Promising automated and semi-automated alignment tools have recently become available. Unfortunately, recent alignment evaluation studies report low inter-rater reliability, e.g., 32% with two raters and 35 documents. While these results are in line with studies in other domains, low reliability makes it difficult to accurately train automatic systems and complicates comparison of different services. We propose that inter-rater reliability of broadly defined, abstract concepts such as 'alignment' or 'relevance' must be expected to be low due to the real-world complexity of teaching and the multidimensional nature of the curricular documents. Hence, we suggest decomposing these concepts into less abstract, more precise measures anchored in the daily practice of teaching. This article reports on the integration of automatic alignment results into the interface of the TeachEngineering collection and on an evaluation methodology intended to produce more consistent document relevance ratings. Our results (based on 14 raters x 6 documents) show high inter-rater reliability (61-95%) on less abstract relevance dimensions while scores on the overall 'relevance' concept are (as expected) lower (64%). Despite a relatively small sample size, regression analysis of our data resulted in an explanatory (R 2 = .75) and statistically stable (pvalues < .05) model for overall relevance as indicated by matching concepts, related background material, adaptability to grade level, and anticipated usefulness of exercises. Our results suggest that more detailed relevance evaluation which includes several dimensions of relevance would produce better data for comparing and training alignment tools.

This curricular concept and accompanying building data system at the ITL laboratory is called`Building-as-a-Learning-Tool,' or BLT. The web-based BLT software system continuously monitors more than 300 building systems sensors, enabling engineering faculty and students to use the BLT system as a distance-learning tool to take the`pulse' of the building from anywhere in the world (see http://blt.colorado.edu).

In fact, the building itself serves as a laboratory instrument with more than 300 sensors embedded throughout the building and the opportunity to perform experiments on the building itself. All the sensor data are available on the Web. The ITLL is truly an example of Winston Churchill's quote-"first we shape our buildings and then our buildings shape us."
