EDF 6225 Exam 1 Full Exam ce - ANSWER Systematic approach for seeking & organizing knowledge about the natural world purpose of science - ANSWER ◦To achieve a thorough understanding of the phenomena under study ABA seeks to - ANSWER discover the real truths (not those held by certain groups, organizations, etc.) Three different types of investigations provide different levels of understanding - ANSWER 1. description 2. prediction 3. control description - ANSWER ◦Collection of facts about observed events that can be quantified, classified, & examined for possible relations with other known facts ◦Often suggests hypotheses or questions for additional research prediction - ANSWER ◦Relative probability that when one event occurs, another event will or will not occur ◦Based on repeated observation revealing relationships between various events ◦Demonstrates correlation between events ◦No causal relationships can be interpreted ◦Enables preparation control - ANSWER ◦Highest level of scientific understanding ◦Functional relations can be derived Specific change in one event (dependent variable).... Can reliably be produced by specific manipulations of another event (independent variable)... And the change in the dependent variable was unlikely to be the result of other extraneous factors (confounding variables) ◦Events can only really be "co-related" Nearly impossible to factor out all other possible "causes" attitudes of science - ANSWER - Definition of science lies within the behavior of scientists, not the instruments or materials they use - Only known as science due to an overriding idea of "scientific method" - Fundamental assumptions about the nature of events 6 attitudes of science - ANSWER 1. DETERMINISM 2. EMPIRICISM 3. EXPERIMENTATION 4. REPLICATION 5. PARSIMONY 6. PHILOSOPHIC DOUBT determinism - ANSWER - Assumption upon which science is predicted - Presumption that the universe is a lawful and orderly place in which all phenomena occur as the result of other events - Events do not just occur at will - Events are related in systematic ways empiricism - ANSWER - Practice of objective observation of phenomena of interest - What all scientific knowledge is built upon - "Objective" is the key to gaining a better understanding of what is being studied experimentation - ANSWER - Basic strategy in most sciences - Experiment: ◦Controlled comparison of some measure of the phenomenon of interest (dependent variable) under two of more different conditions in which only one factor at a time (independent variable) differs from one condition to another replication - ANSWER - The repetition of experiments to determine the reliability and usefulness of findings - Includes the repetition of independent variable conditions within experiments - Method for which mistakes are discovered parsimony - ANSWER - The idea that simple, logical explanations must be ruled out, experimentally or conceptually, before more complex or abstract explanations are considered - Help scientists fit findings within the field's existing knowledge base philosophical doubt - ANSWER - The continuous questioning of the truthfulness and validity of all scientific theory and knowledge - Involves the use of scientific evidence before implementing a new practice, then constantly monitoring the effectiveness of the practice after its implementation science relies on - ANSWER determinism as its fundamental assumption science's prime directive = - ANSWER empiricism science's basic strategy - ANSWER experimentation science's requirement for believability - ANSWER replication science's conservative value - ANSWER parsimony science's guiding conscience - ANSWER philosophica
