Many modern technological advances have direct impact on the format, style and efficacy of delivery and consumption of educational content. For example, various novel communication and information technology tools and resources enable efficient, timely, interactive and graphical demonstrations of diverse scientific concepts. In this manuscript, we report on a meta-study of 3 controlled experiments of using the Statistics Online Computational Resources in probability and statistics courses. Web-accessible SOCR applets, demonstrations, simulations and virtual experiments were used in different courses as treatment and compared to matched control classes utilizing traditional pedagogical approaches. Qualitative and quantitative data we collected for all courses included Felder-Silverman-Soloman index of learning styles, background assessment, pre and post surveys of attitude towards the subject, end-point satisfaction survey, and varieties of quiz, laboratory and test scores. Our findings indicate that students' learning styles and attitudes towards a discipline may be important confounds of their final quantitative performance. The observed positive effects of integrating information technology with established pedagogical techniques may be valid across disciplines within the broader spectrum courses in the science education curriculum. The two critical components of improving science education via blended instruction include instructor training, and development of appropriate activities, simulations and interactive resources.
许多现代技术进步对教育内容的传递和消费的形式、风格及效果都有直接影响。例如,各种新颖的通信和信息技术工具及资源能对多样的科学概念进行高效、及时、互动且直观的展示。在本论文中,我们报告了一项针对概率与统计课程中使用在线统计计算资源(Statistics Online Computational Resources,SOCR)的3个对照实验进行的元研究。在不同课程中,将可通过网络访问的SOCR小程序、演示、模拟和虚拟实验用作教学手段,并与采用传统教学方法的匹配对照班级进行比较。我们为所有课程收集的定性和定量数据包括费尔德-西尔弗曼-所罗门学习风格指数、背景评估、对该学科态度的前后调查、终点满意度调查以及各类测验、实验和考试成绩。我们的研究结果表明,学生的学习风格和对一门学科的态度可能是其最终量化表现的重要干扰因素。将信息技术与既定教学技术相结合所观察到的积极效果,可能在科学教育课程更广泛范围内的各学科中都有效。通过混合式教学改善科学教育的两个关键要素包括教师培训以及开发合适的活动、模拟和互动资源。
