The main purpose of this quantitative study was to examine the degree to which a three-week intervention in an urban high-needs high school science classroom would influence students’ (n = 51) interest, utility value, content knowledge, and intentions for future study in chemistry. The intervention consisted of an authentic, inquiry-based chemistry project where students worked cooperatively to investigate core chemistry concepts and connect them to real-world consumer products and careers in manufacturing that required chemistry knowledge. Findings indicated that students improved their chemistry knowledge, found greater relevance for chemistry, and intend to take more chemistry in the future. Interest in chemistry did not statistically significantly increase as a result of the intervention; however, students’ interest levels remained consistently moderate from pre-test to post. This study adds to the current body of literature in three ways. First, the intervention showcased positive outcomes with students from an urban, high-needs high school who lacked motivation and academic proficiency in science. Second, using an authentic, inquiry-based utility value intervention is a viable alternative to previous successful interventions that involved writing tasks. Finally, the study was the result of a high school teacher's advanced training in research where important evaluation skills were cultivated and advanced.

消费者化学干预对城市高危高中生的表现、效用价值和追求 STEM 意图的影响

本定量研究的主要目的是考察对城市高需求高中科学课堂进行为期三周的干预对学生（n = 51）的兴趣、实用价值、内容知识和未来意图的影响程度。学习化学。干预包括一个真实的、基于探究的化学项目，学生们合作研究核心化学概念，并将它们与需要化学知识的实际消费品和制造业联系起来。结果表明，学生们提高了他们的化学知识，发现了与化学的更大相关性，并打算在未来学习更多的化学。由于干预，对化学的兴趣在统计上没有显着增加；然而，从测试前到测试后，学生的兴趣水平始终保持中等。这项研究以三种方式增加了当前的文献体系。首先，干预展示了来自城市、高需求高中、缺乏动力和科学学术能力的学生的积极成果。其次，使用真实的、基于查询的效用价值干预是先前成功干预涉及写作任务的可行替代方案。最后，该研究是一名高中教师在研究方面的高级培训的结果，在该研究中培养和提高了重要的评估技能。缺乏动力和科学学术能力的高需求高中。其次，使用真实的、基于查询的效用价值干预是先前成功干预涉及写作任务的可行替代方案。最后，该研究是一名高中教师在研究方面的高级培训的结果，在该研究中培养和提高了重要的评估技能。缺乏动力和科学学术能力的高需求高中。其次，使用真实的、基于查询的效用价值干预是先前成功干预涉及写作任务的可行替代方案。最后，该研究是一名高中教师在研究方面的高级培训的结果，在该研究中培养和提高了重要的评估技能。
