Within and Across Language Predictors of Word Learning Processes in Dual Language Learners

This study investigated the relation between Dual Language Learners’ (N = 90) vocabulary and grammar comprehension and word learning processes in preschool (aged 3-through-5 years). Of interest was whether: (a) performance in Spanish correlated with performance in English within each domain; and (b) comprehension predicted novel word learning within and across languages. Dual-language experience was evaluated as a potential moderator. Hierarchical linear modeling revealed stronger predictive associations within each language than across languages. Across languages, results varied by experience and domain. Structural sensitivity theory suggests exposure to two languages heightens awareness of parameters along which languages vary and provides a framework for interpreting complex associations within and across languages. Knowledge from one language may influence learning in both.     

A Layered Approach to Critical Friendship as a Means to Support Pedagogical Innovation in Pre-service Teacher Education

In this article we describe and interpret how two distinct layers of critical friendship were used to support a pedagogical innovation in pre-service teacher education. The innovation, Learning about Meaningful Physical Education (LAMPE), focuses on ways to teach future teachers to foster meaningful experiences for learners in physical education. Critical friendship was applied in two ways: (1) the first two authors served as critical friends to each other as they taught their respective teacher education courses using LAMPE, and (2) the third author acted as a meta-critical friend, providing support for and critique of the first two authors’ development and enactment of the innovation. Over two years, data were gathered from reflective journal entries, emails, recorded Skype calls, and teaching observations. The two layers of critical friendship held significant benefits in advancing and supporting the development of the innovation while also contributing to the professional learning of all participants. Analysis of the first year’s data showed that we entered the critical friendship without thoroughly considering what we each hoped to give and take from the relationship or acknowledging the potential problems that might unfold. In the second year, guided by suggestions from our meta-critical friend, we took a more rigorous inquiry stance as critical friends, contributing contentious feedback and pushing each other beyond our personal and pedagogical comfort zones. This led to a noticeable improvement in our professional learning about teacher education practices and advanced the development of the LAMPE innovation.     

An Australian s Perspective of an American University

Since high school I have always wanted to study in a country other than my own. However my parents always informed me that it was too expensive. This was until luck turned my way one day while I was at university. My advisor called me and asked me to go and see him as soon as possible. I just knew it had to be good news. I could barely stand the suspense and went to his office with a nervous happiness in my tummy My advisor told me that I had been offered a scholarship to study at Central Washington Univers...     

Effect of a conspecific’s presence on deprived rats’ Performance: Social facilitation vs distraction/imitation

The present study investigated effects of (a) conspecific’s “mere presence” and (b) water deprivation on emission of dominant responses by rats. Zajonc (1965) suggests that a conspecific’s presence functions like a physiologically based drive in enhancing performance of dominant responses. Alternative interpretations suggest that a conspecific’s presence impairs performance by distracting the observer or eliciting imitation of “irrelevant” responses. The social facilitation vs distraction/imitation hypotheses were tested in a 2 by 2 design: Barpress-trained rats, deprived of water for 4 or 23 h, barpressed for water in the presence of a naive rat or alone. Results supported social facilitation theory: Performance was significantly higher when the conspecific was present rather than absent and when the responder was 23 h rather than 4 h deprived. In reconciling these data with conflicting results, it was suggested that degree of contact may be important in determining how a conspecific’s presence affects performance of dominant responses.     

The purpose, design and use of examples in the teaching of elementary mathematics

This empirical paper considers the different purposes for which teachers use examples in elementary mathematics teaching, and how well the actual examples used fit these intended purposes. For this study, 24 mathematics lessons taught by prospective elementary school teachers were videotaped. In the spirit of grounded theory, the purpose of the analysis of these lessons was to discover, and to construct theories around, the ways that these novice teachers could be seen to draw upon their mathematics teaching knowledge-base in their lesson preparation and in their observed classroom instruction. A highly-pervasive dimension of the findings was these teachers’ choice and use of examples. Four categories of uses of examples are identified and exemplified: these are related to different kinds of teacher awareness.
