Dna: Modeling Structure And Function, Jennifer A. R. Smith, Cynthia J. Martin
Iowa Science Teachers Journal
This article presents a developmentally appropriate approach to introduce high school biology students to the structure of DNA and illustrate how its structure and function are related. We address the importance of beginning instruction with a concrete representation of DNA, and using it to scaffold to several important biological concepts. We also make clear the teacher's crucial role in this scaffolding process. This article promotes National Science Education Content Standards C and G, and Iowa Teaching Standards 1, 2, 3, 4, and 7.

Synergistic Relationships: Why Effective Teaching Is Complex, Michael P. Clough
Iowa Science Teachers Journal
The crucial role of teachers in creating powerful learning environments has been a consistent feature of editorials and articles appearing in ISTJ under my editorship. Research makes clear that what teachers do significantly impacts their students' achievement, interest in a field of study, and attitude toward schooling in general. The cognitive and affective climate of classrooms is influenced by the learning and behavioral expectations set by teachers, the activities and instructional strategies they choose, the behaviors they exhibit when interacting with students, and many other important teacher decisions.

On Cloud 9: Helping Students Relate The Concept Of Differential Heating To Changes In Weather, Elizabeth White, Morgan Pett
Iowa Science Teachers Journal
Understanding the basic features that drive the weather is important for understanding weather forecasting. In this activity students investigate differential heating and then connect that understanding to weather. Students are required to design a procedure, collect data, and make sense of that data. These investigative skills require students to be mentally engaged, and better model what scientists do while highlighting the inquisitive nature of science. This activity promotes National Science Education Standards A, B, D, and G and Iowa Teaching Standards 1, 2, 3, and 6.

How Are We Stacking Up?: Current Reforms In Science Education Twelve Years After Publication Of The National Science Education Standards, Robert E. Yager
Iowa Science Teachers Journal
In education Science-Technology-Society (STS) is commonly viewed as another add-on to a course or the curriculum. This view portrays STS as being plagued with the same problems as traditional teaching of science and technology; information is transmitted to students by lecture, verification laboratories, or textbooks and other written materials. This article presents the case that STS instruction, when effectively implemented, captures more broadly key aspects of both science and technology, and does not succumb to the common problems of traditional instruction. Essential characteristics of effective science teaching are presented.

What Is So Important About Asking Questions?, Michael P. Clough
Iowa Science Teachers Journal
Effective teaching promotes a highly interactive environment. Creating and maintaining that kind of atmosphere is very complex. While interesting and developmentally appropriate content, tasks, activities and materials spark students' curiosity and set a stage for learning, the actions of teachers orchestrate the necessary interaction that results in desired conceptual understanding. My editorial in the last issue of ISTJ stressed the teacher's crucial role in helping students learn through inquiry. Here I will focus on one aspect of that role – questioning.

What I Believe About Leadership And Education : A Reflective Essay, Angela C. Fogle
Graduate Research Papers
Leadership in 21st century education will become one of the most important cultural necessities, if education is to serve our society appropriately and move it forward to adjust to the challenges of the future. Leaders in education must be prepared to embrace new and challenging roles that will guide educational leadership into the future. Those roles will include: instructional leadership, organizational leadership, ethical leadership, visionary leadership, and collaborative leadership. As the educational leaders of the future move to incorporate these leadership styles into practice, education will be able to move forward in a positive and successful direction.
Sandplay With Children In The School Setting, Sophie I. Banwarth
Sandplay With Children In The School Setting, Sophie I. Banwarth
Graduate Research Papers
Sandplay therapy, developed by Margaret Lowenfeld, is a technique where children choose miniature objects to place in a sand tray to create a concrete representation of their internal struggles. The counselor's role is to create a safe and protected environment and does not impose personal suggestions or ideas. The counselor can choose to facilitate different types of sandplay with a child: directed, nondirected, static, moving, or interactive. Sandplay therapy offers techniques such as hide and seek, family sand trays, mazes, and self-figures. Sandplay therapy is effective with children in the school setting. Teachers report that students return to class more …

Weather Factors Influencing Winter Roosts Of American Crows In Central Iowa, Joshua D. Obrecht, Stephen J. Dinsmore
Weather Factors Influencing Winter Roosts Of American Crows In Central Iowa, Joshua D. Obrecht, Stephen J. Dinsmore
Journal of the Iowa Academy of Science: JIAS
We investigated the effects of season and weather on the winter roosting behavior of American Crows (Corvus brachyrhynchos) in central Iowa from January through March 2006. The peak number of birds recorded at a roost in Ames, Story County was 9,000+ in early February, and the number of individuals entering the roost decreased through February and March. Crows tended to enter the roost later in the day as winter neared completion. High wind speed and low light intensity caused individual to enter the roost earlier in the day. Temperature did not affect arrival time of crows. Wind speed, light intensity, …

Free Clinics Of Iowa: An Inside Look At An Alternate Route To Healthcare, Laura Deboer
Honors Program Theses
Forty-seven million uninsured Americans: an all too familiar statistic, peppering television advertisements, newspaper headlines, and most recently - a hot agenda item of political candidates is a sad truth of American health care. Unfortunately, for sixteen percent of Americans and approximately thirteen percent of adult Iowans, this is not just a passing television ad - but the facts of life that are faced every day. These individuals make up families who evaluate that, although it is taking a risk to be without health insurance, the security of insurance is not as important as providing meals on the dinner table. The …

Sarbanes-Oxley - From Idea To Implementation: A Look At The Impact On Public Companies, Stephanie Lynn Johnson
Honors Program Theses
While the new requirements of the Sarbanes-Oxley Act might seem like an excellent step towards improving the honesty, integrity, and reputation of the corporate accounting world, the actual implementation of these regulations is proving to be quite a headache for public companies and their auditors. Congress developed new rules for publicly held companies, but they failed to provide any guidelines or best practices for companies to follow in the compliance process. In addition, the costs of implementing the various provisions of SOX are adding up to be much higher than originally anticipated, creating a burden for smaller public companies. This …
The Private Rates Of Return To Undergraduate Education By Major, Nick Johnson
The Private Rates Of Return To Undergraduate Education By Major, Nick Johnson
Honors Program Theses
The private returns to undergraduate education are important to understand for high school graduates trying to decide between the work force and college. The IRR method is the best measure of the private returns to education because it allows for important variables to be accounted for and includes the time value of money. Using data from the National Longitudinal Study of 1972, there are large differences in the returns to college by major. This model allows the returns to college to vary by college selectivity and, through ability, within an individual major.
