EFFECT OF THE PRESENCE OF EXTERNAL REPRESENTATIONS ON ACCURACY AND REACTION TIME IN SOLVING MATHEMATICAL DOUBLE-CHOICE PROBLEMS BY STUDENTS OF DIFFERENT LEVELS OF INSTRUCTION

This study explores the effects of the presence of external representations of a mathematical object (ERs) on problem solving performance associated with short double-choice problems. The problems were borrowed from secondary school algebra and geometry, and the ERs were either formulas, graphs of functions, or drawings of geometric figures. Performance was evaluated according to the reaction time (RT) required for solving the problem and the accuracy of the answer. Thirty high school students studying at high and regular levels of instruction in mathematics (HL and RL) were asked to solve half of the problems with ERs and half of the problems without ERs. Each task was solved by half of the students with ERs and by half of the students without ERs. We found main effects of the representation mode with particular effect on the RT and the main effects of the level of mathematical instruction and mathematical subject with particular influence on the accuracy of students’ responses. We explain our findings using the cognitive load theory and hypothesize that these findings are associated with the different cognitive processes related to geometry and algebra.     

‘Tough love and tears’: learning doctoral writing in the sciences

Contemporary changes to the doctorate mean student researchers are likely to be expected to write differently, write more and more often, and yet, despite a growing interest in doctoral education, we still know relatively little about the teaching and learning practices of students and supervisors vis-a-vis doctoral writing. This paper draws from a research study into the writing experiences of higher degree students and their supervisors in one science, health and technology-based university Faculty. The study used surveys, interviews and focus groups to collect information from students and supervisors about their experiences of doctoral writing and their perceptions about its development. By attending to the writing-related pedagogical practices of supervisors, this article explores how doctoral writing can be the stage for the playing out of tensions over changing roles and identities aggravated by contemporary pressures on doctoral education.     

Supplementing literacy instruction with a media-rich intervention: Results of a randomized controlled trial

This study investigates whether a curriculum supplement organized as a sequence of teacher-led literacy activities using digital content from public educational television programs can improve early literacy outcomes of low-income preschoolers. The study sample was 436 children in 80 preschool classrooms in California and New York. Preschool teachers were randomly assigned to implement either a 10-week media-rich early literacy intervention that employed clips from Sesame Street, Between the Lions, and SuperWhy! or to a comparison condition. The media-rich literacy supplement had positive impacts (+0.20 ≤ d ≤ +0.55) on children's ability to recognize letters, sounds of letters and initial sounds of words, and children's concepts of story and print. The study findings show the potential for incorporating literacy content from public media programming into curriculum supplements supported by professional development to impact early literacy outcomes of low-income children.     

PISA Data: Raising concerns with its use in policy settings

This article considers the role played by policy makers, government organisations, and research institutes (sometimes labelled “think tanks”) in the analysis, use and reporting of PISA data for the purposes of policy advice and advocacy. It draws on the ideas of Rizvi and Lingard (Globalizing Education Policy, 2010), Bogdandy and Goldmann (Governance by Indicators/ Global Power through Quantification and Rankings, 2012) and others to explore the ways in which such “agents of change” can interpret, manipulate and disseminate the results of data arising from large scale assessment survey programs such as PISA to influence and determine political and/or educational research agendas. This article illustrates this issue by highlighting the uncertainty surrounding the PISA data that have been used by a number of prominent, high profile agents of change to defend policy directions and advice. The final section of this paper highlights the need for policy makers and their advisors to become better informed of the technical limitations of using international achievement data if such data are to be used to inform policy development and educational reforms.     

Designing for expansive science learning and identification across settings

In this study, we present a case for designing expansive science learning environments in relation to neoliberal instantiations of standards-based implementation projects in education. Using ethnographic and design-based research methods, we examine how the design of coordinated learning across settings can engage youth from non-dominant communities in scientific and engineering practices, resulting in learning experiences that are more relevant to youth and their communities. Analyses highlight: (a) transformative moments of identification for one fifth-grade student across school and non-school settings; (b) the disruption of societal, racial stereotypes on the capabilities of and expectations for marginalized youth; and (c) how youth recognized themselves as members of their community and agents of social change by engaging in personally consequential science investigations and learning.     

A blended learning curriculum for training peer researchers to conduct community-based participatory research

Peer researchers (PRs) are research team members who share traits (e.g. gender, age, sexual orientation, diagnosis, income, housing situation, etc.) with study participants. Participatory methods and some fields (e.g. HIV/AIDS) expect PRs to be equitably involved in a project. Moreover, in Canada, there is a current impetus to include ‘the patient’ in health research. PRs often join a project without any formal research training, yet they are frequently tasked with suggesting appropriate language, recruiting participants, conducting interviews, administering surveys, analyzing data, and presenting findings. While there is literature on PR hiring, ethical considerations of PR engagement, and PR experiences, the methods of training PRs remain underreported. A blended learning curriculum (i.e. combination of webinars, didactic in-person presentation, filmed simulation, etc.), informed by the principles of action learning and the concept of reciprocity, has shown preliminary effectiveness in training PRs across two studies. This paper will present the curriculum, alongside exploratory evaluation results (n?=?7), with details on how the curriculum changed from one study to the next and how reciprocity between academic and peer researchers led to stronger collaborations.     

Addressing Sexual Assault on College Campuses: Guidelines for a Prevention/Awareness Week

The authors discuss concepts that are related to providing education and training regarding sexual assault, as outlined by the Crime Awareness and Campus Security Act of 1990, as amended in 1992. Because college counseling center staff members often initiate and plan campus outreach prevention programs, an outline is provided of a prevention/awareness week intervention that is designed to address sexual assault on university and college campuses.     

Discrepant stakeholder perspectives on graduate employability strategies

A literature review identified 12 strategies that have been empirically linked to improvements in graduate employability. A survey methodology was used to investigate self-reported use and/or perspectives on these strategies among four stakeholder groups. The following questions were asked: to students – What strategies are you using to improve your graduate employability; to graduates – What strategies did you use to improve your employability?; to higher education career development professionals and educators – Which of the following employability strategies do you provide for students?; and to employers – Which of the following strategies undertaken by students does your organisation value when recruiting graduates? Across the four stakeholder groups, 705 responses were received and analysed. The key findings were discrepancies between the strategies reported in the literature and those indicated in the surveys, as well as discrepancies between stakeholder groups in regard to which strategies were indicated.     

A group randomized controlled trial evaluating parent involvement in whole-school actions to reduce bullying

Parents can significantly affect children's peer relationships, including their involvement in bullying. The authors developed and evaluated ways to enhance parents’ knowledge, self-efficacy, attitudes, and skills related to parent–child communication about bullying. The 3-year Friendly Schools Friendly Families whole-school intervention included a family component, which provided training and resources to support school teams to engage families in awareness-raising and skill-building activities. Over 3,200 parents of the Grade 2, 4, and 6 cohorts were recruited. For the Grade 2 and 4 cohorts at both 10 and 22 months postintervention, the family component increased parents’ self-efficacy to talk about bullying with their children and their frequency of doing so. Grade 4 parents reported more provictim attitudes at 22 months. No differences were found for the Grade 6 cohort. These data suggest a whole-school capacity-building intervention in early and middle childhood can improve the likelihood and frequency of positive parent–child communication about bullying.
