Visual Aids

Low- or high-tech materials used to supplement written or spoken elements in lessons. Low-tech visual aids include materials like word walls, magazine cut-outs, realia, and graphic organizers. High-tech visual aids include materials like video, blogs, wikis, and video chat.

Visual Learners

Learners who benefit more from visual stimulation. Visual learners learn best when they see, as opposed to when they hear. The implication for ESL teaching is that visual stimulation accompanying lessons may have some benefit for some students.


A sound feature produced by the vibration of the larynx (vocal cords). Sounds are voiceless when vibration is absent. For example, If you have your students touch their larynx at the same time as saying /z/ or /v/, they will feel a vibration. On the other hand, if they say /s/ or /f/, no vibration will be felt. All English vowels are voiced, but some consonants are voiced while others are not.
