and problem solving concepts.This paper will describe the twelve week experience of a home schooled group engaged in theTWT program. Home schooling is a growing trend in the United States and it is estimated thattwo million American children are home schooled each year with this number increasing by 15-20% per year1. The students’ progress in this program was measured through specific reflectionquestions, as well as observations and reflections by the TWT facilitators and the cooperatinghome school representative and the parents of the home schooled students.The Toying With TechnologySM ProgramThe Toying With TechnologySM Program at Iowa State University has been reported on manytimes in the literature2-7. This program includes an

One survey askedparticipants to rate their agreement with various statements related to program content andadministration at the end of the program using a Likert scale (responses included “stronglyagree” (5), “agree somewhat” (4), “not sure” (3), “disagree somewhat”(2), “stronglydisagree”(1)). The other survey queried participants on how well their expectations wereachieved during the program, and asked participants to rate each statement in terms of the extentto which each factor was reflected in their summer experience (a score of 1 indicated that it wasnot at
provide students with personalized tutors through the use of educational software.However, without the authoritative involvement of a teacher, many students are not motivated tolearn material presented via computer. The challenge to educational software designers is tocreate environments that motivate students to think reflectively about content, encouraging themto invest time and energy in the learning process. One manner in which to accomplish this goalmay be to include student ideas when developing software. This paper presents the results of aresearch investigation that examined the inclusion of middle school students in the process ofdesigning educational software. Eight middle school students participated in a focus groupdiscussion, during
operating systems were discussed, includingWindows 98, Windows 2000, and Windows XP. File management, virus protection, andbackup were also discussed. A hands-on lab exercise on configuring an operating systemwas performed.The final course topics were Basic AC Quantities, followed by Light Propagation, Snell’sLaw, and the Critical Angle of Reflection. These modules covered some of the contentfield of Applied Mathematics by using algebra, geometry, and trigonometry to solvetechnical problems. In addition, the content field of Science/Technology was introducedwith the discussions of fiber optics and light propagation.

In brief, the humancortical brain can be

It is interesting to note that three of the most important Page 11.762.7things learned by the public school students who participated were:1. Engineering is a very intellectually demanding process.2
Sensors in High School Living Environment Labs: A GK-12 Project1. Introduction In a series of recent op-ed pieces in The New York Times and in his latest book The WorldIs Flat,1 Thomas Friedman points to an urgent need to develop a strong and technologicallytrained workforce to ensure the American leadership in scientific discovery and technologicalinnovation. This call to action has been joined by business and government advisory groups suchas the American Electronics Association,2 the National Innovation Initiative,3 and the NationalAcademy of Engineering;4 and reflected in the remarks delivered by industry captains such asBill Gates at the 2005 National Education Summit on High Schools.5 In a recent letter6 to

The Board of Directors expressed theirdelight with the improved attendance and format of the YESS program and asked the co-leadersof the 2004 YESS program to lead the 2005 YESS program again with this revised hand-onapproach. A full description of the 2004 YESS program was highlighted in the HistoricalElectronics Museum, Reflections newsletter5.The 2005 program was similar to the 2004 program and was designed to have the high schoolstudents learn how to go from brainstorming to designing, building, and testing. The over-arching project, performed in teams, was to design a mousetrap vehicle which had to meetvarious design criteria, which include maximizing distance traveled, pulling capability, speedover a
, demonstrations, laboratory exercises, individual andgroup projects, and field experiences to: 1) enable high school students to directlyexperience authentic learning practices that require them to use higher-order thinkingskills; 2) encourage creative problem-solving skills that require collaborative learning,teamwork, writing, and presentation; 3) cultivate an interest in service learning, in whichstudents are active participants, achieve outcomes that show a perceptible impact, andengage in evaluative reflection; and 4) better motivate and prepare secondary schoolstudents for advanced education. The Fellows have been and continue to be trained tocreate and implement these activities.Through the course of each year, the Fellows complete a specially

This activity demonstrates that targets moving towardthe wave sources reflect things at a higher frequency than targets moving away from thewave source. Blinded observers are asked to guess if the pan is moving up or downbased on the frequency of the drip sounds created.Standards MetThis curriculum meets numerous National Science Education Content Standards(A,B,C,E,F,G). Students are provided with an opportunity to do scientific inquirythrough the challenge based curriculum
minutes to two hour) laboratory exercises toexpose them to a variety of science content areas. One of the lab periods was used toexplore Oklahoma agriculture in the classroom activities2. A lab notebook was due atthe end of the semester that included self reflection on the science content of theexercises and the appropriate grade level.The majority of the second half of the semester was devoted to science module trainingand teaching. The students were trained in science modules for grades 1-5 at theOklahoma State University Center for Science Literacy3. During the module training, thestudents were taught how to keep laboratory notebooks. The science modules used weredeveloped by the National Science Resources Center (NSRC) that is operated by
questions addressing DET.Next, a group of education and engineering faculty reviewed the survey items and identified theitems that best reflected the information being sought. A hard copy of the second draft of thesurvey was then created and field tested with a focus group of five teachers who helped refinethe wording and added or eliminated items. These teachers were given an honorarium for theirparticipation. A final electronic version of the survey was placed on a website that allowedteachers to respond to the survey via internet. The final version of the survey included 69 items,each with a four-point response format ranging from one to four. Sixty-five of the survey itemswere to be answered by teachers at all grade levels. The last four items

Our goals includeusing cutting-edge research to engage and inspire pre-college students to becomeinterested in science and engineering, particularly nanoscience and nanotechnology.Background and ApproachTraditionally, we think of “looking” at something small with a light microscope. In fact,the size of objects resolved with a light microscope is limited by diffraction to roughly200 nm. Hence, we cannot see nano-objects because the wavelength of the visible light issimply too large to be reflected off of them. So another “touch” based

Instructors worked with all participants untilthey could perform each skill well.. Each week they also learned background theory. Among theexperiments were ones on lenses and image formation, polarization, reflection and refraction,spectral dispersion and bandwidth, spatial filtering and beam expansion, and analog and digitaloscilloscopes. The groups made their own holograms and were allowed to keep them. Theywere able to see the difference between s and p-type polarization, to understand why polarizedsunglasses work, and they saw a high-power laser demonstration that included a discussion ofwhich lasers work the best
achievement and student attitude iswell documented.[28-31] Likewise, student attitudes toward a subject will be reflected by theirinterest levels in the classroom. If we are to believe that students learn more when they areinterested in the material, then a measure of student attitude should provide insight into thepotential for enhancing student achievement or competency.Attempts to quantify improvements in student attitudes toward STEM by analyzing the pre/postprogram “I Like Math” attitude surveys have been marginally successful. The data haveprovided sporadic results which largely consist of a smattering of positive and negative findings,none of which represent any real or consistent trend. In fact, looking at the bigger picture, wehave seen that

In any change of the curriculum it is important to use what isknown about individual differences of the students to determine for whom any particularinstructional method is appropriate and for whom it is not appropriate.6
written science education frameworks that guide theirscience programs in grades K-12. Many use the Benchmarks, NSES [3] or both as the guidingframework for science content often reflecting this content through the traditional sciencedisciplines, e.g. earth science, biology, chemistry and physics. As demonstrated in this brief Page 11.229.4expose, Benchmarks [2] and NSES [3] recommend the blend of technology into the scienceframeworks as a means to promote scientific literacy. As science educators develop and revisetheir science curriculums, the inclusion of technology and engineering concepts, asrecommended by these documents, would augment their

Assessment instrumentsincluded beginning, middle, and end-of-design experience questionnaires, videotapes of studentpresentations, and a reflective letter to their parents. Through the data collected, the paperanswers the following questions: a) Are real-life student design projects an effective means ofintegrating different courses? b) Did the real-life student design projects provide better studentunderstanding of engineering in general? c) Did the exercise of designing and presentingprojects, stimulate student interest in science and engineering careers? This pilot assessmentplan will be used to improve the program as well as to assess student learning

Further, when Page 11.587.3students are encouraged to create artifacts (Appleton, 2000), they both reflect and enhancestudent understanding.The particular design strategy used was based on the informed design cycle (Burghardt andHacker, 2003). It is iterative and allows, even encourages, users to revisit earlier assumptionsand findings as they proceed. Figure 1 shows the overall cycle. A key differentiating factor inthe informed design process is in the Research and Investigation phase. The use of Knowledgeand Skill Builders (KSBs) provides structured research in key ideas that underpin the designsolution
questions • Learners evaluate their explanations in light of alternative explanations, particularly reflecting scientific understanding • Learners communicate and justify their proposed explanations. Research also suggests that the quality of the teaching workforce is the single mostimportant factor in predicting student achievement.15 Robert Marzano has conducted anextensive review of the research studies involving factors that impact student achievement andconducted meta-analyses of those studies to determine the effect size of the factors on studentachievement16. He describes three types of factors that impact student achievement: school-level factors, student-level factors and teacher-level factors. What factors can SWEPT/RETs

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
. Changes were not seen regarding student intent to study at a 4-year college vs. acommunity college, nor were there changes in the intent of students to study bioengineering atour university or any other. For the former, we naively presumed passive exposure to theuniversity environment would cause some changes in these areas. However, the mean of 9.53for this question in CY2 suggests that this was not an area that needed improvement. At anyrate, without actively addressing these issues via lectures or laboratory sessions, no significantchanges in these attitudes were recorded. Interestingly, the means for post-camp CY2 andCY3 were very similar overall, likely reflecting a consistent pool of students. For instance,the highest mean of 9.53 in CY2

I'm also never fully sure how my time away is seen by my superiors. Do they view it as slacking off or helping

Sixty-six percent of participants were male, and most came from private schools orthose in wealthier districts. Anecdotally, they were also primarily Caucasian. In subsequentyears, gender equity recruitment protocols were implemented and refined so that now theparticipant population appropriately reflects the gender, socio-economic and ethnic diversity ofthe community

Unfortunately, thedemographics of US students earning engineering degrees and those practicing as professionalengineers do not reflect the US population1. Among the
School of Engineeringand Applied Science. Initially, the MITE program was intended to serve as a preparation andrecruitment program for first-generation college students and minority groups in engineering,defined as: women, African-Americans, Hispanics and Native Americans. In 2002, the programwas renamed the Introduction to Engineering, reflecting a conscious decision to make theprogram more overtly inclusive of all demographic groups. The OMP continued to run theprogram and was officially renamed the Center for Diversity in Engineering (CDE) in 2004. Inaddition, in 2003, a new emphasis on hands-on engineering was introduced and material frominteractive engineering teaching kits was incorporated into the ITE program. This included theadoption
mathematical simulations. The authors speculate that thisdecrease may reflect a new appreciation for the complexity of engineering design and a healthyreassessment of their expertise after exposure to the curriculum unit. Similar decreases inconfidence in math have been reported in the literature.5 Close attention will be paid to whetherthis trend persists in future trials and modification will be made to the module as necessary toaddress this issue. Finally, students also took a Post Module Questionnaire at the completion of thecurriculum unit. This questionnaire was broken into two sections. The first section askedstudents to indicate whether their interest or skills in certain areas increased, decreased orremained the same as compared to
assignments, the separateyears depicted in this figure are cross-sectional, and should not be interpreted longitudinally.What is particularly striking is the central role played by the Fellows in facilitating therelationship between the Westlake and Georgia Tech communities. Despite recruiting newFellows and professor-mentors each year, the structure and size of the Fellow social networks isremarkably consistent. The increasing size over time of the complete Westlake-Georgia Technetwork is not reflected in the egonet of the STEP Fellows.Mathematical AnalysesEach of the social networks depicted in the Figures is based on person-by-person and person-by-activity matrices. These same matrices can also be analyzed for aggregate characteristics of
-world challenges and problems, and the utilization of theseproblems to help students understand and appreciate the work which scientists and engineers do.In reality, the NSWCDD mentors play three roles: they serve as exemplary individuals workingin a Navy setting, colleagues working with the teachers in the classroom, and role models andmentors to the students. Since the community as a whole (students, parents, teachers, schoolsystem, and employers) is invested in the program, such mentoring programs are more effectivethan if only a school-based program was implemented. See Nation et al (2005)9.Anecdotal comments, reflecting indirectly on the role of the mentors, support the quantitativeindications (see next section) of the success of the
