- purposes of a thorough review of the literature
-
1) delimiting the research problem
2) seeking new lines of inquiry
3) avoiding fruitless approaches
4) gaining methodological insights
5) indentifying recommendations for further research
6) seeking support for grounded theory - primary source
- a document that was written by the individuals who actually conducted the research study or who formulated the theory or opinions that are described in the document
- CIJE
- Current Index to Journals in Education indexes articles in many hundreds of education-related journals (ERIC)
- RIE
- Reseources in Education indexes various non-journal documents. (ERIC)

~ Vote Counting ~
~ Chi-Square Method ~
~ Meta-Analysis ~ - narrative review
- emphasized better-designed studies, organized their results to form a composite picture of the state of knowledge on the problem or topic being reviewd, statistically significant results may have been noted, each study may have been described separetely in a few sentences or a paragraph
- vote counting
- enables the reviewer to test the statistical significance of this trend of results across studies
- chi-square
- involves first converting whatever inferential statistics are reported in each study into exact probability values
- advantages of meta-analysis
-
1) it focuses on the magnitude of effect observed in each study
2) provides a metric (effect size) that can be applied to any statistic and any measure
3) allows the reviewer to determine whether certain features of the studies included in the review affected the results that were obtained
