Effects of anxiety levels on learning performance and gaming performance in digital game‐based learning

Anxiety plays an influential role in foreign language learning. However, a lack of attention was paid to examining the effects of anxiety levels on learning performance and gaming performance in digital game‐based learning. To this end, this study developed a game‐based English learning system and investigated how different levels of anxiety affected learners' learning performance and gaming performance. A quasi‐experiment was conducted in an elementary school. The results showed that high‐anxiety learners performed worse than low‐anxiety learners in speaking, word/sentence match, and overall learning performance. However, they performed similarly in listening performance. Moreover, the results showed that high‐ and low‐anxiety learners demonstrated a similar level of gaming performance. A subsequent analysis showed that significant correlations existed between learning performance and gaming performance for learners with high anxiety whereas such positive correlations were rarely found for learners with low anxiety, indicating that high‐anxiety learners' learning performance could be fostered by their gaming performance. The findings suggested that digital game‐based learning was particularly beneficial to high‐anxiety learners, whose gaming performance was a facilitative factor of their learning performance.

The effects of GBL and learning styles on Chinese idiom by using TUI device

This study investigated how the integration of a game‐based learning strategy and a tangible user interface (TUI) device improves the learning achievement of fifth‐grade students in studying Chinese idioms. By using the sifting, and sorting, features of Sifteo Cubes, learners, via a gaming situation, manually composed the cubes to the correct idioms, and the system also provided the origins of the idioms, facilitating meaningful learning. A quasi‐experimental non‐equivalent control‐group design was conducted. Both the experimental and control groups were administered a pre‐test and post‐test, the Idiom Learning Performance Test (ILPT), to investigate the variations between the treatment and groups. Furthermore, the Index of Learning Style for Youth (ILSY) survey was administered to determine how different learning styles and learning strategies affect learning achievement. The results showed that, after the CILS was used, the post‐test scores were significantly higher than the pre‐test scores in the experimental group. In addition, the post‐test scores of active and visual learners were higher than the pre‐test scores, and were significantly higher than reflective and verbal learners. The results suggested that the CILS is suitable for active and visual learners. Recommendations for using the CILS and Sifteo Cubes in instruction and further direction research are provided.     

Kes Sesi: A mobile game designed to improve kindergarteners' recognition of letter sounds

Learning letters is an important area of language learning, conducive to the beginning of reading and writing. Indeed, today's generation prefers to learn through digital games rather than through formal teaching processes. Inspired by this need, the researcher designed this study (a) to test the effectiveness of an instructional digital game, “Kes Sesi,” designed to teach letter recognition skills and (b) to briefly present its instructional development process, which was based on the ADDIE model. This was a quasi‐experimental study with two treatment groups and a control group involving 87 kindergarteners. Treatment groups played the game for 12–6 weeks for learning, 6 weeks for practice. The control group continued with its regular class activities. One treatment group played the game based on predefined sound categorization, the other without any categorization. A test on children's sound recognition abilities was administered three times as a pretest, a midtest, and a posttest. The treatment groups performed significantly better than the control group. The game enhanced the kindergarteners' ability to practice uncategorized content while it enhanced their ability to learn categorized content. The results are promising in that Kes Sesi can be useful in self‐supported learning contexts with little adult input and with minimum outside interference.

Expository multimedia comprehension in E-learning: Presentation format,verbal ability and working memory capacity

Most of the studies establishing factors affecting digital text and multimedia comprehension have been conducted in controlled conditions. The present study sought to test and extend the modality and seductive details effects, and the role of verbal ability and working memory capacity, to a remote, self-paced, E-learning scenario. Two hundred and thirteen first-year undergraduates read or watched videos about scientific expository content in three formats: digital text (written expository texts, navigated in seven screens), presentation video (audio explanation, with written keywords), and presentation video with dynamic decorative images (audio explanation, written keywords, and dynamic decorative and irrelevant images). In a face-to-face session, they completed working memory and verbal ability tests. Comprehension performance was similar for the three conditions. For the multimedia videos with dynamic decorative irrelevant images, comprehension depended on working memory capacity. Verbal ability was relevant for both expository text and videos.     

Using eye movement modelling examples to guide visual attention and foster cognitive performance: A meta-analysis

Eye movement modelling examples (EMME) are computer-based videos displaying the visualized eye gaze behaviour of a domain expert person (model) while carefully executing the learning or problem-solving task. The role of EMME in promoting cognitive performance (i.e., final scores of learning outcome or problem solving) has been questioned due to the mixed findings from empirical studies. This study tested the effects of EMME on attention guidance and cognitive performance by means of meta-analytic procedures. Data for both experimental and control groups and both posttest and pretest were extracted to calculate the effect sizes. The EMME group was treated as the experimental group and the non-EMME group was treated as the control group. Twenty-five independent articles were included. The overall analysis showed a significant effect of EMME on time to first fixation (d = −0.83), fixation duration (d = 0.74), as well as cognitive performance (d = 0.43), but not on fixation count, indicating that using EMME not only helped learners attend faster and longer to the task-relevant elements, but also fostered their final cognitive performance. Interestingly, task type significantly moderated the effect of EMME on cognitive performance. Moderation analyses showed that EMME was beneficial to learners' performance when non-procedural tasks (rather than procedural tasks) were used. These findings show contributions for future research as well as practical application in the field of computers and learning regarding videos displaying a model's visualized eye gaze behaviour.

The effects of gender,flow and video game experience on combat identification training

Abstract

The present study examined the effects of gender, video game experience (VGE), and flow state on multiple indices of combat identification (CID) performance. Individuals were trained on six combat vehicles in a simulation, presented through either a stereoscopic or non-stereoscopic display. Participants then reported flow state, VGE and were tested on their ability to discriminate friend vs. foe and identify both pictures and videos of the trained vehicles. The effect of stereoscopy was not significant. There was an effect of gender across three dependent measures. For the two picture-based measures, the effect of gender was mediated by VGE. Additionally, the effect of gender was moderated by flow state on the identification measures. Overall, the study suggests that gender differences may be overcome by VGE and by achieving flow state. Selection based on these individual differences may be useful for future military simulation.

Practitioner Summary: This work investigates the effect of gender, VGE and flow state on CID performance. For three measures of performance, there was a main effect of gender. Gender was mediated by previous VGE on two measures, and gender was moderated by flow state on two measures.     

Measuring working memory load effects on electrophysiological markers of attention orienting during a simulated drive

Intersection accidents result in a significant proportion of road fatalities, and attention allocation likely plays a role. Attention allocation may depend on (limited) working memory (WM) capacity. Driving is often combined with tasks increasing WM load, consequently impairing attention orienting. This study (n = 22) investigated WM load effects on event-related potentials (ERPs) related to attention orienting. A simulated driving environment allowed continuous lane-keeping measurement. Participants were asked to orient attention covertly towards the side indicated by an arrow, and to respond only to moving cars appearing on the attended side by pressing a button. WM load was manipulated using a concurrent memory task. ERPs showed typical attentional modulation (cue: contralateral negativity, LDAP; car: N1, P1, SN and P3) under low and high load conditions. With increased WM load, lane-keeping performance improved, while dual task performance degraded (memory task: increased error rate; orienting task: increased false alarms, smaller P3).

Practitioner Summary: Intersection driver-support systems aim to improve traffic safety and flow. However, in-vehicle systems induce WM load, increasing the tendency to yield. Traffic flow reduces if drivers stop at inappropriate times, reducing the effectiveness of systems. Consequently, driver-support systems could include WM load measurement during driving in the development phase.     

Supporting conceptual understanding of the associative and distributive properties through digital gameplay

There has been a steady rise in the support for games as learning environments. This support is largely based on the strong levels of engagement and motivation observed during gameplay. What has proven difficult is the ability to consistently design and develop learning games that are both engaging and educationally viable. Those in the game‐based learning community contend the solution is to tightly integrate instructional objective(s) within the game's mechanics. In order to investigate whether or not intrinsic integration would aid in game design, an experimental study was conducted with 111 fourth and fifth graders in which three versions of a game were designed in order to determine which approach would have a more significant impact on conceptual understanding of the associative and distributive properties. It was found that those who played the intrinsic version of the game (properties mapped to game mechanics) had significant learning gains compared with those who played the extrinsic version. Perceptions of the game are also discussed, along with future directions.     

Micro‐adaptivity: protecting immersion in didactically adaptive digital educational games

The idea of utilizing the rich potential of today's computer games for educational purposes excites educators, scientists and technicians. Despite the significant hype over digital game‐based learning, the genre is currently at an early stage. One of the most significant challenges for research and development in this area is establishing intelligent mechanisms to support and guide the learner, and to realize a subtle balance between learning and gaming, and between challenge and ability on an individual basis. In contrast to traditional approaches of adaptive and intelligent tutoring, the key advantage of games is their immersive and motivational potential. Because of this, the psycho‐pedagogical and didactic measures must not compromise gaming experience, immersion and flow. In the present paper, we introduce the concept of micro‐adaptivity, an approach that enables an educational game to intelligently monitor and interpret the learner's behaviour in the game's virtual world in a non‐invasive manner. On this basis, micro‐adaptivity enables interventions, support, guidance or feedback in a meaningful, personalized way that is embedded in the game's flow. The presented approach was developed in the context of the European Enhanced Learning Experience and Knowledge TRAnsfer project. This project also realized a prototype game, demonstrating the capabilities, strengths and weaknesses of micro‐adaptivity.

The effects of participation,performance, and interest in a game‐based writing environment

We have observed that many computer‐supported writing environments based on pedagogical strategies have only been designed to incorporate the cognitive aspects, but motivational aspects should also be included. Hence, we theorize that integrating game‐based learning into the writing environment may be a practical approach that can facilitate student participation, not only helping students learn how to write, but also sustaining their willingness to write. In this study, we investigate the effects of the game‐based writing environment on improving students' participation, performance, and interest in writing. An experiment was conducted to compare the effectiveness of 2 approaches to writing in language arts at an elementary school. Two hundred forty‐five third grade students participated in the experiment over a period of 1 year. One hundred thirty‐nine students were assigned to an experimental group and learned with a game‐based writing environment, and 106 students were in the contrast group and learned with an online writing environment. The empirical results show that the game‐based writing environment can effectively promote students' writing participation, writing performance, interest in writing, as well as their perceptions of the use of educational self‐management games. Some implications of the experimental results are also discussed.     

The influence of user expertise and prototype fidelity in usability tests

An empirical study examined the impact of user expertise and prototype fidelity on the outcomes of a usability test. User expertise (expert vs. novice) and prototype fidelity (paper prototype, 3D mock-up, and fully operational appliance) were manipulated as independent variables in a 2 × 3 between-subjects design. Employing a floor scrubber as a model product, 48 users carried out several cleaning tasks. Usability problems identified by participants were recorded. Furthermore, performance, system management strategies and perceived usability were measured. The results showed that experts reported more usability problems than novices but these were considered to be less severe than those reported by novices. Reduced fidelity prototypes were generally suitable to predict product usability of the real appliance. The implications for the running of usability tests are specific to the fidelity of the prototype.     

Investigating an application of speech‐to‐text recognition: a study on visual attention and learning behaviour

One major drawback of previous research on speech‐to‐text recognition (STR) is that most findings showing the effectiveness of STR for learning were based upon subjective evidence. Very few studies have used eye‐tracking techniques to investigate visual attention of students on STR‐generated text. Furthermore, not much attention was paid to learning differences, such as learning ability, learning style preferences and gender, to use STR texts. Therefore, this study carried out one experiment. Firstly, participants' visual attention on STR‐generated text was investigated by employing eye‐tracking technique. Secondly, how differently effective STR‐generated texts can be to influence participants' learning achievement was tested. Thirdly, this study compared visual attention and learning behaviour with the different characteristics of participants, such as learning ability, learning style preferences and gender, to use STR‐generated texts. Finally, this study explored students' perceptions regarding usefulness of STR‐generated texts for learning. This paper discusses results, research findings and implications along with conclusions and several suggestions for future development and research.
