Technical Requirements Java
Comments I'm not sure if I would use this in class, simply because I don't have room in my schedule to add another topic. But in a class where it fits, it would be a good homework assignment.
Content Quality (Concerns) Many introductory statistics textbooks present normal distribution tables that give left-tail probabilities, but the p-value converter within this tutorial asks for a right-tail probability. Might that end up confusing students?
Content Quality (Strengths) Each concept is defined, and then described with an example. There is discussion about how the different measures work together. The tutorial breaks down a complex concept and explains that concept in terms that are easy for beginners to understand. There are many graphics to accompany different explanations, and students have opportunities throughout the tutorial to practice what they are learning and test themselves.
Ease of Use (Concerns) None.
Ease of Use (Strengths) It's very easy to navigate. Each page has a link at the bottom to the previous page, the index, and the next page. There are many links along the way where students can get help if they need it or more information about how to use different tools. Information is broken down into different sections and clearly labeled. There doesn't appear to be too much going on all at once on a page that might distract users or make it difficult for them to find relevant information.
Potential Effectiveness (Concerns) It might be helpful to include more "real world" examples so students can see how Signal Detection Theory applies to their every day lives. This is especially important since the overview for this tutorial notes that "Every day we have to make decisions about uncertain events." Providing more examples of such events and working through those examples might engage students. Also, it would be helpful to know more about just where this might fit into the curriculum in a course, and to see some example assignments students might be given outside of class that would use this tutorial.
Potential Effectiveness (Strengths) Offers a clear description of the concepts being discussed. The information here is very well written, and accurate instructions are provided. The tutorial includes instructor's notes for how to use this tool in a variety of different ways in and outside the classroom. The tutorial encourages students to be active participants in the learning process by providing them with many opportunities to stop and check their understanding before proceeding to other content.
