Examining the effects of a highly rated science curriculum unit on diverse students: Results from a planning grant

This article reports on the results of a planning grant studying the effects of a highly rated curriculum unit on a diverse student population. The treatment was introduced to 1500 eighth grade students in five middle schools selected for their ethnic, linguistic, and socioeconomic diversity. Students were given pre‐, post‐, and delayed posttests on a Conservation of Matter Assessment and measures of motivation and engagement. This quasi‐experiment found statistically significant posttest results for achievement, basic learning engagement, and goal orientation. Analyses of disaggregated data showed that subgroups of students in the treatment condition outscored their comparison group peers (n = 1500) in achievement in all cases, except for students currently enrolled in ESOL. Analysis of video data of a diverse group of four students as the unit was enacted suggests that students entered a learning environment that permitted them to function in different, but consistent ways over time; that is, the frequency of students' manipulation of objects showed a different pattern of engagement for each of the four students compared with patterns of verbal responses such as the use of scientific terms. The results of this planning grant paved the way for a large study of the scale‐up of highly rated curriculum units. © 2005 Wiley Periodicals, Inc. J Res Sci Teach 42: 912–946, 2005     

The language of science and the high school student: The recognition of concept definitions: A comparison between hindi speaking students in India and english speaking students in Australia

Sixteen concept words (mass, length, area, volume, solid, liquid, gas, element, compound, mixture, electron, proton, neutron, atom, molecule, and ion) associated with the theme, the nature of matter were described as simple text book definitions after examination of classroom notes and school texts of the last three decades. Sixteen multiple-choice items all of the same form were constructed for each of the concept definitions. The English version of the sixteen item test was given to 1635 high school students in Tasmania (where the language of instruction and the home language is English) and the Hindi version of the test was given to 826 students from the Bhopal/Barwani region of India where the medium of instruction is Hindi. The English and Hindi speaking data are compared from the point of view of development, performance for individual items, and overall performance at grade 10. A number of linguistic hypotheses are examined and reported upon. Although the overall score at grade 10 was identical (10.8/16) for both groups there are differences in development overall and for individual items which are of interest. Overall, the science specificity of the Hindi words does not appear to confer any clearly defined advantage or disadvantage though again there are some interesting individual anomolies.     

Childhood emotional invalidation and adult psychological distress: the mediating role of emotional inhibition

OBJECTIVE: To evaluate a model in which chronic emotional inhibition mediates the relationship between a history of childhood emotional invalidation or abuse and adult psychological distress. METHOD: One hundred and twenty-seven participants completed a series of self-report questionnaires, and a subset of this group (n=88) completed an additional measure of current avoidant coping in response to a laboratory stressor. Structural equation modeling was used to evaluate and compare a full and partial mediational model. RESULTS: Findings strongly supported a model in which a history of childhood emotional invalidation (i.e., psychological abuse and parental punishment, minimization, and distress in response to negative emotion) was associated with chronic emotional inhibition in adulthood (i.e., ambivalence over emotional expression, thought suppression, and avoidant stress responses). In turn, emotional inhibition significantly predicted psychological distress, including depression and anxiety symptoms. CONCLUSION: This study found support for a model in which the relation between recollected negative emotion socialization in childhood and adult psychological distress was fully mediated by a style of inhibiting emotional experience and expression. Although it is likely that childhood emotional inhibition is functional (e.g., reduces parental distress and rejection), results suggest that chronic emotional inhibition may have long-term negative consequences for the inhibitor.     

Short-term professional learning that focuses on beliefs and practice: Improvements in preschool teachers’ ongoing literacy practice

An intervention study was conducted with preschool teachers to address their beliefs and practice in the area of language and literacy. A total of 27 preschool teachers, each from different early childcare centers, participated in three 1-day professional learning sessions over the course of 9 months. Learning sessions focused on three different language and literacy topics. Study participants completed a pre- and post-session questionnaire and were observed in the classroom before and after each session. Significant differences were observed in both their beliefs and practice after the intervention. Specifically, preschool teachers’ beliefs were related to their practice in two areas: oral language and vocabulary; and book reading. Based on the data, a focus on beliefs and practice in future short-term PL or workshop models may support successful outcomes in teaching practice.     

Varsity athletes have lower 2D:4D ratios than other university students

The second to fourth digit ratio (2D:4D) is a sexually dimorphic trait with lower finger ratios considered more masculine. These digit ratios are believed to reflect the prenatal hormonal environment with higher exposure to androgens in utero leading to more masculine digit ratios. The 2D:4D ratio has been negatively correlated with many factors, including aggression, physical fitness, and athleticism. We compared 2D:4D finger ratios of (1) male and female varsity athletes (n = 99) versus male and female student non-athletes (n = 122), and (2) males (n = 104) versus females (n = 117). Our results confirmed that both male (mean ± s(x) : 0.97 ± 0.004) and female (0.98 ± 0.005) varsity athletes had significantly lower ratios than their non-varsity peers (males: 0.99 ± 0.004; females: 1.00 ± 0.006), and that male athletes had significantly lower 2D:4D ratios than female athletes. Overall, males had significantly lower 2D:4D ratios than females (0.98 ± 0.003 vs. 0.99 ± 0.004). A smaller 2D:4D ratio appears to be consistent with participation in varsity sports among both males and females.     

Grants for Processing: A Case Study in Grant Writing and Project Management at the Brooklyn College Archives

This article describes the process of finding the right grant to meet the needs of a processing project, the application and peer review process, and the experience of administering the grant received from the National Historical Publications and Records Commission (NHPRC). The project is the processing of the YWCA of Brooklyn Collection, housed at Brooklyn College. The records have significant research potential in a variety of fields including women’s studies and sociology. While generally smooth, the administration of the grant has required the replacement of a departing Project Archivist, and the use of interns for some conservation work.
