Performance expectationUse a computer simulation to model the impact of proposed solutions to a complex real-world problem with numerous criteria and constraints on interactions within and between systems relevant to the problem.
Every item written to HS-ETS1-4 has to assess all three dimensions together, not the content alone. This is the structural change that made older practice material stop matching the exam.
Using Mathematics and Computational Thinking
What a student at each level can do with HS-ETS1-4. These drive how a cluster spreads difficulty across its items.
Summarised by ScienceIQ from the NYSED Performance Level Descriptions for Physical Science: Chemistry. These are our wording, not the Department’s — the official descriptions are the authority.
Identify the impact of a given solution to a complex real-world problem.
Use data to identify a solution impact or system interaction.
Use simulation data to describe impacts of proposed solutions with criteria and constraints.
Use a computer simulation to model impacts of proposed solutions on interactions within or between systems.
Phenomenon stimulus, connected items across the required types, answer key, rubric and figures drawn deterministically from a structured spec — in the format your students will sit.
