Deals with knowledge are experienced informations. It is a matter of active doing that involves the use of the body and the handling of material. The theory states that students must not only be told to study but they must be taught how to study effectively and be given drills to apply the knowledge that they have learned in actual setting. Therefore they can gain knowledge more efficiently. Learning by doing is the way most folks ultimately learn anything and everything. If knowledge is power‚ then

The Affective Filter Meghan Borman Texas Woman’s University There are many processes that second language learners can use to acquire a second language. One process involves the Affective Filter Hypothesis. The Affective Filter Hypothesis is one of Krashen’s five hypotheses that addresses the relationship between second language acquisition and affective filters or social-emotional variables. In this hypothesis‚ the lower the affective filter is the more likely a learner will acquire a second

The Affective Filter Hypothesis Nowadays‚ studying a second language becomes more and more important‚ so how to grasp the second language well and quickly becomes a significant topic. Since I learned some related theory from this weeks class‚ I found one of the five hypotheses of the natural approaches which attract my attention. In the 1970s‚ Stephen D. Krashen put forward a famous theory Affective Filter Hypothesis‚ and it helps teachers and learners to have a great progress on learning second

The Carbon Cycle The element Carbon is the principle block for the organic compounds that make up life. This is because the study of the Carbon Cycle draws upon theories from biology‚ chemistry‚ geology and oceanography in order to understand the movement of carbon throughout the atmosphere‚ hydrosphere‚ and geosphere. Carbon is made up of four electrons that are able to form with each other; this causes the many different forms of carbon. The most popular form of carbon is carbon dioxide; this
