The educational impact of metacognitive group coordination in computer-supported collaborative learning

Group coordination is a crucial component for successful collaborative learning, but is hard to achieve in an online learning environment. A web-based group coordination tool was developed based on metacognitive scaffolding principles for the study. The tool was implemented in an online course for a group project and its effects were investigated. A total of 59 students formed into 20 groups participated in and completed a project while being guided with the tool. Based on response rate to metacognitive prompts of the tool, groups were categorized as Active Metacognitive Team (AMT, n = 30) or Passive Metacognitive Team (PMT, n = 29). AMT showed higher positive interdependence than PMT at the end of the project. AMT perceived reciprocal help among group members while PMT did not. AMT also evaluated its group process higher than PMT did. These results show that groups who more actively used the coordination support tool established positive interdependence, engaged in positive interactions, and had enhanced group productivity.     

The effects of trust and constructive controversy on student achievement and attitude in online cooperative learning environments

This study investigated the effects of trust and constructive controversy on student achievement and attitude in online cooperative learning environments. Students in one university course were randomly assigned to one of the two treatment groups after they took part in a common initial workshop on general cooperative learning skills. The “trust” and the “constructive controversy” groups received subsequent associated skills training. The overall results indicated that after each group received the treatment during online cooperative group activities, the “trust” groups had significantly higher achievement than the “constructive controversy” groups. In addition, the “trust” groups had significantly more positive attitudes toward online cooperative learning than the “constructive controversy” groups. Specifically, using “trust” building strategies was significantly more effective than using “constructive controversy” strategies for improving the ‘openness and sharing’ and ‘acceptance and support’ components of student attitudes in online cooperative learning environments.     

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.     

Hypermedia annotation presentation: The effect of location and type on the EFL learners’ achievement in reading comprehension and vocabulary acquisition

This study investigated the effect of gloss presentation in different text locations whilst participants read EFL texts in a hypermedia environment. Seventy-eight undergraduate EFL learners read and summarized seven texts and completed a vocabulary assessment. The number of propositions recalled in each summary was recorded. The data suggest that reading passages with hypermedia annotations significantly benefits passage comprehension and vocabulary (compared to reading passages with no annotations). The best performance was observed in the condition where glosses were placed after the glossed word. The study also reported large observed score mean differences for the definition gloss type of 3–5-words.     

The goal specificity effect on strategy use and instructional efficiency during computer-based scientific discovery learning

Using a computer-based scientific discovery learning environment on buoyancy in fluids we investigated the effects of goal specificity (nonspecific goals vs. specific goals) for two goal types (problem solving goals vs. learning goals) on strategy use and instructional efficiency. Our empirical findings close an important research gap, because in earlier studies the goal specificity effect either was restricted to one goal type or goal type was confounded with goal specificity. In addition, there is hardly a study with empirical evidence for the goal specificity effect on strategy use, which counts even more for a cognitive cost-benefit ratio as a dependent variable. Instead, in earlier studies the goal specificity effect has been attributed to differences in strategy use and cognitive cost-benefit ratio in a rather theoretical way. In the present study for strategy use an interaction was found between goal specificity and goal type, indicating that the goal specificity effect occurs only in case of problem solving goals, but not in case of learning goals. Compared to students provided with specific problem solving goals, students who worked on nonspecific problem solving goals, used a control of variables-strategy more frequently. Additionally, we found a main effect of goal specificity on instructional efficiency for both of the goal types, pointing at a more favorable relationship between performance gain and cognitive load caused by nonspecific goals.     

The effect of reflective learning e-journals on reading comprehension and communication in language learning

This study focused on the use of reflective learning e-journals in a university web-based English as a foreign language (EFL) course. In the study, a multimedia-based English programme comprising fifteen different units was delivered online as a one-semester instructional course. Ninety-eight undergraduate students participated, and they were divided into two groups: the treatment group used reflective learning e-journals, while the control group completed content-related exercises. The study investigated the effects of reflective learning e-journals and how students used them to aid learning. Results show that when learning from web-based instruction, students who used reflective learning e-journals outperformed students who did not do so in terms of reading comprehension. Using reflective e-journals improved the academic performance of learners in the online course. In addition, journal writing students claimed that they also improved their organisational skills and writing abilities through their reflective learning e-journal writing and found the journal writing to be a very helpful tool in reviewing the course and preparing for the exam.     

The impact of goal specificity and goal type on learning outcome and cognitive load

Two hundred and thirty three 15-year old students conducted experiments within a computer-based learning environment. They were provided with different goals according to an experimental 2 × 2 design with goal specificity (nonspecific goals versus specific goals) and goal type (problem solving goals versus learning goals) as factors. We replicated the findings of other researchers that nonspecific problem solving goals lead to lower cognitive load and better learning than specific problem solving goals. For learning goals, however, we observed this goal specificity effect only on cognitive load but not on learning outcome. Results indicate that the goal specificity affects the element interactivity of a task and cognitive load with both, problem solving goals or learning goals. But differences in overall cognitive load are not sufficient for explaining differences in learning outcome. Additionally, differences in strategy use come into play. Specific problem solving goals seem to restrict students to use a problem solving strategy whereas nonspecific problem solving goals or learning goals allow students to use a learning strategy. We conclude that in order to foster learning, students must be provided with goals that allow them to use a learning strategy. Additionally, providing them with nonspecific goals decreases cognitive load and, thus, enables students to learn with less effort.     

The effects of group size and task complexity on deadline reactivity

In contemporary organizations, people are often required to work and learn under increasing time pressures as organizations set deadlines in order to respond to stiffer competition. Human behavioral patterns in the presence of deadlines have been studied quantitatively to show that relatively little time is devoted to tasks early on and that most work is performed in close time proximity to a deadline. This phenomenon, called deadline rush, can be explained by a hyperbolic behavioral model. By employing a decision-making task based on an Anti-Air Warfare Coordinator (AAWC) simulator, the experiment had two group size levels (individuals and teams) and two task complexity levels (low and high). The experimental results showed that deadline reactivity is greater for individuals than teams on low-complexity tasks and task complexity is negatively related to deadline reactivity. The results of this study suggest that different group sizes and task types have a significant impact on production performance and that the setting of deadlines, to the degree possible, may be a relevant means towards managing or improving system performance.     

The identification,implementation, and evaluation of critical user interface design features of computer-assisted instruction programs in mathematics for students with learning disabilities

Critical user interface design features of computer-assisted instruction programs in mathematics for students with learning disabilities and corresponding implementation guidelines were identified in this study. Based on the identified features and guidelines, a multimedia computer-assisted instruction program, ‘Math Explorer’, which delivers addition and subtraction word problem-solving instruction for students with learning disabilities at the early elementary level, was designed and developed. Lastly, usability testing was conducted to assess whether Math Explorer was well-designed in terms of the interface for students with learning disabilities. Given the results of the usability testing, this study corroborated the fact that the critical user interface design features and guidelines in mathematics computer-assisted instruction programs would be essential for facilitating the mathematical learning of students with learning disabilities. Implications for practice and future research were discussed.     

Computer-assisted learning in young poor readers: The effect of grapho-syllabic training on the development of word reading and reading comprehension

Two experiments examine the effects of two computer-based interventions, one with grapho-syllabic training (GST) and another with grapho-phonemic training (GPT) on the development of word recognition and reading comprehension in French children during Grade 1 and Grade 2. In Exp 1, poor readers (N = 27) in second grade were selected and divided into three equal groups, one GST group, one GPT group and a control group. After the session training (10 h), the children from the grapho-syllabic training group outperformed their counterparts in word reading. In Exp 2, poor readers in first grade (N = 18) were divided in two groups, a GST group and a GPT group. Six sessions were conducted in order to examine the possible long-term effect of training (10 h) during 16 months. The results revealed an effect of grapho-syllabic training on silent word recognition, word reading aloud and reading comprehension. A computer-assisted learning (CAL) system based on the syllable, which is considered to be the phonological and orthographic unit that is used by French young readers, could be a promising tool to help poor readers decode words and consequently boost their word recognition and reading comprehension capabilities.     

The impact of goal focus, task type and group size on synchronous net-based collaborative learning discourses

Net-based collaborative learning discourses often suffer from deficiencies such as lack of coherence and coordination. It is suggested that the provision of two functionalities, referencing and typing, which learners may optionally use to ground their contributions during a chat-based discourse, can improve collaborative learning. In particular, we examined if goal focus, type of task and group size affect learning outcomes and the use of these functionalities. A chat-based system, called a learning protocol, implements these functionalities and serves as a net-based collaborative learning environment. Results suggest that a learning protocol is more beneficial for knowledge-acquisition tasks than for problem-solving tasks, and that the use of supporting functionalities increases when goal focus is on the group rather than on the individual. Also, there is a tendency that learning outcomes improve as group size increases. We propose that learning protocols provide potentially valuable design features that can promote net-based collaborative learning.     

The effect of computer-assisted teaching on remedying misconceptions: The case of the subject “probability”

The aim of this study is to determine the effects of computer-assisted teaching (CAT) on remedying misconceptions students often have regarding some probability concepts in mathematics. Toward this aim, computer-assisted teaching materials were developed and used in the process of teaching. Within the true-experimental research method, a pre- and post-test control group study was carried out with 37 seventh-grade students-18 in the experimental group (CAT) and 19 in the control group (traditional teaching). A 12-item instrument, made up of 4 items related to each of the concepts “Probability Comparisons (PC),” “Equiprobability (E),” and “Representativeness (R),” was developed and implemented with the participants. After the teaching intervention, the same instrument was again administered to both groups as a post-test. In light of the findings, it can be concluded that computer-assisted teaching was significantly more effective than traditional methods in terms of remedying students’ misconceptions.     

The impact of computer‐based instruction on the development of EFL learners' writing skills

The current study investigated the application and effectiveness of computer assisted language learning (CALL) in teaching academic writing to Iranian EFL (English as a Foreign Language) learners by means of Microsoft Word Office. To this end, 44 sophomore intermediate university students majoring in English Language and Literature at an Iranian university who had enrolled in a course called Advanced Writing were randomly divided into two groups. As a pre‐test, a pen‐and‐paper writing task was given to both groups at the beginning of the semester. The control group including 24 male and female students was taught based on traditional approach while the experimental group including 20 male and female students was taught based on CALL. At the end of one semester, a pen‐and‐paper writing task was given to both groups. The results of the post‐test revealed that the students who were exposed to computer‐based instruction outperformed their counterparts in terms of using appropriate articles, tense, plural forms and spelling. Moreover, the students in the experimental group produced paragraphs of higher quality. The findings of this study confirmed the efficacy of computer‐based instruction in the development of EFL learners' writing skills.     

Social skills as predictors of communication,performance and quality of collaboration in project‐based learning

The assumption that social skills are necessary ingredients of collaborative learning is well established but rarely empirically tested. In addition, most theories on collaborative learning focus on social skills only at the personal level, while the social skill configurations within a learning group might be of equal importance. Using the integrative framework, this study investigates which social skills at the personal level and at the group level are predictive of task‐related e‐mail communication, satisfaction with performance and perceived quality of collaboration. Data collection took place in a technology‐enhanced long‐term project‐based learning setting for pre‐service teachers. For data collection, two questionnaires were used, one at the beginning and one at the end of the learning cycle which lasted 3 months. During the project phase, the e‐mail communication between group members was captured as well. The investigation of 60 project groups (N = 155 for the questionnaires; group size: two or three students) and 33 groups for the e‐mail communication (N = 83) revealed that personal social skills played only a minor role compared to group level configurations of social skills in predicting satisfaction with performance, perceived quality of collaboration and communication behaviour. Members from groups that showed a high and/or homogeneous configuration of specific social skills (e.g., cooperation/compromising, leadership) usually were more satisfied and saw their group as more efficient than members from groups with a low and/or heterogeneous configuration of skills.     

The effects of computer games on primary school students’ achievement and motivation in geography learning

The implementation of a computer game for learning about geography by primary school students is the focus of this article. Researchers designed and developed a three-dimensional educational computer game. Twenty four students in fourth and fifth grades in a private school in Ankara, Turkey learnt about world continents and countries through this game for three weeks. The effects of the game environment on students’ achievement and motivation and related implementation issues were examined through both quantitative and qualitative methods. An analysis of pre and post achievement tests showed that students made significant learning gains by participating in the game-based learning environment. When comparing their motivations while learning in the game-based learning environment and in their traditional school environment, it was found that students demonstrated statistically significant higher intrinsic motivations and statistically significant lower extrinsic motivations learning in the game-based environment. In addition, they had decreased focus on getting grades and they were more independent while participating in the game-based activities. These positive effects on learning and motivation, and the positive attitudes of students and teachers suggest that computer games can be used as an ICT tool in formal learning environments to support students in effective geography learning.     

The effects of problem-based learning on the classroom community perceptions and achievement of web-based education students

Web-based education as an alternative to face-to-face teaching is now being extended as an application to higher education. Much effort is undertaken to provide multimedia rich, attractive content to learners. While the use of multimedia technologies has a noticeable effect on students’ learning, so does the selected teaching methodology. Underpinned by the Constructivist approach, problem-based learning is one of the methods that could be applied in web-based learning environments. The current study investigates the effects of problem-based learning on students’ classroom community perceptions and their achievement. It focuses on the tertiary level course “Introduction to Computers” offered by the Department of Business Administration of the Distance Education Program at a higher education institution in Turkey. The results indicated that students who worked on problem-based projects felt much more ‘connected’ to other class members when compared to the control group. They achieved higher scores in the post-tests although their online midterm and final examination scores did not indicate any difference between the groups.     

The effect of a graph‐oriented computer‐assisted project‐based learning environment on argumentation skills

The purpose of this quasi‐experimental study was to explore how seventh graders in a suburban school in the United States developed argumentation skills and science knowledge in a project‐based learning environment that incorporated a graph‐oriented, computer‐assisted application. A total of 54 students (three classes) comprised this treatment condition and were engaged in a project‐based learning environment that incorporated a graph‐oriented, computer‐assisted application, whereas a total of 57 students (three classes) comprised the control condition and were engaged in a project‐based learning environment without this graph‐oriented, computer‐assisted application. Verbal collaborative argumentation was recorded and the students' post essays were collected. A random effects analysis of variance (ANOVA) was conducted and a significant difference in science knowledge about alternative energies between conditions was observed. A multivariate analysis of variance (MANOVA) was conducted and there was a significant difference in counterargument and rebuttal skills between conditions. A qualitative analysis was conducted to examine how the graph‐oriented, computer‐assisted application supported students' development of argumentation skills and affected the quality of collaborative argumentation. The difference in argumentation structure and quality of argumentation between conditions might explain a difference in science knowledge as well counterargument and rebuttal skills (argumentation) between both conditions. This study concluded that a project‐based learning environment incorporating a graph‐oriented, computer‐assisted application was effective in improving students' science knowledge and developing their scientific argumentation skills.     

Effects of traditional,blended and e‐learning on students' achievement in higher education

The study investigates the effect of e‐learning, blended learning and classroom learning on students’ achievement. Two experimental groups together with a control group from Umm Al‐Qura University in Saudi Arabia were identified randomly. To assess students’ achievement in the different groups, pre‐ and post‐achievement tests were used. The results of the study (N = 148) show that there was a statistically significant difference between the three methods in terms of students’ achievement favouring the blended learning method (n = 55) with a substantial effect size of 1.34 (Hedges’ g). No significant difference was found between the e‐learning (n = 43) and traditional learning groups (n = 50) in terms of students’ achievement and with a negligible effect size of 0.02.     

The effects of training wheels and self‐learning materials in software training

Abstract The role of software training is becoming increasingly important due to the growing variety and complexity of modern software products. This paper focuses on the effectiveness and feasibility of two different kinds of individual learners' support in software training in classroom settings. This research question was investigated by analysing 11 text‐processing courses which were conducted on the basis of a quasi‐experimental research design. Firstly, the user interface was varied, i.e. half of the courses used the regular standard user interface of the software, whereas the other half used a training wheels interface in which all irrelevant functions were blocked. Secondly, in half of the courses all instruction was given by a human tutor whereas the participants in the other half received written self‐learning material. A total of 72 university students majoring in different fields participated. Dependent measures were learning time, learning outcome, and learner satisfaction.     

The effects of individual differences and visual instructional aids on disorientation,learning performance and attitudes in a Hypermedia Learning System

Research suggests that certain visual instructional aids can reduce levels of disorientation and increase learning performance in, and positive attitudes towards, HLS for learners with specific individual differences. However, existing studies have looked at only one or two individual differences at a time, and/or considered only a small number of visual instructional aids. No study has considered the impact of the three most commonly studied individual differences – cognitive style, domain knowledge and computer experience – on learning performance, disorientation and attitudes in a HLS incorporating a full range of visual instructional aids. The study reported here addresses this shortcoming, examining the effects of, and between, these three individual differences in relation to learning performance, disorientation and attitudes in two HLS versions: one that incorporated a full set of visual instructional aids and one that did not. Significant effects were found between the three individual differences with respect to disorientation, learning performance and attitudes in the HLS that provided no instructional aids, whereas no such effects were found for the other HLS version. Analysis of the results led to a set of HLS design guidelines, presented in the paper, and the development of an agenda for future research. Limitations of the study and their implications for the generalizability of the findings are also presented.
