Problem-solving skills help students determine the source of a problem and find an effective solution. These are skills that help students identify and solve problems effectively and efficiently. Problem-solving is a process of overcoming difficulties that appear to interfere with the attainment of a goal. So, a teacher should develop problem-solving skills in students.Some problem-solving skills include- Active listening, Analysis, Research, Use of analogies, Creativity, Communication, Dependability, Establishing cause and effect of the problem, Decision making, Team-building, etc. Some basic characteristics of problem-solving skills are-These skills don't have rigidity.Learners practices different activities, teamwork, and group discussions to improve their skills.Learners use different ways to gain problem-solving skills, their thoughts are divergent.Different methods/functions are used by the teachers as well as learners, there is no fixedness in these skills.So that's why we can say that option (1) is the correct answer.?Additional InformationAnalysis: The first step to solving any problem is to analyze the situation. Your analytical skills will help you understand problems and effectively develop solutions.Analogies: Analogical reasoning is a kind of reasoning that is based on finding a common relational system between two situations, exemplars, or domains.Cause-effect relationship: By establishing the effects of the cause step by step, we can say that by dividing the problem into small chunks and learner can solve chunks and achieves targets.
