Revision as of 16:16, 17 July 2006
The project-based science (PBS) model is a project-oriented instructional design model from the Project-Based Science (PBS) project, an effort that began in 1991 at the University of Michigan School of Education.
According to Lin & Fishman (2006), “the five design principles for PBS curriculum units (Singer, Marx, Krajcik, & Chambers, 2000) are: (1) establish meaningful context; (2) engage in scientific inquiry; (3) collaborate to share/refine understandings; (4) utilize learning tools; and (5) create class/individual artifacts.”
See the PIViT software (also a PBS project).
The model
The design principles of project-based science curricula are according to Lin & Fishman (2006)'s interpretation of Singer et. al 2000):
Name | Description | Examples |
---|---|---|
Establish meaningful context | Meaningful, defined problem space that provides intellectual challenge for the learner. | Driving question and sub-questions Anchoring event |
Engage in scientific inquiry | A set of interrelated processes by which scientists and students pose questions about the natural world and investigate phenomena | Asking questions Data collection and analysis Communicating data |
Collaborate to share/refine understandings | Interaction among students, teachers, and community members to share information and negotiate meaning | Small-group design meetings Think-pair-share learning strategy Group presentations |
Utilize learning tools | Tools that support students in intellectually challenging task | Data collection Communication Modeling |
Create class/individual artifacts | Representations of ideas or concepts that can be shared, critiqued, and revised to enhance learning | Concept maps Scientific models Lab reports |
Example
According to Timmerman et al. (2006:11), such instructional design models are appropriate for more abstract topics and/or those where students tend to have well-developed prior ideas (misconceptions): “Thus, when faced with limited time or resources for curriculum reform, we agree with Wandersee et al. (1994) that conventional teaching is sometimes sufficient and our data suggest that more "high-powered" methods such as inquiry-based curriculum reform should focus on more abstract topics or those known to be resistant to conceptual change. Indeed, we would hypothesize that it is nearly impossible to change students' conceptions of abstract topics such as evolution using only didactic methods and that inquiry-based methods which allow students to confront their prior conceptions are required for meaningful learning to occur in these areas.”
Timmerman et al (2006: 12) provided comparison of inquiry and "didactic curricula" regarding "evolution" that we slightly modified.
Elements | Design Principle Reformed inquiry-based curriculum | Traditional, didactic curriculum |
---|---|---|
Content Topics | Evolution Biodiversity |
Plant and Animal Anatomy and Physiology |
Context | Emphasizes scientific inquiry skills and application of knowledge | Emphasizes reiteration or verification of ideas |
Inquiry | Science inquiry skills explicitly a goal Explicit use of primary literature Explicit, formalized peer review (emphasized as an inquiry skill, not just a process) |
Focused on factual content knowledge No primary literature No peer review. |
Collaboration | Mostly collaborative; group work common | Mostly individual |
Assessments | Summative assessments based on open-ended projects and authentic performances (oral presentation, written reports) - Multi-week assignments - Formative feedback provided | Weekly quizzes, factually oriented (multiple choice or fill-in-blanks) with a practical exam at end of term. Single lab activities with the exception of the rat dissection No formative feedback |
Learning Technologies | Beguile-like environments | Interactive dissection video and images |
