The effects of different instructor facilitation approaches on students’ interactions during asynchronous online discussions

This study compared the impact of three different facilitation approaches on elementary teacher candidates’ interactions in an asynchronous discussion board as well as their satisfaction with an online educational technology course. These participants were enrolled in three different sections of the same online course. In the first section (Group 1), the instructor responded to each student’s initial message regarding the discussion question and then required students to respond to at least two of their classmates’ postings. In the second section (Group 2), the instructor responded to each student’s initial message to the discussion question, but did not require students to respond to other classmates’ postings. Instead, it was the student’s voluntary choice. In the third group (Group 3), the instructor did not respond to each student’s initial message on the discussion question, but required students to respond to at least two classmates’ postings. Data were analyzed both quantitatively and qualitatively, by using ANOVA, social networking analysis (SNA) and content analysis. The results indicated that in Group 2, voluntary interactions among students rarely occurred, resulting in the instructor primarily providing feedback to the students, with a low number of cues for social presence. In comparing Groups 1 and 3, when students were required to respond to one another, too much instructor intervention did not lead to more interactions among the students. Rather, when the instructor’s intervention was minimal, students tended to more freely express their thoughts and opinions, with a large number of cues for social presence. However, more interactions among students, occurring in a required setting, may not have correlated with student satisfaction with the online course ratings and the instructors’ ratings.     

EFL learners’ use of online reading strategies and comprehension of texts: An exploratory study

This study investigated EFL learners’ online reading strategies and the effects of strategy use on comprehension. To fulfill the purposes of this study, a Web-based reading program, English Reading Online, was created. Thirty applied English majors, divided into a high group and a low group based on their proficiency levels, were asked to read four authentic online texts; two were appropriate to the students’ level of proficiency, and two were more difficult. Results from data analysis showed that the use of support strategies dominated the strategy use and contributed to most of the comprehension gains, but an exclusive dependence on support strategies did not successfully predict the increase in scores on main ideas and details when the students were reading more challenging texts. On the whole, the use of global strategies significantly contributed to better comprehension, especially for low proficiency students.     

Promoting and scaffolding argumentation through reflective asynchronous discussions

The purpose of this quasi-experimental study was to explore the impact of asynchronous discussion on the quality and complexity of college students’ arguments. Three different cohorts of students registered in a physical science course in 2009 Fall, 2010 Spring, and 2010 Fall semesters were briefly supported with scaffolding in class and then involved in argumentation about socio-scientific issues as take-home assignments. Each cohort was divided into an asynchronous online communication group and a paper–pencil group. The findings showed that very few students’ arguments from either group were rated low in quality levels of 1 or 2 on a five-scale level. Additional comparisons revealed that the asynchronous online communication group students slightly outperformed their counterparts in terms of mean quality level of arguments (effect sizes ranged from 0.25 to 0.35) and the frequency of rebuttals. The major finding is that after only one hour of scaffolding followed by the opportunity to practice argumentation at home, students’ argumentation skills were slightly better developed through reflective asynchronous online discussions about socio-scientific issues than through paper-pencil practice.     

Students' perceptions of instructors' roles in blended and online learning environments: A comparative study

This study develops an instrument—the Online Instructor Role and Behavior Scale (OIRBS)—and uses it to examine students' perceptions of instructors' roles in blended and online learning environments. A total sample of 750 university students participated in this study. Through a confirmatory factor analysis, the OIRBS was validated in five constructs: course designer and organizer (CDO), discussion facilitator (DF), social supporter (SS), technology facilitator (TF), and assessment designer (AD). The results show that the five factor structures remained invariant across the blended learning and online learning. Both students in blended learning environments and students in online learning environments exhibited the greatest weight in the CDO dimension, followed by the TF and DF dimensions. In addition, students in the online learning environments scored higher in the DF dimension than did those in the blended learning environments.     

When to jump in: The role of the instructor in online discussion forums

As asynchronous discussion forums become more prevalent in online and flexible-delivery modes of teaching, understanding the role that instructors play in student learning in these forums becomes an important issue. Whether the instructor chooses to lead discussions or to keep a low profile can affect student participation in surprising ways. In this study, we investigate how instructor participation rates, the timing of instructor postings (during or at the end of a forum) and nature of their postings (questions, answers or a mix of the two) relate to student participation and perception.     

Investigating ICT using problem-based learning in face-to-face and online learning environments

This article reports on the design, implementation and evaluation of a module in the MEd (Business) in the Faculty of Education at the University of Hong Kong in which an explicit problem-based learning (PBL) approach was used to investigate the challenges associated with the adoption and use of information and communication technologies (ICT) in Hong Kong secondary school classrooms. PBL influenced both the way the curriculum was developed and the process by which students (n = 18) investigated topics related to the integration of ICT in business studies classrooms. The evaluation was based on five evaluative questions dealing with the implementation of PBL, the extent to which PBL facilitated academic discourse, the extent of ‘new’ knowledge about ICT that had been created, the role of the tutor, and the online learning environment provided. The evaluation revealed that PBL provided a practical approach to investigating ICT in both face-to-face and online learning environments, leading to ‘new’ knowledge about challenges associated with the adoption and use of new technologies in various educational settings.     

The relationship between class size and online activity patterns in asynchronous computer conferencing environments

This study analyzes the relationship between class size and student online activity patterns in a series of 28 graduate level computer conferencing courses. Quantitative analyses of note production, average note size, note opening and note reading percentages found a significant positive correlation between class size and mean number of notes generated. Significant negative correlations were found between class size and average note size and between class size and percent of notes opened. Analyses of average reading speeds among large classes and small classes revealed that students in large classes were more likely to scan lengthy notes (i.e., notes that contain more than 350 words). Possible explanations for these results are discussed.     

Blended learning in higher education: Institutional adoption and implementation

Relatively little of the current research on blended learning (BL) addresses institutional adoption issues. Additional research is needed to guide institutions of higher education in strategically adopting and implementing blended learning on campus. The authors conducted a prior study in which they proposed a framework for institutional BL adoption (Graham, Woodfield, & Harrison, 2012), identifying three stages: (1) awareness/exploration, (2) adoption/early implementation, and (3) mature implementation/growth. The framework also identified key strategy, structure, and support issues universities may address at each stage. The current study applies this adoption framework to 11 U. S. institutions participating in a Next Generation Learning Challenge (NGLC) grant and attempting to transition from an awareness/exploration of BL to the adoption/early implementation phase. The study also compares U.S. institutional strategy, structure, and support approaches to BL adoption and identifies patterns and distinctions.     

Research in online learning environments: Priorities and methodologies

Due to increasing demand for education and training in the information age, online learning and teaching is becoming a necessity in our future. However, lack of research goals to understand impact of online learning environments on students is a problem in research on online learning environments. We identified four main research goals to pursue in online learning environments based on their impact on learner achievement, engagement, and retention (opposite of attrition). Those goals are (a) enhancing learner engagement & collaboration, (b) promoting effective facilitation, (c) developing assessment techniques, and (d) designing faculty development programs. Current promising work in those areas is presented. Four methods that are common in the instructional technology literature are recommended to pursue those goals. Formative research and developmental research are relevant for all four. Although appropriate for any of the goals, experimental research is a better fit for goals b and c, and activity theory is useful for goals a and b.     

The correlates of the digital divide and their impact on college student learning

By focusing on two dimensions of the digital divide—computer use and computer knowledge, this study explores four research questions: (1) What are the undergraduates doing with the computers they use at colleges? (2) How do undergraduates perform in regard to computer knowledge and skills? (3) With what is the digital divide among college students correlated? (4) What consequences does the digital divide have for student academic performance? In order to answer these research questions, a national survey was conducted. The survey investigated 3083 first-year college students of 12 4-year universities in Taiwan. A total of 2719 of them completed the questionnaires resulting in a response rate of 88.2%. In this study, the digital divide is measured in terms of computer use, which includes a variety of purposes for using computers and academic-related work as a proportion of total computer hours, and computer knowledge. Multiple regressions and a generalized ordered logit, i.e. a partial proportional odds model, are employed. The main findings include the following: (1) Undergraduates use computers not only for fulfilling their academic requirements and searching for information, but also for entertainment. On average, undergraduates spend about 19 h per week using computers, of which 5 h are academic-related. (2) Most undergraduates perform at the middle average level in terms of computer knowledge. (3) No significant differences among correlates in relating to demographic and socioeconomic family background were found in predicting the various purposes in using computers. (4) Students who are female, whose fathers and/or whose mothers are from minorities, whose fathers are blue-collar workers or unemployed, who study in the fields of the humanities and social sciences, and who enter private universities are at a disadvantage in terms of computer skills and knowledge. However, female students, students whose mothers were less educated and students who enroll in private universities are more focused computer users in terms of allocating time to academic-related work. (5) Computer knowledge and devotion to using computers for academic-related work have a moderate effect on college student learning, while the various other uses of computers do not. Of the different kinds of computer knowledge, it is the knowledge of software that helps students to learn the most.     

Effects of an online learning community on active and reflective learners’ learning performance and attitudes in a face-to-face undergraduate course

The purpose of this study was to examine the effects of an Online Learning Community (OLC) on active and reflective learners’ learning performance and attitude in a face-to-face undergraduate digital design course. 814 freshmen in an introductory digital design course were randomly assigned to one of two treatments: one offered students an OLC, which required students to discuss their assignments and readings online and participate in certain online learning activities; the other one did not offer the OLC (NC: no online learning community), but required involving students in face-to-face discussion. Individual students’ learning styles were measured using Felder and Solomon’s Index of Learning Styles Questionnaire. Results indicated that both active and reflective learners in the OLC intervention performed significantly better than those who were in the NC intervention. Results also indicated that active learners performed significantly better than reflective learners in the NC intervention; however, reflective learners performed significantly better than active learners in the OLC intervention. No significant difference between active and reflective learners’ attitudes was found. These findings indicated that OLC might be an effective means for improving both active and reflective learners’ learning performance and attitudes; however, its effects on active learners might not be as great as on reflective learners.     

Designing,visualizing, and discussing algorithms within a CS 1 studio experience: An empirical study

Within the context of an introductory CS1 unit on algorithmic problem-solving, we are exploring the pedagogical value of a novel active learning activity—the “studio experience”—that actively engages learners with algorithm visualization technology. In a studio experience, student pairs are tasked with (a) developing a solution to an algorithm design problem, (b) constructing an accompanying visualization with a storyline, and finally (c) presenting that visualization for feedback and discussion in a session modeled after an architectural “design crit.” Is a studio experience educationally valuable? What kind of technology can best support it? To explore these questions, we conducted an empirical study of two alternative CS1 studio experiences in which students used one of two different kinds of algorithm development and visualization technology: (a) a text editor coupled with art supplies, or (b) ALVIS Live!, a computer-based algorithm development and visualization tool. We found that the students who used ALVIS Live! developed algorithms with significantly fewer semantic errors. Moreover, discussions mediated by ALVIS Live! had significantly more student audience contributions, and retained a sharper focus on the specific details of algorithm behavior, leading to the collaborative identification and repair of semantic errors. In addition, discussions mediated by both ALVIS Live! and art supplies contained substantial evidence of higher order thinking. Based on our results, we make recommendations for educators interested in exploring studio-based approaches, and we propose an agenda for future research into studio-based learning in computer science education.     

The timing of online lecture slide availability and its effect on attendance, participation, and exam performance

The use of PowerPoint slides has become an almost ubiquitous practice in university classrooms, however little research has examined whether the timing of lecture slide availability to students (either before or after lecture) affects classroom behaviour or exam performance. Using a 2 (slide availability condition) × 2 (course type) between-subjects design, the present study examined lecture slide availability differences in attendance, participation, and exam performance in two courses – Research Methods and Cognitive Development – taught in both the Fall and Winter semesters. For each type of course, lecture slides were made available on the course website before lecture in one semester and after lecture in the other semester. Course material was held constant across semesters. Results showed that mean attendance was higher when slides were available before lecture, but only for the type of course that did not include attendance points as part of students’ final grades. For students who participated in class, participation was more frequent when slides were available before lecture. No significant difference in exam performance was found between lecture slide availability conditions, however. These findings suggest that making lecture slides available to students before lecture may lead to better overall attendance and participation, but exam performance is determined by more than just whether or not students have lecture slides available for their note-taking.     

Students' online interactive patterns in augmented reality-based inquiry activities

Inquiry learning has been developing for years and many countries have incorporated inquiry learning into the scope of K-12 education. Educators have indicated the importance of engaging students in knowledge-sharing activities during the inquiry learning process. In this study, a location-based augmented reality (AR) environment with a five-step guiding mechanism is developed to guide students to share knowledge in inquiry learning activities. To evaluate the effectiveness of the proposed approach in terms of promoting the knowledge sharing behaviors of students, an experiment has been conducted in an elementary school natural science course. The participants were 57 fourth-grade students from an elementary school in Northern Taiwan, divided into an experimental group of 28 students who learned with the AR-based approach and a control group of 29 students who learned with the conventional in-class mobile learning approach. The students' learning behaviors, including their movements in the real-world environment and interactions with peers, were recorded. Accordingly, the learning patterns and interactions of the two groups were analyzed via lag-sequential analysis and quantitative content analysis. It was found that, in comparison with the conventional inquiry-based mobile learning activity, the AR-based inquiry learning activity is able to engage the students in more interactions for knowledge construction. The findings of this study provide guidance for helping teachers develop effective strategies and learning designs for conducting inquiry-based learning activities.     

The relative effects of positive interdependence and group processing on student achievement and attitude in online cooperative learning

This study investigated the effects of positive interdependence and group processing on student achievement and attitude in online learning. Students in three university courses received initial instruction about teamwork skills and cooperative learning and were randomly assigned to one of three treatment groups in each course. The “positive interdependence” and the “group processing” groups received subsequent associated skills training. The “no structure” control group received no additional training. Following the treatment, the “positive interdependence” groups had significantly higher achievement than the “group processing” or the “no structure” groups. There was no significant difference among any of the three groups on student attitude.     

Attitudes of college students enrolled in 2-year health care programs towards online learning

Colleges offering 2-year diplomas to high-school graduates were among the forefront leaders in online learning however studies illustrating appropriate course construction for such student populations are scarce. Pharmacy Math (MATH16532) is a core course for students enrolled in the Practical Nursing (PN) and Pharmacy Technician (PT) programs at Sheridan Institute. PT and PN students enrolled in MATH16532 during their first term were surveyed to determine student attitudes and skills gained from participating in an online course. Students were then followed up during their second term studies to determine transferability of skills gained. Initially, students did not exhibit a positive attitude towards the online version of Math16532. Participation in the online version of MATH16532 however allowed students to enhance their written ability and critical appraisal skills, gain time management skills, and become independent learners. PT and PN students preferred an orientation session at the beginning of the course and a well organized, easy-to-navigate course. Even though considered as predominantly digital native students, both student groups remained anxious throughout the course regarding the online delivery and preferred a hybrid mode of delivery. Despite the initial resistance to an online math course, students indicated that they would retake the course again in an online format towards the end of the course and there appeared to be a trend to enrol in another online course. Several recommendations regarding the design and construct of online courses in a 2-year college program are provided to facilitate acceptance of online learning for students enrolled in such programs.     

Comparing the social knowledge construction behavioral patterns of problem-based online asynchronous discussion in e/m-learning environments

In recent years, researchers have conducted various studies on applying wireless networking technology and mobile devices in education settings. However, research on behavioral patterns in learners' online asynchronous discussions with mobile devices is limited. The purposes of this study are to develop a mobile learning system, mobile interactive teaching feedback system (MITFS), linked to both mobile devices and the internet, to support learners with online asynchronous discussion, and combine content analysis and sequential analysis to compare and contrast the social knowledge construction behavioral patterns of problem-based asynchronous discussion in e-learning and m-learning environments. This study investigated four weeks of online discussions in an “Introduction to Computer Science” course involving forty first year university students. The control group (online asynchronous discussion without mobile devices) and the experimental group (online asynchronous discussion with mobile devices) in the group discussions were explored. By using content analysis and sequential analysis for the problem-based online asynchronous discussion of the behavioral patterns and differences between students in control and experimental group, the results showed that using mobile devices in online asynchronous discussion influenced students' learning performance. Some interesting results were found. Firstly, when the students used mobile devices in discussion situations, they could more engage in reflecting thinking, sharing more information, and further facilitating social knowledge construction among group members. Secondly, the experimental group performed better than the control group in terms of participation and diversity in knowledge construction behavioral patterns. Finally, based upon the findings, some implications are proposed for further research.     

Audience,integrity, and the living document: eFolio Minnesota and lifelong and lifewide learning with ePortfolios

Policies and programs focused on using ePortfolios to support lifelong and lifewide learning should be informed by research. This article presents the results from research on eFolio Minnesota, a project that makes ePortfolio software available to all residents of the State of Minnesota in the United States. The most active portfolio authors of all ages are using eFolio for a wide range of interconnected purposes, with educational planning at the center, over time in multiple roles as students, educators, and workers. In the process of composing a portfolio, the authors who say eFolio has had a highly significant impact on their learning move from an experimental stage into a living document stage. In this second stage, authors are likely to have a strong sense of and connection to audience, real and imagined, and to see their portfolios as having integrity, as being faithful representations of their lives across roles and over time. Portfolio projects committed to supporting learning throughout life should enable access, foreground planning, promote findability, cultivate audiences, capture activity, enable layering, foreground the personal, cultivate collaborative contexts, and promote integral introductions.     

Comparing the role of ICT literacy and anxiety in the adoption of mobile learning

This paper explores the impact of ICT anxiety, ICT literacy, perceived ease of use and usefulness on the adoption of mobile learning. A modified version of the Technology Adoption Model was used to measure student and educator intention to adopt mobile learning. The research questions were tested using structural equation modelling. Two questionnaires were developed (one for students and one for educators) and used to measure ICT literacy and attitudes and perceptions towards mobile learning. Differences and similarities were found between students and educators on the relative importance of the influence of these factors on intention to adopt. A basic level of ICT literacy and an advanced level of mobile literacy had an impact on intention to adopt but an advanced level of ICT literacy was not found to have any effect.
