Evaluating the prediction of maximal heart rate in children and adolescents

In this study, we compared measured maximal heart rate (HRmax) to two different HRmax prediction equations [22 - age and 208 - 0.7(age)] in 52 children ages 7-17 years. We determined the relationship of chronological age, maturational age, and resting HR to measured HRmax and assessed seated resting HR and HRmax during a graded exercise test. Maturational age was calculated as the maturity offset in years from the estimated age at peak height velocity. Measured HRmax was 201 +/- 10 bpm, whereas predicted HRmax ranged from 199 to 208 bpm. Measured HRmax and the predicted value from the 208 - 0.7(age) prediction were similar but lower (p < .05) than the 220 - age prediction. Absolute differences between measured and predicted HRmax were 8 +/- 5 and 10 +/- 8 bpm for the 208 - 0.7 (age) and 220 - age equations, respectively, and were greater than zero (p < .05). Regression equations using resting HR and maturity offset or chronological age significantly predicted HRmax, although the R2 < .30 and the standard error of estimation (8.2-8.5) limits the accuracy. The 208 - 0.7(age) equation can closely predict mean HRmax in children, but individual variation is still apparent.     

Twelve-Month-Old Infants Respond to Speech About Absent Inaccessible Objects

This article investigated the interplay of 12-month-old infants’ perception of affordances for locomotion and their ability to respond to the mention of hidden objects. In Experiment I, a toy was hidden in an ottoman that was placed on a cabinet out of infants’ reach. Infants were more likely to look at, point to or approach the ottoman when there were stairs leading to it than when there were none. The stairs did not help infants respond by highlighting the target corner of the room (Experiment II) or by boosting their engagement with the study events (Experiment III). This suggests that infants’ perception of the accessibility of the hiding location influences their ability to respond to speech about absent things.     

Exploring the Promises and Perils of Integrated STEM Through Disciplinary Practices and Epistemologies

Growing interest in integrated science, technology, engineering, and mathematics (iSTEM) education has been promoted as one way to increase innovation capacity, support future employment, and enhance learning outcomes in K-12 education throughout the USA. Existing efforts to construct iSTEM curricula have largely focused on finding points of integration among commonly shared disciplinary practices, but these efforts have not explicitly accounted for the distinct epistemologies of the disciplines. In this study, we critically examined the concept of iSTEM by conducting a thematic analysis of K-12 STEM learning standards documents to identify cross-cutting themes among the practices of the various disciplines. We then analyzed these themes using disciplinary epistemologies in order to highlight some promises and perils of an integrated approach to STEM education. We identified eight cross-cutting themes: communicating, investigating, modeling, using tools, working with data, making sense of problems or phenomena, solving problems, and evaluating ideas or solutions. Through our analysis of practices and epistemologies, we discuss the promises of iSTEM, including fewer learning standards, enhanced epistemic fluency, increased diversity and inclusion in STEM, and opportunities to challenge settled and siloed disciplinary knowledge. We also discuss potential perils, which consist of conflation and/or exclusion of various STEM practices and epistemologies. We urge continued examination of iSTEM with an eye toward the epistemic implications.

     

Ability of test measures to predict competitive performance in elite swimmers

The purpose of this study was to quantify the relationship between changes in test measures and changes in competition performance for individual elite swimmers. The 24 male and 16 female swimmers, who were monitored for 3.6 years (s = 2.5), raced in a major competition at the end of each 6-month season (3.6 competitions, s = 2.2). A 7 x 200-m incremental swimming step-test and anthropometry were conducted in up to four training phases each season. Correlations of changes in step-test and anthropometry measures between training phases and seasons with changes in competition performance between seasons were derived with repeated-measures mixed-modelling and linear regression. Changes in competition performance were best tracked by changes in test measures between taper phases. The best single predictor of competition performance was skinfolds for females (r = -0.53). The best predictor from the step-test was stroke rate at a blood lactate concentration of 4 mmol x l(-1) (females: r = 0.46; males: r = 0.41); inclusion of the second-best step-test predictor in a multiple linear regression improved the correlations (females: r = 0.52 with speed in the seventh step included; males: r = 0.58 with peak lactate concentration included). In conclusion, a combination of fitness and technique factors is important for competitive performance. The step-test is a useful adjunct in a swimmer's training preparation for tracking large changes in performance.

Implementing co-teaching with paraprofessionals to provide pre-Kindergarten students with special rights access to dual language

The purpose of this study was to examine how paraprofessionals and other service providers participate in co-teaching with a certified special education pre-Kindergarten teacher during dual language (DL) instruction. The study took place in two DL special education preschool classrooms located in an urban public school district in the southwestern US. The district enlisted paraprofessionals as lead Spanish instructors when the lead teacher was not bilingual in Spanish and English to implement the DL programme effectively. Participants were one special education teacher, two paraprofessionals and one teaching artist, who participated in a year-long professional development programme to employ drama strategies to develop children's Spanish and English literacy skills and promote inclusion. Findings indicated that the participants utilised multiple co-teaching models to collaborate and meet the needs of their students during English and Spanish instruction. Through co-teaching, all educators had opportunities to take lead and supporting roles in instruction.     

The atmosphere vibrated with triumphant joy

Abstract

This article critiques the Indian material culture located in present-day Pakistan pertaining to the inaugural Australian cricket tour to colonial India in 1935/36. The historical voice of the Indians is evident in the images and it is over the shoulders of the hosts of the tour that new perspectives emerge. It is culturally inappropriate to assume and evaluate how the locals felt about the visit of the Australian cricketers and the raison d’être of the tour. However, archives located in Pakistan provide a deeply subjective perspective. Goodwill and amicability reverberate through the photographs challenging conventional scholarship, which argues that Australian-Indian cricket is based on acrimony. The article concludes that despite the obvious and significant differences between the competing teams the tour experience minimized the racial divide between the Australian and the Indian cricketers.
