Working memory capacity and disfluency effect: an aptitude-treatment-interaction study

According to Cognitive Load Theory, learning material should be designed in a way to decrease unnecessary demands on working memory (WM). However, recent research has shown that additional demands on WM caused by less legible texts lead to better learning outcomes. This so-called disfluency effect can be assumed as a metacognitive regulation process during which learners assign their cognitive resources depending on the perceived difficulty of a cognitive task. Increasing the perceived difficulty associated with a cognitive task stimulates deeper processing and a more analytic and elaborative reasoning. Yet there are studies which could not replicate the disfluency effect indicating that disfluency might be beneficial only for learners with particular learner characteristics. Additional demands on working memory caused by disfluent texts are possibly just usable by learners with a high working memory capacity. Therefore the present study investigated the aptitude-treatment-interaction between working memory capacity and disfluency. Learning outcomes were measured by means of a retention, a comprehension, and a transfer test. Moreover, the three types of cognitive load (intrinsic, extraneous, and germane) were assessed. The results revealed significant aptitude-treatment-interaction effects with respect to retention and comprehension. Working memory capacity had a significant influence only in the disfluency condition: The higher the working memory capacity, the better the retention and comprehension performance in the disfluency condition. No effects were found with respect to transfer or cognitive load. Thus, the role of metacognitive regulation and its possible effects on cognitive load need further investigation.     

A Step-by-Step Design and Development of an Integrated Educational Software to Deal with Students' Empirical Ideas about Mechanical Interaction

We present the educational software Interactions between Objects, which we designed and developed to assist constructive teaching of Newton's 3rd law and Newtonian Dynamics in general. The software was designed on the basis of students' empirical ideas and conceptual difficulties, identified from previous research with Greek students (11–16 years old), the main findings of which are presented. We describe the step-by step design of this software, which aims to help students reconstruct their knowledge in the action–reaction thematic field through a number of experiments, by simulating real everyday life situations of interaction between bodies, modeling those situations by the help of an appropriate didactic method, applying cognitive conflict processes and supporting run my model features to promote students' conceptual change in this physics area.     

Learning through Leading: A Self-Study in District Administration

There is little research in the area of understanding educational leaders’ psychological processes. This lack of understanding leaves educational leaders to develop their own sense-making practices while in the complex and stressful act of leading. This self-study, conducted over more than half a school year in 2014–2015, was my own effort to do just that: to understand myself as a leader by examining various influences on my role using a four-quadrant framework for leadership. The findings highlight two significant areas influencing my leadership practices: the internal-entity quadrant, defined as the leader’s personal values and beliefs, and the internal-context quadrant, defined as the leader’s perception of the various contextual influences surrounding her role. Adopting this framework for my thinking allowed a more objective view of my practice and the beliefs and assumptions operating within my practice. While this work is, at a personal level, my own struggle to understand the complexities of leading, it is also examines one way in which district leaders might begin to think about their own sense-making practices using self-study methods.     

Critical Literacy,Disciplinary Literacy: Reading the Engineering-Designed World

Globally, many people spend most of their time interacting with the products of engineering design as they wear clothes, drink clean water, use transportation systems, and more. Given the omnipresence of engineering design, whose material results are felt daily in people’s lives, it seems especially important that students learn to recognize and question how certain designs promote the welfare and interests of some while remaining inaccessible to others. In this article, we outline a vision for critical literacy instruction in engineering that simultaneously incorporates and challenges professional standards. We—an associate professor of literacy, an engineer, and a teacher at an engineering-focused high school—illustrate how critical literacy instruction might be enacted in the context of engineering design instruction in high schools. We describe how critical literacy can complement disciplinary literacy instruction in engineering as students use critically-focused, disciplinary lenses to move toward social justice.     

Adolescents’ conceptions of learning and education about sex and relationships

Abstract

In order for adolescents to learn about sex and relationships, the education must be of significance and meet their needs and interests. The study investigated adolescents’ conceptions of learning and education about sex and relationships. A phenomenographic approach was used. Six focus group interviews were conducted with adolescents ages 18–19 in Sweden. The results showed that stable ground for learning implies select issues of importance, that is, values and prejudices, up-to-date knowledge, and practical skills. These issues should be dispersed throughout the school years in relation to the students’ own maturity. This seemed to enable internalization of different aspects of sex and relationships. Learning about sex and relationships can create meaning for youth and generate progress by fostering autonomy and identity, correcting misconceptions, counteract prejudices, not in isolation rather in society in a defined culture.     

Back to Africa: Tracing Dyslexia Genes in East Africa

A sample of Swahili-speaking probands with reading difficulties was identified from a large representative sample of 1,500 school children in the rural areas of Tanzania. Families of these probands (n = 88) were invited to participate in the study. The proband and his/her siblings received a battery of reading-related tasks and performance on these tasks was recorded and treated as phenotypic data. Molecular-genetic analyses were carried out with 47 highly polymorphic markers spanning three previously identified regions of interest harboring susceptibility loci for reading difficulties: 2p, 6p, and 15q (DYX1–DYX3). The analyses revealed the involvement of these regions in the development of reading difficulties in Swahili. The linkage signals are especially pronounced for time (compared with error) indicators of reading difficulties. These findings are easily interpretable because in transparent languages such as Swahili deficits in reading are more related to the rate/speed of reading and reading-related processes than to the number of errors made. In short, the study incrementally advances the field by adding an understudied language and an understudied population to the variety of languages and populations in the field of molecular-genetic studies of reading difficulties.     

Prospective relations among victimization, rejection, friendlessness, and children's self- and peer-perceptions

This study investigated the prospective links between three forms of peer adversities (i.e., victimization, rejection, and lack of reciprocated friendships) and children's perceptions of themselves and of their peers. The sample consisted of 212 children (107 boys and 105 girls, 11-13 years) recruited from four primary schools and followed up for a period of one year. The results showed that a negative self-perception was a risk factor for the development of all forms of peer adversities. Of the three forms of peer adversities assessed, victimization and rejection had an influence on children's peer perceptions. None of the peer adversities predicted changes in self-perceptions. The results partially support a transactional model between children and their environments.     

Evaluation systems and the pace of change – The example of Swedish higher education1

Abstract

The aim of¹ this article is to illuminate and discuss evaluation and evaluation systems in relation to the pace of change. It is argued that evaluation promotes and accelerates change. The article will thus contribute to a critical scrutiny of evaluation as a societal phenomenon and as a widespread practice in education. To accomplish this aim, the inherent purpose of evaluation and evaluation systems is brought forward. National evaluation systems for Swedish higher education are used as an empirical example. An analysis using Rosa’s three aspects of social acceleration (technical acceleration, acceleration of social change, and acceleration of the pace of life) is offered to demonstrate how the evaluation systems are related to, sustain, and promote an increase of the pace of change (acceleration) in educational practice in higher education.     

Mothers of children with externalizing behavior problems: cognitive risk factors for abuse potential and discipline style and practices

OBJECTIVE: Utilizing the conceptual framework of the Social Information Processing (SIP) model (Milner, 1993, 2000), associations between cognitive risk factors and child physical abuse risk and maladaptive discipline style and practices were examined in an at-risk population. METHODS: Seventy-three mothers of 5-12-year-old children, who were identified by their therapist as having an externalizing behavior problem, responded to self-report measures pertaining to cognitive risk factors (empathic perspective taking, frustration tolerance, developmental expectations, parenting locus of control), abuse risk, and discipline style and practices. The Child Behavior Checklist (CBCL) provided a confirmation of the child's externalizing behaviors independent of the therapist's assessment. RESULTS: The results of this study suggest several cognitive risk factors significantly predict risk of parental aggression toward children. A parent's ability to empathize and take the perspective of their child, parental locus of control, and parental level of frustration tolerance were significant predictors of abuse potential (accounting for 63% of the variance) and inappropriate discipline practices (accounting for 55% of the variance). CONCLUSIONS: Findings of the present study provide support for processes theorized in the SIP model. Specifically, results underscore the potential role of parents' frustration tolerance, developmental expectations, locus of control, and empathy as predictive of abuse potential and disciplinary style in an at-risk sample.
