An Investigation of Cognitive Processes Engaged in by Recreational Computer Game Players: Implications for Skills of the Future

Abstract This exploratory study investigated the influence of two recreational computer games on children’s subsequent performance on computer-based instructional tasks. Children were assigned to three groups: two were invited to play their respective recreational computer games, and the third acted as a control group. All three groups then worked on a common set of educational tasks from environmental education software. The three groups’ performances on a set of educational tasks were compared using quantitative analysis for speed and correct solutions, and then qualitatively for the cognitive manoeuvres engaged in to accomplish the tasks. The findings suggest that playing recreational computer games may influence children’s performance on subsequent computer-based educational tasks. However, the extent of this influence depended on how closely the recreational computer game types matched the design of the tasks in the educational software. The cognitive manoeuvres used by game players also depended on the types of games played during the learning phase. Linear cause-and-effect games tended to encourage means–end analysis strategy, whereas adventure games encouraged inferential and proactive thinking. Though the findings of this study are encouraging, further studies need to be undertaken to replicate the results.

Validation of the diagnostic tool for assessing Tertiary students’ readiness for online learning

Increasing numbers of educational institutions are adopting an online approach to teaching and learning; however, little regard has been given to the prerequisite personal and technical qualities required for academic achievement and satisfaction within this environment. In recognition of this, researchers have been exploring the design, development and testing of diagnostic tools to assess student readiness for online learning. This study builds on previous work by the authors to further validate their diagnostic tool for assessing Tertiary students’ readiness for online learning (TSROL) which has four subscales: ‘Technical skills’, ‘Computer self‐efficacy’, ‘Learner preferences’ and ‘Attitudes towards computers’. Factor and reliability analyses revealed that Technical skills and Computer self‐efficacy possessed good reliability and validity, and ‘Attitudes towards computers’ fair reliability and validity. However, ‘Learner preferences’ required revision as it possessed poor reliability and validity. Analysing the demographic data revealed that older students had lower Technical Skills and computer self‐efficacy than younger students. The TSROL can be improved by adopting a more multidimensional interpretation of the Learning preferences and Attitudes towards computers subscales.

Cognitive load and mental rotation: structuring orthographic projection for learning and problem solving

Cognitive load theory was used to generate a series of three experiments to investigate the effects of various worked example formats on learning orthographic projection. Experiments 1 and 2 investigated the benefits of presenting problems, conventional worked examples incorporating the final 2-D and 3-D representations only, and modified worked examples with several intermediate stages of rotation between the 2-D and 3-D representations. Modified worked examples proved superior to conventional worked examples without intermediate stages while conventional worked examples were, in turn, superior to problems. Experiment 3 investigated the consequences of varying the number and location of intermediate stages in the rotation trajectory and found three stages to be superior to one. A single intermediate stage was superior when nearer the 2-D than the 3-D end of the trajectory. It was concluded that (a) orthographic projection is learned best using worked examples with several intermediate stages and that (b) a linear relation between angle of rotation and problem difficulty did not hold for orthographic projection material. Cognitive load theory could be used to suggest the ideal location of the intermediate stages.

Technoliteracy and Learning: An Analysis of the Quality of Knowledge in Electronic Representations of Understanding

Abstract Recent educational research from a socio-cognitive perspective has validated students’ collaborative engagement with new technologies and heightened understanding of influential factors shaping the effectiveness of peer interactions, learning contexts and computer interfaces for enhancing learning. This paper focuses on an analysis of the complexity of knowledge in student-designed, electronically created texts for what they might reveal about learning with technology. It reports on a study with 17-year-old female students whose collaborative learning process in subject English was mediated by the creation of electronic concept maps and Web files to represent their developing understanding. To analyse these electronic texts, evaluative criteria templates were developed from the Structure of Observed Learning Outcomes (SOLO) taxonomy, integrating levels of understanding with the distinctive characteristics of multimodal text production. Findings indicated not just the incremental acquisition of conceptual understanding equated with cognitive change but that the level of understanding might also be positively influenced by the students’ length of exposure to computer-mediated learning practices. As well, the criteria templates have emerged as useful evaluative tools for classroom assessment or further research when analysis of the level of complexity of student-created, electronic artefacts is required.

Career Aspirations of Older Workers: An Australian Study.

Global challenges associated with the ageing workforce include lower levels of education and negative attitudes of older workers towards learning and covert age discrimination in the workplace. This report discusses initial findings from a survey of older workers employed in regional areas in Australia. The older workers surveyed were predominantly blue collar with low levels of formal education. Contrary to the stereotypical views, there were few attitude differences between older (>40 years) and younger workers (d40 years). However, gender, education level and job type had a greater impact on attitudes in the older workers when compared to their younger colleagues.

Sequential development of algebra knowledge : a cognitive analysis

Learning to operate algebraically is a complex process that is dependent upon extending arithmetic knowledge to the more complex concepts of algebra. Current research has shown a gap between arithmetic and algebraic knowledge and suggests a pre-algebraic level as a step between the two knowledge types. This paper examines arithmetic and algebraic knowledge from a cognitive perspective in an effort to determine what constitutes a pre-algebraic level of understanding. Results of a longitudinal study designed to investigate students’ readiness for algebra are presented. Thirty-three students in Grades 7, 8, and 9 participated. A model for the transition from arithmetic to pre-algebra to algebra is proposed and students’ understanding of relevant knowledge is discussed.

Cognitive Processes and Strategies Employed by Children To Learn Spatial Representations.

Children often have difficulties in learning spatial representations. This study investigated the effect of four different instructional formats on learning outcomes and strategies used when dealing with spatial tasks such as assembly procedures. It was hypothesised that instructional material that imposed least extraneous cognitive load would facilitate enhanced learning. Forty secondary students were presented with four types of instruction; orthographic drawing, isometric drawing, physical model and, isometric and physical model together. The findings provide evidence to suggest that working from physical models caused least extraneous cognitive load compared to the isometric and orthographic groups. The model group took less time, had more correctly completed models, required fewer extra looks, spent less time studying the instruction and made fewer errors. Problem decomposition, forward working and attending to information in the foreground of the graphical representation strategies were analysed.

Developing a diagnostic tool for assessing tertiary students' readiness for online learning

The increasing investment in developing high quality systems for online learning has focused more on technology with little regard for learners’ readiness to learn through such systems. One of the reasons for this was an assumption that most students have the necessary capacity (technical and attitudinal) to deal with online learning. This assumption is increasingly being challenged in recent years. This paper explores the difficulties experienced by online learners and develops a diagnostic survey instrument to ascertain learner readiness to participate in online learning environments. Through confirmatory factor analysis, four factors were identified: Technical skills, Learner self-efficacy, Learning preference and Learner attitude. This paper reports on the design and development of the survey instrument.

Cognitive Load and Assembly Tasks: effect of instructional formats on learning assembly procedures

The study investigated the effect on learning of four different instructional formats used to teach assembly procedures. Cognitive load and spatial information processing theories were used to generate the instructional material. The first group received a physical model to study, the second an isometric drawing, the third an isometric drawing plus a model and the fourth an orthographic drawing. Forty secondary school students were presented with the four different instructional formats and subsequently tested on an assembly task. The findings indicated that there may be evidence to argue that the model format which only required encoding of an already constructed three dimensional representation, caused less extraneous cognitive load compared to the isometric and the orthographic formats. No significant difference was found between the model and the isometric-plus-model formats on all measures because 80% of the students in the isometric-plus-model format chose to use the model format only. The model format also did not differ significantly from other groups in total time taken to complete the assembly, in number of correctly assembled pieces and in time spent on studying the tasks. However, the model group had significantly more correctly completed models and required fewer extra looks than the other groups.

Transitional Employment Aspirations for Bridging Retirement: Implications for Training and Development.

Purpose: The aim of this study was to identify the transitional employment aspirations and training and development needs of older and younger workers at risk of early retirement due to limited education and/or employment in blue collar occupations. Design/ Methodology/ Approach: A computer based methodology was used to evaluate the demographic effects of gender, education level and occupation group on aspirations pertaining to transitional employment and training and development in a sample of over 1000 Local Government employees. Findings: Older blue collar, secondary school educated and younger workers were less interested in transitional employment than older workers with higher levels of education or from white collar backgrounds. The early retirement risk factors of blue collar work and secondary school education had a more limited effect on perceived training and development needs for older workers. However for younger workers, these risk factors provided the impetus to undertake training to move into less physically demanding or more challenging roles as their careers progressed. Practical Implications: Via the identification of education level and occupation types groups’ transitional employment aspirations and perceptions of preparatory training and development within younger and older cohorts, long term strategies to develop and retain staff may be formulated. Originality/ Value: Past studies of transitional employment have rarely included younger workers or older workers at risk of early retirement. Preparatory training and development for transitional employment roles has not been considered in the literature.
