It presents practical teaching methods for problem solving, highlights student performance patterns from 2019, and contrasts strengths in topics like population and land/water use with difficulties in global change. It also demonstrates example calculations for percent conversion and guided modeling, covering key formulas and more involved energy and unit problems.","Live Webinar:  \nThe Importance of Numerical Calculations in the AP® Environmental Science Course  \nSeptember 25, 2019  \nAndy Friedland, Environmental Studies Program, Dartmouth College  \nGoals for today:  \nPresent practical methods for introducing and explaining numerical literacy and problem solving in environmental science  \nDescribe the newly revised Third Edition of Environmental Science for the AP* Course  \nMy Involvement with AP® Environmental Science  \n1995-1998: Chaired the committee that created AP® Environmental Science and developed the first few exam offerings  \n2008-2009: Member of the College Board CDAC (Curriculum Development and Assessment Committee) which was tasked with re-evaluating AP® Environmental Science  \nPresently, no official or unofficial involvement with AP®  \nThe Importance of Problem Solving  \nA previous Chief Reader of APES stated (circa 2010) that fluency with numerical manipulation was essential to success on the APES exam  \nFind stories your students care about“Ripped from the headlines”Use data from their daily lives  \nMore recently, comments from the College Board in 2019:“Nice work! This year's AP Environmental Science students achieved the highest % of exams scoring 3+ in this subject this decade…….  \nStudents scored exceptionally well on multiple-choice questions about \"population\" and \"land and water use\" but struggled on questions about \"global change . \"  \nFree-response questions: students generally scored best on the ocean acidification question (\\#3), and scored worst on the two questions that require scientific calculations (\\#2, \\#4 )”  \nSource: Total Registration ( [https://www.totalregistration. net/AP](https://www.totalregistration. net/AP)Exam-Registration-Service/AP-Exam-Score  \nDistributions.php?year=2019 )  \nQ: What is the energy transfer in percent from Producers to Primary Consumers?  \nA: 1,000 J / 10,000 J = 0.10  \n0.1 X 100 (for percentage) =10%  \nEnvironmental Science for the AP Course, 3e.
