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.
Constructivist Theory (Jerome Bruner). A major theme in the theoretical framework of Bruner is that learning is an active process in which learners construct new ideas or concepts based upon their current/past knowledge.The learner selects and transforms information, constructs hypotheses, and makes decisions, relying on a cognitive structure to do so.ote that Constructivism is a very broad conceptual framework in philosophy and science and Bruner's theory represents one particular perspective.
