Southern bottomland sites are among the most productive areas for producing high quality grade hardwood, yet the ability to estimate the quantity and quality of standing grade hardwood is almost non-existent. Measurements and observed log grades were recorded on standing trees to construct volume prediction models for individual trees. Several different modeling techniques were explored and compared during development. Developed equations predict merchantable sawtimber volume and volume by grade category in trees by species group. Two separate sets of equations were developed for each species group using either total height or merchantable height. Models were chosen based on significance of variables, index of fit, RMSE, bias, ease of use, and biological trends. The models developed to predict merchantable sawtimber and grade volumes were designed to be implemented in a larger hardwood growth and yield system.

In addition to the ever-changing demands of the workforce and student demands, the community college must address how performance and withdrawal are affected by traditional classroom instructional delivery and the inclusion of alternate instructional delivery settings such as internet-based approaches in courses. This quantitative study was conducted to provide evidence-based research to a community college in Northeast Tennessee. Specifically, this research study focused on an important aspect of instructional course delivery methods: What are the relationships between traditional classroom and internet-based course instructional delivery methods in relation to withdrawal and grade-distribution patterns for specified courses (English 1010, Math 1710, Biology 2010, and Business CSCI 1100) at a community college in Northeast Tennessee? Course instructional delivery practice is expensive, regardless of the course delivery method. The community college officials wish to best use their resources and instructional delivery practices. Student withdrawals have a significant effect on the fiscal stability of an institution of higher education. Reducing the number of students who withdraw from a course is instrumental to positive financial health and educational program practices. In this quantitative study, data were gathered through a method of secondary analysis by a community college in Northeast Tennessee and distributed to the researcher for compilation and statistical analysis. Independent samples t tests were used to evaluate whether the mean grade point average and percentage of students withdrawing in English 1010, Math 1710, Biology 2010, and Business CSCI 1100 differed between traditional classroom course sections and internet-based course sections taught in the same academic period. Findings from this study indicated that instructional delivery method does not significantly influence mean grade point averages, and students tend to perform consistently regardless of the instructional delivery setting; however, percentage of student withdrawals vary between instructional delivery methods with the analysis of Biology 2010 finding that traditional classroom course sections had higher withdrawals than did the internet-based course sections.

Syftet med denna studie är att bidra med ny kunskap om svenska gymnasieelevers betygsfördelning och betygsutveckling i ämnet Dansteknik. Studien omfattar en totalundersökning av avgångsbetygen för de 414 gymnasieelever som avslutat sina studier vid det estetiska programmets dansinriktning i Stockholms stad under åren 2014 - 2018. Elevernas betygsfördelningar i olika kurser i ämnet Dansteknik samt deras betygsutveckling över kurserna har analyserats statistiskt. Studien visar att eleverna har höga betyg i ämnet Dansteknik, dels i relation till elevernas betyg i övriga ämnen men även i relation till riksnivåerna för andra ämnen, kurser och elevers avgångsbetyg generellt. Studien visar också att elever i hög grad behåller en liknande betygsnivå i Dansteknik under hela utbildningen samt att elevers och gymnasieskolors val av kurser i ämnet Dansteknik påverkar elevernas betygsutveckling och med stor sannolikhet även deras kunskapsutveckling i ämnet. / The purpose of this study is to contribute with new knowledge about grade distribution and students’ subsequent grades in the subject Dance technique as part of Swedish upper secondary education. The study encompasses the upper secondary school grades of the 414 students that ended the Arts Programme in dance in the City of Stockholm, Sweden, during the years 2014 - 2018. The results are based on a statistical analysis of these students’ course grades in the subject Dance technique. The study shows that students have generally received high grades in the subject Dance technique, both in relation to their grades in other subjects as well as in relation to national grade averages in various courses and subjects. The study also shows that the students maintain a somewhat even grade level throughout their education and that students’ grade level and learning in Dance technique is affected by students’ and schools’ course choices in the subject.
