Audio-based versus text-based asynchronous online discussion: two case studies

The main objective of this paper is to examine the use of audio- versus text-based asynchronous online discussions. We report two case studies conducted within the context of semester-long teacher education courses at an Asian Pacific university. Forty-one graduate students participated in Study I. After the online discussions (both audio-based as well as text-based) had ended, qualitative data via student reflections were collected. Results revealed that audio-based discussions have six distinct perceived affordances compared to text-based ones. Interestingly, despite the reported affordances, more than half of the students reported that they preferred to use a text-based discussion if given a choice. The main reasons for their preference were explored. In Study II, 42 undergraduate students took part. Similar to Study I, participants in Study II also indicated that they felt more comfortable using a text-based discussion. The reasons for their preference were also discussed. Directions for future research are proposed.     

Research in online and blended learning in the business disciplines: Key findings and possible future directions

In this literature review, we examine and assess the state of research of online and blended learning in the business disciplines with the intent of assessing the state of the field and identifying opportunities for meaningful future research. We review research from business disciplines such as Accounting, Economics, Finance, Information Systems (IS), Management, Marketing, and Operations/Supply Chain Management. We found that the volume and quality of research in online and blended business education has increased dramatically during the past decade. However, the rate of progress is somewhat uneven across disciplines. IS, Management, and multi-disciplinary studies have the highest volumes of research activity, with markedly less activity in Finance and Economics. Furthermore, scholars of online and blended business education predominantly publish in learning and education journals of the business disciplines rather than also publishing in journals that focus on technology-mediated learning, thereby missing an opportunity to inform scholars in other disciplines about their work. The most common research streams across disciplines were outcome comparison studies with classroom-based learning and studies examining potential predictors of course outcomes. Results from the comparison studies suggest generally that online courses are at least comparable to classroom-based courses in achieving desired learning outcomes, while there is divergence in findings of comparisons of other course aspects. Collectively, the range of untested conceptual frameworks, the lack of discipline-specific theories, and the relative absence of a critical mass of researchers focused on the topic suggest ample opportunities for business scholars seeking to enter this research community.     

Recognising and promoting collaboration in an online asynchronous discussion

This paper reports on a study involving the identification and measurement of collaboration in an online asynchronous discussion (OAD). A conceptual framework served for the development of a model which conceptualises collaboration on a continuum of processes that move from social presence to production of an artefact. From this model, a preliminary instrument with six processes was developed. Through application of the instrument to an OAD, the instrument was further developed with indicators added for each process. Use of the instrument to analyse an OAD showed that it is effective for gaining insight into collaborative processes in which discussants in an OAD do or do not engage. Use of the instrument in other contexts would test and potentially strengthen its reliability and provide further insight into the collaborative processes in which individuals engage in OADs. Analysis of an OAD using the instrument revealed that participants engaged primarily in processes related to social presence and articulating individual perspectives, and did not reach a stage of sharing goals and producing shared artefacts. The results suggest that the higher‐level processes related to collaboration in an OAD may need to be more explicitly and effectively promoted in order to counteract a tendency on the part of participants to remain at the level of individual rather than group or collaborative effort.     

Project-based learning and student knowledge construction during asynchronous online discussion

Project-based learning engages students in problem solving through artefact design. However, previous studies of online project-based learning have focused primarily on the dynamics of online collaboration; students' knowledge construction throughout this process has not been examined thoroughly. This case study analyzed the relationship between students' levels of knowledge construction during asynchronous online discussions with respect to engagement in project-based learning. Graduate students' online postings in a course that comprised both project-based and non-project learning activities were coded and counted for knowledge construction, teaching, and social interaction moves using computer-mediated discourse analysis. Chi-square analyses found that the instructor's teaching discourse remained fairly consistent during project-based and non-project learning. Despite this, students' online discussions during project-based learning were characterized by more advanced levels of knowledge construction, where ideas were rationalized and integrated into plausible solutions. In contrast, students' online postings outside project-based learning rarely moved beyond the lower levels of information sharing and idea exploration. Based on these results, guidelines for designing and facilitating online project-based learning are presented and discussed.     

Designing and implementing peer formative feedback within online learning environments

With increasing need to achieve appropriate balance between learning support and self-regulation within the context of online learning, formative feedback has been identified as a viable means to achieve meaningful engagement. Specifically, this study sought to establish how peer–peer formative feedback was facilitated in an online course and to what extent this engaged students in meaningful learning experiences. This case study entailed an in-depth investigation into the design and implementation of an online course in a New Zealand university. The studied course was part of a postgraduate programme in continuing (in-service) teacher education. The study adopted a case study methodology with a bias on qualitative techniques. Online observations, analysis of the archived course discourse and interviews were utilised as sources of data. The data from multiple sources were subsequently triangulated to corroborate the evidence. The findings indicate that peer formative feedback promoted active learners’ participation and meaningful engagement. The findings further showed that opportunities for dialogic peer formative feedback promoted learning support and self-regulation.     

Student contribution in asynchronous online discussion: a review of the research and empirical exploration

The increasingly prevalent use of Internet in schools and homes has resulted in asynchronous online discussion becoming an increasingly common means to facilitate dialogue between instructors and students, as well as students and students beyond the boundaries of their physical classrooms. This article is organized into two main sections. In the first section, we review 50 empirical studies in order to identify the factors leading to limited student contribution. Limited student contribution is defined as students making few or no postings, or students exhibiting surface-level thinking or low-level knowledge construction in online discussions. We then identify the various empirically based guidelines to address the factors. In the second section, we discuss three potential guideline dilemmas that educators may encounter: (a) use of grades, (b) use of number of posting guideline, and (c) instructor-facilitation. These are guidelines where previous empirical research shows mixed results when they are implemented. Acknowledging the dilemmas is essential for educators and researchers to make informed decisions about the discussion guidelines they are considering implementing. Finally, we report two exploratory case studies on student-facilitation that we conducted. Using students as facilitators may be an alternative solution to educators who wish to avoid the instructor-facilitation guideline dilemma.     

Designing asynchronous online fermentation science materials including using a home fermented foods project to engage online learners

The number of online courses offered by universities in America continues to increase. Due to limited direct interactions with students, these courses can struggle to promote student engagement. Food science is uniquely situated for implementation of hands‐on project‐based learning opportunities since basic experiments can be performed in a kitchen with minimal supplies and equipment. The purpose of this teaching and learning tip is to share materials designed for an asynchronous online course, instructional fermentation vignettes, and the Home Fermented Foods Project assignment, which tasks students with creating two fermented foods with two accompanying documents explaining the science of each employed steps. Students are engaged with the projects while connecting the lecture material to familiar products that they create such as sauerkraut, yogurt, and bread. Overall, based on student evaluations and our interactions with the students, our implementation of this project has been positive. Downloadable handouts containing assignment details are available as Supporting Information.     

Participation in asynchronous online discussion forums does improve student learning of gross anatomy

Asynchronous online discussion forums are common in blended learning models and are popular with students. A previous report has suggested that participation in these forums may assist student learning in a gross anatomy subject but it was unclear as to whether more academically able students post more often or whether participation led to improved learning outcomes. This study used a path model to analyze the contribution of forum participation, previous academic ability, and student campus of enrolment to final marks in a multicampus gross anatomy course for physiotherapy students. The course has a substantial online learning management system (LMS) that incorporates asynchronous forums as a learning tool, particularly to answer learning objectives. Students were encouraged to post new threads and answer queries in threads started by others. The forums were moderated weekly by staff. Discussion forums were the most used feature of the LMS site with 31,920 hits. Forty‐eight percent of the students posted at least once with 186 threads initiated by students and a total of 608 posts. The total number of posts made a significant direct contribution to final mark (P = 0.008) as did previous academic ability (P = 0.002). Although campus did not contribute to final mark, there was a trend for students at the campus where the course coordinator was situated to post more often than those at the other campus (P = 0.073). These results indicate that asynchronous online discussion forums can be an effective tool for improving student learning outcomes as evidenced by final marks in gross anatomy teaching.

Evaluating the quality of interaction in asynchronous discussion forums in fully online courses

Fully online courses are becoming progressively more popular because of their “anytime anywhere” learning flexibility. One of the ways students interact with each other and with the instructors within fully online learning environments is via asynchronous discussion forums. However, student engagement in online discussion forums does not always take place automatically and there is a lack of clarity about the ideal role of the instructors in them. In this article, we report on our research on the quality of discussion in fully online courses through analysis of discussion forum activities. We have conducted our research on two large fully online subjects for computing students over two consecutive semesters and used a grounded theoretic approach for data analysis. Our results reveal what students and instructors consider as quality interaction in fully online courses. We also propose two frameworks based on our findings that can be used to ensure effective online interaction.     

Student outcomes associated with use of asynchronous online discussion forums in gross anatomy teaching

Asynchronous online discussion forums are increasingly common in blended learning environments but the relationship to student learning outcomes has not been reported for anatomy teaching. Forums were monitored in two multicampus anatomy courses; an introductory first year course and a second year physiotherapy‐specific course. The forums are structured with a separate site for each course module and moderated weekly by staff. Students are encouraged to post to new threads (initial post) and answer queries in threads started by others (reply post). Analysis of forums was conducted separately for each course and included overall activity (posts and views) for a full semester and a detailed analysis for one week in the middle of semester. Students were classified as zero, moderate, or high contributors to the forums based on the number of posts. Final mark for the course was related to level of forum contribution using nonparametric tests. Forum threads were characterized as task‐focused, administrative, or other. A higher proportion of second year (36%) than first‐year (17%) students posted on the forums and the postings were more likely to be task‐focused and student initiated. Second‐year students that posted frequently to the forum gained a higher final mark for the course than those that did not post or only posted a moderate number of times (P < 0.01). This relationship was not evident for first‐year students who had a much higher proportion of administrative threads. Forums in anatomy courses can be powerful learning tools encouraging deeper learning and improved learning outcomes. Anat Sci Educ 6: 101–106. © 2012 American Association of Anatomists.     

Higher-level knowledge construction in asynchronous online discussions: an analysis of group size, duration of online discussion, and student facilitation techniques

This study is concerned with the challenge of understanding what factors may influence students’ higher level knowledge construction. We defined higher level knowledge construction occurrences as the sum of the number of phases II to V measured using Gunawardena et al.’s (J Educ Comput Res 17(4):397–431, 1997) interaction analysis model. This paper is organized into two studies. In the first study, we examined the relationship between the frequency of higher level knowledge construction occurrences and group size, as well as the duration of the online discussion. Data were collected through online observations of 40 discussion forums. We found a significant positive relationship between group size and the frequency of higher level knowledge construction occurrences. However, there was no correlation between the duration of the online discussion and the frequency of such occurrences. In the second study, we examined the types of student facilitation techniques used. A further analysis of the data was conducted—of the 40 forums, 14 forums with higher incident rate of higher level knowledge construction occurrences were identified. Fourteen less frequent forums were then randomly chosen from the remaining forums. We found significant differences in the frequency of four student facilitation techniques employed between the more frequent group and the less frequent one. The results of this study suggest that using these four techniques more frequently may promote knowledge construction in asynchronous online discussions.     

History of education research in Australia: some current trends and possible directions for the future

The history of education as a distinct field has been the focus of study, research and writing in Australia for over a century. It achieved maturity with the establishment of the Australian and New Zealand History of Education Society in 1970 and the subsequent establishment of the Society’s journal, History of Education Review. Since then, Australian scholars have been major contributors to the field, with certain individuals being key players on the world stage. Taking cognisance of this background, this paper considers current trends and directions for the future. It does so by focusing on three areas: scholarship on topics relating specifically to Australia; the use of new methods; and Australian-based scholars contributing to scholarship where the focus is beyond their immediate geographical boundaries.     

Rubrics for designing and evaluating online asynchronous discussions

The purpose of the study reported on in this paper was to identify performance criteria and ratings in rubrics designed for the evaluation of learning in online asynchronous discussions (OADs) in post-secondary contexts. We analysed rubrics collected from Internet sources. Using purposive sampling, we reached saturation with the selection of 50 rubrics. Using keyword analysis and subsequent grouping of keywords into categories, we identified 153 performance criteria in 19 categories and 831 ratings in 40 categories. We subsequently identified four core categories as follows: cognitive (44.0%), mechanical (19.0%), procedural/managerial (18.29%) and interactive (17.17%). Another 1.52% of ratings and performance criteria were labelled vague and not assigned to any core category.     

Microanalytic case studies of individual participation patterns in an asynchronous online discussion in an undergraduate blended course

This study presents three case studies of students' participation patterns in an online discussion to address the gap in our current understanding of how individuals experience asynchronous learning environments. Cases were constructed via microanalysis of log-file data, post contents, and the evolving discussion structure. The first student was Thorough, reading all the posts in the forum in sequence, revisiting different posts multiple times, and creating posts outside of the discussion tool. The second student was Self-Monitoring, revisiting his own posts multiple times, checking the discussion frequently for replies, and replying to or editing his posts in response. Finally, the third student was Independent, using the forum as a tool for her own individual reflection. The behaviors found for these cases are aligned with a theoretical taxonomy for participation proposed by Knowlton (2005). The value and limitations of the microanalytic case study approach are discussed, and implications for research and practice are suggested.     

Interaction and cognitive engagement: An analysis of four asynchronous online discussions

Online discussion plays a unique role in face-to-face and distance teaching and learning. Interaction and student cognitive engagement during the online discussion are critical for constructing new understanding and knowledge. This article analyzes types of interaction that occur during online discussions, examines levels of student cognitive engagement in each discussion, and explores their effects on and implications for learning and teaching in higher education. By combining methods of social network analysis with qualitative content analysis, the article explores new methodologies for analyzing participation, interaction, and learning that take place online, and suggests areas for research in learning and teaching online.
