Cancer Narratives for Low-Literacy Adult Learners

描述(申请人提供)：该项目旨在帮助低识字率的成年人了解有关结肠癌的信息，并为自己采取行动。第一阶段将确定为识字率低的学习者制作交互式多媒体系统的技术可行性，并将对25名学习者进行有目的的抽样，评估其效果。课程和多媒体演示的设计以社会学习理论为基础，将直接教学和基于叙事的教学相结合。直接教学使用文本、插图和可选的音频来呈现材料。叙事技术采用故事，通过人物、对话和情节传达信息，并可选择音频来叙述故事。第一阶段的目标是：a)根据与预防结肠癌有关的特定期望行为改变制作一个原型CD-ROM；b)评估学习者对CD-ROM的可用性、教师对CD-ROM的满意程度，以及通过使用CD-ROM促进学习者期望的行为改变的程度。这些材料的重点是每天至少吃5份水果和蔬菜，知道一份的份量是多少，并限制水果和蔬菜中高脂肪的添加。第一阶段的评估活动在Project Read中进行，Project Read是加州一家基于图书馆的成人学习服务机构。

DESCRIPTION (provided by applicant): The proposed project aims to help low-literacy adults understand information on colon cancer and take action for themselves. Phase I will establish the technical feasibility of producing an interactive multimedia system for low-literacy learners and will evaluate its effectiveness on a purposive sample of 25 learners. The design of the curriculum and multimedia presentation is based on principles of social learning theory and combines direct and narrative-based instruction. Direct instruction uses text, illustrations, and optional audio to present material. Narrative techniques employ stories that convey information via character, dialogue and plot, with optional audio to narrate the story. Phase I objectives are to a) produce a prototype CD-ROM based on specific desired behavior change related to colon cancer prevention, and b) evaluate the usability of the CD-ROM by learners, the tutors' level of satisfaction with the CD-ROM, and the extent to which the desired behavior change in the learner has been promoted by the use of the CD-ROM. The material will focus on eating at least 5 fruit and vegetable servings each day, knowing what a serving size is, and limiting high-fat additions to fruits and vegetables. Phase I locates its evaluation activities within Project Read, a library-based adult learning service in California.
