What’S My Motivation? Ideas For Rethinking Student Assessment, Jerrid Kruse Jan 2011

What’S My Motivation? Ideas For Rethinking Student Assessment, Jerrid Kruse

Iowa Science Teachers Journal

Three of the articles in this issue of the Iowa Science Teachers Journal address assessment in the science classroom. Jesse Wilcox and Frank Noschese each discuss standards-based grading (SBG). Frank provides examples of his approach to SBG in his physics classes and makes a strong case for SBG while Jesse adds detail by sharing the frameworks he uses to inform and implement his SBG practices. Joe Bower goes a bit further by encouraging readers to consider why we assign grades at all. Each of the articles raises important, and related, points about the connection between assessment and motivation.

Wiggling Worms: Using The Learning Cycle In An Elementary Classroom To Study Variation, Lori Marie Ihrig, Jennifer Nicole Prindle

Iowa Science Teachers Journal

In grades K-2, students are at an age when they start to look closely at living things around them. They can comprehend that while individuals may be of the same kind (i.e., kittens from the same litter), they possess differences. This article uses the learning cycle to engage students in making observations and measurements about plants and animals in order to help them understand “there is variation among individuals of one kind in a population” (AAAS, 1993, p. 107). This article promotes National Science Education Standards A and C, and Iowa Teaching Standards 1, 2, 3, 4, 5, and 6.


Hot Conceptual Change - You’Ve Got To Have Faith, Jerrid Kruse, Michael P. Clough Jan 2011

Hot Conceptual Change - You’Ve Got To Have Faith, Jerrid Kruse, Michael P. Clough

Iowa Science Teachers Journal

In the last editorial (Kruse and Clough, 2010), we addressed some common concerns educators raise when considering inquiry-based instruction. Addressing such concerns is of utmost importance to address the plausibility, intelligibility and fruitfulness of inquiry-based teaching. Unfortunately, such issues are not all that affect willingness to enact inquiry-based teaching. More personal and contextual factors also play a part in all learning, including learning how to teach more effectively.

Learning Under Pressure: Teaching Boyle’S Law Through Inquiry, Meagan Woestman, Adam Kent Jan 2011

Learning Under Pressure: Teaching Boyle’S Law Through Inquiry, Meagan Woestman, Adam Kent

Iowa Science Teachers Journal

Boyle’s law is commonly addressed in chemistry and physical science textbooks, but rarely in a manner consistent with what we know best promotes learning (Bransford, Brown & Cocking, 2000). We present the standard syringe activity as an exploratory inquiry experience followed by a more formal development of the relationship. The activity starts and concludes by having students examine how the volume of a crushed pop bottle changes in a vacuum. Through iterative concrete experiences and guided discussions, students construct Boyle’s law to account for the class data. This article address National Science Education Standards A, B, E, G, and Iowa …

The Buds And The Bees: Inquiry Into The Sexual Reproduction Of Plants, Timothy D. Goodman, Laurence H. Woodruff

Iowa Science Teachers Journal

Many students have few significant experiences investigating flower structure and function, yet are expected to understand sexual reproduction in angiosperms. We present here an inquiry-based hands-on activity where middle school students compare plant reproduction to more commonly understood animal reproduction. This provides a foundation to more deeply understand topics related to plant reproduction. This activity also provides many opportunities to explicitly address the nature of science and how science works. This article addresses National Science Education Content Standards A, C, and G, and Iowa Teaching Standards 1, 2, 3, 4, and 5.


Flood Frequency Estimation By Neyman-Scott Rectangular Pulse Rainfall Model And Topmodel, Richard Bernatz Jan 2011

Flood Frequency Estimation By Neyman-Scott Rectangular Pulse Rainfall Model And Topmodel, Richard Bernatz

Journal of the Iowa Academy of Science: JIAS

A spatial-temporal Neyman-Scott Rectangular Pulse (NSRP) stochastic rainfall model is developed for seasonal-continuous simulation to project annual discharge probabilities from a relatively small watershed, the 1395 km2 Upper Iowa River watershed upstream from Decorah, Iowa. NSRP rainfall data is used as rainfall input to TOPMODEL, a conceptual, semidistributed rainfall runoff model, to calculate river discharge at a site common to the United States Geological Survey (USGS) gauging station in Decorah, Iowa. Annual peak flows based on simulated rainfall are used to fit a log-Pearson type III distribution to project 1 %-, 0.2%-, and 0.1 %-annual discharges. These results are compared …

The Birds Of Chichaqua Bottoms Greenbelt (Polk County, Iowa): Patterns Of Habitat Use And Implications For Management, Keith Summerville, Joel Boyles, Loren Lown Jan 2011

The Birds Of Chichaqua Bottoms Greenbelt (Polk County, Iowa): Patterns Of Habitat Use And Implications For Management, Keith Summerville, Joel Boyles, Loren Lown

Journal of the Iowa Academy of Science: JIAS

Despite the fact that many birds are believed to be declining as a result of habitat loss and elimination of historic disturbance regimes, few studies have explored how restoration and management of mixed grassland and woodland systems influence bird communities. In this study, we tested whether habitat size, habitat type, and use of prescribed fire as a management tool affected the species richness and composition of bird communities sampled from 22 restored grassland and woodland sites within Chichaqua Bottoms Greenbelt (Polk County, Iowa). In 2004-5 bird communities were sampled by walking transects within each site and recording the presence and …
