Prospective Teachers’ Ability To Pose Word Problems, Nusrat Fatima Rizvi
Institute for Educational Development, Karachi
The purpose of this study was to assess difference in prospective teachers’ ability to pose word problems for mathematical expressions involving division before and after an instruction intervention. After the initial assessment of participants’ ability to pose word problems for division expressions, the researcher introduced an alternative model i.e. rate or ratio to represent division involving whole numbers. After the intervention it was assessed whether the model helped the prospective teachers develop word problems for division of fractions. The findings revealed that the prospective teachers successfully posed word problems for division of whole numbers based on intuitive model of fair …

Helping Children To Understand Particulate Nature Of Matter, Muhammad Riaz
Institute for Educational Development, Karachi
Whenever I taught about the particulate nature of matter in solids, liquids and gases, I often had difficulty explaining this abstract concept to my students. The students, in turn, had much difficulty conceptualizing the structure and behavior of the particles, which ultimately led to difficulties in understanding the complex configuration of particles in matter at various levels. This article focuses on studies that reveal students’ alternative frameworks for the particulate nature of matter in solids, liquids and gases. Also, I suggest factors that contribute to these alternative frameworks, incorporating my own experiences in developing an understanding of this concept. Finally, …
