Students’ choice of animated pedagogical agents in science learning: A test of the similarity-attraction hypothesis on gender and ethnicity

College students learned about science with a multimedia program. One group (choice or C) chose to learn with or without an animated pedagogical agent (APA) representing a male or female of five different ethnicities. Another group (no-choice or NC) was assigned an APA by the system. All participants in C group chose to learn with APAs and students of color chose significantly more same-ethnicity APAs than White American students. A significant interaction between choice and ethnic similarity factors revealed that group C produced lower retention, transfer, and program ratings when learning with same-ethnicity rather than different-ethnicity APAs. Results support an interference hypothesis for students who choose to learn with same-ethnicity APAs.     

Cognitive support for learning computer-based tasks using animated demonstration

This study investigated the influence of cognitive support for learning computer-based tasks using animated demonstration (AD) on instructional efficiency. Cognitive support included (1) segmentation and learner control introducing interactive devices that allow content sequencing through a navigational menu, and content pacing through stop and play buttons along with a slide bar for fast forward and rewind; (2) presentation modality and (3) a hybrid approach using a combined format of ADs with static graphics. Instructional efficiency was a combined effect of time-on-task during the learning phase and test performance. Time-on-task was included as a measurement to determine whether this would provide an alternative explanation for the benefits of learner control. Three learner-paced conditions with different types of cognitive support were developed, whereas a system-paced format, created without additional cognitive support, was used as a control condition. The learning task of this study was using graphic vector-based software Bezier tools to trace a cartoon. The results tended to suggest that the combination of different types of cognitive support (i.e. presenting the accompanying explanations as written captions to the learner-paced AD in visual-only instruction or combining learner-paced AD with static graphics in dual-modality instruction) had a positive effect, while learner pacing alone had not a significant positive effect.

To guide or not to guide: issues in the sequencing of pedagogical structure in computational model-based learning

This research explores issues related to the sequencing of structure that is provided as pedagogical guidance. A study was conducted that involved grade 10 students in Singapore as they learned concepts about electricity using four NetLogo Investigations of Electricity agent-based models. It was found that the low-to-high structure learning sequences group participants scored significantly higher on the posttest assessments of conceptual and procedural understanding of electricity concepts, whereas the high-to-high structure learning sequences showed no significant changes from pretest to posttest. The implications of these findings are discussed with respect to other research into the sequencing and design of pedagogical structure and guidance in the literature.     

Individual differences in an English learning achievement system: gaming flow experience,gender differences and learning motivation

Despite the growing interest in digital game-based learning (DGBL), there has been a lack of attention paid to the effects of individual differences, such as gaming flow experience and gender differences, in a reward-based achievement system. To this end, this study developed an achievement system with a reward mechanism to facilitate English learning. This study investigated how individuals’ gaming flow experience levels affected their levels of learning motivation, and whether any gender differences existed in gaming flow experience and learning motivation while engaging in the achievement system. The results showed that gaming flow experience significantly predicted learning motivation, whereby the students with high gaming flow experience were six times more likely to have high learning motivation than those with low gaming flow experience. Subsequent analysis showed that the female students had significantly higher gaming flow than the male students, but the male and female students showed similar learning motivation. Furthermore, the results indicated that the male students achieved more interactive rewards than the female students, but no significant differences were found in the male and female students’ achievement of other types of rewards. Based on these findings, the authors contribute to the literature by developing a framework which can be applied to support designers to accommodate individual differences in DGBL.     

Feedback processes in multimedia language learning software

Feedback has been one of the important elements of learning and teaching theories and still pervades the literature and instructional models, especially computer and web-based ones. However, the mechanisms about feedback dominating the fundamentals of all the instructional models designed for self-learning have changed considerably with the interactive multimedia technology of today, which have recourse to a wider range of potential in terms of use and functionality. The study intends to indicate that feedback has double functions： On one hand, it has classic ＂triad＂ functions--feedback as motivator, reinforcement and information--in terms of computer-assisted instruction and, on the other hand, as it is emphasized in this study, it forms the core and maintains the continuity of the machine-learner interaction in multimedia software designed today. This work, originally a discussion paper, consists of a review of the related literature and analyses of the software programs designed for teaching French to adults as foreign language in French module of Multimedia Language Learning Centre at Charles-de-Gaulle University （Lille-France）.     

Active teaching to manage course difficulty and learning motivation

Given the recent reported common occurrence of mediocre or substandard academic performance by students in colleges and universities, it has become essential to identify pedagogical factors that might lessen or reverse this trend. Kolb’s experiential learning, Pintrich’s student learning motivation, and cognitive load theories were used as a framework to assess active teaching moderation of the effects of course difficulty on course performance and learning motivation. Hierarchical ordinary least squares (OLS) regression was used to analyse the data. Research subjects were recruited from a medium-sized historically Black college and university (HBCU) students enrolled in STEM (science, technology, engineering, and mathematics) and Business (i.e. management, economics, or accounting) classes. Active teaching was a positive predictor of course grade and learning motivation. Course difficulty was a negative predictor of course grade. Interaction analysis revealed that increases in active teaching reduced (i.e. moderated) the negative relationship between course difficulty on both course grade and learning motivation. Overall, the findings suggest that student learning outcomes are certainly a function of pedagogy (e.g. active teaching), psychological/affective (e.g. learning motivation), and learning content complexity. Active teaching environments should (1) address both cognitive load and emotional responses attributed to difficult coursework, and (2) provide efficacy building opportunities during instructional delivery.

Using conceptual questions to promote motivation and learning in physics lectures

In the last years, science courses in higher education (HE) have been facing some problems, namely the lack of students’ motivation, the number of students’ failures and drop outs, particular in physics courses. The most probable reason, which has been mentioned in current science education research in HE, is that the level of interaction between teachers and learners in formal instructional settings is very low. In this paper, we describe changes that were introduced in lectures towards the promotion of active learning and analyse its effects in the classroom environment. The introduction of conceptual questions and peer instruction seems to motivate students in the class and help them engage in the learning process. These strategies have been used in the first year of an introductory physics course for engineering students in two different Portuguese HE institutions. The data were collected through questionnaires and student interviews.     

The effects of affective pedagogical agent in multimedia learning environments: A meta-analysis

Affective pedagogical agent (PA) is an image of a character embedded in multimedia lessons with the ability to influence learners' affective experiences and learning performance. Prior studies on the effects of affective PA have shown inconsistent findings. In this study, we conducted four separate meta-analyses to address whether adding an affective PA to multimedia lessons can increase learners' retention performance, transfer performance, positive emotions, and intrinsic motivation, and to explore several moderators that may have contributed to the inconsistencies of previous studies. The research framework mainly includes introducing the concept of affective PA, reviewing research on the impact of affective PA on learning performance, emotions, and motivation, analyzing the moderators that may affect the effects of affective PA, performing a meta-analysis, and discussing the results based on the findings of the meta-analysis. We found 36 articles met the inclusion criteria. The results of the meta-analysis indicated that affective PA could increase learners’ positive emotions (k = 25, g = 0.26), improve intrinsic motivation (k = 26, g = 0.26), and facilitate learning performance (retention: k = 35, g = 0.26; transfer: k = 45, g = 0.34). Furthermore, moderator analysis found that affective PA characteristics (i.e., appearance, the number of emotional cues, and body movement) and learning materials characteristics (i.e., subject domain, pacing of presentation) moderated the effects of affective PA. We discussed these findings from different theoretical perspectives. In general, affective PA could help students be happier and more motivated to learn in multimedia learning environments.
