A review of: Zhang, Li, Watson, Erin M. and Banfield, Laura. "The Efficacy of Computer-Assisted Instruction Versus Face-to-Face Instruction in Academic Libraries: A Systematic Review." The Journal of Academic Librarianship 33.4 (July 2007): 478-484. Objective – To conduct a systematic review of several studies comparing the efficacy of face-to-face versus computer-assisted instruction (CAI) for teaching basic library skills to patrons of academic libraries. Design – Systematic review of existing studies (randomised controlled trials and controlled trials). Setting - College and university libraries Subjects – The subjects studied were patrons of any type of academic library, whether university, college, or other post-secondary institution, receiving instruction in basic library skills. Ten studies were included in the review, of which seven were done in the United States, two in Australia, and one in Canada. The total number of subjects in all of the studies under review was 1283. Nine of the studies focused on undergraduates enrolled in specific courses (undergraduate courses ranging widely in subject area, or in one case a first year experience program); the other study focused on library instruction methods taught to students in a graduate research methods course, yet the study was still intended to measure the efficacy of library instruction methods, yet the study was still intended to measure the efficacy of library instruction methods. Methods – One included study was a randomised controlled trial; the other nine were controlled trials. The date range under consideration was for studies done between 1990 and 2005. All original studies were required to compare the efficacy of face-to-face versus CAI instruction. Both information skills and students’ reactions to receiving the instruction were considered. To identify appropriate studies, searches were done across the following library and education-related databases: LISA, ERIC, and Library Literature. The authors screened the 728 unique studies’ bibliographic information for relevance against four criteria: studies had to be of a particular type of design (randomised controlled trials, controlled trials, cohort studies, and case studies), with a sample size greater than one and with pre- and post-test measurements; study participants had to be academic library patrons; the study needed to compare CAI and face-to-face instruction; and both the students’ information skills and reactions to the instruction had to be measured. This left 40 unique studies, which were then retrieved in full text. Next, studies were selected to meet the inclusion criteria further using the QUOROM format, a reporting structure used for improving the quality of reports of meta-analyses of randomised trials (Moher, David et al 1896 - 1900). Evaluation of methodological quality was then done using a dual method: authors Watson and Zhang assessed the studies independently, each using the “Checklist for Study Quality” developed by Downs and Black (Downs, Sara H. and Black, Nick 377-384), adapted slightly to remove non-relevant questions. After analysis, when additional information was needed, original study authors were contacted. Finally, ten studies were included in the analysis. The instruction sessions covered many topics, such as catalog use, reading citations, awareness of library services and collections, basic searching of bibliographic databases, and more. But all could qualify as basic, rather than advanced, library instruction. All studies did pre- and post-tests of students’ skills – some immediately after instruction, and others with a time lapse of up to six weeks. Most authors created their own tests, though one adapted an existing scale. Individual performance improvement was not studied in many cases due to privacy concerns. Main Results - Nine of the ten studies found CAI and face-to-face instruction equally effective; the tenth study found face-to-face instruction more effective. The students’ reaction to instruction methods varied – some students felt more satisfied with face-to-face instruction and felt that they learned better, while other studies found that students receiving CAI felt more confident. Some found no difference in confidence. It was impossible to carry out a meta-analysis of the studies, as the skills taught, methods used, and evaluation tools in each case varied widely, and the data provided by the ten studies lacked sufficient detail to allow meta-analysis. As well, there were major methodological differences in the studies – some studies allowed participants the opportunities for hands-on practice; others did not. The CAI tutorials also varied – some were clearly interactive, and in other studies, it was not certain that the tutorial allowed for interactivity. The authors of the systematic review identified possible problems with the selected studies as well. All studies were evaluated according to four criteria on the modified Downs-Black scale: reporting, external validity, and two measures of internal validity (possible bias and possible confounding). A perfect score would have been 25; the mean score was 17.3. Areas where authors lost points included areas such as failure to estimate data variability, failure to report participants lost to follow-up, failure to have blind marking of pre- and post-tests, failure to allocate participants randomly, and a variety of other areas. As well, few studies examined participants’ confidence level with computers before they participated in instruction. Conclusion – Based on this systematic review, CAI and face-to-face instruction appear to be equally effective in teaching students basic library skills. The authors of the study are reluctant to state this categorically, and issue several caveats: a) only one trial was randomised; b) seven of the studies were conducted in the USA, with the others being from Canada and Australia, and learning and teaching styles could be very different in other countries; c) the students were largely undergraduates, and the authors are curious as to whether results would be similar with faculty, staff, or older groups (though of course, not all undergraduates are traditional undergraduates); d) the tests ranged widely in design, and were largely developed individually, and the authors recommend developing a validated test; and e) if the pre- and post-tests are identical and given in rapid succession, this could skew results.

The purpose of this study was to investigate the evidence base for using computer-assisted instruction (CAI) to improve the reading comprehension of students with learning disabilities (LD). Twelve peer-reviewed studies (seven comparison group studies, five single-case studies) met selection criteria and were evaluated according to the relevant What Works Clearinghouse (WWC) procedures and standards. Results showed that seven studies (five comparison group and two single-case studies) met WWC standards with or without reservations. Key instructional features employed in CAI studies meeting the WWC standards without reservations included practice opportunities, self-correction and immediate corrective feedback, teacher-directed instruction, and contingencies for enhancing student motivation and engagement. Implications for future research and suggestions for using quality indicators to improve the rigor of future CAI investigations are discussed.

Research in computer-assisted language learning (CALL) has neither traditionally nor recently had a language or setting-specific emphasis, one that would have established a distinction between second language learning (SLL) as opposed to foreign language learning (FLL) applications in its attempts to answer principled CALL questions. For example the two anthologies of essays, studies, and reports on CALL theory and practice by Smith (1987; 1989), the papers on CALL research compiled by Dunkel (1991b), and the collection of international perspectives edited by Pennington and Stevens (1992) summarize work done in the 1980s and provide directions and guidelines for work to be done in the 1990s with implications for both SLL and FLL. As this continues to be the case in recent CALL research, an FLL emphasis in the chapter of non-English L2 instructional context has been maintained exclusively for the discussion of software; whenever the rationale for the design and implementation of FLL software was based on second language acquisition theory or findings from empirical ESL-oriented CALL investigations, the respective research source was examined and cited.

The adoption of methods and strategies validated through rigorous, experimentally oriented research is a core professional value of special education. We conducted a systematic review and meta-analysis examining the experimental literature on Technology-Aided Instruction and Intervention (TAII) using research identified as part of the National Autism Professional Development Project. We applied novel between-case effect size methods to the TAII single-case research base. In addition, we used meta-analytic methodologies to examine the methodological quality of the research, calculate average effect sizes to quantify the level of evidence for TAII, and compare effect sizes across single-case and group-based experimental research. Results identified one category of TAII—computer-assisted instruction—as an evidence-based practice across both single-case and group studies. The remaining two categories of TAII—augmentative and alternative communication and virtual reality—were not identified as evidence-based using What Works Clearinghouse summary ratings.

This article presents a discussion and analysis on the implementation of social networks to support the learning of a second language (L2) in the field of Computer Assisted Language Learning (CALL); an area that has regained especial significance in the post pandemic era. Through a cumulative case study report that compares and contrasts several research studies carried out at different times, this article first brings to discussion the strengths that social networks offer for their implementation in L2 instruction. To continue the discussion, the issues of teachers’ CALL training and access are presented as weaknesses for a successful implementation of social networks in the L2 instruction. It is argued that social networks cannot work as effective tools for this purpose without the guidance of a properly trained instructor. Nevertheless, attaining such an ideal condition is challenging considering the problems that might emerge during its implementation. Although it is common that language teachers to some extent include this resource for their L2 classes, more research needs to be done to produce literature that sheds light on the aspects that need to be worked on to take real advantage of this type of technology.

Before arriving in a host country, international students may be motivated to complete some institutional requirements online. Many studies address computer-assisted instruction for second-language students, but few focus on fully online English for Academic Purposes (EAP) writing courses. This comparative case study, grounded in action research, examined the extent to which a fully online version of a graduate-level EAP course offered to international students at a North American university achieved comparable outcomes to a face-to-face version. A quantitative and qualitative analysis of study participants’ performance and course evaluations indicated that the outcomes and student satisfaction of both cohorts were comparable. However, an examination of the participants’ final research papers and online interactions revealed differences and challenges. Based on these findings, it is recommended that future online courses provide more instruction on source integration, library research, and building an interactive learning community. Overall, the findings suggest that when carefully designed, assessed, and refined, fully online courses hold strong promise in EAP academic writing contexts. Les étudiantes et étudiants internationaux tiennent parfois à remplir certaines exigences institutionnelles en ligne avant de se rendre dans leur pays d’accueil. L’enseignement assisté par ordinateur pour les apprenantes et apprenants d’anglais langue seconde fait l’objet de nombreuses études, mais peu d’entre elles portent sur des cours d’écriture d’anglais académique (EAP) complètement dispensés en ligne. Entièrement basée sur la recherche-action, la présente étude de cas comparative fait état du degré de comparabilité des résultats d’un cours d’anglais académique de deuxième cycle complètement présenté en ligne à des étudiantes et étudiants internationaux inscrits à une université nord-américaine et des résultats obtenus lorsque le même cours était dispensé en personne. Une analyse quantitative et qualitative des rendements des participantes et participants et du cours lui-même a indiqué que les résultats et le degré de satisfaction des étudiantes et étudiants des deux cohortes se valaient. L’examen des rapports de recherche finaux des participantes et participants et celui des interactions en ligne ont toutefois révélé des écarts et des défis. Sur la base de ces constatations, il est recommandé que les futurs cours en ligne fournissent davantage d’instructions sur l’intégration des sources, sur les recherches en bibliothèque et sur la construction d’une communauté d’apprentissage interactif. Dans l’ensemble, les constatations de l’étude suggèrent que, s’ils sont soigneusement conçus, évalués et peaufinés, les cours complètement dispensés en ligne sont très prometteurs dans des contextes d’écriture en anglais académique.

The introduction of basic computer media for early childhood is very important because it is one of the skills that children need in this century. Need to support parents and teachers in developing the implementation of the use of computer technology at home or at school. This study aims to determine and understand the state of learning conducted based on technology. This research uses a qualitative approach with a case study model. This study involved 15 children and 5 parents. Data obtained through interviews (children and parents) and questionnaires for parents. The results showed that children who were introduced to and taught basic computers earlier became more skilled in learning activities. Suggestions for further research to be more in-depth both qualitatively and quantitatively explore the use of the latest technology to prepare future generations who have 21st century skills.

During reading, readers never fixate on all words in the text; shorter words sometimes gain zero fixation and skipped by the reader. Relying on E-Z Reader Model, this research hypothesized that a similar skipping effect also exists for a second language. The current study examined word skipping rates in EFL (English as a Foreign Language) with 75 EFL learners by using eye tracking methodology. The results showed that word skipping was affected by EFL reading proficiency significantly and articles (a, an, the) were skipped more than content words. Furthermore, more skilled learners were observed to have less fixation count and skipped more words during reading while less skilled learners employed more fixations and skipped less words. Eye tracking as a novel method to observe learner development and progress in EFL reading was also discussed. References Altarriba, J., Kroll, J. F., Sholl, A.. & Rayner, K. (1996).

Although much has been written about learning in online discussion, the research literature reveals the need for further empirical research to be carried out.  For example, the use of online discussion is often seen as a means by which students can engage in a socially constructivist approach to learning, (Pena-Shaff et al., 2005; Hudson et al., 2006; Schrire, 2006) whilst others raise questions about the depth of engagement and the preparedness to learn in this socially constructivist context (Hawkey, 2003; Roberts and Lund, 2007).  The need to gain further understanding of learning through discussion is raised by Ravenscroft (2005); McConnell (2006); Goodyear and Ellis (2008).  This study adds to empirical research by exploring students’ engagement with online discussion at an individual and course level. Two key research questions are: What are the different approaches taken by students when responding to learning activities which ask them to engage in online discussion?  What are students’ perceptions of how their engagement in online discussion impacts on their learning and the learning of others?  The study is qualitative, phenomenographic in nature drawing on six case studies of Higher Education students’ engagement with online discussion.  A rich set of empirical data is gathered within the case studies.  A grounded approach to data collection and analysis is used, including the analysis of interview data in order to hear the students’ voices about their experiences.  The findings from the analysis of the case studies reveal different strategies that students use when engaging in online discussion, and diverse students’ views of learning through online discussion, even from within the same course context.  A framework for learning through online discussion emerges from the discussion.

The last 10 years have seen an explosion in the number of microcomputers available for use in the educational system. However, teachers have little experience in using microcomputers in the classroom and teachers' perceptions of this innovation have seldom been taken into account when implementing computers into the classroom. This case study was undertaken to delineate teachers' perceptions of computers during the implementation of a 14 computer English/Social Studies computer lab being installed as a teaching tool. Twelve teachers were interviewed during June 1985, just before the implementation of the lab, and again in June 1986, one year after the lab's implementation. The interviews were analysed to determine whether past experience influenced teachers' present perceptions of the usefulness of the new computer lab. The study found that Naive Users, or teachers with little or no experience with computers made more use of the computer lab as an aid in teaching the writing process than did Experienced Users who confined themselves to having students use the computer as an electronic typewriter. The study also found that the presence of an Aide to help students with the technical aspects of word processing freed the teachers to use the lab as writing tool without necessarily becoming technically proficient with the computer themselves. As computers become more common in the school system, it becomes important that teachers recognize and understand that these new tools are useful in helping to teach students to write. Otherwise computers may largely become a subject of study rather than a tool suitable for student use in many curricular areas.

This thesis presents a case study of one tutor in two tutoring sessions using electronic drafts in the Ball State Writing Center, focusing on the sessions' power dynamics. Writing centers have developed nondirective tutoring pedagogies in order to help tutors navigate the power dynamics of sessions with paper drafts. While these pedagogies have recently been adapted for tutoring online, attention has not yet been focused on face-to-face sessions using a computer. Using conversational, textual, and user interface analysis, this study provides thick descriptions of the power dynamics of each tutoring session, analyzing the interactions between tutor, student and computer. The descriptions of both sessions show them to be vastly unique and complex, undermining strict dichotomies between directive and nondirective tutoring. The use of the computer reflects the overall dynamics of each tutorial and raises questions about the ways in which tutors and students prefer to use computers in tutoring sessions.
