<description><![CDATA[<P class=MsoNormal style="MARGIN: 0cm 0cm 0pt; TEXT-INDENT: 24pt; LINE-HEIGHT: 25pt; mso-char-indent-count: 2.0; mso-line-height-rule: exactly"><SPAN style="FONT-SIZE: 12pt; FONT-FAMILY: 宋体; mso-ascii-font-family: 'Times New Roman'; mso-hansi-font-family: 'Times New Roman'">今天拿到了上个学期教学考核奖的名细单子，所以在中午吃饭时，在餐桌上无意间谈起了有关教学质量考核的话题。</SPAN><SPAN lang=EN-US style="FONT-SIZE: 12pt"><?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" /><o:p></o:p></SPAN></P>
<P class=MsoNormal style="MARGIN: 0cm 0cm 0pt; TEXT-INDENT: 24pt; LINE-HEIGHT: 25pt; mso-char-indent-count: 2.0; mso-line-height-rule: exactly"><SPAN style="FONT-SIZE: 12pt; FONT-FAMILY: 宋体; mso-ascii-font-family: 'Times New Roman'; mso-hansi-font-family: 'Times New Roman'">今年开始实施绩效工资，可分配的奖金会比原来有所提高。并且校长在开学会议上也说了，要拉开教师间的贫富差距。</SPAN><SPAN lang=EN-US style="FONT-SIZE: 12pt"><o:p></o:p></SPAN></P>
<P class=MsoNormal style="MARGIN: 0cm 0cm 0pt; TEXT-INDENT: 24pt; LINE-HEIGHT: 25pt; mso-char-indent-count: 2.0; mso-line-height-rule: exactly"><SPAN style="FONT-SIZE: 12pt; FONT-FAMILY: 宋体; mso-ascii-font-family: 'Times New Roman'; mso-hansi-font-family: 'Times New Roman'">说到奖金的分配，教师马上会想到学校的教学质量考核方案。领导的出发点是好的，想用拉开奖金的差距来激发教师的工作积极性。但我们教师再讨论的时候最关注的是：考核方案的公平性。</SPAN><SPAN lang=EN-US style="FONT-SIZE: 12pt"><o:p></o:p></SPAN></P>
<P class=MsoNormal style="MARGIN: 0cm 0cm 0pt; TEXT-INDENT: 24pt; LINE-HEIGHT: 25pt; mso-char-indent-count: 2.0; mso-line-height-rule: exactly"><SPAN style="FONT-SIZE: 12pt; FONT-FAMILY: 宋体; mso-ascii-font-family: 'Times New Roman'; mso-hansi-font-family: 'Times New Roman'">可以说许多考核方案只注重静态的结果，考得好就能多拿奖金还能在大会上表扬。好比是在一场比赛中，不管怎样，领导就在终点处守着：谁是第一名？谁是第二名？谁是第三名？你了解教师所教班级的起点吗？这样能提高教师的积极性吗？其实这就涉及到公平性的问题。只要公平，教师的积极性就会提高。</SPAN><SPAN lang=EN-US style="FONT-SIZE: 12pt"><o:p></o:p></SPAN></P>
<P class=MsoNormal style="MARGIN: 0cm 0cm 0pt; TEXT-INDENT: 24pt; LINE-HEIGHT: 25pt; mso-char-indent-count: 2.0; mso-line-height-rule: exactly"><SPAN style="FONT-SIZE: 12pt; FONT-FAMILY: 宋体; mso-ascii-font-family: 'Times New Roman'; mso-hansi-font-family: 'Times New Roman'">说到公平性，我有一点想法：拿提高率来说，假如我接到一个班级，任教一个学期之后有了很大的提高，对于第一学期的考核来说没什么。但对第二学期来说压力会很大，有时会出现这样的情况，平均分，及格率等其他指标还是很突出的，但提高率由于班级上学期考得太好，有点极限的味道，所以这个学期提高率指标很有可能是负的，这一点对于整个教师教学质量考核影响是很大。我想说的是，提高率真的是教师平时一点一滴努力得来的，第二学期就算是负提高能说明教师教书教得不努力了吗？对于提高率有觉得，可能每个学期都参照接班时的基础来考核比较公平。</SPAN><SPAN lang=EN-US style="FONT-SIZE: 12pt"><o:p></o:p></SPAN></P>
<P class=MsoNormal style="MARGIN: 0cm 0cm 0pt; TEXT-INDENT: 24pt; LINE-HEIGHT: 25pt; mso-line-height-rule: exactly"><SPAN style="FONT-SIZE: 12pt; FONT-FAMILY: 宋体; mso-ascii-font-family: 'Times New Roman'; mso-hansi-font-family: 'Times New Roman'">差距得拉开，体现多劳多得，优劳优得，这我很赞成。</SPAN><SPAN lang=EN-US style="FONT-SIZE: 12pt"><o:p></o:p></SPAN></P><SPAN style="FONT-SIZE: 12pt; FONT-FAMILY: 宋体; mso-ascii-font-family: 'Times New Roman'; mso-hansi-font-family: 'Times New Roman'; mso-font-kerning: 1.0pt; mso-bidi-font-family: 'Times New Roman'; mso-ansi-language: EN-US; mso-fareast-language: ZH-CN; mso-bidi-language: AR-SA">&nbsp;&nbsp;&nbsp; 我觉得制定教学质量考核方案时更多地要公平，不要只注重结果。</SPAN>]]></description>
