Promoting Statistical Literacy Through Data Modelling in the Early School Years
No full textThis chapter addresses data modelling as a means of promoting statistical literacy in the early grades. Consideration is first given to the importance of increasing young children’s exposure to statistical reasoning experiences and how data modelling can be a rich means of doing so. Selected components of data modelling are then reviewed, followed by a report on some findings from the third-year of a three-year longitudinal study across grades one through three
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
A Narrative Inquiry into Parent Engagement in the Mathematics Curriculum
Get PDFThis thesis is a narrative inquiry into the role of parents in the teaching and learning of mathematics. Over several months, I worked alongside four parent participants to plan a math night for an elementary school. Through our research conversations and our experiences with the math night, I inquired into parents’ role both on and off the school landscape, their views about math curriculum, their relationships with teachers, and the knowledge they have to share about their children in relation to mathematics. As a participant in this research, I share my personal experiences, stories and happenings of my life as a student, teacher, and researcher both before and during this research as well as reflecting on future practices of parent engagement as a teacher. I used the taped conversations from our focus group conversations and my own field notes to apply this research to existing literature. I use Debbie Pushor’s definitions of involvement and engagement to help differentiate between the roles that parents play in the teaching and learning of mathematics. To more specifically define parent engagement, Joseph Schwab’s four curricular commonplaces – learner, teacher, subject matter and milieu are used as a framework to identify with what and with whom parents are engaged. As parents engage in varying degrees and with varying interests, teachers need tools to work with them. Too often, especially when parents are perceived as being “over engaged”, teachers respond negatively to parent engagement in mathematics. I explore ways that teachers can work with parents by listening and acknowledging to them that they have been heard
Implications of Cannabis Legalization on University Student’s Cannabis Use and Associated Outcomes
Get PDFThe recent legalization of recreational cannabis use in Canada suggests that minimal research exists regarding post-legalization trends in cannabis consumption and related outcomes with usage. The purpose of this study was to examine trends in cannabis use, motives to use, and related psychosocial and academic outcomes of usage among students at the University of Saskatchewan. Four hundred and seventy-eight students who had used cannabis in the last six months, ages 18 to 55 years (mean age = 25.02, SD = 5.95) completed a battery of measures designed to examine cannabis use severity and associated constructs (i.e., substance use risk, personal well-being, non-specific psychological distress, academic behaviors, and motivations for use). Among the participants, 31% (n = 148) were found to be hazardous users. Results demonstrated significant small negative associations between cannabis use severity and academic behaviors, personal well-being, and age onset of use, as well as significant positive small associations between cannabis use severity and psychological distress, substance use risk, and all recreational and medicinal motives except for the conformity motive. Hazardous users more often used cannabis for all of the motives, except for the conformity and CNS motives, than non-hazardous users. Lastly, using cannabis for enhancement, coping, expansion, sleep difficulties, and conformity purposes, as well as having impulsive personality traits were found to be important predictors of cannabis use severity, with the enhancement motive identified as the strongest predictor. The small effect sizes found may suggest that legalization has impacted the demographic of cannabis users, with initiatives potentially acting as protective factors against the typical associates of use. Information gleaned from this study can inform prevention and treatment options and the development of campus guidelines for safe cannabis use
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
