WebScience: Creating an Active Learner Classroom with WWW Technology to Improve Introductory Science and Mathematics Courses

其他科学NEC(99)项目SUMMARY问题：尽管呼吁改革科学和数学教育，但大多数学生在教授讲课时被动地坐着。众所周知，这种“舞台上的圣人”教育模式不如主动学习法那么有效。因此，许多受过大学教育的人缺乏在工作场所跟上形势并参与公共辩论所需的科学素养。这个问题尤其具有破坏性，因为它影响到职前教师。教师准备不足造成了“文盲循环”，因为准备不足的教师培养了新一代准备不足的学生。目标：我们正在使用一种经过课堂测试的策略，通过万维网(WWW)在五门入门和高级课程中促进师生之间的积极学习和交流。在三年的实施期间，我们将惠及超过8000名学生，包括SMET专业的学生、职前教师和符合普通理科要求的学生。该项目的重点是增加弱学生和强学生的学习，增加留存，并提高解决问题的能力、批判性思维、团队合作和沟通技能。它还关注职前教师，让他们接触新的教学方法，并鼓励他们作为学生导师开始教学。方法：该项目是对即时教学(JITT)的大规模改造，JITT是一种将技术与主动学习相结合的系统。JITT是为IUPUI和美国空军学院的物理课程开发的，得到了NSF本科教育部门的支持(截止日期为975 2365)，截至1999年春季，已被其他12所机构采用。在这个项目中，JITT正在化学、生物和数学课程中得到改编和实施。在JITT教学法中，学生在每节课前几个小时使用WWW接收和回答预备性问题。参与的教员使用这些学生的反馈来为下一次班会组织课程。因此，学生参加的课程是基于他们自己的先验知识。JITT还利用网络提供丰富的材料，并增加学生和教师之间的互动。该项目正在与其他教职员工合作，帮助他们学习JITT系统，随着项目的成熟，该项目将进一步推动教师发展。

Other Sciences NEC (99)PROJECT SUMMARYProblem: Despite calls for reform in science and mathematics education, most students sit passively while professors' lecture. This "sage on stage" mode of education is known to be less effective than active-learner methods. As a result, many college-educated people lack the scientific literacy needed to keep up in the workplace and to participate in public debate. This problem is especially damaging as it affects pre-service teachers. Poor teacher preparation creates a "cycle of illiteracy" as underprepared teachers promote new generations of underprepared students.Objectives: We are using a classroom tested strategy that fosters active learning and communication among faculty and students in five introductory and upper division courses using the World Wide Web (WWW). During the 3-year implementation period, we will benefit over 8,000 students including SMET majors, pre-service teachers, and students satisfying general science requirements. The project is focusing on increased learning by both weak and strong students, increased retention, and improved problem-solving, critical thinking, teamwork and communication skills. It is also focused on pre-service teachers, exposing them to new pedagogies, and encouraging them to begin teaching as student mentors.Methods: This project is a large scale adaptation of Just-in-Time Teaching (JiTT), a system that integrates technology with active learning. JiTT was developed for physics courses at IUPUI and the US Air Force Academy with support from the NSF Division of Undergraduate Education (DUE 975 2365) and has been adopted at 12 other institutions as of Spring, 1999. In this project, JiTT is being adapted and implemented in chemistry, biology and mathematics courses. In the JiTT approach, students use the WWW to receive and answer preparatory questions a few hours before each class. Participating members of the faculty use these student responses to structure lessons for the next class meeting. Thus, students participate in a class that is based on their own prior knowledge. JiTT also uses the web to deliver enrichment materials and to increase interaction among students and faculty. The project is working with other members of the faculty to help them to learn the JiTT system, and the project will institute further faculty development efforts as the project matures.
