[Research](https://info.teachstone.com/blog/topic/research) - [Coach Tips](https://info.teachstone.com/blog/topic/coach-tips) - [Products and Trainings](https://info.teachstone.com/blog/topic/products-and-trainings) ![](https://info.teachstone.com/hs-fs/hubfs/Coaching%20Instructional%20Support.png?width=519&height=300&name=Coaching%20Instructional%20Support.png) Georgia's [Department of Early Care and Learning (DECAL)](http://decal.ga.gov/) has released a report on the impact of two professional development, CLASS®-based coaching programs, [Making the Most of Classroom Interactions](https://teachstone.com/class-group-coaching/) (MMCI) and [MyTeachingPartner](https://teachstone.com/1-1-video-coaching/) (MTP), in pre-K classrooms across the state. And guess what? Both programs led to increases in teachers’ CLASS® scores. What's more is that the teachers enjoyed their experiences with the programs. I love research, but I realize that not everyone wants to dig into an in-depth report or a [technical appendix](http://decal.ga.gov/documents/attachments/GAPreKProvDevEval_TechnicalAppendix.pdf), so below is the summary for your reading pleasure. You can also read the full report [here](http://decal.ga.gov/documents/attachments/GAPreKProvDevEval_Report.pdf). --- *One thing to note before diving into the results: since this study was published, the names of the coaching programs have changed. Making the Most of Classroom Interactions (MMCI) is now called CLASS® Group Coaching. And, MyTeachingPartner (MTP) is called 1-1 Video Coaching. While the names have since been updated, the processes and effectiveness have not changed. * --- ## **Things to Know About the Three-Year Georgia Study of MMCI and MTP** ### **Researchers posed two key questions:** - Were the MTP and MMCI interventions effective in improving teacher-child interactions in pre-Kindergarten classrooms? - How were the interventions perceived by Georgia’s Pre-K consultants and teachers? ### **What did they find?:** - Both programs were effective and well-perceived! - Emotional Support increased as a result of participation in MTP, as compared to the control group. - Emotional Support *and* Instructional Support increased as a result of participation in MMCI, as compared to the control group. - Teachers favorably rated participation in MTP and MMCI, as compared to the control group. ### **Why is this study so powerful and downright cool?:** - Researchers used a control group. Huh? What’s a control group? In research, a control group is a group that closely resembles the “treatment group” (in this case the group receiving MTP or MMCI) but doesn’t receive the treatment so that it can serve as a comparison when the results are evaluated. - Participants were randomly assigned to three groups: MTP, MMCI, and control. More on the control group thing: random assignment creates similar groups, thus any effect observed among intervention groups can be linked to the intervention effect and is not a characteristic of the individuals in the group. For example, if I opted into the MTP program because I wanted to work with a coach, it would be difficult to tell if my own excitement and motivation due to my choice impacted my CLASS scores or if it was due to the intervention itself. - This kind of field study is incredibly difficult to undertake, so we are grateful for the careful work of Georgia DECAL, Frank Porter Graham, and Child Trends. ### **So why should I care?:** - Almost every day we get questions about how to "scale" professional development programs. This report shows that MTP and MMCI deliver impact on a large scale. - We also talk a lot about "dosage," or just how much of an intervention it takes to create change. For instance, participants in the DECAL study attained fewer MTP cycles than those in the initial development study. An interesting fact is that our MTP participants in California achieved an average of 13.86 cycles last year. We will be studying these implementation models to draw important lessons. Indeed, is there a minimum, maximum, or the ideal number of MTP cycles that yield the greatest change in teacher practice, as is asked in the GA study? Stay tuned. All this to say, we realize that implementing meaningful professional development is not easy—and there certainly is no magic wand (wouldn’t it be cool if there was?). In Georgia, it took a big commitment: time, valuable human capital, finances, training, and technology. But how rewarding to see it pay off! Congratulations to our partners at Georgia DECAL and all of the coaches and teachers who did the truly hard work to get these results! Want to learn more about Teachstone's coaching programs?
