The double‐dialectic and lifelong learning

This paper was provoked by Ted Bailey’s article, ‘Analogy, dialectics and lifelong learning’ which appeared in the March–April 2003 edition of this journal. Dr. Bailey argued that students can be enabled to learn the key concepts of the subjects they are studying through the dialectical operation of analogy which makes new knowledge accessible by comparing it to familiar experience. It is the aim of this paper to show that dialectics extend far beyond this particular application, and that indeed they may be said to underpin the very concept of lifelong learning itself. The paper begins by examining the concepts of the dialectic and the double‐dialectic, relating these to the writings of Giambattista Vico. The dialectical interplay of Nature and History is seen to be the foundation of human knowledge. This unitary view is then contrasted with specialism in the categorization of knowledge. The implications for lifelong education are considered, and illustrated through an example of a curriculum project.     

The Relationship Between Approaches to Learning and Reflection Upon Practice

This study examined the association between students' approaches to learning and stages of reflective thinking. The revised version of the Study Process Questionnaire was used to measure deep and surface approaches to learning and the Reflection Questionnaire was used to distinguish four stages of reflective and nonreflective thinking. Both questionnaires were completed by 402 undergraduates from all years of study from a health science faculty in a university in Hong Kong. Confirmatory factor analysis was used to test possible associations. The results showed that only the habitual action scale correlated significantly to surface approach to learning. Understanding, reflection and critical reflection correlated with deep approach but had no correlation to surface approach. Understanding, reflection and critical reflection correspond to the use of a deep approach with increasing levels of meaningful personal assimilation. These findings provide evidence of close association between approaches to learning and stages of reflection upon practice. The results also provide evidence for the convergent validity of both questionnaires.     

THE CONCURRENT VALIDITY OF STANDARDIZED ACHIEVEMENT TESTS BY CONTENT AREA USING TEACHERS' RATINGS AS CRITERIA

To assess the concurrent validity of standardized achievement tests using teachers' ratings (and rankings) of pupils' academic achievement as criteria, 42 teachers evaluated each of their students (n = 1,032) in each of five major curricular areas prior to the administration of a battery of standardized achievement tests. The teachers were directed to rate each student's proficiency disregarding attendance, attitude, deportment, and so on. Within-class correlation coefficients were computed to eliminate rater leniency bias. The standardized achievement tests were found to have substantial concurrent validity in reading, math, language arts, science, and social studies. The normalized teacher ranks yielded significantly higher validity coefficients than did the ratings, although the magnitude of the difference was small. The concurrent validity coefficients for language arts, reading, and math were significantly higher than those in science and social studies.     

FURTHER RESULTS ON THE STANDARD ERRORS OF ESTIMATE ASSOCIATED WITH ITEM-EXAMINEE SAMPLING PROCEDURES

Defining one observation as the score received by one examinee on one item, the results of this investigation suggest that, for a given test length, item-examinee sampling procedures having the same number of observation have, for all practical purposes, the same standard error in estimating μ but different standard errors in estimating σ. Additionally, the variance of the item difficulty indices (proportion answering the item correctly) was found to be a significant factor in accounting for differences in standard errors of estimating μ between normative distributions differing primarily in degree of skewness.     

To Control or Not to Control: The question of whether experimental designs are appropriate for evaluating teaching innovations in higher education

It is becoming increasingly common for academics to engage in research into their own teaching, usually by introducing some form of innovation into one of their courses. When doing so, they are often inclined by disciplinary tradition, or urged by senior colleagues, to use experimental designs in order that any observed outcomes can be attributed to the innovation itself. This article points out the problems with experimental designs for naturalistic studies of innovative teaching in higher education. A genuine control is impossible. Practical difficulties in separating groups often result in contamination of designs. Educational issues are complex with many variables involved. Therefore, experimental designs with limited numbers of cells result in over-simplification because they deal with only a few of the relevant factors. Particular types of innovation are not precisely reproducible so generalisation can be misleading. As an alternative, triangulation across multi-method evaluations from several sources is recommended, with the aim of establishing evidence beyond reasonable doubt. Comparison and synthesis across related projects appears to be a promising way to derive recommendations for ways to formulate important aspects of innovations.     

Three-dimensional kinematics of the lower limbs during forward ice hockey skating

The objectives of the study were to describe lower limb kinematics in three dimensions during the forward skating stride in hockey players and to contrast skating techniques between low- and high-calibre skaters. Participant motions were recorded with four synchronized digital video cameras while wearing reflective marker triads on the thighs, shanks, and skates. Participants skated on a specialized treadmill with a polyethylene slat bed at a self-selected speed for 1 min. Each participant completed three 1-min skating trials separated by 5 min of rest. Joint and limb segment angles were calculated within the local (anatomical) and global reference planes. Similar gross movement patterns and stride rates were observed; however, high-calibre participants showed a greater range and rate of joint motion in both the sagittal and frontal planes, contributing to greater stride length for high-calibre players. Furthermore, consequent postural differences led to greater lateral excursion during the power stroke in high-calibre skaters. In conclusion, specific kinematic differences in both joint and limb segment angle movement patterns were observed between low- and high-calibre skaters.     

Exploring Satisfying Experiences in Museums

This article presents results from an ongoing research project that investigates the experiences visitors find satisfying in museums. Using a list constructed from interviews with visitors and surveys, data were obtained from visitors in nine Smithsonian museums. Analysis of the results showed that experiences can be classified into four categories: Object experiences, Cognitive experiences, Introspective experiences, and Social experiences. The article points out that the type of most satisfying experience differs according to the characteristics of museums, exhibitions, and visitors. It also proposes an interpretation for these data, and suggests some possible applications.
