Research and Evaluation essays The article containing the hypothesis used by the research study this paper will discuss is the Teachers' Gestures Facilitate Students' Learning: A Lesson in Symmetry, authored by Valenzeno, Alibali, and Klatzky. The research study, on the other hand, has a document title of Understanding Change in Mathematical Reasoning: Evidence from Speech and Gesture, Valenzeno, Alibali, and Klatzky's article hypothesized that teacher's gestures, as accompanied by speech, enables students to improve comprehension skills and learning abilities. They explained that gestures are forms of abstract that provide supplementary information to students. Through pointing to objects or making hand motions relevant to what is currently being spoken, students can develop association of information Based from the results of a conducted experiment by Valenzeno, Alibali, and Klatzky, they came up with the hypothesis that gestures facilitate students' learning. They carried out an experiment where children are asked to view two types of videotaped lecture on symmetry. The first type shows an explanation using speech and gesture, while the second type shows an explanation using speech alone. After viewing the videotapes, Valenzeno, Alibali, and Klatzky found that the children who viewed the speech-and- gesture lecture showed more understanding on symmetry and asymmetry. Valenzeno, Alibali, and Klatzky's hypothesis was used in Martha Alibali's research study. Martha Alibali's paper aims to provide evidences and inferences from written articles and studies on the effectiveness of applying gestures in speech while conveying Martha Alibali used a number of references to validate her study, and one of the references she used is Valenzeno et.al's article. Her study aims to investigate the effects of using non-verbal communication with verbal ...
