The purpose of the thesis is to examine a selection of papyri from the large corpus of Euripides, Sophocles and Aristophanes. The study of the texts has been divided into three major chapters where each one of the selected papyri is first reproduced and then discussed. The transcription follows the original publication whereas any possible textual improvement is included in the commentary. The commentary also contains a general description of the papyrus (date, layout and content) as well reference to special characteristics. The structure of the commentary is not identical for marginalia and hypomnemata: the former are examined in relation to their position round the main text and are treated both as individual notes and as a group conveying the annotator's aims. The latter are examined lemma by lemma with more emphasis upon their origins and later appearances in scholia and lexica. After the study of the papyri follows an essay which summarizes the results and tries to incorporate them into the wider context of the history of the text of each author and the scholarly attention that this received by the Alexandrian scholars or later grammarians. The main effort is to place each papyrus into one of the various stages that scholarly exegesis passed especially in late antiquity. Special treatment has been given to P.Wurzburg 1, the importance of which made it necessary that it occupies a chapter by itself. The last chapter of the thesis deals with the issue of glosses, namely their origin and use in the margins of papyri. The focus is again on the history of early collections of tragic and comic vocabulary and their appearance in the margins or hypomnemata. The parallel circulation of hypomnemata and glossaries often compiled by the same people and some special features of the glosses in our material led to the conclusion that most glosses at least in the earlier periods were copied from hypomnemata. The thesis ends with a presentation of all conclusions from the previous chapters in relation to the history of scholarship and book production in late antiquity

This Study examines the grades of students using study skill methods and those who do not. The experiment consists of giving the treatment group the opportunity to use well- known study techniques. The Control group could only read the material. Both groups were given ten minutes to read a pre-selected text. The text consisted of an 1,807 word lesson on the, "Technical Training Management System." Each group was given five minutes to take a twenty item quiz. Fifty-five students in the control group were limited to only reading the material. Fifty-six students in the treatment group could choose between highlighting, note-taking, and underlining. The results of the test scores were compared using a t - test for dependent samples. One week later, the same students in each group were re-tested, using the same quiz they had taken earlier. Students had five minutes to review study material. Study material for the treatment group included the same material they had annotated earlier. The Results from each group wascompared. Efforts were made to avoid potential flaws in previous studies, thereby producing more viable results. Results of this study indicate there is no significant difference between the grades of students who use the aforementioned forms of text annotation and those who do not.
