4. Abstract: One Paragraph Including Purpose or Rationale of the StudyPurpose or Rationale of the Study –Provides background –Identifies the question or hypothesis –Explains why the study was done MethodologyMethodology –Identifies the major experimental approach –Explains how the study was done ResultsResults –Summarizes the major findings –Shows what was found ConclusionConclusion –Briefly explains what the results mean –Relates to other findings in the field of study

5. Introduction Includes Background for the question to be studied, from general to more specificBackground for the question to be studied, from general to more specific –Explains what is known –Identifies what is not yet known Statement of the hypothesis that will be testedStatement of the hypothesis that will be tested –Identifies the question that the researchers asked and answered –Emphasizes how the current experiments add to further understanding in the field of study

6. Materials and Methods Includes Description of the Experimental ProceduresDescription of the Experimental Procedures –Provides sufficient detail for replicating the method –May refer to other published protocols Identification of Sources of Unique MaterialsIdentification of Sources of Unique Materials

7. Results: Data Presentation Includes Description of the experimental outcomes, making reference to the data that is presentedDescription of the experimental outcomes, making reference to the data that is presented –Introduces the order in which the data is presented –May emphasize what the reader should notice about the data Tables and Figures showing the experimental outcomesTables and Figures showing the experimental outcomes –Each has a caption describing its contents –Combination of Caption + Figure or Table needs to tell a complete story

13. Strategies for Reading Primary Literature Use Title + Abstract to see a broad overviewUse Title + Abstract to see a broad overview –Consider what you already know about the field –Skim or skip the Introduction if you already have background for understanding the research Use Figures and Tables to identify the major findingsUse Figures and Tables to identify the major findings Consult the Discussion to understand the significance the authors assign to their findingsConsult the Discussion to understand the significance the authors assign to their findings Delve into the Materials and Methods if needed for understanding the figures or as a basis for designing your own experimentsDelve into the Materials and Methods if needed for understanding the figures or as a basis for designing your own experiments
