I think this is a great review for students in the Chemistry classroom. I think it would be beneficial for students to have a second chance if they chose the wrong response in the review and have the explanation as well so that they are seeing the material again to help reinforce. If this was used as a review to material that was covered in a unit, this StAIR would cover the bases. If being used as a tutorial or an introduction or larger review, it may help to present the material is a few different ways or have a video explaining one of the concepts. I thought the sound affects for right and wrong answers were great. It was a good idea to include the explanation if the student got the wrong answer.
There were a few technical issues when I opened the PowerPoint. Some of the hyperlinks within the presentation were out of order or did not advance to the appropriate slide. When I clicked on Begin, it took me to the answer about the group Oxygen belongs to. Also the atomic weight of Carbon Monoxide remained on the same slide if you chose the correct answer, it would only advance if you chose one of the wrong answers.But other than that, great resource!
