Here's a small lesson and practice session on If-Then statements. The educational theory is based on a mixture of objectivist and constructivist learning theories. The first section consists of a brief lecture, outlining how an If-Then statement works (thus serving as the objectivist part, as it defines a specific correct definition). The second, constructivist section allows for students to practice the lesson by creating their own If-Then statements. Notice that the play session responds to incomplete if-then statements, as well as when two or more statements are on the same side.
