INTERNET NEUROSCIENCE RESOURCE - PHASE II

本计划将以光碟形式向中学科学教师发放神经科学教材。评估这些材料的目的是：1)确定学生对科学态度的变化；2)评估学生对神经科学概念知识的变化；3)量化学生和教师如何使用互联网神经科学资源。本研究将使用科学态度量表来评估中学生在接触神经科学资源前后对科学的态度。中学生将进行前测和后测，以评估神经科学相关概念和原理的内容知识。组成内容评价清单的问题将根据美国科学促进会（1993年）、国家研究委员会（1996年）和国家科学教师协会（Aldridge和Strassenburg， 1995年）制定的指导方针和基准。在总体分布前，对中学生态度知识和内容知识的前测和后测进行效度和信度评价。网络版的神经科学资源将继续提供。对日常使用日志文件的在线调查和分析将决定如何利用互联网神经科学资源。

This project will disseminate neuroscience materials to secondary school science teachers via a CD-ROM. These materials will be evaluated to 1) determine changes in student attitudes toward science; 2) to assess changes in student knowledge of neuroscience concepts and 3) to quantify how students and teachers are using the Internet Neuroscience Resource. The Scientific Attitude Inventory-II will be used to evaluate middle school student attitudes toward science before and after exposre to the Neuroscience Resource. Pretesting and posttesting of middle school students will be performed to evaluate content knowledge of neuroscience-related concepts and principles. Questions that comprise the content evaluation inventory will be based on the guidelines and benchmarks established by the American Association for the Advancement of Science (1993), the National Research Council (1996) and the National Science Teachers Association (Aldridge and Strassenburg, 1995). Prior to general distribution, pretests and posttests for both attitude and content knowledge will be evaluated for validity and reliability with pilot group of middle school students. An Internet version of the Neuroscience Resource will continue to be available. An on-line survey and analysis of daily use log files will determine how the Internet Neuroscience Resource is utilized.
