本论文主要针对来自少数民族和低社会经济地位背景的中学生进行为期两年的STEM干预的描述和评估。来自低收入和少数民族背景的中学生（n = 166）参加了为期两年的强化实践科学和技术干预，以提高他们对生物医学和健康科学的兴趣。定量和定性数据收集自TRY-IT！学生以及没有参与干预的对照组、教师和家长评估他们对各种stem相关主题的态度和知识的变化。定量分析没有显示TRY-IT！和对照组，从而对干预的有效性提供了一个混合评估。然而，在参与第二年收集的定性学生回答显示出对项目经验和他们接触科学的好处的积极态度。根据这些发现，从规划和实施研究过程中所经历的成功和挑战的反思中得出的见解为指导未来的计划和研究提供了指导。该干预措施是针对STEM职业中少数民族和低社会经济地位个体的持续代表性不足而开发的。考虑到这一职业领域与其他领域相比，对未来几代人来说前景光明，努力提高对科学和数学的积极态度，以及对STEM职业在这一人群中的可及性的信心是很重要的。
The current paper focuses on the description and evaluation of a two-year STEM intervention targeting underserved middle schools students from minority and low SES backgrounds. Middle school students from low-income and minority backgrounds (n = 166) were targeted to participate in a two-year, intensive, hands-on science and technology intervention to increase their interest in biomedical and health sciences. Quantitative and qualitative data were collected from TRY-IT! Students as well as a control group that did not participate in the intervention, teachers, and parents to assess changes in attitudes and knowledge with respect to a variety of STEM-related topics. Quantitative analyses did not reveal significant long-lasting differences between the TRY-IT! and the control group, thus providing a mixed assessment of the effectiveness of the intervention. However, qualitative student responses collected during the second year of participation revealed positive attitudes toward the program experience and benefits of their exposure to science. In light of these findings, insights drawn from reflecting on successes and challenges experienced during the course of planning and implementing the study are provided to guide future programs and research. The intervention was developed in response to the continued under representation of minority and lower SES individuals in STEM careers. An effort to boost positive attitudes toward science and math, as well as confidence in the accessibility of STEM careers among this population is important given the promising outlook of this career field compared to others for future generations.
