For this assignment, experienced science teachers reviewed exemplary online lessons for teaching human blood circulation at the middle school level. MERLOT resources with practical labs about cardiovascular physiology were examined. Faculty compared and contrasted resources with labs appropriate for instructing secondary school science. Three sources were examined: Harvard Project Zeros Active Learning Practices for Schools, University of California at Berkeleys Web-based Inquiry Science Environment, and the Archive of Teaching Resources of the American Physiological Society. Findings show diverse perspectives on what constitutes quality for practical cardiovascular labs.

This assignment asks science teachers to demonstrate knowledge, experience, and confidence regarding a process called assessment-driven design, also termed backwards design by Wiggins and McTighe (1998). The central goal is to communicate with others for curricular design - to identify learning objectives and use the objectives to guide all phases of curriculum and activity design, continuously evaluating whether the activities are aligned with the target objectives. Materials on MERLOT are assessed according to the driving question and other criteria of sound pedagogy drawn from the analytical procedure from Project 2061 (Kesidou & Roseman, 2002), such as taking account of students prior conceptions, providing first hand inquiry experience with phenomena, and providing a sense of purpose connected to the target science in each activity.
The assignment requires developing an electronic portfolio created using the KML Snapshot Tool, a part of the KEEP Toolkit, developed at the Knowledge Media Lab of The Carnegie Foundation for the Advancement of Teaching.
Text of Learning Exercise:
Select and review an online description of a lesson for teaching human blood circulation at the middle school level. As you examine the lesson, prepare to discuss what characteristics you think are essential for a high quality practical cardiovascular lab.
Describe the collection that houses the blood circulation learning material. What is the purpose for the online collection? Is it easy to find the material of interest?
What Core Concepts or skills should students know as a result of using the learning material?
What Driving Questions engage students and helps establish their prior knowledge of the material?
What Claims are made about student learning from the material and does the Evidence provided support those claims?
Describe Examples of Student Work. What tasks did the student try to accomplish, what was valued, what skills does the student demonstrate, or what content was the student on the verge of understanding?
Prepare to describe what you learned from the work in terms of Strengths and Concerns. How well did the material work in terms of the driving question and other criteria of sound pedagogy drawn from the analytical procedure from Project 2061 (Kesidou & Roseman, 2002)? Does the material take account of students prior conceptions,
provide first hand inquiry experience with phenomena, and provide a sense of purpose connected to the target science in each activity?
