Developing Children’s Proportional Reasoning: Instructional Strategies That Go the Distance

Proportional reasoning is one of four key areas of instruction for sixth and seventh grade mathematics as established by The Common Core State Standards for School Mathematics (CCSSM, 2010). This article describes the importance of proportional reasoning and provides educators with strategies that can be implemented in the classroom to help students develop their proportional reasoning

Adolescents\u27 Self-Described Transformations and Their Alignment with Transformative Learning Theory

This phenomenological, collaborative inquiry explored the depth of two adolescent girls’ lived experiences during their high school years and the degree to which their self-described transformative incidents aligned with transformative learning theory.Traditionally this theory has been reserved for adults, yet the current paradigm may have overlooked the capabilities of modern adolescents to not only experience, but to describe and interpret transformative learning in ways both similar to and unique from adults.My two 19-year-old co-researchers and I examined four years of their self-identified transformative incidents by breaking them into components, analyzing the language within, and seeking evidence of critical self-reflection throughout; and then compared the extent to which the incidents aligned with the frameworks of adult transformative learning theory.Findings indicate that the co-researchers did experience transformative learning as defined by several theorists and exhibited both adult-like capabilities of:critical self-reflection, rational discourse, and reflective action; and adolescent-like aspects of:the development of identity, self-authorship, and empathy.This study challenges current assumptions in the theory and adds to the holism of the field.This Dissertation is available in Open Access at AURA:Antioch University Repository and Archive, http://aura.antioch.edu and OhioLink ETD Center, http://www.ohiolink.edu/et

HI Clouds in the M81 Filament as Dark Matter Minihalos--A Phase-Space Mismatch

Cosmological galaxy formation models predict the existence of dark matter minihalos surrounding galaxies and in filaments connecting groups of galaxies. The more massive of these minihalos are predicted to host HI gas that should be detectable by current radio telescopes such as the GBT. We observed the region including the M81/M82 and NGC 2403 galaxy groups, searching for observational evidence of an HI component associated with dark matter halos within the "M81 Filament", using the Robert C. Byrd Green Bank Telescope (GBT). The map covers an 8.7 degree x 21.3 degree (480 kpc x 1.2 Mpc) region centered between the M81/M82 and NGC 2403 galaxy groups. Our observations cover a wide velocity range, from -890 to 1320 km/s, which spans much of the range predicted by cosmological N-body simulations for dark matter minihalo velocities. Our search is not complete in the velocity range -210 to 85 km/s, containing Galactic emission and the HVC Complex A. For an HI cloud at the distance of M81, with a size < 10 kpc, our average 5-sigma mass detection limit is 3.2 x 10^6 M_Sun, for a linewidth of 20 km/s. We compare our observations to two large cosmological N-body simulations and find that the simulation predicts a significantly greater number of detectable minihalos than are found in our observations, and that the simulated minihalos do not match the phase space of observed HI clouds. These results place strong constraints on the HI gas that can be associated with dark-matter halos. Our observations indicate that the majority of extragalactic HI clouds with a mass greater than 10^6 M_Sun are likely to be generated through tidal stripping caused by galaxy interactions.Comment: 15 pages, 7 figures.

Everything You Need to Know about Grants: Beginning, Middle and End

“Everything You Need to Know about Grants: Beginning, Middle and End” was a 90-minute session presented at the Society of California Archivists Annual General Meeting in Berkeley, CA, on April 13, 2013. As a part of the archival community, many of us know that grants are an excellent way to reduce backlogs or accomplish projects we don\u27t have the resources to tackle. However, what many of us may not know is how much work goes into successfully implementing and completing a grant. The purpose of this session was to assemble a group of individuals who have been involved in various aspects of the grant application and implementation process to share their expertise with the archival community. The session utilized a question and answer format with a moderator asking pre-arranged questions. This article provides excerpts from the panelists’ responses

Hagie Ideal Welding Cell

Hagie Manufacturing is a company based in Clarion, Iowa, where they build sprayers for agricultural applications. There are around 140 employees currently working at Hagie, and they are ranked in 2nd among their other top 10 competitors. Hagie has an impact in Iowa by being known as a locally established company, created by a friendly farmer that wanted to have personal and family-oriented business to support his neighboring farmers. Welding production requires an increase to 2 machines per day in order to stay up with demand. Hagie has full capability to keep up with John Deere’s standards, which have been set by a business deal in early 2016 between the companies. Hagie is struggling with the flow of their boom arms in their weld cell, and they also have areas for organization and ergonomic improvements. Costs could include line downtime while changing the layout of the cell, moving workers to other areas, hiring new workers, and implementing new machines and fixtures. Risks could include not keeping up with current takt time after making changes to the process, or greatly improving their task time. Working on these improvements fosters the business relationship Hagie now has with John Deere, and the network they will be expanding into. Many other companies, especially small family established businesses like Hagie, are working on solving the same types of problems. Some ended up growing too fast, which made the organization difficult to be prepared for mass production. The solution could be used in other situations, but it would be particular to the space Hagie has to build the boom arms. The ideas used in breaking up the process and movement of parts could assist other companies in understanding how to create better flow in their facilities. Many aspects of life could use an assessment of process layout and movement, everything from manufacturing, to healthcare, could benefit from using these tools
