Management Theory Taxonomy Some would define management as an art‚ while others would define it as a science. "Management is not an exact science‚ but rather is a mix of art‚ scientific methodology‚ intuition‚ investigation‚ and most of all‚ experimentation" (Miller & Vaughan‚ 2001‚ Winter). "Management is not static. It is evolving‚ as are people who manage and are managed." (http://angel02.gcu.edu/AngeIUploads/ContentlMGT301 LORI assic/9668726CD47F4 EFAB1A77328734D41 EC/!ecture MG

Benjamin Bloom’s Cognitive Theory of Educational Objectives The Bloom’s taxonomy is a multi-tiered model of thinking. Bloom believed that humans operate on six levels of cognition which are knowledge‚ comprehension‚ application‚ analysis‚ and evaluation. Using these factors‚ I will seek to discuss the major points of bloom’s theory and how this cognitive theory may assist teachers in their classrooms. In 1956‚ Benjamin Bloom headed a group of educational psychologists who developed

Procedure: 1. The compass was placed on the lab table with no magnets nearby to identify what direction was north relative to the classroom. 2. On the ends of the variable gap magnet there were two small magnetic disks. One arm of the magnet was unscrewed and removed from its housing. A meter stick was placed on the and the arm was on its side parallel to the meter stick. The Gauss-Tesla meter was used to measure the field strength of the magnet. The probe attached to the meter was perpendicular
