Background: Digital game‐based learning is gaining increased attention from both researchers and educators for improving mathematics instruction. However, the evidence for game‐based learning is mixed and research with rigorous research design and analyses are limited. Objective: Here, in a pre‐registered randomized controlled study, we investigated whether a fraction game designed collaboratively by educational experts and professional game developers may serve as a useful tool to enhance students' fraction knowledge. Methods: We assigned French fifth graders to either an experimental group who used the game (n = 110) or a control group (n = 78) who received traditional instruction on fractions. Fraction knowledge was assessed pre‐ and post‐intervention. Results: Results show that students in the active control group had superior overall fraction performance than students in the experimental group at the end of intervention. However, the game had a positive effect on decimal learning. We also found a positive relation between game performance and overall fraction knowledge scores at post‐test. Contribution: The study highlights the importance of game metrics as indicators of personalized assessment tools. Given the increased usage of games in learning mathematics and the equivocal results on the effectiveness of these games, our study also highlights the importance of pre‐registration and randomized controlled studies. Lay Description: What is already known about this topic: Digital game‐based learning (DGBL) is gaining popularity in mathematics teaching.DGBL shows potential for teaching difficult abstract concepts such as fractions.However, research evaluating DGBL for fractions is limited.

The objective of this paper is to describe gestational weight gain (GWG), to assess the applicability of the 2009 Institute of Medicine (IOM) guidelines, and to derive a GWG adequacy classification within a French cohort. We included twins from the national, prospective, population‐based JUmeaux MODe d'Accouchement (JUMODA) cohort study (2014–2015). Following the IOM approach, we selected a 'standard' population of term pregnancies with 'optimal' birthweight (≥2500 g; n = 2562). GWG adequacy (insufficient; adequate; excessive) was defined using IOM recommendations (normal body mass index [BMI]: 16.8–24.5 kg [also utilized for underweight BMI]; overweight: 14.1–22.7 kg; obese: 11.4–19.1 kg). Additionally, using the IOM approach, we determined the 25th and 75th percentiles of GWG in our standard population to create a JUMODA‐derived GWG adequacy classification. GWG and GWG adequacy were described, overall and by BMI and parity. In the JUMODA standard population of term twin livebirths with optimal birthweight, mean GWG was 16.1 kg (standard deviation 6.3). Using IOM recommendations, almost half (46.5%) of the women had insufficient and few (10.0%) had excessive GWG, with similar results regardless of BMI or parity. The 25th and 75th percentiles of GWG in the JUMODA standard population (underweight: 13–21 kg; normal weight: 13–20 kg; overweight: 11–19 kg; obese: 7–16 kg) were lower than the IOM recommendations. The IOM recommendations classified a relatively high percentage of French women as having insufficient and a low percentage as having excessive GWG. Additional research to evaluate recommendations in relation to adverse perinatal outcomes is needed to determine whether the IOM recommendations or the JUMODA‐derived classification is more appropriate for French twin gestations. Key messages: Using the 2009 Institute of Medicine (IOM) recommendations to define gestational weight gain (GWG) adequacy in our French cohort classified almost half of women as having insufficient GWG and a relatively low percentage as having excessive GWG.The USA‐derived IOM definition for adequate GWG may not apply in France or in other non‐USA, contemporary obstetric populations.Additional research in large, population‐based contemporary cohorts with prospective GWG ascertainment and assessment of GWG adequacy classifications in relation to adverse outcomes is needed to inform evidence‐based GWG recommendations for twin pregnancies.

Background: As educational digital technologies are increasingly being used in schools, past research left unanswered the question of these technologies' impact on the socioeconomic achievement gap even when equal access is guaranteed. Objectives: The objectives of the present study are to examine whether and how the socioeconomic achievement gap can be reduced through the use of computer‐assisted instruction (CAI). Methods: We addressed this issue experimentally by comparing CAI to conventional teacher‐led classroom instruction with more than 800 middle and high school students from disadvantaged and highly privileged socioeconomic backgrounds in a range of topics. Results and Conclusions: Both disadvantaged and highly privileged students taught with CAI outperformed those taught with conventional instruction, thus maintaining the socioeconomic achievement gap constant. However, we also found that disadvantaged students receiving CAI performed as well as highly privileged students receiving conventional teacher‐led instruction. Takeaways: The positive effects associated with CAI may therefore help compensate the difficulties of students with a disadvantaged background, a still neglected possibility. Lay Description: What is already known about this topic?: Socioeconomic status affects academic achievement especially in students from disadvantaged backgrounds.Inequal access to digital learning is a by‐product of socioeconomic status.Computer‐assisted instruction is known to yield positive effects on learning. What this paper adds?: It examines the effectiveness of computer‐assisted instruction on reducing the socioeconomic achievement gap when equal access to digital education is guaranteed at the school level.It shows that computer‐assisted instruction (relative to teacher‐led conventional instruction) benefited disadvantaged students and their highly privileged counterparts equally, shifting the socioeconomic achievement gap upward.However, disadvantaged students receiving CAI may reach similar performance level as their highly privileged counterparts receiving conventional instruction, thus compensating the socioeconomic achievement gap. Implications for practice and/or policy: This finding strengthens the importance of targeting teaching methods depending on students' socioeconomic characteristics to allow disadvantaged students to maximize their learning potential and chances to access to higher education.

Background: Articulatory excursion and vocal intensity are reduced in many children with dysarthria due to cerebral palsy (CP), contributing to the children's intelligibility deficits and negatively affecting their social participation. However, the effects of speech‐treatment strategies for improving intelligibility in this population are understudied, especially for children who speak languages other than English. In a cueing study on English‐speaking children with dysarthria, acoustic variables and intelligibility improved when the children were provided with cues aimed to increase articulatory excursion and vocal intensity. While French is among the top 20 most spoken languages in the world, dysarthria and its management in French‐speaking children are virtually unexplored areas of research. Information gleaned from such research is critical for providing an evidence base on which to provide treatment. Aims: To examine acoustic and perceptual changes in the speech of French‐speaking children with dysarthria, who are provided with speech cues targeting greater articulatory excursion (French translation of 'speak with your big mouth') and vocal intensity (French translation of 'speak with your strong voice'). This study investigated whether, in response to the cues, the children would make acoustic changes and listeners would perceive the children's speech as more intelligible. Methods & Procedures: Eleven children with dysarthria due to CP (six girls, five boys; ages 4;11–17;0 years; eight with spastic CP, three with dyskinetic CP) repeated pre‐recorded speech stimuli across three speaking conditions (habitual, 'big mouth' and 'strong voice'). Stimuli were sentences and contrastive words in phrases. Acoustic analyses were conducted. A total of 66 Belgian‐French listeners transcribed the children's utterances orthographically and rated their ease of understanding on a visual analogue scale at sentence and word levels. Outcomes & Results: Acoustic analyses revealed significantly longer duration in response to the big mouth cue at sentence level and in response to both the big mouth and strong voice cues at word level. Significantly higher vocal sound‐pressure levels were found following both cues at sentence and word levels. Both cues elicited significantly higher first‐formant vowel frequencies and listeners' greater ease‐of‐understanding ratings at word level. Increases in the percentage of words transcribed correctly and in sentence ease‐of‐understanding ratings, however, did not reach statistical significance. Considerable variability between children was observed. Conclusions & Implications: Speech cues targeting greater articulatory excursion and vocal intensity yield significant acoustic changes in French‐speaking children with dysarthria. However, the changes may only aid listeners' ease of understanding at word level. The significant findings and great inter‐speaker variability are generally consistent with studies on English‐speaking children with dysarthria, although changes appear more constrained in these French‐speaking children. What this paper addsWhat is already known on the subjectAccording to the only study comparing effects of speech‐cueing strategies on English‐speaking children with dysarthria, intelligibility increases when the children are provided with cues aimed to increase articulatory excursion and vocal intensity. Little is known about speech characteristics in French‐speaking children with dysarthria and no published research has explored effects of cueing strategies in this population.What this paper adds to existing knowledgeThis paper is the first study to examine the effects of speech cues on the acoustics and intelligibility of French‐speaking children with CP. It provides evidence that the children can make use of cues to modify their speech, although the changes may only aid listeners' ease of understanding at word level.What are the potential or actual clinical implications of this work?For clinicians, the findings suggest that speech cues emphasizing increasing articulatory excursion and vocal intensity show promise for improving the ease of understanding of words produced by francophone children with dysarthria, although improvements may be modest. The variability in the responses also suggests that this population may benefit from a combination of such cues to produce words that are easier to understand. [ABSTRACT FROM AUTHOR]

Many studies have demonstrated the crucial role of vocabulary in predicting reading performance in general. More recent work has indicated that one particular facet of vocabulary (its depth) is more closely related to language comprehension, especially inferential comprehension. On this basis, we developed a training application to specifically improve vocabulary depth. The objective of this study was to test the effectiveness of a mobile application designed to improve vocabulary depth. The effectiveness of this training was examined on 3rd and 4th grade children's vocabulary (breadth and depth), decoding and comprehension performances. A randomized waiting‐list control paradigm was used in which an experimental group first received the intervention during the first 4 weeks (between pretest and post‐test1), thereafter, a waiting control group received the training for the next 4 weeks (between postest1 and posttest2). Results showed that the developed application led to significant improvements in terms of vocabulary depth performance, as well as a significant transfer effect to reading comprehension. However, we did not observe such a beneficial effect on either vocabulary breadth or written word identification. These results are discussed in terms of the links between vocabulary depth and comprehension, and the opportunities the app presents for remedying language comprehension deficits in children. Lay Description: What is already known about this topic:Vocabulary is a powerful predictor of both word identification and text comprehensionVocabulary depth rather than breadth is more closely related to language comprehensionDepth of vocabulary is particularly predictive of inferencing skills What this paper adds:We develop a new training application specifically targeting vocabulary depthThe training led to significant gain in children's knowledge for the taught wordsWe also observe a transfer effect with significant improvements in reading comprehension Implications for practice and/or policy:Vocabulary depth trainings represent a good way for remedying language comprehension deficits [ABSTRACT FROM AUTHOR]

We investigated the effects of readymade versus self‐generated graphic organizers (GOs) on learning, comparing the performances of undergraduates (N = 81) tasked with learning a multimedia document. This document was either presented on its own (control group), with a readymade GO, or with a blank GO that students had to fill in either before or during the learning of the document. In line with previous research, adding a readymade GO increased students' memorization and transfer scores, compared with controls. By displaying the main ideas in the text and their hierarchical relations, GOs act as visual aids to learning. Results showed that self‐generating a GO was no more beneficial than viewing a readymade GO when students were placed in a dual‐task situation (generation + learning). However, when the students' information processing was guided by sequencing these tasks (generation then learning), they outperformed the control and readymade groups on memorization and comprehension. Lay Description: What is already known about this topic: Graphic organizers (GOs) consist in visual displays showing the main ideas of a text and their interrelations.Adding GOs to pedagogical document have been shown to improve students' learning.However, self‐generating GOs has been proven to be detrimental for learning in several studies. What this paper adds: In previous studies, self‐generation of graphic organizers (GOs) have often been carried out while learning, however this task should be separated from the learning task.In the present study, students' learning performances increased when the self‐generated task was separated from the learning task compared to a condition with a readymade GO.These benefits on learning were not observed when the self‐generated activity was not guided. Implications for practitioners: Graphic organizers gathering all the key elements of a multimedia document and highlighting the structure of this document should be used in order to increase students' learning.Students should not be placed in double‐task situation when learning from a pedagogical document.In‐task guidance should be provided when self‐generative tasks are performed.

Breastfeeding is recommended until 6 months of age, but a wide range of infant formula is available for nonbreastfed or partially breastfed infants. Our aim was to describe infant formula selection and to examine social- and health-related factors associated with this selection. Analyses were based on 13,291 infants from the French national birth cohort Etude Longitudinale Française depuis l'Enfance. Infant diet was assessed at Month 2 by phone interview and monthly from Months 3 to 10 via internet/paper questionnaires. Infant formulas were categorized in 6 groups: extensively or partially hydrolysed, regular with or without prebiotics/probiotics, and thickened with or without prebiotics/probiotics. Associations between type of infant formula used at 2 months and family or infant characteristics were assessed by multinomial logistic regressions. At Month 2, 58.1% of formula-fed infants were fed with formula enriched in prebiotics/probiotics, 31.5% with thickened formula, and 1.4% with extensively hydrolysed formula. The proportion of formula-fed infants increased regularly, but the type of infant formula used was fairly stable between 2 and 10 months. At Month 2, extensively hydrolysed formulas were more likely to be used in infants with diarrhoea or regurgitation problems. Partially hydrolysed formulas were more often used in families with high income, with a history of allergy, or with infants with regurgitation issues. Thickened formulas were used more with boys, preterm infants, infants with regurgitation issues, or in cases of early maternal return to work. The main factors related to the selection of infant formula were family and infant health-related ones. [ABSTRACT FROM AUTHOR]
