Using digital images of the zebra finch song system as a tool to teach organizational effects of steroid hormones: a free downloadable module

Zebra finch song behavior is sexually dimorphic: males sing and females do not. The neural system underlying this behavior is sexually dimorphic, and this sex difference is easy to quantify. During development, the zebra finch song system can be altered by steroid hormones, specifically estradiol, which actually masculinizes it. Because of the ease of quantification and experimental manipulation, the zebra finch song system has great potential for use in undergraduate labs. Unfortunately, the underlying costs prohibit use of this system in undergraduate labs. Further, the time required to perform a developmental study renders such undertakings unrealistic within a single academic term. We have overcome these barriers by creating digital tools, including an image library of song nuclei from zebra finch brains. Students using this library replicate and extend a published experiment examining the dose of estradiol required to masculinize the female zebra finch brain. We have used this library for several terms, and students not only obtain significant experimental results but also make gains in understanding content, experimental controls, and inferential statistics (analysis of variance and post hoc tests). We have provided free access to these digital tools at the following website: http://mdcune.psych.ucla.edu/modules/birdsong.     

Conceptualizing curriculum management in an effective secondary school: a Western Australian case study

ABSTRACT

This paper investigates the linkages between management processes and the curriculum using an academically effective secondary school as a case study. The aims of the study are twofold. First, in view of the acknowledged importance governments and others place on the quality of school leadership and management on the one hand and curriculum, teaching and learning reforms on the other, there is a need for empirical data as to how school leaders and managers work to secure improvements in curriculum, teaching and learning. This study purports to provide such data. The second aim acknowledges the need to develop conceptual frameworks and data collection instruments as aids to better understanding of complex relationships within school organizations.two deputy principals do play an indirect and important part in promoting academic performance by reinforcing school values in a wide variety of ways. Third, curriculum management is the responsibility of senior teachers and there is tight linkage between both senior teachers and teachers and high quality teaching and learning. Finally, the loose linkage between departments, and also between departments and senior management, provides little opportunity for a school‐wide approach to curriculum matters. It is evident that a whole‐school curriculum management perspective is absent in this school.     

Integrating reading and science education: On developing and evaluating WEE Science

Two studies of a new science programme called WEE Science were conducted in two fifth-grade classrooms. The studies lasted for seven days in one of the classrooms and nine days in the other. At the beginning of the programme the students chose a science trade book from among the many that were selected and brought to the classroom. The students then formed groups based on the topics of the books and asked questions (Wondering) about the content. After choosing one of the 'wonderments' to pursue further, the students formed and implemented a plan for investigating (Exploring). In each classroom, each student explored, working in cooperating groups of two or more. The students then explained (Explaining) to a group of their peers what they had wondered and what and how they had explored. The students' wonderments, activities, plans, and explanations were recorded in a science notebook that had been designed for that purpose. In addition, the classrooms were videotaped while WEE Science was in progress. While the studies were successful in that most students eagerly participated in all phases of the project, some problems were encountered which created another round of wondering for the researchers. Some of these were: evaluating students' work, responding to science misconceptions of students, teaching some students to record observations in their notebooks, deciding where WEE Science would fit best in the curriculum, and anticipating its reception in the science education community.     

Teachers' self‐assessment of the effects of formative and summative electronic portfolios on professional development

This study compared the effects of four electronic portfolio curricula on pre‐service and beginning teachers' self‐ratings of their professional development (n = 207), using a 34 item electronic Portfolio Assessment Scale (ePAS). Three formative portfolios, A, C and D, had teacher development as a primary objective and used participants' narrative reflections on students over a 2–3 month period. One summative portfolio, B, assessed teacher accountability through participants' analyses of professional teaching standards concerning students during 1–2 week teaching units. Factor analyses of the ePAS assessments for each portfolio and all four combined yielded the same five factors concerning professional outcomes: overall teacher development, including reflective skill (F1), an understanding of assessment roles (F2), an understanding of backwards planning (F3), the benefit of analyzing student work (F4) and the benefit of teacher peer collaboration (F5). For F1, F3 and F5 the means of the formative portfolios A, C and D were significantly higher than those of portfolio B. No differences were found among the portfolios concerning the benefits of analyzing student work (F4). The researchers concluded that formative portfolios that focused on teacher development better supported professional outcomes than did the summative accountability portfolio. It was concluded that portfolios should not be used for the summative accountability of teachers.

Dans cette étude nous avons comparé les effets de quatre programmes scolaires à portefeuille électronique sur les autocritiques que des enseignants débutants ont faites de leur développement professionnel (n = 207). Nous nous sommes servis d'une échelle d'évaluation à portefeuille électronique de 34 points (ePAS). L'objectif principal des trois portefeuilles formatifs A, B et D était le développement de l'enseignant. Pour y parvenir nous avons employé des réflexions narratives sur les élèves pendant une période de deux à trois mois. A travers un portefeuille sommaire, B, nous avons évalué la responsabilité des enseignants au moyen des analyses que les participants ont faites des normes de l'enseignement professionnel des unités d'apprentissage d'une à deux semaines. Nous avons conclu que les portefeuilles formatifs qui se concentraient sur le développement des enseignants ont mieux soutenu le rendement professionnel des jeunes enseignants.

Este estudio compara los efectos de cuatro portafolios electrónicos curriculares sobre las auto evaluaciones de profesores antes de que comiencen a ejercitar la enseñanza y de profesores que inician su desarrollo profesional (n = 207), utilizando 34 ítemes de la escala de Portfolio Assessment (Valorización de Portafolios) (ePAS). Tres portafolios formativos, A, C y D, tienen como objetivo principal el desarrollo de la enseñanza usando las reflexiones por escrito de los participantes sobre estudiantes en un período de dos a tres meses. En un portafolio de síntesis, B, se valora la responsabilidad de los profesores. Durante una unidad educacional de una a dos semanas, los participantes evalúan métodos de enseñanza y, a través de este análisis, valoran la responsabilidad de los profesores. Se concluye que los portafolios formativos que se enfocan en el desarrollo de la enseñanza facilitan de mejor manera el resultado del desarrollo de los profesionales jóvenes.

Diese Arbeit vergleicht die Wirkungen von vier Lehrplänen im Bereich elektronischer Portfeuilles auf die beruflichen Selbstbewertungen von werdenden und neueingetretenen Lehrkräften. Verwendet wird ein elektronisches Portfeuillewertungssystem (ePAWS) von 34 Punkten. Die Entwicklung der Lehrer ist die primäre Absicht von drei formativen Portfeuilles, A, C und D, in denen die Teilnehmer ihre Selbstbeobachtungen über zwei bis drei Wochen aufgeschrieben haben. Die Verantwortlichkeit von Lehren wird in einem zusammenfassenden Portfeuille B eingesschätzt, durch eine Beurteilung von lehrberuflichen Maßstaben der Teilnehmer in Bezug auf Studenten im Verlauf einer ein‐ bis zweiwöchigen Lehreinheit. Bewiesen wurde, daß die formativen Portefeuilles, die sich auf Lehrentwicklung konzentrierten, die Weiterentfaltung von neueingestiegenen Lehrkräften besser fördern.     

The Management of Dilemmas in School Restructuring: A case analysis

While there is growing interest in studying principals' perceptions of their work lives in terms of dilemmas, relatively few studies have gone beyond this to investigate how leaders manage and cope with such 'intractable' situations and the consequential effects and outcomes. Accordingly, this article provides an in-depth qualitative case study of the dilemmas faced by a principal who is involved in the restructuring of his school. It then analyses the ways in which he manages and copes with these intractable situations, and the effects and outcomes that result. The article begins by outlining a framework used in the analysis. It addresses some considerations of method, before describing relevant school and system contexts. Finally, the in-depth case study is presented using the structure associated with the framework described earlier. Among the key findings are that dilemmas present opportunities as well as challenges for visionary, proactive and creative school leaders.     

Explaining the Success of the World’s Leading Education Systems: The Case of Singapore

International comparative data on student performance has led McKinsey&Company, among others, to suggest that education systems will inexorably converge in their developmental trajectories with principals and schools enjoying more autonomy. This article challenges these assumptions through referencing Singapore where schools and professionals are still tightly controlled in key resources, curricula and assessment, and where other key factors contribute to its success – thereby evidencing multiple pathways to success.     

Major Differences: Variations in Undergraduate and Graduate Student Mental Health and Treatment Utilization Across Academic Disciplines

This article explores variations in mental health and service utilization across academic disciplines using a random sample of undergraduate and graduate students (N = 64,519) at 81 colleges and universities. We report prevalence of depression, anxiety, suicidality, and self-injury, and rates of help-seeking across disciplines, including results from multivariate logistic regressions. We find significant variations: Students in humanities and art and design are significantly more likely to have mental health problems; and for students with apparent mental health problems, treatment rates are lowest among those in business and engineering. Noting these variations could enhance efforts to promote student mental health, particularly within academic departments.     

Dopaminerge Modulation striataler Plastizität

This article attempts to outline the neuronal foundations of movement automatization. In particular, it is shown that an increase in automaticity corresponds to processes of synaptic plasticity in the corticostriatal and corticocortical system. This mechanism is supposed to induce changes in the neuronal representations of the respective skill. Furthermore, the role of phasic dopamine release will be discussed with respect to its modulating effect on processes of plasticity.
