Can 'ears-on' help hands-on science learning for girls and boys?

The primary objective of the research was to establish whether the use of the newly developed audiopilot (a personalized auditory commentary system) facilitates both hands-on exploration and the understanding of scientific principles in a science centre. Twenty-four ten year-old children used the AudioPilot while they interacted with a set of pendulum experiments. A control group of 28 children from the same classes experienced the same experiments but without the Audio-Pilot. Videos were made of all the children and their behaviours were later coded. They completed a questionnaire about pendulums before and after going to the science centre. A gender effect emerged. The audio-pilot greatly facilitated the girls' hands-on activity and improved their questionnaire scores, which was highly statistically significant. This suggests that auditory commentaries are a good way of communicating difficult scientific concepts, especially to girls. Further research is needed to confirm whether this finding can be generalized over different schools.     

Predicting reading level in grades 1 to 6 from listening level and decoding level: Testing theory relevant to the simple view of reading

The relationships among pronunciation level (decoding), verbal level (listening), and accuracy level (reading) were investigated in grades 1 to 6, and for students who are in the advanced phase of decoding. The data collected were used to investigate the validity of the simple view of reading and the causal model of reading achievement which holds that pronunciation level (P_L) and verbal level (V_L) are the proximal causes of accuracy level (A_L). A total of 135 students in grades 1-6 were given measures of nonword decoding, real word decoding, listening, and reading. All of the reliable variation in an indicant of the level of reading ability, A_L, could be predicted from an indicant of the level of ability to decode real words, P_L, and an indicant of listening level, V_L. Furthermore, the strong relationship between pronunciation level, P_L, and accuracy level, A_L, did not evaporate for the students who had mastered basic decoding skills, as measured by nonword decoding tests. The correlations between pronunciation level, P_L, and accuracy level, A_L, were high even for students in grades 5 and 6, most of whom probably had progressed beyond the alphabetic phase (phonological recoding). Correlational support was found for the simple view of reading and the causal model which holds that A_L is equal to the square root of the product of V_L and P_L. The above theory and supporting data were interpreted as suggesting that the level of reading accuracy, A_L, of students can be improved the most throughout grades 1 to 6 by emphasizing instruction that will improve pronunciation level, or decoding, even for children who have progressed beyond the beginning to read phase which involves learning the alphabetic principal, or phonological recoding.     

Managing reading and related literacy difficulties: University students’ perspectives

This study explored the experiences of university students who identified as always having had reading difficulties. Thirty-three participants, all from one Australian university, were surveyed and 10 were also interviewed. Findings revealed that many shared academic challenges related to studying, along with a belief that their difficulties were not well understood by staff or peers. While participants disclosed many similar personal struggles related to completing their studies, positive attributes such as determination and time management strategies were frequently mentioned as instrumental in allowing them to reach university. Experiences were more variable regarding awareness of, access to, and satisfaction with university-based support and academic adjustments. To facilitate optimal inclusive educational practices, this study supports the need for greater awareness among staff about challenges faced by these university students along with a more individualised and targeted approach to providing them with academic supports and accommodations.     

Neuromuscular variables affecting the magnitude of force loss after eccentric exercise

The aim of this study was to examine neuromuscular variables contributing to differences in force loss after participants were exposed to the same relative bout of eccentric exercise. Thirty-six males performed 50 maximal eccentric contractions of the elbow flexors and were stratified into high responders (n = 10) and low responders (n = 10) based on force loss 36 h after exercise. Maximal voluntary isometric contractions (MVCs) and electromyography (EMG) were measured at baseline and 36 h after exercise. During eccentric exercise, mean peak torque, mean end-range torque from the final 25% of each trial and total angular impulse were computed over 25 contractions in each of two bouts. The slope of the change in these values for each 25 eccentric contractions was calculated for each participant using linear regression. At baseline, MVC was not different between groups (low responders: 97.0 +/- 9.6 N x m; high responders: 82.7 +/- 6.4 N x m; P = 0.08). High responders demonstrated a 68% (range 62-78%) reduction in MVC and low responders a 39% (29-48%) reduction after exercise. Peak torque, end-range torque and total angular impulse were 13%, 40% and 33% higher, respectively, in the low than in the high responders (peak torque: P = 0.0002; end-range torque: P < 0.0001; total angular impulse: P < 0.001). The rate of decline in peak torque slope was greater in high than in low responders (P = 0.044). In conclusion, lower peak torque, end-range torque and total angular impulse during eccentric contractions and a greater peak torque slope may identify high responders to eccentric exercise.     

Emergency Response Systems and the Creeping Legibility of People and Places

Over the last 35 years, centralized universal-number (in the United States, 9-1-1) systems have come to be the preferred means of emergency-response dispatching. The creation of these systems has motivated the development of information systems that render the landscape, to those with the right access, increasingly legible. This has been to the benefit of those receiving emergency services, but also to the benefit of police and commercial interests, who have used the improved infrastructure as bases for the creation of geodemographic and other profiling systems. More recently, the creation of wireless telephony has motivated the creation of a further surveillance infrastructure built on and integrated into that landscape. One consequence has been the commercialization of the systems in ways that permit the incorporation of more intimate and detailed data into preexisting systems. Public concern with locational surveillance systems has focused on privacy. However, “privacy” may be an inadequate frame through which to understand these issues and to fashion appropriate responses.     

Black doctoral student research participants: A mixed-method systematic literature review

In this study, we use a mixed-method systematic literature review of articles that include African American counselor education doctoral student participants in the research. From this corpus of inquiry, we provide an opportunity for counselor education researchers to lead the way with inclusive scholarship and the use of strengths-based frameworks. We examine how to conceptualize research particularly for African American doctoral student participants and offer suggestions on how to write the discussion and implication sections in a way to promote innovation and excellence.
