In our freshman Chemistry laboratory course at Nicholls State University, tutorials (with embedded quizzes) are used as pre-lab assignments. The text and graphical information provide a sufficient basis to answer all the questions, but YouTube videos are embedded for students who may need additional help. The tutorials could be easily adapted for flipped instruction in high school and college lecture courses.
