Because the world is shifting from know-how to know-where, critical thinking is one of the most crucial abilities of the 21st century. It is impossible for any one of us to keep up with the rate at which knowledge is doubling every 12 hours. This results in a large number of uncertain career possibilities and uncertain employable skills in the foreseeable future. Therefore, it is essential to foster a growth mindset in students by engaging them in classroom activities that equip them with 21st-century abilities such as critical thinking. This will prepare students to acquire and apply knowledge in accordance with the requirements of their work.
PBL (project-based learning) is an excellent instructional and evaluation technique for fostering critical thinking. Students can be given a list of projects to choose from, or they can be given a wide subject and allowed to choose any project that falls under that theme. As an illustration, students may be assigned hygienic practices as a theme and focus on hygienic cooking practices for households, or they may demonstrate an interest in hygienic practices in hospitals, etc. Students collaborate in groups to achieve a common goal. Since they have input and control over the project, they will put out their best efforts. It also resembles the gamification paradigm in that they collaborate to accomplish something. This also develops their communication skills, as they create rules, give assignments, check progress, and reflect on their work to enhance its quality and efficiency. They remark at each level on what worked and what did not, as well as what should be altered in order to continue. In addition, they receive comments from the instructor and their peers. As a result, they modify their strategies. PBL does take a significant amount of work on the side of the instructor, as the instructor must offer students with specific project expectations based on their zone of proximal development. It provides students with the opportunity to tackle a problem from the real world and allows them to exercise critical thinking and communication skills. As part of their summative evaluation, students are expected to present their projects to a larger audience. This will increase their confidence and sense of competence.
Social creation of knowledge is also an effective method for enhancing critical thinking abilities.
There is a wealth of knowledge available in a variety of mediums, including libraries, teachers, and peers.
Students might be prompted to make connections between their knowledge and other bodies of knowledge and to generate new meanings. By conducting a survey, students can collect information from doctors on widespread diseases in society, for instance. Additionally, they may gather information regarding hygienic behaviors via the Internet or libraries. Then, they can compile various forms of data from various sources to deduce the causes of particular diseases in society. They can also recommend preventative steps against certain disorders. They may be required to create booklets to increase societal awareness. They will work diligently because they recognize the importance of their work to the community. As learners must make sense of material from various sources and determine how the jigsaw pieces fit together, they will engage in a substantial amount of critical thinking throughout this process.
Debates are another essential method for enhancing critical thinking. Refer to my response to the second question for an example. Students can choose from a list of subjects and are given time to gather information from various sources in order to participate in the debate effectively. In the process of arguing, students become familiar with all sides of an issue and must understand a great deal in order to effectively refute the opposing side. As they develop arguments and counterarguments, debates can become highly engaging. In addition, this makes learning enjoyable because each student is held accountable. Otherwise, for certain activities, some students choose to remain unnoticed and passive by relying heavily on their classmates. Participants in the debate must study every argument and find counterarguments and statistics.
Creating models is also an essential method for practicing critical thinking. Models materialize the intangible form of abstract knowledge. Students must consider snippets of knowledge and determine how they fit together to form a model, which involves a substantial amount of effort. Organelles of the cell, for example, are undetectable to the naked eye and cannot be viewed using a simple microscope found in school laboratories. As a result, the majority of pupils are unable to envision them and have great difficulty relating their structures to their functions. However, if students are required to create a model of a cell, they will need to research its three-dimensional shapes. As they construct their model, students will use play-doh to make these forms. In this process, they will evaluate critically the relationship between the structures and functions of various organelles. In addition, the position of these organelles in the cytoplasm will aid in the learning of their coordination. All of these benefits metacognition. Students might be provided with a grading scheme or rubric to establish clear standards for their model. They may also be required to provide an oral presentation of their model and describe the construction process.
In order for students to promote their work online, they should be incentivized to leave a digital imprint through digital citizenship. Thus, their work will be accessible to a larger audience, and the likelihood that others will benefit from it will increase. In this way, they will appreciate their work more and exert greater effort for the greater good of society.
