YOUR TOPIC GOES HERE Plant Responses Your Subtopics Go Here Changes resulting from internal and external stimuli. Tropism Hormones Photoperiodism Students perform a task instead of picking an answer from a multiple choice question. Example: A student tying their shoe as opposed to writing an essay explaining how it is done.

YOUR TOPIC GOES HERE Tropism Your Subtopics Go Here A response to a stimulus resulting in growth change; can be positive (toward stimulus) or negative (away from stimulus). There are differences between traditional testing and performance assessment. Using performance assessment students can better communicate what they know. Performance assessments are designed to judge student abilities to USE specific knowledge and research skills. Most performance assessments require the student to manipulate equipment to solve a problem or make an analysis. Rich performance assessments reveal a variety of problem solving approaches, thus providing insight into a student's level of conceptual and procedural knowledge. “Young scientists for example, may not be able to repeat a lengthy definition. However, they can carry out an investigation and explain, in their own words, how and why it worked the way it did.” Flynn, L. (2008). In praise of performance-based assessment. Science and Children, 45(8), 32-35.

YOUR TOPIC GOES HERE Tropism Your Subtopics Go Here Some plants grow around objects they touch. Thigmotropism There are differences between traditional testing and performance assessment. Using performance assessment students can better communicate what they know. Performance assessments are designed to judge student abilities to USE specific knowledge and research skills. Most performance assessments require the student to manipulate equipment to solve a problem or make an analysis. Rich performance assessments reveal a variety of problem solving approaches, thus providing insight into a student's level of conceptual and procedural knowledge. “Young scientists for example, may not be able to repeat a lengthy definition.

YOUR TOPIC GOES HERE Tropism Your Subtopics Go Here Plants may grow toward a light source. Phototropism Gravity – downward growth of roots is a positive response; upward growth of stem is a negative response. Gravitropism There are differences between traditional testing and performance assessment. Using performance assessment students can better communicate what they know. Performance assessments are designed to judge student abilities to USE specific knowledge and research skills.

Your Subtitle Goes Here Life THE TEMPEST Watch 10 minutes of Discovery’s LIFE. Can you identify different types of tropism? Your Subtitle Goes Here

YOUR TOPIC GOES HERE Plant Hormones Your Subtopics Go Here They control growth changes triggered by tropisms. Ethylene – gas produced by many plants and released into the air. Can promote cell growth between leaf and stem resulting in leaf drop. Stimulates fruit ripening process. By answering these questions, you can decide what type of activity best suits you assessment needs. After you define the purpose of the assessment, you can make decisions concerning the activity. There are some things that you must take into account before you choose the activity: time constraints, availability of resources in the classroom, and how much data is necessary in order to make an informed decision about the quality of a student's performance (This consideration is frequently referred to as sampling.). Airasian, P.W. (1991). Classroom assessment. New York : McGraw-Hill.

YOUR TOPIC GOES HERE Plant Hormones Your Subtopics Go Here Auxin – helps with stem elongation and root formation Auxin causes plants to bend toward the light. Gibberellins – assists with plant germination and development Cytokinins – also cause fast growth through rapid cell division. Abscisic acid – slows or stops plant growth.  Look on page 141 in your textbook for a visualization of these hormones. Tasks can have firm structure and direction while others can be flexible and allow the student to be more objective. Performance based assessment can also be applied to students individually or with partners and group projects. Examples: Specifics: The egg drop in physics, tying your shoes, writing a business letter General: Science labs, dioramas, poetry Telling your students that you are “testing” them in a various area may turn them off. The word “testing” has a negative connotation. Going about the given assessment candidly will engage students in a more positive manner. While learning objectives are essential, performance assessment involves higher-level thinking and students will be on different levels. To help solve this problem, differentiated instruction may need to be implemented.

YOUR TOPIC GOES HERE Photoperiodism Your Subtopics Go Here Carnation Plants sensitivity to daily hours of light and darkness for flower production Long-day plants – need less than 10-12 hours of darkness to produce flowers. Tasks can have firm structure and direction while others can be flexible and allow the student to be more objective. Performance based assessment can also be applied to students individually or with partners and group projects. Examples: Specifics: The egg drop in physics, tying your shoes, writing a business letter General: Science labs, dioramas, poetry Telling your students that you are “testing” them in a various area may turn them off.
