Summative Evaluation The Evaluation after implementation Dick and Carey: Chapter 12
Involves _______ data Collecting Analyzing Summarizing
For the purpose of Giving decision makers information on the effectiveness and efficiency of instruction
Effectiveness of Content (should be criterion referenced) • Does the instruction solve the problem? • Was the criterion established prior to evaluation? • Was the criterion established in conjunction with the needs assessment?
Specifically • Did the learners achieve the objectives? • How did the learners feel about the instruction? • What were the costs? • How much time did it take? • Was the instruction implemented as designed? • What unexpected outcomes were there?
Alternative Approaches to Summative Evaluation Objectivism Subjectivism
Objectivism • Based on empiricism • Answering questions on the bases of observed data • Goal based and replicable, uses the scientific method
Subjectivism • Employs expert judgment • Includes qualitative methods • observation and interviews (evaluate content) • “Goal Free” • evaluators haven’t a clue about the goals
Objectivism (limitations) • Examine only a limited number of factors • May miss critical effects
Subjectivism (limitations) • Are not replicable • Biased by idiosyncratic experiences, perspectives, or the people who do the evaluation • May miss critical effects
Designer Role in Summative Evaluation? Somewhat controversial
Timing of Summative Evaluation? Not in the first cycle
Formative Design Reviews Expert Reviews One-to-one Eval. Small Group Eval. Field Trials Ongoing Eval. Summative Determine Goals of the Evaluation Select Orientation Select Design Design or Select Evaluation Measures Collect Data Analyze Data Report Results Summary Diagram
Determine Goals of the Evaluation • What decisions must be made as a result of the evaluation? • What questions will best answer these questions? • How practical is it to gather data to answer a question? • Who wants the answer to a question? • How much uncertaintyis associated with the answer?
Select Orientation of Evaluation • Goal-based or goal-free • A middle ground? • Quantitative or qualitative appropriate? • Experimental or naturalistic approach?
Select Design of Evaluation • Describes what data to collect • When the data will be collected • And under what conditions • Issues to consider: • How much confidence must we have that the instruction caused the learning? (internal validity) • How important is the generalizability? (external validity) • How much control do we have over the instructional situation?
Design or Select Evaluation Measures • Payoff outcomes • Is the problem solved? • Costs avoided • Increased outputs • Improved quality • Improved efficiency
Design or Select Evaluation Measures (2) • Learning Outcomes • Use instrument you’ve already developed for the summative evaluation • But measure the entire program
Design or Select Evaluation Measures (3) • Attitudes • Rarely the primary payoff goals • Ask about learner attitudes toward • learning • instructional materials • subject matter • Indices of appeal • attention, likeableness, interest, relevance, familiarity, credibility, acceptability, and excitement
Design or Select Evaluation Measures (4) • Level of Implementation • degree to which the instruction was implemented • Costs • Cost-feasibility • Cost-effectiveness
Alternative Designs • Instruction then posttest • Pretest then instruction then posttest
The Report • Summary • Background • Needs assessment, audience, context, program description • Description of evaluation study • Purpose of evaluation, evaluation of the design, outcomes measured, implementation measures, cost-effectiveness info., analysis of unintentional outcomes
The Report (continued) • Results • Outcomes, implementation, cost-effectiveness info., unintentional outcomes • Discussion • causal relationship between program & results • Limitation of study • Conclusion & Recommendations
Summary • Summative evaluation is after implementation • Limitations of subjective and objective evaluation • What to include in the report
