Hey! My first introduction to software engineering was via HyperCard in an advanced elementary school math class in the Texas public school system in the early 90s. I have made a nearly 30 year career out of the passion my teacher and a volunteer parent sparked in that class.
Mine as well (well, not in Texas). I have fond memories of building a bunch of simple adventure games with my classmates - it was incredibly easy to learn how to use the authoring tools.
