Responsiveness to a game-based intervention to enhance reading efficiency in first graders

In the present study, a 5-week tablet-based word reading efficiency game intervention (Reading Turbo) was integrated in a comprehensive phonics-based reading curriculum. The aims of the study were to examine whether the game would advance children's word reading efficiency, and to determine the extent to which pre-reading capacities and in-game mechanisms could explain individual variation in responsiveness to the game. To do so, word reading efficiency scores of first graders in an intervention group (n = 132) and a control group that continued with the usual reading curriculum (n = 118) were compared prior to, directly after, and 2 months after the 5-week intervention period. Individual variation in responsiveness was examined by relating reading precursors (i.e., phonological awareness, letter efficiency, rapid automatized naming (RAN), and verbal working memory) measured at the onset of the intervention, and in-game accuracy and efficiency to word reading efficiency outcomes in untrained words. Results indicated that playing the word reading game significantly enhanced first graders' word reading efficiency directly after the intervention, but the effect was no longer significant 2 months after the intervention. With respect to individual variation in game responsiveness, it was found that phonological awareness, letter efficiency, and verbal working memory predicted responsiveness to the game via in-game accuracy. In addition, phonological awareness and RAN predicted responsiveness to the game via in-game efficiency, and letter efficiency and verbal working memory were directly related to responsiveness. The effectiveness of the word reading game thus differentiated between children with higher and lower pre-reading capacities, and operated via in-game child affordances.     

The effectiveness of adaptive difficulty adjustments on students' motivation and learning in an educational computer game

Computer games that adaptively adjust difficulty are used to continuously challenge players according to their abilities. The adjustment of difficulty occurs automatically in response to a game's ongoing assessment of a player's performance. This approach to difficulty adjustment is likely to be of value in educational computer games as a means of scaffolding learning for students. However, there is limited research evaluating the effectiveness of educational computer games with adaptive difficulty adjustment when compared to non-adaptive difficulty adjustment. To expand on this research a quasi-experimental study was designed to isolate the impact of the difficulty adjustment game element on motivation and learning. A total of 234 secondary school students were allocated to one of three activities involving learning about Spanish cognates: an adaptive difficulty adjustment game, an incremental difficulty adjustment game that was non-adaptive, and a written activity. The three learning activities were designed following the same learning and motivation theories. The two games were identical apart from the difficulty adjustment mechanism. The results for motivation indicated that all students experienced high levels and there was no significant difference between the three learning activities. The pre- and post-tests results for learning indicated that significantly higher learning outcomes were achieved by students who played the adaptive game. Analysis of a game log recording the correctness of students' responses indicated that the adaptive difficulty adjustment game, in contrast to the non-adaptive incremental difficulty adjustment game, provided a scaffolding structure to enhance student learning.     

The effects of keyword cues and 3R strategy on children's e‐book reading

Various studies have found that electronic books (e‐books) promote learning, but few works have examined the use of e‐books along with an adaptive reading strategy for children. The current study implemented a method to extract keyword cues from e‐books to support e‐book reading with the read, recite and review (3R) strategy, and then examined the impact of this on children's reading performance. A pilot work recruited 76 first‐graders, developed the related reading tests and questionnaires. These were later used in assessing the effects of different interventions on the reading performances and perspectives of 74 first‐graders in the main study. Based on the findings of this work, the 3R strategy can be used as an effective approach to guide children's reading with e‐books. In addition, the use of keyword cues incorporated with retrieval practice can provide support with regard to Chinese characters and phonetic information in order to aid children's memorization of the story, thus promoting both phonological awareness and reading comprehension.     

Early reading intervention by means of a multicomponent reading game

This study examined the effects of an intervention with a multicomponent reading game on the development of reading skills in 60 Dutch primary school children with special educational needs. The game contains evidence‐based reading exercises and is based on principles of applied gaming. Using a multiple baseline approach, we tested children's word, pseudoword and text reading fluency, as well as their reading motivation, at three test occasions. The results indicated that the short intervention (9 × 15 min) enhanced children's pseudoword reading fluency as well as their text reading fluency. Interestingly, the early intervention group showed a sustained intervention effect (i.e., also during retention), which shows that using this reading game has a long‐term effect on early text reading development. Intervention did not affect reading motivation, which suggests that the multicomponent reading game can be used to facilitate early reading development without compromising reading motivation.     

Adaptive retrieval practice with multiple-choice questions in the university classroom

Retrieval practice promotes retention more than restudying (i.e., the testing effect) and is applied to many educational settings. However, little research has investigated means to enhance this effect in educational settings. Theoretical accounts assume retrieval practice to be the most effective whenever retrieval is difficult but successful. Therefore, we developed a novel retrieval practice procedure, which adapts to learners' abilities and can be applied irrespective of learning content. This adaptive procedure aims to make retrieval gradually easier whenever students provide an incorrect answer. In a field experiment, students read book chapters as part of a weekly university course. In three consecutive weeks, they then practiced reading assignments by (a) adaptive testing, (b) non-adaptive testing and (c) restudy. In Week 4, a surprise criterial test took place. Restudy outperformed both testing conditions, whereas adaptive testing performed equally well as non-adaptive testing. However, exploratory analyses revealed that with increasing retention intervals, the superiority of restudy disappeared. Furthermore, whenever participants fully read the assignments and retention intervals increased, adaptive testing outperformed non-adaptive testing. In sum, adaptive retrieval practice did not prove to be generally superior, but retention interval and students' preparation for class might be conditions rendering adaptive retrieval useful in educational settings.     

Long-term effects of computer training of phonological awareness in kindergarten

The present study examined the long-term effects of a computer intervention for the development of phonological awareness in Dutch kindergartners. Native Dutch and immigrant children worked with the software 15 min/week during one school year. Following a pretest – interim test – post-test – retention test design, the effects on rhyming, phonemic segmentation, auditory blending, and grapheme knowledge were assessed. The intervention showed significant immediate effects on rhyming and grapheme knowledge. The time spent on the computer games also correlated with the learning gains for the experimental group. In the first grade, retention effects were demonstrated after 4 months of formal reading education.     

Do ABC eBooks boost engagement and learning in preschoolers? An experimental study comparing eBooks with paper ABC and storybook controls

Alphabet books are an important instructional text used in early education. Advances in mobile technology have led to alphabet books of an electronic format with accompanying sound, animations, and interactive hot spots. This study investigates the differential effectiveness of paper alphabet books and alphabet eBooks in training alphabetic knowledge in 4-year-olds. Three groups of approximately 30 children were assigned to one of three conditions: paper alphabet book, alphabet eBook, or storybook control. Book reading sessions composed of three to four children were run twice a week over eight weeks, with child-book behaviours coded at each session. Measures of early reading ability were collected pre and post-intervention. Children in all conditions improved over time in emergent literacy but no significant differences between conditions were found. Children using paper alphabet books were more likely to say letter names, and their time oriented to the books predicted post-test letter-name and phonological awareness after controlling for pre-test scores. In contrast, time oriented to the alphabet eBooks made no prediction to post-test sores.     

Development of a contextual decision-making game for improving students' learning performance in a health education course

Heath education is an important component of the curriculum for fostering children's correct health knowledge and good daily life habits. However, educators have indicated that most children might fail to realize the importance and meaning of health education content owing to the lack of authentic scenarios and daily life experience. With the advancement of computer technologies, researchers have tried to develop multimedia learning content in order to improve students' learning performance. Among various technology-enhanced learning alternatives, digital game-based learning has been recognized as a highly potential approach to motivating students. However, several previous studies have indicated that, without properly incorporating learning content into game scenarios, the effectiveness of digital game-based learning might not be as good as expected in comparison with conventional technology-enhanced learning. In this study, a contextual digital game was developed for improving students' learning performance in an elementary school health education course. A quasi experiment was conducted to evaluate the effectiveness of the proposed approach by situating the experimental group in the game-based learning scenario and the control group to learn with conventional e-books. The experimental results showed that the proposed approach not only improved the students' learning motivation, but also their learning achievement and problem-solving competences. Moreover, the significant two-way interaction suggested that the contextual game-based learning approach benefited the higher motivation students more than the lower motivation ones in terms of the advanced knowledge, showing the importance and potential of applying contextual games to health education activities.     

Connecting the dots: Understanding the interrelated impacts of type,quality and children's awareness of design features and the mathematics content learning goals in digital math games and related learning outcomes

This study focused on an examination of how type, quality and children's awareness of design features in digital math games, along with an awareness of the mathematics goals of the game, were related to learning outcomes. We conducted a parallel conversion mixed methods study with 45 students in Grades 3 and 4 (ages 9–10). Students participated in clinical interviews using three digital math games. The results suggest a moderated mediation relationship in which the quality of the design features moderated the mediating impact of children's awareness of the game's design features, specifically when the child was aware of the mathematics content learning goal (MCLG) of the game. These findings show how important it is that design features are of high quality in a digital math game, and how this is intertwined with children's awareness of the features and the MCLG. When these variables intertwined in just the right way, the interactions between the children and the digital math game afforded mathematical learning growth.     

The effect of text messaging on 9‐ and 10‐year‐old children's reading,spelling and phonological processing skills

This paper reports on an intervention study that considered the impact of text messaging on 9‐ to 10‐year‐old children's literacy skills. One hundred and fourteen children who had never owned a mobile phone before were recruited and randomly allocated to either the intervention or control conditions. All children were pre‐ and post‐tested on a range of reading, spelling and phonological awareness measures. Children in the intervention group were given access to a mobile phone (enabled for text messaging only) for weekends and during half‐term break for a 10‐week period. It was found that there were no significant differences between the two groups of children in terms of their literacy attainment during that period. However, within the mobile phone group, there was evidence that use of text abbreviations was positively related to gains in literacy skills. Moreover, after controlling for individual differences in IQ, and the children's performance at pre‐test, textism usage was able to account for a significant amount of variance in post‐test spelling scores. These results show that text messaging does not adversely affect the development of literacy skills within this age group, and that the children's use of textisms when text messaging is positively related to improvement in literacy skills, especially spelling.     

The learning value of computer-based instruction of early reading skills

Abstract This study examined the unique contribution of computer-based instruction when compared with more conventional modes of instruction (i.e. teacher instruction with textbooks) to early reading skills acquisition, as well as the effects of specific features of computer technology on early reading skills performance. Forty-six pre-school children (aged 5–6), at high risk for learning disabilities, participated in the study. They were assigned to one of three study groups that received different treatments. Three dependent variables were defined, i.e. children's phonological awareness, word recognition and letter recognition skills measured prior and after the treatment. Results clearly indicated that children at high risk who received the reading intervention program with computer materials significantly improved their phonological awareness, word recognition, and letter naming skills relative to their peers who received a reading intervention program with only printed materials and those who received no formal reading intervention program. The results are discussed in detail, with reference to the features of the computer-based materials that contributed to the acquisition of critical early reading skills.     

A mobile game as a support tool for children with severe difficulties in reading and spelling

We used a randomized controlled trial to investigate if a mobile game, GraphoLearn (GL), could effectively support the learning of first graders (N = 70), who have severe difficulties in reading and spelling. We studied the effects of two versions of the game: GL Reading, which focused on training letter-sound correspondence and word reading; and GL Spelling, which included additional training in phonological skills and spelling. During the spring of first grade, the children trained with tablet computers which they could carry with them during the six-week intervention. The average exposure time to training was 5 hr 44 min. The results revealed no differences in the development of reading or spelling skills between GL players and the control group. However, pre-training self-efficacy moderated the effect among GL Reading players: children with high self-efficacy developed more than the control group in word reading fluency, whereas children with low self-efficacy developed less than the control group in spelling.     

Individual characteristics and computer self-efficacy in secondary education teachers to integrate technology in educational practice

The development of modern technologies and their extension to every domain of our daily life nowadays is an indisputable fact. The widespread use of computers renders training in these technologies necessary. Consequently, computers were soon introduced into the Greek educational system. Factors related to the nature of the teacher’s personality, such as computer self-efficacy, self-concept, attitudes, motivation and needs are considered crucial to the integration and development of modern technologies in education. This study examines the relationship between individual characteristics of secondary school teachers and computer self-efficacy as well as teacher prospects with regard to modern technologies.     

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.     

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.     

Children's engagement during digital game-based learning of reading: The effects of time,rewards, and challenge

This study investigated the effects of two game features (the level of challenge and the reward system) on first and second graders' engagement during digital game-based learning of reading. We were particularly interested in determining how well these features managed to maintain children's engagement over the 8-week training period. The children (N = 138) used GraphoGame, a web-based game training letter–sound connections, at home under the supervision of parents. Data regarding the children's gaming and engagement were stored on the GraphoGame online server. A 2 × 2 factorial design was used to investigate the effects of the level of challenge (high challenge vs. high success) and the presence of the reward system (present vs. absent). Children's engagement was measured by session frequency and duration and through an in-game self-report survey that was presented at the end of the each session. According to the results, the children enjoyed GraphoGame but used it less frequently than expected. The reward system seemed to encourage the children to play longer sessions at the beginning of the training period, but this effect vanished after a few sessions. The level of challenge had no significant effect on children's engagement. The results suggest a need to investigate further the effectiveness of various game features in maintaining learner's engagement until the goals set for learning are achieved.     

The role of Persian-language word exercise games in improving spelling of students with dyslexia: Word exercise games in improving spelling

Children with dyslexia have reduced sensitivity to phonological sounds and words, and this deficiency in lexical processing causes many problems for them. Word exercise games based on phonological awareness have emphasized the mistakes of students with dyslexia, attempting to help children avoid these mistakes. This study was conducted to investigate the effect of Persian-language word exercise games on the spelling of students with dyslexia. The design of the present study was quasi-experimental, with a pretest and posttest of an experimental group and a control group. Participants were 30 students with dyslexia from second grade to fifth grade in elementary schools in Bojnord, who completed the spelling test as a pretest and posttest. The experimental group played eleven 40-min sessions of word exercise games. The results showed that the word exercise programme improved the spelling of the children with dyslexia. This suggests that basing training on the phonological mistakes of students with dyslexia and using the word exercise games can improve their spelling.     

Strategic best-response learning in multiagent systems

We present a novel and uniform formulation of the problem of reinforcement learning against bounded memory adaptive adversaries in repeated games, and the methodologies to accomplish learning in this novel framework. First we delineate a novel strategic definition of best response that optimises rewards over multiple steps, as opposed to the notion of tactical best response in game theory. We show that the problem of learning a strategic best response reduces to that of learning an optimal policy in a Markov Decision Process (MDP). We deal with both finite and infinite horizon versions of this problem. We adapt an existing Monte Carlo based algorithm for learning optimal policies in such MDPs over finite horizon, in polynomial time. We show that this new efficient algorithm can obtain higher average rewards than a previously known efficient algorithm against some opponents in the contract game. Though this improvement comes at the cost of increased domain knowledge, simple experiments in the Prisoner's Dilemma, and coordination games show that even when no extra domain knowledge (besides that an upper bound on the opponent's memory size is known) is assumed, the error can still be small. We also experiment with a general infinite-horizon learner (using function-approximation to tackle the complexity of history space) against a greedy bounded memory opponent and show that while it can create and exploit opportunities of mutual cooperation in the Prisoner's Dilemma game, it is cautious enough to ensure minimax payoffs in the Rock–Scissors–Paper game.     

Structurally noise resistant classifier for multi-modal person verification

In this letter we propose a piece-wise linear (PL) classifier for use as the decision stage in a two-modal verification system, comprised of a face and a speech expert. The classifier utilizes a fixed decision boundary that has been specifically designed to account for the effects of noisy audio conditions. Experimental results on the VidTIMIT database show that in clean conditions, the proposed classifier is outperformed by a traditional weighted summation decision stage (using both fixed and adaptive weights). Using white Gaussian noise to corrupt the audio data resulted in the PL classifier obtaining better performance than the fixed approach and similar performance to the adaptive approach. Using a more realistic noise type, namely “operations room” noise from the NOISEX-92 corpus, resulted in the PL classifier obtaining better performance than both the fixed and adaptive approaches. The better results in this case stem from the PL classifier not making a direct assumption about the type of noise that causes the mismatch between training and testing conditions (unlike the adaptive approach). Moreover, the PL classifier has the advantage of having a fixed (non-adaptive, thus simpler) structure.
