MSCC Advanced Manufacturing Curriculum Guide – Secondary Level 128 APPENDIX A ADVANCED MANUFACTURING ASSESSMENT GUIDE & ASSESSMENT TOOLS MSCC Advanced Manufacturing Curriculum Guide – Secondary Level 129 ADVANCED MANUFACTURING PERFORMANCE-BASED ASSESSMENT GUIDE Performance-based Assessment While standardized tests are the hallmark of public school assessment, because they are inexpensive and easy to administer, they are less than a perfect fit for a course like this one. While standardized tests are effective at measuring factual and contextual knowledge, they are largely ineffective in measuring students' skills or ability to apply concepts. Performance-based assessment techniques provide the teacher with a better tool for measuring both student understanding and ability. Performance-based assessments allow for the student to be evaluated against a set of previously identified criteria while performing a task reflective of the intended learning. Performance-based assessment provides the teacher with information about how a student understands and whether the student can apply the newly gained knowledge. These assessments are often used to evaluate student application, performance, values, skills, and abilities against a given criteria. By their nature, performance-based assessments require the student to use higher-order thinking skills than do traditional standardized tests. Performance-based assessment is best suited for measuring student cognitive application and psychomotor ability. For example, performance-based assessment is very well suited for use during oral presentations, while working as a member of a team, while operating a piece of equipment, or while defending an action. How is student performance measured? Student performance is best measured using performance criteria. By creating performance criteria upfront (prior to the test) and sharing that information early, students understand exactly what will be expected of them on the performance Advanced Manufacturing Curriculum Guide – Secondary Level 130 MSCC test. Additionally, these criteria allow the instructor and student to evaluate the task as objectively as possible. The measure of well-designed performance criteria is criteria that would allow a substitute instructor to evaluate the student performance as accurately as the person who developed the performance criteria. Four tools for performance-based assessment: o Rubric: A rubric is a rating scale that shows to what degree a criterion is met. Most rubrics use a three to five column scale that allows the teacher to indicate whether the criteria were "not met" to “superior." o Checklist: A checklist is a simpler version of a rubric and usually documents only whether or not certain criteria were met during the task. o Portfolio: A portfolio is a graphic record of projects and activities completed by the student over a given period of time that illustrates how well a student has met the performance criteria. o Project: A project is a tangible item that can be assessed based on performance criteria established at the beginning of the project assignment.

However, knowing all that we do about the best way to help people learn, your role as an instructor is more like that of a facilitator. You are there to direct and guide; to help learners question and interpret. Some of the responsibilities of instructors when facilitating are as follows: o Provide the foundation for learning experiences. Instructors are responsible for setting up learning activities, providing learners with objectives, and then encouraging learners to explore and learn; o Being a resource for learners. By helping learners find answers for themselves and directing them to information sources, facilitators encourage learners to become more autonomous learners – and less reliant on instructors; o Maintain a safe environment in which learners can experiment; o Lead discussions. Helping learners attain their goals without telling them the answers. By asking a learner to demonstrate a skill or state a principle, the facilitator is encouraging the learner to synthesize his own understanding and share that knowledge with their peers. Some questions that instructors might use to enable learners to express their ideas and reactions are: o "Are you saying that...?" (Asking about the learner's reasons) o "Why do you think…?" (Asking about the validity of the learner's statements) o "Couldn't it be right that...?" (Asking for supportive evidence) o "How do you know that ...?" (Asking for supportive evidence) o "How might we find out whether...?" (Asking for alternative possibilities) o Ask questions. Believe it or not, this is one of the most difficult skills for instructors to develop. It takes a great deal of planning and effort to MSCC Advanced Manufacturing Curriculum Guide – Secondary Level 146 master the skill of questioning. Here are some strategies that many instructors have found helpful: o When conducting a demonstration or discussion, prepare several key questions to get things rolling. This will also help assure that key points will be addressed; o Ask open-ended questions; avoid those that can be answered with "yes" or "no;" o Ask questions that require learners to think critically to explain their observations and draw conclusions. For example, in addition to asking recall questions (e.g., "How many bulbs lit up with one battery?"), ask learners to explain what they have observed (e.g., "Why is there a limit to the number of bulbs that will light up with one battery?"); synthesize what they have learned (e.g., "What can you generalize about all circuits?"); develop predictions based on what they understand to be true (e.g., "What would you predict will happen when more batteries are used?"); and apply what they have learned to other situations (e.g., "When planning electrical circuitry for a new building, what do engineers need to consider?"); o Sometimes try answering a learner's question with a question. This causes learners to think more critically and to solve problems on their own (or with other classmates); o After asking individual or groups of learners a question, allow 5-10 seconds of wait time before talking, providing a hint, or calling on someone. This allows all learners to respond – even those who may be unsure of themselves and those who prefer to think answers through before talking about them. MSCC Advanced Manufacturing Curriculum Guide – Secondary Level 147 SOLVING DESIGN PROBLEMS: STUDENT STRATEGIES To solve manufacturing design problems, students should employ the engineering “Design Loop.” The design loop provides a number of tools that assist individuals or teams as they try to create solutions. Try the following steps: 1. Analyze and Clarify the Design Problem: Carefully analyze the design problem and break it into its smallest systems and subsystems. Clarify the problem to determine exactly what you have been asked to create; 2. Conduct Research: Determine how others have solved similar problems in the past. Ask yourself if any of these solutions would be appropriate or could be adapted to solve this design problem; 3. Formulate or Brainstorm: Create as many possible solutions to the design problem as possible before attempting to implement any of them. For example, if the problem involved your inability to cross a body of water, some possible solutions might include a pole vault system, a boat, a hot air balloon, a catapult, or swimming (don’t lock yourself in to one line of thinking). Instructors should require students to produce several potential solutions prior to allowing the students to implement one of the solutions (See Design Brainstorming Worksheet in Appendix). 4. Question the Solution: Design teams should ask as many of the spur questions (below) as apply to the problem. By answering these questions, the team will add clarity to the proposed solution. The spur questions are as follows: o Is there another way to solve this problem or use these materials? o Can I borrow or adapt previous solutions or technologies? o Can I add a new element or twist that might lead to a solution? o Can I add more to the problem in an effort to find a solution? o Can I remove parts of the problem in an effort to solve it? MSCC Advanced Manufacturing Curriculum Guide – Secondary Level 148 o Can I incorporate substitutes or use other materials/technologies? o Can I rearrange the elements of the problem to find the solution? o Can I do the opposite of what I am currently thinking? o Can I combine elements or technologies to solve the problem? 5. Envision the Solution: Teams should make sketches and drawings of the proposed solution. By crafting these drawings, teams will add clarity to the final solution prior to implementing the solution. 6. Create: Select the most logical solution (often the simplest) and implement it (build it). This may involve creating a model, a rapid prototype, or a mock-up. 7. Evaluate the Solution: Test the solution and determine whether it indeed solves the problem. If it does not solve the problem, find out why and make changes. MSCC Advanced Manufacturing Curriculum Guide – Secondary Level 149 STRATEGIES TO IMPROVE STUDENT TEAM PROJECTS Many instructors are beginning to use team-based assignments as a major learning tool in school. One advantage of this instructional strategy is that it helps students to develop the social skills and abilities needed in today’s manufacturing industries. It also promotes independent thinking, collaboration, and problemsolving skills. Any instructor who has used team-based assignments in the classroom or laboratory knows that these assignments can be difficult to manage or evaluation. To overcome these potential problems, I suggest the following guidelines for team-based activity: 1. Generate Commitment: In many cases, the problems that occur during teambased activity can be traced to the lack of student commitment to the project. To generate commitment, try some of the following techniques: o At the beginning of the course, ask students to write down some manufacturing topics that they would like to work on during the course and then tie all team-based activities back to this list; o Use a similar technique to identify specific student interest areas and make team assignments based on that interest. For example, students particularly interested in PLC’s or rapid prototyping could be grouped together on a team; 2. Teach the Teams to Manage: Another reason teams fail is that they do not know how to manage the affairs of a team. In short, they do not innately know how to use time wisely or how to divide tasks equitably. To develop these skills, spend time after the design activity has been assigned assisting the teams as they organize for the task. Specifically, ask the students to: o Elect a Team leader who is responsible for keeping the team moving; o List their respective skills and talents; MSCC Advanced Manufacturing Curriculum Guide – Secondary Level 150 o Identify majors tasks to be accomplished; o Establish a timeline, reporting times, meeting times, etc.; o Divide the labor that needs to be accomplished; 3. Trust Students to Manage Groups: Team conflicts can arise during activities and these can be consuming a great deal of time. One effective solution is to encourage students to manage their own team. If, for instance, a student is not completing their tasks because they are not attending school everyday, inform the remaining team members that they should make decisions about whether that person should remain on the team. If they elect to remove that student from the team, they must make certain that they have documented the student’s negligence of duties, and inform the student of their decision. 4. Involve Students in Grading: Grading team work can be a problem because students are accustomed to being graded as individuals. To overcome this problem, use the Team Performance Rubric (Appendix II) to evaluate both individual and group accomplishment. This rubric should be provided to the teams on the first day of the assignment and teams should be asked to review the evaluation criteria paying special attention to the fact that they will be evaluated both on individual performance and team function. In conclusion, effective team-based projects build both knowledge and social skills. They also mirror in many respects the ways in which team function in the manufacturing environment. Seldom are managers excessively involved in micromanagement of workers, and workers are commonly involved (formally and informally) in the evaluation of each other. So, team-based learning help prepare the students for the workplace of the twenty-first century. Advanced Manufacturing Curriculum Guide – Secondary Level 151 MSCC Module #6: Team Building Instructional Guide Create Your Own Team Building Activity Directions: Use the following steps to design your own team-building activity. Challenging exercise best presented late in a program Divide a larger group into smaller groups of 4 to 5 Give groups ~15-20 minutes to come up with a challenging small group activity. The catch: The activity should be one that the group believes it can do better than any other group! Then all groups come together and take turns to present their activity. Groups earn points if: o No other group can beat them at their activity (+2) o Can do another group's activity (+1) Be warned: This is harder than it sounds - requires all elements of team work including creativity, communication, trust, problem-solving, time management, etc. To help groups succeed, the facilitator checks in with the progress during planning. Help with ideas or problem-solving strategies if the group is struggling. Encourage creative out-of-the-box thinking e.g., singing, dancing, joketelling, non-verbal, as well as physical or mental-type challenges. Avoid using this activity to get out of designing an activity yourself!
