Language and reading impairments are associated with increased prevalence of non-right-handedness

Handedness has been studied for association with language-related disorders because of its link with language hemispheric dominance. No clear pattern has emerged, possibly because of small samples, publication bias, and heterogeneous criteria across studies. Non-right-handedness (NRH) frequency was assessed in N = 2503 cases with reading and/or language impairment and N = 4316 sex-matched controls identified from 10 distinct cohorts (age range 6–19 years old; European ethnicity) using a priori set criteria. A meta-analysis (N_cases = 1994) showed elevated NRH % in individuals with language/reading impairment compared with controls (OR = 1.21, CI = 1.06–1.39, p = .01). The association between reading/language impairments and NRH could result from shared pathways underlying brain lateralization, handedness, and cognitive functions.     

Science education — I: The spirit of science

In these two essays we explore the questions: what are the essential features of a workable context for science education? What are the givens, the “of courses,” the “fundamental dispositions” toward science and toward education necessary — or at least sufficient — to provide a fertile ground upon which a functional approach to science education can be established? In the present essay it is argued first that science education must reflect that science is a way of thinking — in fact, more comprehensively, a way of being; and second, and that the fundamentally antiauthoritarian spirit of science must be reconciled with education, with its built-in tendency to be authoritarian.

Cognitive and social help giving in online teaching: an exploratory study

While literature suggests that college students may be less reluctant to seek help in online rather than traditional courses, little is known about how online instructors give help in ways that lead to increased student help seeking and academic success. In this study, we used theories and research on learning assistance and scaffolding, teacher immediacy, social presence, and academic help seeking to explore through a cross-case study design how three online instructors differed in their use of cognitive and social supports and how those differences related to student perceptions of support, help seeking, and performance. Primary data sources included all course postings by the instructors, interviews with the instructors, observational field notes on course discussions, student interviews, and final student grades. Archived course documents and student discussion postings were secondary data sources. Data analysis revealed that while all instructors provided cognitive and social support, they varied in their level of questioning, use of direct instruction, support for task structuring, and attention to group dynamics. This variation in teaching presence related to differences across the courses in student perceptions of support, student help seeking in course discussions, and final course grades. Implications for online teaching and suggestions for further research are offered.

The Project Ownership Survey: Measuring Differences in Scientific Inquiry Experiences

A growing body of research documents the positive outcomes of research experiences for undergraduates, including increased persistence in science. Study of undergraduate lab learning experiences has demonstrated that the design of the experience influences the extent to which students report ownership of the project and that project ownership is one of the psychosocial factors involved in student retention in the sciences. To date, methods for measuring project ownership have not been suitable for the collection of larger data sets. The current study aims to rectify this by developing, presenting, and evaluating a new instrument for measuring project ownership. Eighteen scaled items were generated based on prior research and theory related to project ownership and combined with 30 items shown to measure respondents’ emotions about an experience, resulting in the Project Ownership survey (POS). The POS was analyzed to determine its dimensionality, reliability, and validity. The POS had a coefficient alpha of 0.92 and thus has high internal consistency. Known-groups validity was analyzed through the ability of the instrument to differentiate between students who studied in traditional versus research-based laboratory courses. The POS scales as differentiated between the groups and findings paralleled previous results in relation to the characteristics of project ownership.     

Centering the Educational and Social Significance of HBCUs: A Focus on the Educational Journeys and Thoughts of African American Scholars

In this article we provide a brief history of historically Black colleges and universities (HBCUs) as a part of the sociopolitical context framing this special issue. The aim of this issue is to situate HBCUs as centers of leadership, change, and influence as well as repositories of Black education and the Black American experience through their legacy of intellectual, cultural, and communal engagement. We argue that the lived experiences of HBCU graduates provide a deeper understanding of their positionalities in the landscape of U.S. American higher education outcomes.
