Supporting collaborative dissection through the development of an online wiki positively impacts the learning of veterinary anatomy

An innovative series of dissections of the canine abdomen was created to facilitate social distancing in the dissection room following COVID-19 restrictions imposed in the UK. In groups of six, first-year veterinary students took turns dissecting selected parts of the canine abdomen while maintaining social distancing and documenting their work with video and photographs. Here, students learned about the canine abdominal anatomy by dissecting, recording the dissections of others in their group, and compiling the recorded material into a collaborative electronic media portfolio (Wiki). An online formative multiple-choice test was created to test students' knowledge of the canine abdominal anatomy. The result analysis showed that although students achieved the learning outcomes only by studying the Wiki, they had better performance in the anatomical areas where they learned through the dissection (p < 0.05). Student performance was very similar in the areas in which they were present in the dissection room and participated in recording the dissection compared with the areas that they effectively dissected (p > 0.05). A qualitative thematic analysis was developed to understand students' opinions via their feedback on this dissection approach. Our results showed that student collaboration and the development of practical skills were the most valued aspects of this dissection teaching initiative. Moreover, these results show that developing a group Wiki has a positive impact on student achievement of learning objectives, with a practical hands-on dissection being fundamental for the optimal learning of the canine abdominal anatomy.     

Books for Babies means books for parents too: the benefits of situating the earliest stages of literacy in the framework of the wider community

This paper describes some findings from the Books for Babies project, a central strand of Derbyshire’s county‐wide literacy initiative, Read On – Write Away! (ROWA!). The original project, initiated by the Derbyshire Libraries and Heritage Service in 1995 was extended through ROWA! by being incorporated into wider ranging community literacy provision. This paper describes preliminary evidence that indicates that there are additional benefits for other family group members when a Book Start project includes follow‐up activities and is connected to wider ranging community literacy initiatives.     

Parent–Child Math Talk About Fractions During Formal Learning and Guided Play Activities

This study examined parent–child math talk within three contexts (formal learning; guided play; unguided play) in order to identify characteristics of activities supporting high-quality math engagement. Seventy-two dyads of parents and 4- and 5-year-olds were observed using a set of toy foods; instructions and materials varied across conditions. Parents and children engaged in the most math talk in formal learning; guided play also yielded more math talk than unguided play. Parents rated the formal learning and guided play activities as equally supportive of math learning, but rated the guided play activity as more enjoyable than the formal learning activity. The findings have implications for how parents should be encouraged to support preschoolers’ math learning.     

School psychologists and suicide risk assessment: Role perception and competency

As the second leading cause of death for adolescents, suicide is a major concern for school personnel. School psychologists' training in mental health makes them well-positioned to lead in suicide prevention efforts; however, studies have shown a lack of preparedness in crisis intervention and, more specifically, suicide risk assessment. This study surveyed practicing school psychologists (N = 92) to explore their perception of both their role and competency in suicide risk assessment. Suicide risk assessment was defined as a broad term pertaining to any measures taken in suicide prevention, intervention, or postvention. The majority of school psychologists reported having a primary role at the tertiary level (i.e., intervening with a student identified as needing help). Participants indicated lacking adequate graduate preparation; however, most participants were confident in their knowledge of suicide and suicide risk assessment and were comfortable identifying and intervening with a student who is suicidal. Implications for practice and directions for future research are discussed.     

Partnering with school providers to codesign mental health interventions: An open trial of Act & Adapt in urban public middle schools

Schools are well positioned to provide access to youth mental health services, but implementing effective programs that promote emotional and behavioral functioning in school settings is complicated by the poor fit of interventions developed in research settings to complex school contexts. The current study formed a research–practice partnership with two urban public schools and mental health providers employed by those schools (N = 6, 100% female, 50% Black/African American, 50% White/Caucasian) in the adaptation of a depression prevention intervention, Act & Adapt. The intervention was modified by decreasing meeting time and streamlining session content, increasing flexibility, making intervention materials more similar to academic curriculum, and increasing the focus on managing disruptive behavior within group sessions. In an open trial, sixth-grade students (N = 22; 59% boys, 31% Hispanic, 22% Black/African American, 4% Asian, 30% White/Caucasian) at both schools who were identified as clinically “at risk” reported improvements from baseline to postintervention and at 1-year follow-up on measures of emotional and behavioral difficulties and coping strategies, with parallel results by caregiver report. The providers reported satisfaction with the intervention, and qualitative analyses of provider focus groups suggested both barriers and facilitators to research-practice collaborations to implement mental health interventions in schools.     

Acute and chronic effects of foam rolling vs eccentric exercise on ROM and force output of the plantar flexors

Foam rolling and eccentric exercise interventions have been demonstrated to improve range of motion (ROM). However, these two modalities have not been directly compared. Twenty-three academy soccer players (age: 18 ± 1; height: 1.74 ± 0.08 m; body mass: 69.3 ± 7.5 kg) were randomly allocated to either a foam rolling (FR) or eccentric exercise intervention designed to improve dorsiflexion ROM. Participants performed the intervention daily for a duration of four weeks. Measurements of dorsiflexion ROM, isometric plantar flexion torque and drop jump reactive strength index were taken at baseline (pre-intervention) and at three subsequent time-points (30-min post, 24-hours post and 4-weeks post). A significant time x group interaction effect was observed for dorsiflexion (P = 0.036), but not for torque or reactive strength index. For dorsiflexion, there was a significant increase in both acute (30-min; P < 0.001) and chronic (4-week; P < 0.001) ROM for the eccentric group, whilst FR exhibited only an acute improvement (P < 0.001). Eccentric training would appear a more efficacious modality than foam rolling for improving dorsiflexion ROM in elite academy soccer players.     

Running quietly reduces ground reaction force and vertical loading rate and alters foot strike technique

This study aimed to determine if a quantifiable relationship exists between the peak sound amplitude and peak vertical ground reaction force (vGRF) and vertical loading rate during running. It also investigated whether differences in peak sound amplitude, contact time, lower limb kinematics, kinetics and foot strike technique existed when participants were verbally instructed to run quietly compared to their normal running. A total of 26 males completed running trials for two sound conditions: normal running and quiet running. Simple linear regressions revealed no significant relationships between impact sound and peak vGRF in the normal and quiet conditions and vertical loading rate in the normal condition. t-Tests revealed significant within-subject decreases in peak sound, peak vGRF and vertical loading rate during the quiet compared to the normal running condition. During the normal running condition, 15.4% of participants utilised a non-rearfoot strike technique compared to 76.9% in the quiet condition, which was corroborated by an increased ankle plantarflexion angle at initial contact. This study demonstrated that quieter impact sound is not directly associated with a lower peak vGRF or vertical loading rate. However, given the instructions to run quietly, participants effectively reduced peak impact sound, peak vGRF and vertical loading rate.     

Overcoming response bias using symbolic representations of number by chimpanzees (Pan troglodytes)

We previously reported that chimpanzees were unable to optimally select the smaller of two candy arrays in order to receive a larger reward. When Arabic numerals were substituted for the candy arrays, animals who had had prior training with numerical symbols showed an immediate and significant improvement in performance and were able to select reliably the smaller numeric representation in order to obtain a larger reward. Poor performance with candy arrays was interpreted as reflecting a response bias toward the intrinsic incentive and/or perceptual features of the larger array. In contrast, the Arabic numerals represent numerosity symbolically and appear to promote response choice on the basis of abstract processing of numerosity, with minimal interference from the inherent properties of the choice stimuli. The present study tested the hypothesis that, for mixed symbol-candy choice pairs, the requisite processing of the abstract numeral may foster a mode of numerical judgment that diminishes the interfering incentive/perceptual effects of the candy stimuli. The results were consistent with this hypothesis. Whereas performance on candy-candy arrays was significantly below chance levels, performance on numeral-candy choice pairs was significantly above chance and comparable with performance on numeral-numeral pairs.
