While research has investigated risk-taking in play for children from the age of four years upwards, less is known of risky play with children under four years. A small-scale observational study with children from five childcare settings with differing characteristics was undertaken to explore the occurrence and characteristics of risky play for…

The number of articles showing dissatisfaction with the null hypothesis statistical testing (NHST) framework has been progressively increasing over the years. Alternatives to NHST have been proposed and the Bayesian approach seems to have achieved the highest amount of visibility. In this last part of the special issue, a few alternative…

In two studies, Providence Children's Museum investigated caregivers' observations and perceptions of their children's play and learning at the museum. In the first, caregivers (N = 40) were interviewed about what they observed children doing, what they believed children were thinking about, and their own thoughts and actions while watching…

Feedback is powerful. Everybody needs feedback. The need for feedback includes teachers. It's time to transform delivery of instruction and teacher-education with a powerful, 2-step observation-feedback process. Clarity of expectations set the stage for observation. Feedback is delivered instantaneously and regularly. Actionable feedback gets…

Little is known about how observers' scanning strategies affect performance when monitoring events in closed-circuit television (CCTV) footage. We examined the fixation behaviour of change detectors and non-detectors monitoring dynamic scenes. One hundred forty-seven participants observed mock CCTV videos featuring either a mock crime or no crime.…

Lifeguard surveillance is a complex task that is crucial for swimmer safety, though few studies of applied visual search have investigated this domain. This current study compared lifeguard and non-lifeguard search skills using dynamic, naturalistic stimuli (video clips of confederate swimmers) that varied in set size and type of drowning.…

The play needs of under threes is an under-researched area. In this study, 100 parents and carers were surveyed regarding their visit to a children's museum with a child under three. Using a play taxonomy and observation schedule devised for the study, 50 toddlers were also observed playing with the museum exhibits. The findings showed that whilst…

Recent literature places more emphasis on assessment comments rather than relying solely on scores. Both are variable, however, emanating from assessment judgements. One established source of variability is "contrast effects": scores are shifted away from the depicted level of competence in a preceding encounter. The shift could arise…

Our motivation for this article is for students to realize that opportunities for discovery are all around them. Discoveries that can still puzzle present day researchers. Here we explore an observation by a middle school student concerning the production of what appears to be water-like "ripples" produced in aluminum foil when placed…

This paper presents research carried out in a kindergarten in Catalonia with the aim of studying the different kinds of musical activity that take place during one school day. This is an ethnographic study where the researcher became an extra teacher in a group of one to two-year-olds and interacted with them musically. The methodology is based in…

Range restrictions, or raters' tendency to limit their ratings to a subset of available rating scale categories, are well documented in large-scale teacher evaluation systems based on principal observations. When these restrictions occur, the ratings observed during operational teacher evaluations are limited to a subset of the available…

The Mathematics Scan (M-Scan), a content-specific observational measure, was utilized to examine the extent to which "standards-based mathematics teaching practices" were present in three focal lessons. While previous studies have provided evidence of validity of the inferences drawn from M-Scan data, no prior work has investigated the…

The Autism Diagnostic Observation Schedule (ADOS) is a widely utilized observational assessment tool for diagnosis of autism spectrum disorders. The original ADOS was succeeded by the ADOS-G with noted improvements. More recently, the ADOS-2 was introduced to further increase its diagnostic accuracy. Studies examining the validity of the ADOS have…

Educator professional development (PD) is critical for improving instruction and student achievement. However, there are few frameworks for developing and designing PD based on educators' needs. We report the findings from a case study highlighting how an elementary school and university collaborated to address teachers' needs in the area of…

Adherence to prescribed training intensity (i.e., swim speed) has been conveyed as a key parameter regarding improvements in seasonal performance. Evidence has also suggested swimmers have difficulty complying with coach-prescribed training. How this compliance is affected by a coaching presence and oversight has yet to be examined. Purpose: The…
