The purpose of this study is to investigate the integration of a cognitive apprenticeship model in a Web-based course. The subject of this study is an educational technology course for pre-service P-12 teacher education students. Specifically, this study presents student reports of how cognitive apprenticeship methods impacted student learning processes of (a) technology skills and (b) technolo...

Cognitive load theory states that improper cognitive loads may negatively affect learning. By identifying students’ working memory capacity (WMC), personalized scaffolding techniques can be used, either by teachers or adaptive systems to offer students individual recommendations of learning activities based on their individual cognitive load. WMC has been identified traditionally by dedicated t...

Invention activities are Productive Failure activities in which students attempt (and often fail) to invent methods that capture deep properties of a construct before being taught expert solutions. The current study evaluates the effect of scaffolding on the invention processes and outcomes, given that students are not expected to succeed in their inquiry and that all students receive subsequen...

Assembly of certain classes of bacterial and animal viruses requires the transient presence of molecules known as scaffolding proteins, which are essential for the assembly of the precursor procapsid. To assemble a procapsid of the proper size, each viral coat subunit must adopt the correct quasiequivalent conformation from several possible choices, depending upon the T number of the capsid. In...

This study examined and organised comments made by teachers participating in a variety of learning communities in order to sort a list of recommendations for future development of webbased teachers’ training taking into consideration possible trajectories of web powerful technological innovations. The comments are organised under a theoretical framework of professional scaffolding.

It is well known that introductory physics students often have alternative conceptions that are inconsistent with established physical principles and concepts. Invoking alternative conceptions in the quantitative problem-solving process can derail the entire process. In order to help students solve quantitative problems involving strong alternative conceptions correctly, appropriate scaffolding...

Two studies documented and evaluated parental scaffolding of 3and 4-year-olds' spatial communication. In Study 1, children gave directions to parents about locations of objects. Three-year-olds gave ambiguous directions more often than 4-year-olds, and parents used directive prompts more often with 3-year-olds than 4-year-olds, Study 2 compared the effectiveness of parental prompts in a control...

Is it possible to enhance neural and cognitive function with cognitive training techniques? Can we delay age-related decline in cognitive function with interventions and stave off Alzheimer's disease? Does an aged brain really have the capacity to change in response to stimulation? In the present paper, we consider the neuroplasticity of the aging brain, that is, the brain's ability to increase...
