To test the effects of octave and timbre on tuning accuracy, four stimuli--B-flat 4 sounded by flute, oboe, and clarinet and B-flat 2 sounded by tuba--functioned as reference pitches for high school wind players (N = 72). The two stimulus octaves combined with participants' assigned tuning notes created soprano, tenor, and bass tuning groups. All…

The purpose was to examine how caregivers of infants and toddlers with autism spectrum disorder view their daily activities/routines and in what way, if any, assistive technology (AT) acts as a support. A total of 134 families who reported their child's disability as autism spectrum disorder/pervasive developmental disorder completed a survey…

Eighteen middle and high school students with visual impairments participated in a weeklong field-based geology summer camp. This paper reports the curriculum, strategies, and what the students learned about Earth science by climbing in and out of caves, collecting fossils, exploring a bog, and interacting with experts in the field. Students were…

The process of conceptual change can be described as a three phase process. The first phase involves students' possession of initial naive "conceptions/misconceptions," the second phase involves students undergoing a process of "assimilation," and the third phase involves students undergoing a radical process called…

In this paper, I argue that Friedrich Nietzsche's concept of self-overcoming has been largely misinterpreted in the philosophy of education journals. The misinterpretation partially stems from a misconstruction of Nietzsche's perspectivism, and leads to a conception of self-overcoming that is inconsistent with Nietzsche's educational ideals. To…

The theory of evolution by natural selection has revolutionized the biological sciences yet remains confusing and controversial to the public at large. This study explored how a particular segment of the public--visitors to a natural history museum--reason about evolution in the context of an interactive cladogram, or evolutionary tree. The…

Primary teachers play a key role in their students' future mathematical success in the early secondary years. While the word "algebra" may make some primary teachers feel uncomfortable or worried, the basic arithmetic ideas underlying algebra are vitally important for older primary students as they are increasingly required to use "algebraic…

There are many factors that may influence and impact student-athletes' academic achievement and athletic performance from high school throughout college. These factors may range from family structure, socioeconomic status, parental educational level, parental school involvement, and aspirations. However, few studies have examined these factors in…

Students who harbor misconceptions often find chemistry difficult to understand. To improve teaching about the dissolving process, first semester introductory chemistry students were asked to complete a free-response questionnaire on writing balanced equations for dissolving ionic compounds in water. To corroborate errors and misconceptions…

Learning progressions, or representations of how student ideas develop in a domain, hold promise as tools to support teachers' formative assessment practices. The ideas represented in a learning progression might help teachers to identify and make inferences about evidence collected of student thinking, necessary precursors to modifying…

The main aim of this paper is to report on an investigation into primary pre-service and inservice teachers' content knowledge of decimals. The participants were asked to complete four decimal tasks including the ordering of decimals, operating with decimals and converting a fraction to a decimal. The results from both sets of participants are…

Enzyme function is central to student understanding of multiple topics within the biochemistry curriculum. In particular, students must understand how enzymes and substrates interact with one another. This manuscript describes the development of a 15-item Enzyme-Substrate Interactions Concept Inventory (ESICI) that measures student understanding…

Half of servers in higher ed are virtualized. But that number's not high enough for Link Alander, interim vice chancellor and CIO at the Lone Star College System (Texas). He aspires to see 100 percent of the system's infrastructure requirements delivered as IT services from its own virtualized data centers or other cloud-based operators. Back in…

Many students do not recognize that individual organisms within populations vary, and this may make it difficult for them to recognize the essential role variation plays in natural selection. Also, many students have weak scientific reasoning skills, and this makes it difficult for them to recognize misconceptions they might have. This paper…

This paper describes a randomised educational experiment (n = 47) that examined two different teaching methods and compared their effectiveness at correcting one science misconception using a sample of trainee primary school teachers. The treatment was designed to promote engagement with the scientific concept by eliciting emotional responses from…
