The Center on Instruction hosted a WebEx on November 6, 2007, for Regional Comprehensive Center staff, to discuss two recently released math resources. Author Dr. Ben Clarke presented Screening for Mathematics Difficulties in K-3 Students. Authors Dr. Erica Lembke and Dr. Pam Stecker presented Curriculum-Based Measurement in Mathematics: An Evidence-Based Formative Assessment Procedure. This webinar supports using screening and progress monitoring to improve student achievement in mathematics for implementation of School Improvement Grants (SIG) requirements. The PowerPoint presentation from the meeting is available below. The archived WebEx is also available here. The two documents are also available for download below, or from our resources section.
