In a daily time–place learning task,time is only used as a discriminative stimulus if each daily session is associated with a distinct spatial location

It is difficult for rats to acquire daily time–place (TP) learning tasks. One theory suggests that rats do not use time of day as a stimulus signaling a specific response. In the present study, we tested rats’ ability to use time of day as a discriminative stimulus. A fixed-interval procedure was used in which one lever provided reinforcement on a FI-5-s schedule in morning sessions, and the same lever provided reinforcement on a FI-30-s schedule in afternoon sessions. Because only one place was used in this paradigm, the rats could only use time of day to acquire the task. Mean responses during the first 5 s of the first trial in each session indicated that the rats did not discriminate between the two sessions. In Phase II, a different lever location was used for each of the two daily sessions, which meant that both spatial and temporal information could be used to acquire the task. The rats readily acquired the task in this phase, and probe trials indicated that the rats were using a combination of spatial and temporal information to discriminate between the two different trial types. When the spatial cue was removed in Phase III, rats no longer discriminated the two sessions, suggesting that time can only be used as a discriminative stimulus when each daily session is associated with a distinct spatial location.     

Using lotteries to evaluate schools of choice: Evidence from a national study of charter schools

This paper draws on data and experiences observing and analyzing school lotteries from the National Evaluation of Charter School Impacts (Gleason et al., 2010) to describe the challenges associated with lottery-based research. In that study, covering 36 charter middle schools in 15 states, we found that charter schools did not affect student achievement or behavior on average, although there was substantial variation across schools. In this paper, we discuss the prevalence of oversubscribed charter schools at the time the study was conducted (the 2005–2006 and 2006–2007 school years), which was lower than commonly reported. We then describe how the sample of schools that participated in the study compared to all other charter middle schools nationwide, to provide some insight into the generalizabilty of findings from lottery-based studies. In general, oversubscribed charter schools were more likely to be located in urban areas and serve a higher-achieving population of students than those without excess demand. We also describe common features of school lotteries and waitlists, and examine implications of these features for a school's ability to support a lottery-based study. Finally, we summarize lessons learned for conducting lottery-based research on charter schools, drawing on our observations of the schools’ lotteries and analysis of the data from these lotteries.     

Mothers’ and fathers’ parenting styles and associations with toddlers’ externalizing,internalizing, and adaptive behaviors

The two primary objectives of the present study were to (a) investigate mothers’ and fathers’ reports of their own as well as their partner's parenting styles, and (b) assess how mothers’ and fathers’ parenting styles uniquely and jointly predicted toddlers’ externalizing, internalizing, and adaptive behaviors. Fifty-nine mothers and fathers independently completed the Parenting Styles and Dimension Questionnaire (PDSQ; Robinson, Mandleco, Olsen, & Hart, 2001) and the Behavior Assessment Scale for Children-2 (BASC-2; Reynolds & Kamphaus, 2004). Parents’ self-reports of their parenting styles were positively correlated with each other for all three parenting styles (authoritative, authoritarian, and permissive). Comparisons between parents’ reports of their partner's styles with that of the partner's self-reports were positively and moderately correlated for all three parenting styles. Findings revealed mothers’ and fathers’ self-reported parenting styles explained 44% of the variance in youngsters’ externalizing behaviors. In particular, permissive parenting by mothers and authoritarian parenting by fathers uniquely and significantly predicted toddlers’ externalizing behaviors, while authoritative paternal parenting was predictive of adaptive behaviors.     

Work Calling: Exploring the Communicative Intersections of Meaningful Work and Organizational Spirituality

In the present study, we first describe three themes from the interdisciplinary literature: sacred and secular variations; calling as historically and culturally situated; and potential benefits, alienation, and marginalization. Second, through a thematic analysis (Owen, 1984) based on participant data, we examine how participants’ understanding and interpretation of work calling as an overarching meaningfulness, a combination of personal passion and skill set, and a contribution to society serve as definitional makers. We argue that these findings emphasize the processural and constitutive nature of work calling. We conclude by highlighting the communicative dimensions of work calling as they may contribute to future critical and empirical work, noting the possibilities for sense-making theory to intervene in this interdisciplinary area of inquiry.     

The role of constructivist educational software on students’ learning regarding mechanical interaction

This paper mainly describes the role of the multimedia software package ‘Interactions between Objects’ on students’ learning of mechanical interaction forces and Newton’s laws. We designed and developed this software within social constructivism on the basis of 226 students’ initial conceptions (categorized in six categories), in order to help students construct appropriate knowledge about the subject. Teaching with the software was conducted in 13 primary, lower secondary and upper secondary school classes. In the software’s evaluation research 226 students (aged 11–16) and 13 teachers of the classes participated. Data analysis showed students’ substantial learning gains with respect to their initial alternative conceptions of the six conceptual categories. Particularly, the students’ incorrect answers to the post-test questionnaire have perceptibly decreased (a mean of 65%). In contrast, their correct answers to the questions reached high percentages, from 60% to 90% depending on the question and the students’ age. Also the teachers’ opinions and comments enhanced software’s evaluation. The contribution of the software’s specific characteristics on students’ learning is discussed along with implications for designing constructivist science learning tools.     

‘Opening up’ a science task: an exploration of shifting embodied participation of a multilingual primary student

Culturally and linguistically diverse (CLD) students have different home languages and cultures from many of their peers, In our context, these students suffer from higher school drop-out rates than their peers and are far behind their peers in sciences. This study investigates the interactions of a nine-year-old child whose home language is Portuguese and who learns science in this specific case in a diglossic environment in the Luxembourgish school system, in which his teacher used German for written tasks and Luxembourgish for oral communication. We examine, moment-by-moment, the interactions around a task regarding environmental protection. The role of this Lusoburguês (Luxembourgish and Portuguese identities and nationalities combined) student and his embodiment and participation changes when his group is confronted with an activity that requires an increased amount of manipulation. His identity evolves in interaction, as he becomes the leader in his group, and through a playful stance, manages to open the task so that his peers can further explore. Implications include the value of including more open-ended investigations in the teaching and learning of science as well as implications for further study concerning practice-based approaches in science classrooms with CLD students, particularly in increasingly multilingual/cultural and/or diglossic or heteroglossic school contexts.     

Singaporean Early Childhood Teachers' beliefs about Literacy Development in a Multilingual Context

It is widely recognised that teachers' pedagogical practices are influenced by many factors, including their personal experiences, their theoretical knowledge and the institutional context in which they work. Yet little is known about the beliefs held by Singaporean teachers about language and literacy development. Given the significance of early childhood for subsequent academic achievement, this study employed a survey method to explore the beliefs about literacy held by 79 teachers of 4‐ to 6‐year‐old children in prior‐to‐school settings. The findings indicate that almost all teachers viewed their primary goal as fostering children's ability to communicate and express themselves. They believed in using an eclectic approach rather than focusing on one or other ‘method’. The findings have implications for early childhood teacher education programs, professional development and implementation of Government policies in Singapore.     

The importance of mature,part-time students to higher education in the U.K.

This paper assesses the contribution made by mature part-time students to the statistics on higher education. It shows that part-time numbers currently account for approximately 40% of total student numbers in the UK, 33% of university students, (mostly in the Open University) and 43% of the total in polytechnics and colleges, (1989–90 figures). The majority are mature people, over 25 years of age, who combine both education and employment. The principal change over the past ten years has been the increasing proportion of women, who now form more than 44% of the total number of students and 42% of the part-time total. A theoretical analysis is carried out, using the Human Capital model, which shows that part-time higher education might produce significant rates of return, both to the individual and society. It is noted that most of the research efforts in the UK, into the benefits of higher education, have concentrated on young, 18–21 year olds, who study full-time, and that current government policy is primarily concerned with improving the participation rate of this age group. This paper concludes that there is sufficient evidence to warrant a more thorough investigation of the costs and benefits of part-time study and suggests that there is considerable potential for expansion in this area.     

Critical Literacy,Disciplinary Literacy: Reading the Engineering-Designed World

Globally, many people spend most of their time interacting with the products of engineering design as they wear clothes, drink clean water, use transportation systems, and more. Given the omnipresence of engineering design, whose material results are felt daily in people’s lives, it seems especially important that students learn to recognize and question how certain designs promote the welfare and interests of some while remaining inaccessible to others. In this article, we outline a vision for critical literacy instruction in engineering that simultaneously incorporates and challenges professional standards. We—an associate professor of literacy, an engineer, and a teacher at an engineering-focused high school—illustrate how critical literacy instruction might be enacted in the context of engineering design instruction in high schools. We describe how critical literacy can complement disciplinary literacy instruction in engineering as students use critically-focused, disciplinary lenses to move toward social justice.     

Impacts of a Prekindergarten Program on Children's Mathematics,Language, Literacy,Executive Function,and Emotional Skills

Publicly funded prekindergarten programs have achieved small‐to‐large impacts on children's cognitive outcomes. The current study examined the impact of a prekindergarten program that implemented a coaching system and consistent literacy, language, and mathematics curricula on these and other nontargeted, essential components of school readiness, such as executive functioning. Participants included 2,018 four and five‐year‐old children. Findings indicated that the program had moderate‐to‐large impacts on children's language, literacy, numeracy and mathematics skills, and small impacts on children's executive functioning and a measure of emotion recognition. Some impacts were considerably larger for some subgroups. For urban public school districts, results inform important programmatic decisions. For policy makers, results confirm that prekindergarten programs can improve educationally vital outcomes for children in meaningful, important ways.
