In a recent study, researchers found that students who studied in groups scored higher on mathematics exams compared to those who studied alone. Based on this finding, the researchers concluded that studying in groups improves students' mathematics performance.
However, this conclusion may be flawed due to a lack of sufficient evidence considering other influencing factors such as the quality of study materials used, the prior knowledge of the students, and the dynamics of group interactions. To strengthen their argument, the researchers should consider evidence that...
