LENS Project Cornerstone Assessments
The Learning Enhanced through the Nature of Science (LENS) project is an innovative professional development program for high school Earth science, biology, chemistry, and physics teachers.
The Cornerstone Assessments are a product developed as a part of the project. A team of secondary science teachers, science curricular and methods experts, and cognitive psychologists developed the Cornerstone Assessments as a part of the LENS project.
The LENS Cornerstone Assessments were created as a result of a Mathematics and Science Partnership Grant to Old Dominion University in partnership with local school divisions and partner institutions of higher education. The assessments were developed by a team of secondary science teachers, science curricular and methods experts, and educational psychologists, the assessments are an invaluable tool for measuring the development of secondary students' science skills.
The Cornerstone Assessments use knowledge and skills related to scientific investigation to inform instruction, inform student learning, and measure student progress over time (beginning-, middle-, and end- of the year). The Cornerstone Assessments are available for use if they meet the needs of your students.
The multimedia tutorials were developed for teachers and administrators to define and explain the purpose of the LENS Cornerstone Assessments and to suggest ways the assessments can be used in the classroom to improve student learning and performance.
The following modules will help you understand:
Module 1 – Why the LENS Cornerstone Assessments were created?
Module 2 – What is a LENS Cornerstone Assessment, and what it’s not?
Module 3 – How science teachers can use LENS Cornerstone Assessment data to evaluate or differentiate?
Module 4 – How to enhance classroom instruction using LENS Cornerstone Assessments?
LENS Cornerstone Assessment Sample Resources
The following sample files have been added to help clarify key components of the Cornerstone Assessments that are available for teachers, schools, and school divisions.
Part A (PDF) provides the student an opportunity to describe an experimental design based on a scenario provided.
Part B (PDF) provides the students an opportunity to respond to questions related to Part A in terms of data analysis and scientific reasoning. These are only samples of the two-part Cornerstone Assessment and not the actual assessment.
Each assessment has an associated rubric (PDF). This rubric should be used to score the student responses for each part of the Cornerstone Assessment.
