Design and development of a technology enhanced hybrid instruction based on MOLTA model: Its effectiveness in comparison to traditional instruction

Using the model for learning and teaching activities (MOLTA), a new technology enhanced hybrid instruction was designed, developed and implemented. The effectiveness of the hybrid instruction in regard to students’ achievement, knowledge retention, attitudes towards the subject, and course satisfaction was evaluated in comparison to traditional classroom instruction. Experimental study with pre-test, post-test control group design was carried out. The sample of the study consisted of 50 university students enrolled in “Computer Networks and Communication” course. The control and experimental groups composed of 24 and 26 students respectively, and the experiment lasted 14 weeks. The findings of the study indicated no significant difference between the hybrid course and the traditional course in students’ achievement, knowledge retention, satisfaction, and attitude.     

Audio peer feedback to promote deep learning in online education

We investigated the relation between providing and receiving audio peer feedback with a deep approach to learning within online education. Online students were asked to complete peer feedback assignments. Data through a questionnaire with 108 respondents and 14 interviews were used to measure to what extent deep learning was perceived and why. Results support the view that both providing and receiving audio peer feedback indeed promote deep learning. As a consequence of the peer feedback method, the following student mechanisms were triggered: “feeling personally committed,” “probing back and forth,” and “understanding one's own learning process.” Particularly important for both providing and receiving feedback is feeling personally committed. Results also show that mechanisms were a stronger predictor for deep learning when providing than when receiving. Given the context in which instructors face an increasing number of students and a high workload, students may be supported by online audio peer feedback as a method to choose a deep approach to learning.     

Managing programmed instruction and collaborative peer tutoring in the classroom: Applications in teaching Java™

To fulfill part of the course requirements, 34 undergraduate students in two courses completed an online programmed instruction tutor as the first technical training exercise in a Java™ programming course designed for information systems majors. The tutor taught a simple JApplet program to display a text string within a browser window on the Web. Students in the first course next participated in a collaborative peer tutoring session, based on the JApplet program, followed by a lecture on the program and by successfully running the program on the Web. For the second course, the peer tutoring session was scheduled after the lecture and after successfully running the program. Students in both courses completed tests of far transfer (“meaningful learning”) and software self-efficacy before using the tutor and on several subsequent occasions following that initial learning. Students in the second course also completed a 4-item scale to assess the development of classification and functionality knowledge regarding elements of the program. Students in both courses showed progressive improvement in all performance measures across the several assessment occasions. Students’ positive ratings of the effectiveness of both the tutor and the collaborative peer tutoring supported the value of these learning experiences in a technical knowledge domain. The results of this study, based on student performance observed within the context of the classroom, show the importance of providing a range of synergistic learning experiences that culminate in a level of skill and confidence that prepares and motivates all students for advanced instruction in Java. They also show how to manage the instructional techniques in the classroom to accomplish that educational outcome.     

Comparing hybrid learning with traditional approaches on learning the Microsoft Office Power Point 2003 program in tertiary education

The purpose of this study was to determine the effectiveness of a hybrid learning approach to deliver a computer science course concerning the Microsoft office PowerPoint 2003 program in comparison to delivering the same course content in the form of traditional lectures. A hundred and seventy-two first year university students were randomly assigned into two teaching method groups: traditional lecture instruction (TLI) and hybrid lecture instruction (HLI). Each group received six 95-min periods of instruction divided into 4 sections: a) 5-min brief outline of the key learning points, b) 40-min lecture on general knowledge c) 45-min constructivist-inspired learning activities and d) 5-min summary on key learning points. In the beginning and the end of this study students completed a 17-item multiple choice knowledge test. Two-way analysis of variances (ANOVA), with repeated measures on the last factor, were conducted to determine effect of method groups (TLI, HLI) and measures (pre-test, post-test) on knowledge test. The measures main effect was significant, as well as the groups x measures interaction effect. Two independent-samples t test were conducted to follow up the significant interaction. Differences in mean ratings of knowledge performance between the two teaching groups were not significantly different at first measure, while the TLI method group yielded a significantly lower mean rating at second measure. The findings indicated that HLI approach might be a superior option for undergraduate students on learning the Microsoft office PowerPoint 2003 program.     

Optimising assembly learning in older adults through the manipulation of instruction

The present investigation assessed the putative benefits of reducing instructions for older adults' learning of an assembly task. Young and older adults had to build a product by assembling six components. Two groups practiced following instruction methods that differed in the degree of explicit information they conveyed about the correct assembly order. After practice, retention, consolidation of performance (tested immediately after practice and on a separate day, respectively) and stability of performance (tested by introducing a concurrent second task) were assessed. Younger adults showed similar performance levels for both instruction methods. Older adults, however, showed similar retention but clearly weaker consolidation and stability of performance following less encompassing instructions. Contrary to expectations, enhancing the involvement of explicit processes allowed older adults to gain a more permanent and stable performance improvements. The findings are discussed relative to the characteristics of the assembly task.     

Assessing the effects of interactive blogging on student attitudes towards peer interaction,learning motivation,and academic achievements

Blogs have been increasingly used to supplement traditional classroom lectures in higher education. This paper explores the use of blogs, and how student attitudes towards online peer interaction and peer learning, as well as motivation to learn from peers, may differ when using the blog comments feature, and when students are encouraged to read and comment on each other's work. We contrast two ways blogs affect learning engagement: (1) solitary blogs as personal digital portfolios for writers; or (2) blogs used interactively to facilitate peer interaction by exposing blogging content and comments to peers. A quasi‐experiment was conducted across two semesters, involving 154 graduate and undergraduate students. The result suggests that interactive blogs, compared with isolated blogs, are associated with positive attitudes towards academic achievement in course subjects and in online peer interaction. Students showed positive motivation to learn from peer work, regardless of whether blogs were interactive or solitary.     

Developing a reciprocal teaching/learning system for college remedial reading instruction

In face-to-face instruction of Reciprocal Teaching (RT), students’ reading processes and dialogues with their peers are hardly observed. As a result, the teacher has few clues to identify students’ learning difficulties and provide further scaffoldings. To record students’ reading processes and enhance their comprehension, this study reports on the design of an online reciprocal teaching and learning system to support teachers and students in college remedial reading instruction. A sample of 129 under-prepared college students voluntarily signed up to participate in a remedial reading program. They were encouraged to use multiple strategies such as predicting, clarifying, questioning, and summarizing, which were supported by the functionalities of dialogue box, chat room, discussion forum, and annotation tool in the system. In this study, it was observed that students employed the multiple strategies to enhance their reading comprehension, as revealed by the students’ reading processes recorded in the system. When encountering difficulties in using these multiple strategies, students expressed that they observed and learned from the teacher’s or their peers’ externalization of strategy usage. Students’ reading progress in the remedial instruction incorporating the RT system was also identified by the pre- and post-tests. This study suggests that there may be benefits for teachers in encouraging students to interact with others in order to clarify and discuss comprehension questions and constantly monitor and regulate their own reading.     

A gamified peer assessment model for on-line learning environments in a competitive context

Peer Assessment (PA) offers a powerful solution that helps teachers in online learning environments to correct essays by distributing the workload among students. Nevertheless, the quality of the results in PA depends on good evaluations of reviewers. Thus, the main drawback for scaling up the use of PA is the presence of inadequate behaviours, such as being too harsh or too soft in the assessment, or even not offering a helpful feedback. This usually occurs due to the lack of motivation and engagement of students in the PA process. To deal with this problem, this paper proposes a gamified peer assessment model, where gamification elements are used to engage students in PA activities. Two experiments using the proposed model within an intelligent tutoring system called MeuTutor shows satisfactory outcomes. We verified that the average grade given by students to an essay are equivalent to those given by experts, but the time and costs to complete the assessments were largely reduced. Furthermore, the use of gamification helped to increase the amount of students' access to the system in 64.28%; increase in 10.53% the number of essays written and submitted; and improve the quantity and quality of assessments for each essay.     

Behaviour modelling,instruction and exploration training approaches in group and individual contexts

Behaviour modelling has been associated with higher learning outcomes compared to other training approaches. These cumulative research findings create imperative to examine underlying causal mechanisms or contingency factors that may promote behaviour modelling's advantages even further. We propose group-based learning as one contingency factor because there exists greater opportunity for observation, imitation and feedback. We use a two-by-three experimental laboratory design involving 84 subjects to test for an interaction effect between training context (group-based, individual-based) and training approach (behaviour modelling, exploration, instruction) on several learning outcomes. We use hierarchical regression to show that, while the interaction effect was not significant, the training approach main effect was significant. Consistent with expectations, behaviour modelling outperformed exploration on task performance. There were no significant differences between behaviour modelling and instruction. We conclude that behaviour modelling is associated with higher task performance levels on a complex word-processing task when compared to exploration.     

Analysis of studies of the effects of computer-assisted instruction on the mathematics performance of students with learning disabilities

The purpose of this study was to conduct a meta-study of computer-assisted instruction (CAI) studies in mathematics for students with learning disabilities (LD) focusing on examining the effects of CAI on the mathematics performance of students with LD. This study examined a total of 11 mathematics CAI studies, which met the study selection criterion, for students with LD at the elementary and secondary levels and analyzed them in terms of their comparability and effect sizes. Overall, this study found that those CAI studies did not show conclusive effectiveness with relatively large effect sizes. The methodological problems in the CAI studies limit an accurate validation of the CAI’s effectiveness. Implications for future mathematics CAI studies were discussed.     

Learning style as an influence on the effectiveness of self-paced computer-assisted instruction: Preliminary results

Many have studied the relative effectiveness of self-paced, computer-assisted instruction. An experiment was conducted to investigate whether people of certain who exhibit certain learning styles are more successful using a self-paced instructional package. The preliminary results reported here indicate that differences in learning performance can be identified for different learning style categories (as measured by the Myers Briggs Type Indicator (MBTI).     

Acceptance of competency-based workplace e-learning systems: Effects of individual and peer learning support

Current endeavors to integrate competency-based learning approaches with e-learning systems designed for delivery of training to adult learners in the workplace are growing. However, academic efforts in examining learners’ perceptions of, and reactions toward, this technology-delivered pedagogical innovation are limited. Drawing together perspectives from the literature on training and instructional design and technology acceptance, this research proposed a conceptual model to examine the influences of perceived individual and social learning support on employees’ acceptance of competency-based e-learning systems. Structural equation modeling and multi-group structural equation modeling techniques were applied to sample data collected from work settings in Mainland China. The results show the positive effects of perceived individual learning support and perceived support for promoting a norm of cooperation on employees’ intention to use the competency-based e-learning system. It was also found that perceived support for enhancing social ties had a negative effect on employees’ behavioral intention. The gender, age, prior experience, and work experience differences in the main effects were also investigated. Besides, qualitative data collected via semi-structured in-depth interview provide complementary evidence to the findings.

Learning with new information technologies in schools: perspectives from the psychology of learning and instruction

Abstract  The starting point of the present paper is that the New Information Technologies can only contribute substantially to the improvement of schooling, if they are appropriately embedded in powerful learning environments. The realization of this embedding requires that inquiry and development relating to educational computing are more explicitly based on recent research on learning and instruction, because this domain of investigation has produced an empirically underpinned knowledge base that can guide and orient the design of rich and powerful computer-supported learning environments. In that perspective a series of important and relevant findings of research on learning and instruction are reviewed; they relate to the three major components of a theory of learning from instruction, namely a theory of expertise describing skilled performance in a domain, a theory of the acquisition processes required to achieve competence, and a theory of intervention strategies that are appropriate for eliciting those acquisition processes.     

Using a wiki to evaluate individual contribution to a collaborative learning project

Abstract   One critical issue arising in the educational use of collaborative learning concerns the teacher's difficulty in evaluating the contribution and participation of each student in group-work. This article aims to illustrate and discuss a methodology that enables evaluation of the collaborative learning process based on co-writing in a wiki environment. After considering the effectiveness of co-writing as a strategy of collaborative learning, the article will highlight issues regarding methods for evaluating each student's contribution to the collaborative process and to the group's overall action. A solution will be proposed to address the problem. It is based upon the elaboration of information traced automatically by wiki, employing survey grids and formulae developed ad hoc to calculate participation and contribution indexes. These tools will be illustrated together with their application in two university courses. Results demonstrate the added value given by the proposed approach to the evaluation process of co-writing. However, these findings also highlight critical issues and some possible remedies for the lack of specific wiki functions to automatically extract information required for quantitative analysis of the actions taken by members of the learning group.     

The effects of social messaging on students' learning and intrinsic motivation in peer assessment

This study aims to gain a better understanding of how the newly arisen social messaging may impact the practice of peer assessment. Seventy-nine ESL (English as second language) students reviewed each other's English essays in three peer assessment groups: a three-member group using wiki (wiki group), a three-member group using social messaging (small messaging group), and a six-member group using social messaging (big messaging group). Data analysis suggested that peer assessment facilitated by social messaging can be at least of the same effectiveness as wiki-facilitated peer assessment on ESL students' writing skills and intrinsic motivation. In addition, the findings indicated that students in the small messaging group outperformed students in the big messaging group on essay writing and reported a significantly higher rating on perceived competence, a positive indicator of the behavioural measures of intrinsic motivation, than students in the big messaging group.

From integrative to game‐based integrative peer response: high ability versus low ability

Peer response is useful to improve student writing. However, traditional peer response takes a single mode, which has some problems, such as effort for preparation of documents or ambiguous feedback. To address these problems, this study presents two peer response approaches, that is, an integrative approach and a game‐based integrative approach. Additionally, whether students with these two peer response approaches and those with a non‐peer response approach performed differently is examined in this study, where students' ability levels were also considered. The findings suggest that students with the peer response generally demonstrated better writing performance than those without the peer response. Furthermore, students with the game‐based integrative approach showed better writing quality than those with the integrative approach. Moreover, the former was more helpful in giving direct feedback on surface features and criticism than the latter. However, the usefulness of peer response approaches was associated with ability levels. More specifically, the integrative approach was beneficial for the high‐ability students to improve on their written expression in the aspect of length of composition, while the game‐based integrative approach was advantageous to enhance the low‐ability students' writing quality in the aspect of clear paragraph.     

Web-based programmed instruction: evidence of rule-governed learning

Seventeen graduate students in two classes worked on a web-based programmed instruction tutoring system as the first technical exercise in a Java^TM programming course. The system taught a simple Java applet to display a text string in a browser window on the world wide web. Students completed tests of near transfer and far transfer before and after using the tutor and again after a lecture on the material. The results showed that performance improved over pre-tutor baseline on all assessments, to include the far transfer test, which required integrating information in the tutor into a rule to apply to solve a novel programming problem not explicitly taught in the tutor. Software self-efficacy also increased across four assessment occasions. These data show that programmed instruction can produce problem solving skills and can foster student confidence, based upon the documented mastery of fundamental material in a technical domain. An investigative approach that follows systematic replication, rather than null hypothesis refutation, may be best suited to assess the impact and dependability of competency-based instructional systems.     

Structuring the peer assessment process: a multilevel approach for the impact on product improvement and peer feedback quality

In order to optimize students' peer feedback processes, this study investigates how an instructional intervention in the peer assessment process can have a beneficial effect on students' performance in a wiki environment in first‐year higher education. The main aim was to study the effect of integrating a peer feedback template with a varying structuring degree. The present study involved three conditions: a no structure, a basic structure and an elaborate structure condition. Due to a clear hierarchical structure, in which over time (level 1), 168 students (level 2) are nested within 37 groups (level 3), multilevel analysis was performed to examine the effect of time, student and group level influences on students' peer feedback quality and product scores. The results revealed that both peer feedback quality and product scores increase significantly for all conditions over time, after multiple practice occasions. In addition, after several practice occasions, significant differences were found between the conditions in both peer feedback (elaborate higher than no structure) and product scores (elaborate and basic higher than no structure). Building on this, limitations, directions for future research and practical implications are presented.
