onclusions that might reasonably be drawn from the results. At the beginning of the school year, fifth graders in two different classes at two different schools are, on average, quite similar in their knowledge and skills in mathematics. In the first 2 weeks of the year, they use a computer software program that teaches them how to add, subtract, multiply, and divide fractions. Students progress at their own pace through the program, tackling many practice problems and getting immediate feedback about their solutions. Students in one class use Version A of the program, in which they get feedback about all of their responses. Students in the other class use Version B, in which they get feedback about only half of their responses. The students who use Version A le
As you read about each study, (a) classify the type of research that it reflects, and (b) identify the kinds of conclusions that might reasonably be drawn from the results.

Students in one class use Version A of the program, in which they get feedback about all of their responses. Students in the other class use Version B, in which they get feedback about only half of their responses. The students who use Version A learn how to work with fractions more quickly than do students who use Version B.
(a) Classify the research as one of the following:
Quantitative/descriptive
Quantitative/
Quantitative/experimental
Quantitative/quasi-experimental
Qualitative
Mixed methods, and then
(b) Identify one or more conclusions that might reasonably be drawn from this study and, if relevant, one or more conclusions that cannot be drawn from the study.
