Please refer to OpenSciEd Unit and Lesson Level Documentation:
A lesson-level performance expectation (LLPE) is a three-dimensional learning statement for each lesson aimed at highlighting the key student expectations for that lesson. Every OpenSciEd lesson includes one or more LLPEs. The structure of every LLPE is designed to be a three-dimensional learning, combining elements of science and engineering practices, disciplinary core ideas and cross cutting concepts. The font used in the
LLPE indicates the source/alignment of each piece of the text used in the statement as it relates to the NGSS dimensions: alignment to Science and Engineering Practice(s) , alignment to Cross-Cutting Concept(s) , and alignment to the Disciplinary Core Ideas .
Each unit includes a table that summarizes opportunities in each lesson for assessing every lesson-level performance expectation (LLPE). Examples of these opportunities include student handouts, home learning assignments, progress trackers, or student discussions. Most LLPEs are recommended as potential formative assessments. Assessing every LLPE listed for each student can be logistically difficult. Strategically picking which LLPEs to assess and how to provide timely and informative feedback to students on their progress
toward meeting these is left to the teacher's discretion. However, the system is designed to support a quick review of the LLPE, assessment guidance, and a subset of student work to help inform instructional decisions throughout the unit even if you are not assessing each student individually every time.
