The purpose of this study was to adapt the Statistics Anxiety Rating Scale (STARS) for a Greek student population. The STARS was administered to 890 Tertiary Education students in two Greek universities. It was performed a cross-validation study to examine the factorial structure and the psychometric properties with a series of confirmatory factor…

U.S. elementary schools administer reading screeners to identify students in need of remedial instruction. However, the administration of additional assessments comes with a cost. It is unclear the extent to which multiple types of reading screeners warrant the increase in resources that could be used for instruction. This study compared…

In this study, it is aimed to reveal the models related to star subject as one of the concepts of astronomy of prospective science teachers before and after the current instruction through model analysis. This modeling situation is expressed as a Grounded Mental Model (GMM), since there will be a mental modeling that is revealed according to what…

The typical sound of George Lucas' laser blaster in the "Star Wars" series is well known. What does a laser blaster in "Star Wars" sound like, and why? Here we show a simple way to produce this sound by using low-cost lab material, like a spring or a Slinky. Building on the work of Crawford, who analyzed the sound of a Slinky…

Stellar aberration is the phenomenon whereby the observed angular position of a star depends on the relative motion between the star and Earth. Specifically, a telescope must be tilted slightly into the direction of motion of Earth relative to the star. There are in fact three different angular positions of interest: the observed position of the…

Stars form from large clouds of gas and dust that contract under their own gravity. The birth of a star occurs when a fusion reaction of hydrogen into helium is ignited in its core. The key variable that determines the formation of a star is mass. If the mass of the contracting cloud is below a certain minimum value, instead of a star, a substelar…

Repeated measurements of student ability (i.e., progressing monitoring) is an essential element of informed decision-making when adjusting instruction. An important characteristic of progress monitoring measures is frequent administration to identify areas of concern and to evaluate academic growth. The purpose of this study was to determine if…

A good education is the necessary element at the foundation of efforts to lift people out of poverty, reduce inequalities, tackle prejudices, skill the next generation to face a job market being transformed by technology, and train the scientists and leaders who will answer the enormous challenges society faces from climate change to pandemics and…

Thanks to rapid increases in the state's Hispanic and Asian populations, the number of Texas students classified as English Learners has surged in the past decade, from approximately 830,000 in 2010 to more than 1.1 million today. In the charter sector, change has been even more rapid. In 2010, 16 percent of charter students in Texas were…

In any procedural mathematical situation, there are multiple ways of achieving the same answer. Given this observation, we ask, why choose one procedural solution over another? We address this question here with data drawn from interviews conducted with university students engaged in row-reducing matrices. During their tasks, the students voiced a…

Little is known about the experiences of lesbian and gay faculty and students in continuing education. In order to address this gap, this article introduces and discusses a research project conducted to understand the struggles and accomplishments of both lesbian and gay male faculty and students in continuing education (CE) in university…

This paper provides a survey of the research on the relationship between teachers' professional knowledge and their instructional quality in the domain of mathematics education. First, an overview is provided of the way in which mathematics professional knowledge has been conceptualized. Second, the relation between mathematics teachers'…

Predicates like "coloring-the-star" denote events that have a temporal duration and a culmination point ("telos"). When combined with perfective aspect (e.g., "Valeria has colored the star"), a culmination inference arises implying that the action has stopped, and the star is fully colored. While the perfective aspect…

Young children, students, and adults may have alternative ideas about the motion of the Sun and stars as we observe them in the sky. However, a good understanding of this apparent motion is essential as a starting point to study more advanced astronomical concepts, especially when these include astronomical observations. In this paper, we describe…

Many elementary school students require and may benefit from supplemental reading support and interventions that can be provided by afterschool programs. The problem addressed in this study was that it was not known if third grade students benefited from an afterschool reading program in one East Tennessee District. The purpose of this…
