Disseminating the Positively Aging® Teaching Materials: Results of a Controlled Trial

ABSTRACT

This study tested the effectiveness of 2 dissemination methods for the Positively Aging® teaching materials. In San Antonio, Texas, 4 middle schools participated in a 3-year controlled trial of dissemination via distance electronic support alone (control) compared to distance electronic support plus in-school support from study staff (intervention). Web site and classroom utilization of lessons were tracked. The results demonstrated that in-school staff support was necessary to disseminate these materials. Potential dissemination barriers included competition for instructional time with other curricula, teacher variability in teacher computer use, teacher and student turnover, and the effects of mandatory testing on the educational process.     

Understanding communication among deaf students who sign and speak: a trivial pursuit?

Classroom communication between deaf students was modeled using a question-and-answer game. Participants consisted of student pairs that relied on spoken language, pairs that relied on American Sign Language (ASL), and mixed pairs in which one student used spoken language and one signed. Although the task encouraged students to request clarification of messages they did not understand, such requests were rare, and did not vary across groups. Face-to-face communication was relatively poor in all groups. Students in the ASL group understood questions more readily than students who relied on oral communication. Although comprehension was low for all groups, those using oral communication provided more correct free responses, although the numbers were low; no significant differences existed for multiple-choice responses. Results are discussed in terms of the possibility that many deaf students have developed lower criteria for comprehension, and related challenges for classroom communication access.     

Comparison of anthropometry to dual energy X-ray absorptiometry: a new prediction equation for women

The purpose of this study was to assess the accuracy of three recommended anthropometric equations for women and then develop an updated prediction equation using dual energy x-ray absorptiometry (DXA). The percentage of body fat (%BF) by anthropometry was significantly correlated (r = .896-.929; p < .01) with DXA, but each equation underestimated %BF (3.2-5.6 %BF; p < .01). The following DXA criterion (DC) equation was created: %BF= -6.40665 + 0.41946(S3SF) - 0.00126(S3SF)2 + 0.12515(hip) + 0.06473 (age); (S3SF = sum of triceps, suprailiac, thigh; hip = circumference in cm; age = years). The predicted residual sum of squares (PRESS) R2 was high (0.86), and the PRESS standard error of estimate (SEE) was low (2.5 %BF) for our sample of 150 women. The DC equation was further crosschecked on a separate sample of women (n = 25) and again showed excellent agreement. The DC equation appears to be a more accurate estimation of %BF in women.     

Baseline Hypothalamic–Pituitary–Adrenal Axis and Parasympathetic Nervous System Activity Interact to Predict Executive Functions in Low‐Income Children

We examined interactions between baseline hypothalamic–pituitary–adrenal (HPA) axis and parasympathetic nervous system (PNS) activity in relation to executive functions (EF) in a sample (n = 1,005) of children in low wealth, nonurban communities at age 48 months. Salivary cortisol and respiratory sinus arrhythmia (RSA) represented baseline HPA axis and PNS activity, respectively. The interaction between RSA and cortisol predicted EF such that children with either lower RSA and lower cortisol, or higher RSA and higher cortisol had higher EF scores. These findings suggest a potential compensatory relation in which the PNS and HPA axis counterbalance each other to support cognition.     

First-Year Students’ Time Use in College: A Latent Profile Analysis

Students’ time expenditures influence their learning and development. This study used latent profile analysis to identify a taxonomy of how first-year students spend their time using a large multi-institution sample. We identified four time usage patterns by first-year students titled Balanced, Involved, Partiers, and Parents. Sex, expected major field, on-campus residency, age, Greek-life membership, and standardized test scores were predictive of students’ time use patterns. Holding a range of student and institutional factors constant, members of the involved group, on average, reported higher levels of engagement than the Balanced group, while Partiers reported lower levels of engagement. Implications for policy and practice are discussed.     

“The Changers and the Changed”: Preparing Early Childhood Teachers to Work With Lesbian,Gay, Bisexual,and Transgender Families

The Census Bureau estimates that up to 14 million children under the age of 18 are being raised by lesbian, gay, bisexual, or transgender (LGBT) families. Just as heterosexual families require child care to enable work and want high-quality early childhood education to enhance their children's development, LGBT families experience the same needs and desires for their children. However, similar to other educational institutions, the early childhood field has either held negative beliefs regarding diverse family structures or ignored the unique needs of LGBT families. As part of an effort to address teachers' understandings of equity, faculty at a southeastern university sponsored a course designed to prepare early childhood teacher education students to offer welcoming, inclusive learning environments for LGBT families and their young children. The purpose of this article is to examine the learning process and transformation of students in this course. Findings from quantitative and qualitative data are presented, as is a discussion on how courses on family equity can and should be incorporated into teacher education programs.     

Sprachförderkompetenz pädagogischer Fachkräfte

This paper introduces the basics of a (psycho)linguistically-oriented model of language-training competences of educators in pre-school and elementary education. It specifies competence criteria for language intervention based on psycholinguistic research. Ultimately, these criteria will be useful for grounding the additional training of educators and for certifying competences in early language intervention.     

The value of neurosurgical and intraoperative magnetic resonance imaging and diffusion tensor imaging tractography in clinically integrated neuroanatomy modules: A cross‐sectional study

Neuroanatomy is considered to be one of the most difficult anatomical subjects for students. To provide motivation and improve learning outcomes in this area, clinical cases and neurosurgical images from diffusion tensor imaging (DTI) tractographies produced using an intraoperative magnetic resonance imaging apparatus (MRI/DTI) were presented and discussed during integrated second‐year neuroanatomy, neuroradiology, and neurosurgery lectures over the 2008–2011 period. Anonymous questionnaires, evaluated according to the Likert scale, demonstrated that students appreciated this teaching procedure. Academic performance (examination grades for neuroanatomy) of the students who attended all integrated lectures of neuroanatomy, was slightly though significantly higher compared to that of students who attended these lectures only occasionally or not at all (P=0.04). Significantly better results were obtained during the national progress test (focusing on morphology) by students who attended the MRI/DTI‐assisted lectures, compared to those who did so only in part or not at all, compared to the average student participating in the national test. These results were obtained by students attending the second, third and, in particular, the fourth year (P≤0.0001) courses during the three academic years mentioned earlier. This integrated neuroanatomy model can positively direct students in the direction of their future professional careers without any extra expense to the university. In conclusion, interactive learning tools, such as lectures integrated with intraoperative MRI/DTI images, motivate students to study and enhance their neuroanatomy education.
