Oral and Written Reflection in Practice Management: An Action Research Approach

Reflection in Practice Management (PM) favoured the integrated approach where learners had to critically reflect on the study material, assessments and tasks throughout the year and to integrate their experiences in a meaningful manner that would demonstrate their development and learning over the year. Reflection in the form of portfolios focused on personal development and individual learning rather than on achieving a general set of course outcomes. But assessment of these portfolios revealed no real evidence of reflection or critical thinking. This study suggested that learners be assessed orally so that their reflections could come alive and so that the educator could learn from the assessment to restructure or re-curriculate where necessary. This study found that although the orals were not a preferred form of assessment, they contributed successfully to informing the written critical and reflective thinking in the portfolios. Using an action research approach, enabled us to not only address a fundamental problem that the educators and learners were battling with—how to encourage and indeed teach learners to think critically and to reflect, but it also showed the educators how to solve problems or seek solutions to didactic problems in their own classrooms. The recommendations in this paper may therefore inform courses other than PM that use reflective practice, critical thinking or portfolio assessments.     

Oral Assessment: Preparing Learners for Discourse in Communities of Practice

Grounded in social constructivism within an action research framework, this paper locates oral assessment within situated learning and focuses on the construction and assessment of knowledge within communities of practice. This study found that by simulating situations for undergraduate learners to familiarize them with the discourse practices before they are expected to interact on a more professional level within communities of practice, oral assessment enables exposure to the cultural models and the sociocultural groups that can socialize them into these. It is recommended that these experiences be guided by their educators and more capable peers so that learning can be scaffolded.     

Encouraging Intercultural Communication Using an Action Research Approach

South Africa is 15 years into democracy, but difficult dialogues about race, ethnicity, and other cultural differences are hindered when students are developmentally unprepared to handle them. Although institutions of learning have been painfully aware of the racial, cultural and ethnic divides on their campuses, no real strategies or policies have been put into place to ensure integration. This study started with problems that my colleagues in the Faculty of Science at a university in South Africa were experiencing with the lack of interaction and communication among the first year students in their large and diverse classrooms. They were also concerned that their students did not know how to deal with diversity and they wanted to graduate students who would be successful in their professional careers in a multicultural environment. This study found that using an action research approach was particularly successful in teaching Communication and in encouraging intercultural communication as lessons learned could be built upon or learned from in order to plan the next phase of intervention. The continual interactions during the various phases typical of the action research approach used, enabled the unearthing of feelings, problems and issues which would otherwise not have surfaced in the normal classroom where students are merely lectured. By transforming method and methodology, students and educators were exposed to new and different ways of being. This paper therefore reports on how a course in Communication was developed to facilitate communication and interaction between the different cultures and race groups in a Science classroom using an action research approach.     

Learning by Action Research: A Policy for School Development

In this article I define a project organization as action research. Thus defined, the approach presents a method for experiential learning among educators who develop as learners in an educational setting. Second, the approach describes a method for focusing on research related to change in classroom didactics brought about by the mediating instruments educators discover and use so as to overcome their own learning anxiety. Third, action research and academic investigation are described as a method for integrating theory with practice. Finally, action research is outlined as an effort for social justice—the way knowledge usually develops by social construction.     

Using Action Research to Improve Communication and Facilitate Group Work in a Multicultural Classroom: A South African Case Study

This study started with problems that my colleagues (and I) were experiencing with interaction and intercultural communication among students in our diverse classrooms. Educators were also experiencing difficulties in motivating students to work effectively in groups. The purpose of this paper was to seek solutions to these problems by exploring variations of the group oral assessment structure in a multilingual and multicultural context. Four phases of assessments were conducted at two tertiary institutions in South Africa using a combination of action research and a participatory approach. Not only did this study succeed in addressing the problems but it also revealed the added benefits of using an action research methodology.     

You are Seldom Born with a Drum Kit in Your Hands: Music Teachers’ Conceptualizations of Knowledge and Learning Within Music Education as an Assessment Practice

Due to an increased demand for evaluation and accountability, the focus on assessment in public education has become stronger. Already leading to teachers’ deprofessionalization, another risk is assessment leading to criteria compliance and becoming a tool for measuring teaching quality. Those whose learning is affected are thereby not only students, but also teachers. One major factor to restore professionalism and focus assessment on learning is to change practitioners’ ways of thinking and not only their behaviour. Therefore, a group of seven music teachers and a researcher in music education have carried out a research and development project using participatory action research as approach as well as method. This article explores and presents these upper secondary school music teachers’ conceptualizations of musical knowledge, learning and educational communication working with peers. Using Deweyan pragmatism as a lens to interpret the qualitative data, the results show that while a professional language does exist, the music teachers’ conceptualizations of musical knowledge and learning and educational approaches differ. A key aspect for the teachers to develop their professional language, concepts and assessment practices is the teachers’ opportunities to communicate—both factual as well as perceived.     

Using an Action Research Framework to Explore Assessment: A South African Case Study

This article is a reflection of my first experience with action research in trying to devise a system of assessment that would benefit both first and second language speakers of English in an assessment system that is plagued by its separatist past. In this paper, I discuss an action research study on oral assessment implemented at two tertiary institutions in South Africa. The actual details of each phase of the assessments are not reported on, but the methods used to facilitate the processes are. The findings and adaptations after each phase of the assessments are discussed to show the effectiveness of using an action research methodology.

Using Critical Social Heuristics and Project-Based Learning to Enhance Data Warehousing Education

The aim of this paper is to demonstrate how project-based learning can be used from a critical systems perspective in data warehousing education. Data warehousing is a discipline in information technology focusing on providing data-driven decision support systems for strategic decision making. In this study we used action research from a critical (emancipative) perspective to reflect on our current instructional design of the data warehousing module before redesigning it to better serve the needs of the involved and affected. We used critical systems heuristics and project-based learning as frameworks of understanding to guide our intervention. Project-based learning is a learning/teaching approach aimed at organising the learning experience in terms of a project. We used written interpretive interviews in the diagnosis and evaluation of success phases of our action research cycle. Our reflection is according to the action research model of Checkland reflecting on our success in the area of application (data warehousing instruction) as well as our methodology (action research from a critical social theory perspective) and our framework of ideas (project-based learning and critical social heuristics).     

A Review of Diagramming in Systems Practice and How Technologies Have Supported the Teaching and Learning of Diagramming for Systems Thinking in Practice

The educational process arguably involves a mediated discourse between teachers and learners to aid sense or meaning making for both parties. That mediation, particularly in distance teaching models, is often done through the use of educational resources, whereby teachers develop and/or select the educational resources which the learners then study or engage with through purposeful activities. Some issues or topics are so complicated or complex that words or numbers may be insufficient to represent the meanings contained within them and this is particularly relevant to systems studies which examine complex adaptive systems. Equally diagrams can break out of the linear and systematic nature of printed text to show non-linear and systemic features. This latter trait has been enhanced through the emergence in recent years of digital technologies whereby hypertext and other web applications now make it easier to create dynamic and/or interactive diagrams. And yet there has been little recent research into the influence of such technologies on the learning of systems diagramming skills at a distance. These issues are examined through a review of the literature and the reporting of previously unpublished surveys within The Open University on the value of diagrams to systems studies and the role of technology in influencing the study of diagramming in the teaching of systems thinking in practice. This review indicates that diagrams are seen as an important feature of systems studies and that digital technology can be effective in supporting the teaching and learning of systems diagramming skills at a distance. It also notes that new investigations are needed to examine whether more recent developments in digital technologies have made them more effective and/or efficient for teaching and using such skills in practice.     

The Emergent Properties of SSM in Use: A Symposium by Reflective Practitioners

Two careers, in industry and in university teaching at postgraduate level, have led to the development of Soft Systems Methodology (SSM) in a 30-year program of action research. The most cogent comments on SSM come from reflective practitioners, and in this symposium I have asked eight such users of SSM to reflect on their experience and to address the question of what it is that happens when the approach is used in real-world problem situations. Their responses reflect their different backgrounds, experience, and ways of working, but a broad general picture emerges. This suggests that SSM (whose process does not necessarily have to be made explicit to participants in a study) can engender a process of on-going (cyclic) coherent structured learning which feels natural, and which can surface previously unexamined assumptions, thus creating an arena in which accommodations can emerge which enable and motivate "action to improve" to be taken.     

Community Service Learning and the Emergence of Systems Thinking: A Teacher Education Project in an Urban Setting in Turkey

This study explores how community service learning experiences are reflected in the cognition of prospective teachers. Initial thoughts related to the experience are analyzed in relation the emerging thoughts throughout and after the experience. The study explored the thoughts of 15 prospective foreign language teachers related to their participation in a community project. The participants tutored students with visual disabilities at a learning center in an urban setting in Turkey. As part of the community-based field experience, participants worked with the learners with visual disabilities over a 16-week period. For this study, multiple reflective narratives of experience were collected from each individual. The goal for the collection and analysis of these narratives was explore the participants’ thinking patterns throughout the project and encourage them to reflect on their experience. The analysis of participants’ discourse relied on analysis of co-occurring lexemes in sample utterances text with descending hierarchical classification and correspondence analysis. The main themes that reflected the thoughts of the participants were related to (a) visions for community service, (b) teaching students with visual disabilities, (c) reflections in action, (d) awareness through interactions with difference, (e) interactions with people during community service, and (f) efforts to contribute to the project site. These themes were discussed in relation to the contribution of community service learning and the emergence of systems thinking among program participants.     

Environmental Education: Enhancing Learning and Awareness Through Assessment

Environmental issues are rapidly gaining momentum globally as humans try to find sustainable solutions to the effects of climate change, carbon emissions, and the actions of human-kind (see Olver, Blacklist those who ‘greenwash’. Companies must walk the talk regarding climate. The Times, 2011a; The weather warriors’ war. Real change will come when a few good men and women say ‘enough is enough’. The Times, 2011b). To enhance learning and awareness of environmental issues among Environmental Education students and the community at large, this study situated assessments within communities of practice around the university. Using action engagement within action research students had to work with insiders from the community to identify, formulate action or intervention plans and find solutions to problem situations in the community. Using action engagement within action research in this study definitely enhanced student’s knowledge of their community’s problems. Their personal involvement and the cyclical approach adopted, enhanced students’ emotional understanding and gave them an insider perspective into the situations and problems that required intervention; and trust was built between the students and members of the community as they worked together to accomplish a common goal.     

Toward Fostering Systems Learning in Organizational Contexts

This article explores the ways in which the process of systems learning can be nurtured in organizational contexts. I posit that in order to mobilize systems learning at the individual, group, and organizational levels, an integrated, holistic approach must be pursued. It is suggested that the challenge of not only teaching the systems thinking concepts but also using their actual applications in practice is more than just an issue of pedagogical improvement. The cultural and material issues integral to the use of systems thinking must be taken into consideration as well. I argue that our efforts to improve our pedagogical practices to foster systems learning in organizational contexts can benefit from the social constructivist perspective, which represents a system of ideas about learning. The qualities of systems pedagogy resided in social constructivism are proposed as a framework to think with in designing the meaningful systems learning activities. This article also discusses how to create the cultural and material environments in which the process of systems learning can be nurtured.     

The First-, Second- and Third-Person Dynamics of Learning History

Learning history is a well delineated action research process consisting of consecutive stages of inquiry where groups and individuals engage in learning and reflecting on their past shared, but often multiple, experiences as these are recorded in a ‘learning history’. Learning history has much in common with other forms of action research in that it configures first-, second- and third-person processes of inquiry in a particular way and enacts research qualities of rigour, relevance and reflexivity. Yet these and other links have as yet been tacit and under articulated - resulting in learning history often conceived as a distinctive linear method with the practice of learning history likewise confined. This reflective article opens out and makes explicit the inherent first- second- and third- person dynamics of learning history. These dynamics are explored from the point of view of different actors – the historian, the participant and the reader - in a learning history process and connections to a general empirical method are made. Finally questions of quality in a learning history are discussed. The aim of this article is to establish firmer methodological foundations for the learning history approach and to provide practical insight into how action researchers might engage more readily in learning history work.

Improvements in Introductory Programming Course: Action Research Insights and Outcomes

Programming is a rewarding and yet demanding field in the ICT labormarket, but it is considered a challenging and difficult area of learning for significant numbers of novice programmers. As a result, high attrition rates from introductory programming (IP) courses are reported despite extensive research which attempts to address the issue. In this research, an action research methodology was used with three cycles to investigate and improve the teaching and learning process of the IP course. There were nine activities performed during the span of these three cycles. All three entities of the didactic triangle (student, instructor, and content) together with learning context were incorporated into the research design to understand the problem better and execute the proposed solution. The result shows that three cycles of the action research methodology helps in understanding and improving the students learning outcomes in the IP course. Moreover, the attrition rate was also reduced in the IP course.     

Research and Reflection: Potential Impact on the Professional Development of Undergraduate Occupational Therapy Students

In occupational therapy education in South Africa, community service (CS) focuses learning opportunities during fieldwork placements. CS therefore enabled the researcher to utilise successive small scale research projects to guide learning of students during fieldwork while simultaneously developing the occupational therapy service at a residential care facility. This community setting provided a powerful environment through which research, in combination with opportunities for reflection, contributed to nurturing skills needed by these future health professionals. A technical action research (AR) approach incorporated AR cycles and opportunities for structured reflection. Therefore situations were created for the students to embrace experiential learning. Experiential learning in the form of anticipatory reflection, reflection-in-action, reflection on reflection and retrospective reflection impacted on the quality of the students’ work. Besides encouraging unique leaning opportunities for students when engaging in research during their fieldwork placement, engagement in AR cycles simultaneously improved service delivery to residents in the facility. Key benefits of this investigation were that fieldwork education utilising AR cycles within a CS situation promoted students to identify voids in their theoretical background as well as practice skills; to apply reflective practice that could contribute to their personal and professional development; and to utilize learning opportunities optimally. Despite positive gains showed by this study, the role of power relations between the researcher as fieldwork educator and the students prohibited the AR cycles from being more emancipatory in nature and should be addressed in follow-up studies.     

Distance Education: A Reflective Action Research Project and Its Systemic Implications for Higher Education

This reflective action research study examines faculty experience with distance education. Distance education has become increasingly of interest in higher education and is seen by many as the opportunity for systemic change in higher education. This study is a reflective action research project which examined the author's experiences teaching a distance version of a basic instructional design course at the same time as teaching a residential version of that same course. The examination finds significant faculty issues that emerged during the experience and specifically found concerns with the distance education learner. In the end, the study finds that as a tool for systemic change of higher education, distance delivery will have to engage faculty with their concerns in more substantive ways than they have to date. In essence, this study asserts that the current demands on distance educators are not motivating for traditional faculty members because of increased time demands, lack of traditional rhythm, lack of personal contact with students, and less evident interest among distant students in the areas that faculty value.

Predicting Trend of High Frequency CSI 300 Index Using Adaptive Input Selection and Machine Learning Techniques

High-frequency stock trend prediction using machine learners has raised substantial interest in literature. Nevertheless, there is no gold standard to select the inputs for the learners. This paper investigates the approach of adaptive input selection(AIS) for the trend prediction of high-frequency stock index price and compares it with the commonly used deterministic input setting(DIS) approach.The DIS approach is implemented through computation of technical indicator values on deterministic period parameters. The AIS approach selects the most suitable indicators and their parameters for the time-varying dataset using feature selection methods. Two state-of-the-art machine learners, support vector machine(SVM) and artificial neural network(ANN), are adopted as learning models. Accuracy and F-measure of SVM and ANN models with both the approaches are computed based on the high-frequency data of CSI 300 index. The results suggest that the AIS approach using t-statistics,information gain and ROC methods can achieve better prediction performance than the DIS approach.Also, the investment performance evaluation shows that the AIS approach with the same three feature selection methods provides significantly higher returns than the DIS approach.
