Comprehension monitoring in students with reading difficulties

Two studies are reported in this paper. In the first study, 32 fifth and sixth grade poor readers and 32 average third graders matched with the poor readers on reading age were randomly assigned to either a general or a specific instruction condition. In both treatments subjects were shown how to monitor text for internal inconsistency. In addition, the specific instruction condition provided explicit instruction in how to use a cross-referencing technique to evaluate the internal consistency of a given text. Results indicated significant Subject-group x Instruction Condition interaction on all three dependent measures: detection and identification of inconsistency and comprehension competence. Whereas the poor readers were found to be inferior to the RA-matched controls in the general instruction condition, in the specific instruction condition the poor readers’ performance was superior to that of the RA-matched controls. It was suggested that the significant discrepancy in performance between the poor readers and the younger RA-matched controls in the specific instruction condition may be related to differences in maturity and experience. The validity of this interpretation was examined in the second study by including a third group of average fifth graders matched with the poor readers on chronological age. Further, a second evaluative standard, namely, violation of prior knowledge, was also included. Data from the second study in general confirmed the findings of the first study.

Impact of Structured Movement Time on Preschoolers’ Physical Activity Engagement

Preschool-aged children are not meeting national physical activity recommendations. This study compares preschoolers’ physical activity engagement during two different physical activity opportunities: outdoor free play or a structured movement session. Eighty-seven children served as participants: 40 children participated in outdoor free play and another 47 children participated in a planned movement session. Children in the movement program replaced their outdoor free play with a structured movement session on 2 days each week. All movement opportunities were 30-min in duration. Physical activity was objectively measured using accelerometers. Results show that, compared to children on the playground, children in the movement program engaged in less sedentary behaviors and more light, moderate, vigorous and moderate to vigorous physical activity. In total, children in the movement program engaged in 15.5 min of healthier physical activity behaviors as compared with children in the outdoor free play. Structured movement time appears to afford children an opportunity to engage in more physical activity than outdoor time alone. Findings support that preschool centers should provide children with a daily structured movement time that includes formalized instruction in addition to regularly scheduled outdoor free play.     

A blended learning curriculum for training peer researchers to conduct community-based participatory research

Peer researchers (PRs) are research team members who share traits (e.g. gender, age, sexual orientation, diagnosis, income, housing situation, etc.) with study participants. Participatory methods and some fields (e.g. HIV/AIDS) expect PRs to be equitably involved in a project. Moreover, in Canada, there is a current impetus to include ‘the patient’ in health research. PRs often join a project without any formal research training, yet they are frequently tasked with suggesting appropriate language, recruiting participants, conducting interviews, administering surveys, analyzing data, and presenting findings. While there is literature on PR hiring, ethical considerations of PR engagement, and PR experiences, the methods of training PRs remain underreported. A blended learning curriculum (i.e. combination of webinars, didactic in-person presentation, filmed simulation, etc.), informed by the principles of action learning and the concept of reciprocity, has shown preliminary effectiveness in training PRs across two studies. This paper will present the curriculum, alongside exploratory evaluation results (n?=?7), with details on how the curriculum changed from one study to the next and how reciprocity between academic and peer researchers led to stronger collaborations.     

Spying on children during a school playground intervention using a novel method for direct observation of activities during outdoor play

Our aims were to examine the efficacy of a new observational instrument ‘System for Observing Outdoor Play’ for detecting changes in outdoor play and chart the use of recycled and repurposed materials in the school playground during the course of an intervention to increase outdoor play. Children from one Sydney primary school were observed (N = 111; 5–12 years) using an observational instrument developed as part of the Sydney Playground Project. Data on types of activities and frequencies were collected at baseline and seven times during intervention. Use of intervention materials was consistently high and associated with increases in play-related activities (40–77%), while inactive pursuits decreased (52–31%), on average. The observational instrument proved efficacious in tracking changes in play. Modification of the school playground environment by introducing loose parts changed children’s play-related behaviour; the variety of activities increased, including construction and creative play. Physical inactivity decreased. Recycled materials can increase children’s creative, social and physical play.     

Towards precision medicine: from quantitative imaging to radiomics

Radiology (imaging) and imaging-guided interventions, which provide multi-parametric morphologic and functional information, are playing an increasingly significant role in precision medicine. Radiologists are trained to understand the imaging phenotypes, transcribe those observations (phenotypes) to correlate with underlying diseases and to characterize the images. However, in order to understand and characterize the molecular phenotype (to obtain genomic information) of solid heterogeneous tumours, the advanced sequencing of those tissues using biopsy is required. Thus, radiologists image the tissues from various views and angles in order to have the complete image phenotypes, thereby acquiring a huge amount of data. Deriving meaningful details from all these radiological data becomes challenging and raises the big data issues. Therefore, interest in the application of radiomics has been growing in recent years as it has the potential to provide significant interpretive and predictive information for decision support. Radiomics is a combination of conventional computer-aided diagnosis, deep learning methods, and human skills, and thus can be used for quantitative characterization of tumour phenotypes. This paper discusses the overview of radiomics workflow, the results of various radiomics-based studies conducted using various radiological images such as computed tomography (CT), magnetic resonance imaging (MRI), and positron-emission tomography (PET), the challenges we are facing, and the potential contribution of radiomics towards precision medicine.     

The mediastinal waltz - a representation of asymmetrical mediastinal anatomy

This article describes a representation formed by a waltzing couple of two students that can be used to teach the asymmetrical anatomical relationships among the trachea, bronchi, pulmonary trunk, and the pulmonary arteries in the mediastinum.
