Analyzing the Use of C-Print Mobile Technology in STEM Lab Settings across Multiple Postsecondary Sites

《分析C-Print移动技术在多个专上地点的STEM实验室设置中的使用情况》是基于之前在C-Print移动技术方面的工作，该技术由美国国家科学基金会残疾教育研究计划(0726591奖)资助，该计划使聋人或重听学生能够在主流大学STEM课程中获得语音到文本(字幕)的支持服务。拟议项目的两个目的是(1)将这项服务(C-Print Mobile软件)的使用场所类型扩大到其他几所大学、一所社区学院，以及有RDE资助的STEM残疾学生联盟的机构；以及(2)进行实验调查，以评估这项服务在多大程度上帮助学生在STEM实验室进行中学后阶段的学习。研究目标是考察C-Print Mobile的使用对STEM课程实验室部分d/hh学生的学习成绩以及他们对STEM专业的信心和兴趣的影响。与听障或重听学生有关的研究问题包括：1.C-Print Mobile对实验室和整个课程表现有什么影响？2.C-Print Mobile对STEM兴趣维度有什么影响？3.学生特征和对Co-Print Mobile功能的使用是否与实验室和课程表现有关？4.学生特征和对特征的使用是否与STEM兴趣的特定维度有关研究参与者被随机分配到两组之一：(A)C-Print Mobile干预组，或(B)常规服务继续控制组，采用2(支持：C-print Mobile与标准支持服务，受试者间因素)×2(类别：干预/对照类别与可比类别，受试者内因素)混合方差分析设计。在这两个条件中都包括一个标准服务“基线”，这将使学生能够在学科内比较使用和不使用C-Print技术的学生的表现和自我评级，这将有助于确定有效性。相关研究将包括对字幕准确性的研究，目的是确定服务提供商在实验室环境中可以达到的准确程度，以及观察字幕员和学生使用C-Print Mobile的情况。观察的目的是获得与向学生提供C-Print Mobile服务和学生使用该服务有关的信息。此外，还将与讲师和字幕作者进行面谈，以发现关键的执行问题，这些问题将为扩大和传播工作提供信息。该项目团队将与三个合作机构合作：路易斯安那州立大学、威斯康星大学密尔沃基分校和布里斯托尔社区学院。RDE资助的STEM残疾学生联盟中的五个将进行合作，包括纽约(Mind)、缅因州(EAST2)、俄亥俄州(OSAA)、华盛顿(AcessSTEM2)和威斯康星州(中西部)的联盟。如果发现积极的结果，授精活动将涉及C-Print Mobile扩大规模的信息。该项目的外部评估者是鲍林格林大学研究生院副院长Martha Gaustad博士。项目的外部评估者是鲍林格林大学研究生院副院长Martha Gaustad博士。她将提供形成性评价，作为正在进行的项目评估和改进的基础，并提供总结性评价，以确定项目实现其目标的程度。

"Analyzing the Use of C-Print Mobile Technology in STEM Lab Settings across Multiple Postsecondary Sites" is based on previous work on C-Print Mobile technology which was funded by the NSF's Research in Disabilities Education (RDE) program (Award 0726591) which enables deaf or hard of hearing (d/hh) students to receive speech-to-text (captioning) support services in mainstream college STEM courses. The two purposes of the proposed project are to (1) expand the types of venues in which the service (C-Print Mobile software) is used to several other universities, a community college, and institutions with RDE-funded Alliances for Students with Disabilities in STEM; and to (2) conduct experimental investigations to evaluate the extent to which the service aids students' access and learning in STEM labs at the postsecondary level. The research goal is to examine the effects of the use of C-Print Mobile on the academic performance of d/hh students in laboratory sections of STEM courses and on their confidence and interest in their STEM major. Research questions related to STEM students who are deaf or hard of hearing include: 1. What are the effects of C-Print Mobile on laboratory and overall course performance?2. What are the effects of C-Print Mobile on dimensions of STEM interests?3. Do student characteristics and use of features of Co-Print Mobile relate to laboratory and course performance?4. Do student characteristics and use of features relate to specific dimensions of STEM interestsResearch participants are randomly assigned to one of two groups: (a) a C-Print Mobile intervention group, or (b) a continuation of regular services control group, yielding a 2 (Support: C-Print Mobile vs. standard support service, a between subjects factor) X 2 (Class: intervention/control class vs. comparable class, a within subjects factor) mixed ANOVA design. The inclusion of a standard service "baseline" in each of the two conditions will allow for within-subject comparisons of students' performance and self-ratings with and without the C-Print technology will contribute importantly to determination of effectiveness. Related studies will include research on captioning accuracy for the purpose of determining the level of accuracy that a provider of services in a laboratory setting can achieve, and the observation of captionists' and students' use of C-Print Mobile. The observations will be designed to obtain information pertinent to provision of C-Print Mobile services to students and the use of the service by students. In addition, instructors and captionists will be interviewed to discover critical implementation issues that will inform scale-up and dissemination efforts. The project team will work with three partnering institutions: Louisiana State University, the University of Wisconsin-Milwaukee, and Bristol Community College. Five of the RDE-funded Alliances for Students with Disabilities in STEM will collaborate, including the Alliances in New York (MIND), Maine (EAST2), Ohio (OSAA), Washington (AcessSTEM2)and Wisconsin (MIDWEST).Dissemination activities will involve information for scale-up of C-Print Mobile if positive results are found. Websites, professional presentations and publications, outreach to RDE Alliances and other practitioners, and C-Print training will provide avenues to broaden the participation of d/hh students in STEM education.The project's external evaluator is Dr. Martha Gaustad, Associate Dean of the Graduate College at Bowling Green University. She will provide formative evaluation as a basis for ongoing project assessment and improvement and summative evaluation to determine the extent to which the project has met its goals.
