Science and Mathematics Mentees and Mentors: Who Benefits the Most?

The purpose of our study was to determine the extent to which differences in a mentor model for science and mathematics teachers accounted for variances in mentoring effectiveness and persistence rates of teachers. School district designee, mentor, and teacher perceptions of mentoring support were collected through the use of interviews and surveys and analyzed using the grounded theory approach and open coding. Findings revealed that teachers and mentors recommended that future mentor models provide strong support and more face-to-face meetings. The most common change mentors made was that they incorporated new strategies into their teaching. Findings offer insight for structuring mentor models to increase effectiveness and persistence of teachers and build the capacity of mentors.     

Organizational effectiveness in education: Its measurement and enhancement

This study is concerned with the nature of organizational goals, and ways of measuring goal achievement. It is intended to provide administrators with some new ways of conceptualizing the evalution of effectiveness in educational systems. The paper points out the desirability of involving professionals in the setting of goals, proposes a three-tier system of goals for educational systems, and suggests some of the reasons for the frequent failure to achieve organizational goals. Additionally, a comprehensive approach to the goals of organizations, adapted from Gross's matrix of purposes, is proposed, on the grounds that only such an inclusive approach to organizational goals is entirely satisfactory. Finally, the paper takes issue with the notion that freedom for organization members equals absence of organizational controls. The sense of power for organization members increases with participation in control, as does effectiveness. Thus, particularly for organizations with large numbers of professionals as members, it is not absence of control but rather participation in control that is the vital factor in both freedom and effectiveness. The final conclusion of the paper is that attempts to improve the effectiveness of educational systems or institutions must be in the future more inclusive, and that the matrix of purposes approach is one possible line of development.

Résumé Cette étude porte sur la nature des objectifs des plans d'organisation et des méthodes servant à mesurer le degré de réussite dans la poursuite de ces objectifs. L'auteur se propose de fournir aux administrateurs un certain nombre de nouveaux critères pour concevoir l'évaluation de l'efficacité des systèmes éducatifs. Soulignant l'opportunité de confier à des professionnels l'établissement des objectifs, cette étude propose un système à trois paliers et tente d'expliquer les échecs fréquents auxquels aboutissent les objectifs des plans d'organisation. Par ailleurs, en ce qui concerne les objectifs des organisations, elle propose une attitude globale adaptée de l'étude de Gross intitulée matrix of purposes (matrice des objectifs), étant donné qu'une telle attitude est la seule qui soit satisfaisante à tous points de vue. Enfin l'auteur dénonce la notion selon laquelle la liberté accordée aux membres des organisations équivaut à une absence de contrôle sur ces dernières. En participant au contrôle de leurs organisations, les membres prennent en effet de plus en plus conscience de leur pouvoir et l'efficacité s'en trouve accrue. C'est ainsi que lorsqu'il s'agit, en particulier, d'organisations comptant de nombreux membres des professions libérales, ce n'est pas l'absence de contrôle mais plutôt la participation au contrôle qui représente le facteur capital à la fois de la liberté et de l'efficacité. En conclusion finale, cette étude affirme qu'à l'avenir, les tentatives d'amélioration des systèmes éducatifs ou des institutions devront avoir un caractère plus global et que la matrice des objectifs représente l'une des méthodes possibles à adopter dans ce domaine.

     

Blocking in eyelid conditioning: Effect of changing the CS-US interval and introducing an intertriai stimulus

Kamin’s three-stage blocking paradigm was investigated in rabbit eyelid conditioning, Two manipulations were examined. A change in the CS-US interval from Stage 1 to Stage 2 did not attenuate blocking. The introduction of a salient stimulus during the intertriai interval in Stage 2 also failed to attenuate blocking. The first result is not consistent with Kamin’s interpretation of the blocking effect in terms of US surprisingness. The second resuit is inconsistent with a prediction based on the Rescorla-Wagner model.     

How New Caledonian crows solve novel foraging problems and what it means for cumulative culture

New Caledonian crows make and use tools, and tool types vary over geographic landscapes. Social learning may explain the variation in tool design, but it is unknown to what degree social learning accounts for the maintenance of these designs. Indeed, little is known about the mechanisms these crows use to obtain information from others, despite the question’s importance in understanding whether tool behavior is transmitted via social, genetic, or environmental means. For social transmission to account for tool-type variation, copying must utilize a mechanism that is action specific (e.g., pushing left vs. right) as well as context specific (e.g., pushing a particular object vs. any object). To determine whether crows can copy a demonstrator’s actions as well as the contexts in which they occur, we conducted a diffusion experiment using a novel foraging task. We used a nontool task to eliminate any confounds introduced by individual differences in their prior tool experience. Two groups had demonstrators (trained in isolation on different options of a four-option task, including a two-action option) and one group did not. We found that crows socially learn about context: After observers see a demonstrator interact with the task, they are more likely to interact with the same parts of the task. In contrast, observers did not copy the demonstrator’s specific actions. Our results suggest it is unlikely that observing tool-making behavior transmits tool types. We suggest it is possible that tool types are transmitted when crows copy the physical form of the tools they encounter.     

Assessing collaborative learning: big data,analytics and university futures

Assessment in higher education has focused on the performance of individual students. This focus has been a practical as well as an epistemic one: methods of assessment are constrained by the technology of the day, and in the past they required the completion by individuals under controlled conditions of set-piece academic exercises. Recent advances in learning analytics, drawing upon vast sets of digitally stored student activity data, open new practical and epistemic possibilities for assessment, and carry the potential to transform higher education. It is becoming practicable to assess the individual and collective performance of team members working on complex projects that closely simulate the professional contexts that graduates will encounter. In addition to academic knowledge, this authentic assessment can include a diverse range of personal qualities and dispositions that are key to the computer-supported cooperative working of professionals in the knowledge economy. This paper explores the implications of such opportunities for the purpose and practices of assessment in higher education, as universities adapt their institutional missions to address twenty-first century needs. The paper concludes with a strong recommendation for university leaders to deploy analytics to support and evaluate the collaborative learning of students working in realistic contexts.     

A SYSTEMIC,STUDENT-CENTERED STUDY OF UNIVERSITY SERVICE

This paper discusses the methods and findings ofthe Student Focus Project, a sixmonth study of studentperceptions of service at a large university inBrisbane, Australia. The study paneled 24 focus groups of undergraduate students to assess theirbeliefs about a pretested set of questions concerningpositive and negative aspects of university life,successes and frustrations with university service,attempts to overcome the obstacles of university life,and what students expect from their relationship to theuniversity. Of the themes identified in the StudentFocus study, it was found that malignantbureaucracy and the balkanization ofInformation are systemic factors that negativelyinfluence student perceptions of the quality ofuniversity service. It was also found that studentstrategies for service recovery can contribute to the overall confusion andpoor performance of university services.

Learning science through writing: associations with prior conceptions of writing and perceptions of a writing program

Students in a large undergraduate biology course were expected to write a scientific report as a key part of their course design. This study investigates the quality of learning arising from the writing experience and how it relates to the quality of students’ preconceptions of learning through writing and their perceptions of their writing program that led to their report. Closed‐ended questionnaires investigating student conceptions and perceptions of writing, and approaches to writing, were completed by 121 students. Significant associations were found amongst qualitatively different prior and post conceptions of writing, approaches to writing and achievement. The results of the analyses suggest that the effective support of student experiences of writing reports requires teachers to be aware of the type of conceptions that students bring to their course and the perceptions they hold about the purpose of the writing program in which they are engaged.
