Question 7 Where on the continuum is the ideal classroom ? Question 8 Where on the continuum is your classroom? Explore What’s up with Termites? 1. On a sheet of paper, draw two circles near each other on the center of the page. 2. Release termites onto paper. 3. Keep creatures safe. I shall collect them in their original habitat. 4. What do you observe about termite behavior? 5. Develop a question your group could explore if you had more time. (15 minutes - select a timekeeper) 1. Develop 3 possible goals/ objectives for this ‘inquiry’ 2. Develop an assessment appropriate for one of the goals/objectives. Team Written response. Overhead. Reporter Recorder Timekeeper - (10 minutes) Checker - Explain What is assessment? Data collection with the purpose of answering questions about… students’ understanding students’ attitudes students’ skills instructional design and implementation curricular reform (at multiple grainsizes) Why do assessment? Improve student learning and development. Provides students and faculty substantive feedback about student understanding. Challenge to use disciplinary research strategies to assess learning. Assessment Guidelines for thinking about research... What did students learn? (assessment data) Why did students respond a particular way? (research) What are the working hypotheses or questions? What has already been done? Literature says... How and why to select methods? Conduct study... How to analyze and interpret data? What do the results mean? Are findings valid and generalizable? Research Data collection Assessment Gradient High Ease of Assessment Multiple Choice, T/F Diagrams, Concept maps, Quantitative response Short answer Low Potential for Assessment of Learning Essay, Research papers/ reports Low High Oral Interview Identify desired outcomes Determine acceptable evidence Design learning experiences and instruction Wiggins and McTighe 1998 Objective (outcome): Students will demonstrate understanding of evolution by natural selection. Problem (evidence) Write a scenario that explains the phenotypic changes in the tree and the animal. Use your understanding of evolution by natural selection. Text How do we develop rubrics? 1. Describe the goal/objective for the activity, problem, task... 2. Select the assessment tasks aligned with goals 3. Develop performance standards 4. Differentiate levels of responses based on clearly described criteria 5. Rate (assign value) the categories Scoring Rubric for Quizzes and Homework Level of Achievement Exemplary (5 pts) General Approach • Addresses the question. • States a relevant, justifiable answer. • Presents arguments in a logical order. • Uses acceptable style and grammar (no errors). Comp rehension • Demonstrates an accurate and complete understanding of the question. • Backs conclusions with data and warrants. • Uses 2 or more ideas, examples and/or arguments that support the answer. Adequate (3 pts) • Does not address the question explicitly, although does so tangentially. • States a relevant and justifiable answer. • Presents arguments in a logical order. • Uses acceptable style and grammar (one error). • Demonstrates accurate but only adequate understanding of question because does not back conclusions with warrants and data. • Uses only one idea to support the answer. • Less thorough than above. Needs Improveme nt (1 pt) • Does not address the question. • States no relevant answers • indicates misconceptions. • Is n ot clearly or logically organized. • Fails to use acceptable style and grammar (two or more errors). • Does not demonstrate accurate understanding of the question. • Does not provide evidence to support their answer to the question. No Answer (0 pts) Advantages of Scoring Rubrics Improve the reliability of scoring written assignments and oral presentations Convey goals and performance expectations of students in an unambiguous way Convey “grading standards” or “point values” and relate them to performance goals Engage students in critical evaluation of their own performance Save time but spend it well Limitations of Scoring Rubrics Problem of criteria Problem of practice and regular use Scoring Rubric website http://www.wcer.wisc.edu/nise/cl1/flag/ Sample Rubrics for Environmental Science http://www.msu.edu/~ebertmay/isb202/home.html What Type of Learning? Bloom (1956) Cognitive Domain of Educational Objectives 6 categories Knowledge Comprehension Application Analysis Synthesis Evaluation Condense to 4 - easy to work with Cognitive Levels Knowledge - remember Comprehension and Application grasp meaning, use, interpret Critical Analysis - original thinking, open-ended answers, whole to parts, parts to whole, evaluation Synthesis - make connections, evaluate Model for Learning - System So what is a concept? 1. Take a piece of paper -- one of the ‘dino-tree’ responses will work-2. Fold it in half. 3. On the top half, draw a bicycle. 4. On the bottom half, describe bicycle in writing. 5. Which is a better representation of the concept ‘bicycle’? 6. Would a concept map be “best”? Concepts are... Lexical Concept Maps are represent connected with has has Structure Hierarchy is constructed with Assessment Concepts Knowledge or Understanding Visual Diagrams Or Models Used for display Linking Words Organization Context promotes Reflection & Learning Prior Knowledge New Information www.ctools.msu.edu Robo Grader in Action Student’sText Concept Map For a course you teach ..... 1. Select a concept that is critical for your students to understand. 2. Identify 4 or 5 subconcepts that are important to understanding that concept e.g., DNA - Gene- Chromosome - Enzyme 3. Arrange them by rank order - top most general, bottom most specific 4. Add linking lines to make connections between two concepts 5. Add linking words that describe the relationship between two concepts Pre-Posttest Analysis Does active, inquiry-based instructional design influence students’ understanding of evolution and natural selection? Alternative Conceptions: Natural Selection ■ Changes in a population occur through a gradual change in individual members of a population. ■ New traits in species are developed in response to need. ■ All members of a population are genetically equivalent, variation and fitness are not considered. ■ Traits acquired during an individual’s lifetime will be inherited by offspring. Explain the changes that occurred in the tree and animal. Use your current understanding of evolution by natural selection. (AAAS 1999) Misconception: individuals evolve new traits % of Students n=80; p<.01 Misconception: evolution is driven by need % of Students n=80; p<.01 In guppy populations, what are the primary changes that occur gradually over time? a. The traits of each individual guppy within a population gradually change. b. The proportions of guppies having different traits within population change. c. Successful behaviors learned by certain guppies are passed on to offspring. d. Mutations occur to meet the needs of the guppies as the environment changes. Anderson et al 2002 Posttest: Student responses to mc % of Students n=171 * Animal/Tree Posttest: Gain in student understanding of fitness % of Students n=80; p<.01 Design Experiment Quantitative Data Qualitative Data Ebert-May et al. 2003 Bioscience Question How do assessment questions help us determine students’ prior understanding and progressive thinking about the carbon cycle. Instructional Design • Two class meetings on carbon cycle (160 minutes) • Active, inquiry-based learning – Cooperative groups – Questions, group processing, large lecture sections, small discussion sections, multi-week laboratory investigation – Homework problems including web-based modules • Different faculty for each course – One graduate/8-10 undergraduate TAs per course Experimental Design Two introductory courses for majors: Bio 1 - organismal/population biology (faculty A) Bio 2 - cell and molecular biology (faculty B) Three cohorts: Cohort 1 Bio 1 (n=141) Cohort 2 Bio1/Bio2 (n=63) Cohort 3 Other/Bio2 (n=40) Assessment Design Multiple iterations/versions of the carbon cycle problem Pretest, midterm, final with additional formative assessments during class Administered during instruction Semester 1 - pretest, midterm, final exam Semester 2 - final exam Grandma Johnson Problem Hypothetical scenario: Grandma Johnson had very sentimental feelings toward Johnson Canyon, Utah, where she and her late husband had honeymooned long ago. Her feelings toward this spot were such that upon her death she requested to be buried under a creosote bush overlooking the canyon. Trace the path of a carbon atom from Grandma Johnson’s remains to where it could become part of a coyote. NOTE: the coyote will not dig up Grandma Johnson and consume any of her remains. Analysis of Responses Used same scoring rubric (coding scheme) for all three problems - calibrated by adding additional criteria when necessary, rescoring: Examined two major concepts: Concept 1: Decomposers respire CO2 Concept 2: Plants uptake of CO2 Explanations categorized into two groups: Organisms (trophic levels) Processes (metabolic) Coding Scheme Code Organisms Code P rocesses and pathways 1 Decomposers IA Cellular Respiration IB Release CO IIA P athway of Carbon 2 P rimary producers 2 IIA _1: through Air IIA _2 : through Root IIA _3 : no mention about pathway 3 4 Herbivore Carnivore IIB Make Glucose II C P hotosynthesis III Respiration (glycolysis, Kreb cycle) IV Respiration (glycolysis, Kreb cycle) Correct Student Responses (%) Cellular Respiration by Decomposers Bio1/Bio2 Other/Bio2 Friedmans, p<0.01 Correct Student Responses (%) Pathway of Carbon in Photosynthesis Bio1/Bio2 Other/Bio2 Friedmans, p<0.05 Question 9 True or False? Assessing student learning in science parallels what scientists do as researchers. Parallel: ask questions Description: -What is happening? Cause: -Does ‘x’ (teaching strategy) affect ‘y’ (understanding)? Process or mechanism: -Why or how does ‘x’ cause ‘y’? Parallel: collect data We collect data to find out what our students know. Data helps us understand student thinking about concepts and content. We use data to guide decisions about course/curriculum/innovative instruction Parallel: analyze data Quantitative data - statistical analysis Qualitative data break into manageable units and define coding categories search for patterns, quantify interpret and synthesize Valid and repeatable measures Parallel: peer review Ideas and results are peer reviewed formally and/or informally.
