Infant Visual Attention and Stimulus Repetition Effects on Object Recognition

This study examined behavioral, heart rate (HR), and event-related potential (ERP) correlates of attention and recognition memory for 4.5-, 6-, and 7.5-month-old infants (N = 45) during stimulus encoding. Attention was utilized as an independent variable using HR measures. The Nc ERP component associated with attention and the late slow wave (LSW) associated with recognition memory were analyzed. The 7.5-month-olds demonstrated a significant reduction in Nc amplitude with stimulus repetition. This reduction in Nc was not found for younger infants. Additionally, infants only demonstrated differential LSW amplitude based on stimulus type on attentive trials as defined by HR changes. These findings indicate that from 4.5 to 7.5 months, infants’ attentional engagement is influenced by an increasingly broader range of stimulus characteristics.     

The celluloid ceiling: women academics,social expectations,and narrative in 1940s American film

This paper examines the portrayal of women university academics in American films from the 1940s. It applies analytical tools from a critical methodology to access the socio‐cultural ideas and values attributed to the female professoriate during what is a period of great change for women in American society. This analysis reveals that the values associated with the professors are aligned with the themes of chastity, sanctuary, and sacrifice in ways which portray them as other in the profession and society. Not only does this analysis illustrate the consequences and conditions of being a woman professor during the 1940s, but it also highlights the implications of these values for today’s female professoriate.     

Bringing Engineering Design into High School Science Classrooms: The Heating/Cooling Unit

Infusing engineering design projects in K-12 settings can promote interest and attract a wide range of students to engineering careers. However, the current climate of high-stakes testing and accountability to standards leaves little room to incorporate engineering design into K-12 classrooms. We argue that design-based learning, the combination of scientific inquiry and engineering design, is an approach that can be used to meet both K-12 educators’ and engineering advocates’ goals. This paper describes an 8-week high school curriculum unit, the Heating/Cooling System, in which engineering design is used to teach students central and difficult chemistry concepts such as atomic interactions, reactions, and energy changes in reactions. The goals of the paper are to (1) describe this successful design-based unit, (2) provide guidelines for incorporating design-based learning into other science topics, and (3) provide some evidence of its value for teaching difficult chemistry concepts and increasing interest in engineering careers.     

Full-day kindergarten and student literacy growth: Does a lengthened school day make a difference?

In the context of a quasi-experimental research design, literacy data obtained on students were examined to assess relationships between kindergarten program model (full- vs. half-day) and student literacy outcomes. Application of multilevel modeling techniques to the time series data collected from kindergarteners in economically disadvantaged school contexts in a large southwestern school district revealed that students exposed to a full day of instruction had greater literacy growth than their peers in half-day classrooms. Further examination of the program model results revealed that the relative efficacy of full-day kindergarten tended to be greater in smaller class size environments. These results, if replicated, suggest that full-day kindergarten initiatives targeted toward students from disadvantaged backgrounds may be more successful when implemented in classrooms with relatively small student enrollments. Implications for instructional policy and practice are discussed.     

Black-white IQ discrepancies may be related to differences in hemisphericity

WPPSI and McCarthy Scales subtests were ranked by members of the National Academy of Neuropsychology according to relative reliance on left-cerebral-hemisphere function. Pairs of blacks and whites matched for a variety of demographic variables were administered the WPPSI (132 pairs) and the McCarthy Scales (148 pairs). Difference scores were calculated, in standard score units, for each WPPSI and McCarthy subtest. A pattern of positive correlation occurred between the size of black-white differences and the judged degree of left-hemisphere involvement in the task, suggesting that black-white IQ discrepancies may be partially explained by differences in hemisphericity.     

The relationship between students' levels of school achievement,their preferences for future enrolment and their images of universities

A survey of 2000 final year students in secondary schools in Western Australia indicates that, although moderately performing students are unlikely to gain entry to university, the majority have a strong preference to attend university rather than vocational training (TAFE). Their actual institutional preferences are highly correlated with their self-perceived, level of academic achievement and their decisions on institutional preferences strongly influence their overall image of individual universities, across a number of dimensions. The research suggests that university marketing might benefit from a more thorough consideration of aspects of the marketing exercise, particularly in relation to the effectiveness of printed promotional material and whether it might more usefully target parents of prospective students.
