An Examination Of Pre-Service Secondary Mathematics Teachers’ Conceptions Of Angles, Melike Yigit

The Mathematics Enthusiast

The concept of angles is one of the foundational concepts to develop of geometric knowledge, but it remains a difficult concept for students and teachers to grasp. Exiting studies claimed that students’ difficulties in learning of the concept of angles are based on learning of the multiple definitions of an angle, describing angles measuring the size of angles, and conceiving different types of angles such as 0-line angles, 1- line angles, and 2-line angles. This study was designed to gain better insight into pre-service secondary mathematics teachers’ (PSMTs) mental constructions of the concept of angles from the perspective of Action-Process-Object-Schema …

Common Sense About The Common Core, Alan H. Schoenfeld

The Mathematics Enthusiast

Is the Common Core the best thing since sliced bread, or the work of the devil? Is it brand new, or a rehash of old ideas? Is it anything more than a brand name, or is there substance? Can it work, given the implementation challenges in our political and school systems? Opinions about the Common Core are everywhere, but the op-eds I’ve seen are often short on facts, and equally short on common sense. A mathematician by training, I’ve worked for nearly 40 years as an education researcher, curriculum materials developer, test developer, standards writer, and teacher. What follows is …

Proper Handling And Transportation Of Eggs For Sale At Kentucky Farmers’ Markets, Anthony J. Pescatore, Jacquie Jacob

Agriculture and Natural Resources Publications

Regardless of the number of eggs produced, and whether the eggs are for home use or sale, careful egg handling is very important. The United States Food and Drug Administration (FDA) lists eggs as a potentially hazardous food, therefore careful handling is important. In Kentucky, if you sell more than 60 dozen eggs a week you need to purchase a retail license. The same holds true if you want to sell your eggs to a retail store to be re-sold or to a distributor that will sell them for you. If you produce fewer than 60 dozen eggs a week …

Sheep Breeding: Heritability, Ebvs, Epds And The Nsip, Debra K. Aaron

Agriculture and Natural Resources Publications

Genetic improvement in a flock depends on the producer’s ability to select breeding sheep that are genetically superior for traits of economic importance. This is complicated by the fact that an animal’s own performance is not always a true indicator of its genetic potential as a parent.

Modeling Colony Collapse Disorder In Honeybees As A Contagion, Christopher Kribs, Christopher Mitchell

Mathematics Faculty Publications - Archive

Honeybee pollination accounts annually for over $14 billion in United States agriculture alone. Within the past decade there has been a mysterious mass die-off of honeybees, an estimated 10 million beehives and sometimes as much as 90% of an apiary. There is still no consensus on what causes this phenomenon, called Colony Collapse Disorder, or CCD. Several mathematical models have studied CCD by only focusing on infection dynamics. We created a model to account for both healthy hive dynamics and hive extinction due to CCD, modeling CCD via a transmissible infection brought to the hive by foragers. The system of …

Inbreeding In Sheep, Debra K. Aaron

Agriculture and Natural Resources Publications

Inbreeding is broadly defined as the mating of individuals that are related. Strictly speaking, however, all animals within a breed are related. So, in a sense, every purebred sheep producer practices some degree of inbreeding. In most cases this relationship is very slight. Therefore, inbreeding is more practically defined as the mating of individuals more closely related than the average of the breed. This practice includes mating brother to sister, sire to daughter and son to dam.

From Limp Lettuce To Kaleidoscope Salad: Making Your Instruction Sessions Pop For All Patrons With Universal Design For Learning Principles, Christina C. Wray

LOEX Conference Proceedings 2012

Universal Design for learning is an instructional design framework that promotes inclusive classrooms and environments where multiple learners at multiple levels are learning together in a general education setting. The fundamental idea of universal design is that you can teach material in a way that is accessible to ALL learners instead of being designed for a specific ability level. The Universal Design for Learning framework takes it a step further and introduces three key concept. When designing instruction we should:

• Provide multiple means of representation

• Provide multiple means of expression

• Provide multiple means of engagement

This can …

Association Of G-Quadruplex Forming Sequences With Human Mtdna Deletion Breakpoints, D. W. Dong, F. Pereira, Steven Paul Barrett , '13, J. E. Kolesar, K. Cao, J. Damas, Liliya A. Yatsunyk, F. B. Johnson, B. A. Kaufman

Chemistry & Biochemistry Faculty Works

Background: Mitochondrial DNA (mtDNA) deletions cause disease and accumulate during aging, yet our understanding of the molecular mechanisms underlying their formation remains rudimentary. Guanine-quadruplex (GQ) DNA structures are associated with nuclear DNA instability in cancer; recent evidence indicates they can also form in mitochondrial nucleic acids, suggesting that these non-B DNA structures could be associated with mtDNA deletions. Currently, the multiple types of GQ sequences and their association with human mtDNA stability are unknown. Results: Here, we show an association between human mtDNA deletion breakpoint locations (sites where DNA ends rejoin after deletion of a section) and sequences with G-quadruplex …

First Proof Of Concept Of Sustainable Metabolite Production From High Solids Fermentation Of Lignocellulosic Biomass Using A Bacterial Co-Culture And Cycling Flush System, Wanying Yao, Sue E. Nokes

Biosystems and Agricultural Engineering Faculty Publications

To improve the lignocellulose conversion for ABE in high solids fermentation, this study explored the feasibility of cycling the process through the cellulolytic or/and solventogenic phases via intermittent flushing of the fermentation media. Five different flushing strategies (varying medium ingredients, inoculum supplement and cycling through phases) were investigated. Flushing regularly throughout the cellulolytic phase is necessary because re-incubation at 65 °C significantly improved glucose availability by at least 6-fold. The solvents accumulation was increased by 4-fold using corn stover (3-fold using miscanthus) over that produced by flushing only through the solventogenic phase. In addition, cycling process was simplified by re-incubating …

Why Evidence Matters: Examining The Knowledge And Perception Of Pre-Service Teachers, Stefanie Campbell

HIM 1990-2015

Evidence-based educational policymaking has become a global phenomenon (Wiseman, 2010). According to the Institute of Education Sciences, evidence-based education is "an integration of the professional wisdom and the best available empirical evidence on making decision about how to deliver instructions" (IES, US Department of Education, 2012). This suggests that best practice requires teachers to ensure that instructional strategies and programs implemented in their classroom have been studied in scientific experiments to determine their effectiveness. The general public, as well as practicing teachers, holds an assumption that educators have knowledge as to what is evidence-based education. However, this is not always …

Role Of Sesemat Led Continuous Professional Development On Mathematics Teachers’ Practice, Wamala Francis

Master of Education

The study aimed at exploring and understanding the role of the CPD provided the SESEMAT (on teachers’ practice). SESEMAT is the Secondary Science and Mathematics Teachers’ Program in Uganda. The results were arrived at using a questionnaire and oral interviews with four mathematics teachers, two deputy head teachers, one head teacher and one SESEMAT national trainer. Also lesson observations and document analysis were employed as data generation tools. The study is important because SESEMAT has been offering CPD over a period of time. However there is little understanding about the role of SESEMAT on teaching practice. Second I had a …

Head Teacher’S Uptake Of Continuous Professional Development Activities In School Leadership: A Case Of School Health And Reading Program In Uganda, Bariyo Nelson

Master of Education

School improvement largely depends on the quality of school leadership which is also determined by the quality of and sustained professional development of the teaching cadres. School improvement can be possible if teacher participation in leadership is empowered by the leadership skills from the head teacher. In order to ensure school improvement, head teachers need to integrate continuing professional development activities in their school leadership. This study on the head teacher’s uptake of School Health and Reading Program (SHRP) in school leadership was conducted in a public primary school in south-western Uganda to explore how the head teacher integrated SHRP …

How Can Inquiry-Based Teaching Approach Be Used By Physics Teachers In A Rural Secondary School To Improve Students’ Participation In Learning Physics? A Case Study Of A Rural Public Secondary School In Kanungu District In Uganda., Mugimba Kenneth Oryateisa

Master of Education

Several researchers have published that there is a decline in the number of students interested in studying science today. They attribute this to the poor methods of teaching used by science teachers in schools today. They assert that there is no correlation between what is taught in science lessons and its relevance in real world. For that reason students fail to know the implications of studying science and its use in everyday life. One prospective way of improving students’ interest and motivation to learn science will be the teaching of science lessons using inquiry activities that will improve students’ participation …

Mathematics Teaching Efficacy, Mwakulia Emily Sau

Master of Education

The affective domain has lately drawn the attention of mathematics research community. A key finding from the research literature is that an individual’s efficacy, that is, the belief in their ability to overcome challenges and bring about the desired results can influence one’s motivation to embark on the task and invest time and resources. This study examines teachers’ beliefs about their mathematics teaching efficacy which is rarely studied in Africa including Kenya. The field work was based on a sample of primary school teachers in Voi Sub-County. The study employed a sequential mixed method approach in which a survey was …

An Exploration Of The Role Of School Leadership In Implementation Of Learner-Centered Pedagogy In Teaching Mathematics: A Case Of A Secondary School In Tanzania., Rehema Mdoe

Master of Education

School leadership is an entity that has potential to bring changes for the improvement of schools, as a contextual factor it can affect teachers’ practices and improve students’ performance. With the continued failure in mathematics among secondary school students, school leadership can be explored to see how can influence mathematics teachers to use learner-centered pedagogy in teaching mathematics as the new curriculum of 2005 advocate. This dissertation report is therefore about the exploration of the role of school leadership (SL) in implementation of learner-centered pedagogy (LCP) in teaching of mathematics: a case of secondary school in Tanzania. Using qualitative case …

Integration Of Multimedia In The Teaching And Learning Of Physics: How Can It Influence Student Classroom Engagement?, Cockgen Omondi Limonya

Master of Education

Considered as a multidimensional construct, student engagement has been the focus of educational research for over a decade. Educational researchers have been interested in student classroom engagement because it is opined as one of the ways through which student academic achievement, which has been cited as poor in physics, can be improved. Unfortunately, physics teachers in Kenya have not been able to engage their learners leading to the poor performance in physics. Studies have shown that multimedia integration in teaching and learning enhances student classroom engagement. The current study therefore aimed to examine the relationship between multimedia integration in the …

The Head Teacher’S Experience In Dealing With Noncompliant Teachers In A Secondary School: A Case Of A School In Arua District, Uganda., Okecha Patrick

Master of Education

Effective school leadership is linked to proper management of discipline of teachers that improves teaching and learning of students. Management of teachers’ misconduct is believed to be possible with the head teacher applying the teachers’ discipline management procedures established by MoES. Commitment and discipline of teachers are the key factors to effective curriculum delivery to the students. The issue of noncompliant teachers does not only affect teaching and learning in schools, but also give head teacher hard time to deal with it.This study on head teacher’s experience in dealing with noncompliant teachers was conducted in one secondary school in Uganda …

Exploring The Impact Of Maths Anxiety On Students’ Cognitive Engagement, Timothy Mugendi Njagi

Master of Education

Mathematics is internationally accepted as a core subject of great importance, with pressure on students and teachers to achieve as highly as possible. Against a concern in Kenya about low mathematics attainment, this study examines the phenomenon of ‘maths anxiety’, i.e. anxiety experienced when attempting to do, or thinking about mathematics, whether in the classroom or elsewhere. Key themes from the background literature include connections with physical, emotional and psychological disorientation, impairing the logical reasoning skills required for the high order thinking necessary for learning mathematics. A mixed methods case study design was used, set in one mixed secondary school, …

The Fluid Dynamics Of Mercury Target Delivery And Exhaust For A Muon Collider Particle Production System, Yan Zhan

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

Liquid mercury has been investigated as a potential high-Z target for the production of Muon particles for the Muon Collider project. This thesis investigates the dynamics of mercury flow in a design of the target delivery system, with the objective of determining pipe configurations that yield weak turbulence intensity at the exit of the pipe. Curved circular pipes with various half-bend angles, with/without nozzles in the exit region, and with/without welds on the pipe inner surface are studied. Theoretical analysis is carried out for steady laminar incompressible flow, whereby the terms representing curvature effects are examined. Subsequent simulations of the …

Quantifying The Basal Conditions Of A Mountain Glacier Using A Targeted Full-Waveform Inversion: Bench Glacier, Alaska, Usa, E. Babcock, J. Bradford

Geosciences Faculty Publications and Presentations

Glacier dynamics are inextricably linked to the basal conditions of glaciers. Seismic reflection methods can image the glacier bed under certain conditions. However, where a seismically thin layer of material is present at the bed, traditional analyses may fail to fully characterize bed properties. We use a targeted full-waveform inversion algorithm to quantify the basal-layer parameters of a mountain glacier: thickness (d), P-wave velocity (α) and density (ρ). We simultaneously invert for the seismic quality factor (Q) of the bulk glacier ice. The inversion seeks to minimize the difference between the data …
