This history of computers in education covers two continents. By analysing the experiences of two people a set of turning points in history is identified. These turning points are in the experienced history and so indicate the impact of changes on the citizens of two countries.

Turning points and transitions are both life events marked by significant change. Whereas turning points are personal changes in life direction, transitions are external changes in daily circumstances. Transition-linked turning points are events that fit both of these definitions. Although transitions and turning points have been examined separately, the current study is the first empirical com...

Piecewise growth curvemodel (PGCM) is often usedwhen the underlying growth process is not linear and is hypothesized to consist of phasic developments connected by turning points (or knots or change points). When fitting a PGCM, the conventional practice is to specify turning points a priori. However, the true turning points are often unknown and misspecifications of turning points may occur. T...
