Assign content as homework that students can learn from reading (like FOR loop syntax) so you can spend class time on more difficult topics where teacher guidance is the most needed (like what code goes inside of a loop). Like(120 Likes)
Misconception: When students use the division operator during declaration or assignment of a Double in Java, like double x = a/b, they forget about integer division, which can result in rounding errors. Like(134 Likes)
