Critical Thinking and the Use of Nontraditional Instructional Methodologies

Effect of Concept Mapping Education on Critical Thinking Skills of Medical Students: A Quasi-experimental Study

Background

Fostering critical thinking (CT) is one of the most important missions in medical education. Concept mapping is a method used to plan and create medical care through a diagrammatic representation of patient problems and medical interventions. Concept mapping as a general method can be used to improve CT skills in medical students. The aim of this study was to explore the effect of concept mapping on CT skills of medical students.

Methods

This quasi-experimental study was conducted on 100 second-year medical students which take an anatomy course. Participants were randomly assigned into a control group (lecture-based) and an intervention group (concept mapping). CT levels of medical students were assessed using the California Critical Thinking Skills Test. Data were analyzed using independent sample t-test.

Results

Before intervention, CT scores of the intervention and control groups were 6.68 ± 2.55 and 6.64 ±2.74, respectively, and after intervention, they were 11.64 ±2.29 and 10.04 ± 3.11, respectively. Comparison of mean score differences for both groups before and after intervention demonstrated that CT scores in the experimental group significantly increased after intervention (P=0.021).

Conclusions

Medical students who were taught through concept mapping showed an increase in CT scores, compared with those in the control group. Medical students require effective CT skills in order to make sound knowledge-based assessment and treatment choices during patient care. Therefore, instructors and planners of medical education are expected to apply this educational strategy for developing CT skills in medical students.

Effects of high-fidelity simulation on the critical thinking skills of baccalaureate nursing students: A causal-comparative research study

BACKGROUND

Critical thinking has been identified as one of the standards for nursing school accreditation and a long-standing outcome of nursing education and nursing practice. High-fidelity simulation is one method currently used by nursing programs to increase critical thinking in nursing students. Despite these expectations, there is limited empirical evidence which compares the effects of simulation to other teaching strategies.

OBJECTIVES

The purpose of this study was to examine whether statistically significant differences existed in mean critical thinking skill scores within groups (pretest to posttest) and between groups (simulation versus written case studies).

DESIGN

A quantitative causal-comparative methodology with a pretest/posttest design.

SETTING

A private university in the midwestern United States which offers a four-year Bachelor of Science Nursing program.

PARTICIPANTS

Baccalaureate junior nursing students (N = 69) were recruited from a convenience sample and divided into two groups which consisted of a simulation group (n = 36) and a written case studies comparison group (n = 33).

METHODS

This research study consisted of a pretest, three weeks of being in either the simulation group or the written case studies group, and a posttest. The Health Science Reasoning Test (HSRT) was the instrument used for the pretest and posttest to measure critical thinking skills of all participants.

RESULTS

A repeated measures mixed analysis of variance (ANOVA) indicated there was no statistically significant difference in participants' mean critical thinking scores within groups (pretest to posttest) or between groups (simulation versus written case studies).

CONCLUSIONS

The use of high-fidelity simulation as a teaching strategy versus written case studies to increase critical thinking skills of nursing students was not supported.

Thinking Clinically from the Beginning: Early Introduction of the Pharmacists' Patient Care Process

Objective. To describe a student-centered teaching method used to introduce a pharmacist patient care process (PPCP) during the first year of a doctor of pharmacy (PharmD) program. Design. In the fall of 2014, a cohort of students (n=85) began an integrated pharmacotherapy (IPT) course sequence in the first semester of pharmacy school. The first course in this sequence laid the foundation for the delivery of care, focusing on the individual components of a PPCP. Faculty member used a variety of teaching methods in the course to introduce medication history taking, identification of drug-related problems, identifying components of a patient case, and learning/beginning to write subjective, objective, assessment, plan (SOAP) notes. Students' SOAP notes submissions and performance on multiple-choice examinations were evaluated to demonstrate evidence of learning. Students also completed online course evaluations. Assessment. Course-imbedded assessments were designed to measure student learning related to individual School of Pharmacy outcomes and course learning objectives. The mean individual student score on exam questions related to the PPCP topics was 83.7%±18.8%. The majority of students (86%-88%) rated their progress on achieving course learning objectives as "substantial" or "exceptional." Students also enrolled in the introductory pharmacy practice experience (IPPE) in a community setting after completing the first IPT. The students performed significantly better than a historic cohort in identifying actual and potential drug therapy problems. Conclusion. The described teaching methods, when introduced in early curricular stages, are effective in building a foundation for learning PPCP.

Efficacy of teaching methods used to develop critical thinking in nursing and midwifery undergraduate students: A systematic review of the literature

BACKGROUND

The value and importance of incorporating strategies that promote critical thinking in nursing and midwifery undergraduate programmes are well documented. However, relatively little is known about the effectiveness of teaching strategies in promoting CT. Evaluating effectiveness is important to promote 'best practise' in teaching.

OBJECTIVE

To evaluate the efficacy of teaching methods used to develop critical thinking skills in nursing and midwifery undergraduate students.

DATA SOURCES

The following six databases; CINAHL, Ovid Medline, ERIC, Informit, PsycINFO and Scopus were searched and resulted in the retrieval of 1315 papers.

REVIEW METHODS

After screening for inclusion, each paper was evaluated using the Critical Appraisal Skills Programme tool. Twenty-eight studies met the inclusion criteria and quality appraisal.

RESULTS

Twelve different teaching interventions were tested in 8 countries. Results varied, with little consistency across studies using the same type of intervention or outcome tool. Sixteen tools were used to measure the efficacy of teaching in developing critical thinking. Seventeen studies identified a significant increase in critical thinking, while nine studies found no increases, and two found unexplained decreases in CT when using a similar educational intervention.

CONCLUSIONS

Whilst this review aimed to identify effective teaching strategies that promote and develop critical thinking, flaws in methodology and outcome measures contributed to inconsistent findings. The continued use of generalised CT tools is unlikely to help identify appropriate teaching methods that will improve CT abilities of midwifery and nursing students and prepare them for practise. The review was limited to empirical studies published in English that used measures of critical thinking with midwifery and nursing students. Discipline specific strategies and tools that measure students' abilities to apply CT in practise are needed.

Effectiveness of teaching strategies on the development of critical thinking in undergraduate nursing students: a meta-analysis

Abstract OBJECTIVE To evaluate the effectiveness of teaching strategies used for development of critical thinking (CT) in undergraduate nursing students. METHOD Systematic review with meta-analysis based on the recommendations of the Joanna Briggs Institute . Searches were conducted in the following databases: PubMed, CINAHL, EMBASE, Web of Science, SCOPUS, LILACS, Cochrane CENTRAL, PsycINFO, ERIC, and a database of theses from four continents. The initial selection and evaluation of studies and assessment of methodological quality was performed by two reviewers independently. RESULTS Twelve randomized clinical trials were included in the study. In the meta-analysis of the four studies included that evaluated the strategy of problem-based learning (PBL), compared to lectures, the effectiveness of PBL was demonstrated with statistical significance (SMD = 0.21 and 95% CI = 0.01 to 0.42; p = 0.0434) for the development of CT in undergraduate nursing students, and the studies were homogeneous (chi-square = 6.10, p = 0.106). CONCLUSION The effectiveness of PBL was demonstrated in the increase of overall CT scores. Further studies need to be conducted in order to develop, implement and evaluate teaching strategies that are guided in high methodological rigor, and supported in theoretical models of teaching and learning.

Impact of a concept map teaching approach on nursing students' critical thinking skills

Nurses confront complex problems and decisions that require critical thinking in order to identify patient needs and implement best practices. An active strategy for teaching students the skills to think critically is the concept map. This study explores the development of critical thinking among nursing students in a required pathophysiology and pharmacology course during the first year of a Bachelor of Science in Nursing in response to concept mapping as an interventional strategy, using the Health Education Systems, Incorporated critical thinking test. A two-group experimental study with a pretest and posttest design was used. Participants were randomly divided into a control group (n = 42) taught by traditional didactic lecturing alone, and an intervention group (n = 41), taught by traditional didactic lecturing with concept mapping. Students in the concept mapping group performed much better on the Health Education Systems, Incorporated than students in the control group. It is recommended that deans, program directors, and nursing faculties evaluate their curricula to integrate concept map teaching strategies in courses in order to develop critical thinking abilities in their students.
