Developing this competence should be a main aspect of early childhood teachers’ education. This is, however, not the case in all countries. Consequently, high-quality professional development courses are needed. Based on research results, we developed a competence-oriented continuous professional development course (\"EmMa\") and examined the effects of \"EmMa\" by asking: How does \"EmMa\" affect the development of early childhood teachers’ i) mathematical content knowledge, ii) mathematical pedagogical content knowledge and iii) beliefs towards mathematics in general? To answer these questions, we conducted a pre-test/post-test study including a control group with 99 in-service early childhood teachers. Results show that the course affected teachers’ mathematical pedagogical content knowledge and static orientation towards mathematics positively. From this we conclude that scaling-up \"EmMa\" might be a suitable approach to bridge the gap between pre-service education with nearly no mathematics and the challenges of early mathematics education.","lang":"eng"}],"page":"76–93","citation":{"short":"J.

It is shown how theses statistics can be obtained from the training sequences present in downlink transmission bursts without establishing an active connection. Realistic simulations of a GSM channel according to the COST 207 channel models have been conducted. These models incorporate effects like multipath propagation, fading, cochannel interference and additive noise. It is shown that velocity estimation by searching for the maximum slope of the power density spectrum of the fast fading performs best."}]},{"issue":"3","_id":"11778","intvolume":" 9","year":"2001","type":"journal_article","citation":{"ieee":"R.
