Chemistry problem solving instruction: a comparison of three computer-based formats for learning from hierarchical network problem representations

Within the cognitive load theory framework, we designed and compared three alternative instructional solution formats that can be derived from a common static hierarchical network representation depicting problem structure. The interactive-solution format permitted students to search in self-controlled manner for solution steps, static-solution format displayed all solutions steps, and no-solution format did not have solution steps. When we matched instructional time across the formats, in relation to the complex molarity problems rather than the dilution problems, differential transfer performance existed between the static-solution or no-solution formats and the interactive-solution format, but not between the static-solution format and no-solution format. The manner in which learners interact with the static-solution and no-solution formats depends on their level of expertise in the chemistry domain. With considerable learner expertise, provision of solution steps may be redundant incurring extraneous cognitive load. Absence of the solution steps may not have left sufficient cognitive capacity for germane cognitive load as some beginning learners lacked the prior knowledge to deduce the solution steps. Searching for solution steps presumably incurred extraneous cognitive load which interfered with learning and hence, in the interactive-solution format, it outweighed the benefit of engaging in self-regulated interaction with the content. Hence, cognitive load theory is a promising tool to predict the mental load associated with learning from the three alternative computer-based instructional formats.     

Using CBL to improve cognitive load and reduce feedback redundancy in Accounting distance learning

This study explored the value of providing Introductory Accounting distance education students with feedback via a computer‐based learning (CBL) package modelled on teacher dialogue. CBL provided tightly focussed feedback without increasing the materials’ complexity ('element interactivity'), and without redundant feedback, while ensuring the learners engaged with the materials at an optimal ('germane') mental processing level. The CBL feedback provided verification and elaboration at key points. The CBL was used to complement written learning materials. The students using CBL performed significantly better than the total group. The students found the CBL materials useful, but ranked the written materials higher than CBL. Both student preferences and learning results indicated the value of CBL feedback.     

Exploring Multidimensional Approaches to the Efficiency of Instructional Conditions

Research on Cognitive Load Theory has shownthat measures of cognitive load can revealimportant information about the cognitiveconsequences of instructional conditions thatis not necessarily reflected by traditionalperformance-based measures. Although, theindividual measures of cognitive load can beconsidered important to determine the power ofdifferent instructional conditions, ameaningful interpretation of a certain level ofcognitive load can only be given in the contextof its associated performance level, and viceversa. This was recognized by Paas and VanMerriënboer (1993) who developed a2-dimensional computational approach to combinemeasures of test performance with measures ofthe associated mental effort in order tocompare the `mental efficiency' ofinstructional conditions. In this approach,high task performance associated with loweffort is termed high instructional efficiency,whereas low task performance with high effortis termed low instructional efficiency.Here we explore the utility of employingmulti-dimensional approaches, in particular two2-dimensional efficiency measures and a new3-dimensional approach, which combines themeasures of learning effort, test effort andtest performance. Each of these approaches withtheir associated insights and analyses may beuseful for instructional researchers, e.g. asdiagnostic instruments to identify differentaspects of efficient or inefficientinstructional conditions and can be implementedin a broad range of learning environments,including electronic environments, possiblyenabling more effective learning-task selection.     

Encouraging IT students to get serious about assignment writing: evaluation of a Web-based initiative

Traditionally, students attending university have received support for their assignment writing within a face-to-face framework. Academic writing support delivered via the Internet needs to be rendered in very subject-specific terms for the resource to be perceived as valuable. This paper reports on a project involving writing support staff and a computer science subject leader to develop and evaluate a Web-based academic skills tutorial. The tutorial sought to provide online learning support for interpreting an information technology (IT) assignment topic, extracting information from sources, and integrating the material into a report with the support of online lexical tools. The evaluation sought to determine whether the students found the resource helpful, if improvements were still required, and what implications there were for integrating the resource with subject teaching. Students perceived most value in those sections of the resource that provided them with examples and models, and least in those that required them to engage in interactive activity.     

Inferring Student Learning Behaviour from Website Interactions: A Usage Analysis

Web-based learning environments are now used extensively as integral components of course delivery in tertiary education. To provide an effective learning environment, it is important that educators understand how these environments are used by their students. In conventional teaching environments educators are able to obtain feedback on student learning experiences in face-to-face interactions with their students, enabling continual evaluation of their teaching programs. However, when students work in electronic environments, this informal monitoring is not possible; educators must look for other ways to attain this information. Capturing and recording student interactions with a website provides a rich source of information from data that is gathered unobtrusively. The aim of this study was firstly to explore what information can be gained from analysing student interactions with Web-based learning environments and secondly to determine the value of this process in providing information about student learning behaviours and learning outcomes. This study has provided critical information to educators about the learning behaviour of their students, informing future enhancements and developments to a courseware website and the teaching program it supports.     

A motivational perspective on the relation between mental effort and performance: Optimizing learner involvement in instruction

Motivation can be identified as a dimension that determines learning success and causes the high dropout rate among online learners, especially in complex e-learning environments. It is argued that these learning environments represensent a new challenge to cognitive load researchers to investigate the motivational effects of instructional conditions and help instructional designers to predict which instructional configurations will maximize learning and transfer. Consistent with the efficiency perspective introduced by Paas and Van Merriënboer (1993), an alternative motivational perspective of the relation between mental effort and performance is presented. We propose a procedure to compute and visualize the differential effects of instructional conditions on learner motivation, and illustrate this procedure on the basis of an existing data set. Theoretical and practical implications of the motivational perspective are discussed.     

Transforming Learning Support: An Online Resource Centre for a Diverse Student Population

The diverse student population at large multi-campus universities requires English language and academic skills support which is targeted to their needs and easily accessible. The Online Student Resource Centre website, developed at Monash University, provides opportunities for students, no matter where they are, to make contact with staff and to access information, but more significantly offers a suite of stand-alone tutorials and downloadable resources, using NetObjects Fusion as the platform. These derive from some 100 print booklets covering academic writing, reading, listening, speaking, grammar and study skills/exam strategies. This paper outlines the process and philosophy of development of these tutorials, based on a constructivist framework, with guided and self-directed learning paths designed to accommodate a range of learning styles. Two tutorials are analysed to highlight some of the pedagogical challenges in translating print resources for the online environment. The paper concludes by reporting on a pilot evaluation of the two tutorials. Transformation d’un support d’enseignement: un centre de ressources en ligne pour une population
