The Effectiveness and Efficiency of Distributed Online, Regional Online, and Regional Face-to-Face Training for Writing Assessment Raters
Edward W. Wolfe, Staci Matthews, and Daisy Vickers
This study examined the influence of rater training and scoring context on training time, scoring time, qualifying rate, quality of ratings, and rater perceptions. 120 raters participated in the study and experienced one of three training contexts: (a) online training in a distributed scoring context, (b) online training in a regional scoring context, and (c) stand-up training in a regional context. After training, raters assigned scores to qualification sets, scored 400 student essays, and responded to a questionnaire that measured their perceptions of the effectiveness of, and satisfaction with, the training and scoring process, materials, and staff. The results suggest that the only clear difference on the outcomes for these three groups of raters concerned training time—online training was considerably faster. There were no clear differences between groups concerning qualification rate, rating quality, or rater perceptions.

Impressions of 2010 CCSSO Conference
This year, the Council of Chief State School Officers (CCSSO) Large-Scale Assessment conference took place in Detroit, the world's automotive center. The weather was a pleasant contrast compared to the heat in Texas, where I live and work. As the conference overlapped with River Days, it was nice to share in the festive atmosphere. The 30-minute fireworks display was splendid.
The participants in the CCSSO conference were quite different from those in NCME or in AERA Division D. The psychometrician/research scientist was a “rare animal.” However, the conference provided a good opportunity to meet assessment users from different states’ Departments of Education.
Most of the presentations were neither technical nor psychometric in orientation but they provided information about the trend of large-scale assessment in the United States. This year, the topics, like Race to the Top, Common Core Standards, and Best Assessments Practice, were especially “hot.”
Not many people showed up for my presentation. It might be the title, “…Threats to Test Validity….” Was it too technical?
Pearson proudly sponsored a reception buffet dinner with live music and several vice presidents greeted guests at the door. The dinner provided an enjoyable situation in which to meet and build relationships with others in the assessment field. I met a number of colleagues from global Pearson and I felt proud to be a member of this big family.

Abandoning the Pejorative
Psychometricians often speak of error in educational and psychological measurement. But error seems like such a pejorative term. According to the Merriam-Webster online dictionary Merriam-Webster Dictionary, an error is "an act involving an unintentional deviation from truth or accuracy." In ordinary language, error suggests unflattering connotations and alarming inferences.
Under classical test theory, error is the difference between observed student performance and an underlying "true score." But who has special insight into what is true? As Nichols, Twing, Mueller and O’Malley in their recent standard setting article* point out, human judgment is involved in every step of test development. Typically, a construct or content framework describing what we are trying to test is constructed by experts. But the experts routinely disagree amongst themselves and certainly disagree with outside experts. The same expert may even later disagree with a description constructed by them earlier in their career! So what psychometricians call error is just the difference between how one group of experts expects students to perform and how students actually perform.
Psychometricians might even be able to control the amount of "error" by careful selection of what they declare is true. After all, the size of the difference between the experts' description and student performance, or error, depends on what experts you listen to or when you catch them. A strategy for decreasing error might be to gather a set of experts' descriptions and declare as “true” the experts' description that shows the smallest difference between how experts' expect students to perform and how students actually perform. Who is to say this group of experts is right and that group of experts is wrong?
So let's agree to abandon the pejorative label "error" variance. The variance between how one group of experts expects students to perform and how students actually perform might be more appropriately referred to as "unexpected" or "irrelevant." Let's recognize that this variance is irrelevant to the description constructed by the experts, i.e., construct irrelevant variance. Certainly this unexpected variance threatens the interpretation of student performance using the experts' description. But does the unexpected deserve the pejorative label "error?"

Innovative Testing
Innovative testing refers to the use of novel methods to test students in richer ways than can be accomplished using traditional testing approaches. This generally means the use of technology like computers to deliver test questions that require students to watch or listen to multimedia stimuli, manipulate virtual objects in interactive situations, and/or construct rather than select their responses. The goal of innovative testing is to measure students’ knowledge and skills at deeper levels and measure constructs not easily assessed, such as problem solving, critical analysis, and collaboration. This will help us better understand what students have and haven’t learned, and what misconceptions they might hold—and thus support decisions such as those related to accountability as well as what instructional interventions might be appropriate for individual students.
Educational testing has always involved innovative approaches. As hidden properties of students, knowledge and skill are generally impossible to measure directly and very difficult to measure indirectly, often requiring the use of complex validity arguments. However, to the extent that newer technologies may allow us to more directly assess students’ knowledge and skills—by asking students to accomplish tasks that more faithfully represent the underlying constructs they’re designed to measure—innovative testing holds the promise of more authentic methods of testing based upon simpler validity arguments. And as such, measurement of constructs that are “higher up” on taxonomies of depth of understanding, such as Bloom’s and Webb’s, should be become more attainable.
Consider assessing a high school student’s ability to design an experimental study. Is this the same as his or her ability to identify one written description of a well-designed experiment amongst three written descriptions of poorly designed experiments? Certainly there will be a correlation between the two; the question is how good a correlation, or more bluntly, how artificial the context. And further, to what extent is such a correlation a self-fulfilled prophesy, such that students who might be good at thinking and doing science but not at narrowly defined assessment tasks are likely to do poorly in school as a result of poor test scores due to the compounding impact of negative feedback?
Many will recall the promise of performance assessment in the 90’s to test students more authentically. Performance testing didn’t live up to its potential, in large part because of the challenges of standardized administration and accurate scoring. Enter innovative questions—performance testing riding the back of digital technologies and new media. Richer assessment scenarios and opportunities for response can be administered equitably and at scale. Comprehensive student interaction data can be collected and scored by humans in efficient, distributed setting, automatically by computer, or both. In short, the opportunity for both large-scale and small-scale testing of students using tasks that more closely resemble real-world application of learning standards is now available.
Without question, creating innovative test questions presents additional challenges over that of simpler, traditional ones. As with any performance task, validity arguments become more complex and reliability of scoring becomes a larger concern. Fortunately, there has been some excellent initial work in the area of understanding how, including the development of taxonomies and rich descriptions for understanding innovative questions (e.g., Scalise; Zenisky). Most notable are two approaches that directly address validity. The first is evidence-centered design, an approach to creating educational assessments in terms of evidentiary arguments built upon intended constructs. The second is a preliminary set of guidelines for the appropriate use of technology in developing innovative questions through application of universal design principles that take into account how students interact with those questions as a function of their perceptual, linguistic, cognitive, motoric, executive, and affective skills and challenges. Approaches such as these are especially essential if we are to help ensure the needs of students with disabilities and English language learners are considered from the beginning in designing our tests.
Do we know that innovative questions will indeed allow us to test students to greater depths of knowledge and skill than traditional ones, and whether will they do so in a valid, reliable, and fair manner? And will the purported cost effectiveness be realized? These are all questions that need ongoing research.
As we solve the challenges of implementing innovative questions in technically sound ways, perhaps the most exciting aspect of innovative testing is the opportunity of integration with evolving innovative instructional approaches. Is this putting the cart before the horse to focus so much on innovation in assessment before we figure it out in instruction? I believe not. Improvements to instructional and assessment technologies must co-evolve. Our tests must be designed to pick up the types of learning gains our students will be making, especially when we consider 21st century skills, which will increasingly rely on innovative, technology-based learning tools. Plus our tests have a direct opportunity to impact instruction: despite all our efforts, “teaching to the test” will occur, so why not have those tests become models of good learning? And even if an emphasis on assessment is the cart, at least the whole jalopy is going the correct way down the road. Speaking of roads, consider the co-evolution of automobiles and the development of improved paving technologies: improvement in each couldn’t progress without improvement in the other.
