The changes that have occurred in accepted approaches to teaching and learning in recent years have been underpinned by shifts in psychological and pedagogical theory, culminating in moves towards a constructivist view of learning. This paper looks at the consequences of these theoretical shifts for Computer Assisted Learning (CAL).
Moshman has identified three interpretations of constructivism: endogenous constructivism which emphasises learner exploration, exogenous constructivism which recognises the role of direct instruction, but with an emphasis on learners actively constructing their own knowledge representations and dialectical constructivism which emphasises the role of interaction between learners, their peers and teachers. This classification scheme provides a framework for looking at the various constructivist approaches to CAL.
For example, constructivist CAL materials that draw on the endogenous view include hypermedia environments, simulations and microworlds. Materials that draw on the exogenous view include learner controlled tutorials, cognitive tools and practice modules. Lastly, materials that draw on the dialectical view include Computer Supported Collaborative Learning (CSCL) tools and support (or scaffolding) tools.  相似文献

Tenth grade students studied the topic of ‘The growth curve of microorganisms’, which included a computer‐assisted learning (CAL) simulation episode. The CAL episode enabled students to simulate experiments which investigated the simultaneous impact of three independent variables upon the growth curve of microorganisms (temperature, nutrient concentration and the initial number of individuals from which to start a population growth). Two classes (n = 82 students) formed the experimental group and were instructed in a combination of classroom‐laboratory work with CAL. The control group included three classes (n = 99 students) who were taught the topic in the classroom‐laboratory work setting only. Five teachers taught the five classes, three periods weekly and the study lasted 4 weeks. The students’ previous knowledge in the topic to be learned and their academic achievement were assessed with pre‐ and post‐tests, respectively. The data for each lest were treated with a two‐way analysis of variance. The results showed that the two study groups did not differ in their previous knowledge and no significant differences were found by gender within and between the groups. The post‐test results on academic achievement indicated that students in the experimental group achieved significantly higher means scores than the control group. No significant gender differences on academic achievement were found within each group. The results affirm that: (a) computer simulations, in which three variables are manipulated simultaneously in one experiment, can be integrated as short episodes in the existing biology curricula; (b) high school students can perform computer simulations which require the skills of simultaneous manipulations of three variables in one experiment, problem solving and decision making; (c) girls and boys in the experimental group exhibited these skills at a similar academic level of achievement.  相似文献

This paper identifies key factors affecting conceptual gains from using a CAL package and their application to a practical laboratory class. Data was collected on over 120 first year students who studied a CAL package as an integral part of their course at two sites of a university. A variety of factors were analysed in order to identify which ones affected conceptual gains. These factors were students' biographical characteristics, design features of the CAL package and the way the CAL was integrated into the curriculum. The key factors that were identified as having an effect on conceptual gains were the students' prior academic attainment, their prior use of email, the WWW and CAL packages, and the way that the CAL package was integrated into the course. Those students, who were most successful in learning from the CAL and applying this learning, had higher academic attainment and had previously used the WWW, email and other CAL packages. They were also better at linking their study of the CAL package to other parts of the course.  相似文献

The Directed–Self Education programme (DSE) in the first year undergraduate course in veterinary anatomy seeks to support students in developing personal study and information technology skills. It also aims to move computer–assisted learning (CAL) towards offering tools for students to create a variety of computer–based materials of their own which subsequently can be repurposed by staff as teaching resources. This aspect addresses the issue that many British academics have little incentive to devote time to improving teaching through CAL methods, as innovation and excellence in teaching is not rewarded in career terms on par with excellence in research. The programme seeks to integrate a modest type of "problem–based learning" (PBL) methodology without demanding the total integration of pre–clinical with clinical teaching advocated by full–scale PBL. Since 1993 the outcomes of the programme have been that lectures in the first year veterinary anatomy course have been reduced by a third, with a slight change in the mean value of the final grades in the first year final examination in veterinary anatomy during 1994–5, as compared to the years 1991–3. Other benefits have included the rapid creation of a library of student–produced CAL which is recycled by staff into other forms of computer–based teaching. It has also led to involvement in the use of CAL by lecturers hitherto resistant to applying technology to teaching, and the vacation employment of current BVSc undergraduates from the programme in university and national projects producing CAL for medical teaching.  相似文献

Abstract

In September 1990 computer assisted learning (CAL) was introduced at the Larenstein International Agricultural College. At first, CAL was only used for remedial teaching. The use of CAL was extended in 1991 to some regular courses (statistics, economy), and some courseware has been developed for specific purposes.

Students like the use of CAL, especially in the regular courses. They appreciate the immediate feedback and the flexibility of the programmes. Teachers are also positive about this kind of instruction, because theses lessons are less tiring for them, and because it gives them more time to help students with serious problems.

It is hard to prove that exam results get better, but there are signs that CAL help to improve the quality of education. However, CAL is an educational instruments that keeps students alert, just because it is different.  相似文献

Computer‐assisted learning (CAL) is becoming ever more important as a method of teaching and facilitating learning in an increasingly overburdened higher education sector in the UK. A number of authors have made pleas for more evaluation and research in the area of CAL. This study set out to evaluate the attitudes to CAL amongst over 300 business and management undergraduates using a questionnaire survey. The survey revealed a positive disposition towards CAL irrespective of age, gender or educational background. In addition respondents were asked to compare the features of CAL with those of other more traditional methods of teaching and learning. Two factors were identified, labelled CAL ‘instructional’ features and CAL ‘tutorial’ features. The instructional features of CAL were rated more highly than its tutorial features. Respondents rated CAL as better than traditional methods in terms of its instructional features and about the same as traditional methods in terms of its tutorial features. Younger respondents rated the instructional features of CAL more highly than did the older respondents. The findings were discussed in terms of their implications for the use of CAL in an expanding system of mass higher education.  相似文献

Computer‐aided learning (CAL) is an integral part of many medical courses. The neuroscience course at Oxford University for medical students includes CAL course of neuroanatomy. CAL is particularly suited to this since neuroanatomy requires much detailed three‐dimensional visualization, which can be presented on screen. The CAL course was evaluated using the concept of approach to learning. The aims of university teaching are congruent with the deep approach—seeking meaning and relating new information to previous knowledge—rather than to the surface approach of concentrating on rote learning of detail. Seven cohorts of medical students (N = 869) filled in approach to learning scale and a questionnaire investigating their engagement with the CAL course. The students' scores on CAL‐course‐based neuroanatomy assessment and later university examinations were obtained. Although the students reported less use of the deep approach for the neuroanatomy CAL course than for the rest of their neuroanatomy course (mean = 24.99 vs. 31.49, P < 0.001), deep approach for CAL was positively correlated with neuroanatomy assessment performance (r = 0.12, P < 0.001). Time spent on the CAL course, enjoyment of it, the amount of CAL videos watched and quizzes completed were each significantly positively related to deep approach. The relationship between deep approach and enjoyment was particularly notable (25.5% shared variance). Reported relationships between deep approach and academic performance support the desirability of deep approach in university students. It is proposed that enjoyment of the course and the deep approach could be increased by incorporation of more clinical material which is what the students liked most.

There is growing interest by both educators and policymakers in helping underperforming students catch up using computer assisted learning (CAL). While CAL interventions have been shown to be effective internationally and elsewhere in China, these have been mostly offline CAL programs that are difficult and costly to implement. An online CAL (OCAL) may be able to bypass many of offline CAL's implementation problems and enhance the remedial tutoring experience. The objective of this paper is to examine the impact of an OCAL intervention on the academic and non-academic performance of students and to explore the mechanism behind OCAL's impact. According to the findings, OCAL improved overall English scores of students in the treatment group relative to the control group by 0.48 standard deviations. This impact is large when compared with offline CAL programs previously evaluated in rural China. We found that OCAL also led to a positive change in the attitudes of students towards English learning and student aspirations for their future education level. We found three possible explanations for OCAL's impact. We believe that online features that enhance the interest-oriented stimulation of the software is the main source of improvement among students. Cost-effectiveness analysis showed that the OCAL program is more cost-effective than traditional offline CAL, which is suitable for policymakers as it indicates high potential for OCAL program expansion.  相似文献

While the use of computer assisted learning (CAL) along with the techniques of fixed-format testing are fairly well established in the United States, they are only recently finding their way into general use in the United Kingdom. The authors review their progress in introducting CAL to the British social work education scene. Since 1983 they havce developed a number of programmes for teaching and testing mental health. They have applied these programmes under controlled conditions, investigating variouis aspects of CAL in respect of both student preference and performance. The results have been generally favourable to date and point the way for continued work.  相似文献

This review, which can be seen as a scoping review, highlights 92 empirical studies about the learning and instruction of reading Chinese as an additional language (CAL) published in English between 1976 and 2018. It first identifies and evaluates the trends of CAL reading research over the past four decades, including the developmental trajectory of the field, topics that are hot versus those not-so-hot, populations that are widely studied versus under studied, research methods adopted in the selected studies, and the most widely cited articles. Second, the review examines direct evidence that supports effective practices of CAL reading instruction and explores two tracks of studies: high-evidence versus low-evidence practices. This review concludes with thoughts on the future directions of CAL reading research inspired by trends in the areas of literacy, second language acquisition (SLA), and teaching Chinese as a second/foreign language (TSCL/TCFL). To be specific, there is a need for the field to pay equal attention to learning to read and reading to learn.  相似文献

Beginning in the spring of 1983, a series of in-service courses in computer-assisted learning (CAL) for post-primary schoolteachers was organized under the auspices of the Microelectronics Education Programme (Northern Ireland Region). The courses were presented on a workshop basis and provided the teachers with the opportunity to consider the use of CAL in their teaching. The teachers attending the courses were invited to complete questionnaires which were designed to assess (a) the current level of CAL practice in schools and (b) the effectiveness of the various types of support, including in-service training, available for teachers interested in developing CAL practice in their teaching. This paper reports on the findings arising from the questionnaires.  相似文献

Following an analysis of the stages in software production this paper argues that team production remains the only satisfactory method of providing high quality software but that the key to a higher quantity of reasonable quality computer-assisted learning production lies in the development of support technology adequate to permit individual teachers to develop software within their existing curriculum framework. Three promising approaches—software toolboxes, CAL program shells and software CAL analysts—are described.  相似文献

This paper reports an investigation of cognitive style, gender, attitude toward using computer‐assisted learning (CAL) and academic achievement among university students. A Group Embedded Figures Test was used to assess students’ cognitive style and a questionnaire was used for the evaluation of students’ attitude toward CAL. The results revealed that students have positive attitudes toward CAL but they were not prepared to rely entirely on CAL. A 2 x 2 ANOVA was used to investigate the effect of cognitive style and gender on the attitude toward CAL. The results revealed that male students preferred using CAL significantly more than females and field dependent students were more prepared to rely entirely on CAL than field independent students. On the other hand, there was a significant difference between males and females in their achievement scores in favour of the male group. But there was no difference between field dependence and field independence groups in their achievement. The results also revealed no significant relationship between students’ attitudes toward CAL and their achievement in these courses.  相似文献

We have developed a tool for the authoring of adaptive CAL courses, called "Dynamic Courseware Generator" (DCG). It generates an individual course according to the learner's goals and previous knowledge, and dynamically adapts the course according to the learner's success in acquiring knowledge. The DCG runs on a WWW server. The learner receives from this server an individualised course targeted to a specified goal. Afterwards, s/he is adaptively guided by the course through a space of teaching materials on the WWW. Unlike other CAL courses on the WWW, a course produced by the DCG is interactive, it tests the learner's knowledge and dynamically adapts to the student's progress. The authoring tool can be used also for collaborative authoring and learning.  相似文献

Action learning has evolved over a period of time when managerialism and performativity, which are aspects of neoliberalism, have become stronger and this explains, in part, the emergence of Critical Action Learning (CAL). Performativity, in particular, has increasingly become internalised by people at work. CAL seems to be limited to power relations within and between organisations and thus tends to ignore the dominant ideology of the day – neoliberalism. The paper asserts that action learning is antithetical to a neoliberal worldview and there are therefore practical implications for action learning practitioners.  相似文献

Anatomy is an essential subject of the medical curriculum. Despite its relevance, the curricular time and logistical resources devoted to teaching anatomy are in decline, favoring the introduction of new pedagogical approaches based on computer-assisted learning (CAL). This new pedagogical approach provides an insight into students' learning profiles and features, which are correlated with knowledge acquisition. The aim of this study was to understand how training with CAL platforms can influence medical students' anatomy performance. A total of 611 medical students attending Musculoskeletal Anatomy (MA) and Cardiovascular Anatomy (CA) courses were allocated to one of three groups (MA Group, CA Group, and MA + CA Group). An association between the performance in these anatomy courses and the number of CAL training sessions was detected. In the MA Group (r = 0.761, P < 0.001) and the MA + CA Group (r = 0.786, P < 0.001), a large positive correlation was observed between musculoskeletal anatomy performance and the number of CAL training sessions. Similarly, in the CA Group (r = 0.670, P < 0.001) and the MA + CA Group (r = 0.772, P < 0.001), a large positive correlation was observed between cardiovascular anatomy performance and the number of CAL training sessions. Multiple linear regression models were performed, considering either musculoskeletal or cardiovascular anatomy performance as the dependent variable. The results suggest that using CAL platforms to study has a positive dose-dependent effect on anatomy performance. Understanding students' individual features and academic background may contribute to the optimization of the learning process.  相似文献

This article addresses key topics of Chinese as an Additional Language (CAL) education and classroom pedagogical practices. It reports on a 3-year ethnographic study within Australian schools to discuss dialogic pedagogical practices and students’ aspirations. Based on Freire’s conceptualisation of conscientização and banking education, the purpose of this article is therefore to unpack a journey to voices, courage and hope of a cohort of socially, linguistically and economically disadvantaged students in Western Sydney, one of the most culturally diverse regions in the country. Their experiences, responses, dreams and understanding of CAL education in multicultural Australia were thus captured. Our data shows that critical CAL education might point to some avenues for the educational equity agenda. By arguing that emancipatory and critical practices could enhance students to achieve consciousness and collective self-transformation, we aim to make a contribution to the literature on CAL and languages education, which all too often isolates from broader issues in educational theory. The article also adds to the limited research that engages with CAL classroom data. Our critical approach to CAL education illuminates the intersections between language and social inclusion. Considering the worldwide growing upheaval and scepticism around CAL education, we call for writing inclusive languages education and related pedagogical practices into the social inclusion agenda in Australia and internationally, for the teaching and learning of all additional languages.  相似文献

Pigeons received variable-interval (VI) reinforcement for keypecking during randomized presentations of seven line-orientation stimuli forming a continuum ranging from horizontal (0 deg) to vertical (90 deg). Each line presentation lasted for 30 sec and was preceded and followed by 30-sec time-outs. After responding stabilized, only responding in the two extreme stimuli (0 and 90 deg) was reinforced. As discrimination training proceeded, strong behavioral contrast and dimensional contrast effects appeared. However, only marginal local effects (local contrast and local dimensional effects), exerted by one line-orientation component upon a second, appeared, indicating that behavioral and dimensional contrast may be independent of parallel local effects. An attempt was made to apply Blough’s (1975) quantitative model of operant generalization and discrimination to the present discrimination procedure. However, this model did not predict the generalization gradient shape that was experimentally obtained. This experiment also yielded two serendipitous findings: (1) Positive behavioral contrast appeared in an extinction-related stimulus (time-out) when other stimuli were switched from reinforcement to extinction (hitherto, positive behavioral contrast had been observed only in responding to a reinforcementrelated stimulus when other stimuli were switched from reinforcement to extinction), and (2) final responding was higher in the presence of an extinction stimulus that had always been an extinction stimulus than it was in the presence of other extinction stimuli that had previously been paired with VI reinforcement.  相似文献

In 1993 the Government expressed its concern that:'the traditional PhD is not well-matched to the needs of careers outside research in academia or an industrial research laboratory' (OST, 1993, p. 3).
This government concern appeared to encourage innovation in developing the doctorate to meet a wider range of career needs.
By contrast, in 1996, the Harris Committee Report recommended that standardisation of the forms and nomenclature of postgraduate courses, including research degree courses, 'could bring national coherence and hence clarity in an international marketplace' (Harris, 1996, p. 38).
In this article we have developed a national profile of research degree awards using data from individual universities. This profile allows us to explore empirically issues of variety and standardisation in research degrees and seek ways of reconciling the need for innovation with the need to protect coherence and clarity.  相似文献
