Designing Curriculum-Based Mathematics Professional Development for Kindergarten Teachers

This study examines the influence of a year-long mathematics professional development program on Kindergarten teachers’ beliefs, content knowledge, instructional practices, and their students’ achievement. The professional development program is grounded in the theoretical construct of learner-centered professional development and focuses on supporting teachers’ integration of standards-based pedagogies aligned with the Common Core State Standards in Mathematics. Data analysis included examining 15 Kindergarten teachers’ mathematics content knowledge, their beliefs about mathematics, their enactment of student-centered pedagogies, and student achievement on curriculum-based assessments. Findings indicated that teachers adopted more student-centered pedagogies and embraced more student-centered beliefs about mathematics teaching during their time in the project. Further, Kindergarten teachers also demonstrated gains in their mathematical content knowledge, and those content knowledge gains were linked to gains in student achievement.     

Effects of maze geometry and experience on exploratory behavior in the rat

Rats were exposed twice in a rotated sequence to a series of six mazes, consisting of hexagonal alleys, balanced for different alley length and structural complexity. Locomotor activity increased with alley length and decreased with structural complexity of the mazes. Locomotion became less stereotyped with increased experience, showing an increasing number of turns, less constant velocity, loss of the initial preference for outward leading alleys and weakening of the forward tendency at reentry from side alleys into hexagonal alleys. In contrast to these qualitative changes of locomotion, the amount of activity remained almost unchanged throughout the experiment. The results suggest that these increases in locomotion complexity depend upon complex interactions between experience and stimulus content of the mazes.     

A SPECIAL‐PURPOSE STUDIO

The paper describes the design and use of a studio system which arose out of the need to give demonstrations of experimental procedures to practical classes of up to 150 students. Since the requirements could be specified in some detail it was possible to use novel methods of working which turned out to be very efficient and economical.     

'Bad Days don't Kill You; They Just Make you Stronger': A case study of an early childhood educator's resilience

What enables some early childhood educators to sustain their commitment to a career in children's services despite multiple adverse conditions that lead to high rates of attrition from the field? The case study documented in this article seeks to address this question by identifying influences contributing to the resilience of an Australian early childhood educator. The findings highlight the importance of personal qualities, contextual features, and the interplay between the personal and the contextual. I conclude by suggesting that fostering resilience could contribute to efforts to address the escalating staffing shortfall in children's services in Australia and internationally. Qu'est-ce qui permet quelques e´ducateurs de la premie ¤ re enfance de soutenir leur engagement a ¤ une carrie ¤ re dans le service des enfants en de´pit des conditions contraires divers qui menent aux hauts taux d'attrition dans ce champ? L'e´tude de cas documente´e dans cet article cherche a ¤ adresser cette question en identifiant des influences contribuant a ¤ la re´sistance demontre´e par un e´ducateur Australien de la petite enfance. Les de´couvertes soulignent l'importance des qualite´s personnelles, les caracte´ristiques contextuelles, et l'interaction entre ce qui est personnel et ce qui constitue le contexte. Je conclus en sugge´rant que la stimulation de cette re´sistance pourrait contribuer aux efforts qui abordent une manque croissante de personnel dans les services des enfants dans l'Australie et dans le cadre international.

El caso documentado en este art L ´culo procura contestar esta pregunta identificando las influencias que contribuyen a la resistencia de un educador de la primera infancia australiano.

Perceived efficacy of teachers in Macao and their alacrity to engage with inclusive education

ABSTRACT

This paper reports findings of a mixed methods study examining private school teachers’ perceptions of efficacy in dealing with the challenges presented by inclusive education in Macao. This is highly pertinent after the Government invited consultation to propose changes to amendments of the Decree Law of 1996 concerning the education of students with Special Education Needs (SEN) which will likely see private schools being required to accept these students in the future. Within the context of teacher preparedness for inclusive education, the study found that a number of teachers felt that they were not at all prepared to teach students with SEN. Whilst some teachers suggested that they lacked skills and knowledge in teaching in inclusive classrooms, some felt overwhelmed with the challenges. The teachers proposed that they would need to know how to provide instructional adaptations and modifications to support students with SEN. Implications for continuous development of teacher training and education are discussed within the context of improving teacher efficacy and how private school teachers could better respond to the challenges of inclusive education in Macao.     

Optimal Design for Two-Level Random Assignment and Regression Discontinuity Studies

An important concern when planning research studies is to obtain maximum precision of an estimate of a treatment effect given a budget constraint. When research designs have a multilevel or hierarchical structure changes in sample size at different levels of the design will impact precision differently. Furthermore, there will typically be differential costs of enrolling additional units at different levels of the hierarchy. The optimal design problem in multilevel research studies involves determining the optimal sample size at each level of the design given specified design parameters and a specified marginal cost of recruitment at each level. The current work extends existing results by considering optimal design for (a) unbalanced random assignment designs and (b) regression discontinuity designs.     

The perception of smiling and its experiential correlates in three-month-old infants

We studied individual differences in 3-month-olds' perceptions of smiling and the experiential correlates of those differences. In the laboratory, infants saw a graduated series of smiles that grew in intensity of expression. As a group, 3-month-olds preferred increasingly intense expressions of smiling, but individually they showed different growth rates of preference across the smiling series. Further, infants' preferences related to their home experiences: Infants who showed greater sensitivity to smiling had mothers who more frequently encouraged attention to themselves when they were smiling and their infants were looking at them. Infant discrimination within and between categories of facial expression and the relative strengths of association between different kinds of naturally occurring experiences and infant perceptual sensitivity are discussed.
