ABSTRACTCREATE (consider, read, elucidate hypotheses, analyze and interpret the data, and think of the next
experiment) is a new method for teaching science and the nature of science through primary literature.CREATE uses a unique combination of novel pedagogical tools to guide undergraduates through analysis ofjournal articles, highlighting the evolution of scientific ideas by focusing on a module of four articles fromthe same laboratory. Students become fluent in the universal language of data analysis as they decipher thefigures, interpret the findings, and propose and defend further experiments to test their own hypothesesabout the system under study. At the end of the course students gain insight into the individual experiencesof article authors by reading authors’ responses to an e-mail questionnaire generated by CREATE students.Assessment data indicate that CREATE students gain in ability to read and critically analyze scientific data, aswell as in their understanding of, and interest in, research and researchers. The CREATE approachdemystifies the process of reading a scientific article and at the same time humanizes scientists. The positiveresponse of students to this method suggests that it could make a significant contribution to retainingundergraduates as science majors.
DESPITE the stunning success of research sciencein the last half of the 20th century, there is a gen-
eral consensus that the teaching of science to collegestudents has not made parallel gains (Chickering andGamson 1987; Felder 1987; American Associationfor the Advancement of Science 1989; Seymour andHewett 1997; Glenn Commission 2000; McCray et al.2003; National Research Council 2003; Handlesmanet al. 2004; Alberts 2005; Cech and Kennedy 2005).Indeed, the vast increase in scientific knowledge haspotentially contributed to this problem, because instruc-tors feel compelled to teach their students an ever-growing body of facts, and students spend more timehoning their memorization skills than they do learninghow to understand and evaluate scientific data. The
sense of discovery felt by the scientists involved in gen-erating this new information is unfortunately rarely com-municated to undergraduates. Textbooks, for example,typically present the growth of scientific knowledge as agradual increase of information over time, ignoring theblind alleys, digressions, and unexpected findings thatin fact characterize research science. Although labora-tory courses are often proposed as a complement tolecture classes that rely on textbooks, students in labclasses too often test hypotheses developed by others,perform experiments for which the results are known,and fail to become intellectually invested in their re-sults. Many undergraduate science majors do not havethe opportunity to carry out individual laboratory re-search projects; even for those that do, the short-termnature of most such projects makes it difficult for stu-dents to visualize how their work fits into the overallscientific progress of the laboratory. As a consequence,many undergraduates have little sense of how scientific

knowledge is generated, how research projects progressover time, or of how scientists think about and actuallydo research. These factors often combine to inducedisappointed students to drop out of science majors(Seymour and Hewett 1997; Alberts 2005; Cech andKennedy 2005), a problem that is exacerbated for minor-ity students, who remain underrepresented at all levelsof academic science (National Science Foundation2002; American Council on Education 2003; Bok2003, Atwell 2004; total enrollment by gender/race/ethnicity is at http://www.aamc.org/data/facts/2003/2003school.html).
As one approach to addressing these problems, wehave developed CREATE (consider, read, elucidate hy-potheses, analyze and interpret data, and think of thenext experiment), a teaching method that involves stu-dents in reading and analyzing the primary scientificliterature while simultaneously exposing them to theintellectual excitement and challenges experienced bythe scientists who carried out the work under discussion.In contrast to other approaches that use single or par-tial journal articles in the undergraduate classroom( Janick-Buckner 1997; Herman 1999; Muench 2000;Chowe and Drennan 2001; Klemm 2002; Herreid2004), CREATE focuses on a sequence of articles thatreports a single line of research from one laboratory as itdeveloped over a period of years. In addition to pro-moting the development of skills that students need tounderstand and analyze scientific information, theCREATE approach introduces students to issues re-garding the nature of science (Lederman 1992;Schwartz et al. 2004) and to the creative roles playedby individuals in scientific research. CREATE is notmeant to substitute for standard lecture classes andhands-on research projects, but rather to supplementand complement such classes. Consistent with the rec-ommendations of recent reform documents (AmericanAssociation for the Advancement of Science 1989;Bransford et al. 1999; Glenn Commmission 2000;National Research Council 1999, 2000, 2003), CREATEinvolves in-depth study of a single line of scientific re-search, which takes advantage of the narrative nature ofscience (Muench 2000; Kitchen et al. 2003). A CREATEmodule consists of four articles, published in sequencefrom the same lab, that are read and analyzed sequen-tially, providing insight into the evolution of ideas as aproject develops over time.
As outlined below, CREATE employs a unique combi-nation of pedagogical tools and active classroom ap-proaches that facilitate learning (Bransford et al. 1999;Siebert and McIntosh 2001; Chin et al. 2002; Zoharand Nemet 2002; Osborne et al. 2004). We had twooverall goals. The first was to develop each student’sability to think like a scientist in terms of designing ex-periments, analyzing and interpreting data, and crit-ically evaluating results as well as proposed follow-upexperiments. Our second goal was to increase the stu-
dents’ interest in science and scientific research byproviding them with insights into the experiences, bothintellectual and personal, of working scientists. Wetested the ability of CREATE to meet these goals in anelective course for juniors and seniors that requiredGenetics and Cell Biology as prerequisites. The 3-creditCREATE class met twice weekly for 75 min/class with asingle instructor (S. G. Hoskins), and the class sizeranged from 12 to 25 students in the three separateclasses (51 students overall) that are discussed in this re-port. We focused on a module of four articles from thelaboratory of Christine Holt (Cambridge, UK) (Nakagawaet al. 2000; Mann et al. 2002, 2003; Williams et al. 2003)that analyze the role of ephrin/eph-mediated signaltransduction in axon guidance during optic nervedevelopment. Our assessments indicate improvementsboth in the ability of CREATE students to thinkscientifically and in their confidence in their abilities.Importantly, CREATE students also developed a newappreciation for science and for scientists as individuals.
THE CREATE METHOD
In our previous experience, when students were as-signed to read research articles, they often read only theabstract, introduction, and discussion, merely glanced atthe figures and tables, and accepted the authors’ con-clusions without developing a thorough understandingof the experimental results on which they were based. Toavoid this problem, we do not initially provide CREATEstudents with the articles’ titles, abstracts, discussion/conclusion sections, or the authors’ names. Using thespecific exercises outlined below, we challenge the stu-dents to understand the methods, explain the experi-mental designs, and interpret the data as if they hadmade these findings themselves. Class discussion focuseson figure-by-figure data analysis and interpretation, withthe professor acting as ‘‘lab head’’ and discussion leader,guiding students through evaluation of experiments andin synthesis and application of scientific concepts—higher-level cognitive activities known to facilitate un-derstanding (Bloom et al. 1956). Mini-lectures of 10–15min are occasionally used to review essential backgroundmaterial, but most class time is spent in whole-class orsmall-group discussion. After analyzing each article, thestudents generate their own proposals for what the nextexperiment would be if they were carrying out the re-search themselves. They then discuss and debate theirideas with other students in an exercise meant to modelthe peer review that real science undergoes. As theCREATE process repeats with each module article, stu-dents experience how an actual research project devel-ops over time. To enhance the students’ understandingof the personal experience of scientists carrying outresearch, students communicate with some of the articleauthors by e-mail, in which they pose their own questions
1382 S. G. Hoskins, L. M. Stevens and R. H. Nehm
about researchers’ motivations and experiences. Sequen-tial steps of the CREATE process are summarized below:
Consider: We explain to the students that, as theyread each article, our goal is for them to work throughthe data as if they had generated it themselves. To fa-cilitate this, they are given each section (Introduction, Re-sults and Methods, Discussion) sequentially and they arenot provided with the title and abstract of the article norwith the names of the authors. Although some studentsmay try to circumvent this process by using the Internetto obtain the complete article prematurely, we did notfind this to be a problem in our CREATE classes. Even ifstudents do ‘‘look ahead,’’ it does not significantly in-terfere with their learning experience because most ofthe CREATE activities require the students to think forthemselves.
The students are introduced to the principles ofconcept mapping (Good et al. 1990; Novak 1990, 2003;Allen and Tanner 2003). They are then assigned toread the Introduction section of the first article andto construct a concept map of it by defining key termsand creating appropriate diagrammatic linkages be-tween them. Such maps highlight the range of issuesthat the article addresses and alert students to conceptsthat they need to review in preparation for reading andanalyzing the article. This exercise empowers the stu-dents to take charge of their own learning (Novak andGowin 1984; Brooks and Brooks 1993).
Read: Students read the Methods and Results sec-tions of the article. Then they are instructed to gothrough the Results section figure by figure and, usingthe information in the Methods section, ‘‘work back-wards’’ from the data presented in each figure (or table)to determine how the results were obtained, that is,what experiment was performed. Students (1) diagrameach experiment in a cartoon format that illustratesthe methods used, (2) annotate the figures by addingclarifying labels, and (3) write their own descriptivetitles for each cartoon and each figure. We emphasizethat the cartoons are meant to depict what was physicallydone in each experiment (see Figure 1 for an exampleof a CREATE student’s cartoon), not to show what theresults were or to restate what the authors said about theexperiment. We require the students to draw a sketchfor this step, rather than a flow chart. We find thatcreating a visual representation of what was done ineach experiment is critical for the students’ ability tointerpret the resulting data. In the annotation step, thestudents use the information from the figure legend toinstructively label each panel in the figure. They notewhich panels serve as controls and which are experi-mental and also categorize the type of experimentdepicted, e.g., ‘‘dose-response histogram.’’ To carry outthis step, students must look closely at the figures andtheir legends to determine exactly what is representedin each panel. Finally, writing their own titles for thefigures as well as their cartoons gives the students a sense
of ownership of the material and can help them to distillthe essential information. For example, one studentrewrote ‘‘Ephrin-B overexpression at the chiasm in-duces precocious ipsilateral projections in the earlytadpole’’ as ‘‘Early Ephrin-B drives axons ipsilaterally.’’
Each of these activities promotes the developmentof conceptual linkages between what was actually donein each experiment and the data that were obtained.These methods encourage visualization and abstractionas well as integrative and synthetic thinking, all of whichfacilitate learning (Bloom et al. 1956; Kozma andRussell 1997; Foertsch 2000, Zull 2002; Yuretich2004). These steps—the cartooning, annotation, andretitling—are done by students as homework in prepa-ration for class. Thus, students arrive in class familiarwith the article and ready to participate actively in classdiscussion.
Elucidate the hypotheses: Research articles typicallyinvolve numerous individual experiments, each of whichplays a role in the final conclusions. Introductions toarticles, however, tend to emphasize one major finding,and the Materials and Methods sections often describethe methods without linking them to individual figuresor tables. The students triangulate between their car-toons, annotated figures, and rewritten figure/tabletitles to dissect the ‘‘anatomy’’ of the study by identifyingeach individual experiment and defining the specifichypothesis that it tested or the question that it addressed.The student-generated hypotheses or questions arewritten above the figure or table to which they apply.
Figure 1.—Sample student cartoon. To link the informa-tion given in the Methods sections with the data representedin figures and tables of the Results, students make sketches toillustrate the experiments that were performed. The studentcartoon above illustrates an experiment in which mouse Lcells were transfected with frog ephrinB2 and then frog reti-nal explants were challenged to extend axons on membranecarpets made from the L cells. Creating these visual represen-tations facilitates understanding of the hands-on lab work thatled to the results reported.

Analyze and interpret the data: Students analyze eachfigure using CREATE analysis templates (supplementalFigure S1 at http://www.genetics.org/supplemental/),which build on the work done in the previous stepsand guide them in determining which panels in afigure (or numbers in a table) should be compareddirectly. As they fill in the templates, students comparethe control and experimental panels that they identi-fied during figure annotation, relate the results to thehypothesis or question that the experiment addresses,and begin to draw conclusions. Students also explicitlyrelate the findings to the hypotheses previously eluci-dated, judge how convincing they find the data to be,and note any questions that they would like to ask theauthors. Templates filled out as homework preparestudents for active discussion of the outcomes of ex-periments. Templates are always used for article 1 ofthe module. Some students continue to use them forsubsequent articles while others are able to generatetheir own analyses after their initial experience withthe templates.
Class discussion of the articles focuses on data anal-ysis, and the instructor runs the discussion much like alab meeting. Some analysis is done in small groups, withstudents charged to work together and then to reporttheir conclusions back to the class. When all of the fig-ures have been analyzed and thoroughly discussed inclass, students record their overall interpretations andconclusions as a list of bulleted points—points that theythink would be worth including in a Discussion section.Only after completing their own lists are students pro-vided with the actual Discussion section of the article.After reading it, they make a similar list of points basedon the authors’ conclusions. Comparing the two listshighlights the role of interpretation in science, show-ing that data may be interpreted from several differ-ent or even opposing viewpoints (Germann and Aram1996). Finally, students make a summary concept map,this time using the articles’ figures and tables as centralconcepts and creating linkages between them that indi-cate the logical flow of ideas in the article. After theintense and detailed analysis of individual experiments,this is an opportunity for the students to step back andweave the individual parts of the article into a ‘‘bigpicture.’’
Think of the next experiment: Each student imag-ines that he or she is an author of the article justanalyzed and asks: What experiments should be donenext? The students diagram two of their proposedexperiments in cartoons that are discussed in class. Tomodel the scientific peer-review process, the class collab-oratively devises criteria for judging proposals and thendivides into several three- or four-person ‘‘grant panels,’’each of which selects one of the student experiments to‘‘fund.’’ Often, different groups choose different ‘‘best’’experiments. Such an outcome contrasts with somestudents’ preexisting views of scientific research as a
linear path with one obvious step after another. Grantpanel discussions help students hone data interpreta-tion and verbal logic skills (Vanzee and Minstrell1997; Marbach-Ad and Sokolove 2000; Zohar andNemet 2002) and foster an understanding of howscience works by modeling the discussions and debatesthat are characteristic of research laboratories (Steitz2003) and actual grant panels.
Final steps and reiteration of the CREATE process:After the CREATE methods are applied to the firstarticle, the process is repeated with each additionalmodule article, although in these cases there is theadded excitement of discovering whether the experi-ments reported in the subsequent articles match any ofthe students’ proposed experiments. For students whoindependently had the same idea as the authors, theexperience reinforces the idea that they are learning tothink like scientists. For students who have different‘‘next experiments,’’ the experience underscores theidea that real projects can move in many differentdirections. This realization contrasts with some stu-dents’ previously held beliefs that science is very pre-dictable and that scientists always know what theirresults will be (Table 1 and supplemental Table S1 athttp://www.genetics.org/supplemental/). Analysis ofthe subsequent articles generally proceeds more rap-idly because the students are now familiar with theexperimental system as well as with the CREATE tools.
Interviews with scientist–authors: At the conclusionof the module, our first class of CREATE students pre-pared a survey of 12 questions (supplemental TableS2 at http://www.genetics.org/supplemental/) that wase-mailed to each author of the four articles, a group thatincluded technicians, graduate students, postdoctoralfellows, and principal investigators. One author visitedthe class and was interviewed directly in a session thatwas videotaped. Subsequent CREATE student cohortsread the e-mail interviews and viewed the videotapegenerated by the first class; thus, authors were contactedonly once. CREATE students’ questions ranged fromscientific (‘‘How did you choose your research area?’’)and ethical concerns (‘‘Have you ever encountered anyethical issues and how were they resolved?’’) to morepersonal issues (‘‘Did you ever wake up and just want togive up? How did you deal with it?’’). The range ofresponses from 10 different authors (50% responserate) to the same questions highlighted for students thatscientists are individuals with different motivations andgoals. Especially important for our students was the re-alization that their previous stereotypes of scientists as‘‘antisocial’’ and as ‘‘geniuses’’ were inaccurate (Table 1and supplemental Table S1 at http://www.genetics.org/supplemental/), which evoked comments such as: ‘‘Irealized !for the first time" that scientists are people likeme. . . . if I wanted to, if I worked at it . . . I could becomea scientist’’ (supplemental Table S1 at http://www.genetics.org/supplemental/).

Assessment: Many studies that describe methods forengaging undergraduate students with the primary sci-entific literature have been published (see, for example,Janick-Buckner 1997; Herman 1999; Muench 2000;Chowe and Drennan 2001; Mangurian et al. 2001;Klemm 2002; Herreid 2004). We did not directly com-pare the CREATE approach with these other methodsbecause we did not design CREATE solely as a methodfor reading the primary literature. Instead, the CREATEapproach uses a linked sequence of articles as a portalinto the research laboratory such that the studentsexperience many of the cognitive activities that scien-tists use in their daily work. CREATE students also hadthe opportunity to learn about the personal experiencesof the scientists involved in the work. Our goal was toachieve a synergy between the intellectual and personalaspects of research science that would enhance stu-dents’ interest in science as well as their abilities to readand understand scientific literature. For these reasons,we chose to use pre- and post-course testing, an estab-lished approach in science education, to determinewhether the students made gains in these specific areas(Edwards and Fraser 1983; McMillan 1987; Ruiz-Primo and Shavelson 1996; Stoddart et al. 2000;Bissell and Lemons 2006; Bok 2006).
To determine whether there were improvements inthe students’ ability to critically read and interpret data,we administered critical thinking tests (CTTs; adaptedfrom http://www.flaguide.org/) pre- and post-course.CTT questions required the use of general data analysisskills and were not specific to the CREATE module. Todetermine whether the CREATE approach facilitatedthe ability of students to understand and integrateconcepts related to the module content, we carriedout pre- and post-course assessments in which studentsconstructed concept maps based on seed terms (Novak2003). (Note that these assessment maps were distinctfrom previously described concept maps used as learn-ing tools in the CREATE classroom.) Finally, to explorestudents’ understanding of the nature of science andtheir attitudes toward science and scientists, we usedoral interviews (Glaser and Strauss 1967; Novak1998; Ary et al. 2002) and an online, anonymous Self-Assessed Learning Gains survey (http://www.wcer.wisc.edu/salgains/instructor/). The latter two assessmentsalso provided information on the students’ own percep-tions of how their critical thinking and data analysisskills had changed and gave us feedback on students’reactions to the course format.
CREATE, in all three implementations, was demon-strated to improve students’ critical thinking skills(Figure 2) and their ability to read/analyze scientificliterature and understand complex content (Figure 2and supplemental Figures S2 and S3 at http://www.genetics.org/supplemental/). Students taught using theCREATE method self-reported increased confidence intheir reading and analysis abilities, as well as enhanced
skills that transferred from the CREATE class to otherscience classes (supplemental Figure S4 at http://www.genetics.org/supplemental/). They also exhibitedimproved understanding of the nature of science,increased interest in science participation, enhancedpersonal engagement with science, and more positiveviews of science and scientists (Table 1; supplementalFigure S4 and supplemental Table S1 at http://www.genetics.org/supplemental/). Thus, CREATE studentsexperienced gains in both their academic skills andtheir perception of the scientific enterprise.
Figure 2.—Summary of results on CTT. Students whotook CREATE classes demonstrated gains in their ability tocritically analyze data and draw logical conclusions. CTTs re-quiring data interpretation were administered pre- and post-course. The CTT was a 30-min closed-book activity, designedon the basis of the Field-tested Learning Assessment Guide(http://www.flaguide.org/), in which students read and re-sponded to six ‘‘story problems’’ requiring them to interpretdata presented in charts or tables and explain why they did ordid not agree with the conclusions stated in the problem. Thistest was not based on material covered in the CREATE mod-ules. Horizontal bars with asterisks indicate questions onwhich significant increases in numbers of logical justifications(statements) or decreases in numbers of illogical justificationswere seen post-course, compared to pre-course, in written re-sponses to CTT questions (***P , 0.001; **P , 0.02; *P ,0.05; paired t-test). These data suggest that students’ criticalthinking and data analysis abilities improved during theCREATE semester. For each question, we included only datafor students who answered the same question in both pre- andpost-tests; thus, the N is smaller for questions 4, 5, and 6. Errorbars indicate standard error. Questions 1–3, N # 48; question4, N # 42; question 5, N # 34; question 6, N # 24. Additionalinformation regarding the CTT appears in the supplementaldata at http://www.genetics.org/supplemental/.

CONCLUSIONS
To our knowledge, CREATE is the only multiplyassessed educational method shown to increase bothunderstanding of and interest in scientific researchamong undergraduate students. In this regard it is alsonotable that 64% of our CREATE students were mem-bers of minority groups that are traditionally underrep-resented among students progressing on to careers inscience. We anticipate that the CREATE method willbenefit students from a variety of backgrounds, how-ever. Our data suggest that the CREATE approach couldsignificantly alleviate the well-documented disengage-ment of many college students from science (Seymourand Hewett 1997; National Science Foundation2002; Alberts 2005; Cech and Kennedy 2005). It is alsoimportant to note that the CREATE approach does notrequire any significant financial expenditure and there-fore will be accessible to instructors at many differenttypes of institutions.
We believe that the CREATE curriculum, which en-courages students to think of themselves as scientists, willcomplement and enhance students’ experience of tradi-tional lecture-based science teaching and inquiry labclasses. Although CREATE was initially developed for usein an upper division elective course with relatively few stu-dents, we believe that elements of the CREATE methodcan be effectively adapted for use in lower division andlarger science classes. The approach is adaptable tocontent in any area of science, and articles can be chosento be accessible to students at a variety of levels. Earlierexposure to CREATE analytical approaches may help stu-dents to develop critical analysis skills early in their collegecareers so that they can benefit from them throughouttheir college coursework (Braxton et al. 2000). Corre-spondingly, the earlier that students develop an appre-ciation for the creative nature of scientific investigationand, in particular, recognize that they, too, could makean important contribution to science, the less likely it isthat they will drop out of science majors.
In contrast to K–12 teachers, most instructors at thecollege level have not had formal training in how toteach effectively. Many faculty members in the sciencesobtain academic positions and promotions on the basisof their research accomplishments. In this respect, webelieve that the CREATE approach can benefit instruc-tors as well as students because, rather than requiringinstructors to learn a completely new teaching method,it encourages faculty members to use skills that manyemploy in their laboratories every day. The CREATEclass is very similar to a lab meeting in which methodsare described, results reported and analyzed, interpre-tations discussed, and future directions debated. Inshort, by using primary literature as a portal into theactivities of working scientists, and by guiding classdiscussions rather than lecturing, instructors can createa virtual laboratory in which every student is a scientist.
We thank David Eastzer, Shubha Govind, and David Stein for theirvaluable discussions and advice during the development and imple-mentation of this project. We thank Ruth Ellen Proudfoot for adviceon statistical analyses, Christina Nadar and Arturo de Lozanne for helpwith graphics, and two anonymous reviewers for insightful commentson a previous version of the article. We also are very grateful to CarolMason for her participation in a group interview, to Christine Holt forher encouragement of the project, and to all of the article authors whoresponded by e-mail to our students. Finally, we thank all of the CityCollege of New York students who participated in the CREATE classes.This material is based upon work supported by the National ScienceFoundation (NSF) under grant no. 0311117 to S.G.H. and L.M.S. (Co-Principal Investigators). We thank the NSF for support and the NSFCourse, Curriculum and Laboratory Improvement program officersfor helpful discussions during the development and implementationof the CREATE project.
