Model-based reasoning in a year 10 classroom

Studies have shown that secondary school students experience difficulties making scientific models meaningful, yet explanatory models are central to the development of scientific understanding. This study investigated the extent and nature of students' model-based reasoning in a laboratory investigation. It was an interpretive study involving a single Year 10 Science class investigating the influence of six factors on electrical resistance. Before commencing their practical investigations students were re-familiarised with the “electron drift” model of metals. Data sources included videotapes of classroom interactions, audiotaped interviews with students, student workbooks showing their experimental procedures and results, and explanations of those results. The research suggests that spontaneous use of the model in explanations increased over the duration of the task but that the explanations were restricted mainly to model-based reasoning with lower order relational mapping. Even after further formal instruction on the model after the initial experimental investigations, many students were still unable to use the model effectively, displaying mainly the same level of reasoning. As model-based reasoning is an important part of learning some aspects of science, it is imperative that science educators take appropriate steps to facilitate the development of such reasoning in appropriate contexts.     

Children’s Visual Scanning of Textual Documents: Effects of Document Organization,Search Goals,and Metatextual Knowledge

This study examines children’s strategies when scanning a document to answer a specific question. More specifically, we wanted to know whether they make use of organizers (i.e., headings) when searching and whether strategic search is related to their knowledge of reading strategies. Twenty-six French fifth graders were asked to search single-page documents presented on the screen of an eye tracker in order to respond to questions requiring the location of information in either a single paragraph (Location questions) or multiple paragraphs (Comparison questions). Location questions were easier and faster to answer than Comparison questions. The presence of headers led to more selective reading strategies but did not significantly speed up the search. Strong individual differences were observed in children’s scanning strategies: Some systematically fixated headers, whereas others did not. These differences were not significantly related to the participants’ decoding or comprehension skills but rather to their knowledge of reading strategies.     

Childhood trauma and suicide risk in a sample of young individuals aged 14–35 years in southern Brazil

Suicide is among the main causes of death of people aged between 15 and 44 years old. Childhood trauma is an important risk factor for suicide. Hence, the objective of this study was to verify the relationship between childhood trauma and current suicide risk (suicidal behavior and ideation) in individuals aged 14–35 years, in the city of Pelotas, Brazil. This is a cross-sectional, population-based study. Sample selection was performed by clusters. Suicide risk was evaluated using the Mini International Neuropsychiatric Interview (MINI) and Childhood trauma was assessed with the Childhood Trauma Questionnaire (CTQ). Moreover, the participants responded to a questionnaire concerning socioeconomic status, work, and substance use. The sample was composed of 1,380 individuals. The prevalence of suicide risk was 11.5%. The prevalence figures of childhood trauma were 15.2% (emotional neglect), 13.5% (physical neglect), 7.6% (sexual abuse), 10.1% (physical abuse), and 13.8% (emotional abuse). Suicide risk was associated (p < .001) with gender, work, alcohol abuse, tobacco use, and all types of childhood trauma. The odds of suicide risk were higher in women (OR = 1.8), people who were not currently working (OR = 2.3), individuals who presented alcohol abuse (OR = 2.6), and among tobacco smokers (OR = 3.4). Moreover, suicide risk was increased in all types of trauma: emotional neglect (OR = 3.7), physical neglect (OR = 2.8), sexual abuse (OR = 3.4), physical abuse (OR = 3.1), and emotional abuse (OR = 6.6). Thus, preventing early trauma may reduce suicide risk in young individuals.     

Student satisfaction in higher education: a meta-analytic study

This paper discusses the results of a meta-analysis performed to identify key antecedent and consequent constructs of satisfaction in higher education. We offer an integrated model to achieve a better understanding of satisfaction in the context of higher education. To accomplish this objective, we identified 83 studies that were valid and relevant to the research objective of the current study, generating a total of 469 observations. We identified studies published from 1986 to 2016 and analyzed six antecedent dimensions (perceived value of educational services, resources provided to the student, service quality perception, marketing orientation, identity of the higher education institution, university environment) and one consequent dimension related to satisfaction. The 7 dimensions exhibited a total of 51 relationships. We believe that the originality of the findings clearly contributes to future academic research in higher education.     

Intercultural Communication Competence Scale: Invariance and Construct Validation in Portugal

ABSTRACT

This article explores the psychometric validation of an Intercultural Communication Competence (ICC) scale. Three studies were performed: (1) psychometric evidence pertaining to the scale’s reliability and factor structure and an analysis of the measurement invariance; (2) assessment of convergent and predictive validity; and (3) analyzes the association between ICC and affective and cognitive dimensions of cultural empathy. A three-factor model with eight items yielded the best fit to the data. The scale showed non-invariance between genders, but proved to be a predictor of intercultural contact. Convergent validity were demonstrated.     

Collaborative learning processes in the context of a public health professional development program: a case study

The health promotion laboratory (HPL – Canada) is a public health professional development program building on a collaborative learning approach in order to support long-term practice change in local health services teams. This study aims to analyse the collaborative learning processes of two teams involved in the program during the first year of implementation. Based on a multiple case study design involving observations, interviews, and documentary sources, the study: (1) describes the learning process by which each team built a common understanding of the problem at hand and developed an intervention to address it; (2) identifies factors that facilitated or hindered these processes; and (3) proposes a cross-case explanation of the collaborative learning process in the HPL. The results demonstrate that the two teams learned by expanding their repertoire of actions, albeit experiencing different processes. Results point to the central role of shared mental models and key influencing factors, such as commitment and participation (team cohesion), team climate (psychological safety), and leadership style. Unlike previous studies on team learning that concentrated on existing teams in organisations, the current research studied purposely created teams working at transforming their practices and showed that they can successfully learn if specific conditions are achieved.     

Achieving scientific excellence: An exploratory study of the role of emotional and motivational factors

This study investigates the perceived role of psychological factors in achieving excellence in scientific research. Six outstanding scientists aged 33–42 were interviewed. Data were analyzed inductively resulting in three main dimensions: personality traits and characteristics, psychological skills and processes, and task-specific strategies. Researchers highlighted the importance of emotional factors and motivational processes to achieve and sustain scientific excellence. Flexible coping, emotion regulation, and goal setting were emphasized and described as particularly important in dealing with rejections, setbacks, and team management issues. Persistence and adaptive perfectionism were key individual characteristics which helped participants in nurturing and sustaining motivation. This study suggests that the specific impact of emotional, motivational, and other psychological skills at different stages of excellence development is relevant; yet, further investigation is needed.     

Responding to university policies and initiatives: the role of reflexivity in the mid-career academic

How do academics make sense of university policies and strategic initiatives and act on them? Interviews were conducted with 27 mid-career academics in different disciplines, different research-intensive university environments and two countries (England and Australia). Data were analysed iteratively utilising a critical realist perspective, specifically, Archer’s modes of reflexivity. The paper argues that individuals’ responses to university policies and initiatives, to changes in policy and policy conflicts, can at least partially be understood through interrogating the modes of reflexivity they employ.     

Determinants of increasing duration of first unemployment among first degree holders in Rwanda: a logistic regression analysis

Unexpectedly, the duration of first unemployment among first degree holders has quickly increased in Rwanda after considerable loss of the skilled labour during the war and Genocide perpetrated against Tutsi in 1994. The time it takes a higher education graduate to land a first employment is a key indicator for the evaluation of and optimal investment in higher education. A long-term first unemployment has negative psychosocial and economic consequences, and is an interplay of diversified factors. Yet, these factors have not been ascertained in Rwanda, whereas their knowledge is crucial for an efficient planning of higher education and employability of the graduates. This study aimed to fill in this knowledge gap for the period 1998–2009. We fitted a binary logistic regression model to data from the 2010 Employer and Graduate Survey (n = 1007) that was conducted by the National University of Rwanda. The results showed that the duration of first unemployment was significantly associated to the graduate’s age, job search method, acquired skills, further graduate studies, monthly salary and category of employing institution. The results suggest that the higher education sector should identify and fill skills gaps in the existing curricula or its delivery with reference to the labour market requirements.
