People from Jers...Thanks for the great explanation. People from Jersey are great (my mom grew up in Somerville).<br />Down in Maryland, it's a little hard to tell what we will be using. The LEAs are to develop their own, using state guidance, with the test score component having to be atleast 20%. Why 20%? The fellow from the state could not provide me with any research supporting 20% as the optimal determinant for teacher quality.<br />The state's explanation is here (http://msde.state.md.us/tpe/TPEG/Chapter12.pdf) and this is what LEA will use if they can't come to agreement within the individual counties.<br />edlharrishttps://www.blogger.com/profile/14052852615803884665noreply@blogger.comtag:blogger.com,1999:blog-9025948832913694345.post-48651778929346685212013-03-12T14:59:37.670-07:002013-03-12T14:59:37.670-07:00And to take it to the next (il-) logical step, how...And to take it to the next (il-) logical step, how does the breakdown of teacher effectiveness rating work? SGP and observation of classroom practice are apples and orangutans. <br /><br />How do we calculate 20 students' SGP scores as 35% (35% of...what?), classroom observations as 50%, and other testing measures as 15% of...what, a "4", which is a "Highly Effective" rating? What's the math that calculates the SGP scores of 20 students to represent 35% of a "4", and the 1 through 4 rating in each of four Domains as 50% of a "4"? How is that calculated? How DO those scores become 35%, and 35% of what???!!<br /><br />This seems more and more like "what's the difference between a duck," "is it closer to New York or by car," or the sound of one hand clapping.<br /><br />I take great pride in my job and I take it seriously. I understand its importance and the impact it has on my students' lives. I have no argument with being held accountable for that impact. However, this seriously flawed and rushed evaluation model does not--and cannot--measure that impact with any accuracy whatsoever. It has no ability to inform my professional growth and therefore, no chance of improving my students' achievement.<br /><br />It might be a somewhat interesting thought experiment, funny, or sad... if my career, livelihood, and my home didn't depend on it. Since they do, it's terrifying and dangerous.<br /><br />--LisaUnknownhttps://www.blogger.com/profile/15944318060384221497noreply@blogger.com
