Because textbook publishers are sensitive about releasing sales figures, we are unable to determine the quality of popular texts compared to the quality of less popular text. Knowing the type(s) of reference works you or your children use in the classroom will help us greatly in this effort. Please fill out the following form and send it to us. All of your responses are highly appreciated.
Additionally, if there are any materials we failed to include in our study, please record them on the form below. Feel free to include as many titles as you wish by simply filling out the form, sending it, and filling it out again.Thank you.
