I believe this difficulty of recognizing science as directly connected to the real world contributes to a lack of student engagement and, as a result, low academic scores. In this study, I sought to use an instructional approach called problem-based learning, in which students learn content through solving a real-world problem. The study was conducted at a suburban high school with a majority low-income, majority minority population. This set of learners has some unique challenges, including a high percentage of English-language learners and chronic absenteeism. Although my problem-based learning group did not perform better than a group of their peers who learned through a more traditional, lecture based format, there were promising results for the performance of English-language learner students and high levels of student engagement.enBiologyHigh school studentsProblem solvingAcademic achievementStudents--AttitudesThe impact of problem-based learning on academic achievement in the high school science classroomProfessional PaperCopyright 2017 by Kayla Margaret Robinson
