摘要

This paper describes the implementation and results from the study of a novel teaching and learning experience in informal K-12 Engineering Education. The experience was embedded in a technology centered discovery-based afterschool program designed and delivered to 116 seventh grade students. Participants were expected to take part in the afterschool program for two-years, beginning in their seventh grade, thereby providing for an in-depth year-round experience. This effort is part of a three-year National Science Foundation (NSF) sponsored project under the Information Technology Experiences for Students and Teachers (ITEST) program. Middle school students took part in a long-term in-depth afterschool program over two-years that included both school year and summer experiences where they engaged in a variety of technology-rich project-based challenges. Site selection met the NSF ITEST program objectives of targeting underrepresented populations in the STEM fields. A purposeful selection strategy was used to select cohorts from four middle schools in the greater Phoenix area in Arizona. The project was launched in 2007 with cohort 1 (n=48) drawn from two schools. In 2008, cohort 2 (n=68) drawn from two other schools was added. Research efforts reported here focus on studying the impact of a Desert Tortoise thematic unit. This thematic unit was the first experience in the students' two-year long engagement with this project. Students were charged with creating a desert tortoise simulation and a realistic desert tortoise habitat. Desert tortoise simulations were created using Lego Mindstorms NXT, while the habitats were constructed from existing landscapes, household materials, and common art supplies. In this paper we describe strategies used to access seventh grade students' understanding of the natural sciences related ideas of desert tortoise behaviors and the direct relationship of these ideas with their notions of what was necessary to build a robot to mimic those behaviors.
