BLENDED LEARNING IN DC PUBLIC SHOOLSDANIEL K. LAUTZENHEISER AND TARYN HOCHLEITNERThe shift to TTO has also dramatically changed theresponsibilities of Hart’s math teachers. Teachers whorun a teacher-led modality are granted only 32 m<strong>in</strong>utesof <strong>in</strong>struction time, far less than they were used to<strong>in</strong> traditional classrooms. Given the fluid nature of theprogram, the modality that students use can vary day today, with teachers hav<strong>in</strong>g less of a chance to develop thesame k<strong>in</strong>d of relationship with <strong>in</strong>dividual students thatcomes from a year-long class assignment.Teachers also see big differences <strong>in</strong> their lesson plann<strong>in</strong>gpractices as they work with the daily TTO playlists.For example, they can no longer plan ahead for theentire week on a Sunday night. Orig<strong>in</strong>ally, the TTOalgorithm generated a student’s playlist for the ensu<strong>in</strong>gday by 4:00 p.m. (or even later, as John Rice recalls),limit<strong>in</strong>g the time teachers had to plan a lesson. Whenasked about this problem, MacKenzie said New Classroomsis <strong>in</strong> the process of develop<strong>in</strong>g the capacity forschedules to be generated throughout the school day asdifferent cohorts of students complete their daily exitslips—an encourag<strong>in</strong>g evolution that will likely be welcomedby teachers.Challenges with the teacher’s role presentan important dilemma for any schoolthat seeks to shift to a <strong>blended</strong> modelwith exist<strong>in</strong>g personnel.Still, such challenges make it clear why teachers whoare used to a traditional classroom may have a difficulttime transition<strong>in</strong>g to TTO. Changes to the teacher’srole present an important dilemma, not just for Hart,but for any school that seeks to shift to a <strong>blended</strong> modelwith exist<strong>in</strong>g personnel. Indeed, after the first year ofTTO, Hart Middle School experienced significantturnover among a number of its math teachers. Of theseven teachers <strong>in</strong> the math lab <strong>in</strong> the 2012–13 schoolyear, only one rema<strong>in</strong>s, and three left the school completely.“What all seven teachers from last year had <strong>in</strong>common,” Rice expla<strong>in</strong>s, “was difficulty adjust<strong>in</strong>g tothe radically different teach<strong>in</strong>g model required by TTO. . . and all found other positions either with<strong>in</strong> Hart orwith other organizations.”The high costs, coupled with some of the challengesteachers face <strong>in</strong> this different style of “classroom,” suggestthat the TTO program might not be the rightmodel for every DCPS school. And that is okay. TTOis a bold experiment for the district—one they know<strong>in</strong>glytook on, and one that has much promise <strong>in</strong> astruggl<strong>in</strong>g school. Part of the advantage of the DCPSstrategy is that it allows the district to experiment withmultiple <strong>blended</strong> models and see which ones work and<strong>in</strong> which contexts they work. The district seems will<strong>in</strong>gto wait and see how that plays out at Hart.Anacostia High School: Discovery Education Techbooks.When we arrived at Anacostia High School,only 5 of the 30 or so desks were occupied. Threemore students trickled <strong>in</strong> dur<strong>in</strong>g our visit, but the paltrynumber is reflective of a school grappl<strong>in</strong>g with highrates of truancy. After a few m<strong>in</strong>utes of overview, theteacher <strong>in</strong>structed the students to take out class laptopsand log <strong>in</strong>to their “techbooks.” The techbooks are runvia a DCPS partnership with Discovery Education, arapidly grow<strong>in</strong>g arm of the media and communicationsgiant based <strong>in</strong> nearby Silver Spr<strong>in</strong>g, Maryland. As wenoted earlier, the techbooks are an entirely onl<strong>in</strong>e portalwith a host of multimedia and other features.In theory, this model is filled with possibilities. Notonly does an onl<strong>in</strong>e platform allow for a wide variety ofcontent, but the assessments can be taken quickly andresults viewed immediately. If the students log <strong>in</strong> us<strong>in</strong>gunique IDs, the teacher would be able to track eachstudent’s progress. The techbooks also allow studentsto work at their own pace, with the teacher free to walkaround the room and give more tailored <strong>in</strong>struction.But such capabilities are beneficial only when usedto their full advantage—a responsibility that fell, <strong>in</strong>this case, on the classroom teacher. Students logged<strong>in</strong> not with unique IDs but with generic ones, negat<strong>in</strong>gthe ability of the techbook to track their <strong>in</strong>dividualperformance. At the same time, the teacher asked studentsto answer questions on a worksheet rather thantak<strong>in</strong>g advantage of the capability to do so onl<strong>in</strong>e. Inthis classroom, <strong>in</strong> other words, the blend of teacher-ledand onl<strong>in</strong>e <strong>in</strong>struction did not lead to a new <strong>learn<strong>in</strong>g</strong>experience. Digital content had simply replaced thenondigital, rather than be<strong>in</strong>g a catalyst for restructur<strong>in</strong>gthe teacher’s lesson, free<strong>in</strong>g up her time to focus11
