Abstrak	:	The present study of gifted students’ views of assessment is aimed at understanding how the employment of Embedded Assessment for Learning (EAfL) framework in science courses for the gifted affects the students’ views throughout the learning process. The participants were 86 students in three programmes for the gifted who elected project?based science courses. The data included questionnaires, distributed at the beginning and at the end of the assessment processes in each science course, and in?depth interviews with 12 students, which were analysed according to three main themes: general view of assessment; assessment modes; and relationships between assessment and learning. The students viewed the EAfL framework as an integral part of the learning process, and perceived it as a means of expressing autonomous learning and a range of performances; characteristics that correspond with the students’ unique needs. In addition, students addressed cognitive and social processes they had undergone. This implies that assessment which is explicitly designed to promote learning in science courses is a powerful tool for teachers as well as for students, and contributes to meaningful learning.

Abstrak	:	We determine the magnetic field at the focus of a conic section due to a current along the conic section. For a given current ?, it is shown that this magnetic field is the same and equal to  for all conics with the same semilatus rectum ?.

Abstrak	:	We discuss two mechanical systems in which the approximate equations of motion are the same as the rapid adiabatic passage of a two-state quantum-mechanical system, such as that which occurs with quasistatic interactions and from the quasiperiodic action of a chirped-frequency laser pulse. We discuss a pair of masses on springs, weakly coupled by another spring, one of whose spring constants varies slowly, and a pair of coupled pendula, where the length of one pendulum slowly changes. In each example an approximation analogous to the rotating-wave approximation used in the corresponding quantum system brings the second-order macroscopic equations of motion into first-order form, and a slow variation in a system parameter characteristic leads to adiabatic change and rapid adiabatic passage.
