  1. Performance and Portfolio Assessment

  2. Performance Assessment • An assessment in which the teacher observes and makes a judgement about a student’s demonstration of a skill or competency in creating a product. • Similar terms include: • authentic assessment. • alternative assessment. • portfolio assessment

  3. Performance Assessment Techniques • Individual Projects. • Group Projects. • Interviews and Oral Presentations. • Constructed Response Questions. • Essays. • Experiments. • Demonstrations.

  4. Performance Assessment TechniquesIndividual Projects • Comprehensive demonstrations of skills or knowledge. • Usually require student initiative and creativity. • Trained judges (often teachers) score projects against predetermined standards of quality. • Science fair projects areexamples.

  5. Performance Assessment TechniquesGroup Projects • Similar to individual projects. • A number of students work cooperatively on a complex problem. • Trained judges (often teachers) score projects against predetermined standards of quality.

  6. Performance Assessment TechniquesInterviews/Oral Presentations • Allow verbalization of knowledge. • Interviews are particularly effective with younger children. • Examples of usage include foreign language assessment, and • Solutions to math or science problems.

  7. Performance Assessment TechniquesExperiments • Primarily used for assessing learning in science. • Several national organizations (e.g., AAAS, NSTA, NSF) advocate the use of experiments in classroom assessment of science concepts. • Again, trained judges (often teachers) score projects against predetermined standards of quality

  8. Performance Assessment TechniquesDemonstrations • Give students the opportunity to show their mastery of subject-area content and procedures. • In physics, for example, use pulleys, gears, and inclined planes to move objects.

  9. Performance Assessment TechniquesPortfolios • Collections of student work provide a portrait of individual performance over time. • Typically, students are asked to evaluate the work they select for inclusion.

  10. Advantages Assessment of complex, higher-order learning targets. Students actively engaged in learning while being assessed. Forces teachers to use multiple criteria. Limitations Weaker reliability. Limited sampling of learning targets. Time-consuming. Not good for assessing knowledge learning targets. Performance Assessment:Advantages and Limitations

  11. Performance Assessment:Most Serious Limitation Limited Generalizability • Students respond to fewer tasks. • Makes it difficult to draw inferences about general abilities. • If the performance is successful can we infer that the student would do well on other tasks? • If performance is unsuccessful can we infer that the student would do poorly on other tasks?

  12. Performance Assessments:Three essential components • Popham contends, and most experts agree, that a performance assessment should contain the following three components: • Multiple criteria. • Pre-specified quality standards. • Judgmental appraisal. • In addition, performance assessments can be either simulated or authentic.

  13. Performance Assessment:Components (Popham) • Identify the purpose for the assessment. • Identify the learning target. • Identify activities that illustrate acquisition of the targeted capability. • Identify the types of evidence needed to infer skill acquisition. • Identify the standards to be used. • Place all this in the rubric.

  14. Performance Assessment:Evaluating the Rubric • Does it identify critical components of the learning target? • Does it identify “observable” behaviors or outcomes? • Is it appropriate for the students being assessed? • Does it apply across contexts that call for similar behaviors? • Does it specify levels of accomplishment?

  15. Vehicles for RecordingEvidence of Skill Acquisition • Rating Scales • Assess the degree or adequacy of attainment of the learning target. • Checklists • Assess presence or absence of skill acquisition. • Anecdotal Records • Assess atypical or unusual behaviors on selected children for future reference.

  16. Advantages Authenticity. Show growth. Empower students. Foster communication. Great instruc-tional tool. Limitations Many uses of classroom assessment are not served well with portfolios. Time consuming. Psychometric problems: with validity. with reliability. Portfolios:Advantages and Limitations

  17. Portfolio Assessment Assessment or instruction aid? Types of portfolios: Purposeful portfolios. Document progress. Showcase accomplishments. Evaluate student status. Work-sample portfolios ( Document typical performance). Appraising portfolios (Scored w/ a rubric).
