Ndebele culture of Zimbabwe's views of giftedness

This study explored Ndebele culture of Zimbabwe's views of giftedness. Using questionnaire narratives, data were collected from thirty Zimbabwean teachers and lecturers of Ndebele cultural background. The study established that Ndebele culture views giftedness as an unusually outstanding ability blessed in an individual from birth, which manifests in extraordinary performances and expertise including creativity and inspirational power. The hallmarks of Ndebele culture's views of giftedness are achieving exceptionally outstanding success, creativity, ability to solve problems and inspirational power. Indigenous views warrant attention since contemporary psychology now recognizes multiple views of giftedness. The study therefore recommends considering the implications of indigenous views in planning and implementing broad‐based culturally sensitive gifted programs in Zimbabwe.     

Enhancing the status of peer observation through the scholarship of teaching and learning

In this Reflection on Practice I argue the case for using the principles of scholarship of teaching and learning (SoTL) to serve as a framework for evaluating and designing peer observation programmes in higher education contexts. I suggest that for peer observation to be an activity worthy of SoTL, it should be systematic, collaborative, rigorous, peer reviewed, and focused on learning about teaching to improve teaching. Using a set of criteria to critique a current peer observation programme I account for its strengths and weaknesses and suggest a way forward for elevating the status of peer observation.     

Residual force enhancement due to active muscle lengthening allows similar reductions in neuromuscular activation during position- and force-control tasks

BackgroundResidual torque enhancement (rTE) is the increase in torque observed during the isometric steady state following active muscle lengthening when compared with a fixed-end isometric contraction at the same muscle length and level of neuromuscular activation. In the rTE state, owing to an elevated contribution of passive force to total force production, less active force is required, and there is a subsequent reduction in activation. In vivo studies of rTE reporting an activation reduction are often performed using a dynamometer, where participants contract against a rigid restraint, resisting a torque motor. rTE has yet to be investigated during a position task, which involves the displacement of an inertial load with positional control.MethodsA total of 12 participants (6 males, 6 females; age = 22.8 ± 1.1 years, height = 174.7 ± 8.6 cm, mass = 82.1 ± 37.7 kg; mean ± SD) completed torque- and position-matching tasks at 60% maximum voluntary contraction for a fixed-end isometric contraction and an isometric contraction following active lengthening of the ankle dorsiflexors.ResultsThere were no significant differences in activation between torque- and position-matching tasks (p = 0.743), with ∼27% activation reduction following active lengthening for both task types (p < 0.001).ConclusionThese results indicate that rTE is a feature of voluntary, position-controlled contractions. These findings support and extend previous findings of isometric torque-control conditions to position-controlled contractions that represent different tasks of daily living.
