Using a concept test given prior to the lecture unit, and after, the difference in scores is used to recognize if the concepts presented have actually been comprehended. Used specifically in a lecture unit on solubility and solutions, the concept test tested student’s knowledge of supersaturated, saturated, and unsaturated solutions. With a visual identification and a written explanation, the student’s ability to identify and explain the three solutions was tested.
In order to determine the cause of the change in score from pre- to post-test, an analysis of the change in scores and the effects of question type and solution type was conducted. The significant results are as follows:
The change in score from pre- to post-test was found to be significant, with the only difference between the two tests being the lecture unit and intervention
From pre- to post-test, solution type had a significant effect on the score, with the unsaturated solution being the most easily recognized and explained solution type
Students that felt that the YouTube videos greatly increased their concept comprehension, on average, performed better than their counterparts and also saw a greater increase their score from pre- to post-test
The purpose of this study was to bring new information to the field of education research on<br/>graduation rates and school programming. Research on graduation rates and the effects of school<br/>programs exist, however there is not an abundance of research aimed specifically at Title I high<br/>schools. The goal was to find what school characteristics might impact graduation rates in this<br/>population. The thesis focused on Title I high schools in the Phoenix Union District with a<br/>graduating 2019 class of at least 250 students. This limited the effect of variability (school size,<br/>location, socioeconomic status). To research this topic, school characteristics were selected<br/>including course rigor, mentor programs, and college prep programs, as well as specific schools.<br/>To obtain the information, multiple sources were used including the Arizona Department of<br/>Education website, school websites, and school administrators/staff. The research revealed that<br/>the effect of course rigor, college prep programs, and mentorship on graduation rates in Phoenix<br/>Union High Schools is not apparent. Further research should be conducted into other possible<br/>causes for the gaps in graduation rates between the Title I high schools in this district. Future<br/>research on ELL students and programs in the Phoenix Union district and their effectiveness or<br/>lack thereof is also recommended. The research shows that this large demographic negatively<br/>correlates with the overall graduation rates at the six schools researched.
This thesis attempts to explain Everettian quantum mechanics from the ground up, such that those with little to no experience in quantum physics can understand it. First, we introduce the history of quantum theory, and some concepts that make up the framework of quantum physics. Through these concepts, we reveal why interpretations are necessary to map the quantum world onto our classical world. We then introduce the Copenhagen interpretation, and how many-worlds differs from it. From there, we dive into the concepts of entanglement and decoherence, explaining how worlds branch in an Everettian universe, and how an Everettian universe can appear as our classical observed world. From there, we attempt to answer common questions about many-worlds and discuss whether there are philosophical ramifications to believing such a theory. Finally, we look at whether the many-worlds interpretation can be proven, and why one might choose to believe it.
