Serpents and Sheep: The Harriman Expedition, Alaska, and the Metaphoric Reconstruction of American Wilderness

This article examines one mechanism for the radical change in public perception of wilderness. The published papers of the Harriman Expedition, a scientific expedition at the end of the nineteenth century, are used to illustrate a process that I call “metaphoric reconstruction.” I argue that conceptual metaphors are one of the tools through which texts and rhetorical contexts can be mutually transformative.     

Science and Mathematics Literacy: PISA for Better School Education

In this study, we explored how a teacher used a new mobile application that enables students to collect data inside and outside the classroom, and then use the data to create scientific explanations by using claim-evidence-reasoning framework. Previous technologies designed to support scientific explanations focused on how these programs improve students’ scientific explanations, but these programs ignored how scientific explanation applications can support teacher practices. Thus, to increase our knowledge about using mobile devices in education, this study aims to portray the synergy with an emphasis on a teacher’s practices when using mobile devices in 2 different units (water quality and plants). Synergy can be thought of as various scaffolds (scaffolds in the mobile application and the teacher support) working together to enable students to support creating explanations when using the mobile application. The findings of this study showed that the decrease in the teacher’s support for claims did not affect the quality of the students’ claims. On the other hand, the quality of students’ reasoning was linked with the teacher’s practices. This suggests that when supporting students’ explanations, focusing on components that students find challenging would benefit students’ construction of explanations. To achieve synergy in this process, the collaboration between teacher’s practices, professional development days, and scaffolds designed to support the teacher played a crucial role in aiding students in creating explanations.     

Addressing first- and second-order barriers to change: Strategies for technology integration

Although teachers today recognize the importance of integrating technology into their curricula, efforts are often limited by both external (first-order) and internal (second-order) barriers. Traditionally, technology training, for both preservice and inservice teachers, has focused on helping teachers overcome first-order barriers (e.g., acquiring technical skills needed to operate a computer). More recently, training programs have incorporated pedagogical models of technology use as one means of addressing second-order barriers. However, little discussion has occurred that clarifies the relationship between these different types of barriers or that delineates effective strategies for addressing different barriers. If pre- and inservice teachers are to become effective users of technology, they will need practical strategies for dealing with the different types of barriers they will face. In this paper, I discuss the relationship between first- and second-order barriers and then describe specific strategies for circumventing, overcoming, and eliminating the changing barriers teachers face as they work to achieve technology integration.     

Transition to Preschool Special Education: A Review of the Literature

Research Findings: Services to young children with disabilities and their families are provided through state and federal resources to those who meet eligibility requirements. This article reviews the literature that addresses the transition to preschool special education services occurring from the time a child reaches 2 years, 6 months, of age until the child's third birthday. Practice or Policy: We discuss the conceptual frameworks of transition, as well as the definition and requirements of transition, and factors affecting a smooth transition for young children and their families. We also present literature on transition practices such as technical assistance and collaboration, parent and family experiences, program quality, assistance for children and families, and policy considerations, as well as implications and recommendations for future research.     

‘Voice’, young people and action research

This article moves from an overview of what is meant by the term ‘voice’ to discussing the significance of its links with action research. It does this through using a simple typology of three types of voice: Authoritative, Critical and Therapeutic. Each type of voice represents a different process of articulation and intended outcome. It then moves on to consider ‘voice’ and the collaboration of young people in educational action research by unpicking a series of four assumptions which delineate major theoretical and practical possibilities and limitations. These assumptions provide a critique of the underpinning ideologies held by professionals when supporting and listening to young people     

L1 and L2 vocabulary glosses in L2 reading passages: Their effectiveness for increasing comprehension and vocabulary knowledge

This study investigated the effect of vocabulary glossing on recall and vocabulary learning, as well as learners’ preferences as to glossing. Eighty-five native speakers of English studying Spanish at the university level participated. Participants read a Spanish text under one of three treatment conditions: no gloss, English glosses, or Spanish glosses. They then were asked to write what they recalled of the passage, translate a list of the glossed vocabulary, and complete a questionnaire. The translation task was repeated four weeks later. Results showed that glossing did not significantly affect recall for the participants overall, but that those with higher than average proficiency recalled more if they had read a glossed version of the text. Those who had glosses outperformed their peers on the translation task administered immediately after they had read the text. However, this difference disappeared on the retest. Participants expressed preference for glosses, wished that they be located in the margin, and favoured Spanish glosses if they were comprehensible.
