these mixed choice item normats(properly) incrudes an iteration that is in the free-response format(this point is returned to in Sec- tion 3.3) The outcome space for the LBC matter constructs is summarized in Fig. 1.5-it is divided into ordered categories because the LBC curriculum developers see the underlying latent construct as a di mension-that is, as they see the students as progressing from little of it at the beginning of the year, and(ifthe curriculum developers and teachers have been successful) to having more at the end. This scoring guide allows a teacher to score student responses to the questions related to the matter constructs into the six different lev- els. Level 1, "Describing," has been further differentiated into three ordered sublevels- similar differentiation is planned for the other levels where it is found to be appropriate. Note how the scores(even the and relate the categories to the desired direction of student progress. As well as the scoring guide in Fig. 1.5, teachers have available to them examples of student work(called exemplars in LBC), complete with adjudicated scores and explanations of the scores. An example is shown in Fig. 1.6. A training method called moderation is also used to help teachers be accurate raters and in- terpret the results in the classroom(see Wilson& Sloane, 2000, for a discussion of this). Really, it is the sum of all these elements that is the true outcome space, Fig. 1.5 is just a summary of one part of it What we get out of the outcome space is a score, and for a set of tasks it gives a set of scores.
