In fact, statistical results indicated that these variables collectively had a very small effect on critical thinking performance. Specifically, significant gains in analysis and inference skills were observed in the writing group but not the nonwriting group. Student demographics provided in Table 1 indicated an overall distribution of approximately 49% freshmen, 31% sophomores, 11% juniors, and 9% seniors. Four of the 10 sections implemented a writing component during weekly laboratory meetings (N = 158); six traditional quiz-based laboratory sections served as a nonwriting control group (N = 152). Furthermore, the use of writing and other nontraditional teaching methods did not appear to negatively affect content knowledge acquisition (Daempfle, 2002 ). Nursery Rhymes

The largest changes between initial and final essays occurred in week 1 (change of 26. This was done to help students become more proficient writers within a short period of time. In their study of undergraduate critical thinking skill in university science and math courses, Quitadamo, Brahler, and Crouch (unpublished results) showed that critical thinking skills changed within 15 wk in response to Peer Led Team Learning (a national best practice for small group learning). Course elements that were highly similar included common lecture rooms, the use of similar (in most cases identical) textbooks, and a lab facility coordinated by a single faculty member. NWP leaders study and share effective practices that enhance youth writing and learning, work collaboratively with other educators, design resources, and take on new roles in effecting positive change. An online version of the CCTST was administered in this study, which allowed the researchers to collect student demographics data including gender, ethnicity, age, and several others at the same time critical thinking skill was measured. A range of sample essays from poor to high quality was used to calibrate graduate assistant scoring and ensure consistency between assistants from different laboratory sections within the writing group. The ANCOVA test of total critical thinking performance showed that writing and nonwriting groups differed significantly, F(1, 300) = 19.
Determining the particular qualities of each instructor that contributed to student critical thinking success and further separating instructor and writing effects will require additional research. It also seems likely that writing students experienced a greater cognitive demand than nonwriting students simply because the writing act required them to hypothesize, debate, and persuade (Rivard, 1994 ; Hand and Prain, 2002 ) rather than memorize as was the case in nonwriting control courses. Specifically, business leaders are calling for graduates who possess advanced analysis and communication skills, for instructional methods that improve lifelong learning, and ultimately for an educational system that builds a nation of innovative and effective thinkers (Business-Higher Education Forum and American Council on Education, 2003 ). ArrayWriting@CSU is the home of Colorado State University's open-access learning environment, the Writing. Together, collaboration with colleagues and observed gains in critical thinking tended to create a positive feedback loop that helped to sustain writing faculty efforts.
Is it reasonable or just to expect otherwise comparable students to perform at similar levels when only some of them have the keys for success. Results from these studies would also increase the generalizability of the results from this study. A comparison of average critical thinking performance on initial essays and revised essays showed that thinking skills improvement was greater on initial essays (53%) than on final essays (33%). This design was chosen in order to compare critical thinking performance between intact groups, and because it was not feasible to randomly assign students from one course section to another within the sample. The degree to which the writing and nonwriting sections included small group collaboration in laboratory varied and all course sections differed with regards to individual instructor teaching style. Initial work focused on how the recursive and reflective nature of the writing process contributes to student learning (Applebee, 1984 ; Langer and Applebee, 1985 , 1987 ; Ackerman, 1993 ).
NWP leaders study and share effective practices that enhance youth writing and learning, work collaboratively with other educators, design resources, and take on new roles in effecting positive change. No statistically significant gains in evaluation skill were observed in either group (see Table 5 ). Ideally, students would learn the foundational tenets of critical thinking at an earlier age, and be able to refine and hone these skills as they progress through the K–20 education system. This study showed that writing affects student critical thinking skill in a nonmajors biology course, but the results have generated more questions than have been answered. Instead of individually developing course materials, writing faculty collaborated to a greater extent than nonwriting faculty on course design and assessments that required students to demonstrate their critical thinking skill.
Finally, the instructor covariable was used to account for performance differences due to individual teaching styles. As it appears that particular instructors improve student critical thinking skills more than others, students should be discerning in their choice of instructors if they want to improve their critical thinking skills. It is possible that a more diverse sample would have produced different results, or it may be that the individuals participating in this study responded particularly well to writing. Instead of individually developing course materials, writing faculty collaborated to a greater extent than nonwriting faculty on course design and assessments that required students to demonstrate their critical thinking skill. From a practical perspective, implementing writing did not take more time and effort per se; rather, it required faculty to reconceptualize how they spent their instructional time. Although not explicitly an investigation of critical thinking, results from a relatively recent study support a stronger connection between writing and reasoning ability (Daempfle, 2002 ).
By the end of the term, writing students had improved their critical thinking skill to above the 52nd percentile whereas nonwriting students decreased to below the 40th percentile. ) to help them address their thought question. 4% of variation in critical thinking skill. Although they are not always transparent to many college students, the academic and personal benefits of critical thinking are well established; students who can think critically tend to get better grades, are often better able to use reasoning in daily decisions (U. Daempfle justified his conclusions by systematically describing the methodological inconsistencies for each study.

Many wheels on a variety of topics. Writing faculty collaboratively crafted a consensus essay, or thought question, designed to elicit student critical thinking and ability to apply content knowledge. Performance on weekly thought questions was analyzed to discover specifically when and how much student critical thinking skills changed during the academic term. There were some logistical challenges with writing, like scheduling computer labs where students could draft and revise their weekly essay responses under instructor and teaching assistant supervision. Critical thinking improvement in the writing group was approximately nine times greater than the nonwriting group (see Figure 2 ). Although the authors delineate the usefulness of several composition strategies for writing in biology (Taylor and Sobota, 1998 ), it was unclear whether student data were used to support their recommendations. The covariance analysis that was conducted provided a partial means to separate out the effects of writing, prior critical thinking skill, instructor, and multiple covariables from total and component critical thinking gains. However, the author acknowledged that this work was not a research study. Specifically, students with the highest prior critical thinking skill showed the largest performance gains, whereas students with low initial skill were at a comparative disadvantage. What level of critical thinking skill do students bring to nonmajors biology courses. , 1999 ) and prior research by Quitadamo, Brahler, and Crouch (unpublished results), who showed that Peer Led Team Learning (one form of collaborative learning) helped to measurably improve undergraduate critical thinking skills.
To more fully evaluate this assumption, distributions of total and component critical thinking skill were constructed (see Figure 1 , A–D). Nursery Rhymes

Some work has been done in this area, with literature describing various approaches to writing in the biological sciences that range from linked biology and English courses, writing across the biology curriculum, and directed use of writing to improve reasoning in biology courses (Ebert-May et al. These results indicated that the ANCOVA/MANCOVA tests did not meet the homogeneity of covariance assumption. What factors influence student prior critical thinking skill. The predominant ethnicity in the sample was Caucasian (>83%), with Asian American (5%), Latino/Hispanic (3%), African American (2%), and Native American (1%) students comprising the remainder of the sample. 995, partial η2 = 0.

Goal six specifically stated that college graduates must be able to think critically (Office of Educational Research and Improvement, 1991 ). Although neither the writing nor the nonwriting group showed significant gains in evaluation skill, the writing group showed more than 3 times greater improvement than did the nonwriting group. Initial planning meetings took place just before the beginning of the academic quarter and included graduate assistant training to help them learn to consistently evaluate student writing using a modified thesis-based essay rubric (see Supplemental Appendix 2; Beers et al. In addition, the NABT exam is designed to assess high school biology performance, not college performance (Daempfle, 2002 ). At the end of the quarter, each writing group member completed a peer evaluation for all group members, including themselves (see Supplemental Appendix 3).
The concept of critical thinking includes behavioral tendencies or dispositions as well as cognitive skills (Ennis, 1985 ); these include the tendency to seek truth, to be open-minded, to be analytical, to be orderly and systematic, and to be inquisitive (Facione and American Philosophical Association, 1990 ).

Writing students also improved their evaluation skills much more than nonwriting students, although not significantly. Based on the results of this study, it could be argued that traditional lab instruction actually prevents the development of critical thinking skills, which presents a rather large problem when one considers how frequently these traditional methods are used in general education biology courses. As an instructional method, writing has long been perceived as a way to improve critical thinking. Critical thinking improvement associated with CCTST pretest score was approximately 2. In their work on integrated biology and English, Taylor and Sobota (1998) discussed several problem areas that affected both biology and English students, including anxiety and frustration associated with writing, difficulty expressing thoughts clearly and succinctly, and a tendency to have strong negative responses to writing critique.
Conversely, the lack of any significant change in analysis, inference, or evaluation skills in the nonwriting group indicated that the traditional lab instruction used in the general education biology control courses did not help students develop critical thinking skills. Teaching that supports the development of critical thinking skills has become a cornerstone of nearly every major educational objective since the Department of Education released its six goals for the nation’s schools in 1990. In the past year, the site has been visited more than 7. The pretest/posttest control group design was also used in order to minimize internal validity threats that could potentially compete with the effects of the writing treatment on student critical thinking performance. (1997) used a modified learning cycle instructional method and small group collaboration to increase reasoning ability in general education biology students. World Flags:

Simply put, students who have not been explicitly taught how to think critically may not reach the same potential as peers who have been taught these skills, not because they lack the cognitive hard-wiring to perform but because they lack the tools to build their knowledge. A comparison of initial essays indicated that students improved 53.
Additional information about learning writing:
Although critical thinking gains were influenced by writing, they did not appear to be affected by gender, ethnicity, class standing, or age. In this study, the effect of writing on critical thinking performance was investigated using the California Critical Thinking Skills Test (CCTST) at the beginning (pretest) and end (posttest) of 10 sections of general education biology at a regional comprehensive university in the Pacific Northwest. The strength of the relationship between writing and component critical thinking performance was modest but significant, accounting for more than 8% of the variance in critical thinking performance. 993, partial η2 = 0. 9%) to week 7 (average score of 81.
By focusing on instructional efforts that develop critical thinking skills, it may be possible to increase student performance while satisfying national stakeholder calls for educational improvement and increased ability to solve problems as engaged and productive citizens. National percentile rank equivalents for CCTST component raw scores indicated the writing group gained 10.

Edmentum is a leading provider of online learning programs designed to drive student achievement for. Initial results from the Delphi report were later confirmed in a national survey and replication study (Jones et al.
Levene’s test results for the ANCOVA indicated that error variances were not equal across writing and nonwriting groups, F(1,308) = 7. Prior research indicates that the writing to learn strategy is effective because students must conceptually organize and structure their thoughts as well as their awareness of thinking processes (Langer and Applebee, 1987 ; Ackerman, 1993 ; Holliday, 1994 ; Rivard, 1994 ). A quasi-experimental pretest/posttest control group design was used on a comparatively large sample of students, and considerable thought was given to controlling extraneous variables across the treatment and comparison groups. In this study, the process of writing appears to have influenced critical thinking gains. Overall, 61% of the sample was female and 39% male, with near identical gender distribution across the writing and nonwriting groups. The MANCOVA test of analysis, inference, and evaluation skills indicated that gender, ethnicity, age, class standing, academic term, and time of day did not significantly affect critical thinking performance. Class standing and age were used to indicate maturation related to time in college and chronological age, respectively.
A similar comparison of final essays showed that students improved 32. Critical thinking performance on student essays was evaluated by applying a thesis-based essay rubric (see Supplemental Appendix 2) on initial submissions and final revised essays. Factors like gender, ethnicity, and academic ability that are not directly associated with writing but may nonetheless influence its effectiveness have also not been sufficiently accounted for in previous work (Rivard, 1994 ). The nonwriting group showed a national percentile rank change of −4. This design was chosen in order to compare critical thinking performance between intact groups, and because it was not feasible to randomly assign students from one course section to another within the sample.

These future studies would further contribute to the knowledge base in this area, and also address some of its identified limitations (Ebert-May et al. Initial results from the Delphi report were later confirmed in a national survey and replication study (Jones et al. Students were given weekly thought questions before beginning laboratory to help them frame their efforts during laboratory exercises. These results confirmed that both analyses of covariance met the homogeneity of slopes assumption. Although they are not always transparent to many college students, the academic and personal benefits of critical thinking are well established; students who can think critically tend to get better grades, are often better able to use reasoning in daily decisions (U.
Similarly, Box’s test results indicated that covariance was not equal for the writing and nonwriting groups, F(6, 684,530) = 4

3% from week 1 (average score of 27. Thus, an increased focus on teaching critical thinking may directly benefit students who are engaged in science. 5 times greater than the effect of writing, and nearly 9 times greater than the effect of instructor. Although not explicitly an investigation of critical thinking, results from a relatively recent study support a stronger connection between writing and reasoning ability (Daempfle, 2002 ). 011, or the MANCOVA test, F(6, 610) = 1.
How do instructors specifically influence student gains in critical thinking. Although its effect was smaller than writing or prior critical thinking skill, the instructor variable also played a significant role in student critical thinking performance, accounting for 2. Those sections that experienced the writing treatment completed the prescriptive lab exercises in the first hour and engaged in writing during the second hour of the lab. Can their critical thinking skills be measurably improved using writing. All faculty and graduate assistants met regularly to discuss course progress, laboratory procedure, and coordinate resources. Collectively, this approach to writing and evaluation was used to 1) help students reflect on and discuss deficiencies in their collective and written work, 2) provide an opportunity for students to explicitly address deficiencies in thesis development and general writing skill, 3) provide a suitable reward for student efforts to revise their work relative to established performance benchmarks, 4) improve individual accountability within each group, and 5) help students develop more efficient and effective writing skills that collectively might lead to improved critical thinking skill.
Small group learning was also used in the nonwriting treatment groups to a greater or lesser extent depending on individual instructor preference. Using critical thinking to indicate student learning performance is particularly useful because it can be measured within and across disciplines. This design was chosen in order to compare critical thinking performance between intact groups, and because it was not feasible to randomly assign students from one course section to another within the sample. Learning to Improve: Using Writing to Increase Critical Thinking Performance in General Education Biology. 5 times greater than for instructor and nearly three times greater than for time of day. Although not explicitly an investigation of critical thinking, results from a relatively recent study support a stronger connection between writing and reasoning ability (Daempfle, 2002 ). Writing instructors were chosen on the basis of personal dissatisfaction with traditional laboratory teaching methods and willingness to try something new.
That study focused on science and math major undergraduate critical thinking performance at a major research university, and found that, in addition to Peer Led Team Learning, prior critical thinking skill significantly influenced critical thinking performance (Quitadamo, Brahler, and Crouch, unpublished results). From the literature it is clear that, although critical thinking skills are some of the most valued outcomes of a quality education, additional research investigating the effects of instructional factors on critical thinking performance is necessary (Tsui, 1998 , 2002 ). Small group learning was also used in the nonwriting treatment groups to a greater or lesser extent depending on individual instructor preference. Together, collaboration with colleagues and observed gains in critical thinking tended to create a positive feedback loop that helped to sustain writing faculty efforts. A multifaceted assessment strategy based on writing, standardized tests, and student interviews was used to quantitatively and qualitatively evaluate student content knowledge and thinking skill. Their consensus work, referred to as the Delphi report, was accomplished by a group of 46 leading theorists, teachers, and critical thinking assessment specialists from a variety of academic and business disciplines (Facione and American Philosophical Association, 1990 ).

This observation is important because it shows that students can develop critical thinking skills within a fairly short 9-wk period of time, and that writing can play a role in that process. 23 percentile in inference skill (42nd to 40th percentile), and 1. In addition to writing, prior critical thinking skill and instructor significantly affected critical thinking performance, whereas other covariables such as gender, ethnicity, and age were not significant.
