Although exploratory (inquiry-based, discovery, problem-based) learning environments have been effective for certain categories of learners and instructional situations, they could also be very cognitively demanding, especially for novice learners. Such forms of instruction may generate a heavy working memory load caused by intensive unguided…

Evidence-based approaches to the design of the next generation of interactive distance education need to take into account established multimedia learning principles. Cognitive load theory is a theory that has significantly contributed to the development of such principles. It has applied our knowledge of major features and processing limitations…

Patterns of language are usually perceived, learned and used as meaningful chunks that are processed as a whole, resulting in a reduced learning burden and increased fluency. The ability to comprehend and produce lexical chunks or groups of words which are commonly found together is an important part of language acquisition. This paper…

Traditional assessment methods are not always suitable for diagnosing learners' knowledge structures at different levels of their expertise. This paper describes an alternative schema-based rapid assessment technique and its application in the area of arithmetic word problem solving. The technique is based on an assessment of the extent to which…

To tailor instruction to levels of learner proficiency in a domain in adaptive learning environments, rapid on-line methods of assessing learner knowledge and skills are required. Cognitive studies indicate that major factors in expert performance are organised structures in the person's knowledge base. Measuring different levels of acquisition of…
