Student Perceptions of Cognitive Efficiency: Implications for Instruction

Bobby Hoffman
2013 International Journal of Educational Psychology  
This study used a phenomenological approach with content analysis to create a model of how students perceive cognitive efficiency (CE), which is generally described as increases in the rate, amount, or  ...  Analysis of results revealed that student perceptions of CE predominantly focused on malleable aspects of self-regulated and reflective cognition, aligning with many descriptions of expert teaching.  ...  During knowledge acquisition, the relative effectiveness of instruction materials, the modality of delivery or pedagogical style can influence how learners regulate mental effort, and subsequently achieve  ...

CEO���s commitment bias, ownership concentration, and innovation decision: Behavioral management of CEO���s discretion

Hamza Fadhila, Azouzi Mohamed Ali, Jarboui Anis, Steve Cook
2014 Cogent Economics & Finance  
In particular, we found that the application of a persuasion mechanism does not have a real impact on the alignment of the manager's attitude and behavior in key tasks, such as the innovation decision.  ...  Abstract: This paper deals with approving the effect of both a governance system and individual cognitive and emotional features in the financial analysis of a firms' innovation decision.  ...  On the other hand, with the absence of a commitment link between the manager and risk investment decision, their effort has no influence on the CEO's risk investment behavior.  ...

Cognitive load theory and music instruction

Paul Owens, John Sweller
2008 Educational Psychology  
It asks learners to introspect on the perceived intensity of mental effort expended during a task 119 .  ...  Any activated frame of reference (schema) exerts an unconscious influence on what is perceived.  ...  To extend the investigation of dual modality, these experiments maintained identical conditions and groups of participants across two independent sets of materials.  ...
