pattern is discovered, the next step is the generalization and abstraction of the pattern.The skill encompasses the ability to filter information to solve a problem and re-defining it ingeneral terms using variables and/or formulas so problems that are similar in nature can besolved in the same way. For the example shown above (the sequence of numbers) the patterngeneralization and abstraction step comprises taking the sequence and converting it into arecurrence relation. The formula that abstracts the sequence can be written as S(i) = S(i-1) + 3 *i where i is a positive integer and S(0) = 1.D.

Engineeringstandards were not part of the new district standards, yet our experience was that some teachers,particularly cohorts from the same schools, continued to be enthusiastic about teachingengineering and considered it important. The purpose of this study is to explore one suchelementary school’s experience in implementing engineering and the resulting student outcomes.A case study research method is used to illuminate a specific decision or set of decisions throughanswering why the decision(s) were taken, how they were implemented, and with what resulted.4 Page 23.474.2While the final

We discuss implications for therecruitment of future participants for engineering-based curriculum interventions, and weconsider the sustainability of such interventions after the completion of formal researchprograms. Finally, we suggest directions for future research on the changes over time inteacher characteristics and perceptions when they participate in K-12 engineeringprograms.Previous ResearchStudies since the 1950’s have attempted to capture exactly what teacher characteristicshave the most impact on student learning,6 but despite a multitude of research

The purpose of this paperis to present how interest relates to engineering as a career choice for a group historicallyunderrepresented in engineering. Using the Social Cognitive Career Theory as a frame work,high school and college engineering students from Appalachia were interviewed concerningcareer choices to answer the research questions: What role(s) does interest play in engineeringcareer choices of Appalachian students? How do such roles differ for high school and collegestudents? To answer the research questions, qualitative data from a total of 36 junior and seniorhigh

14.1204.5 ≠ Design a Shoe ≠ Survival! ≠ Catapult ≠ Rainforest ≠ Toy Vehicle ≠ Bridges ≠ GreenhousesResearch Study MethodologyThe participants were 80 teachers that agreed to participate in the study. The majority ofparticipants were female (n = 64). 57 teachers reported teaching primarily at the middle schoollevel, and 23 were high school teachers. The teachers represented five content areas:mathematics (n = 20), science (n = 16), language arts (n = 17), social studies (n = 13), andtechnology or library media (n = 14). 67 participants were White, 11 – American Indian, and two– Asian. Most of the participants were in their early 40’s (βX = 39, M = 41).Participants were asked to complete a web-based version of the
the qualities of engineers for both males and females. A positive finding isthat many students indicated that they would like to know more about engineering.AcknowledgementsThis material is based upon work supported by National Science Foundation Award 0440568.References1.

Reliability was demonstrated using Cronbach`s alpha in order to determine the internalconsistencies of the used satisfaction scales, Cronbach alpha values above 0.9 indicate excellentreliability 14 and in this study it was found to be 0.958 for control group and 0.968 forexperimental one indicating excellent scales showing high internal consistency. Validity was also demonstrated through conclusion validity which is described asappropriateness of the conclusions reported based on statistical relationships 15, thus within thisanalysis conclusion validity was reported through the use of inferential statistics relying onstatistical significance results at the 5% threshold.Survey

through the use of LEGO-based engineering robotics. The motivation forthis study was derived from Schunn‟s work but is different in that the measurement ofproportional reasoning was purposefully planned and included a sample size of thirty students,including a control group.Norton (2006) used a LEGO-robotics context to investigate the mathematics learning of 46seventh grade students. He found that (a) the LEGO-robotics activities afforded learningopportunities that also reinforced social relationships, (b) explicit scaffolding was needed bysome students to achieve the mathematics learning, and (c) many students were able todemonstrate greater than expected mathematics and science learning.

. Historical and current data indicate that the need for science and engineering careers isincreasing, yet the number of students choosing and completing traditional science degrees isdecreasing. The decrease in students choosing and/or being qualified to enter science andengineering fields is continuing even with the programs geared towards increasing awarenessand preparedness. The gap between students entering science and engineering (S&E) fields andgraduating to meet the S&E employment needs was first noted in the early 1990’s. Manyresearchers suggested that recruitment and retention into the qualitative science fields shouldinclude women and minorities to assist in filling in the employment gap. Since a large numberof women and minorities
are students in transition.1 In this developmental phase of continuedbrain development and grand physiological changes, middle schoolers also begin dramaticchanges in their school structure, responsibilities, and social relationships. By the time theyreach middle school, students have already begun to develop dispositions toward mathematics,science, and engineering.2-4 By ninth grade, these dispositions are solidified and it becomes moredifficult to change the students’ feelings toward STEM careers.2 In this period of earlyadolescence, students either begin to develop strong academic habits or they begin to struggleacademically.3 “Middle grade[s] students are drawn toward mathematics if they find bothchallenge and support in their mathematics
