We conducted a series of experiments to investigate the extent to which prompting the construction of a force diagram affects student solutions to simple mechanics problems. A total of 891 university introductory physics students were given typical force and motion problems under one of the two conditions: when a force diagram was or was not…

After an outdoor excursion hunting for a "special leaf" on a delightful fall day, students returned to the classroom and were instructed to capture the leaf on a blank page in their science notebooks. They were asked to document as many details as possible, based on their observations. The overall focus of the notebooks was for students to capture…

As part of an instrumentation course, a problem-based learning framework was selected for laboratory instruction. Two acquisition chains were designed to help students carry out realistic instrumentation problems. The first tool is a virtual (simulated) modular acquisition chain that allows rapid overall understanding of the main problems in…

In the last few decades, investigations into the linguistic landscape (LL) have sought to analyse written language practices as they are observable in public space. Whilst the LL analysis of language choice in given contexts has opened a host of possibilities for scientific enquiry in the field, the methodologies employed in the collection and…

In the year 2009, 667 individuals lost their lives in a highway construction or maintenance work zone (National Work Zone Safety Information Clearinghouse, 2010). Since the year 2003, 6,438 individuals have been killed in a highway construction or maintenance work zone, which is approximately 805 deaths per calendar year (National Work Zone Safety…

Shared Reading is a powerful teaching technique for teaching beginning reading. Technologies such as Interactive Whiteboards now make Shared Reading much easier to do. Large texts are projected on the whiteboard for Choral reading, and interactive features allow students to learn about letter-sound correspondences, spelling patterns, punctuation,…

One method in which health professionals can influence adolescent substance use is by correcting social norms. According to the social norms theory, individuals often erroneously believe that the majority of people engage in unhealthy behaviors, a misperception that may motivate individuals to increase their own unhealthy behaviors. The social…

The aim of the present study was to examine the technological affordances of a web-based collaborative learning technology, Knowledge Practices Environment (KPE), for supporting different dimensions of knowledge creation processes. KPE was used by engineering students in a practically oriented undergraduate engineering course. The study…

Students of history are expected to be able to interpret visual images as a source of primary evidence for historical inquiry, yet history teachers may not always place sufficient emphasis on pedagogies that consistently and specifically target the skills of visual interpretation. Developing understanding of visual evidence is sometimes left to…

The role of language for learning is core across the entire school curriculum. Thus, children with speech, language and communication needs are at risk of underachieving academically. Research reports and policy drivers advocate the need for a whole school approach (WSA) to enhance children's spoken language and communication skills, yet little is…

This study investigated whether studying dynamic-static visualizations prepared first-year Biology students better for an out-of-classroom experience in an aquarium than learning how to identify species with more traditional instructional materials. During an initial classroom phase, learners either watched underwater videos of 15 freshwater fish…

This study examined the effect of different anatomic representations on student learning in a human anatomy class studying the muscular system. Specifically, we examined the efficacy of using dissected cats (with and without handouts) compared with clay sculpting of human structures. Ten undergraduate laboratory sections were assigned to three…

This article reports research conducted in the northeastern corner of Egypt's Nile Delta during an excavation at the Mendes archeological dig site in July-August, 2007. Donald Redford, Professor at Pennsylvania State University, accepted the author as the only nonarcheologist that year. In addition to duties of measuring, registering, and storing…

School superintendents annually need to gain affirmative votes from their governing bodies to approve their district budgets. This paper proposes a framework through which the superintendent can express the district's educational needs and concomitant resource allocations in conceptual terms rather than in multi-columned ledgers. The framework…

This paper discusses common approaches to presenting the topic of skewness in the classroom, and explains why students need to know how to measure it. Two skewness statistics are examined: the Fisher-Pearson standardized third moment coefficient, and the Pearson 2 coefficient that compares the mean and median. The former is reported in statistical…
