  1. Hypothesis: implementing project based collaborative group learning in the classroom is preferred by students as opposed to traditional instruction. In addition, it improves the social skills, relationships and class cohesion of students in the class by providing them with experiences that require the practice of communication, cooperation, collaboration, and compromise . Project Based Cooperative Group Learning in Social Studies and its Effect on Students’ Social Skills, Class Cohesion and learning Preferences CBSE 7202NET Linda Savdie Fall 2013 Research 2

  2. Research Design • Pre-experimental design with one group that receives treatment and no control group. • One-group pretest - posttest design (OXO). • No random sampling. • The sample, (N = 22) third grade boys from a Brooklyn Yeshivah, have been given a survey (pretest- O) to fill out prior to the implementation of collaborative group projects (treatment – X). After the implementation of the group projects, students took the same survey to measure any changes (posttest- O).

  3. Rationale for Research Design • Due to limitations in time and the length of the social studies units, only two tests could be administered with the treatment implemented after the first test. • Due to limitations in access to students, small size of the school, and the presence of gender separated classes, only one class could be utilized. This prevented the use of a larger sample and/or control group.

  4. Internal Threats to Validity • History: It is likely that an event can occur that affects the results of the test due to the sample consisting of 22 boys who live in the same area, attend the same school and have known each other for a while. • Maturation: The sample consists entirely of young boys. Children change and mature more rapidly than adults and that can affect the results of the tests. • Pre-test sensitization: After administering a pretest, students will already be exposed to the content of the research. This may affect the results of the posttest. • Instrumentation: The validity of the survey created for this study is unknown. • Statistical regression of the mean: may affect the posttest if a student scores very high or very low on any of the scales. Statistically, that student will most likely retest at score that is closer than the mean.

  5. External Threats to Validity • Selection–treatment interaction: because the sample consists of 22 students with virtually identical demographics, the generalizability of research is very limited. • Pretest treatment: The students may react differently to the treatment because of the pretest. • Novelty effect: the independent variable, cooperative group projects, is not something that is utilized often in this third grade classroom.

  6. Proposed Data & AnalysisPosttest Social Skills Compared to Pretest Comparing the pre-test and post-test scores of the proposed data shows that the intervention, project based collaborative group learning, had a positive effect on students’ social skill scores. Tables, graphs, and mean calculation done in Microsoft Excel.

  7. Proposed Data & AnalysisPosttest Preference for Group Work Compared to Pretest Comparing the pre-test and post-test scores of the proposed data shows that the intervention, project based collaborative group learning, had a positive effect on students’ preference for group work. Tables, graphs, and mean calculation done in Microsoft Excel.

  8. Proposed Data & AnalysisPosttest Perceived Class Cohesion Compared to Pretest Comparing the pre-test and post-test scores of the proposed data shows that the intervention, project based collaborative group learning, had a positive effect on students’ perceived class cohesion. Tables, graphs, and mean calculation done in Microsoft Excel.

  9. Posttest CorrelationsSocial Skills and Preference for Group Work Correlation Coefficient: 0.6797rxy It is proposed that there will be a strong positive correlation between the Post-test scores of Social Skills and Preference for Group Work. Tables, graphs and correlation calculation done using Microsoft Excel.

  10. Posttest CorrelationsSocial Skills and Survey Question “How many friends do you have in the class?” Correlation Coefficient: 0.3064rxy It is proposed that there will be a fair positive correlation between the Post-test scores of Social Skills and students’ response to survey question “How many friends do you have in class?”. Tables, graphs and correlation calculation done using Microsoft Excel.
