We report the findings of a large-scale (n = 1,337) qualitative descriptive analysis of U.S. high schools students' particulate representations of a chemical reaction, specifically, the combustion of methane. Data were collected as part of an end of course exam. Student representations were coded into 17 distinct subcategories under one of five…

The cause of the seasons is often associated with a very particular alternative conception: That the earth's orbit around the sun is highly elongated, and the differences in distance result in variations in temperature. It has been suggested that the standard diagrams used to depict the earth's orbit may be in some way responsible for the initial…

Slides similar to "Coming Attractions" shown in cinemas were displayed prior to classes at a mid-western university over three semesters. More than 140 PowerPoint slides, featuring humor, psychology content, and department/faculty information were presented immediately prior to undergraduate psychology class lectures. The primary goals were to…

Venn diagrams are illustrations used in the branch of mathematics known as set theory. Invented in the 19th century by John Venn (1880), they show all of the possible mathematical or logical relationships between sets (groups of things). They are particularly attractive as pictorial representations of leadership issues in schools because they…

This study investigated elementary school teachers' comprehension of data displays. Assessment, interview, and observation data were analyzed to determine their level of comprehension. Results revealed that the teachers were proficient at "reading the data" and computation types of "reading between the data" questions, but were…

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…
