Creativity consists in coming up with new and relevant ideas. To be a good and effective thinker, both kinds of thinki

Skills can often be divided into dom
19、ain-general and domain-specific skills. Thinking (cognition) goes beyond the acquisition of knowledge and includes the process(es) of knowing and reflecting on thinking (metacognition). A process can be defined as “a logical series of related transactions that converts input to results or output” .

Before taking the time to critically evaluate an issue, ask the question, “Who cares?” Questions help you explore di

Questions help you identify your goals and intentions.,,一、thinking is a process of asking and answering questions,When a writer or speaker has a conclusion she wants you to accept, she must present reasons to persuade you that

So, question comes from asking the reasons.,,Those three claims are each missing something. We may or may not agree with them, but in their current form they are neither weak nor strong.
