Oral reading fluency (ORF) assessments are commonly used to screen at-risk readers and to evaluate the effectiveness of interventions as curriculum-based measurements. As with other assessments, equating ORF scores becomes necessary when we want to compare ORF scores from different test forms. Recently, Kara et al. (2023) proposed a model-based…

Objectives: This study aimed to evaluate the fidelity and accuracy of a smartphone microphone and recording environment on acoustic measurements of voice. Method: A prospective cohort proof-of-concept study. Two sets of prerecorded samples (a) sustained vowels (/a/) and (b) Rainbow Passage sentence were played for recording via the internal iPhone…

Objective: To examine if Arduino microcontrollers and Fitbits can serve as proxy measures for the direct observation of sitting and standing time in college students using height-adjustable standing desks. The preferred type of standing desks and reasons to use the desks were also assessed. Design: Classroom-based intervention, plus…

It is well known that the twinkling of stars in the night sky is due to turbulence within the earth's atmosphere causing localised fluctuations in refractive index. The paper describes a method for demonstrating the effect to learners during the daytime. This is accomplished by detecting audio frequency fluctuations in the level of direct sunlight…

The Cosmic-Ray Extremely Distributed Observatory (CREDO) is the project to search and study ultra high-energy cosmic ray particles from deep space producing simultaneous extensive air showers over the entire exposed surface of the Earth. The concept of the CREDO infrastructure assumes absorbing all kinds of cosmic ray data from any apparatus all…

One question frequently included in surveys asks about respondents' earnings. As this information serves, for example, as a basis for evaluating policy interventions, it must be of high quality. This study aims to advance knowledge about possible measurement errors in earnings data and the potential of data linkage to improve substantive…

Interest in the study of gene-environment interaction has recently grown due to the sudden availability of molecular genetic data--in particular, polygenic scores--in many long-running longitudinal studies. Identifying and estimating statistical interactions comes with several analytic and inferential challenges; these challenges are heightened…

When practitioners use modern measurement models to evaluate rating quality, they commonly examine rater fit statistics that summarize how well each rater's ratings fit the expectations of the measurement model. Essentially, this approach involves examining the unexpected ratings that each misfitting rater assigned (i.e., carrying out analyses of…

This study is the result of a quantitative analysis of the previous paper reporting on four cases in which an LED is turned on by charge transfer occurring during the electrostatic induction process in a conductor connected to the LED. We were able to measure the charge transfer by using charge sensors and analyze experimental results by applying…

In this study, it is aimed to calibrate an LDR-Lux meter with a calibration setup which includes a light bulb whose brightness can be changed by using a dimmer circuit, a data acquisition card, a smartphone and a lux meter application. In order to make the measurements more accurate and to prevent errors in the measurements, a smartphone and a…

Purpose: Peak and maximal oxygen uptake (VO[subscript 2peak] and VO[subscript 2max], respectively) are used in assessing aerobic power. For swimmers with physical impairments, it is unclear whether the physiological variables obtained in 200-m and Nx200-m tests are similar. The objective of this study is to assess the validity of VO[subscript…

Ballet dancers are exposed to the high likelihood of lower extremity injury due to repeated high-impact jumps under stringent ballet rules. The injury incidences occurring in dancers during jump landings are highly associated with excessive vertical ground reaction forces (vGRF) and the sharp loading rate (LR). The aim of this study was to compare…

The world's move to a global economy has an impact on the high rate of student academic failure. Higher education, as the affected party, is considered crucial in reducing student academic failure. This study aims to construct a prediction (predictive model) that can forecast students' time to graduation in developing countries such as Indonesia,…

In this exchange, the authors each address five questions about creativity, and then provide a final synthesizing response. The five questions they address are: (1) What is creativity? Are there different processes, types, or kinds of creativity, and if so, what are they? (2) What are the major obstacles to people thinking and acting creatively?…

Background: Researchers regularly must decide what information is necessary to understand school climate and how to include climate in a study. For example, which factors and/or scales should be used, is using just 1 scale for school climate sufficient, and to what extent does the selection of a single scale influence the research findings? Aims:…
