From mainstream school to pupil referral unit: a change in teachers’ self-understanding

As teachers are at the heart of education, a substantial number of studies have researched the perception that mainstream school teachers have of themselves in relation to their work. This investigation extends this field of inquiry by examining how teachers’ self-understanding is altered when they transfer from mainstream to special school education. This study adopts the methodology of interpretive phenomenological analysis (IPA) to examine in detail how three female teachers in inner London experienced the transition from mainstream secondary schools to teaching in alternative provision for excluded students referred to as a pupil referral unit (PRU). Central to IPA is how an individual experiences a substantial change in life and the influence this may have on his or her world views. The research approach adopted is, therefore, idiographic and reliant on the experiences of a small number of participants. The findings from this investigation indicate that the participants chose to leave mainstream school education when they came to the self-realisation that they wanted to engage in more creative and personally engaging professional practice with a stronger moral purpose. When they started to teach at a PRU, the more persistent and personal relationships with their students brought about a substantial change in self-understanding.

泰勒中值定理在一类极限计算中的应用

运用洛必塔法则和等价无穷小替换是计算未定式0/0值的两种常用方法,但在实际问题的处理中,常常遇到不能直接使用洛必塔法则和等价无穷小需要选择的情形。可运用泰勒中值定理,找到最佳替换的等价无穷小,从而弥补了上述两种常用方法的不足,并从理论上给与了解释。
