This article has three main purposes. The first is to provide a historically and theoretically based critique of the topic of number learning in early childhood mathematics, thereby establishing the need for a systematic review in this field. The second is to outline the results of constructivist research in number learning and related Australian research. Finally, specific proposals are made for rethinking and changing cur-riculum emphases in the teaching of number and for the establishment of ongoing research programs in early child-hood mathematics. First it will be argued that the approaches to number topics in current Australian curricula in early childhood mathematics have resulted from British and United States influences since around 1960, with British influences domi-nating in the first half of the last 30 years (1960-75) and

This paper investigated teachers ’ perception of examination malpractices among secondary school students in Ondo State, Nigeria. As a descriptive research, the study population comprised the 481 secondary schools in Ondo State, Nigeria. This was made up of 281 public and 200 private schools as well as 210 urban and 272 rural schools. The sample consisted of 245 schools made up of 142 public and 103 private schools. Out of the 142 public schools, 62 were urban while 80 were rural schools. Out of the 103 private schools, 47 were urban while 56 were rural schools. Out of the 4250 teachers in the schools, 960 teachers were selected. The methods of selection were also by multi-stage and stratified random sampling techniques. The instrument used to collect data was a questionnaire while the data collected were analyzed using percentages, Person r product moment correlation and the t-test. The findings revealed that one major cause of examination malpractices in the schools was indiscipline among students that made many of them to be involved in examination malpractices. Other important causes include the non-implementation of the examination malpractices decree and the lack of effective supervision of students during examinations. It was recommended that concerted efforts should be made at improving the level of discipline among students through counseling services in the schools. There should be the full implementation of the examination malpractices decree. There should be increased efforts at effective supervision of students during examinations. The termination of appointment of examination officials and teachers involved in perpetrating examination malpractices should be in force to serve as a deterrent to others.

An efficient algorithmic solution to the classical five-point relative pose problem is presented. The problem is to find the possible solutions for relative camera pose between two calibrated views given five corresponding points. The algorithm consists of computing the coefficients of a tenth
