This paper examines the relationship between the independent learner and computer based learning resources, which continue to be integral to educational delivery, especially in the training sector. To place interactivity in context, the first part of the discussion focuses on the major dimensions of interactivity and the different ways they have been characterised in computer based learning environments. These dimensions demonstrate the many ways that interactivity can be interpreted and the critical role that design and development plays in creating effective interactive encounters. The second part of the paper reviews the way storytelling structures and narrative have been promoted as effective strategies for enhancing comprehension and engagement in computer based learning applications. The way in which the interactivity and narrative are linked becomes critical to achieving this outcome.
Extending the use of a narrative within interactive media to include elements of performance and theatre, the third part of the discussion proposes that by conceptualising the learner as actor, a form of learner-designer communication can be established. Integrating this approach with elements of conversational and communication theory provides a context in which the learner-computer interface is transcended by that of learner and designer. Enabling this form of communication with the independent learner is suggested as a means to enhance computer based learning environments.
In contrast interactivity is portrayed as the distinguishing factor of the new media, with the assumption that "interactivity in a computer product means that the user, not the designer, controls the sequence, the pace, and most importantly, what to look at and what to ignore" (Kristof & Satran, 1995:35). This implies to some extent that the value of the material is based on the user's motivation and objectives. However, Holmes (1995:1-2) identifies that the structure or design of the material is equally critical and that the interactivity embodied within a computer is dependent on that design:
Interactivity is the ability of a new media program, web site, kiosk or multimedia presentation, to allow its user to control the content in some manner ... Interactivity must involve, engage, and motivate the user to explore the product ... Bad interactivity happens. The user can be frustrated by muddled organization, too much information or poor instructions ... Interactive properties of new media should provide opportunities for the user: exploration, discovery, and collaboration. Well conceived interactivity knows its audience, understands their knowledge base, and uses terms and phrases that are commonly understood by the audience. Good interactivity also takes into account the situation of the audience.Examining this perception reveals a number of major factors - first the user must be able to control the application and the application must be designed to engage the user; second the user must have some freedom and third the application must be designed for a specific audience. Interactivity, at least from this perspective, is partly about what the user does and part about how the application is designed. However, this perspective is at odds with the notion of the individual learner - are designers able to create applications that will match each member of a target group?
In proposing a nascent theory of interactivity Jaspers (1991) identified different levels ranging from the linear (information delivery) to the communicative (student initiated). However, the success of such a theory was dependent on the relationship between designer and developer and the perceived role of the learner. Emphasising the benefits of a learner centred environment the problematic and contradictory nature of interactivity was noted:
In fact, the expression of interactive delivery is contradicto in terminis from the viewpoint of interaction and emancipation. Delivery implies a unidirectional relationship. In full interaction there can be no one sided relation; the student is not just at the end of a chain but also at its beginning. (Jaspers (1991:21)To what extent the learner can play a proactive role while working with computer based learning resources becomes critical to the success of such applications and is considered in the final part of this paper. A related issue concerns developing a common understanding of interactivity. Schwier & Misanchuk (1993) refer to the levels defined in the literature as arbitrary and non-descriptive. Aldrich, Rogers & Scaife (1998) refer to interactivity as ubiquitous and Plowman (1996b) considers the excesses of physical interactions as gratuitous. The confused state of interactivity was also acknowledged in the following:
Though lauded by many for its ability to handle user inputs, there is little consensus with regard to the design of human computer interactions. Indeed, disagreement even exists about the meaning of the terms interactive as applied to emerging technologies. Researchers have described fundamentally different perspectives on the roles of interactions, ranging from facilitating lesson navigation to supporting encoding of specific lesson content ... Research on interaction methods may be among the most critical ... The domain of possibilities has broadened substantially, yet little research has been advanced which might guide their design. (Hannafin, Hannafin, Hooper, Rieber & Kini, 1996:385)A critical approach to assessing interactivity was presented by Rose (1999) who, given the various taxonomies of interactivity coupled with an apparent lack of denotative value, set about a deconstruction of established understandings. Critical of the "good" versus "bad" mentality that pervades the field (active not passive, learner control not program control, constructivism not instructivism, hypermedia not linear delivery), Rose (1999:45) presented an interesting scenario that contradicts many perceptions of interactive environments:
Texts addressing the subject of interactivity ... privilege representations of highly motivated learners exploring the wonderful worlds of interactive instructional programs and making exciting discoveries. However, it is by virtue of a deconstructive reading that we can begin to see the shadowy figure of the disavowed other lurking behind these wide eyed adventurers: the shadow of a child sitting mesmerised and immobile before the computer, only her index finger on the mouse moving occasionally as a stream of images passes in a more or less predetermined sequence before her eyes.Focusing explicitly on control Rose (1999) observed that although the words "learner control" have been interpreted as control by the learner, while grammatical comparisons (for example crowd control, weight control) tend to imply the opposite - control of the learner! The conclusion provides reinforcement for maintaining and extending research into making interactive learning work better:
That the field of educational computing is in need ... of internal critique is surely suggested by the fact that the very quality which is said to make computers unique and to justify their instructional use continues to defy definition. (Rose, 1999:48).There remains a paradox of interactivity. On the one hand it is portrayed as an integral and critical component of computer based applications and on the other as ill defined, deceptive and difficult if not impossible to implement. Is interactivity the hero or villain of achieving success through computer based learning? To address this question the following dimensions of interactivity demonstrate its multi-faceted nature and the issues that are essential to consistently implementing effective interactions within computer based structures.
However, the value of the control provided to the learner is dependent of the consequences of the learner actions and the extent to which the application responds or adapts to the individual learner's actions.
Interactive lessons are those in which the learner actively or overtly responds to information presented by the technology, which in turn adapts to the learner, a process more commonly referred to as feedback. The point is that interactive lessons require at least the appearance of two way communication. (Jonassen 1985:7)In this instance the adaptive capacity of the program is viewed in terms of a combination of the learner response and computer feedback, which in turn provides a form of communication. This process of question-response-feedback has been perceived by many writers as the essence of interactivity for computer based learning. For example, Steinberg (1991:100) observes that "question-response-feedback sequences help learners attain higher cognitive skills as well as factual information" and links the two elements of control and adaptation to the mechanics of interacting with the system (navigation) and the acquisition of knowledge and skills (learning). These descriptions identify two major components of interactivity - those which are program initiated and tell the learner what to do and those which are learner initiated, such as requests for help, information or explanation. This balance is also perceived as a means to achieve the goal of emulating human-human interaction in the computer medium, and thereby enhancing participation in the learning process.
Interactivity, or instructional features that promote active learning, provides critical support for increases in learning and retention in all educational activities ... Interaction implies active learner participation in the learning process ... an essential condition for effective learning ... failure to build interactivity into your program will reduce learning and retention.This comment reflects a shift in emphasis from the overt nature of interactivity to the extent to which internal learning is facilitated. In providing a set of guidelines for interactivity, Fenrich (1997) suggests the following set of options:
To provide a context for meaningful learning, Hannafin (1989) identified a set of five interactive functions (navigation, query, verification, elaboration, procedural control) and suggested a set of engaging activities to support these functions - fault free questions, queries, real time responding, notetaking, predicting/hypothesising, hypertext and cooperative dialogue. Although published over a decade ago the conclusions provide a useful guide for understanding interactivity:
It is no longer adequate to simply describe interactions in terms of either input technology employed or the physical characteristics of the responses made. ... We need a richer understanding of the psychological requirements associated with instructional tasks and responses, and a sense for how to extend design science beyond the methods that have evolved through the years. (Hannafin, 1989:178)Interactivity and meaningful learning has also been considered in terms of the schema model of human memory, where information is perceived as being stored in a web of interconnected nodes. "The strength of knowledge relies not simply on the number of nodes that exist, but more on the quality and number of interconnections between the nodes" Parrish (1996:2). Interactivity that encourages deeper cognitive processing (Craik & Lockhart, 1972) will potentially lead to these interconnections being built.
When considered in relation to computer enhanced learning, distance is an issue. While learner and computer are in close physical proximity, the extent to which there is distance (or lack of communication) between teacher, content and learner will diminish the effectiveness of the interactions. The extent to which communication or conversation between learner and designer can be integrated into a computer based medium has been analysed by Laurillard (1993), in which a conversational framework is used to identify the teacher-learner relationships. Enabling these concepts in the computer based medium is the challenge addressed within this paper.
Storytelling and narrative lie at the heart of all successful communication. Crude, explicit, button pushing interaction breaks the spell of engagement and makes it hard to present complex information that unfolds in careful sequence.In this scenario the difference between the overt interactions are explicitly compared with the potential of narrative. The challenge confronting educational technology developers is the production of computer based environments that engage the learner in effective instructional communication without the interactivity interfering with the overall process. Identifying the concepts of storytelling and narrative as critical determinants of communication have been shown to provide a context to enable the potential of interactive learning environments.
Since interactive interfaces ought to foster ... coordination between improvisation and planning we need to discover better theories of what is involved in the dynamic control of inquiry, line of thought, and action more generally. We need to discover more open ended models of coherence and narrative structure. Kirsh (1997:81)Interactivity is portrayed as the crucial element of the new technology and yet recent research has demonstrated that there is still much to understand about the ways in which the interactive process facilities access to technology, especially in the context of computer based learning applications. Plowman (1996a:102-103) states,
disruption of the narrative is strongest at the foci of interactivity ... (which) should be considered in terms of how they can be integrated into the overall narrative and how they can be used as a way of stimulating interest in the unfolding narrative ... by considering the interrelationship of narrative, linearity and interactivity and their design implications we can help learners to make sense of interactive multimedia.The extent to which the interactions implemented are disruptive or constructive is an area that has received little attention to date but one that may provide some new guidelines for designers. As a concept, narrative can be viewed as a linear storyline or in terms of how the story is told, the way it is received, what meanings it can have and the specific social, cultural, gendered and technological context in which it is told (Plowman, 1996a; Humphreys, 1997b). But in what ways might narrative assist meaning, reduce the impact of interactive interference and provide the necessary framework to promote learning amongst diverse groups of learners? Plowman (1996a:92) suggests that:
Narrative coherence is identified here with a lack of redundancy and a fixed sequence. Interactive multimedia (IMM) programmes challenge these traditional definitions of narrative because it can be suspended or altered at discrete decision points, the foci of interactivity, and a rearrangement of discrete elements gives rise to new text and new meanings. While the concepts of wholeness, unity and coherence of meanings are not fashionable in a post-modern world, in educational multimedia... the notion of multiple interpretations has different implications, particularly for comprehension and cognition.While "narrative isn't just a shaping device: it helps us think, remember, communicate, and make sense of ourselves and the world" (Plowman, 1996a:3), when considered in terms of interactive environments, its perceived advantages are through enhancing comprehension and understanding:
Narrative structure is fundamental to comprehension to the extent that when it is clearly absent from certain forms of multimedia (it) can seriously undermine comprehension of the material. (Laurillard, 1998:231).
Framework which accommodates the audience or user into the process of engagement with interactive media in ways that narrative theory finds difficult... Interactivity produces for the user of media a different relationship to story. This shift in relationship may be able to be framed as a shift from narrative, as an experience of recounting a story, to play, as an experience of enacting a story. Humpherys (1997:9,11)A focus on either narrative or play as structures to enhance engagement implies that the interactivity provided must be integrated to enable reinforcement of the specific learning objectives and to maintain the user's participation in the story. It is our challenge therefore to develop applications that minimise the potential for interactive interference. By considering the concept of interactivity, narrative and play in association with the links between the designer and learner, the following section presents a model to potentially enhance the communication between learner and designer within computer based environments.
The association of education with theatre is by no means novel:
As we develop as persons, we develop a sophistication and sensitivity to what is the "proper" role behaviour for various groups we must meet ... We are in a sense able to predict the consequences of various behaviour alternatives on others without actually performing them, and can select the best role and performance ... This process is seen as "dramatic rehearsal" ... and is as complex as the relationship of actor and audience on stage. Hodgkinson (1967:3)In the context of education and social change, these concepts of performance, roles, identity and cues provide a focus for the learning environment. "As on stage, we are constantly sending out signals to those around us telling them how we wish to behave ... education at all levels is constantly faced with the problem of correcting misunderstood or unintentional cues" (Hodgkinson, 1967:22). To what extent therefore do computer based learning applications provide learners with a set of confusing cues, and in what way are learners allowed to play a role when working with educational technology? If, as Hodgkinson (1967) argues, being unaware of role playing can damage educational goals, it may be that the concept of roles, cues, theatre and performance hold clues as to making computer based learning work better.
Laurel (1990), who proposed the computer as theatre, also identifies the importance of human agency in human-computer interaction. Using this analogy, it is possible to extend the narrative and play concept to that of theatre and the role of the learner from observer or participant to actor:
By explicitly casting the language learner as actor (or other), a more playful and reflexive context for taking performative risks becomes possible. At the same time, the learner is pressed to assume responsibility for communicative acts that involve skill building at multiple levels of performance (phonological, kinetic, pragmatic), and that include but go beyond propositional knowledge. (Quinn, 1997:1).If the learner is to become and actor, then the structure of the application can be perceived as a performance. Trognazzini (1999) identifies magicians and illusionists as performers and that, in the same way that their act must be believable, so must interactive software have the same elements of acceptance:
I propose that there is a "threshold of believability," a point at which careful design and meticulous attention to detail have been sufficient to arouse in the spectator or user a belief that the illusion is real. The exact point will vary by person and even by mood, so we must exceed it sufficiently to ensure believability.If the learner believes the illusion created by the educational environment then the interactions will become integral to that illusion rather than as external controls to an environment being observed. Playing a role, being an actor in the learning process is not only about making choices but becoming part of the narrative, story or performance.
To date, many computer based learning resources have placed the learner as observer (passive or active) in much the same way as members of an audience at a performance. However, this separation of actor and audience provides an essentially uni-directional communication - from stage to audience. If the learner were to take a position on stage, what might that mean for computer based learning and how might it be implemented?
Designers might extend the concepts proposed by Hannafin & Peck (1988) to create scenarios in which the learner has an opportunity to participate. This would involve the learner being asked how familiar they are with the application and the extent to which they would like orientation to the application. The tour should allow the user to ask questions for clarification, in much the same way that an actor and director peruse the script and work through a series of rehearsals. Once comfortable with the location and prepared for "opening night", learners need to be made familiar with the controls (the stage, props and other actors) - not in their use but in their purpose - and the relevance of their appearance on the display (location on the stage). By using a narrative or story to define the performance in which the learner is participating, a logical and meaningful series of interactions can be employed.
An argument against such design structures is that they are too expensive or too difficult to implement, but this is not necessarily the case. If computer based learning resources continue to be used then it is important that they be effective. To date this has not been achieved consistently, so if more effective resource can be structured then the initial costs will be outweighed by the benefits. Similarly, as technology is developing so rapidly the creation of what now appear to be complex environments will become components of the development software.
The integration of the learner into the overall process may provide an environment in which the communication is focused on learner and teacher (designer) rather than learner and computer (content). Laurillard (1993) proposed the discursive, adaptive, interactive and reflective elements of education media in relation to effective teacher-learner communications. Continuing to develop the way in which people work with computers in learning contexts will provide the means by which these elements will continue to be successfully integrated into computer based environments. Conceptualising the learner as actor may provide a means to achieve this.
One of the first mottos I heard when beginning my career in this field was "you're only limited by your imagination". My vision is one of a learner integrated, engaged and achieving in a computer based environment - imagining a learner on stage, playing a critical role in the narrative is how that vision might be realised. The success of computer based learning will be through interactivity as a manifestation of communication between designer and learner. If the designer can develop their ideas into a performance into which the learner is actor and interactivity the stage, then the illusion, magic and engagement so eagerly sought after might well be achieved.
