I feel as though this is a completely ineffective decision and will prove to be more of a detriment to student progress than an aide. Though we live in an age where technology is used in everyday life, it is still necessary to understand the fundamental components of writing. Additionally, this creates an unfair discrepancy between those taking the test online and those taking the paper version. Though a dictionary can be helpful, it will not recognize errors for the students as a spell-check program would. In other words, the student would have to know that the word is spelt wrong in order to look it up. In my opinion, this will create an array of completely unreliable test scores.
Technology can be very helpful in the classroom and is now necessary for students to use. However, applying technology to standardized testing in this way will not help to demonstrate anything that the student knows. Instead using spell check on these tests will simply show that they student understands how to use the spell-check function on the computer.
