Mathematics Online Assessment Tools

This paper explores which online assessment tool is preferred within a classroom setting. Four Geometry classes were given weekly formative assessments using DeltaMath, Classkick, and Desmos. The students’ scores from these assessments and opinions were collected and analyzed to find which program would be most beneficial for the classroom. The literature review covers a variety of resources that determine effective classroom teaching in which technology is used within the classroom. The articles vary in what practices most benefit the students when utilizing online assessments, and allows a better view into what processes should be considered before implementing online assessments into a classroom. This research was done in a specific classroom, and the results may not be the same if utilized in any other classroom, but the data gives some valuable insight to allow others to make a choice in what program may be most effective for their classroom as well

An Open Context for Near Eastern Archaeology

The common use by archaeologists of ubiquitous technologies such as computers and digital cameras means that archaeological research projects now produce huge amounts of diverse, digital documentation. However, while the technology is available to collect this documentation, we still largely lack community-accepted dissemination channels appropriate for such torrents of data. Open Context aims to help fill this gap by providing open access data publication services for archaeology. Open Context has a flexible and generalized technical architecture that can accommodate most archaeological datasets, despite the lack of common recording systems or other documentation standards. It includes a variety of tools to make data dissemination easier and more worthwhile. Authorship is clearly identified through citation tools, including web-based publication systems that enable individuals to upload their own data for review, and collaboration is facilitated through easy download and "tagging" features. Near Eastern archaeologists will benefit from Open Context's flexibility to share a variety of content from diverse projects, no matter how large or small.

Nitrogen and Phosphorus Recalibration for Sunflower in North Dakota

Sunflower is one of the most important annual crops grown for edible oil in the world and is grown in North Dakota and the northern Great Plains more than any other region in the United States. Sunflower production and sunflower itself has evolved significantly since commercial cultivation began in the 1970s. In order to properly update fertility requirements of nitrogen and phosphorus in the northern Great Plains to correspond to this evolution, sunflower yield and oil concentration response to nitrogen and phosphorus fertilizer was investigated based on a twoyear (2014-2015) study. Highly significant statistical relationships between sunflower yield and oil concentration were found with nitrogen fertilizer rate but were not found with phosphorus fertilizer rate. This indicates that nitrogen fertilizer application rates used for sunflower need to be determined by current documented responses and that phosphorus fertilizer may not be needed to produce optimal yield and oil concentration of sunflower.National Sunflower Associatio

Presence-at-hand

Abstract The writing that follows is intended to provide a theoretical framework for the motives behind my practice. The primary concerns addressed are the reception, transmission, and physical shape of knowledge. I will discuss a human condition that exists as a byproduct of both the legacy of representation as well as the innate biology of the brain. I will argue that as a society we are governed by the residue of an extreme logic, and that this condition places severe margins on our potential for creative solutions. I will propose that our ability to create meaning is stifled by the nature of representation itself—and that the overwhelming presence of logic in the mind fosters an unfavorable environment for radical ideas to occur. Through focusing on the limitations of language and habits of the mind topics will explore my work, and the role of art, as a site for the emergence of an unconventional kind of relearning

HaloDaSH: The Deep and Shallow History of Aquatic Life\u27s Passages between Marine and Freshwater Habitats

This series of papers highlights research into how biological exchanges between salty and freshwater habitats have transformed the biosphere. Life in the ocean and in freshwaters have long been intertwined; multiple major branches of the tree of life originated in the oceans and then adapted to and diversified in freshwaters. Similar exchanges continue to this day, including some species that continually migrate between marine and fresh waters. The series addresses key themes of transitions, transformations, and current threats with a series of questions: When did major colonizations of fresh waters happen? What physiographic changes facilitated transitions? What organismal characteristics facilitate colonization? Once a lineage has colonized freshwater, how frequently is there a return to the sea? Have transitions impelled diversification? How do organisms adapt physiologically to changes in halohabitat, and are such adaptive changes predictable? How do marine and freshwater taxa differ in morphology? How are present-day global changes in the environment influencing halohabitat and how are organisms contending with them? The purpose of the symposium and the papers in this volume is to integrate findings at multiple levels of biological organization and from disparate fields, across biological and geoscience disciplines
