Extending the Scaffolding Metaphor

A brief overview overview is provided of how the scaffolding metaphor has been defined in educational contexts. This includes a discussion of what theories guide decision-making regarding what to scaffold as well as considerations as to whom or what does the scaffolding (human teachers, peers and tutors or computer tutors or support tools designed for learning environments). The scaffolding construct intersects instruction and assessment in that instructors assess learners to determine what type or level of scaffold is sufficient to help learners reach their potential. Such assessments are dynamic and ongoing and can occur through dialogue and social interactions with or without the use of technology. Hence scaffolds are provided when and where necessary but they are also removed when evidence of learning exists. This article describes how the contributors to this issue have extended the scaffolding metaphor to open-ended technology based environments. Empirical studies are reviewed with regard to how they extend the scaffolding metaphor in terms of the theories that guide the design of scaffolds, the metrics designed to assess how scaffolding affects learning and in terms of teaching scaffolding techniques to others.     

Scaffolding 6th graders’ problem solving in technology-enhanced science classrooms: a qualitative case study

In response to the calls to improve and deepen scientific understanding and literacy, considerable effort has been invested in developing sustainable technology-enhanced learning environments to improve science inquiry. Research has provided important guidance for scaffolding learning in mathematics and science. However, these reports have provided relatively little insight into how the different types of scaffolds can (or should) be implemented in dynamic, everyday classroom settings. In this qualitative case study, we examined how students solve scientific problems in technology-enhanced classrooms and how peer-, teacher-, and technology-enhanced scaffolds influenced student inquiry. The results indicated that students manifested distinct inquiry patterns when solving scientific problems and integrated different types of scaffolds to facilitate inquiry activities. These findings suggest that to support scientific inquiry in problem-solving contexts, technology-enhanced scaffolds are effective when supported by clear project goals, relevant evidence, peer- and teacher-assessments, and exemplars of knowledge articulation.     

Scaffolding learning for independence: Clarifying teacher and teaching assistant roles for children with special educational needs

Support for children with special educational needs (SEN) in inclusive classrooms, in many countries, continues to be provided by teaching assistants (TAs). Whilst they frequently take responsibility for instruction, they are rarely adequately trained and prepared. As TAs have ample opportunities for individualised and group interactions, this paper recommends scaffolding as the key theory to inform their practice. From a large dataset of interactions in mathematics and literacy lessons, episodes of TA scaffolding were selected. Using conversation analysis, three scaffolding roles emerged: 1) a support role that maintained learner engagement, on-task behaviour and motivation; 2) a repair function that focused on learning and fostered independence when children were in difficulty; and c) a heuristic role that encouraged students to use their own learning strategies. The paper concludes with implications for trainers and managers and how teachers can support TAs in implementing each role.     

Supporting collaborative inquiry during a biology field trip with mobile peer-to-peer tools for learning: a case study with K-12 learners

This study explores how collaborative inquiry learning can be supported with multiple scaffolding agents in a real-life field trip context. In practice, a mobile peer-to-peer messaging tool provided meta-cognitive and procedural support, while tutors and a nature guide provided more dynamic scaffolding in order to support argumentative discussions between groups of students during the co-creation of knowledge claims. The aim of the analysis was to identify and compare top- and low-performing dyads/triads in order to reveal the differences regarding their co-construction of arguments while creating knowledge claims. Although the results revealed several shortcomings in the types of argumentation, it could be established that differences between the top performers and low performers were statistically significant in terms of social modes of argumentation, the use of warrants in the mobile tool and in overall participation. In general, the use of the mobile tool likely promoted important interaction during inquiry learning, but led to superficial epistemological quality in the knowledge claim messages.     

Handling Small Talk at Work: Challenges for workers with intellectual disabilities

Interpersonal workplace interaction provides many challenges for workers with intellectual disabilities. While these workers are generally able to handle well the tasks required of them at work, the social interaction which others manage with ease often presents unexpected hurdles to such workers. This paper analyses tape-recorded workplace small talk collected in a range of New Zealand workplaces, including workplaces employing workers with intellectual disabilities. The topics, the distributional patterns, and the functions of small talk are described, and aspects of the management of small talk which may present problems to workers with intellectual disabilities are illustrated and discussed. Finally, some suggestions are provided concerning ways in which teachers and trainers may be able to assist workers acquire some of the basic sociolinguistic skills in small talk needed to operate effectively in their workplaces.     

Constituting the workplace curriculum

This paper advances some bases for a workplace curriculum. These are premised on conceptions of curriculum as intents directed to individuals’ progression towards full and effective workplace performance, yet whose enactment is shaped by workplace factors and is ultimately experienced by workers as learners. So whether the intentions will be realized is likely premised on the support (affordances) for their enactment by interests within the workplace. Workplace affordances, like those in educational institutions, emphasize the role that the norms and social practices that comprise workplaces play in regulating individuals’ engagement in and learning through work. The degree to which these affordances invite, structure, support, and guide participation, and are likely to engage workers in the kinds of thinking, acting, and learning required for effective workplace performance, is important for developing effective vocational practice. The conception of an ideal curriculum directed towards full participation is subject to the affordances of the interests of managers, co‐workers, and factors affecting production, as well as the intentionalities of worker‐learners themselves. These concepts may well provide ways of thinking about curriculum more broadly as participatory practices.     

The importance and use of targeted content knowledge with scaffolding aid in educational simulation games

While most current educational simulation games provide learners with gameplay experience to motivate learning, there is often a lack of focus on ensuring that the desired content knowledge is actually learned. Students may focus on completing game activities without learning the targeted content knowledge, thus negating the desired learning outcomes. We argue that to help students achieve improved learning performance, providing targeted content knowledge should be a specific focus in designing educational games; in addition, scaffolding strategies to promote the use of in-game contents should also be provided. Thus, the present study explores the effects and usage of providing three types of scaffolding aids in two versions of educational simulations with in-game contents. The results suggest that providing targeted content with scaffolding aid in educational simulation games helps students to achieve better learning performance.     

The learning experiences of health and social care paraprofessionals on a foundation degree

Foundation degrees have been developed in the UK as a means of meeting the learning needs of paraprofessionals in health and social care and the services within which they work in a cost‐effective fashion. Workplace learning is an intrinsic component to these degrees. Taking a socio‐cultural perspective, this paper examines how the students’ workplaces, life circumstances and sense of career trajectory shaped their learning experience and motivation. A small‐scale evaluation study, using semi‐structured interviews, focused on the learning experiences of a group of paraprofessionals enrolled in a foundation degree in health and social care. Data revealed fragmented employment patterns, underpinned by consistent vocational drives. While the study resonated with vocation, participants were ambivalent or lacked information about career progression. Workplace conditions, relationships and limited time shaped learning and coping strategies. A strategic and focused approach to student learning is required and includes attention to career pathways, workforce development strategy, the requirements of a range of stakeholders, workplace supervision and support for learning.     

Becoming a tutor: student scaffolding in a game-based classroom

Student interaction in school contexts is a topic that has been researched from many different perspectives. However, the role of students as tutors scaffolding other peers is not normally addressed, since studies are usually focused on the teacher. Moreover, considering the many technologies that can support students’ work nowadays, studies describing specific practices are still needed in order to understand the many possibilities and constraints that can emerge from the use of these tools in the field of education. This exploratory case study aims to extend research on scaffolding between students, presenting data from an ethnographic study where a commercial video game was introduced as part of the curricular activities. Analytically, the scaffolding metaphor is the departing point to describe in detail how the scaffolding process took place, focusing on its purposes and on the role of students as tutors. Our findings reveal how students offered mostly procedural scaffoldings, performing tutor functions such as highlighting relevant features, reducing levels of freedom or controlling the frustration. Results highlight that students can perform scaffolds, and this should be considered as part of the classroom design, making this process visible. Moreover, specific features of the video game enhanced these interactions, which should also be considered when designing game learning environments in the future.     

The purposes and processes of master's thesis supervision: a comparison of Chinese and Dutch supervisors

The number of international Chinese students enrolled in research programmes in Western universities is growing. To provide effective research supervision to these students, it is helpful to understand the similarities and differences in the supervision process between the host country and their home country. We explored which learning outcomes supervisors of master's theses aim for in two cultures, China and the Netherlands, and how they help their students to achieve these learning outcomes. Semi-structured interviews with 10 Chinese and 10 Dutch supervisors revealed, besides a strong resemblance, some clear differences between the two groups. For example, the Chinese supervisors aim to prepare their students for future jobs and use explicit assessment and regulation to monitor student progress, while the Dutch supervisors aim to enhance student well-being and use implicit regulation, emotional support and frequent posing of questions to facilitate student learning. Implications for cross-cultural and international education are provided.     

A Study on Human-Computer Interaction Mechanism in an Intelligent Tutoring System

Discussion is a common and important learning process. Involvement of a virtual agent can provide adaptive support for the discussion process. Argumentative knowledge construction is beneficial to learners’ acquisition of knowledge,but the effectiveness of argumentative scaffolding in existing studies is not consistent. Based on an intelligent discussion system, a total of 47 undergraduate students took part in the experiment and they were assigned to three different conditions: content-related plus content-independent scaffolding condition, content-related scaffolding condition, and the control condition. Under the content-related and content-independent scaffolding condition, the computer agent provided an idea from semantically different categories (content-related scaffolding) according to the automatic categorization of the current contributions, and further inquired the participants about their attitudes and reasons (content-independent scaffolding). Under the condition of content-related scaffolding condition, the virtual agent only provided semantically different viewpoints. Under the control condition, the subjects expressed their opinion independently without the participation of the virtual agent. Findings revealed that compared with the control group, when the virtual agent provided semantically different ideas (content-related scaffolding), the discussion breadth (number of categories) was improved and the subjects felt that they had a more comprehensive understanding of the problem. Compared with the content-related scaffolding condition, when the virtual agent provided semantically different ideas and further asked about the attitudes and reasons, the subjects expressed more agreement with these views, but mentioned fewer categories during the discussion. This study suggests that the content-related scaffolding can facilitate the cognitive processing effect relevant to the topic of discussion. When the content independent scaffolding is added, it can promote the argumentative processing, but may have a negative effect on the cognitive processing related to the topic discussed.     

Understanding work,learning and the remaking of cultural practices

This paper focuses on dualities in both the process and outcomes of participation in work. Firstly, the process of participation in work activities and interactions draws on contributions of both individuals and the social world in ways that are variably interdependent, that is, relational. The affordances of workplaces shape the array of experiences individuals are able to access and, they in turn, elect how they engage, construe and construct what is afforded them. Both the social and individual contributions are exercisable with different degrees of intensity, focus and intentionality, thereby making the process of participation in work a relational one. Secondly, and consistent with these processes, the outcomes of workplace participation also comprise dualities. These are individuals’ learning or change, on one hand, and the remaking and transformation of cultural practice that comprises work, on the other. In illuminating and elaborating these concepts, this paper draws upon the initial findings of an inquiry that is mapping the working lives of groups of three workers in each of four workplaces. The aim is to understand how these relational interdependences shape the participation, learning and remaking of work practices in these workplaces. Further, the paper identifies the exercise of both affordances and engagement for each participant within their workplaces. The findings emphasise the distinctive bases by which the groups of workers engage with their work and construct meaning and remake practice as a result of that engagement.     

Metacognitive and multimedia support of experiments in inquiry learning for science teacher preparation

ABSTRACT

Promoting preservice science teachers’ experimentation competency is required to provide a basis for meaningful learning through experiments in schools. However, preservice teachers show difficulties when experimenting. Previous research revealed that cognitive scaffolding promotes experimentation competency by structuring the learning process, while metacognitive and multimedia support enhance reflection. However, these support measures have not yet been tested in combination. Therefore, we decided to use cognitive scaffolding to support students’ experimental achievements and supplement it by metacognitive and multimedia scaffolds in the experimental groups. Our research question is to what extent supplementing cognitive support by metacognitive and multimedia scaffolding further promotes experimentation competency. The intervention has been applied in a two-factorial design to a two-month experimental course for 63 biology teacher students in their first bachelor year. Pre-post-test measured experimentation competency in a performance assessment. Preservice teachers worked in groups of four. Therefore, measurement took place at group level (N?=?16). Independent observers rated preservice teachers’ group performance qualitatively on a theory-based system of categories. Afterwards, experimentation competency levels led to quantitative frequency analysis. The results reveal differing gains in experimentation competency but contrary to our hypotheses. Implications of combining scaffolding measures on promoting experimentation competency are discussed.     

Supporting the education of pupils with profound intellectual and multiple disabilities: the views of teaching assistants regarding their own learning and development needs

Learning support assistants or teaching assistants play a vital role in the education of pupils with complex learning disabilities, routinely supporting students on a 1:1 basis without the direct supervision of teachers. Despite the responsibility afforded these classroom support staff, there appear to be few training programmes designed for this specialised role. This qualitative study, by Trudi Martin of the Manchester Institute of Education, was undertaken at a special school in England. The study explored the views of 17 teaching assistants and five teachers regarding the extent to which teaching assistant training equipped them to support pupils with complex learning needs. The findings illustrated that much of the training, including that on the Qualifications and Credit Framework, provided inadequate information and guidance. Without sufficient knowledge to underpin their practice, teaching assistants are impeded in the educational support they can give to pupils, who face significant learning challenges, with a resultant impact on their students' ability to learn and develop new skills.     

Student workload: a case study of its significance,evaluation and management at the Open University

Distance students are time poor and some drop out of their studies because they fall behind with coursework. This raises the issue of how course teams decide upon how many study hours should be included in a course. This article presents a number of Open University projects that have addressed student workload management and relates how learning design has incorporated these findings into advice for new module development. Moreover, the article also discusses how recent automatic feedback systems can motivate and support time-poor students when writing their assignments. This is an important finding as drop-out can occur when students are unable to devote the necessary time to their summative assessments and drop out of the learning process.     

The Impact of Scaffolding and Student Achievement Levels in a Problem-based Learning Environment

This study examined how scaffolds and student achievement levels influence inquiry and performance in a problem-based learning environment. The scaffolds were embedded within a hypermedia program that placed students at the center of a problem in which they were trying to become the youngest person to fly around the world in a balloon. One-hundred and eleven seventh grade students enrolled in a science and technology course worked in collaborative groups for a duration of 3 weeks to complete a project that included designing a balloon and a travel plan. Student groups used one of three problem-based, hypermedia programs: (1) a no scaffolding condition that did not provide access to scaffolds, (2) a scaffolding optional condition that provided access to scaffolds, but gave students the choice of whether or not to use them, and (3) a scaffolding required condition required students to complete all available scaffolds. Results revealed that students in the scaffolding optional and scaffolding required conditions performed significantly better than students in the no scaffolding condition on one of the two components of the group project. Results also showed that student achievement levels were significantly related to individual posttest scores; higher-achieving students scored better on the posttest than lower-achieving students. In addition, analyses of group notebooks confirmed qualitative differences between students in the various conditions. Specifically, those in the scaffolding required condition produced more highly organized project notebooks containing a higher percentage of entries directly relevant to the problem. These findings suggest that scaffolds may enhance inquiry and performance, especially when students are required to access and use them.     

Getting the Most From Your Interactive Whiteboard Investment: Three Guiding Principles for Designing Effective Professional Development

The adoption of interactive whiteboards (IWB) in many schools outpaced the delivery of adequate professional development on their use. Many teachers receive IWBs without adequate training on methods to use the technology to improve their instruction. Consequently, IWBs remain an underutilized resource in many classrooms. Teachers who are given IWBs require purposeful, scaffolded, and sustained professional development to maximize the IWB's potential. This article identifies three promising professional development practices for teaching educators how to use IWBs effectively. The literature describing effective technology professional development suggests it should (1) build efficacy by scaffolding the instruction of new tasks, (2) establish long-term collaborative partnerships among teachers, and (3) include positive supervision that encourages teacher self-reflection and measures student engagement with digital media using the IWB. Professional-development designers can increase the effectiveness of their instruction by incorporating these principles into their training.     

Talking up learning at work: Cautionary tales in co‐opting everyday learning

Learning in workplaces is always mediated through talk. It is tempting for management to seek to utilise everyday talk as part of learning and therefore enhance productivity. This paper examines the responses of workers to interventions that aim to formalise informal conversations at work as part of an explicit workplace learning strategy. It draws on interviews with managers and workers in a public sector organisation to examine their experience of these practices. The paper raises questions about whether interventions in the name of fostering informal learning may well be hindering what they seek to promote.
