TIFRAC, India’s first computer — A retrospective

To be associated with an important and challenging activity that is being carried out for the first time in the country is a truly memorable and satisfying, even if somewhat disquieting experience. I was privileged enough to have this opportunity when I was involved in the design and implementation of India’s first computer. TIFRAC (Tata Institute of Fundamental Research Automatic Calculator) — so was it named by Jawaharlal Nehru when it was formally commissioned in 1960 — was a truly a unique computer. Some of the features of this machine are described later in this article. It is also my intention in this article to convey some of the excitement, adventure and sense of accomplishment that the successful completion of this exercise brought to the design team.     

Mathematics teaching during the early years in Hong Kong: a reflection of constructivism with Chinese characteristics?

This paper characterizes early mathematics instruction in Hong Kong. The teaching of addition in three pre‐primary and three lower primary schools was observed and nine teachers were interviewed about their beliefs about early mathematics teaching. A child‐centered, play‐based approach was evident but teachers emphasized discipline, diligence and academic success. Observations also revealed practices reflective of both constructivist and instructivist pedagogies. Results from interviews suggest that teachers' traditional cultural beliefs about instruction were challenged by western ideologies introduced in continuing professional development courses and by notions promulgated by the educational reforms. Both consistencies and inconsistencies between teachers' beliefs and practices were identified. Implications of the findings are discussed.
