SummaryA question that received considerable interest from language teachers and researchers alike is what corrective feedback (CF) should look like to be maximally beneficial to learners’ second language development. This chapter zooms in on two feedback types that have been distinguished in the CF literature: focused and unfocused CF. After a careful characterization of these two feedback options, theoretical, methodological, and pedagogical arguments are discussed for both of them. The chapter furthermore provides a synthesis of oral and written feedback studies into the (relative) value of focused and unfocused CF. It concludes with suggestions for further research and implications for L2 classrooms.

Background: Early childhood caries is considered one of the most prevalent diseases in childhood, affecting almost half of preschool-age children globally. In the Netherlands, approximately one-third of children aged 5 years already have dental caries, and dental care providers experience problems reaching out to these children. Objective: Within the proposed trial, we aim to test the hypothesis that, compared to children who receive usual care, children who receive the Toddler Oral Health Intervention as add-on care will have a reduced cumulative caries incidence and caries incidence density at the age of 48 months. Methods: This pragmatic, 2-arm, individually randomized controlled trial is being conducted in the Netherlands and has been approved by the Medical Ethics Research Board of University Medical Center Utrecht. Parents with children aged 6 to 12 months attending 1 of the 9 selected well-baby clinics are invited to participate. Only healthy children (ie, not requiring any form of specialized health care) with parents that have sufficient command of the Dutch language and have no plans to move outside the well-baby clinic region are eligible. Both groups receive conventional oral health education in well-baby clinics during regular well-baby clinic visits between the ages of 6 to 48 months. After concealed random allocation of interventions, the intervention group also receives the Toddler Oral Health Intervention from an oral health coach. The Toddler Oral Health Intervention combines behavioral interventions of proven effectiveness in caries prevention. Data are collected at baseline, at 24 months, and at 48 months. The primary study endpoint is cumulative caries incidence for children aged 48 months, and will be analyzed according to the intention-to-treat principle. For children aged 48 months, the balance between costs and effects of the Toddler Oral Health Intervention will be evaluated, and for children aged 24 months, the effects of the Toddler Oral Health Intervention on behavioral determinants, alongside cumulative caries incidence, will be compared. Results: The first parent-child dyads were enrolled in June 2017, and recruitment was finished in June 2019. We enrolled 402 parent-child dyads. Conclusions: All follow-up interventions and data collection will be completed by the end of 2022, and the trial results are expected soon thereafter. Results will be shared at international conferences and via peer-reviewed publication.

From the article: "Whilst the importance of online peer feedback and writing argumentative essays for students in higher education is unquestionable, there is a need for further research into whether and the extent to which female and male students differ with regard to their argumentative feedback, essay writing, and content learning in online settings. The current study used a pre-test, post-test design to explore the extent to which female and male students differ regarding their argumentative feedback quality, essay writing and content learning in an online environment. Participants were 201 BSc biotechnology students who wrote an argumentative essay, engaged in argumentative peer feedback with learning partners in the form of triads and finally revised their original argumentative essay. The findings revealed differences between females and males in terms of the quality of their argumentative feedback. Female students provided higher-quality argumentative feedback than male students. Although all students improved their argumentative essay quality and also knowledge content from pre-test to post-test, these improvements were not significantly different between females and males. Explanations for these findings and recommendations are provided"

Eating rate is a basic determinant of appetite regulation, as people who eat more slowly feel sated earlier and eat less. Without assistance, eating rate is difficult to modify due to its automatic nature. In the current study, participants used an augmented fork that aimed to decelerate their rate of eating. A total of 114 participants were randomly assigned to the Feedback Condition (FC), in which they received vibrotactile feedback from their fork when eating too fast (i.e., taking more than one bite per 10 s), or a Non-Feedback Condition (NFC). Participants in the FC took fewer bites per minute than did those in the NFC. Participants in the FC also had a higher success ratio, indicating that they had significantly more bites outside the designated time interval of 10 s than did participants in the NFC. A slower eating rate, however, did not lead to a significant reduction in the amount of food consumed or level of satiation.These findings indicate that real-time vibrotactile feedback delivered through an augmented fork is capable of reducing eating rate, but there is no evidence from this study that this reduction in eating rate is translated into an increase in satiation or reduction in food consumption. Overall, this study shows that real-time vibrotactile feedback may be a viable tool in interventions that aim to reduce eating rate. The long-term effectiveness of this form of feedback on satiation and food consumption, however, awaits further investigation.

From PLoS website: In general, dietary antigens are tolerated by the gut associated immune system. Impairment of this so-called oral tolerance is a serious health risk. We have previously shown that activation of the ligand-dependent transcription factor aryl hydrocarbon receptor (AhR) by the environmental pollutant 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) affects both oral tolerance and food allergy. In this study, we determine whether a common plant-derived, dietary AhR-ligand modulates oral tolerance as well. We therefore fed mice with indole-3-carbinole (I3C), an AhR ligand that is abundant in cruciferous plants. We show that several I3C metabolites were detectable in the serum after feeding, including the high-affinity ligand 3,3´-diindolylmethane (DIM). I3C feeding robustly induced the AhR-target gene CYP4501A1 in the intestine; I3C feeding also induced the aldh1 gene, whose product catalyzes the formation of retinoic acid (RA), an inducer of regulatory T cells. We then measured parameters indicating oral tolerance and severity of peanut-induced food allergy. In contrast to the tolerance-breaking effect of TCDD, feeding mice with chow containing 2 g/kg I3C lowered the serum anti-ovalbumin IgG1 response in an experimental oral tolerance protocol. Moreover, I3C feeding attenuated symptoms of peanut allergy. In conclusion, the dietary compound I3C can positively influence a vital immune function of the gut.

Schrijven is een effectief middel om te leren, en vindt plaats in alle vakken. Hoe kunnen taal- en vakdocenten door interactie en feedback bijdragen aan het schrijfproces en -resultaat van hun leerlingen? Hoe kunnen leerlingen en studenten leren om adequate school- en vaktaal te gebruiken en hun tekst goed te structureren? Taalgericht vakonderwijs biedt mogelijkheden om leerlingen zich deze vaardigheden eigen te laten maken. Expliciete instructie en op de leerling afgestemde feedback zijn hierbij essentieel, oftewel: de interactie tussen docent en leerling speelt een belangrijke rol.

In programmatic assessment (PA), an arrangement of different assessment methods is deliberately designed across the entire curriculum, combined and planned to support both robust decision-making and student learning. In health sciences education, evidence about the merits and pitfalls of PA is emerging. Although there is consensus about the theoretical principles of PA, programs make diverse design choices based on these principles to implement PA in practice, fitting their own contexts. We therefore need a better understanding of how the PA principles are implemented across contexts—within and beyond health sciences education. In this study, interviews were conducted with teachers/curriculum designers representing nine different programs in diverse professional domains. Research questions focused on: (1) design choices made, (2) whether these design choices adhere to PA principles, (3) student and teacher experiences in practice, and (4) context-specific differences between the programs. A wide range of design choices were reported, largely adhering to PA principles but differing across cases due to contextual alignment. Design choices reported by almost all programs include a backbone of learning outcomes, data-points connected to this backbone in a longitudinal design allowing uptake of feedback, intermediate reflective meetings, and decision-making based on a multitude of data-points made by a committee and involving multi-stage procedures. Contextual design choices were made aligning the design to the professional domain and practical feasibility. Further research is needed in particular with regard to intermediate-stakes decisions.

Objective This scoping review aims to identify complex health interventions (CHI’s) to prevent early childhood caries (ECC), explore the level of complexity of the identified CHI’s, and explore the details of their development, evaluation, and implementation. Introduction Many interventions to prevent ECC have multiple interacting components and can be seen as CHI’s. Recent reviews on these interventions have found inconclusive effects, which may be due to differences in the development, evaluation, and implementation of CHI’s. Inclusion criteria This scoping review will consider clinical trials reporting CHI’s to prevent ECC that starts during pregnancy or in the first year of life. Studies in the English language will be included regardless of the country of origin, sociocultural setting, or context. Methods This review will follow the Joanna Briggs Institute methodology for scoping reviews. An initial search of PubMed identified keywords and Medical Subject Headings terms. A second search of PubMed, Embase, Clarivate Analytics/Web of Science Core Collection, ClinicalTrials.gov, and the Wiley/Cochrane Library will follow. Two independent reviewers will perform title and abstract screening, retrieve and review full-text studies, and extract data. The reference lists of all included sources will be screened for additional CHI’s or relevant publications about a specific CHI. Data charting will be utilised based on study characteristics and intervention complexity. A 39-item instrument will be used to explore the details in the description of the CHI’s development, evaluation, and implementation. The results will be presented in tables, visual outputs, and a narrative summary in response to the review questions. Discussion The proposed review will generate evidence which may provide a direction for the future design of studies on CHI’s to prevent ECC and more complete information for those who want to adopt successful interventions to prevent ECC.
