  • 1. Unit Plan Title: Design and Sketching Unit Length: 5 weeks Written by: Jim Roland Subject/Grade: 8th Grade Technology Standard 5: Students will apply technological knowledge and skills to design, construct, use, and evaluate products and systems to satisfy human and environmental needs. Performance Indicators: 1: Identify needs and opportunities for technical solutions. 3: Generate several ideas for alternative solutions and choose one optimal solution. 4: Develop plans and construct a model of the solution. 7: Use a variety of hand tools and machines. 11: Access needed information from various Internet sites. 15: Select appropriate technological systems. 20: Understand the contributions of people to technological development. 22: Describe how outputs can be desired, undesired, expected, and unexpected. Rationale: To promote Technological Literacy, PLTW has justified the importance of Design and Modeling. Students will learn the content of this curriculum while strengthening skills of literacy to become better learners. The application of content learned will be the greatest learning experience for students through several activities. Launch: Introduction to students of the teacher and course through 20 questions activity. Introduce course concepts, rules, and procedures through Family Feud activity. Ask students to list all of the technologies they can and then proceed by organizing them into appropriate systems and discuss the systems model. Relate technology to Science and other content familiar to students. To begin sketching portion, launch Pictionary to demonstrate the need for graphic communication. Essential Question: Why are sketching and technical drawing skills necessary for industry and society? Critical Thinking Skill: Error Analysis Sub Skills: Abstracting, Problem Solving, Systems Analysis Assessments: Formative: Daily Bell Ringer, Quizzes, Homework, Activity Participation, Daily Participation Summative: Unit Quiz Vocabulary: NYS Test: Elaborate, Best Describes, Associated
  • 2. Unit Vocab: Energy, system, transportation, communication, manufacturing, biotechnology construction, production, resources, measurement, design, brainstorm, model, invention, impact, innovation, conditions, goal, capital, information, machines, visualization, shape, texture, design brief, isometric, orthographic, perspective, three-dimensional, performance indicator, objective, technology Guiding Questions: Compare the differences of Science and Technology. Explain what a system is. Defend the need for measurement. Identify the unit used to measure in the U.S. Contrast the differences between open and closed-loop systems. Categorize the systems within production. Dispute an invention versus an innovation. Interpret what is the scientific method? Theorize how you solve everyday problems. Predict what paper is used most to communicate an idea. Distinguish what detail is shown in an orthographic drawing compared to an isometric. Student Engagement: participation in activities, observation throughout direct instruction, accountability by asking all students for answers randomly, answer individual questions, include students throughout instruction as helpers or assisting teachers, group or teamwork Meaningful Use (real world application): Students will apply measuring skills to relate inch units to real world objects. Through classroom measurement, students will estimate sizes and proportions. Students will practice graphic communication to improve their abilities to share ideas with others. Students will analyze and realize the impacts, of technology, around them have had on their lives and society. Materials/Resources: ruler game, handouts, drawing manipulatives, display blocks, How did it go?: Excellent for measurement. Students understand the English system of measure far better than last year. Measurement did take more time than expected though. Basic sketching is good but more advanced pictorial sketching is weak. Lessons were effective but developmentally, students have difficulty with spatial literacy. Pictionary launch for sketching and history of measure activity were both great and well received by students. What changes?: Next year I may start the unit immediately with very little classroom introduction and expectations. Perhaps I will stretch the measurement portion out across the entire semester instead of just within a block of a couple weeks. I will plan more time for sketching, especially pictorial drawing. Why different?: By starting the year immediately with content, students realized that there were high expectations and rules only had to be shared in a short discussion. By starting content immediately, there is more time for teaching, rather than explaining rules, etc. Discussing measurement throughout the entire year will reinforce learning and promote deeper understanding. More time for pictorial drawing is needed because students at this age have difficulty with spatial literacy.
