Smaf: A Soil Health Assessment Tool, D. L. Karlen, C. D. Nance, D. L. Dinnes, D. W. Meek

Journal of the Iowa Academy of Science: JIAS

The Soil Management Assessment Framework (SMAF) was developed to help quantify soil quality/health effects of tillage, crop rotation, and other soil management practices. Our objective was to determine if the SMAF could detect soil health differences after growing a single winter triticale (X Triticosecale Wittmack) crop. Soil samples were collected from 0 to 7.5- and 7.5 to 15- cm depth increments during the 2003 – 2004 and 2004 – 2005 growing seasons near Ames and Lewis, IA, and analyzed for several potential soil quality indicators. The SMAF analysis showed higher soil quality ratings for surface than subsurface samples. It also …

Connected Mathematics Learning And Gender Equity In Predominantly Latino/A High Schools: Case Of Spatial Reasoning, Raymond Falcon

Open Access Theses & Dissertations

This study analyzed interventions used in improving the mathematics achievement in spatial reasoning tasks for females called connectedness. Gender achievement in mathematics has been a controversial topic because of the wide variance in research. Some research has found a difference between the genders in mathematics while others argue there is no difference in mathematical achievement. The Seven Clever Piece Tangrams were used in the mixed method study as the instrument of spatial reasoning tasks. Freshmen participants (N=719) from southwest high schools in a border town participated in one of two groups: control (n=247) and treatment (n=472). Of the participants, 379 …

Investigating The Validity Of A Survey Intended To Gauge Mathematics Problem-Solving Disposition Along The Impulsive-Analytic Dimension, Miguel Mendoza

Open Access Theses & Dissertations

This study investigates the validity of the Likelihood-to-Act (LtA) survey developed to assess respondents' problem-solving disposition along the impulsive-analytic dimension. Sixteen pre-service teachers were strategically selected from a pool of 495 LtA survey respondents to participate in a semi-structured task-based interview approximately one hour in length. The interview consisted of three main parts: a problem solving section, a consistency section, and a classification section.

* Part 1 of the interview was developed to get interviewees to solve five open-response problems meant to elicit an impulsive response. Interviewees were also asked to verbalize their thought process in order for the researchers …

Increasing Automaticity, Sara Burns

Online Theses and Dissertations

Automaticity is defined as the process of developing fluency in mathematics and the ability to answer a basic math problem routinely. Automaticity is one of the most important skills that a student can possess in mathematics. While there are many ways that an educator can implement strategies to increase automaticity in the classroom, the purpose of this study was to determine which of these methods of implementation is more effective: requiring students to practice automaticity three times per week or requiring students to practice automaticity five times per week.

Student Attitude Toward Mathematics At The Middle And High School Level, Anna Berglund

WWU Honors College Senior Projects

The question of attitude toward mathematics is one of great importance and one that is associated with large implications for students. Studies on student attitude focus on determining the relationship of attitude to the perceived relevance of mathematics to future academic and career choices. Student attitude toward math in middle and high school can affect student enthusiasm for taking advanced math courses in high school and college and can largely determine future career choices. For these reasons generating positive attitudes toward mathematics among middle and high school students is an important goal of mathematics education.

York River Water Quality Curriculum: Using Real Water Quality Data To Investigate Water Quality Cycles And Answer Applied Marine Science Questions, Bob Carroll, Sarah Mcguire

Reports

Considering that Virginia has approximately 50,000 miles of rivers and streams, 2,500 square miles of estuarine water and 100 lakes greater than 100 acres, water quality monitoring with your students is a great hands-on activity that gets students thinking about the properties and processes occurring in classroom aquaria, lake, stream, river, estuarine and marine environments. It can be difficult to elucidate water quality patterns or trends with student generated data due to the low number of samples taken, the possibility of inaccurate results due to user error or expired test kit reagents as well as the innate lack of accuracy …

Developing And Assessing Curriculum On The Physics Of Medical Instruments, Warren Christensen, James K. Johnson, Grace R. Van Ness, Elliot E. Mylott, Justin C. Dunlap, Elizabeth A. Anderson, Ralf Widenhorn

Physics Faculty Publications and Presentations

Undergraduate educational settings often struggle to provide students with authentic biologically or medically relevant situations and problems that simultaneously improve their understanding of physics. Through exercises and laboratory activities developed in an elective Physics in Biomedicine course for upper-level biology or pre–health majors at Portland State University, we aim to teach fundamental physical concepts, such as light absorption and emission and atomic energy levels, through analysis of biological systems and medical devices. The activities address the properties of electromagnetic waves as they relate to the interaction with biological tissue and make links between physics and biomedical applications such as microscopy …

Math Education At Its Prime?, Natalie Benet

Senior Honors Theses

Three main problems with current math education are negative mindsets toward math, the lagging comparison with advanced education in other countries, and ill-equipped teachers and school systems. The consequences of these problems have impacted math education by convincing students that they do not need to try at math, filling countless classrooms with ill-qualified teachers, and overall lowering the quality of U.S. math education compared to the education of rest of the world. In order to correct these problems and reverse the present and future consequences, the quality of math education must be increased. This can be done by changing the …

A Comparative Analysis Of Point-Of-View Modeling For Industrial And Technology Education Courses, Petros J. Katsioloudis, Todd D. Fantz, Millie Jones

STEMPS Faculty Publications

(First paragraph): Enrollment in technology education at the college level has been declining (Isbell & Lovedahl, 1989; Volk, 1997; Daugherty, 1998; Hill, 1999; Ndahi & Ritz, 2003; Moye, 2009). It is essential for technology teacher educators to investigate ways to increase the enrollment in their programs, or the profession may fail to provide technology teachers in the future (Ndahi & Ritz, 2003). A solution that several institutions with technology education programs have adopted is the offering of the program via distance learning. Distance learning “allows participants to collapse time and space” (Cole, 2000, p. ix). According to Flowers (2003) technology …

Product Lifecycle Management: Measuring What Is Important - Product Lifecycle Implementation Maturity Model, Abram Walton, Cynthia Tomovic, Michael Grieves

STEMPS Faculty Publications

Industry reports that benefits of PLM are difficult to assess because the same benefit can be expressed as a function of time, cost, quality, or any combination. Based on a review of the PLM literature in an earlier study, a PLM Process Model and an initial list of PLM related metrics was generated and later confirmed through interviews with experienced PLM users. In the current study, the original PLM Process Model was refined and the list of metrics was subjected to an exploratory factor analysis in which specific metrics were found to be related to one of four factors: Inputs, …

The Impact Of Teachers' Characteristics And Self-Reported Practices On Students' Algebra Achievement, Liza Cope

Legacy Theses & Dissertations (2009 - 2024)

This study examined the impact of teachers' characteristics and self-reported practices on students' Algebra achievement while controlling for students' characteristics. This study is based on the secondary analysis of data collected from a nationally representative sample of 9th grade students and their mathematics teachers during the base year of the High School Longitudinal Study of 2009 (HSLS). Student and teacher data were obtained through questionnaires and students' Algebra achievement was measured by an ability-adaptive assessment designed to measure a cross-section of understandings representative of the six major Algebraic content domains (The language of algebra; Proportional relationships and change; Linear equations, …

Dismantling The Birdcage : Adolescent Girls' Attitudes Towards Learning Mathematics With A Relational Pedagogy In A Problem-Based Environment, Carmel Schettino

Legacy Theses & Dissertations (2009 - 2024)

Although the Gender Achievement Gap is closing in mathematics, the "interest gap" in pursuing STEM fields is not. Mathematics education research has discussed constructivist, student-centered and inclusive methods of teaching that have been found to encourage students that have underachieved and been underrepresented in STEM fields. One recommendation for encouraging young women to continue in their mathematical studies is to find instructional methods that allow them to feel included in the learning process and "unfix" the dichotomous, gendered socio-cultural view of mathematics and the mathematics classroom fostering positive attitudes such as self-confidence, empowerment and agency.
