What Educators are Saying
Real feedback from educators using TechBox.
"My students had such a great time with their Tech Boxes. Many, were so excited to accomplish the task that they were ready to take them home to continue the lesson.
You know what else was cool? All the kids who were running around after the lesson with Tech Boxes in their arms bragging to other students and fielding questions about them - they were so excited and proud!"
"TechBox offered the hands-on interactive & educational component to Centre College's high school STEM camp that we needed! The Laser Stem Matrix introduced the students to wiring bread boards and programming, and it sparked the interest of some potential engineers in the group! With a range of exposure to technology and electronics, TechBox was able to meet the needs of everyone - from the beginner to the experienced. The instructions were easy to follow and offered educational lessons throughout for those who had less experience."
