Enhancing academic performance in distance education with concept mapping and inserted uestions

This research was designed to investigate the relative strength of two instructional strategies — inserted questions and concept mapping — for enhancing the academic performance of distance learners. The sample for this field experiment comprised one hundred and forty‐one nursing students enrolled in a 20‐week distance education course. A significant difference was found in favour of subjects who completed at least 11 of 12 concept mapping exercises. These subjects also indicated a preference for visual and graphic learning techniques. Inserted questions with explicit corrective feedback outperformed questions without such feedback.     

Interactivity and interactive functions in web-based learning systems: a technical framework for designers

The concept of interactivity and its implications for Web-based learning system design is re-examined. The author reviews the literature on the interactivity concept from the perspectives of communication, computer-assisted instruction, distance education, and interactive dimensions and functions for Web systems. A proposal is then made for a technical framework for including such dimensions and functions in Web-based learning systems. To enhance the framework's ease-of-use and overall effectiveness, each interactive function was submitted to two panels of experts for assessment and evaluation in terms of instructional necessity and programming difficulty. A discussion of the panels’ feedback and the potential for future research concludes the article.     

Preparing students for future learning with Teachable Agents

One valuable goal of instructional technologies in K-12 education is to prepare students for future learning. Two classroom studies examined whether Teachable Agents (TA) achieves this goal. TA is an instructional technology that draws on the social metaphor of teaching a computer agent to help students learn. Students teach their agent by creating concept maps. Artificial intelligence enables TA to use the concept maps to answer questions, thereby providing interactivity, a model of thinking, and feedback. Elementary schoolchildren learning science with TA exhibited “added-value” learning that did not adversely affect the “basic-value” they gained from their regular curriculum, despite trade-offs in instructional time. Moreover, TA prepared students to learn new science content from their regular lessons, even when they were no longer using the software.     

In support of a functional definition of interaction

Abstract

A common theme in the distance education literature is that delivery technologies with the potential for real‐time interactivity will improve both the image and practice of distance education. Although there appears to be a growing acceptance of a causal relationship between system interactivity and instructional interaction, neither concept has been clearly or functionally defined. This article discusses several systems models and relates them to the contexts of instructional delivery, instructional design, instructional theory, and learning theory in an attempt to establish conceptual parameters for the function of interaction.     

Questioning the Role of Technology in Higher Education: Why is this the Road Less Traveled?

This paper analyzes four issues that influence teaching and learning in college classrooms. These issues include the idea that using instructional technology in higher education should not be questioned; relationship between the corporate community and higher education; and effectiveness of distance learning as an instructional delivery system. The fourth issue, and possibly the most important, is developing a rich and deep understanding for the meaning of computer instructional technology, its relationship to teaching and learning, and the role it plays in shaping the context of what it means to be “educated.” A critical perspective, supported by the literature, is used to analyze these issues in the context of the college classroom. The paper closes with 20 questions intended to generate thinking and discussion about making thoughtful, informed and contextualized instructional decisions.

Effects of In-video Questions and Feedback on Learning Performance

The eye-tracking technology was used in this study to investigate the effects of embedded questions and feedback in instructional videos on learning performance and attention allocation and whether an expertise reversal effect existed. The experiment involved 49 learners with high-level prior knowledge and 45 ones with low-level prior knowledge from a university. Meanwhile, they learned instructional videos with no embedded feedback, embedded questions without feedback and embedded questions with feedback. Findings from the experiment showed that the instructional videos with embedded questions but without feedback not only improved the participants’ attention but also enhanced their learning performance. Furthermore, there was an expertise reversal effect on the learning performance whereby instructional videos with embedded questions but without feedback improved the learning performance of learners with low-level prior knowledge, but not those with high-level prior knowledge.     

In‐Text Questions: A Note on an Experiment in Instructional Design

The use of instructional design is increasingly being discussed in the distance education and higher education literature. This paper reports an experiment in which self study questions are inserted in the text of lecture note material for external students. An evaluation revealed that students who received notes with in‐text questions were no different from those who received the standard lecture notes as judged by both performance and attitudinal criteria. Possible reasons for the perverse findings are given and it is concluded that professional instructional design assistance would be of value to subject matter experts.     

Teaching‐learning specialists' conceptions of their role in the design of distance learning packages

A phenomenographic study of the conceptions that teaching‐learning specialists working in distance education in Australian universities hold of their role in contributing to the development of distance education packages is described. The study identified eight conceptions labelled instructional editor, educational process consultant, instructional process consultant, transformer, critical reviewer (surrogate student), joint venturer, distance education development facilitator, and staff developer. The conception, distance education developer, differed from the other conceptions insofar as it reflected a greater concern with organisational as compared with teaching‐learning issues. The remaining conceptions were able to be distinguished, according to whether they indicated a macro level (structural) perspective or a micro level (process) perspective. The former included the educational process consultant and staff developer conceptions. The latter were able to be further distinguished according to whether they indicated an understanding of the learning package as dialogic text (critical reviewer) or as an instructional medium (instructional process consultant, instructional editor, joint venturer, and transformer). Finally, the four conceptions which reflected an understanding of the learning package as an instructional medium could be distinguished according to the way in which the teaching‐learning specialist saw his or her relationship with the subject specialist in terms of power.     

Learning efficiency of two ICT-based instructional strategies in Greek sheep farmers

Purpose: The objective of the present study was to compare the learning efficiency of two information and communications technology (ICT)-based instructional strategies (multimedia presentation (MP) and concept mapping) in a sample (n?=?187) of Greek sheep farmers operating mainly in Western Greece. Design/methodology/approach: In total, 15 instructional sessions have taken place. The knowledge assessment of the farmers, before and after the instructional interventions, was based on answers given to five questions of graded difficulty and the SOLO (Structure of Observed Learning Outcomes) taxonomy. Findings: The two instructional strategies showed comparable learning outcomes. Furthermore, prior participation to training sessions as well as the participants’ advanced education level enhanced the learning outcome. Practical implications: Simple applications of ICTs such as MPs and concept maps can be exploited in sheep farmers’ training. Special attention has to be paid to the content and the context of the digital learning material. Originality/value: The study contributes to the lack of evidence regarding the assessment of learning outcomes of instructional strategies assisted by digital learning environments in livestock farmers.     

Knowledge engineering: An alternative approach to curriculum design for science education at a distance

Most of the curriculum design models within the technical-scientific approach utilise the rational and sequential process of designing and inter-relating the various elements of the design process. While this procedure may be efficient and adequate for conventional education in which the designers are professional science educators, there is doubt if it satisfies the particular needs of distance education. The experience accumulated through a multi-disciplinary team approach to distance learning courseware development for higher education at the University of Southern Queensland Distance Education Centre motivated this study which primarily focused on a search for an alternative approach to curriculum development with a more satisfactory functional value. Using selected units in Engineering as a focus, an experiment was designed in which a variant of the classical Wheeler model was used. This paper reports the results of this experiment. The implications for contemporary curriculum development initiatives in science especially within distance education settings are pointed out. Specializations: science education, learning strategies, curriculum development, instructional design, research and development in distance education. Specializations: Cognitive Science, curriculum development, instructional design, expert systems, research and development in distance education.

Defining the Learner Feedback Experience

A surge in the proliferation of educational technology tools and models means that postsecondary learners and instructional designers have more options than ever before. Selecting the most appropriate tool for a given learner-centered instructional situation is challenging. The construct of feedback is central to an effective learner-centered instructional design. The present summary of the research on feedback in learner-centered instructional design models provides a rationale for the value of defining the dimensions of a high-quality learner feedback experience. Six dimensions of feedback are proposed; namely, timeliness, frequency, distribution, source, individualization, and content. Key questions posed include whether an analysis of the learner’s feedback experience is a better proxy for measuring the quality in postsecondary online learning than grades, satisfaction, or regular and substantive contact.     

Network Applications for Group-Based Learning: Is More Better?

Group-based learning is being introduced into many settings in higher education. Is this a sustainable development with respect to the resources required? Under what conditions can group-based learning be applied successfully in distance education and in increasingly flexible campus-based learning? Can networked support facilitate and enrich courses where group-based learning is applied? These questions formed the basis of the motivation for the research project whose main results are presented here. The goals set for the research were the identification of problems associated with the planning, operationalisation, and monitoring of group tasks in group-based learning in higher education, and the identification of networked support options which, in combination with appropriate instructional decisions, have the potential to remedy these problems. The solutions identified were tested in the context of three case studies.

Detrimental effects of immediate explanation feedback

Adjunct questions are a common means to foster learning from instructional explanations. As the benefit of adjunct questions is mitigated if learner performance on them is low, it is also common to provide feedback as an add-on if learners fail to correctly respond to them. However, if adjunct questions are highly demanding, feedback might not only beneficially affect learning because it helps learners revise their comprehension difficulties; at the same time, it could also detrimentally affect learning by causing learners to invest less time in responding to subsequent adjunct questions, which lowers learner performance on these questions. This, in turn, could reduce learning outcomes. To address these potential detrimental effects of feedback, we experimentally varied whether N?=?59 students received immediate feedback after they responded to highly demanding adjunct questions. We found that the feedback did indeed have detrimental effects: At least for the learners who perceived the task of responding to the adjunct questions as highly demanding, the feedback decreased both the time the learners invested in responding to the adjunct questions and their performance on them. This detrimental effect on the performance on the adjunct questions, in turn, entailed a detrimental effect on learning outcomes. We conclude that immediate feedback is not necessarily a beneficial add-on to adjunct questions in all situations.     

Validated Competencies for Distance Teaching

The International Board of Standards for Training, Performance and Instruction (IBSTPI) provides a methodology for drafting and validating teaching competencies. This study applied the IBSTPI methodology to identify and validate distance education (DE) instructor competencies. The research team's review of DE literature in the past 10 years resulted in a list of 20 competencies. The list was reviewed by 18 distance learning professionals as subject matter experts (SMEs). The SMEs' feedback and comments along with the performance statements developed for the competencies were analyzed which resulted in 54 task statements describing the instructional activities of a DE instructor. These tasks were then rated by 148 instructors in terms of importance, frequency of performance, and the perception of relative time spent on each task. The task analysis resulted in a list of 17 most frequently performed tasks that we linked back to the corresponding original competencies. Analysis of these data pointed out the significant characteristics of teaching from a distance including interaction with learners and technological and logistical requirements. This article presents the methodology and findings of this study and discusses their implications for recruitment, selection, and training of DE instructors.     

Troubled times: the role of instructional design in a modern dual-mode university?

Reduced higher education funding and other austerity measures imposed by governments and institutions have resulted in cascading cuts in resources for programme design, delivery and revision. The instructional design function is often the first casualty of these cuts in many universities. This paper considers the roles and functions of instructional design, illuminates the differences in instructional design functions in on-site learning and in distance learning, and examines the broadening of skills and responsibilities encompassed in instructional design, especially in dual-mode institutions. Two case studies, illustrating different levels of instructional design in course development for distance learning in a dual-mode institution, lead to reflections on the value of instructional design in the current and future higher education landscape.     

The effect of reciprocal teaching and programmed instruction on learning outcome in computer science education

Answers to the questions of which instructional methods are suitable for school, what instructional methods should be applied in teaching individual subjects and how instructional methods support the act of learning represent challenges to general education and education in individual subjects. This study focuses on the empirical examination of learning outcome with respect to two instructional methods: programmed instruction and reciprocal teaching. An SPF-2 × 2•2 design is used to control instructional method, time and class context. Learning outcome on search queries is assessed with reference to multi-choice test items. The empirical findings show that learning with programmed instruction performs better than reciprocal teaching.     

A distributed collaborative science learning laboratory on the internet

Abstract

A Distributed Collaborative Science Learning Laboratory (DCSLL) was designed, prototyped, and pilot‐tested as the “Electrical Circuit Simulator.” This laboratory was part of a module on electricity within an introductory distance course for postsecondary students on the scientific method. The concept of DCSLL emerged from work in distance education and new technologies, cooperative/collaborative learning, and science education. Instructional design principles derived from these areas are presented, and their implementation in the DCSLL is described, followed by results from the pilot test. Analysis of the results led to the articulation of six instructional design guidelines, identified as being key to the development of such learning environments.
