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.

A big shout out to all the people at TLC that work so hard to bring us some really incredible professional development. The material is cutting-edge and participated are eager to learn about it and make changes happen. TLC professional development has brought about a change in pedagogy and utilization of materials. My thinking will forever be changed and challenged as a result of this opportunity. Thank you.

It was my great fortune to be introduced to the Teaching & Learning Collaborative under its previous umbrella of the Science & Math Network. Their professional development programs are simply the best to be found. Based on research and what is best teaching practice, you can be continually amazed at the high quality, active engagement and life changing experiences provided to teachers.

TLC has improved the math and science that is available to elementary students over the past several years. The short courses and educational materials that the staff have developed have given elementary teachers and administrators a better understand of math and science and some tools and skills to effectively teach math and science. The benefits received from the TLC programs have exceeded the expectations I had when we started TLC several years ago.

We have given the early childhood workshop for the past several summers in Texarkana, Texas. The teachers love the materials and enjoy using them in their classrooms.
