A preservice teacher with a solid CS background remarked a couple of weeks ago about the maturity of junior secondary students to think about coding and computational thinking (CT), remarking that there are many pedagogical and maturity challenges. I have been reading up about CT and the benefits to students, even if they don't go on to study CS.</p><div class="csl-bib-body" style="box-sizing: border-box; caret-color: rgba(0, 0, 0, 0.870588); color: rgba(0, 0, 0, 0.870588); font-family: roboto, "Helvetica Neue", Arial, sans-serif; font-size: 16px;"><p class="csl-entry" style="box-sizing: border-box; margin-top: 0px; margin-bottom: 1rem; margin-left: 30px;">Lu, J.
