Experiential Learning in Action: a program for preparing educators for health professionals

Education is centre stage in current UK government initiatives to promote multi-agency team work. This paper draws on a research project which explored the way in which multi-disciplinary teams work and learn together in their practice with children, to consider the implications of ‘joined-up’ practice for theorizing dilemmas of knowledge creation and identity transformation for professionals in multi-agency teams. The paper focuses primarily on the experiences of education professionals. We exemplify some dilemmas of ‘joined-up’ team participation in specific workplace activities involving knowledge exchange. We then explore the impact of belonging to multi-agency teams on professional roles, identities and learning. The paper then summarizes strategies which professionals used for resolving dilemmas around learning and knowledge creation, and considers how participating in shared workplace activities might enable or constrain professionals to consoli date their professional identities and learning. Drawing on theoretical research into workplace participation and professional learning, the paper examines implications for theorizing the professional identity of teachers in multi-agency team work, within a systemic model that takes account of: creating new knowledge and practice; enhancing professional identity; and building inter-professional communities.

Evaluating a large-scale implementation of Assessment for Learning in Sweden

This study reports on a large-scale implementation of Assessment for Learning (AfL) in a Swedish municipality. The implementation was founded on two principles: (1) teaching should be informed by educational research; (2) to be successful teachers’ professional development needs to be based in everyday classroom practice. From these principles, AfL was chosen as a strand of educational research to inform teaching and ‘Teacher Learning Communities’ were chosen as a vehicle for professional development and for implementing AfL practices. Findings indicate that the project has been successful in bringing about a change in how teachers talk about teaching and learning and in changing teachers’ pedagogical practice towards AfL. Findings also suggest that AfL practices are mostly teacher-centred, which means that the teachers still take most of the responsibility for the assessment. This leads to high workload for the teachers and may also hinder students from taking responsibility for their learning.     

Design and implementation of an intelligent virtual environment for improving speaking and listening skills

In this paper, we present an intelligent architecture, called intelligent virtual environment for language learning, with embedded pedagogical agents for improving listening and speaking skills of non-native English language learners. The proposed architecture integrates virtual environments into the Intelligent Computer-Assisted Language Learning. This architecture supports visual, auditory, and haptic channels of interaction. It allows pedagogical ideas about language skills to be implemented and validated with a minimum design time. Moreover, we design a computational model to evaluate learner's proficiency level, and an automatic adaptation mechanism which adjusts to the learner's learning curve. We have implemented two scenarios based on the proposed architecture to teach learners how to communicate in public places such as airports and TV stores. Inputs to this system include learner's speech and hand motion, and outputs include graphical scenes, force feedback, and speech by a few embodied agents. Throughout interactions, agents discover the proficiency level of the learner and customize the level of communication complexity accordingly. The system is tested on 10 subjects. Experimental results show 14% increase in the number of proper replies, 3% decrease in grammatical errors, 16% decrease in pronunciation duration, and 11% increase in learners' proficiency level within three trials.     

Learning Prolog in a schema-based environment

A set of basic construct Prolog schemata are presented as the basic constructs of a structured Prolog for recursive list processing. Prolog schema hierarchies are given that group classes of Prolog programs within each of the basic construct Prolog schemata via most-specific schemata which high-light their similarities and differences. A schema-based instructional approach based upon this classification of Prolog programs is provided as a method of introducing recursion to novice Prolog programmers. The incorporation of this approach to teaching recursive Prolog programming in an intelligent tutoring system is presented. Finally, a schema-based Prolog programming environment embedding this tutoring system in addition to a standard Prolog development system is proposed which promotes the acquisition and use of structured programming constructs in Prolog.

Learning in the outdoor environment: a missed opportunity?

In 2001, the Welsh Assembly Government announced proposals for a Foundation Phase for children aged three to seven years. The Foundation Phase framework promotes a play‐based approach to children's learning in both indoor and outdoor contexts and places children's well‐being and their personal and social development at its core. While the framework is currently being piloted across Wales, full implementation will not take place until 2010; for many schools, then, this is a time of transition. This paper discusses the findings of a research project that aimed to document the current use of the outdoors by a group of early years teachers working in South Wales. Drawing on data from interviews and observations conducted in four schools, it is suggested that the teachers missed many of the opportunities afforded by the outdoor environment to enhance children's learning. The paper considers the reasons why this might be the case and comments on the distinction, apparent in two schools, between what was seen as ‘normal’ and ‘special’ outdoor activity.

Learning novel mathematical concepts in a computer-enriched environment

There is widespread belief that computers should be used for the teaching and learning of mathematics. Research indicates that computers are primarily used in mathematics classes: (1) to reinforce previously taught concepts, (2) to allow students to construct computer programs to simulate mathematical techniques known to the student and (3) to explore mathematical microworlds encompassing mathematical ideas and concepts normally known to the student. Furthermore, it is said that pre-service teachers should experience the learning of mathematical ideas and concepts of which they had no prior experience in environments in which computers are just one of the resources available for exploring and experimenting with these ideas and concepts. How should these learning environments be constructed so that pre-service teachers are sensitised to the value of doing mathematics in such environments? Is a student's understanding of novel mathematical concepts enhanced when s/he explores it in a computer-enriched environment? An experiment with pre-service teachers was carried out in a college of education for blacks in South Africa. This article describes the insights gained from this experiment.     

Teachers’ beliefs about issues in the implementation of a student-centered learning environment

Teachers’ implementation of technology-enhanced student-centered learning environments (SCLEs) will be affected by their beliefs about effective practices. In order for student-centered programs to be used as intended, designers must be aware of the key issues that will shape their implementation and the beliefs teachers hold about these issues. This case study examined 15 teachers’ beliefs about student-centered learning as they implemented Alien Rescue, a computer-based program for middle school science that was designed to create a SCLE in the classroom. Considerations for the design of similar programs are offered.     

Learning management system implementation: a case study in the Kyrgyz Republic

ABSTRACT

In this paper, the determinants of the intention to use online learning management system (LMS) among students in one of universities in the Kyrgyz Republic were studied, using quantitative and qualitative analysis. A total of 541 responses from students, enrolled in online courses during the fall and spring semesters 2016–2017, were used to examine students attitude toward online education. In addition, interviews with six instructors were conducted. Results showed that success of students in e-courses depend on year of education and the academic major of students. Factors, defined in the scope of this work, namely, technical characteristics of LMS, ease of use, feedback options of LMS and advantages of LMS use, were also found to be significant for students in their success in online courses. In interviews with instructors, three main points were highlighted, namely, problem with students’ perception of online courses, lack of online education experience among instructors and administrative issues.

Instructional Rounds as a professional learning model for systemic implementation of Assessment for Learning

The purpose of this research was to examine the implementation of a professional learning project aimed at building educators’ knowledge and skills in assessment for learning (AfL) within two school districts in Ontario, Canada. Specifically, the research examined the value of a two-tier Instructional Rounds (IR) professional learning model. This professional learning model was unique because it engaged both teachers and principals in collaboratively learning and implementing AfL strategies in order to develop systemic capacity in assessment. In total, 12 principals, 48 teachers, two superintendents and two school district assessment consultants participated in the study. Data were collected through observations of IR sessions, classroom observations, interviews, IR session reflections and a post-project survey. Findings from this study report on positive changes in teachers’ and principals’ conceptions and implementation of AfL as well as on the value and challenges of IR as a professional learning model. The paper concludes with a discussion on developing systemic capacity in AfL through an IR model of professional learning.
