Abstract
CREATE (Consider, Read, Elucidate the hypotheses, Analyze and interpret the data, and Think of the next Experiment) is an innovative pedagogy for teaching science through the intensive analysis of scientific literature. Initiated at the City College of New York, a minority-serving institution, and regionally expanded in the New York/New Jersey/Pennsylvania area, this methodology has had multiple positive impacts on faculty and students in science, technology, engineering, and mathematics courses. To determine whether the CREATE strategy is effective at the community college (2-yr) level, we prepared 2-yr faculty to use CREATE methodologies and investigated CREATE implementation at community colleges in seven regions of the United States. We used outside evaluation combined with pre/postcourse assessments of students to test related hypotheses: 1) workshop-trained 2-yr faculty teach effectively with the CREATE strategy in their first attempt, and 2) 2-yr students in CREATE courses make cognitive and affective gains during their CREATE quarter or semester. Community college students demonstrated positive shifts in experimental design and critical-thinking ability concurrent with gains in attitudes/self-rated learning and maturation of epistemological beliefs about science.Entities:

OE assessment protocol and ratings of community college CREATE implementations
aIn the OE-modified Weiss protocol, “design of session” included 18 statements, “instruction of session” included 27 questions, “nature of science” included 13 statements, and “science content in session” included six statements. The OE utilized a five-point scale for rating each statement. The lowest score was designated as 1 (not at all) with scores of 2, 3, and 4 reflecting a continuum toward the highest rating of 5 (to a great extent). See the Supplemental Material for full protocol.
bCommunity colleges 1–6 (see Table 2).

Community college outcomes on cognitive measures
aExperimental Design Ability Test: Significant gains were seen in the pooled group (ES 0.29) as well as in the Bio pool (ES 0.34). Notably, nonmajors but not majors also made significant gains, with ES = 0.54.
bCritical Thinking Test. Logical statements: no significant changes are seen, either in the pooled groups or majors vs. nonmajors. Illogical statements: Pooled group shows a very small gain postcourse (ES 0.12). Majors but not nonmajors show significant change by paired t test (p < 0.05); however, ESs are comparable between majors (0.25) and nonmajors (0.24). The Bio pool shows significant gain with comparable ES (0.24). These outcomes suggest that the CC students used fewer inappropriate support statements on their postcourse surveys. Note that n differs for EDAT and CTT pools due to a variation in numbers of students who were present for both pre- and posttests, and used their codes on both tests.

Figure 2.(A) SAAB summary statements. The SAAB survey contained two summary Likert-style questions probing students’ self-rated ability to read/understand journal articles (1 = zero confidence; 2 = slight confidence; 3 = confident; 4 = quite confident; 5 = extremely confident); understand how scientific research is done (1 = no understanding; 2 = slight understanding; 3 = some understanding; 4 = understand it well; 5 = understand it very well). A third statement links the first two by asking the extent to which analyzing journal articles might have influenced students’ understanding of research (1 = no influence; 2 = very little influence; 3 = some influence; 4 = a lot of influence; 5 = major influence). Five 2-years represented, n = 73; all significant gains at p < 0.0001 (Wilcoxon signed-rank test; http://vassarstats.net/wilcoxon.html); ES = 0.72 for read/analyze journal articles; ES = 1.0 for understanding of research process; ES = 0.59 for journal articles influence my understanding of research process. (B) Community college student gains on self-rated abilities and attitudes. Each student response is represented as a dot with coordinates pre (x-axis) and post (y-axis). The reference line (y = x) indicates where responses would fall for students who answered the postcourse survey identically to the precourse survey. Responses above the line thus represent students who self-rated as having made postcourse gains; while responses below the line represent students who felt their skills diminished during the semester. The number of dots is smaller than the number of students due to many superimpositions. n = 73, pooled; 1 = I strongly disagree; 2 = I disagree; 3 = I am neutral; 4 = I agree; 5 = I strongly agree. (C) Example of outcomes in SAAB epistemological categories. Scoring as in B, except that illustrated statements were reverse scored (R). Statements above the y = x line represent more mature views that knowledge can change and ability is not innate, and conversely. Statements in the “knowledge is certain” category did not change significantly during the CREATE semesters or quarter; students’ postcourse responses are quite similar to their precourse responses. Such stability in epistemological beliefs is not unusual. Statements in the “innate ability” category changed significantly during the CREATE quarter or semester, with postcourse students significantly more likely to disagree with an “ability is innate” statement. This finding suggests a strong impact of 2-yr CREATE courses on aspects of students’ epistemological beliefs about science. See the text for discussion and Tables 7 and 8 for additional data.

aStudent responses in three of four process categories and four of the seven epistemological categories changed significantly and with small to moderate ESs during the community college CREATE courses. ESs were largest for decoding literature and sense of scientists. See Figure 2, B and C, for dot plots of selected data. The (R) indicates that statements were reverse scored; thus, an increase in scores reported reflects a decrease in student agreement, which in turn would reflect a more mature view postcourse than precourse. Thus, postcourse, community college students were less likely to agree with an ability is innate statement. No change was seen in the knowledge is certain category, in students’ sense of whether outcomes of scientific studies are known in advance, or in students’ sense of science as a collaborative activity. The latter may reflect a ceiling effect, as precourse students already agreed strongly (average precourse score 4.4) that science was collaborative.

aUsing code numbers and major status information from the SALG survey, we were able to identify 25 “majors” and 39 “nonmajors” within the SAAB data. We recalculated SAAB outcomes for 64 of the 73 students whose SAAB results are reported in Figure 2, B and C. Bold type denotes significant gains per Wilcoxon signed-rank test (Wxn; http://vassarstats.net). Notably, both cohorts made significant gains in both self-rated process skills and epistemological belief areas, with nonmajors/undecided making more gains overall than did majors. In many cases, the majors have higher pre scores than the nonmajors, but these differences were not significant (t test for unequal samples, Excel); see the text for discussion.
bBased on three of the four statements in this scale from Hoskins .
Figure 3.Pooled SALG results from six of the seven 2-yr campuses. Campuses 1–6 (Table 2); n = 85 students. Dots above the line represent students’ whose postcourse scores exceeded their precourse scores and conversely; dots on the y = x line represent students who did not change in a particular category. In each broad category, substantial self-assessed gains with large ESs were seen postcourse compared with precourse. See the text for discussion and Tables 9 and 10 for individual statements and quantitation.

aComparison of SALG outcomes for majors/future majors (n = 35) and nonmajors/undecided community college students (n = 49). Students’ status was determined from a query on the SALG survey and linked to the student’s secret code number, also included on the survey. Note that while both groups changed significantly in all categories, ESs are larger for nonmajors throughout. More majors and nonmajors are represented on this survey than on the SAAB survey, as not all students entered their code numbers and not all students were present for both the pre- and postcourse versions of each survey.
