Background  Use of 21 st century collaborative workplace tools is on the rise  Technologically rich “dispersed” collaboration requires (Olson & Olson, 2000):  Common ground  Coupling of work  Technological readiness  Collaborative readiness 2

PADI Project  Seeks to improve assessment of inquiry in science learning  Networked collaboration  Development and use of Web-based tool 3

Central Process The central process for project strands working with the PADI Design System can be stated as follows: The interaction between assessment materials (e.g., assessment tasks) and the Evidence-Centered Design framework (Mislevy, Steinberg, & Almond, 2002) is mediated by various tools, representational forms, and representations utilized by collaborative workgroups. 4

5 PADI Assessment Design

 Goals:  To reverse engineer a performance task from a large-scale, national assessment  To use the PADI System as an analytical tool for understanding task features  In reverse engineering and analyzing a performance assessment task via PADI, what types of knowledge were created? 6 NAEP Performance Assessment

1. Selection of a Set of Items (July – August) 2. Exploration of the Floating Pencil Task (August – December) 3. Development of a Task Specification (December – March) 7 Reverse Engineering & Analysis Process

 We selected a set of items for analysis  NSES inquiry standards, PADI Design Patterns  Defined our Student Model  Exploration of multiple student models  Choice of NAEP framework  Refined the Student Model 8 The Student Model

 We explored evaluation & measurement issues via the PADI representational forms  Evaluative Sub-Model based on NAEP rubric  Multiple levels of conditional dependencies  MRCML psychometric model  Clarified our Measurement Model  Based closely on NAEP practices  Elements of PADI 9 The Evidence Model

 We explored attributes of the Floating Pencil task  Content-lean, inquiry-constrained  Use of lab materials; High verbal demand  Constructed Task Model  Sought to define a ‘Family of Tasks’ 10 The Task Model

 Process: Floating Pencil team engaged in collaboration using technological workplace tools  Results:  Analysis of the Floating Pencil task  A ‘trace’ on PADI: Floating Pencil Task Specification  The impact of our work on PADI Design System  Next Steps:  Task family and TMVs  Empirical data analysis  Technical report on Floating Pencil work  Consideration of alternative student models 11 So What?
