A long-term study of educational robotics and achievement in math and science

In recent years, educational robotics has become a popular tool in STEM programs, such as afterschool clubs, and summer camps, as well as classrooms. However, the research on the benefits of robotics have shown mixed results. In addition, many of the studies lack strong controls and focus on short-term effects, while the programs they investigate have few contact hours and do not have a consistent curriculum. This situation indicates that more research is needed. This work focuses on a public high school in Texas with a year-long robotics class. The first part examines a set of students who enrolled in the robotics class in the 9th or 10th grade, and a comparison group of students who did not enroll in robotics. The robotics and comparison groups were matched on 8th grade standardized math test scores, and demographic factors. Using multiple linear regression and logistic regression, I found that robotics enrollment was not a significant predictor for 11th grade math standardized test scores, or high school enrollment in Physics 1, Physics 2, or Calculus classes. The second part examines a series of video recordings of student teams in the robotics class working on a capstone project. Using grounded theory, I coded and analyzed recordings of two of the teams, focusing on the math and science discussions between the students and the contexts in which the math and science occur. Three themes emerged from the data. First, students use math/science more frequently to identify and fix problems than in their initial design. Second, students use math/science at a conceptual level and do not perform math calculations. Last, students have a “good enough” attitude and do not prioritize precision. These results may help explain the lack of effect robotics have on math test scores.Science, Technology, Engineering, and Mathematics Educatio

Changes in Teachers’ Adaptive Expertise in an Engineering Professional Development Course

Although the consensus seems to be that high-school-level introductory engineering courses should focus on design, this creates a problem for teacher training. Traditionally, math and science teachers are trained to teach and assess factual knowledge and closed-ended problemsolving techniques specific to a particular discipline, which is unsuited for teaching design skills for open-ended problems that may involve multiple engineering disciplines. Instead, engineering teacher training should use the more fluid framework of adaptive expertise which values the ability to apply knowledge in innovative ways as well as recall facts and solve problems using conventional techniques. In this study, we examined a 6-week program to train math/science teachers to teach high school design engineering. For each curriculum unit, we had a pre-posttest to assess the teachers’ factual knowledge and ability to solve typical problems (termed ‘‘efficiency’’) and their ability to apply their knowledge to reason through open-ended problems (termed ‘‘innovation’’). In addition, we conducted a pre-posttest to see whether teachers’ attitudes and beliefs related to adaptive expertise changed over the course of the program

Get screened: a pragmatic randomized controlled trial to increase mammography and colorectal cancer screening in a large, safety net practice

Abstract Background Most randomized controlled trials of interventions designed to promote cancer screening, particularly those targeting poor and minority patients, enroll selected patients. Relatively little is known about the benefits of these interventions among unselected patients. Methods/Design "Get Screened" is an American Cancer Society-sponsored randomized controlled trial designed to promote mammography and colorectal cancer screening in a primary care practice serving low-income patients. Eligible patients who are past due for mammography or colorectal cancer screening are entered into a tracking registry and randomly assigned to early or delayed intervention. This 6-month intervention is multimodal, involving patient prompts, clinician prompts, and outreach. At the time of the patient visit, eligible patients receive a low-literacy patient education tool. At the same time, clinicians receive a prompt to remind them to order the test and, when appropriate, a tool designed to simplify colorectal cancer screening decision-making. Patient outreach consists of personalized letters, automated telephone reminders, assistance with scheduling, and linkage of uninsured patients to the local National Breast and Cervical Cancer Early Detection program. Interventions are repeated for patients who fail to respond to early interventions. We will compare rates of screening between randomized groups, as well as planned secondary analyses of minority patients and uninsured patients. Data from the pilot phase show that this multimodal intervention triples rates of cancer screening (adjusted odds ratio 3.63; 95% CI 2.35 - 5.61). Discussion This study protocol is designed to assess a multimodal approach to promotion of breast and colorectal cancer screening among underserved patients. We hypothesize that a multimodal approach will significantly improve cancer screening rates.

Reinterpretation of LHC Results for New Physics: Status and recommendations after Run 2

We report on the status of efforts to improve the reinterpretation of searches and measurements at the LHC in terms of models for new physics, in the context of the LHC Reinterpretation Forum. We detail current experimental offerings in direct searches for new particles, measurements, technical implementations and Open Data, and provide a set of recommendations for further improving the presentation of LHC results in order to better enable reinterpretation in the future. We also provide a brief description of existing software reinterpretation frameworks and recent global analyses of new physics that make use of the current data

Student Learning in Challenge-Based Engineering Curricula

In recent years, there has been a demand to teach engineering in high schools, particularly using a challenge-based curriculum. Many of these programs have the dual goals of teaching students the engineering design process (EDP), and teaching to deepen their understanding and ability to apply science and math concepts. Using both quantitative and qualitative methods, this study examines whether a high school design engineering program accomplishes each of the two goals. During the 2010–2011 school year, over 100 students enrolled in the same design engineering course in seven high schools. Evidence of learning and application of the EDP is accomplished by triangulating student interviews with pre-/post-tests of EDP-related questions and a survey of design engineering beliefs. To determine whether students could apply science and math concepts, we examined content test questions to see if students used science and math ideas to justify their engineering work, and triangulated these results with student interviews. The results are mixed, implying that although there is some learning, application is inconsistent
