Panic attacks and panic disorder may be caused by an imbalance of brain chemicals or a family history of panic disorder. They sometimes happen with no clear cause. Panic attacks may also be brought on by: 1  A health problem such as an overactive thyroid ( hyperthyroidism ), or heart or breathing problems. 2  Depression or another mood disorder. 3  Alcohol abuse. 4  Using too much nicotine or too much caffeine. 5  Taking certain medicines, such as those used to treat asthma and heart problems.
(1) Learning occurs when people construct their own knowledge by connecting new information with prior knowledge; (2) Learning grows out of social interaction; (3) Learning lasts when learners are actively engaged with information. Lectures can be part of a constructivist based lesson as long as it addresses these tenets. Certain practices such as well structured group work, reflection, and think-pair-share are also often reflective of constructivist theory.
David Kolb published his learning styles model in 1984 from which he developed his learning style inventory. Kolb's experiential learning theory works on two levels: a four stage cycle of learning and four separate learning styles. Much of Kolbâs theory is concerned with the learnerâs internal cognitive processes.
