了解现实生活中的问题，如流感流行病学可能是特别感兴趣的科学知识的发展和启动有关病毒及其生命周期的概念变化为高中学生。该研究项目的目标是促进青少年对病毒和流感生物学的概念性理解。因此，该项目包括两个组成部分：1）前和后测试，以确定学生对流感生物学，流行病/大流行病和疫苗接种的概念;和2）设计一种干预措施，支持概念的变化，以促进基于这些基本概念的流感知识的提高。来自高中生物班的35名女学生参加了一系列的教学活动和前后测评估。前测结果显示，高中生对病毒相关概念的理解有限。在促进主动学习的干预措施实施六周后，后测结果显示，有关流感的概念与所提供的科学知识更准确地相关。虽然青少年有非科学的模型来解释流感生物学，但我们表明，精心设计的干预措施可以影响学生的知识，并影响中学健康教育计划的实施。
Understanding real-life issues such as influenza epidemiology may be of particular interest to the development of scientific knowledge and initiation of conceptual changes about viruses and their life cycles for high school students. The goal of this research project was to foster the development of adolescents' conceptual understanding of viruses and influenza biology. Thus, the project included two components: 1) pre- and posttests to determine students' conceptions about influenza biology, epidemics/pandemics, and vaccination; and 2) design an intervention that supports conceptual change to promote improvements in influenza knowledge based on these primary conceptions. Thirty-five female students from a high school biology class participated in a series of instructional activities and pre- and posttest assessments. Results from the pretest indicated that high school students exhibit a limited understanding of concepts related to viruses. Six weeks after an intervention that promoted active learning, results from a posttest showed that conceptions about influenza are more accurately related to the provided scientific knowledge. Although adolescents have nonscientific models to explain influenza biology, we showed that a carefully designed intervention can affect students' knowledge as well as influence the implementation of health education programs in secondary schools.
