Forming the core of the SEPUP Assessment System are the assessment variables (content and process skills to be assessed), assessment questions or tasks used to gather evidence and scoring guides for interpreting students’ responses (correspond to assessment variables). The seven assessment variables are: Designing Investigations (DI) Organizing Data (OD) Analyzing Data (AD) Understanding Concepts (UC) Evidence and Trade-offs (ET) Communication Skills (CS) Group Interaction (GI) Types of assessment: Quick Checks ( ) present opportunities for informal formative assessment and may be used prior to instruction to find out what students know or think. They may also be used to help teachers track students’ knowledge of key information or progress in understanding a concept. Some embedded questions and tasks and all item bank questions are all suitable for summative assessment. Analysis questions are included at the end of each activity.

Scientists ask questions, make observations, and collect and analyze data, in an attempt to make sense of the natural world. Similarly, engineers create, test, and redesign as they respond with solutions to human needs. And just as we use scaffolds in teaching of scientific inquiry to improve student learning and practice, so do we use scaffolds in teaching about engineering for our students. The NGSF emphasizes three major phases of the engineering design process. DESIGN: Creates design, prototype or plan, noting constraints of proposed use TEST: Tests design, prototype or plan, collecting qualitative or quantitative data REDESIGN: Evaluates prototype, design or plan, suggests further changes as needed In addition, the NGSF emphasizes the role of design in solving human problems, and of designers in developing criteria for solutions, evaluating solutions, and determining the tradeoffs involved in a design or solution. The table below shows SEPUP activities that support major elements of engineering design. Some support the initial stages of design, criteria development, and evaluation that precede the full design cycle by suggesting or evaluating scientific or technological solutions to real-world problems. Others involve students in one or all steps of the design cycle as they build, test, and/or redesign prototypes.
