teachers agreed,the degree of learning was not reflected in the assessment scores. Furthermore, althougheducators felt that the curriculum had helped their students learn engineering design throughhands-on activities, student results did not show increases in learning of the Engineering DesignProcess. This suggests that more explicit instruction in science and programming content and theengineering design process may be required for deeper learning.IntroductionRobotics is a timely, relevant and exciting field that incorporates a very broad spectrum ofengineering, science, and information technology disciplines. Robotics curricula have beenwidely used in both formal classroom instruction and out-of-school contexts and at many gradelevels to engage

The WebQuest includes a teacher section that provides a script for thelesson for other teachers to use in their classrooms.Section 3: MethodologyParticipantsChildren from six sections of a sixth grade combined social studies/technology class participatedin this study. There were 18 to 25 students in each section of the class and 116 studentsparticipated overall.

However, when a white cardis placed on the belt, the sensor receives the reflected light and theRIS is programmed to reverse the motor for 1.5 seconds. Thus, thecard is thrown in the rear basket. The RIS was also used to study Newton's laws in a number ofexperiments (see a sample of a manual for one such experiment inAppendix A). The experiments include distance measurement(Figure 9), velocity measurement, acceleration measurement, valueof gravitation constant, spring constant, etc. A rotation sensorattached to one of the wheels of the robot is used for distancemeasurement. The RIS can be used to measure the area of a circle, a triangle ora shape made of right
commitment to studentassessment, and teacher and program accountability, the Kirkpatrick evaluation model provides arigorous way to address the complex demands of today’s professional development models.Successful teacher education initiatives create a set of experiences that encourage participatingteachers to become genuine "learners” in situations intended to model a proposed instructionalapproach.13,14 Like students, teachers must be actively involved in learning, with opportunities todiscuss, reflect upon, and try out instructional approaches. Positive, self-sustaining curricularchanges are most likely to occur when teacher learning takes place within a professionalcommunity that is nurtured and developed from with the school and beyond
) What are the Constraints of the challenge? (list) EXPANDED DESIGN CHALLENGE: Reword the design challenge to include the specifications and constraints. DESIGN PORTOFOLIO The design portfolio has several elements—challenge (including specifications and constraints), developing knowledge (knowledge and skill builder activities), creating alternative solutions (evaluating trade-‐offs and selecting the optimum solution), building and testing a prototype, evaluating the design and refining the design. There is also a reflection section and an extension section for students

guided discovery approach posits that any subject can be taught effectively in someintellectually honest form to any child at any stage of development. A constructivist approach tolearning and teaching is based on the notion that learners construct their own knowledge ratherthan knowledge being transferred into learners‟ brains.8-10 Learners‟ construction of knowledgeis based on their past knowledge, the timeliness of new knowledge, and the learner‟s ability tounderstand the connections. This process forces learners to either modify existing knowledge ordevelop new knowledge. Learning experiences based on constructivism are reflected in popularinstructional strategies such as inquiry based learning11-12, problem based learning (PBL) 13-14

and subtraction, the matrices should have the same dimensions in order to perform theoperation.b. FunctionsFunction Transformations In mathematics, there are several basic functions: f(x) = c, where c is a constant, f(x) = x,f(x) = x2, f(x) = x3, f(x) = |x|, f(x) = x . Various transformations or combination oftransformations can be performed on a basic function. Transformations can cause a shift, areflection, a stretch, or shrink of the original graph. For example, we can negate a function suchthat g(x) = -f(x), which will produce a reflection across the x-axis. We can have g(x) = f(-x),which will produce a reflection across the y-axis. We can modify the function such that g(x =f(x)+ c, which will shift the original graph up by c units

Many engineering programs that have beendeveloped over the last decade do not fit this model and still reflect a more traditional view ofengineering. Meeting the challenges cited by the NAE report requires multiple and diversepathways for students to come to engineering, including new and innovative alternatives to Page 25.484.3compliment the more traditional programs.One pathway that fits the characteristics described in the report from the National Academy isservice-learning.

First, PLTW in Iowa tends toattract white males and students who have higher achievement in mathematics and science injunior high. The percentages of women who enter PLTW are approximately the same percentagethat enters mechanical and electrical engineering programs (Walcerz, 2006). Overall, theselection bias was rather significant, with participants scoring between 0.72 and 0.9 standarddeviations higher on mathematics and science scores prior to entering PLTW. We stronglysuggest that future research on PLTW needs to reflect selection bias in their analysis of theprogram. We controlled for selection bias using propensity score matching that predicted entry

STE units were developed; the pre-pilot PD,teaching, and reflection cycle was completed; many materials were purchased for the pilot yearsfor all 3rd and 4th grade (and even some 1st and 2nd grade) pilot year classrooms; PD for the pilotyear for most 3rd and 4th grade teachers took place; and an educational video about the projectwas created. To summarize, beyond having Workforce One Maryland Program funds to pay forproject costs, there were six essential factors for the success of the HCPS-TU Partnership. ThisSySTEmic Project partnership had: 1. A co-constructed vision. 2. Access to high-quality EiE curriculum. 3. Team members with unique strengths and a shared language. 4. A collaborative spirit—an
quantity for length changed (a stick was eliminated) and a material (pipecleaner) was eliminated. The significant changes to the materials for length yielded a LengthRelationship Score of 1. However, the material intended for Key Acquisition (the stick)remained the same, which is why the Key Acquisition Relationship Score remained a “perfect”3. It should be emphasized that the Total Relationship Score was designed to reflect therelationship between the ideas in the drawing and the artifact. It does not reflect the quality ofthose ideas.

where they learn how to work with the students before they deliverthe research-inspired challenges they developed. The learning experience for the middle schoolstudents is also scaffolded by successively exposing them to more about the engineering designprocess and what they are expected to do in the subsequent sessions. During the delivery portionof the class there are no additional assignments beyond preparing the design challenges and theadditional class session each week is reserved for discussion and reflection in a learningcommunity setting.The final portion of the class is devoted to the reflection and to finalizing the documentation inlight of experiences at the middle school. The materials created during the class are valuable andworth
technology professionals at a variety of levels and in avariety of environmental fields1. This type of multidisciplinary, technology-based approach isnot sufficiently reflected in our current educational programs.The classroom integration of sensor development is therefore not only topical but offers highlyinterdisciplinary subject matter, providing motivating scenarios for teaching STEM topics andskill sets. SENSE IT provides students with the opportunity to learn about sensor technologythrough a hands-on, collaborative process of designing, constructing, programming and testingwater quality sensors. Design-based activities such as SENSE IT provide a rich context forlearning and lend themselves to sustained inquiry and revision. Application of
. By their nature, Fermi problems depend on the use of some prior knowledge. Studentsmust be able to perform the following steps: 1) conjure up relevant values such as theapproximate U.S. population or MPG of a car, 2) understand the necessary mathematicaloperations to perform on these values, 3) use those operations in a logical and cohesivemathematical way, and 4) reflect on whether the estimate might or might not be reasonable. Thekinds of problems presented by the 3D Estimator primarily assess students' performance of thethird step, thereby assisting with performance on the fourth. That is, the 3D Estimator assessesstudents' use of mathematical operations and numerical strategies for producing reasonableestimates. Producing reasonable

result in actually testing their ETK in a middle school class. When a middle schoolteacher feels the team is ready, they go into the classroom. The first version of each ETKis always taught by the team that developed it. They are accompanied by one or moreobservers, and the classroom teacher is present during the lessons. We ask each teacher toprovide comments and reactions on the use of the ETK in their class, and to suggest waysto improve it. We also ask whether any problems might arise in using the ETK. Finallywe want to know if the teacher feels he or she could use the ETK without our teampresent.Members of the design team also reflect on how they think the field test went. Based onall this feedback, the team prepares the next version of

that analyzed the influence of television on theresulting negative images that viewers (particularly white viewers) developed as relatedto various minority groups, including race, gender, and ethnicity. Once classic exampleof such an analysis is the study of the image of race (focusing on African-Americans)during the early days of television (the 1950s). MacDonald7 notes that blacks portrayedduring the 1950s were typically cast as inferior, lazy, dumb, and dishonest individuals.Negro doctors were presented as quacks; Negro lawyers were cast as unethical cowardswho did not understand their own profession. Even in the 1970s, it was noted that blackchildren had few positive role models on television8 . Reflecting more recent portrayals(mainly the
