I.E.S. Cognition and Student Learning in Special Education (
Students who are deaf or hard of hearing (d/hh) perceive and understand the world via the use of both their language (ASL, English) and their interpretation of visual images (pictures, animation). As a result, regardless of the educational philosophy or communication modality being used, educators have the responsibility to present targeted academic knowledge and skills in a manner that their students can effectively perceive and understand. Such presentation includes the ability to effectively develop and use multimedia representations (print, narration, pictures and animation) to convey targeted academic knowledge and skills.
Lang (2005), in a review of literature concerning the science education of students who were d/hh, noted studies related to multimedia presentation. Deibold and Waldron (1988) found that highly pictorial content with simplified English text produced significantly higher pre- to posttest gain scores than formats with less pictorial content and more complex English patterns in the text.
Dowaliby and Lang (1999), found that the combination of text with pictures, signs, and/or adjunct questions all resulted in significant gains in immediate factual learning over text alone, with adjunct questions accounting for the most gain. Lang and Steely (2003) found that interactive multimedia yielded significantly greater knowledge gains for deaf students as compared to traditional classroom experiences, suggesting that appropriate arrangement of text, ASL explanations and pictorial input from animation and graphic organizers can allow instructional programs for hearing students to be effectively adapted for use by students who are d/hh. As early as 1980, Reynolds and Booher found that instructional materials that were predominantly pictorial with ancillary verbal information were the most effective for deaf college students at that time.
A summary analysis of the cited research indicates that learning of individuals who are d/hh can be significantly enhanced when they are actively engaged in the comprehension and use of effective multimedia representations of key academic information.
While the importance of student engagement and effective multimedia representations for students who are d/hh has been consistently stated (Stewart & Kluwin, 2001; Moores & Martin, 2006), investigations have not been carried out concerning the extent to which teachers of students who are d/hh either have access to, or use, academic curricular material that incorporates effective multimedia design. This lack of empirical investigations is at least partially due to the complexity entailed in identifying the specific principles of an effective multimedia design.
Fortunately, Mayer (2001, 2009) has carried out an extended series of studies identifying multimedia principles that facilitate both recall and transfer of targeted information. He begins with the assumption that the learner has a finite capacity to store either pictorial information or verbal information, but eventually integrates the two during the learning process. The following visual summarizes Mayer’s findings through 2001.
However, Mayer’s research has potential limitations for the population of students who are d/hh. He worked entirely with individuals with typical hearing, only a few of whom were children. Pictorial information usually enters through the visual channel, but verbal information can enter initially though the auditory channel (speech, narration) or the visual channel (text, signed language) before being processed through the language centers of the brain and then integrated with the visual information. The process is complex, and needs to be investigated with children who are deaf or hard of hearing. However, the work cited earlier suggests that multimedia based instruction and multimedia principles have validity with this population.
Using Mayer’s principles, an initial research direction would be the examination of curriculum materials currently in use to teach math and science to children who are deaf or hard of hearing. To what extent do the materials conform to Mayer’s principles? Based on qualitative analysis of the materials through an evaluation rubric, we can make predictions about their effectiveness, and test those predictions in the second stage of the proposed research studies. During the second stage, the group can develop research models for students who are d/hh, and set up individual studies across a widely heterogeneous population of students who are d/hh. New predictions about the effectiveness of the principles, as well as needed modifications, based on this expanded population can then be tested in real classroom environments.
