A thesis emphasizes research to a higher degree of academic achievement whereas dissertation denotes detailed references combined with observations made by the author, often at the graduation level. Both are research oriented activities, with thesis leading to the attainment of a doctorate or PhD degree while a dissertation culminates in a post graduate degree like MPhil. The reverse could apply in American universities, thereby adding to the confusion, with a dissertation leading to a PhD and a thesis produced while enrolled in a Master's program.
Because your abstract will be published in Masters Abstracts International or in Dissertation Abstracts International , please write and proofread it carefully. When possible, avoid including symbols or foreign words in your abstract, as they cannot be indexed or searched. Avoid mathematical formulas, diagrams, and other illustrative materials in the abstract. Offer a brief description of your thesis or dissertation and a concise summary of its conclusions. Be sure to describe the subject and focus of your work with clear details and avoid including lengthy explanations or opinions.
