Educating to Build Bridges

In March 2012, 30 faculty and 49 students from all over the world met in El Calafate, Argentina, during two intense weeks. It was the second Latin American School for Education, Cognitive, and Neural Sciences (LASchool), sponsored by the James S. McDonnell Foundation. The LA School seeks to critically examine research findings potentially relevant to the development, design, and implementation of effective educational practices, and to foster a new generation of researchers able to operate at the interface between education and science. Here we introduce a special issue which brings together theory, experiments, and educational interventions which emerged from ideas presented and discussed during the 2012 LASchool.     

Research and Transfer: A Teaching Project

This paper reports on a project that grew out of observations and conversations undertaken by two faculty members at LaGuardia Community College/CUNY interested in exploring the connection between research skills and transfer knowledge. Stern and Macheski posited that if students were able to connect research acquisition skills to the transfer application process, each skill would enhance the other. The outcomes from this small cohort, while not conclusive, lead the authors to be optimistic that their approach improves both understanding of authentic research and its connection to personal goals. National conversations in recent years about the changing role of community colleges inform this inquiry.     

Young,talented and injured: Injury perceptions,experiences and consequences in adolescent elite athletes

Even though injury is common in elite sports, there is still a lack of knowledge of young athletes’ injury perception both during and after injury. The aim of this mixed-method study was, therefore, to explore, in-depth, data on injury consequences and adolescent elite athletes’ perceptions and experience of injury. Three hundred and forty adolescent elite athletes (age range 15–19), from 16 different sports, were bi-weekly monitored over 52 weeks using a valid questionnaire. Twenty athletes from the same cohort were interviewed in focus groups about injury experience and perceptions. The results show that the average bi-weekly prevalence of injury was 38.7% (95% CI 37.3–40.1), with 30.0% (n?=?102) of the athletes injured for more than half of all reporting times. An overarching theme from the focus groups highlighted the risk among young athletes of a loss of identity while injured. The findings support several suggestions that may improve the rehabilitation process and enhance rehabilitation outcomes: (a) provide clear pathways to the medical team, (b) recognize the identity loss, (c) involve the injured athletes with the rest of the teammates and (d) educate athletes about how to interpret pain signals. Future research should explore and evaluate the effectiveness and generalization of such interventions.     

Resilience Among Children Exposed to Domestic Violence: The Role of Risk and Protective Factors

Individual and family characteristics that predict resilience among children exposed to domestic violence (DV) were examined. Mother–child dyads ( n  =   190) were assessed when the children were 2, 3, and 4 years of age. DV-exposed children were 3.7 times more likely than nonexposed children to develop internalizing or externalizing problems. However, 54% of DV-exposed children maintained positive adaptation and were characterized by easy temperament (odds ratio [OR] = .39, d  = .52) and nondepressed mothers (OR = 1.14, d  = .07), as compared to their nonresilient counterparts. Chronic DV was associated with maternal depression, difficult child temperament, and internalizing or externalizing symptoms. Results underscore heterogeneous outcomes among DV-exposed children and the influence of individual and family characteristics on children's adaptation.     

Time of day and short-duration high-intensity exercise influences on coagulation and fibrinolysis

Exercise has been demonstrated to have considerable effects upon haemostasis, with activation dependent upon the duration and intensity of the exercise bout. In addition, markers of coagulation and fibrinolysis have been shown to possess circadian rhythms, peaking within the morning (0600–1200?h). Therefore, the time of day in which exercise is performed may influence the activation of the coagulation and fibrinolytic systems. This study aimed to examine coagulation and fibrinolytic responses to short-duration high-intensity exercise when completed at different times of the day. Fifteen male cyclists (VO_2max: 60.3?±?8.1?ml?kg^?1?min^?1) completed a 4-km cycling time trial (TT) on five separate occasions at 0830, 1130, 1430, 1730 and 2030. Venous blood samples were obtained pre- and immediately post-exercise, and analysed for tissue factor (TF), tissue factor pathway inhibitor (TFPI), thrombin–anti-thrombin complexes (TAT) and D-Dimer. Exercise significantly increased plasma concentrations of TF (p?p?p?p?p?=?.004) and TFPI (p?=?.031), with 0830 greater than 1730 (p .001), while 1730 was less than 2030?h (p?=?.008), respectively. There was no significant effect of time of day for TAT (p?=?.364) and D-Dimer (p?=?.228). Power output, TT time and heart rate were not significantly different between TTs (p?>?.05); however, percentage VO_2max was greater at 1730 when compared to 2030 (p?=?.04). Due to a time-of-day effect present within TF, peaking at 0830, caution should be applied when prescribing short-duration high-intensity exercise bout within the morning in populations predisposed to hypercoagulability.     

Teachers’ perceptions of student evaluations of teaching

Evaluation of teaching in higher education has drawn much attention due to the need for greater accountability and improvement in student learning. Our review of literature on Student Evaluation of Teaching (SET) surveys suggests that considerable controversy and criticism have surrounded its use, fairness, and validity. Yet, many universities in Hong Kong are depending primarily on student feedback in SET surveys to provide evidence for their improvement of teaching and learning, and for their decisions made on teachers' pay-rise and tenure. If universities are to continue to use SET surveys as the main source of mechanism for measuring teaching effectiveness, teachers will have to understand and be aware of its purposes. But how much do we know about teachers' perceptions of teaching and learning and, consequently, their opinions of using SET surveys as the primary standardized evaluation mechanism of teaching for promotion and tenure and for teaching effectiveness?     

The Application of Moral Judgments to Other Cultures: Relativism and Universality

This study examined how moral judgments are applied to events in other cultures. It was hypothesized that subjects make both universal and relativistic judgments, contingent on the types of beliefs held in the culture to which the moral judgments were applied. It was furthermore expected that subjects would be both relativists and universalists at all ages. 72 subjects (aged 11–9, 15–10, and 21–3 years) were asked to apply moral judgments which they had made about a familiar context to 2 types of cultures, 1 where different informational beliefs were held and 1 where different moral beliefs were held. The results confirmed the hypotheses. Most subjects, at all ages, contextualized their moral judgments when they applied them to cultures with different informational beliefs but made nonrelativistic judgments with respect to cultures with opposing moral beliefs. Furthermore, subjects justified their relativistic judgments on informational grounds and their nonrelativistic judgments on moral grounds. These findings demonstrated that nonrelativistic and relativistic thinking coexist throughout a wide age range and underscored the need to distinguish between moral and nonmoral relativism when studying developmental patterns in the moral domain.     

Combinations of Epoch Durations and Cut-Points to Estimate Sedentary Time and Physical Activity Among Adolescents

The purpose of the current study was to investigate how combinations of different epoch durations and cut-points affect the estimations of sedentary time and physical activity in adolescents. Accelerometer data from 101 adolescents were derived and 30 combinations were used to estimate sedentary time, light, moderate, vigorous, and combined moderate-to-vigorous physical activity. Data were analyzed with repeated measurement analyses of variance. Large differences of sedentary time and times of different physical activity intensities were observed between 1 s and longer epoch durations using virtually all cut-points. Generally, sedentary time, moderate physical activity, vigorous physical activity, and combined moderate-to-vigorous physical activity progressively decreased, whereas light physical activity increased with longer epoch durations. The extreme differences between cut-points were large and increased with longer epoch durations for sedentary time and for all physical activity intensities except for vigorous physical activity per epoch duration. Caution is required when cross-comparing studies using different epoch durations and cut-points. To accurately register adolescents’ spontaneous intermittent physical activity behavior, short epoch durations are recommended.
