Electronic Textbooks: Antecedents of Students’ Adoption and Learning Outcomes

Faculty and students are increasingly faced with the opportunity to use electronic versions of textbooks (e‐texts). Despite the advantages of e‐texts and recent advances in technology, evidence suggests that students are still reluctant to adopt and use e‐texts. This situation leads us to investigate two research questions: What factors contribute to students’ acceptance of e‐texts? Are there differences between hardcopy texts and e‐texts when it comes to course grade? We draw on a variety of perspectives (i.e., psychology, management information systems, economics, environmental studies) to build a framework that allows us to determine the motivations of students for adopting e‐texts, and the learning outcomes of e‐text adoption. Data was collected via a survey administered in the business school of a metropolitan university with approximately 20,000 students, located in the western United States. Results suggest that perceived ease‐of‐use and the price of e‐texts relative to hardcopy texts are two key motivators in e‐text adoption, while perceived usefulness, Internet self‐efficacy and environmental concerns are not significant motivators. However, there was no significant difference in the grades of e‐text adopters compared to hardcopy adopters. We conclude this paper by discussing the implications of our findings for educators.     

EVALUATION OF THE CLASS PASS INTERVENTION FOR TYPICALLY DEVELOPING STUDENTS WITH HYPOTHESIZED ESCAPE‐MOTIVATED DISRUPTIVE CLASSROOM BEHAVIOR

The aim of this study was to evaluate the Class Pass Intervention (CPI) as a secondary intervention for typically developing students with escape‐motivated disruptive classroom behavior. The CPI consists of providing students with passes that they can use to appropriately request a break from an academic task to engage in a preferred activity for preset amount of time. In addition, students are incentivized to not use the class passes by continuing to engage in the academic task and instead exchanging them for a preferred item or activity. Using an experimental single‐case withdrawal design with replication through a concurrent multiple‐baseline across‐participants design, the CPI was shown to reduce disruptive behavior and increase academic engagement in three students who engaged in hypothesized escape‐motivated behavior. Results also revealed that the effects of the CPI were maintained at a two‐week follow‐up probe and consumers found it to be acceptable. The limitations and implications of the findings for future research on effective classroom‐based interventions are discussed.     

Technopolicing,surveillance, and citizen oversight: A neorepublican theory of liberty and information control

In modern society, we see the struggle to balance the proper functioning of government with the interests and rights of the people to access government information playing out all around us. This paper explores the relationship between liberty and security implicated by government surveillance and citizen-initiated efforts to cast the gaze back at the government (so-called “reciprocal surveillance”). In particular, this paper explores how a neorepublican conception of political liberty, defined as the absence of the possibility of domination, can inform future information policy research in this area. The paper concludes that, to be fully non-dominating, government must respect and provide effective institutional and legal mechanisms for their citizenry to effectuate self-government and command noninterference. Establishing liberal access rights to information about government conduct and mechanisms that ensure that citizens can effectively command noninterference are justified on the grounds that they reduce the possibility of arbitrary, and actual, interference with the right of the people govern themselves.     

The nature of counselling: An investigation of counselling activity inselected countries

The purpose of this study was to investigatecounselling as a process. It was conducted toexplore whether counselling is available invarious countries, even if it is known byanother name. This study examined the kinds ofhelp available to people with specificdifficulties. It sought to discern whether theways of helping include activities that mightbe thought of as counselling. As a way todiscover what forms of help might be availableto people in a given country, a series ofstressful incidents confronting one family ofaverage income living in a large town weredeveloped into a questionnaire format. Theseincidents were designed to stimulate thinkingand focus attention on possible help-givingsources. Data were collected from sources infifteen countries through interviews atinternational counselling conferences and withselected embassy officials in Washington, D.C.Interviews were also conducted in the UnitedKingdom, the United States, Costa Rica, andMalaysia. In addition, questionnaires were sentto experts knowledgeable about social welfareissues in a number of countries. The findingsfrom this investigation suggest thatcounselling as an activity or a process may betaking place under different names in differentcultures.     

Exploring preservice elementary teachers’ critique and adaptation of science curriculum materials in respect to socioscientific issues

The work presented here represents a preliminary effort undertaken to address the role of teachers in supporting students’ learning and decision-making about socioscientific issues (SSI) by characterizing preservice elementary teachers’ critique and adaptation of SSI-based science curriculum materials and identifying factors that serve to mediate this process. Four undergraduate preservice elementary teachers were studied over the course of one semester. Results indicate that the teachers navigated multiple learning goals, as well as their own subject-matter knowledge, informal reasoning about SSI, and role identity, in their critique and adaptation of SSI-oriented science instructional materials. Implications for science teacher education and the design of curriculum materials in respect to SSI are discussed.     

Elementary teachers’ use of content knowledge to evaluate students’ thinking in the life sciences

Science learning environments should provide opportunities for students to make sense of and enhance their understanding of disciplinary concepts. Teachers can support students’ sense-making by engaging and responding to their ideas through high-leverage instructional practices such as formative assessment (FA). However, past research has shown that teachers may not understand FA, how to implement it, or have sufficient content knowledge to use it effectively. Few studies have investigated how teachers gather information to evaluate students’ ideas or how content knowledge factors into those decisions, particularly within the life science discipline. We designed a study embedded in a multi-year professional development program that supported elementary teachers’ development of disciplinary knowledge and FA practices within science instruction. Study findings illustrate how elementary teachers’ life science content knowledge influences their evaluation of students’ ideas. Teachers with higher levels of life science content knowledge more effectively evaluated students’ ideas than teachers with lower levels of content knowledge. Teachers with higher content exam scores discussed both content and student understanding to a greater extent, and their analyses of students’ ideas were more scientifically accurate compared to teachers with lower scores. These findings contribute to theory and practice around science teacher education, professional development, and curriculum development.     

Recreating blood-brain barrier physiology and structure on chip: A novel neurovascular microfluidic bioreactor

The blood-brain barrier (BBB) is a critical structure that serves as the gatekeeper between the central nervous system and the rest of the body. It is the responsibility of the BBB to facilitate the entry of required nutrients into the brain and to exclude potentially harmful compounds; however, this complex structure has remained difficult to model faithfully in vitro. Accurate in vitro models are necessary for understanding how the BBB forms and functions, as well as for evaluating drug and toxin penetration across the barrier. Many previous models have failed to support all the cell types involved in the BBB formation and/or lacked the flow-created shear forces needed for mature tight junction formation. To address these issues and to help establish a more faithful in vitro model of the BBB, we have designed and fabricated a microfluidic device that is comprised of both a vascular chamber and a brain chamber separated by a porous membrane. This design allows for cell-to-cell communication between endothelial cells, astrocytes, and pericytes and independent perfusion of both compartments separated by the membrane. This NeuroVascular Unit (NVU) represents approximately one-millionth of the human brain, and hence, has sufficient cell mass to support a breadth of analytical measurements. The NVU has been validated with both fluorescein isothiocyanate (FITC)-dextran diffusion and transendothelial electrical resistance. The NVU has enabled in vitro modeling of the BBB using all human cell types and sampling effluent from both sides of the barrier.     

Distributed Scaffolding in a Service-Learning Course

This article argues that the instructional scaffolding metaphor may be reconceived as distributed scaffolding when multiple means of influence are provided in a service-learning setting. In the service-learning course described here, the professor's role is largely as designer of activity settings for preservice teacher candidates, through which the students construct their own conceptions of teaching culturally diverse populations. The course involves a set of interrelated settings: a tutoring experience at the city's alternative high school; the reading of books from a menu of texts that cover a range of diversity topics; the discussion of these books in book club meetings independent of the professor's direct influence; and the whole-class discussion of these texts, led by each student book club. The distributed nature of the course scaffolding is illustrated with an excerpt from one book club's discussion.     

The Uncanny Valley: The Effects of Rotoscope Animation on Motivational Processing of Depression Drug Messages

The purpose of this study was to investigate how rotoscope animation affects cognitive and emotional processing of depression drug ads. A 2 (animation) × 2 (position of tone) × 4 (message) experiment was conducted. Participants (N = 100) viewed 4, 90-s messages. STRTs (secondary task reaction times) and self-report of emotional responses were collected. Participants also completed an audio recognition task following each message. Among the key findings from this study were that participants in the animated condition showed signs of cognitive withdrawal and descent into a defensive cascade reflective of increasingly fast STRTs and poor encoding of drug side effects.
