A Cluster Randomized Study of Heuristic Teaching vs. Intelligent Tutoring for Community College Students with Disabilities in Algebra

“启发式教学与智能辅导的集群随机研究社区大学生与残疾人在代数”是两个干预策略的有效性进行调查解决问题的社区大学生残疾人在小学代数I课程的表现，并坚持在干课程和学位课程。 本研究将比较一种启发式数学教学法，其内含内容独立的元认知策略（HMTM）和一种基于计算机的个性化学生干预（ITS）。 夏威夷大学社区学院将与檀香山社区学院和迎风社区学院一起参加初步选择的研究;这两所学校目前参加了NSF资助的STEM残疾学生太平洋联盟。 该设计包括使用一个随机分组试验，其中有一个对照组和重复测量。 这项研究将进行32个小学代数I类和128 SWD，重点是以下三个研究问题：RQ 1。HMTM作为一个单一的干预组成部分，在多大程度上提高了学生a）：代数I课程的完成率和B）在STEM相关课程工作的持续性？RQ 2.在多大程度上使用ITS（特别是认知导师），作为一个单一的干预组成部分，提高学生成绩的两个领域（代数I的成功完成和STEM的持久性）？RQ 3.在多大程度上使用HMTM和ITS相结合，提高学生成绩的两个领域？对该项目的独立评估将由Crystal米尔斯博士进行，他是夏威夷大学社会工作硕士课程的教授和主席，也是东密歇根大学社会工作的名誉教授。将根据总结性和形成性调查结果编写一份推广手册，详细说明项目方法和成果，并在项目网站上全面传播。论文将在专业期刊上发表。方法和结果将在国家专业会议上提出。研究结果将公布在项目网站上，并在NSF研究人员年会上发表。

"A Cluster Randomized Study of Heuristic Teaching vs. Intelligent Tutoring for Community College Students with Disabilities in Algebra" is an investigation of the effectiveness of two intervention strategies for problem solving on the performance of community college students with disabilities in an Elementary Algebra I course and persistence in STEM coursework and degree programs. A heuristic math teaching method with an embedded content independent metacognitive strategy (HMTM) and a computer based individualized student intervention (ITS) will be compared. The University of Hawai`i Community Colleges will participate in the research study with Honolulu Community College and Windward Community College targeted for initial selection; these two schools currently participate in the NSF-funded Pacific Alliance for Students with Disabilities in STEM. The design involves using a cluster-randomized trial with a control group and repeated measures. The study will be conducted with 32 Elementary Algebra I classes and 128 SWD, focusing on the following three research questions:RQ 1. To what extent does HMTM, as a single intervention component, improve student a): Algebra I course completion rate and b) persistence in the STEM related course work?RQ 2. To what extent does use of ITS (specifically Cognitive Tutor), as a single intervention component,improve the two areas of student outcomes (successful completion of Algebra I and persistence in STEM)?RQ 3. To what extent do the use of HMTM and ITS in combination, improve the two areas of student outcomes?An independent evaluation of the project will be conducted by Dr. Crystal Mills, who is Professor and Chair of the University of Hawai`i's Master of Social Work program and an Emeritus Professor of Social Work at Eastern Michigan University.The following dissemination strategies will be utilized:1. A replication manual detailing project methods and results, based on the summative and formative findings, will be prepared and comprehensively disseminated on the project website.2. Manuscripts will be published in professional journals.3. The methodology and findings will be presented at national professional conferences.4. Findings will be posted on the project website and presented at the Annual Meeting of the NSF investigators.
