Understanding Student Attempts to Find a Line of Fit

The least squares method of fitting a line is not one that naturally occurs to students. We present three tasks to understand student views on how lines may be fit.     

Investigating teachers’ professional learning in an advanced Master’s degree programme

This study examined how multiple measures can be used to study experienced teachers’ learning. The study was conducted in an advanced Master’s degree programme, aligned with the National Board for Professional Teaching Standards in the United States. The programmatic features and key learning experiences found in the programme are described and connected to the multiple measures used to investigate teachers’ professional learning. Results of the study indicated that multiple measures can be used to examine a programme’s effects on teacher learning; prompted reflections can provide evidence of a programme’s influence on teacher thinking; and programme structure and content are important elements to consider when designing and assessing programmes for experienced teachers. This study also addresses how building a programme around measurable outcomes and then examining the results through multiple measures is an important link in understanding teacher learning.     

Evidence of alphabetic knowledge in writing: connections to letter and word identification skills in preschool and kindergarten

The writing skills of 286 children (157 female and 129 male) were studied by comparing name writing and letter writing scores from preschool to kindergarten with letter and word reading scores over the same time period. Two rubrics for scoring writing were compared to determine if scores based on multiple components (i.e., letter formation, orientation on the vertical axis, left–right orientation, and correct letter sequencing) would better reflect differences in children’s writing knowledge in preschool and kindergarten than rubrics composed of one component (i.e., letter formation only). While developmental changes in writing scores were found, little additional information was provided by multiple component scoring rubrics compared to the single component rubric. Letter writing scores were more strongly related to letter and word reading scores than name writing scores but neither writing score was predictive of growth. Implications of the findings for intentional/systematic writing instruction in preschool curricula are discussed.     

On the global knowledge components in an information security curriculum–a multidisciplinary perspective

Because of the borderless feature of the Internet, information security threats could come from anywhere around the globe. In this research, we propose adding global knowledge components in the information security curriculum using a multi-disciplinary approach. We argue that a global perspective has been lacking in the current information security curriculum. We then propose several knowledge components to be added in the curriculum to enhance the global perspective. We also examine how to incorporate knowledge from various related disciplines, including political science, criminal justice, and business administration. Through our empirical study on faculty from various disciplines and the industry practitioners with first-hand information security knowledge, we confirm that the proposed knowledge components are relevant to the information security education and practice. Analyzing the similarities and differences among responses from various disciplines, we also found that albeit different disciplines have slightly different emphases on the curriculum components, they all tend to agree on the importance of adding the global perspectives in information security education. Our research could be of value to the educators in the information security field when considering incorporating a global perspective into the curriculum. It could also shed some lights when examining the relevance of global information security to various disciplines.     

PRESERVICE MATHEMATICS AND SCIENCE TEACHERS IN AN INTEGRATED TEACHER PREPARATION PROGRAM FOR GRADES 7–12: A 3-YEAR STUDY OF ATTITUDES AND PERCEPTIONS RELATED TO INTEGRATION

The purpose of this article is twofold: (a) to describe a unique teacher licensure program for grades 7–12 that integrates mathematics, science, and technology education and (b) to explore the attitudes and perceptions related to the integration of mathematics, science, and technology education of three cohorts of preservice teachers enrolled in the first 3 years of the program. Eighty-one preservice teachers responded to a semantic differential to measure attitudes and perceptions related to “mathematics, science, and technology education integration.” Principal components and internal consistency reliability analyses were computed to provide validity and reliability evidence. Preservice teachers also responded to one open-ended, free-response written question, “What does the integration of mathematics, science, and technology education mean to you?” Multivariate and univariate analyses of variance with repeated measures and Pearson cross-tabulation chi-square analyses were computed to identify pretest–posttest differences for the value and difficulty scales, identified by the principal components analysis. Analytic inductive methods were used to identify emergent themes in student written responses to the open-ended question. Results indicated no change in preservice teacher attitudes and perceptions related to the value of integration—they clearly valued integration at the onset and completion of the program, often citing student benefits. However, a significant change in preservice teacher attitudes and perceptions related to difficulty was noted. Upon completion of the program, preservice teachers perceived integration to be more difficult and identified barriers and challenges—demonstrating a more realistic, practical, and cautious approach to the integration of mathematics, science, and technology education.     

Speaking ‘over’ performativity

In a time where standards and accountability override trust in teachers and principals, mandated versions of pedagogy have recently appeared in the Australian landscape. This article critiques one pedagogical reform initiative and suggests that in performative times, it may be preferable for principals and teachers to speak ‘over’ reform than to speak ‘back’ to it. While reference to competency standards increasingly replaces discussion about professionalism, the argument is developed here that key elements of professionalism include trust, agency, identity and judgement, which are excluded from the standards discourse. The article proposes that the tenuous hold teachers have on professionalism might be strengthened by critical school leaders adept at navigating their way around performative demands and who encourage teachers to speak ‘over’ codes about appropriate behaviour to instead explore what it means to be a teacher professional.     

Prior knowledge, attitude, and strategy use in an introduction to statistics course

The present study used both quantitative and qualitative methods to investigate the learning and motivational strategies used by students in a beginning-level statistics course. The research questions that guided the investigation are: (1) Do motivational variables account for unique variance in the academic performance of statistics students? (2) Do deeper-level processing strategies account for unique variance in the academic performance of statistics students? (3) Do successful students report using different motivation and learning strategies than unsuccessful students in a beginning-level statistics course?     

A preliminary evaluation of the associations among functional performance tasks and quality of life in obese and healthy weight youth

The associations among lower extremity functional performance and quality of life in obese youth are unknown. The aims of this study were to compare lower extremity strength, lower extremity functional performance, and health related quality of life between obese and healthy-weight youth and evaluate the relationships between lower extremity performance and health related quality of life in obese youth. Twenty obese and 20 age and sex matched healthy-weight youth were recruited. Peak torque of the major lower extremity muscles were measured. Functional performance was measured with single leg hop and single leg balance tests. The Paediatric Quality of Life questionnaire's physical and psychosocial health subscales were used. Paired t-tests and multiple regression analyses were performed. Obese youth demonstrated decreased peak torque in all muscles measured (P < 0.05), poorer functional performance (P < 0.05), and worse physical health related quality of life (P < 0.05) compared to healthy-weight youth. Lower extremity functional performance was associated with aspects of quality of life in the obese group (P = 0.002), but not in the healthy-weight group (P < 0.05). These results may assist in encouraging best practices in the promotion of exercise, physical activity, and quality of life in obese youth.
