A student solved the following problem and made an error:

“prove” 3 = 0. can you spot the mistake?

d equals square root of quantity x sub 2 minus x sub 1 squared plus quantity y sub 2 minus y sub 1 squared, d equals square root of quantity 0 minus 2 all squared plus quantity 2 minus 4 all squared, d equals square root of negative 2 squared plus negative 2 squared, d equals square root of 4 plus 4
d equals square root of quantity x sub 2 minus x sub 1 squared plus quantity y sub 2 minus y sub squared, d equals square root of quantity 2 minus 4 all squared plus quantity 0 minus 4 all squared, d equals square root of negative 2 squared plus negative 4 squared, d equals square root of 4 plus 16, and finally d equals square root of 20.

PBL is a student-centered pedagogy in which students learn about a subject by solving an open-ended problem in trigger content. The PBL process does not emphasize problem solving with a predetermined solution, but it does allow for the creation of other valuable skills and characteristics. This includes improved community coordination and connectivity, as well as information acquisition. The PBL method was created for medical education and has since been expanded to include other learning programs. Learners are able to acquire skills that will be useful in their future practice as a result of this process. It improves critical thinking, literature retrieval, and promotes continuous learning in a group setting.
Working in small groups of learners is an essential part of the PBL tutorial method. Each student takes on a formal or informal position within the community, which they often switch. It focuses on the students’ ability to construct their own learning by reflection and reasoning. Clarifying words, identifying problem(s), brainstorming, structuring and hypothesis, learning goals, independent research, and synthesis are all part of the Maastricht seven-jump method. [1] To put it another way, it’s figuring out what they already know, what they need to know, and how and where they can get new knowledge that could help them solve the problem. The tutor’s job is to make learning easier by assisting, directing, and tracking the learning process. [2] The tutor’s goal is to increase students’ interest in dealing with problems while also broadening their knowledge. Constructivism is used to guide this method. PBL reflects a paradigm shift from conventional lecture-based teaching and learning philosophy[3]. Teaching PBL is somewhat different from conventional classroom or lecture teaching, and small group learning also necessitates more planning time and resources. PBL can help students learn and understand complicated concepts and theories like STEM, engineering design issues, and so on. [number four]

Many engineering, math, and science teachers have students solve “problems.” But are their students working on real problems or just practicing? The former places a premium on strategic thought and decision-making abilities, while the latter merely involves the implementation of previously learned procedures. True problem solving is the process of applying an unknown approach to a problem that has a complex set of conditions and that the problem solver has never seen before in order to come up with a suitable solution.
