Chemistry is Hard Why?
Blooms Taxonomy l Psychologist who studied how people think l Broke thinking into levels of complexity l Each level required using the information below l The lowest level is knowledge- memorizing textbook definitions l Easiest but least useful
Blooms Taxonomy l Understanding- being able to put the knowledge into you own words l Application- being able to use the information in new situations l Analysis- breaking the information into meaningful pieces l Synthesis- being able to put information together to generate new learning
Blooms Taxonomy l Evaluation- using all the information, making and defending value judgments about the information.
Knowledg e Understanding Application Analysis Synthesis Evaluation
What does this have to do with chemistry? l In the past, many of your classes relied on memorization. l Knowledge level l Chemistry focuses on the higher levels. l I dont ask you to memorize a lot of terms l I ask you to learn processes and techniques and then apply them to novel situations
Word Clues l How hard do I have to think? l Knowledge – Who, what, where, when, tell, label, define, select, choose, identify, describe, recall l Comprehension – Show, explain, discuss, classify, recognize, summarize, paraphrase
Word Clues l Application – Use, solve, teach, relate, explain, predict, compute, illustrate, simulate, demonstrate l Analysis – Probe, dissect, outline, compare, organize, diagram, distinguish, investigate, categorize
Information Processing Theory l Describes how we learn something new
Information Processing Theory l Filters what we know l What we pay attention to moves on Sensory Register Less than a second
Information Processing Theory l Room for 7 things (on average) l Less than a minute Sensory Register Less than a second Short- term Memory
Information Processing Theory l If we process it further it stays with us l To learn something requires practice Sensory Register Less than a second Short- term Memory Long Term Memory
Memory Techniques l Rehearsal- repetition l Chunking- grouping the information into meaningful categories l Remembering general rules is easier than every specific instance l We learn best by connecting new knowledge with old knowledge l ROY G BIV
Another Reason Chemistry is hard l Requires math skills. l Uses math to explain l Prerequisite l Algebra is used in this class regularly. l Used to describe the world around us
What can you do?
