1 2008 Annual ASEE Conference & Exposition BACKGROUND MISSION APPROACH RESULTS QUESTIONS iMELT: integrating Mathematics, Engineering, and Literacy in the Teaching of Mathematics Heath Tims, PhD Assistant Professor Mechanical Engineering Louisiana Tech University

2 2008 Annual ASEE Conference & Exposition BACKGROUND MISSION APPROACH RESULTS QUESTIONS Work conducted at the Louisiana Tech University Heath Tims Galen Turner Don Schillinger Brian Camp

4 2008 Annual ASEE Conference & Exposition BACKGROUND MISSION APPROACH RESULTS QUESTIONS we are failing to capture the interest of our youth for scientific and mathematical ideas. We are not instructing them to the level of competence they will need to live their lives and work at their jobs productively. Perhaps worst of all, we are not challenging their imaginations deeply enough. – John Glenn 1 National Science Boards Science and Engineering Indicators 2004: - enrollment in undergraduate engineering and science programs has been in decline since the 1980s - urges partnerships between universities and local schools to increase the mathematics and science abilities of high school graduates 1- foreword to the national report Before Its Too Late

5 2008 Annual ASEE Conference & Exposition BACKGROUND MISSION APPROACH RESULTS QUESTIONS Gaining Early Awareness and Readiness for Undergraduate Programs (GEAR UP) efforts focus on schools where more than 50% of the student population is eligible for free or reduced lunch. More than half of the students are failing to achieve basic levels of performance in state criterion-referenced tests in math. Contributing factors include: –More than 80% of students live in poverty as evidenced by eligibility for free or reduced-price lunch; –On average, students attending these schools have a one in three chance of being taught a core subject by a teacher who is not certified or is under qualified for the job; –Nearly 60% of 8 th grade students, and over 60% of 9 th grade students achieve below basic levels on state mandated tests in English/Language Arts

6 2008 Annual ASEE Conference & Exposition BACKGROUND MISSION APPROACH RESULTS QUESTIONS - improve student achievement in mathematics while strengthening literacy skills resulting in improved student achievement in English Language Arts iMELT integrates engineering applications and activities and aligns them with state curriculum requirements for mathematics. The target audience for iMELT focuses on teachers from state GEAR UP schools. MISSION:

7 2008 Annual ASEE Conference & Exposition BACKGROUND MISSION APPROACH RESULTS QUESTIONS Performance data from partner schools in our region, demonstrated difficulty in the following areas (listed in priority order); –Number and Number Relations, –Geometry, –Constructed Response, –Measurement, –and Patterns, Relations, and Functions. GEAR UP Student Performance Data:

8 2008 Annual ASEE Conference & Exposition BACKGROUND MISSION APPROACH RESULTS QUESTIONS An alternative to simply progressing through a series of exercises that derive from a scope and sequence chart is to expose students to the major features of a subject domain as they arise naturally in problem situations. Activities can be structured so that students are able to explore, explain, extend, and evaluate their progress. Ideas are best introduced when students see a need or a reason for their use – this helps them see relevant uses of knowledge to make sense of what they are learning. * To this end, participants had the opportunity to construct simple machines using KNex education kits in order to discover real- world connections with mathematics content of their classroom curriculum. * Bransford, J.D., Brown, A.L., & Cocking, R.R. (Eds.). (1999). How people learn: Brain, mind, experience, and school.

9 2008 Annual ASEE Conference & Exposition BACKGROUND MISSION APPROACH RESULTS QUESTIONS The 5 E Learning Cycle Model* of Instruction was used to guide curriculum development and day-to-day instructional activities. First-hand knowledge gained from new explorations are used when students are learning new concepts The 5-E model includes five learning experience components: –Engage –Explore –Explain –Elaborate –Evaluate Karplus, R., & Their, H.D.

11 2008 Annual ASEE Conference & Exposition BACKGROUND MISSION APPROACH RESULTS QUESTIONS Day 6: Levers and Fulcrums Day 7: Incline Planes Day 8: Pulleys, wheels and axles Day 9: Culminating Design Challenge Day 10: Analysis of Lessons, Testing Day 1: Free-form bridge building Day 2: Bridge design and testing Day 3: Bridge analysis and contest Day 4: Mechanical advantage Day 5: Ratios and Gears

12 2008 Annual ASEE Conference & Exposition BACKGROUND MISSION APPROACH RESULTS QUESTIONS Example: Design of a small KNex truss: - demonstrates basic statics and mechanics of materials concepts, such as: force, compression/tension, and loads. - provides for application of algebra, geometry, and trigonometry - demonstrates elementary concepts such as number relations, measurement, patterns, and functions Hands-on experimentation and active learning:

13 2008 Annual ASEE Conference & Exposition BACKGROUND MISSION APPROACH RESULTS QUESTIONS Each teacher is required to develop and incorporate curriculum that is appropriate to their specific grade and subject. Teachers utilize a 5 E approach to exposing the students to the material they develop. School Implementation

14 2008 Annual ASEE Conference & Exposition BACKGROUND MISSION APPROACH RESULTS QUESTIONS PD weekends apply the 5 E model to the teachers experience in developing and implementing the curriculum in the schools. The outcome of a PD weekend is that the teachers have adjusted and refined their curriculum by a careful evaluation of participants experiences. This allows the teachers to engage their students in a revised curriculum. Professional Development Weekends

15 2008 Annual ASEE Conference & Exposition BACKGROUND MISSION APPROACH RESULTS QUESTIONS Engage: What is the longest bridge you can make that will support a 100g load with minimal sagging or bending? Your team may use materials from a maximum of 1 KNex Introduction to Bridge Building set to build the bridge. Maximum time allowed: 30 minutes Once you have completed your bridges, take the required measurements and record your observations. Explore: Explain: List and explain your accepted and rejected ideas based upon mathematic and science principles. Elaborate: Engineering Talking Points and Topics for Discussion How do structural engineers solve the problem of keeping the bridge span structure rigid over long distances? Evaluate: Test the bridge to see how it performs Answer questions related to observations and mathematic content Sample School Curriculum

16 2008 Annual ASEE Conference & Exposition BACKGROUND MISSION APPROACH RESULTS QUESTIONS 19 teachers participated in the Summer Teacher Workshop. 18 participants completed both a pretest and a posttest PLAN math test. –14 participants increased their posttest score, –1 remained the same –3 decreased Note that 78% (14 of 18) participants increased their score PLAN Test Results – iMELT Participants Subject# QuestionsPre-testPost-test MeanSDMeanSD Math Teacher Pre/Post Test Results

17 2008 Annual ASEE Conference & Exposition BACKGROUND MISSION APPROACH RESULTS QUESTIONS The students were more engaged in the lesson than any other lessons I have taught. They liked and enjoyed the hands on activities. I feel that they got more out of this activity because they were more engaged. – High School Teacher Teacher Feedback The kits allowed the students to use a hands - on approach to learning…The students were able to meet the objectives for the lessons. The grade level expectations were also met with the student using the KNEX kits to solve real life problems. – Junior High School Teacher
