This paper examines teacher cognitions about interpersonal behavior in the classroom in
relation to the teacher behavior perceived by students. The cognitions studied are the teachers…

The authors describe the development and evaluation of a teacher induction programme
designed to help beginning teachers to bridge the gap between teaching as a student‐teacher …

An alternating current photoelectric device has been used for determining the yield factor p
of resonance flourescence of the yellow sodium doublet and the infrared and blue potassium …

Over the past twenty five years a number of trends in physics education at the secondary level
have developed. These include (1) more emphasis on technological and social aspects of …

Results are presented of an extended case study of a teacher who was confronted with severe
discipline problems. This teacher changed the aggressive disorder in her lessons into a …

The influence of radiative non-equilibrium on the occupation of excited metal states in
flames can be investigated by measuring the deviation ΔT of line reversal (or excitation) …

An ac photoelectric detection device has been used to determine the yield factor p of
resonance fluorescence of the Na(5890/96) Å and K(7665/99) Å and (4044/47) Å resonance …

An alternating current photoelectric device (compare the work of Boers et al., (1) Alkemade, (2)
Hooymayers et al. (3,4) and Hooymayers (5) ) has been used for determining the yield …

An explicit expression for the intensity of atomic resonance fluorescence as a function of atomic
concentration in a flame is derived under certain idealized conditions. The expression is …

Experimental noise spectra in the frequency range of 15–10 5 Hz are reported for the thermal
emission of the first resonance doublet of Na and K in a premixed H 2 -O 2 -N 2 flame, and …
