  • Review the workshop objectivesEmphasize intention (presentation of curriculum integration model) – curriculum is starting point, not ending point
  • So we have our overly general curriculum map. What are the natural connections between subject areas?Here’s a obvious one, right? In English, you learn to write persuasive compositions, how to evaluate credibility, in fiction and nonfiction. In fiction, there’s the unreliable narrator. In nonfiction, you need to vet source for bias, and so on. Both are directly related to being conducting and evaluating courtroom testimony. Sometimes though there doesn’t seem to be a connection. DNA, and circles? Doesn’t seem to go together. But hey, you know they are connected? They both can be used in the course of a criminal investigation. DNA sequencing can be used to convict or exonerate suspects, calculation of area and perimeter are used when establishing a search region. You know the suspect left the crime scene an hour ago in a car, you can calculate how far he could have traveled and then use that to establish a search reasonable area. And in the technical class, criminal investigation leads to trials and courtroom testimony. Using that real world context, you can bring link a large range of content topics. So, when looking at your own projects, some things to consider. What are new, different connections that might be made between subject areas, who can you go to for fresh look and new suggestions? From the other side, do you have connections that are kind of shoehorned in there? That happens, oh, we have to get US history in somehow. But the connection is weak. If you can’t make strong authentic connections, maybe they don’t belong, or maybe you need to consider rethinking the overarching unit theme. It’s hard to throw out a project that you did a lot of work on, especially if students find it fun. But if it’s just fun, and not covering real standards, or not hanging together cohesively, it’s probably not producing the measurable outcomes you want.
  • In NYS the course is called Drawing and Design for Production. Introduction to Engineering Design is a high school course that is appropriate for 9th or 10th grade students. IED is a foundation course. The course assumes no previous knowledge, but students should be concurrently enrolled in college preparatory mathematics and science.
  • Unit 1Tools that engineers use to solve problemsSteps in the design process ***Basic rules of technical sketchingMeasurement and statistics ***How to create a product from conception to reality
  • Unit 2Knowledge and use of CAD modeling software, including how toCalculate area, surface area, volume, and weight of 3D solids ***Properly document technical drawings ***Apply design process steps to solve a problem ***
  • Unit 3In this lesson students will*** identify visual, *** functional, or *** structural issues with their reverse-engineered products, ***initiate product improvements by writing design briefs, participate in group brainstorming sessions to develop creative ideas, use matrices to make design decisions, develop innovative solutions, and ***communicate their designs through technical reports.
  • It is important for the students to understand that an acceptable solution is one that fits the constraints and specifications of the design brief. There is no one right way to solve a design problem, but there is always a more functional, structurally sound, cost effective, visually pleasing, and environmentally friendly way.In this unit students will be grouped into virtual design teams based on their interests. Students will learn about group norms, establish rules of acceptable behavior, develop management strategies, and work across virtual boundaries to research and develop solutions to problems of their choosing.
  • Introduce two unitsExplain that they are not necessarily semester 1 and 2 Describe what each unit includes (have them open binder to examples, if necessary)
  • Review the workshop objectivesEmphasize intention (presentation of curriculum integration model) – curriculum is starting point, not ending point
  • Introduce first unit as culminating in designing and building a model ship/boatExplain addition to IED curriculum (first semester projects didn’t include good integrated unit possibilities)Doesn’t add much to IED sequence (can practice normal Inventor skills using this project, and a few days for building)
  • Describe importance of engineering in marine environment as a fieldAcknowledge some schools aren’t near water, but marine engineering is still relevant
  • Review theme of each subunit
  • Review major academic topics covered in unit
  • Explain that introductory lesson always introduced the unit and is taught by PLTW teacher to frame the rest of the unit
  • Briefly describe man’s history of seafaring (long-standing)Use the next slides of various boats and ships to review the idea that boats come in many different shapes and sizes that are governed by their intended purpose and anticipated water environment
  • Introduceenglish connectionLiterature associated with sailing, etc, introduces and contextualizes the activity of ship design
  • One instructional strategy we suggest is Literature CircleAsk an English teacher to explain and then summarize (or refine/correct, if necessary)Review the possible roles
  • Explain that we will practice this strategy using excerpt from Life of Pi, one of the suggested readingsGive summary of book prior to excerpt: Pi is teenager, moving with family (and family business, zoo animals) from India to Canada. Near beginning of book, cargo ship they are sailing on sinks. Much of novel about Pi’s survival experience on lifeboat.Have them get into groups, assign roles, and read excerpt, and discuss in small groupsThen discuss as large group.
  • Move on to Social Studies connectionsWorld War II, many engineering innovations results from necessity in wartime
  • Give brief description of situation in Europe prior to invasion of NormandyPoint out primary sources in curriculum binder describing invasion analysis
  • Explain that Rommel was anticipating invasion and prepared defenses
  • Review each of the defensesHave participants use page 1-87 to brainstorm possible countermeasures to defenses
  • Share out brainstormed countermeasuresDescribe some of the actual innovations developed
  • Move on to Math/Science connection
  • Review this problem to make sure people know what’s going on and didn’t get lostVolume of submerged portion: 108 cm3Volume of total object: 120 cm3Possible dimensions: 4 cm x 5 cm x 6 cm
  • Last subunit focuses on designing and building a model. Also includes a geography lesson on waterways around the worldand in English student apply the earlier lessons to write a short story that takes place on their designed boat
  • Test modelsAsk for questions/comments
  • Next unit, reverse engineeringDescribe reverse engineering unit in IED
  • Ask participants to define reverse engineeringAsk for examples in real worldDefine and share actual examples
  • Review major academic content covered in unit
  • Move on to English connectionTechnical communication/writing is key in engineeringWhen communication is poor, a lot of things can go wrong
  • Review implementation considerations (see IED presentation)
  • Review changing/adding/removing lessons, etc
