Nonscience majors often do not respond to traditional lecture-only biology courses. However, these students still need exposure to basic biological concepts. To accomplish this goal, forensic science was paired with compatible cell biology subjects. Several topics such as human development and molecular biology were found to fulfill this purpose. Another goal was to maximize the hands-on experience of the nonscience major students. This objective was fulfilled by specific activities such as fingerprinting and DNA typing. One particularly effective teaching tool was a mock murder mystery complete with a Grand Jury trial. Another objective was to improve students' attitudes toward science. This was successful in that students felt more confident in their own scientific abilities after taking the course. In pre/post tests, students answered four questions about their ability to conduct science. All four statements showed a positive shift after the course (p values ranging from .001 to .036, df = 23; n = 24). The emphasis on experiential pedagogy was also shown to increase critical thinking skills. In pre / post testing, students in this course significantly their performance on critical thinking assessment tests from 33.3% correct to 45.3% (p = .008, df = 4; n = 24).

Biology Lab

Polymerase chain reaction (PCR) and gel electrophoresis have become common techniques used in undergraduate molecular and cell biology labs. Although students enjoy learning these techniques, they often cannot fully comprehend and analyze the outcomes of their experiments because of a disconnect between concepts taught in lecture and experiments done in lab. Here we report the development and implementation of novel exercises that integrate the biological concepts of DNA structure and replication with the techniques of PCR and gel electrophoresis. Learning goals were defined based on concepts taught throughout the cell biology lab course and learning objectives specific to the PCR and gel electrophoresis lab. Exercises developed to promote critical thinking and target the underlying concepts of PCR, primer design, gel analysis, and troubleshooting were incorporated into an existing lab unit based on the detection of genetically modified organisms. Evaluative assessments for each exercise were aligned with the learning goals and used to measure student learning achievements. Our analysis found that the exercises were effective in enhancing student understanding of these concepts as shown by student performance across all learning goals. The new materials were particularly helpful in acquiring relevant knowledge, fostering critical-thinking skills, and uncovering prevalent misconceptions.

In writing classes, besides mastering the language items and writing rhetoric, students are required to use some high order thinking skills to be able to write academically. Hence, this study basically aims to see the effectiveness of the use of critical thinking skills on writing achievements of the Turkish EFL students. The purpose of the study is to see if online critical thinking treatment affects students� use of critical thinking skills in their writings. In addition, students� attitudes towards asynchronous learning tools during the study were observed. At the beginning and end of the study, 16 students in control group and 16 students in experimental group answered the questions in the critical thinking disposition scale. In addition to this, their writing performances were evaluated before and after the study. Meanwhile, experimental group students were exposed to 8-week online critical thinking treatment. The data gathered were statistically analysed and the results indicate that while the students� writing performances do not differ significantly before and after the online critical thinking treatment, it has significantly contributed to the studentS� use of critical thinking skills while writing.

In the approach to learning, teachers must be able to create an active, creative, effective, and funlearing. One of the learning approaches that can be used to create this active, creative, effectiveand fun learning in a group is cooperative learning. Jigsaw was particularly selected from varioustypes of cooperative learning. It was because it is used by researchers in science education, andless popular in social science education. Jigsaw arouse students' attitudes to learning, including inthe History subject. Jigsaw that is one ofthe types of cooperative learning models that encouragesstudents to be active and help each others in mastering the subject matter to achieve maximumperformance. The aim of the study was to see the different models of cooperative learning onstudents' critical thinking skills in the History subject. The method used was by using the teststatistics with analysis using Excel for Windows. To determine whether there is any differences,tests of paired data (Student's t-test) were comducted. If there are no significant differencesbetween the dependent variable for the pre-test, it will be used followed by ANOVA in the posttest. The results showed that there is a difference between the type of cooperative learning modeljigsaw with traditional learning in the study on the critical thinking skills of students in the Historysubject.

The Impact

Background: Scientific research processes are of capital significance in defining problems from a critical perspective, identifying the variables, determining the relationships between these problem variables, and finding solutions to existing issues. Aim: Based on this direction, the current study aimed to examine the effects of sports science students' attitudes towards scientific research methods course on their critical thinking skills considering various variables. Methods: The study group, determined by a simple random sampling method, comprised 412 students with an average age of 21.92, studying in sports sciences. "Attitude Scale Towards Scientific Research Course" and "Critical Thinking Skills Scale" were used to scale students' scientific research and critical thinking skills. Results: The study determined that while there was no significant difference between the students according to the gender variable, there were differences according to the department and class variables. Conclusion: As a result, there is a positive relationship between students' attitudes towards scientific research methods and their critical thinking skills.

A central goal of science education is to help students develop higher order thinking skills to enable them to face the challenges of life. Accordingly, science instructors are now urged to craft their classrooms such that they serve as not only spaces for disseminating information, but also an arena through which students are encouraged to think scientifically and develop critical-thinking skills. This project aimed to develop a workbook that helps postsecondary students learn endocrinology and engages them in critical thinking. Each of the five chapters focuses on a different topic rooted within core biological concepts relevant to endocrinology. Such topics were identified on cross-referencing seminal reports on science education. Tenants of Numrich’s Sequence of Critical-Thinking Tasks were used to guide the development of chapter sections with the intent of engaging students in critical thinking over time by way of practice and scaffolded guidance. Chapter sections of modeling, event sequencing, clinical application, research and communication, and simulation, target different skills presented in Numrich’s framework. Students’ learning, experiences, and behaviors were used to evaluate the workbook and inform the revision of the workbook into the publicly available second edition.

Comprehensive Information

Critical thinking skills are one of the four main competencies that must be empowered in the 21st-century learning. This study aimed to describe students' critical thinking skills through the application of blended-problem-based learning (PBL) in the Cell Biology course. The data sources of this research were 28 students who were taking Cell Biology Course in Department of Biology Education, Universitas PGRI Madiun. The research instruments used were 1) observation sheet, 2) interview guidelines, and 3) critical thinking skills test. The study was designed by applying blended-PBL on 12 topics. The data analysis was performed in descriptive qualitative. The results showed that the application of blended-PBL was able to train students to improve their critical thinking skills in term of how to answer the test given. However, further studies need to be done with a wider number of samples and material scope to get more comprehensive information.
