Web activities that support a chosen strategy and focus are essential for productive treatment/lesson activities. Materials may be more effective if they are centered around context (word relationships), events in a sequence, and dialogue. It may be very helpful to use visuals that allow the educator to check for meaning throughout a lesson. Verbal responses may sometimes be misleading if they are correct but simply echoed or picked randomly from choices offered. Visuals should be clear and iconic. Careful use of redundancy of images and lesson structure can enhance understanding and recall. Response choices that are errorless may also promote learning. Verbal aspects should match the learners developmental level. Audio and video components may be distracting or too complex. Use of computer and tablet screens may help to simplify presentation and increase engagement. Corresponding transition activities should follow for transfer of skills to face-to-face interaction. Errorless when possible.
