Four experiments tested three to six year olds' and adults' understanding of animals' growth changes. All subjects understood that animals get larger with age. Older children and adults, but not younger children, allowed for dramatic changes in the size and shape of animals over the animals' lifespans. (BC)

Serial data for 268 normal boys and girls were obtained and used to calculate predicted adult statures without using skeletal age. The data can be used to measure physical maturity in 5- to 15-year-old boys and 3- to 13-year-old girls without invasion of privacy or radiological techniques. (Author/PP)

This study was designed to determine whether chronological age, the number of permanent teeth erupted, or the combination of the two would predict a child's readiness for formal arithmetic work. Sixty-four children were randomly chosen and three phases of testing conducted. The findings did not support the use of the number of teeth erupted as a…

An abundance of research relative to physical fitness and, more generally, physical education of school children, has surfaced during the past few years. Negative aspects of health and physical fitness are increasing year by year, and further evidence suggests that academic performance is negatively affected by low levels of fitness. A survey was…

The physical fitness and lifestyle of Canadian school children has been deteriorating in recent years.
