An analysis of contemporary motivation theories reveals implications for gifted and talented students. The expectancy-value framework, intrinsic-extrinsic motivation theories, goal orientations, self-efficacy and other self-perceptions, and attribution theory are described and discussed with respect to implications for the psychology and education of gifted and talented students. Illustrative e...
Introduction. What is the conception of talented students about university and academic and social life? Does this conception change before and after entering the university? How these changes occur and in which direction? Are these changes important? Do the talented students have any solution for academic life problems? Method. In a qualitative study 20 medical talented students were selected...
Talented students underachieve for many reasons and in many different circumstances. Unfortunately, there is no panacea for how to reverse underachievement in students whose talents are demonstrated in diverse ways. High-potential students with special needs are likely to experience underachievement as efforts to address their needs may focus more on remediation of difficulties and less on deve...
In this research project we empirically investigate career dynamics in the labour market for workers with highly specific talents. If firms cannot observe worker talent before employment, theory predicts that they will hire an inefficiently low amount of new workers and rehire too many experienced workers. We find strong support for this hypothesis in a uniquely detailed database on careers of ...
one of the main concerns of teachers in modern learner-centered approaches is whether published teaching materials can meet the needs of students at a particular leaning situation or the teachers ought to prepare their own materials. this dilemma gets worse when the teaching situation includes a textbook prescribed by an authority such as the ministry of education. in such cases, the teacher ha...
Chemical vapor deposition was employed to synthesize carbon nanotubes with Ni-loaded MCM-41 and MCM-48 as catalysts and acetylene as precursor at 750°C. Mesoporous Ni MCM-41 and Ni MCM-48 molecular sieves were synthesized by a hydrothermal method and were characterized by XRD and N2 adsorption isotherm. The catalytically synthesized carbon materials were characterized with Raman spectroscopy, N...
We report calculated oxygen reduction reaction energy pathways on multi-metal-atom structures that have previously been shown to be thermodynamically favorable. We predict that such sites have the ability to spontaneously cleave the O2 bond and then will proceed to over-bind reaction intermediates. In particular, the *OH bound state has lower energy than the final 2 H2O state at positive potent...
