The Blue Wave classroom diner serves breakfast and math skills, and fourth graders are having a great time with it at Inter-Lakes Elementary School. Hands on learning has come to fourth graders in a delicious way.  In Steve Watson's class, students are cooking breakfast for others to make practical use of their math skills. They've opened up a classroom diner and call it The Blue Wave Diner. They had family members visit one morning for breakfast.  They served omlettes, sausage, pancakes, and home fries. “This is a year-long project that we are doing,” said Watson. “These are my math students, and earlier in the school year, we met and talked about different ways to work on math skills. This is different ways of learning fractions, adding and subtracting. These kids really wanted to try some cooking.” How has the class diner helped with math skills?  Students have done the shopping, the measuring, the cooking, all together as a class.  The...

Have you ever wondered why you need to learn science in elementary school? Many students wonder why they need to learn it so early in life. Others just fail to understand the importance of including it in the school years. Science offers the answers to various questions we ask out of curiosity, in our early years. For instance, how does it rain? How does our body function? and many more. Science is just as important as learning other subjects like mathematics and history. Because the subject is so vast, learning the basics right from your early learning days will enable you to decide whether you want to pursue a higher education in the subject. Here we discuss some important aspects in our lives that are covered by this subject. Develops problem-solving skills   With the knowledge of science, you learn to think logically and solve a problem. It is this problem-solving skill, which is learnt in the early years that have enables a person to solve problems. Co...

Less  interest in five students to submit their assignment R. P. Kalupahanage 1 , Dr. Sunethra Karunaratne 2 1. Wickramabahu National College, Gampola, Sri Lanka 2. Faculty of Science , University of Peradeniya, Sri Lanka Abstract Action research was on chosen five students in grade 10-D who seemed to have less interest in submitting their assignments. The issue led me to investigate to find out the reason for their non participation. As the first action a home assignment was given to the whole class with a complete information sheet, which included the criteria for marking and a reminder note about the submission date was hung effectively at eye level in the classroom. Students were expected to work independently and complete the assignment within a three weeks time. As the second action students in the classroom were grouped randomly and an interesting group assignment was given. This was expected to complete by the students as a group work in the clas...

LADY BLAKE THE PLACE OF SERENITY   R. P. Kalupahanage 1 , J. C. K. Ekanayake 1 , D. D. R. Kumari 1 , C. S. Wimalaratne 1 and                  S. Karunaratne 2 1 Postgraduate Institute of Science, University Peradeniya, SRI LANKA 2 Faculty of science, University Peradeniya, SRI LANKA The aim of this study was to learn qualitative research methods by observing “what was happening” in the social institute. The Lady Blake Nunnery was selected for this study considering accessibility, availability and acceptability and a teacher should also be aware with inclusive education. The observations were gathered forty hours at different times and using formal, informal and semi structured interviews. Analyzing data gathered from these sources through triangulation and ground theory found that the institute was trying its best to reach their vision of reliving all beings through the teaching of a lord Buddha. To reach this they sp...
