The AP Science Impact Study, which is funded by the National Science Foundation, seeks to understand the impact of Advanced Placement Biology and Chemistry classes on the high school students who take them.  It examines the effects of the updated inquiry-based curriculum on students’ confidence in scientific inquiry skills and their post-high school plans, including college type, selectivity, and major.  This study has policy implications for science curriculum and the next generation STEM workforce. 

Updates

So far this year, Mark C. Long and Dylan Conger have presented the Effects of Advanced Placement Science Courses on Students' Science Interest and Ability: Evaluation from a Randomized Control Trial paper at APPAM, SEA, SREE, and AEFP conferences in Washington D.C. 

Alec Kennedy will be presenting our findings at the American Educational Research Association (AERA) conference in San Antonio, TX.  He will be part of the session on College and Career Readiness: Evidence on Standards, Vocational Education, and Advanced Placement on Friday, April 28th, 2:15pm - 3:45pm.

Raymond McGhee Jr. will be presenting our findings at the National Science Teachers Association (NSTA) Forum on STEM in July.  More details to come.   

Science Education

AP Science & Inquiry-Based Learning

Advanced Placement courses are designed to pre­pare high school stu­dents for the rigor of col­lege course­work.  The curriculum was revised by The College Board in 2012 and 2013 to bet­ter develop stu­dents’ abil­ity to con­duct sci­en­tific inquiry, emphasizing critical thinking over factual recall.  The current AP classes are designed to give students confidence in their scientific inquiry skills, hopefully leading them on to further scientific study.

STEM & Policy Implications

Strengthening our teaching and learning of science, engineering, and quantitative reasoning is important for the workforce readiness of students, the growth of the U.S. economy, and our ability to develop innovative solutions to increasingly complex policy problems.  This study will help guide policymakers and funders to implement effective, large-scale educational policy and funding decisions and help guide educators in advising individual students and prioritizing particular classes and curriculums.

Study Design

Experimental Design

While non-experimental studies have shown large, positive effects of advanced high school courses, we seek to fill in the gaps by using an experimental design to control for other variables.  Most educational studies are observational in nature and do not involve a control and treatment group that can be compared with one another.  With a randomized experimental design, we can control for extraneous variables and make greater inferences about causation instead of just correlation. 

Hypothesis

The cen­tral hypoth­e­sis of our pro­posed research is that taking an inquiry-based AP® Biol­ogy or Chem­istry course will cause stu­dents to be more inter­ested and com­pe­tent in sci­en­tific inquiry, more likely to enroll in and com­plete col­lege, and more likely to pur­sue and per­sist in STEM majors. We fur­ther expect that stu­dents with less prior prepa­ra­tion will have more to gain from the inquiry-based AP® course and, thus, receive greater aca­d­e­mic ben­e­fits than students with more prior prepa­ra­tion. Finally, we expect larger effects in class­rooms where the cur­ricu­lum is imple­mented with a high degree of fidelity.

Project Components

The AP Science Impact study involves several different components to analyze our hypothesis, including the newly created scientific inquiry instrument, student surveys, teacher and administrator surveys and in-person interviews, classroom observations, and administrative student data.  The project is funded by the National Science Foundation, partners with researchers at George Washington University, Equal Measure, and other institutions, and is done in collaboration with The College Board.
