factor’ in time management, few claims have been subjected to empirical investigation. This study tests the claims that people who manage their time well perceive themselves to be more effective and feel less stressed. University staff and students were utilized to investigate the relationship between time management related behaviours, perceived effectiveness, and work‐related morale and distress. Results suggested a hierarchy of time management behaviours. Having a clear sense of career purpose was most important for perceived effectiveness at work, followed by planning and prioritizing. This study has significant practical implications for staff and students. If the aim of using time management strategies is to improve performance and reduce stress, people need to learn to identify the purpose in their career, then plan their time accordingly, rather than tidying desks and hanging ‘do not disturb’ signs on doors.     

The association between academic self‐beliefs and reading achievement among children at risk of reading failure

This paper investigates whether children's academic self‐beliefs are associated with reading achievement and whether the relationship is modified by gender and/or age. Data were collected from children at risk of reading failure, that is, emergent readers (6‐ to 8‐year‐olds) in socioeconomically disadvantaged areas reading at a level below the population mean. The authors' own measure of attitude to reading and perceived competence was used. The study found a significant positive association between attitude to reading in class and vocabulary and phonemic awareness and a significant negative association between perceived competence at reading in class and single‐word reading and spelling. Girls' attitude to reading and perceived competence were more positively associated with reading achievement, and this was most evident in the first grade. Perceived competence was inflated among those with the poorest reading and also among boys, in association with reading‐related skills found most challenging by children in this sample.

A Deliberate Practice Approach to Teaching Phylogenetic Analysis

One goal of postsecondary education is to assist students in developing expert-level understanding. Previous attempts to encourage expert-level understanding of phylogenetic analysis in college science classrooms have largely focused on isolated, or “one-shot,” in-class activities. Using a deliberate practice instructional approach, we designed a set of five assignments for a 300-level plant systematics course that incrementally introduces the concepts and skills used in phylogenetic analysis. In our assignments, students learned the process of constructing phylogenetic trees through a series of increasingly difficult tasks; thus, skill development served as a framework for building content knowledge. We present results from 5 yr of final exam scores, pre- and postconcept assessments, and student surveys to assess the impact of our new pedagogical materials on student performance related to constructing and interpreting phylogenetic trees. Students improved in their ability to interpret relationships within trees and improved in several aspects related to between-tree comparisons and tree construction skills. Student feedback indicated that most students believed our approach prepared them to engage in tree construction and gave them confidence in their abilities. Overall, our data confirm that instructional approaches implementing deliberate practice address student misconceptions, improve student experiences, and foster deeper understanding of difficult scientific concepts.     

An iPod (MP3) Library Tour for First-Year Students

This article describes the creation and evolution of an iPod (MP3) Library Tour and Assignment at the University of South Carolina (USC) Upstate. Designed as an integral part of the First-Year Information Literacy Program, the tour functions as an orientation to the layout of the physical library, including its collections and major service points. Issues addressed are the collaboration that led to the adoption of the tour, the results of a student survey that led to significant revisions, and the unique place of the tour's being required for a first-year program.
