THE USE OF GROUP WORK IN IMPROVING PUPILS’ PARTICIPATION DURING MATHEMATICS LESSONS By Amy Lau Mee Ling <amylau87@yahoo.com> ABSTRACT Group learning is a kind of social interaction where the pupils can learn from their peers. From my experience‚ pupils seldom involved themselves with each other in learning Mathematics. Therefore‚ I pursue a research that can help me to increase my Year 3 Kemboja pupils’ involvement in learning Mathematics by doing group work. The respondents

that is located in Group 13 or the “Boron Group” on the periodic table of the elements. It has the chemical symbol Ga and has an atomic number of 31 meaning it has 31 protons and 31 electrons. The atomic mass of Gallium is 69 meaning it has 38 neutrons. Gallium is a transition metal and was discovered in 1875 by French Chemist Paul Emile Lecoq de Boisbaudran after the element was predicted by Dmitri Mendeleev who created the periodic table of the elements in the 1860s. Boisbaudran named Gallium after
