Program developers make choices and iterate to continually refine their product. At this stage, students explain or write about the goals and expected outcomes of the programs they create and the choices that they made when creating programs. Students could use coding journals, discussions with a teacher, class presentations, or blogs. For example, students could use a combination of images, verbal reflections, a physical model, and/or written text to show the step-by-step process taken to develop a program such as cutting and pasting coding commands into a journal, using manipulatives that represent different commands and control structures, and taking screenshots of code and adding to a digital journal. This iterative process could be documented via a speech, journal, one on one conference with teacher or peer, small group conference, or blog.
