Project description:IntroductionSince medical students matriculate with a diversity of backgrounds, there can exist a disparity in student ability to critically appraise health science literature. To address this, we developed a critical appraisal exercise and integrated it into the first-year problem-based learning (PBL) curriculum at Case Western Reserve University School of Medicine.MethodsFor 8 weeks, first-year medical students read a weekly preselected health science literature article relating to the content of their PBL curriculum and completed a critical appraisal worksheet consisting of questions regarding study design and result interpretation. Students discussed the article and worksheet within PBL small groups. Faculty facilitators were given the critical appraisal worksheet answer key, which students later gained access to after the discussion. To measure changes in critical appraisal skills, a voluntary questionnaire based on the Berlin questionnaire, a validated tool for measuring knowledge and skills in evidence-based medicine, was administered before and after the 8-week intervention.ResultsUsing paired Student t tests, we found that the students who completed both questionnaires (N = 60) showed an average improvement of 4% (p = .03). Students who scored at or below the 50th percentile on the preintervention questionnaire showed an average improvement of 12% (p = .002).DiscussionThese critical appraisal worksheets are easily adaptable to an existing PBL curriculum and are an effective tool for improving and teaching critical appraisal skills in those students who will benefit most.

Project description:Background The complex health system and challenging patient care environment require experienced nurses, especially those with high cognitive skills such as problem-solving, decision- making and critical thinking. Therefore, this study investigated the impact of social problem-solving training on nursing students’ critical thinking and decision-making. Methods This study was quasi-experimental research and pre-test and post-test design and performed on 40 undergraduate/four-year students of nursing in Borujen Nursing School/Iran that was randomly divided into 2 groups; experimental (n?=?20) and control (n?=?20). Then, a social problem-solving course was held for the experimental group. A demographic questionnaire, social problem-solving inventory-revised, California critical thinking test, and decision-making questionnaire was used to collect the information. The reliability and validity of all of them were confirmed. Data analysis was performed using SPSS software and independent sampled T-test, paired T-test, square chi, and Pearson correlation coefficient. Results The finding indicated that the social problem-solving course positively affected the student’ social problem-solving and decision-making and critical thinking skills after the instructional course in the experimental group (P?<?0.05), but this result was not observed in the control group (P?>?0.05). Conclusions The results showed that structured social problem-solving training could improve cognitive problem-solving, critical thinking, and decision-making skills. Considering this result, nursing education should be presented using new strategies and creative and different ways from traditional education methods. Cognitive skills training should be integrated in the nursing curriculum. Therefore, training cognitive skills such as problem- solving to nursing students is recommended.

Project description:Although development of critical thinking skills has emerged as an important issue in undergraduate education, implementation of pedagogies targeting these skills across different science, technology, engineering, and mathematics disciplines has proved challenging. Our goal was to assess the impact of targeted interventions in 1) an introductory cell and molecular biology course, 2) an intermediate-level evolutionary ecology course, and 3) an upper-level biochemistry course. Each instructor used Web-based videos to flip some aspect of the course in order to implement active-learning exercises during class meetings. Activities included process-oriented guided-inquiry learning, model building, case studies, clicker-based think-pair-share strategies, and targeted critical thinking exercises. The proportion of time spent in active-learning activities relative to lecture varied among the courses, with increased active learning in intermediate/upper-level courses. Critical thinking was assessed via a pre/posttest design using the Critical Thinking Assessment Test. Students also assessed their own learning through a self-reported survey. Students in flipped courses exhibited gains in critical thinking, with the largest objective gains in intermediate and upper-level courses. Results from this study suggest that implementing active-learning strategies in the flipped classroom may benefit critical thinking and provide initial evidence suggesting that underrepresented and first-year students may experience a greater benefit.

Project description:Critical thinking, the capacity to be deliberate about thinking, is increasingly the focus of undergraduate medical education, but is not commonly addressed in graduate medical education. Without critical thinking, physicians, and particularly residents, are prone to cognitive errors, which can lead to diagnostic errors, especially in a high-stakes environment such as the intensive care unit. Although challenging, critical thinking skills can be taught. At this time, there is a paucity of data to support an educational gold standard for teaching critical thinking, but we believe that five strategies, routed in cognitive theory and our personal teaching experiences, provide an effective framework to teach critical thinking in the intensive care unit. The five strategies are: make the thinking process explicit by helping learners understand that the brain uses two cognitive processes: type 1, an intuitive pattern-recognizing process, and type 2, an analytic process; discuss cognitive biases, such as premature closure, and teach residents to minimize biases by expressing uncertainty and keeping differentials broad; model and teach inductive reasoning by utilizing concept and mechanism maps and explicitly teach how this reasoning differs from the more commonly used hypothetico-deductive reasoning; use questions to stimulate critical thinking: "how" or "why" questions can be used to coach trainees and to uncover their thought processes; and assess and provide feedback on learner's critical thinking. We believe these five strategies provide practical approaches for teaching critical thinking in the intensive care unit.

Project description:National stakeholders are becoming increasingly concerned about the inability of college graduates to think critically. Research shows that, while both faculty and students deem critical thinking essential, only a small fraction of graduates can demonstrate the thinking skills necessary for academic and professional success. Many faculty are considering nontraditional teaching methods that incorporate undergraduate research because they more closely align with the process of doing investigative science. This study compared a research-focused teaching method called community-based inquiry (CBI) with traditional lecture/laboratory in general education biology to discover which method would elicit greater gains in critical thinking. Results showed significant critical-thinking gains in the CBI group but decreases in a traditional group and a mixed CBI/traditional group. Prior critical-thinking skill, instructor, and ethnicity also significantly influenced critical-thinking gains, with nearly all ethnicities in the CBI group outperforming peers in both the mixed and traditional groups. Females, who showed decreased critical thinking in traditional courses relative to males, outperformed their male counterparts in CBI courses. Through the results of this study, it is hoped that faculty who value both research and critical thinking will consider using the CBI method.

Project description:This study evaluated hypothesized effects of the Peer-Led Team Learning (PLTL) instructional model on undergraduate peer leaders' critical thinking skills. This investigation also explored peer leaders' perceptions of their critical thinking skills. A quasi-experimental pre-test/post-test with control group design was used to determine critical thinking gains in PLTL/non-PLTL groups. Critical thinking was assessed using the California Critical Thinking Skills Test (CCTST) among participants who had previously completed and been successful in a mixed-majors introductory biology course at a large, private research university in the American Northeast. Qualitative data from open-ended questionnaires confirmed that factors thought to improve critical thinking skills such as interaction with peers, problem solving, and discussion were perceived by participants to have an impact on critical thinking gains. However, no significant quantitative differences in peer leaders' critical thinking skills were found between pre- and post-experience CCTST measurements or between experimental and control groups.

Project description:Critical thinking (CT) is widely recognized as an important skill and attitude in this modern world, but few apps (web-based or installed on devices) have been developed to effectively train it. There is also little research on what kind of content to put into such apps and in what order, if the content is a series of reasoning questions that are intended as CT exercises. Therefore, this research project, consisting of two studies, tries to demonstrate how exercise questions can be presented to learners to sustain their motivation to work on multiple-choice CT questions. In Study 1, question banks were drawn from popular workbooks for CT and verbal reasoning. The questions were ranked in terms of difficulty based on the participation of university students (N = 73). In Study 2, the questions were loaded onto two types of web-based apps: (1) one that sequentially gives multiple-choice questions with immediate feedback and (2) one with minimum gamification of group/individual competition. The experiment to examine the effect of the gamification was conducted (N = 114). Both groups with and without gamification showed improvements in the scores of the pre-/post-tests using comparable questions, but there was no clear effect of gamification. These findings show that an effective CT app can be developed using existing question banks but that the effect of gamification needs further research.

Project description:MotivationIn the field of pharmacochemistry, it is a time-consuming and expensive process for the new drug development. The existing drug design methods face a significant challenge in terms of generation efficiency and quality.ResultsIn this paper, we proposed a novel molecular generation strategy and optimization based on A2C reinforcement learning. In molecular generation strategy, we adopted transformer-DNN to retain the scaffolds advantages, while accounting for the generated molecules' similarity and internal diversity by dynamic parameter adjustment, further improving the overall quality of molecule generation. In molecular optimization, we introduced heterogeneous parallel supercomputing for large-scale molecular docking based on message passing interface communication technology to rapidly obtain bioactive information, thereby enhancing the efficiency of drug design. Experiments show that our model can generate high-quality molecules with multi-objective properties at a high generation efficiency, with effectiveness and novelty close to 100%. Moreover, we used our method to assist shandong university school of pharmacy to find several candidate drugs molecules of anti-PEDV.Availability and implementationThe datasets involved in this method and the source code are freely available to academic users at https://github.com/wq-sunshine/MomdTDSRL.git.

Project description:The learning rate is a key parameter in reinforcement learning that determines the extent to which novel information (outcome) is incorporated in guiding subsequent actions. Numerous studies have reported that the magnitude of the learning rate in human reinforcement learning is biased depending on the sign of the reward prediction error. However, this asymmetry can be observed as a statistical bias if the fitted model ignores the choice autocorrelation (perseverance), which is independent of the outcomes. Therefore, to investigate the genuine process underlying human choice behavior using empirical data, one should dissociate asymmetry in learning and perseverance from choice behavior. The present study addresses this issue by using a Hybrid model incorporating asymmetric learning rates and perseverance. First, by conducting simulations, we demonstrate that the Hybrid model can identify the true underlying process. Second, using the Hybrid model, we show that empirical data collected from a web-based experiment are governed by perseverance rather than asymmetric learning. Finally, we apply the Hybrid model to two open datasets in which asymmetric learning was reported. As a result, the asymmetric learning rate was validated in one dataset but not another.

Project description:Small group work embraces independent study and interactive learning, which enhance knowledge acquisition and skills. Self-directed learning (SDL) and problem-solving (PS) are essential skills in the development of the nursing profession. During the coronavirus pandemic, virtual learning was indispensable. However, little is known about how students develop SDL and PS abilities through online learning through group work. To evaluate the effects of the online intervention on SDL and PS abilities through interactive group work. A randomised waitlist-control trial was carried out. A structured intervention using problem-based learning (PBL) as a guideline was used to direct student learning in small group work. Assessments were scheduled at Time 0 (baseline), Time 1 (8th week), Time 2 (16th week), and Time 3 (28th week). The mean student age was 21.45 (SD = 0.86). About 78% of students were female. There was no significant difference in demographic characteristics and analysis at the baseline. Students in the intervention group reported greater improvement in the SDLRS and PSI at the 8th week, whereas those in the waitlist control group reported greater improvement in the SDLRS and PSI at the 16th week. Sustained effects in the SDLRS and PSI were observed in both the intervention and waitlist control groups at the 16th and 28th weeks, respectively. A repeated-measure analysis was performed to compare the SDLRS and PSI in different periods and revealed statistically significant results (p < 0.001) in all subscales of SDLRS and PSI in the four study periods. The guidelines appear to be an effective treatment for SDL and PS ability enhancement with sustainable effects through interactive group work. The guidelines with explicit instructions and learning objectives provide directions and guidance to students to learn more effectively. The educator plays a vital role in facilitating the students' SDL and PS ability improvement.
