Effects of forced movements on learning: Findings from a choice reaction time task in rats

To investigate how motor sensation facilitates learning, we used a sensory–motor association task to determine whether the sensation induced by forced movements contributes to performance improvements in rats. The rats were trained to respond to a tactile stimulus (an air puff) by releasing a lever pressed by the stimulated (compatible condition) or nonstimulated (incompatible condition) forepaw. When error rates fell below 15%, the compatibility condition was changed (reversal learning). An error trial was followed by a lever activation trial in which a lever on the correct or the incorrect response side was automatically elevated at a preset time of 120, 220, 320, or 420 ms after tactile stimulation. This lever activation induced forepaw movement similar to that in a voluntary lever release response, and also induced body movement that occasionally caused elevation of the other forepaw. The effects of lever activation may have produced a sensation similar to that of voluntary lever release by the forepaw on the nonactivated lever. We found that the performance improvement rate was increased by the lever activation procedure on the incorrect response side (i.e., with the nonactivated lever on the correct response side). Furthermore, the performance improvement rate changed depending on the timing of lever activation: Facilitative effects were largest with lever activation on the incorrect response side at 320 ms after tactile stimulation, whereas hindering effects were largest for lever activation on the correct response side at 220 ms after tactile stimulation. These findings suggest that forced movements, which provide tactile and proprioceptive stimulation, affect sensory–motor associative learning in a time-dependent manner.

Learning in farm management: a New Zealand experience

Abstract

A universal goal of extension agents is the attainment of voluntary behaviour change in clients. Learning skills are critical to individuals that seek effective outcomes from behaviour change experiences. This paper reports on a study that estimated the cognitive changes occurring among a group of farmers, consultants and scientists in New Zealand. A model of the learning process directed the research. This model identifies two distinct components to learning: grasping information through conceptualisation or experience, and: transformation of information into knowledge, through reflection or experimentation. Individual clients are grouped into one of four distinct learning styles depending on the way they grasp information and transform it into knowledge. Research results detected learning preference and belief differences among the farmers, consultants and scientists in the group. The study suggests learning research methods assist extension agents plan and negotiate the specific behaviour changes that clients seek by implementing strategies that use learning preference and belief data. Researchers can improve approaches to technology development by exploring client needs using communication method's compatible with client learning preferences.     

Selecting learning tasks: Effects of adaptation and shared control on learning efficiency and task involvement

Complex skill acquisition by performing authentic learning tasks is constrained by limited working memory capacity [Baddeley, A. D. (1992). Working memory. Science, 255, 556–559]. To prevent cognitive overload, task difficulty and support of each newly selected learning task can be adapted to the learner’s competence level and perceived task load, either by some external agent, the learner herself, or both. Health sciences students (N = 55) participated in a study using a 2 × 2 factorial design with the factors adaptation (present or absent) and control over task-selection (program control or shared control). As hypothesized, adaptation led to more efficient learning; that is, higher learning outcomes combined with less effort invested in performing the learning tasks. Shared control over task-selection led to higher task involvement, that is, higher learning outcomes combined with more effort directly invested in learning. Adaptation also produced greater task involvement.     

How Dutch employees experience freedom of learning for work

This article focuses on the perceived freedom of Dutch employees to embark on workplace learning in terms of whether they feel it is “voluntary” or “compulsory”. The paper is based on the findings of a large international explorative survey carried out by the Workplace Learning (WPL) Research Network (RN2) of the Asia-Europe Meeting (ASEM) Lifelong Learning (LLL) Research Hub. The comparative study focused on employees’ quest for “freedom of learning for work”. This paper reports on the Dutch part of the research, the quantitative results of which seem to indicate that the freedom of learning for work is not as important to Dutch employees as might be expected. In a second phase, to investigate employees’ experiences of work-related learning in more depth, the Dutch researchers added a follow-up qualitative study, involving one-on-one interviews. In order to triangulate the results of the quantitative and qualitative research phases, the authors then added a mixed-methods sequential explanatory analysis. They assessed the quality of the collected data in both distinct phases by identifying converging results, which are useful for refining our understanding of learning for work. The paper draws both on rich insights into workplace learning based on this research as well as on theoretical literature which refers to concepts like motivation, subjectivity, work identity and agency in connection with the quest for freedom of learning.     

Does (Non‐)Meaningful Sensori‐Motor Engagement Promote Learning With Animated Physical Systems?

Previous research indicates that sensori‐motor experience with physical systems can have a positive effect on learning. However, it is not clear whether this effect is caused by mere bodily engagement or the intrinsically meaningful information that such interaction affords in performing the learning task. We investigated (N = 74), through the use of a Wii Balance Board, whether different forms of physical engagement that was either meaningfully, non‐meaningfully, or minimally related to the learning content would be beneficial (or detrimental) to learning about the workings of seesaws from instructional animations. The results were inconclusive, indicating that motoric competency on lever problem solving did not significantly differ between conditions, nor were response speed and transfer performance affected. These findings suggest that adult's implicit and explicit knowledge about physical systems is stable and not easily affected by (contradictory) sensori‐motor experiences. Implications for embodied learning are discussed.     

Examining the potential of web-based multimedia to support complex fine motor skill learning: An empirical study

Research on the utilization of the Web for complex fine motor skill learning that involves whole body movements is still scarce. The aim of this study was to evaluate the impact of the introduction of a multimedia web-based learning environment, which was targeted at a rhythmic gymnastics routine consisting of eight fine motor skills, into an undergraduate course in a physical education department, as a complementary tool to campus-based instruction. The impact was evaluated in terms of: acquisition of knowledge regarding the routine skills by students, improvement of students’ ability to execute the routine, and students’ responses to the environment. The study followed a pretest/posttest experimental design and involved 76 students randomly split into two groups: The Multimedia Web-based Learning Group (MWLG) students (N?=?38), who attended campus-based instruction on the routine and also used the environment in their own space and time, and the Traditional On-site Instruction Group (TOIG) students (N?=?38), who only attended campus-based instruction. The research data were gathered through student questionnaires and ratings of students’ performances. It was found that the use of the environment as a supplement to campus-based instruction increased the effectiveness of this instruction as regards the cognitive component of motor skill learning (i.e. acquisition of knowledge regarding the routine skills) and was well-accepted by the students, although it did not have any significant contribution to the physical component of motor skill learning (i.e. performance of the routine skills). These findings partially support the future wider adoption of multimedia web-based learning environments within physical education and other academic disciplines that involve complex fine motor skill learning. Relevant implications are discussed.     

Relevance,Application, and the Development of an Unlikely Theory

This paper advances the argument that motor learning research is not relevant to the needs and interests of motor skill teachers. The principal reason is that motor learning researchers in university departments of physical education have responded to calls for paradigmatic shifts that were intended for experimental psychologists, not necessarily for researchers from departments of physical education. As a result, motor learning researchers have concentrated their efforts on studying the mechanisms underlying motor performance rather than on devising and testing ways to improve motor performance. The body of knowledge produced by this approach has been based on experiments employing laboratory tasks and treatment conditions that lack fidelity to those appropriate or even possible in real-world teaching environments. Consequently, little knowledge has been produced that can be directly applied to the technical aspects of teaching. It also is argued that progress toward an applied thrust has been hindered because energies of the most capable researchers have been spent on attempts to develop a grand theory of motor skills, a theory that can never emerge until researchers attend to the essential preliminary task of defining motor skills.

Using outdoor learning to augment social and emotional learning (SEL) skills in young people with social,emotional and behavioural difficulties (SEBD)

ABSTRACT

Under-developed social and emotional learning (SEL) skills limit educational progress and make it difficult for children and young people with social, emotional and behavioural difficulties (SEBD) to form effective relationships with peers and ADULTS. This paper focuses on an SEL intervention set within an outdoor learning context. The research was practitioner led and used an action research (AR) approach to implement and evaluate the SEL intervention. Research participants (aged 12–13 years) were recruited from a UK special school and were all considered to have SEBD. The paper provides evidence for the specific SEL skills that participation in outdoor learning can enhance. The evidence suggests that outdoor learning can be an effective approach for educators wishing to augment the SEL skills of young people with SEBD.     

Students’ learning outcomes and peer rating accuracy in compulsory and voluntary online peer assessment

Peer assessment can be conducted online with rapid development of online learning technology. The current study was conducted empirically to investigate peer rating accuracy and student learning outcomes in online peer assessments, comparing compulsory and voluntary peer assessment. Section 1 (N?=?93) was assigned to the voluntary group and Section 2 (N?=?31) was assigned to the compulsory group. The results showed the voluntary group scored significantly higher than the compulsory group in the final task of the course, while there was no significant difference on the final task score increase. Students who participated in the voluntary group provided more accurate scores (i.e. peer rater accuracy) than those who participated in the compulsory group. The peer score leniency/severity rating, comparing peer assigned scores with the teacher assigned scores, were generally consistent with the peer rater accuracy results. The current study offers insights for researchers who are interested in studying the effect of online peer assessment activities. The results are also of interest for instructors who may want to conduct peer assessments in online courses and are choosing between compulsory and voluntary formats.     

Modeling imitation and emulation in constrained search spaces

Social transmission of behavior can be realized through distinct mechanisms. Research on primate social learning typically distinguishes two forms of information that a learner can extract from a demonstrator: copying actions (defined as imitation) or copying only the consequential results (defined as emulation). We propose a decomposition of these learning mechanisms (plus pure individual learning) that incorporates the core idea that social learning can be represented as a search for an optimal behavior that is constrained by different kinds of information. We illustrate our approach with an individual-based model in which individuals solve tasks in abstract “spaces” that represent behavioral actions, results, and benefits of those results. Depending on the learning mechanisms at their disposal, individuals have differential access to the information conveyed in these spaces. We show how different classes of tasks may provide distinct advantages to individuals with different learning mechanisms and discuss how our approach contributes to current empirical and theoretical research on social learning and culture.     

The relationship between perceived learning and satisfaction with college: An alternative view

Student and alumni reports of learning and development during college play an important role in research on educational outcomes. An intriguing finding of this research is the positive relationship between perceived learning and satisfaction with college. While studies have documented an association between perceptions of learning and satisfaction, the nature of the relationship is not clearly defined. This study evaluates two competing models of perceived learning and satisfaction. The first model represents a true relationship between learning and satisfaction, while the second treats the relationship as an artifact of a halo effect. Data came from subjects who completed learning and satisfaction questions as seniors and again two years after graduation. Analyses revealed that treating the learning-satisfaction relationship as an artifact of a halo effect provided the best representation of the data. Although not conclusive, results suggested that educational researchers and assessment practitioners should be careful in interpreting self-reports of learning and development, particularly as they relate to satisfaction with college.Presented at the Annual Forum of the Association for Institutional Research, Atlanta, Georgia, May 10–13, 1992.     

Mainly Openness: The relationship between the Big Five personality traits and learning approaches

In order to examine the relationship between broad personality traits and learning approaches, 852 university students completed the NEO-FFI [Costa, P. T., Jr., & McCrae, R. R. (1992). Revised NEO Personality Inventory (NEO-PI-R) and NEO Five-Factor Inventory (NEO-FFI): Professional manual. Odessa, FL: Psychological Assessment Resources] and SPQ [Biggs, J. B. (1987). The Study Process Questionnaire manual. Victoria: Australian Council for Educational Research], which assess personality and learning approaches, respectively. Seven previous studies were used to generate hypotheses on the relationship between these two measures, but only the positive link between Openness to Experience and Deep learning was supported by both correlational and structural equation modelling tests. Openness was also found to be negatively linked to Surface learning, but other Big Five traits were not saliently associated with learning approaches. Results indicate that the overlap between learning approaches and personality traits is lower than previously suggested. Implications are discussed.     

Education with production in Zimbabwe: an evaluation of teachers’ and pupils’ attitudes and perceptions

The terms community development and lifelong learning have been in use for several decades and refer to different areas within the field of adult education. This paper sets out to explore the relationship between these two concepts. It examines the ways in which community development work contributes to the development of an overall system of lifelong education. Recent writing on the idea of the learning society points towards a more holistic view of education, which acknowledges learning in all its forms and venues and which values the many and varied ways in which people learn. The nature of this rapidly changing society demands that individuals and communities take up this challenge, so that they can play their part in shaping the future. This paper is based on research which was carried out in the early 1990s, under the auspices of the Community Research and Development Centre, by one of the authors (RM) as part of a DPhil study. It was constructed with a view to exploring the need for a more holistic, integrated approach to meeting the educational needs of those involved in adult education, community development and community regeneration in Belfast. The research set out to investigate the relationship between the various forms of learning, through an examination of organizations engaged in providing formal, non‐formal and informal adult learning opportunities in Belfast. The results confirm that traditional providers of adult education no longer hold a monopoly over learning and that there is an emerging sector of community and voluntary organizations engaged in providing learning opportunities for adults in their communities. There is some indication that whilst the relationship between traditional and non‐traditional providers is complex, the opportunities for learning which they offer are complementary. The voluntary and community sector emphasizes issue‐based and action‐oriented learning within a democratic, participative culture. Non‐formal providers often seek to support such groups, by providing more structured learning situations. Their programmes frequently offer an alternative adult education to that of the formal providers, who are more concerned with traditional ‘liberal adult education’. Whilst formal providers may try to be more community‐based, they are severely confined by their bureaucratic, hierarchic structure. Informal providers, however, also offer opportunities for more formal adult learning opportunities, through links with formal providers. The existence of this network suggests the basis for a system of lifelong education, which incorporates the range of adult learning opportunities.     

The influence of a gesture-based learning approach on preschoolers’ learning performance,motor skills,and motion behaviors

This study developed a gesture-based learning approach to build a virtual interactive learning environment for preschoolers by combining a gesture-based computing device and a game-based learning model. Using sequential analysis, this study investigated how this approach influenced children’s learning performance, motor skills, and motion behaviors. A quasi-experiment was conducted with 142 kindergarten-level-3 preschoolers. The results showed that the gesture-based learning approach improved the students’ learning performance and motor skills compared with the traditional activity-based learning approach. The main learning pattern showed that the preschoolers controlled their body motion behaviors and movements to learning cognitive knowledge, which achieving a flow state that improved preschoolers’ learning performance and motor skills. In addition, the main motion pattern showed that the preschoolers interacted with the game by coordinating their body movement with the projected human skeleton’s movement, which improved their motor skills.     

Empirical evidence of the impact of lesson study on students’ achievement,teachers’ professional learning and on institutional and system evolution

In this article we review the evidence of the impact of lesson study on student learning, teacher development, teaching materials, curriculum, professional learning and system enhancement. We argue for lesson study to be treated holistically as a vehicle for development and improvement at classroom, school and system levels rather than as a curricular or pedagogical intervention. We illustrate the need for this approach to evaluating lesson study through a complex case exemplar which used Research Lesson Study (a form of lesson study popular in the UK and Europe) to develop learning, teaching, curriculum and local improvement capacity across schools initially involved in a two‐year mathematics curriculum development project that later evolved into three self‐sustaining, voluntary lesson study school hubs in London. We discuss resulting changes in culture, practice, belief, expectation and student learning. We argue as a result for greater policy level understanding of this expanded conception of lesson study as a vehicle in classroom, school and system transformation.     

Inclusive Learning: the Report of the Committee of Enquiry into the postschool education of those with learning difficulties and/or disabilities,in England, 1996

ABSTRACT

The Report, Inclusive Learning (1996), is the result of a three‐year enquiry into the educational needs of and provision for adults with disabilities and/or learning difficulties in England. It arose from the requirement of an Act of Parliament, in 1992, that the new national funding council for further education should ‘have regard’ for such students in all its work of funding, development and evaluation. The Committee commissioned some fundamental research into the nature and extent of provision, the actual and potential demand for further education and the current requirements of law, and also reviewed existing academic research (chiefly in English‐speaking countries). It took extensive evidence in many modes and, in particular, created a series of workshops in which the students and their advocates could speak for themselves. The outcome was the main Report and summary, together with six supplementary publications. The core of the Report is the notion of ‘inclusive learning’, which places the responsibility for providing appropriate education with the teachers, the managers and the system (ultimately, with society), rather than problematizing the student as one with a deficit. A good education system is not merely about offering access to what is available, but also the making of what needs to be available accessible: the moulding of opportunity. Thus the Report concentrates on a theory of learning and its educational consequences. It represents another step towards embracing students with learning difficulties and/or disabilities unequivocally within the general approach to learning appropriate for all students. This article summarizes the main lines of analysis and argument in the Report and its framework of recommendations to the Further Education Funding Council, teachers, managers, voluntary organizations and to the government.
