Professional Development for International Teachers: Examining TPACK and Technology Integration Decision Making

This mixed-methods study explored the impacts of a semester-long technology professional development for secondary school international teachers from developing nations around the world. We used (a) a survey approach to examine international teachers' perceived technology integration abilities using the technological pedagogical content knowledge (TPACK) framework and (b) a design task to understand their rationale behind technology integration decisions. As a group (N = 16), international teachers reported increased abilities in all TPACK domains. Qualitative analysis of their rationales revealed that though teachers learned to consider the affordances of technology, technology access issues were pivotal in their choice and use of technology in instruction planning. With education becoming increasingly global, the study has implications for the motivation and design of technology professional development programs for international teachers.     

Rats in a levered T-maze task show evidence of time–place discriminations in two different measures

It is difficult for rats to learn to go to an arm of a T-maze to receive food that is dependent on the time of day, unless the amount of food in each daily session is different. In the same task, rats show evidence of time–place discriminations if they are required to press levers in the arms of the T-maze, but learning is only evident when the first lever press is considered, and not the first arm visited. These data suggest that rats struggle to use time as a discriminative stimulus unless the rewards/events differ in some dimension, or unless the goal locations can be visited prior to making a response. If both of these conditions are met in the same task, it might be possible to compare time–place learning in two different measures that essentially indicate performance before and after entering the arms of the T-maze. In the present study, we investigated time–place learning in rats with a levered T-maze task in which the amounts of food varied depending on the time of day. The first arm choices and first lever presses both indicated that the rats had acquired time–place discriminations, and both of these measures became significantly different from chance during the same block. However, there were subtle differences between the two measures, which suggest that time–place discrimination is aided by visiting the goal locations.     

The Nature of Laboratory Learning Experiences in Secondary Science Online

Teaching science to secondary students in an online environment is a growing international trend. Despite this trend, reports of empirical studies of this phenomenon are noticeably missing. With a survey concerning the nature of laboratory activities, this study describes the perspective of 35-secondary teachers from 15-different U.S. states who are teaching science online. The type and frequency of reported laboratory activities are consistent with the tradition of face-to-face instruction, using hands-on and simulated experiments. While provided examples were student-centered and required the collection of data, they failed to illustrate key components of the nature of science. The features of student-teacher interactions, student engagement, and nonverbal communications were found to be lacking and likely constitute barriers to the enactment of inquiry. These results serve as a call for research and development focused on using existing communication tools to better align with the activity of science such that the nature of science is more clearly addressed, the work of students becomes more collaborative and authentic, and the formative elements of a scientific inquiry are more accessible to all participants.     

Executive Functioning and School Readiness Among Preschoolers With Externalizing Problems: The Moderating Role of the Student–Teacher Relationship

Research Findings: The objective of this study was to examine the student–teacher relationship as a potential moderator of the link between executive functioning (EF) and children’s early school readiness among a clinical sample of preschoolers with externalizing behavior problems (EBP). Participants for the study included 139 preschool children (75.54% boys, M age = 5.01 years, 84.94% Hispanic/Latino) with at-risk or clinically elevated levels of EBP. The student–teacher relationship was assessed using the Student–Teacher Relationship Scale. School readiness data were composed of standardized achievement test scores and teacher reports of kindergarten readiness. EF was measured via parent and teacher reports along with standardized measures of EF, including the Head–Toes–Knees–Shoulders task and 4 standardized subtests from the Automated Working Memory Assessment. Poorer student–teacher relationship quality was predictive of lower teacher-reported kindergarten readiness and higher academic impairment. Main effects were qualified by an interaction between EF and student–teacher relationship quality such that worse EF (parent/teacher reports and standardized performance) was only associated with lower teacher-rated kindergarten readiness for children with poorer student–teacher relationship quality. Practice or Policy: EF appears to be an important predictor of school readiness for preschool children with EBP, particularly for children experiencing poorer student–teacher relationships.     

Individual | collective dialectic of free‐choice learning in a community‐based mapping project

In this article we describe an instance of free‐choice learning in the context of an eelgrass mapping and stewardship project (the Project) that covers over 500 kilometers of coastline in British Columbia, Canada, and involves 20 volunteer groups. In this ethnographic case study we sought to (a) explicate the relationship between individual and collective learning in this free‐choice setting and (b) understand how a network of Project participants could both constitute a free‐choice learning setting and support such a setting. We articulate a dialectic relationship between individual and collective learning, which, unfortunately in our view, has not yet been explored in educational research. In this relation, collective learning fosters individual learning and vice versa, whereby individuals produce resources in action and as outcomes of their activities. These resources expand the action possibilities of the collective, and thus constitute learning. The stability of the network of Project participants, which brings about and supports collective and therefore individual learning, rests on the flexibility of the Project that enables local innovation and tailoring of mapping activities as well as access to expertise and tools produced by other groups and Project partners. The possibilities that arise in the Project for local people to participate in relevant ways constitute free‐choice learning settings.     

Mission matters: The cost of small high schools revisited

With the financial support of several large foundations and the federal government, creating small schools has become a prominent high school reform strategy in many large American cities. While some research supports this strategy, little research assesses the relative costs of these smaller schools. We use data on over 200 New York City high schools, from 1996 through 2003, to estimate school cost functions relating per pupil expenditures to school size, controlling for school output and quality, student characteristics, and school organization.We find that the structure of costs differs across schools depending upon mission—comprehensive or themed. At their current levels of outputs, themed schools minimize per pupil costs at smaller enrollments than comprehensive schools, but these optimally sized themed schools also cost more per pupil than optimally sized comprehensive schools. We also find that both themed and comprehensive high schools at actual sizes are smaller than their optimal sizes.     

The Potential to Develop a Career in Science: Young Women's Issues and Their Implications for Careers Guidance Initiatives

An exploratory study of career decision-making was conducted with young women in science, engineering, and technology programs in colleges, universities, and technical institutes. The participants described issues impacting on their continuation in their programs such as educational policies, levels of financial support, and the degree of gender equity expected and encountered. Difficulties with financial resources, institutional policies, and combining studying and working roles were recurrent themes. Family members and other role models and educational and work experiences were important influences in career decision-making. Recommendations for counselling to enhance the undergraduate experience and directions for future research are outlined.
