Matthew Jon Balcom – ProQuest LLC, 2023
The American school system is funded, operated, and evaluated based on student academic achievement data that is generated by various assessment tools and grading practices. The most traditional grading practice, norm-referenced grading, assesses student academic achievement on a 100-point scale that is further broken into categorical levels (A-F)…

Joe Olsen – ProQuest LLC, 2023
Instructional explanations are an ubiquitous component of classroom instruction, but are relatively neglected in science education when compared to other facets of teaching and learning. The ubiquity of instructional explanations and their potential to stimulate learning in students suggests that they should garner more attention from science…

Ziegler, Brittany Ann – ProQuest LLC, 2012
Historically, students have been viewed as empty vessels and passive participants in the learning process but students actually are active forming their own conceptions. One way student learning is impacted is through assessment. Alternative assessment, which contrasts traditional assessment methods, takes into account how students learn by…

Lapainis, Theodore E. – ProQuest LLC, 2009
Understanding the functioning of the brain is hindered by a lack of knowledge of the full complement of neurotransmitters and neuromodulatory compounds. Single cell measurements aid in the discovery of neurotransmitters used by small subsets of neurons that would be diluted below detection limits or masked by ubiquitous compounds when working with…

Pongsanon, Khemmawadee – ProQuest LLC, 2012
Although teacher educators have successfully helped K-12 teachers' develop adequate views of NOS, their views have not been transferred to their students. It is evident that K-12 students' understanding of NOS still does not align with the recommendation of the reforms document, indicating that holding an adequate view of NOS is…
