Providing Preservice Teachers With Worthwhile Field-Based Experiences In Mathematics, Glenn Nelson Jan 2011

Providing Preservice Teachers With Worthwhile Field-Based Experiences In Mathematics, Glenn Nelson

Faculty Work

Providing preservice teachers with worthwhile field-based experiences is recognized as an important component in their development as good teachers. Because mathematics instruction in general has moved from a teacher-directed, procedurally-focused process to a more student-centered, conceptually-oriented approach, preservice mathematics education classes – especially methods courses - should reflect this shift as well. Field-based opportunities can be instances for preservice teachers to personally experience such a shift to real-world relevance.


Exploring Literacy Across The Curriculum: Writing In The Mathematics Classroom, Sarah E. Heddinger Jan 2011

Exploring Literacy Across The Curriculum: Writing In The Mathematics Classroom, Sarah E. Heddinger

Honors Program Theses

The purpose of my Honors thesis is to find evidence that writing in mathematics benefits both students and teachers. To research this claim, I viewed how writing takes place in mathematics within a specific elementary classroom. I hoped to view mathematics lessons in which literacy, specifically writing, was involved as an integral part of every lesson.


Maggie And Her Students: Talking And Reasoning In A Reform-Based Mathematics Classroom, Debra Louise Semm Rich Jan 2011

Maggie And Her Students: Talking And Reasoning In A Reform-Based Mathematics Classroom, Debra Louise Semm Rich

Dissertations and Theses @ UNI

In this qualitative case study, I explored how Maggie, the teacher, and her students used language to advance students' conceptual understanding of mathematics in a reform-based mathematics classroom. Specifically I sought to describe how Maggie's reform-based mathematics classroom environment impacted the quantity and quality of mathematical language spoken by her students. Maggie's eighth-grade mathematics classroom was observed during a course of study on data and statistics. Three semi-structured interviews with Maggie, artifacts provided by her, and fourteen 52-minute classroom lessons, supported with field notes, were analyzed.

Environmental themes were revealed as they related to Maggie, her beliefs, goals, knowledge, and …


Determining Students' Working Conceptions Of Evolution Through Formative Assessment Probes, Danielle J. Burras Jan 2011

Determining Students' Working Conceptions Of Evolution Through Formative Assessment Probes, Danielle J. Burras

Dissertations and Theses @ UNI

Students entering a science classroom bring with them many ideas about science content and the nature of science. Some of those ideas are not congruent with current scientific explanations and can be called working conceptions. Working conceptions have the ability to impact how students respond to new information and whether or not they integrate it into their lives outside of the classroom. Identifying what working conceptions students have prior to instruction allows educators to determine how instruction should be formatted and what concepts may need extra focus. The purpose of this investigation was to determine the effectiveness of formative assessment …


Using Novels In The Science Classroom, Hannah Llewellyn Haarhues Jan 2011

Using Novels In The Science Classroom, Hannah Llewellyn Haarhues

Dissertations and Theses @ UNI

Reading is a key factor in the success of students through their school years as well as their lives. With Americans reading less and falling behind in subjects as they progress through the school system, reading is the subject area that benefits all aspects of their schooling. Studies done from the 1990s on have shown successful reading programs improve standardized test scores of school age students. Trade books in place of textbooks had been explored, but only in middle school or younger. This study uses a survey to explore high school biology students' opinions on reading and science before and …


Barriers That Iowa High School Biology Teachers Face When Teaching Evolution In The Classroom, Joshua Michael Hanna Jan 2011

Barriers That Iowa High School Biology Teachers Face When Teaching Evolution In The Classroom, Joshua Michael Hanna

Dissertations and Theses @ UNI

After decades of court cases, decided in favor of evolution being taught, legal decisions where the incorporation of teaching creationist ideas have been found unconstitutional, and recent strategies and attempts that would have teachers give "equal time" to creation-science ideas; there remains a disparity among Iowa's high school biology teachers when teaching evolutionary concepts in the classroom. Taking a look at what is being taught about evolution in Iowa classrooms, this study takes an in-depth look at what Iowa's biology teachers are teaching when educating their students about evolution, where emphasis is being placed and who is putting the most …

A Balancing Act: Helping Students Understand The Mole Relationship For Balancing Equations, Karl Goldsmith, Matt Jaschen Jan 2010

A Balancing Act: Helping Students Understand The Mole Relationship For Balancing Equations, Karl Goldsmith, Matt Jaschen

Iowa Science Teachers Journal

Stoichiometry can be one of the more challenging topics to teach in high school chemistry. Students often struggle until they realize the ratio from the balanced chemical equation represents mole ratios rather than the mass of each component. The activity presented here provides students with an inquiry based experience with a chemical reaction. During the activity, students seek evidence as to what the coefficients in a balanced chemical equation mean. With teacher guidance, these activities help students (1) connect chemical equations to observations, (2) gain evidence that mass ratios are not useful, and (3) understand the relationship between moles and …


Exploring The Depths: Inquiry To Apply And Deepen Students’ Understanding Of Density, James M. Sleep, Lee Johnson Jan 2010

Exploring The Depths: Inquiry To Apply And Deepen Students’ Understanding Of Density, James M. Sleep, Lee Johnson

Iowa Science Teachers Journal

This activity is designed to deepen students' understanding of the concept of density through scientific inquiry. Students devise procedures to determine the relative and absolute (qualitative and quantitative) densities of several solutions of salt water, and establish a class consensus on their results. Students then apply their findings to estimate the density of an unknown solution. The targeted grade-level for this activity is 8 grade physical science. However, because we know students at all grade levels struggle to understand density, this activity could also be useful in high school Earth science and chemistry. This activity promotes National Science Education Content …


Keeping It Green: Using A Compost To Improve Student Learning, Spencer Mesick, Kayla Hendrix Jan 2010

Keeping It Green: Using A Compost To Improve Student Learning, Spencer Mesick, Kayla Hendrix

Iowa Science Teachers Journal

This article discusses ways in which composting might be used to mentally engage students with science content. Incorporating a compost pile in the classroom provides ample connections to future science content (e.g., conditions necessary for the life of organisms in a well running aerobic compost, what decomposition means in a biological sense, aerobic vs. anaerobic decomposition, food webs, respiration, recycling of nutrients, landfill issues, etc.). Also, reflecting the complexities of effective science teaching, the article makes clear the crucial role of the teacher during the activity. The science content and activity addressed in this article are appropriate for 9th - …

Conceptual Change: It’S Not Just For Teaching Science, Michael P. Clough, Jerrid Kruse Jan 2010

Conceptual Change: It’S Not Just For Teaching Science, Michael P. Clough, Jerrid Kruse

Iowa Science Teachers Journal

Mark Twain is often given credit for saying, “It ain't what you don't know that gets you into trouble. It's what you know for sure that just ain't so.” Science teachers likely resonate with this quote because we know our students come to class confidently holding many ideas about the natural world that “just ain't so.”


Impact!: Improving Student Learning Through An Inquiry Crater Investigation, Blake J. Williams, Derek J. Hollingshead Jan 2010

Impact!: Improving Student Learning Through An Inquiry Crater Investigation, Blake J. Williams, Derek J. Hollingshead

Iowa Science Teachers Journal

The fight against student compartmentalization of science concepts is an ongoing battle for all science educators. When an inquiry-based investigation of natural phenomena, like that presented here, is integrated into curricula new links between science concepts are created. These new connections promote a deep and robust understanding of science content. This cratering activity has students applying prior knowledge of gravitational forces, momentum, conservation of energy, and density while exploring the intricate relationships between these fundamental concepts. This activity also provides abundant opportunities for explicit connections to the nature of science. Impact cratering is a phenomena which can be easily modeled …


Thinking On Paper: Using Science Notebooks To Increase Active Engagement In The Elementary Science Classroom, Kimberly R. Gasaway Jan 2010

Thinking On Paper: Using Science Notebooks To Increase Active Engagement In The Elementary Science Classroom, Kimberly R. Gasaway

Iowa Science Teachers Journal

The need for scientific literacy is becoming a new standard to which school districts are being held accountable. Student inquiry and the ability to “think like a scientist” will increase the depth at which students understand the natural world and make connections that are critical in strengthening students' scientific literacy. In addition, research has shown that when students were actively engaged in the learning process, they participated more enthusiastically and retained the concepts being taught. Science notebooks help students learn to record and make sense of data and observations about the natural world and come to deeper understanding of scientific …

The Price Of Inquiry: Managing Open-Inquiry Through Scaffolding And Faux Grant Writing, Shawn Cornally Jan 2010

The Price Of Inquiry: Managing Open-Inquiry Through Scaffolding And Faux Grant Writing, Shawn Cornally

Iowa Science Teachers Journal

Open-inquiry involves students asking their own questions, designing their own investigation, and creating their own explanations in order to learn about the natural world. However, implementing open-inquiry is often daunting for teachers and frustrating for students. This article discusses how I use guided inquiry to help students prepare for open-inquiry and a faux grant process to manage open-inquiry in my class. This activity promotes National Science Education Content Standards A, B, E, G, and Iowa Teaching Standards 1, 2, 3, 4, 5, and 6.


When Dissatisfaction Is A Good Thing, Michael P. Clough, Jerrid Kruse Jan 2010

When Dissatisfaction Is A Good Thing, Michael P. Clough, Jerrid Kruse

Iowa Science Teachers Journal

Our previous editorial (Clough and Kruse, 2010) in the Iowa Science Teacher Journal used conceptual change theory (Posner, 1982; Pintrich et al., 1993; Abd-El-Khalick & Akerson, 2004; Clough, 2006) to highlight the similarities between students learning science content and educators learning to teach well. An important part of conceptual change is first acknowledging and then confronting current ways of thinking. That is, before learners (whether children or adults) will consider altering their thinking, they must first develop some sense of dissatisfaction with their currently held ideas. That can be difficult because the ideas people hold do appear to work — …


Temperature Rising: Investigating Rates Of Temperature Change, Jacob Norlin, Daryl Miller Jan 2010

Temperature Rising: Investigating Rates Of Temperature Change, Jacob Norlin, Daryl Miller

Iowa Science Teachers Journal

This exploratory activity, designed for secondary physical science or earth science students, investigates rates of temperature change over bodies of water and land. Students discuss temperature trends of several cities across the United States, which creates an opportunity to conduct classroom experiments to explain these trends. Students write procedures and generate data of temperature changes between areas of water and land. Students gain a valuable, concrete experience of temperature changes which in turn enables them to better understand and explain why similar cities experience vastly different temperature patterns. This activity can then serve as a basis to address the abstract …


Confronting Doubts About The Intelligibility, Plausibility, And Fruitfulness Of Inquiry-Based Instruction, Jerrid Kruse, Michael P. Clough Jan 2010

Confronting Doubts About The Intelligibility, Plausibility, And Fruitfulness Of Inquiry-Based Instruction, Jerrid Kruse, Michael P. Clough

Iowa Science Teachers Journal

Our two prior ISTJ editorials in the Iowa Science Teacher Journal (Clough & Kruse, 2010a & 2010b) have applied a conceptual change framework (Posner, Strike, Hewson & Gertzog, 1983; Pintrich et al., 1993; Abd-El-Khalick & Akerson, 2004; Clough, 2006a) to understand the difficulties students have in abandoning their intuitive ideas about the natural world and, for the same reasons, the difficulties teachers have in jettisoning their intuitive and learning. Our last editorial noted that in both cases, dissatisfaction with prior ways of thinking must be achieved before alternative ways of thinking will be seriously sought and considered. To initiate a …


Pulling Students In: Creating Concrete Experiences Through A Simple Pulley Device, Joe Kohlhaas, Teresa Morales Jan 2010

Pulling Students In: Creating Concrete Experiences Through A Simple Pulley Device, Joe Kohlhaas, Teresa Morales

Iowa Science Teachers Journal

Physics is often taught with an emphasis on mathematical relationships. Many teachers use equations to teach, assuming that the content will fall into place. In reality, all students benefit from concrete representations and familiar objects and properties before learning abstractions (Karplus, 1977). Since mathematics is inherently abstract it must be reserved until after students have a firm conceptual understanding. This article provides a concrete activity that encourages students to explore pulleys. This activity promotes National Science Education Content Standards A, B, E, and F. It also addresses Iowa Teaching Standards 1, 2, 3, 4, and 5.


How Does Water Become Polluted? Helping Elementary Students Learn How To Prevent Pollution, Kelsey Bentzinger, Lindsey Thilges, Ken Vacek Jan 2010

How Does Water Become Polluted? Helping Elementary Students Learn How To Prevent Pollution, Kelsey Bentzinger, Lindsey Thilges, Ken Vacek

Iowa Science Teachers Journal

Through making observations of mixing various items with water, students develop ideas about how pollution happens. The cumulative effect of what happens when many people add only “a little something” to the water provides students with a concrete representation of what can happen in their own communities. Students complete the lesson by determining what they can do to prevent pollution from happening in their own communities. This activity promotes National Science Education Content Standards A, B, and F, and Iowa Teaching Standards 1, 2, 3, 4, 5, and 6.
