Nonprofit Overview

Causes: Education

Mission: To provide innovative, high-quality professional development and support for preK-12 educators in mathematics, science, and technology.

Results: TLC coordinates several professional development programs in mathematics and science. For the past six years, TLC has coordinated the statewide K-3 IMPACT program. IMPACT helps teachers develop instructional methods which provide all of their students with skills that will lead to future successes in STEM careers. K-3 IMPACT instruction is student-centered and develops the critical foundations in number sense, measurement and problem-solving. Many of the participating teachers are working in schools that serve a high percentage of economically disadvantaged students. Skills developed in this program lead to better intervention with these students so they have a solid mathematical understanding in the early grades. The intention of K-3 IMPACT is to lead to student success which is a shared goal of programs such as Closing the Achievement Gap. K-3 IMPACT was developed by a statewide group of mathematics leaders. It is managed by the Teaching & Learning Collaborative in partnership with Educational Service Centers and universities. To date, almost 400 different schools have participated in the first four years of IMPACT, represented by approximately 1,500 teachers. Eevaluation results have consistently demonstrated K-3 IMPACT's value as a strong well-received professional development experience for K-3 teachers. Results have shown that K-3 IMPACT participants have made statistically significant gains in mathematics content knowledge and improved instructional techniques.

Target demographics: Educators in grades PreK-12

Direct beneficiaries per year: Hundreds of teachers attend TLC programs each year. This summer alone, TLC worked with over 350 teachers who will work with almost 10,000 students.

I have had an amazing experience with the TLC group and their IMPACT program. I have teamed up with them to deliver high quality math professional development for elementary teachers. Every session is well planned and expertly produced. The availability of the team for guidance is unmatched. They are amazing!!!!

I have taken workshops with the group. All that they provide is current, research-based PD. The facilitators are outstanding getting us to stretch our thinking and learning. Math PD is what I typically attend. There is very little PD in elementary ed that is centered around Common Core, so their IMPACT workshops, Pre-K Counts, K-5 Structures are amazing and timely!

I have worked with TLC since 2005. I have helped them with mathematics education by serving on advisory boards and rewrite committees. If you are looking for the most current information on mathematics and science education, this is the place to get your training! They use the most current research to create workshops. The focus is always on building teacher's content knowledge. Absolutely the best group to get your latest and greatest on Ohio's New Learning Standards!
