The document summarizes two studies that evaluated educational technology: The first was a comparative study that examined student learning and perceptions in a horticulture course delivered either via live instruction or web-based instruction. Surveys found that while both groups improved their quiz scores, the increase was greater for students who received live instruction. The second was a non-comparative study that investigated how learning styles, computer skills, and prior online course experience influenced knowledge gain for adults in an online special education course. The study found that identifying individual differences like learning styles and computer abilities can help optimize online course design and address diverse student needs.
