Preservice Teachers’ Images of Scientists: Do Prior Science Experiences Make a Difference?

This article presents the results of a mixed methods study that used the Draw-a-Scientist Test as a visual tool for exploring preservice teachers’ beliefs about scientists. A questionnaire was also administered to 165 students who were enrolled in elementary (K–8) and secondary (8–12) science methods courses. Taken as a whole, the images drawn by preservice teachers reflected the stereotype of a scientist as a man with a wild hairdo who wears a lab coat and glasses while working in a laboratory setting. However, results indicated statistically significant differences in stereotypical components of representations of scientists depending on preservice teachers’ program and previous science experiences. Post degree students in secondary science methods courses created images of scientists with fewer stereotypical elements than drawings created by students in the regular elementary program.     

The Process of Fostering Consultee Development During Instructional Consultation

This investigation examines how the process of instructional consultation (IC) supports consultees' problem-solving and fosters change in how the consultees understand pertinent work problems. The setting was a mid-Atlantic elementary school's Instructional Consultation Team, and the participants were 13 case manager consultants and 5 teacher consultees. A micro-ethnographic research approach was used and 4 primary sources of data collected: interviews, direct observations, consultation documents, and IC training documents. Analysis of the data uncovered 4 general themes related to the participants' problem-solving and evolving understanding of the work issues. In the discussion, the question of how IC is a constructive process that promotes consultees' development is considered.     

Educational Support for Saudi Students with Learning Disabilities in Higher Education

Disability laws in Saudi Arabia mandate that higher education institutions provide support for special needs learners in order to ensure educational opportunities equivalent to opportunities for their nondisabled peers. These institutions experience challenges, however, in providing the necessary support to undergraduate and postgraduate students with learning disabilities (LDs). We conducted an exploratory study to assess educational support requirements and affordances for undergraduate and postgraduate students with LDs attending institutions of higher education in Saudi Arabia. We completed semistructured interviews with 22 special needs learners diagnosed with a LD (16 undergraduate and six postgraduate). The findings suggest that additional support services are needed for undergraduate and postgraduate students with LDs attending Saudi institutions of higher education.     

Juggling a New Format with Existing Tools: Incorporating Streaming Video into Technical Services Workflows

ABSTRACT

The University of Northern Colorado (UNC) Libraries have experienced a surge in streaming video requests in the past few years. Like others, UNC’s Technical Services department has found new ways to manage procedures and workflows associated with this format. This session covered the experiences and strategies of the presenters for handling streaming video databases, licensed content ripped from DVD, firm orders, and multiyear streaming licenses.     

Potentiation of responding on a VR schedule by a stimulus correlated with reinforcement: Effects of diffuse and localized signals

In Experiment 1, rats were trained to leverpress on a variable ratio (VR) 30 schedule with a 500-msec delay between the reinforced response and food delivery. Subjects that experienced a signal during the delay responded faster than did control subjects that received the stimulus un-correlated with reinforcement. Higher response rates were obtained when the stimulus used to signal reinforcement was auditory rather than visual. Experiments 2 and 3 compared the effects of signaling reinforcement with either a localized or a diffuse light on responding maintained by VR schedules of reinforcement. Elevated response rates were observed with the diffuse stimulus, but the localized stimulus failed to produce such potentiation. Experiment 3 also examined the conditioned reinforcing power of localized and diffuse visual stimuli. These results are discussed with reference to (1) theories of selective association and sign tracking and (2) their implications for current theories of signaling reinforcement.     

Should the Simple View of Reading Include a Fluency Component?

The Simple View of Reading states that reading comprehension is the product of word recognition and listening comprehension. Whereas much research has focused on word recognition accuracy, recent attention has been directed toward word recognition fluency. The current study investigated whether a separate fluency component should be added to the Simple View of Reading. A battery of reading and language measures was administered to 604 children in second, fourth, and eighth grades. Approximately half these children had language and/or nonverbal cognitive impairments in kindergarten, but weighting procedures were used to reduce the potential bias this sampling characteristic may have entailed. Structural equation modeling was used to determine whether fluency accounted for unique variance in reading comprehension after controlling for word recognition accuracy and listening comprehension. Individual profile analyses were conducted to determine the number of individual participants who␣had poor fluency in the spite of good word recognition accuracy and listening comprehension. Results showed that fluency did not account for unique variance in reading␣comprehension and that few individuals had problems in fluency separate from word recognition accuracy or listening comprehension. Thus, it does not appear that a separate fluency component should be added to the Simple View of Reading.     

Going to Prison: The Effect of a Prison Tour on Students’ Attitudes Toward Punitiveness

The pedagogical approaches of a criminal justice education affect the attitudes and perceptions of those most likely to develop and administer criminal justice policies in the future. This study examines the effect of a prison tour on students’ understanding of prison and attitudes about punishment. Undergraduate criminal justice students were given a survey to assess their attitudes about prisons, prisoners, and alternative sanctions before and after a field trip to the Southern Ohio Correctional Facility. Post-survey responses showed changes in students’ perceptions regarding punitiveness, prisons, prisoners, and rehabilitation. We discuss this finding within the framework of the contact hypothesis, and we recommend including this type of first-hand exposure as part of a criminal justice curriculum.     

Visual Learning and the Brain: Implications for Dyslexia

ABSTRACT— The central and peripheral visual fields are structurally segregated in the brain and are differentiated by their anatomical and functional characteristics. While the central field appears well suited for tasks such as visual search, the periphery is optimized for rapid processing over broad regions. People vary in their abilities to make use of information in the center versus the periphery, and we propose that this bias leads to a trade-off between abilities for sequential search versus contemporaneous comparisons. The parameter of periphery-to-center ratio (PCR) describes the degree of peripheral bias, which evidence suggests is high in many people with dyslexia. That is, many dyslexics favor the peripheral visual field over the center, which results in not only search deficits but also (more surprisingly) talents for visual comparison. The PCR framework offers a coherent explanation for these seemingly contradictory observations of both deficit and talent in visual processing. The framework has potential implications for instructional support in visually intensive domains such as science and mathematics.
