     Critical thinking is an important skill that can increase students' ability to learn in any situation. This can be

applied to traditional education, online education, or directly in a career related role. Many teachers find it such

a valuable skill that they give their students a critical thinking question every day. Developing this ability can

mean the difference between "just passing a course" and "understanding the material well enough" so that what

students learn from it will follow them throughout their life.

     Some characteristics of a critical thinker that teachers should encourage are:

     -asking questions as a reaction to something read or discussed;

     -determining the "deeper meaning" of a particular passage or topic;

     -providing input and opinions to topics as a direct result of analysis and research;

     -reasoning in an effort to develop an argument of your own opinion.

     It is important for a student to understand more than definition (定义). One way to truly understand an idea

is to have hands-on practice, and to apply concepts learned in a textbook. Such "mini-examples" will interest a

student and improve their understanding of a topic. This is how lifelong skills can be developed.

     Teachers that use critical thinking practices in the classroom can "go above and beyond" by asking questions

that promote a greater comprehension of the material. Instructors should be able to challenge students and

create an environment where they are analysing material and gaining a better understanding. This will make the

classroom move in a direction for learning. It can also help students to stay interested in the course material, as

they always have a new concept to consider.

     At the same time, students benefit greatly from developing critical thinking skills. When learned early on,

these skills can be used throughout their college education. Students can understand how to consider a topic,

analyse it, and discuss it from different points of view. These are skills that will benefit them when they are

part of the workforce as well.
