Effects Of Stepwise Guided Inquiry On Students' Attitudes And Depth Of Knowledge From Written Lab Reflections In High School Chemistry, Melissa Rae Campbell Johnson

Graduate Research Papers

Many teachers find it challenging to embed guided inquiry into high school chemistry courses. Although guided inquiry provides excellent opportunities for students to engage in data analysis, misconceptions and loss of class time are teacher stated problems with guided inquiry. A stepwise inquiry project can slowly introduce students to the inquiry process of data analysis in high school chemistry.

This stepwise inquiry project examined three different inquiry labs designed around the anchoring phenomenon, “ Which toothpaste protects our teeth the best?”Each lab progressed in inquiry level. Lab one was written at inquiry level one,confirmation. The second lab was written at …

Accuracy Of Self-Assessment In A Ninth Grade Earth Science Classroom, Alyssa Jacobson

Graduate Research Papers

Student engagement is a constant struggle teachers and schools work to address. Students who are not engaged are more likely to drop out of school and participate in risky behaviors that negatively impact themselves and society as a whole. As a means to combat student disengagement, school districts have begun to implement The New Art and Science of Teaching, a framework meant to engage students by involving them in the learning process through self-assessment.

The purpose of this study is to determine how accurately high school aged students can self-assess and how students make decisions when they self-assess. To …

Analysis Of Assessments On Secondary Students' Development And Interpretation Of Models, Alaina L. Appley

Graduate Research Papers

As districts are making the shift to three-dimensional learning the development of a coherent set of high-quality task-based assessments has been a challenge. For this research I collected and analyzed twelve of my district's assessments over the scientific skill of modeling from grades seven through 12. The analysis involved two tools developed by NGSS and Achieve.org to determine the extent to which the assessments ask students to perform tasks that are driven by phenomena and use the three-dimensional in service of sense-making, the Task Screener and the Framework to Evaluate Cognitive Complexity in Science Assessments. The findings support what …

Immediate Vs. Deferred Feedback During Formative Assessments In A 9th Grade Physical Science Course, Jordan Sonntag

Graduate Research Papers

For educators, feedback has become a very important part of the teaching practice that is taught in both teacher education programs and building-level professional development. While many studies have been done on feedback itself, there is much less research on the effectiveness of certain types of feedback used within a Learning Management System (LMS). The goal of this experiment is to determine if there is any difference on summative assessment scores based on the use of different types of feedback on formative assessments using an LMS.

An LMS is a program that allows the educator to create step by step …

How To Create A Radically Inclusive Math Classroom With Regards To Gender And Sexual Orientation, Alexa Devore

Honors Program Theses

An extensive literature review was conducted to analyze how a secondary mathematics teacher can best support female and LGBTQ students. While extensive research has been conducted about the gender gap in STEM, concerning female students, little research has been done that includes LGBTQ students. While female students have made great improvements in mathematics participation and achievement, there is still work to be done. LGBTQ students face similar difficulties as female students but have not received the same attention and research as female students. This research indicates there are more things teachers should be doing to support students who have been …

Summer Undergraduate Research Program (SURP) Symposium

Since the Next Generation Science Standards (NGSS) have been adopted by Iowa, the changing expectations for high school physics students means that preexisting curricula like PRISMS PLUS need to be brought into alignment with the NGSS. Before revising PRISMS PLUS, other aligned curricula were consulted, as well as many sources of physics education research. A revised PRISMS PLUS template aligned with the NGSS and physics education research was made, which can be applied to each of the learning cycles in PRISMS PLUS. One learning cycle was revised in full, as an example.

Development Of Curriculum For Next Generation Science Standards In High School Chemistry, Jennifer L. Brown

Graduate Research Papers

The aim of this project is to develop a unit relevant to students, aligned with three-dimensional performance expectations, and beneficial to teachers in helping students to meet those standards. To effectively meet those goals, an understanding of what curriculum is and how to develop it is needed. Curriculum is “the high-quality delivery system for ensuring that all students achieve the desired end – the attainment of their desired grade- or course-specific standards” (Ainsworth, 2010, p. 4). Without a clear goal for student performance and a detailed plan for how to get them there, lasting, meaningful learning is not likely to …

A Qualitative Comparison Of General Chemistry And Advanced Placement Chemistry Students' Misconceptions Regarding Solution Chemistry, Megan J. Vandersee

Dissertations and Theses @ UNI

This study focused on identifying misconceptions which high school AP and collegiate general chemistry students hold with regards to solution chemistry topics and comparing the misconceptions held by each student group. Previous research has found that misconceptions can greatly impact students’ understanding of material and have a negative impact on student learning. However, not all solution chemistry topics had been explored in previous research. In addition, it has been suggested that collegiate students have reached a higher level of cognitive development as they are older and more advanced in their studies. If this is the case, one could assume that …

Incorporating The Ti-92 Into A High School Classroom, Heather Golliher

Presidential Scholars Theses (1990 – 2006)

Calculators have been a part of mathematics for years. More recently, the graphing calculator has been widely accepted as a mathematical tool. The Tl-92 has the capability to take this technology integration a step further. It has been described as having "the power of a computer with the independence of a graphing calculator." With the geometry package and the symbolic manipulation unique to the Tl-92, the question becomes, how should this technology be coordinated with the existing curricula in high school classrooms to make the learning and teaching of mathematics as exciting and relevant as possible?
