Impact of HIPPY on home learning environments of Latino families

This study investigated effects of Home Instruction of Parents of Preschool Youngsters (HIPPY), a paraprofessional home visiting program, on parents and children. The program site served low-income, Spanish-speaking families. On average, mothers were 31 years old (SD = 4.78) and children were 3 or 4 years old (M = 3.92, SD = .92). Participants (n = 54) had more parenting self-efficacy and more enriched home environments than families on a waiting list (n = 54). In a regression on home environment, participation in the intervention was a stronger predictor than maternal education, depression, and stress. A third-grade follow-up of children in the program showed significantly higher math achievement when compared to low-income Latino third graders in the same school district. These findings appear to validate the HIPPY model, which suggests that parents gain confidence as their children's teachers through their experiences in the program. HIPPY successfully addresses the need for culturally sensitive programming aimed at improving educational achievement among minority children.     

Cognitive functioning in children with and without Attention-deficit/Hyperactivity Disorder with and without comorbid learning disabilities

This study attempted to determine whether children with the combined subtype of attention-deficit/hyperactivity disorder (ADHD) have impairments in cognitive functioning and motor skills. The specific effect of the comorbidity of learning disabilities (LD) was also investigated. A battery of cognitive tests was administered to 26 children with a clinical diagnosis of ADHD-combined subtype (ADHD/C), to 24 children with ADHD/C with a comorbid diagnosis of LD (ADHD/C+LD), and to 102 participants without disabilities, all between ages 7 and 10. The testing battery consisted of tasks assessing memory, visuospatial and verbal abilities, and fine motor skills. In general, the test results of children with ADHD/C were poorer than those of the control group but better than the results of children with a combined ADHD/C+LD diagnosis (with the exception of motor skills). The predictive accuracy of the testing battery tasks in children with ADHD/C and ADHD/C+LD was examined. The results of a standard procedure of discriminant function analyses revealed that the measures correctly classified 73.6% of the children.     

An Exploratory Study of the Effects of Time Compressed Animated Delivery Multimedia Technology on Student Learning in Reproductive Physiology

Two experiments examined the effects of a multimedia technology referred to as “Time Compressed Animated Delivery” (TCAD), on student learning in a junior-level reproductive physiology course. In experiment 1, participating students received one of two presentations of the same instructional material: TCAD and a lecture captured on video. At the completion of each presentation a test was administered and group mean test scores computed and compared. The results were statistically significant (df = 362, t = 10.623, p < 0.05), favoring the TCAD treatment group. The effect size estimate was 1.14. In experiment 2, student learning from three groups were compared on the same reproductive physiology unit used in experiment 1: (1) TCAD, (2) TCAD without the 3-D component, and (3) video-lecture. After removal of three poor functioning items, a one-way analysis of variance was computed. The results were statistically significant (df = 2, F = 2.351, p < 0.10). Results of post hoc comparisons showed that differences in mean test scores between the TCAD and control groups were statistically significant (p < 0.05). The effect size estimate was 0.25. These findings provide preliminary evidence for use of TCAD.     

Color vision in the giant panda (Ailuropoda melanoleuca)

Hue discrimination abilities of giant pandas were tested, controlling for brightness. Subjects were 2 adult giant pandas (1 male and 1 female). A simultaneous discrimination procedure without correction was used. In five tasks, white, black, and five saturations each of green, blue, and red served as positive stimuli that were paired with one or two comparison stimuli consisting of 16 saturations of gray. To demonstrate discrimination, the subjects were required to choose the positive stimulus in 16 of 20 trials (80% correct) for three consecutive sessions. Both subjects reached criterion for green and red. The female subject also reached criterion for blue. The male was not tested for blue. This study is a systematic replication of Bacon and Burghardt’s (1976) color discrimination experiment on black bears. The results suggest that color vision in the giant panda is comparable to that of black bears and other carnivores that are not strictly nocturnal.     

Comparing overexcitabilities of gifted and non-gifted school children in Hong Kong: does culture make a difference?

Overexcitabilities (OEs) are ways that an individual experiences the world and can be understood as channels of information flow. The current study examined the profile of OEs among a group of Hong Kong children. Participants included 229 non-gifted and 217 gifted children. OEs were measured using the Overexcitability Questionnaire II. Results indicated that there were differences between the gifted and the non-gifted groups in all OE subscales. Gender differences were also identified. Females, in both gifted and non-gifted groups, have a significantly higher score in Emotional OE when compared to males. In addition, gifted females also scored significantly higher than their male counterparts in Sensual OE. Results of this study were compared to a group of American children (based on C.L. Tieso's work on overexcitabilities in 2007). The implications and limitations of this study are presented.     

Imperatives and challenges in integrating teaching and research

This paper explores why it is important for universities to integrate research and teaching at the present time and considers how it can be achieved. Political, institutional and disciplinary factors affect the relationship, whether the aim is to integrate teaching with research or to integrate research with teaching. So the article explores factors that facilitate and factors that discourage integration. By way of providing an example of implementation, imperatives and challenges in developing this relationship at a large research‐intensive Australian university are outlined. Finally, the paper draws some general implications from this discussion to suggest where moves by disciplinary communities to integrate research and teaching might be heading.     

Neural Correlates of High Performance in Foreign Language Vocabulary Learning

Learning vocabulary in a foreign language is a laborious task which people perform with varying levels of success. Here, we investigated the neural underpinning of high performance on this task. In a within-subjects paradigm, participants learned 92 vocabulary items under two multimodal conditions: one condition paired novel words with iconic gestures and the other with meaningless gestures. Memory performance was assessed through single-word translation tests. High performers consistently learned more items than low performers, regardless of the training condition, the time, and the difficulty of the task. Brain activity measured upon word recognition using functional magnetic resonance imaging was parametrically related to the behavioral data. High performance correlated with activity in the left angular gyrus (BA 39) and in the right extrastriate cortex (BA 19). These cortical areas mediate integration of information across different modalities as well as memory processes. Thus, high performance in vocabulary learning seems to depend on individual capacities to integrate and associate a word's semantics with sensorial stimuli. This may have important implications for education.     

Rethinking Electronic Portfolios to Promote Sustainability among Teachers

Electronic portfolios (eportfolios) can increase reflection, develop content and pedagogy skills and facilitate communication between teachers and administrators. However, they have limitations. Despite resources that teacher institutions devote to eportfolios, research suggests that most implementations are of limited duration. In a climate where sustained professional development and lifelong learning are necessary to remain competitive, organizations should reevaluate how eportfolios are implemented to sustain use and maintain skills deemed important by teaching organizations. Using principles of change theory, this article identifies several eportfolio challenges and how they may be improved through principles of personal learning environments. Implementation procedures and limitations are also provided.
