Ending Week 1 in the best possible way…8th graders walking over to welcome our kindergarten learners and gifting them their first spirit wear, hard to tell which group loved it more! #YouBelongInD12

Mr. Rogers taught us that curiosity opens the door to understanding. Our support teams at Spring Hills are ready to guide students on that journey. #YouBelongInD12

It’s been quite a week for our family. Harrison Francis Salsinger arrived three weeks early on July 20. From a few days in the NICU to now adjusting to life at home, he is already so loved. My family continues to grow in the sweetest of ways!

@ENassis @MarzanoResource I’m sure HE was the one impressed!

What an incredible learning experience attending the Marzano Mastery Approaches Institute...AND after 15 years of learning from @MarzanoResource I finally met Dr. Marzano himself! #MarzanoInstitute #MasteryLearning

@illinibri Congratulations you crazy kids!

June 25, 1988 was a great day! 37 years later!

What separates good teaching from great teaching? Effective feedback. Hattie’s research tells us that feedback has an effect size of 0.70—almost double the average. But not all feedback is equal. According to Hattie, “The most powerful single influence on achievement is feedback…but it must be timely, specific, and help the learner know where to go next.” Dylan Wiliam expands on this with his five strategies for formative assessment. He reminds us that feedback should cause thinking, not compliance. If students are not using feedback to move their learning forward, it’s just noise. Susan Brookhart emphasizes that feedback must be clear, purposeful, and aligned with the learning target. Vague praise or criticism does little. Students need to understand what they’re doing well, where they need to improve, and exactly how to do it. Grant Wiggins said, “Feedback is not advice, evaluation, or judgment. It’s information about how we’re doing in our efforts to reach a goal.” In short—feedback should not end the learning—it should ignite it. And let’s not forget Carol Dweck, who teaches us that how we frame feedback impacts whether students develop a fixed or growth mindset. If we want students to persist through challenges, our feedback must reinforce the process, not just the person. So in your classroom: •Make learning goals clear •Give feedback during the learning, not after •Use student work and peer feedback to promote ownership •Keep the focus on progress and next steps Great classrooms are built on a culture of feedback—where students don’t just hear it, they act on it. @VisibleLearning @dylanwiliam @SusanBrookhart @CarolDweckDSU

Congratulations to our 2025 8th-grade graduates! We are proud of you and know you will go on to great things! #YouBelongInD12
