  3. Step I: Standardized Test Item In 1994, a new tomato variety that ripens slowly was developed by a laboratory technique that did not involve methods of natural reproduction. This new variety contains a section of a DNA molecule not found in the tomato from which it was originally developed. Which technique was most likely used to develop this new variety of tomato? 1 amniocentesis 3 genetic engineering 2 cross-pollination 4 karyotyping NavigationPage

  4. Step I: Test Item Type 1. What type of test item did you select? • Multiple Choice NavigationPage

  5. Step I: Test Item Structure 1. For a Multiple Choice Test Item: • Stem: Describes the production of a new species of tomato and asks what method was used for the development of this tomato. • Diagram: None for this question. • Distractors: 1,2,4. Genetic terms, but not appropriate. • Correct answer choice: 3. Genetic engineering • What makes this the correct choice?: This is the only choice where human intervention in the genes of the tomato is possible. NavigationPage

  6. Step I: Embedded Concepts & Process Skills Concepts and Big Ideas DNA structure Genes Manipulating genes by bioengineering Process (Inquiry or problem solving) Skills Students will be able to deduce that the processes involved in the description of the development of the new variety of tomato in the question point to genetic manipulation through genetic engineering. Webb’s Knowledge Level Skill/Concept NavigationPage

  7. Step II: Connections to State Curriculum Framework • CLE 3210.4.7 Assess the scientific and ethical ramifications of emerging genetic technologies. • SPI 3210.T/E.3 Evaluate the overall benefit to cost ratio of a new technology. • SPI 3210.4.9 Evaluate the scientific and ethical issues associated with gene technologies: genetic engineering, cloning, transgenic organism production, stem cell research, and DNA fingerprinting.
