Capitalizing on Emerging Technologies: A Case Study of Classroom Blogging

Robyn MacBride & April Lynn Luehmann

The challenge many teachers face is how to incorporate new technology into their classrooms that strengthens classroom learning by capitalizing on students' media literacies. Blogs, a new and innovative technological tool, can be used in math and science classrooms to support student learning by capitalizing on students’ interests and familiarity with on-line communication. This study explores the emerging blogging practices of one high school mathematics teacher and his class to explore issues of intent, use, and perceived value. Data sources for this case included one year's worth of blog content, an interview with the facilitating teacher, and students' perceptions of classroom blogging practices. Findings indicate that (1) teachers’ intentions focused on creating additional forms of participation as well as increasing student exposure time with content; (2) blogs were used in a wide variety of ways that likely afforded particular benefits; and (3) both teacher and students perceived the greater investment to be worthwhile. The findings are used to critically consider claims made in the literature about the potential of blogging to effectively support classroom learning.

How Students ”Unpack” the Structure of a Word Problem: Graphic Representations and Problem Solving

Kellah Edens & Ellen Potter

This research investigated how fourth and fifth grade students spontaneously ‘unpacked’ a word problem when generating a graphic representation to aid in problem solution. Relationships among the type of graphic representation produced, spatial visualization, drawing ability, gender, and problem solving also were examined and described. Instrumentation developed for the study included several math challenge tasks, a spatial visualization task, and a drawing task. For one of the math challenge tasks, students were instructed to draw a picture to assist them with problem solution. These graphic representations generated by students were rated as pictorial or as displaying some level of schematic representation. Schematic representations included germane information from the problem supportive of problem solution. Pictorial representations included expressive and extraneous elements not necessary for problem solution, with no schematic elements. Findings indicated that the majority of students rendered schematic representations, with girls more likely than boys to use schematic representations at a statistically significant level. Students who used schematic visual representations were more successful problem solvers than those pictorially representing problem elements. The more “schematic-like&rdqou; the visual representation, the more successful students were at problem solution. Drawing a pictorial representation in the math challenge task also was negatively correlated to drawing skill.

Engineers in the Classroom: Their Influence on African-American Students' Perceptions of Engineering

Stephen Thompson & Jed Lyons

A Draw an Engineer Test was used to capture the perceptions of engineering held by two similar groups of 6th grade African-American students. Forty-four students who had graduate level engineers in their classrooms during a prior school year as part of a GK-12 project were matched to 44 students who had not. Matching criteria included race, gender, and academic standing. Using perceptions of common engineering artifacts, fields, tasks and processes as measures, student perceptions were quantified using a Draw an Engineer Test Scoring Guide. Additional descriptive analysis was also conducted. Control group students' perceptions centered on engineering as physical work and portrayed engineers primarily in construction or building trades. Experimental group students were more likely to perceive engineering as involving mental tasks such as designing, presenting and experimenting. Experimental group students also displayed greater awareness and understanding of various engineering fields.
