Using information from precision farmer surveys conducted in the southern United States in 2005 and 2013, we evaluated changes in the use of precision farming information sources among cotton producers. Although Extension remains an important source for producers interested in precision farming information, the percentage of cotton producers using…

Recent studies on visual working memory (VWM) have shown that visual information can be stored in VWM as continuous (e.g., a specific shade of red) as well as categorical representations (e.g., the general category red). It has been widely assumed, yet never directly tested, that continuous representations require more VWM mental effort than…

This paper evaluates literature surrounding the effectiveness of Precision Teaching (PT) for improving the skill acquisition of children with autism. PT's aim is the attainment of behavioural fluency across educational and social contexts, as well as potentiality to enhance the learning of pupils with autism. This review evaluates the existing…

The aim of this study is to examine the relationships between pre-service teachers' critical thinking skills and their self-efficacy for argumentation. The participants of the research consisted of 858 pre-service teachers (447 female, 411 male) studying in education faculties at five different state universities in Turkey. In this study, the…

Purpose: The dual goals of this tutorial are (a) to increase awareness and use of mediation and moderation models in cognitive-communication rehabilitation research by describing options, benefits, and attainable analytic approaches for researchers with limited resources and sample sizes and (b) to describe how these findings may be interpreted…

A recent state-wide curricular shift in developmental course offerings mandated that the exit levels of developmental reading and writing coursework in every public institution of higher education in Texas be merged into one accelerated and integrated developmental reading and writing course. This project examined the effects of that curricular…

Two recent publications in "Educational and Psychological Measurement" advocated that researchers consider using the a priori procedure. According to this procedure, the researcher specifies, prior to data collection, how close she wishes her sample mean(s) to be to the corresponding population mean(s), and the desired probability of…

We investigated whether clustering based on feature similarity improves the representational quality of visual working memory (VWM). We hypothesized that similar items are organized into clusters, and their recall precision increases with fewer clusters because of reduced memory load. In a series of 6 experiments, participants remembered…

The current study sought out to advance the Social Self-Efficacy and Social Outcome Expectations scale using multiple approaches to scale development. Data from 583 undergraduate students were used in two scale development approaches: Classic Test Theory (CTT) and Item Response Theory (IRT). Confirmatory factor analysis suggested a 2-factor…

The aim of this study was to investigate the effect of a precision teaching (PT) framework on the mathematical ability of students with intellectual and developmental disabilities. We also examined if students of moderate mathematical ability could perform as well as their peers with fewer difficulties with their math skills. Sixteen students…

Purpose: This study compares the precision of the electromagnetic articulographs used in speech research: Northern Digital Instruments' Wave and Carstens' AG200, AG500, and AG501 systems. Method: The fluctuation of distances between 3 pairs of sensors attached to a manually rotated device that can position them inside the measurement volumes was…

In language assessment and in educational measurement more broadly, there is a tendency to interpret scores from single-administration tests as accurate indicators of a latent trait (e.g., reading ability). Even in contexts where learners receive multiple formative assessments throughout the year, estimates of student ability are determined based…

By exposing students to the concept of digital agriculture earlier in their lives, they will be able to develop the proper mindset to advance the field further when they enter the professional world. Engaging students in activities such as the one described here, which center on the Grand Engineering Challenges and socially relevant contexts, may…

This study compared the precision of ability estimation on different types of item response theory models for mixed-format data. Participants in this study were 1625 Junior High School Students in Depok, Indonesia. The mixed-format test was used to measure the students' ability in mathematics. The test used consists of multiple-choice and…

This work proposes simple experiments to introduce some fundamental concepts of the measurement area. It associates theory and practice through a strategy where the students create a real temperature data set with an Arduino board and three LM35DZ sensors and later use mathematical software to identify theoretical concepts as measurement accuracy…
