СКАЧАТЬ many of the basic assumptions underlying good formative assessment. As James McMillan (2007) explained:

      These tests, which are typically provided by the district or commercial test publishers, are administered on a regular basis to compare student achievement to “benchmarks” that indicate where student performance should be in relation to what is needed to do well on end-of-year high stakes tests…. Although the term benchmark is often used interchangeably with formative in the commercial testing market, there are important differences. Benchmark assessments are formal, structured tests that typically do not provide the level of detail needed for appropriate instructional correctives. (pp. 2–3)

      The second thing to keep in mind is that while there is a good deal of agreement about its potential as a tool to enhance student achievement, the specifics of formative assessment are somewhat elusive. In fact, most descriptions of formative assessment are very general in nature. To illustrate, in their original study, Black and Wiliam (1998a) noted that “formative assessment does not have a tightly defined and widely accepted meaning” (p. 7). Dylan Wiliam and Siobhan Leahy (2007) described formative assessment as follows:

      The qualifier formative will refer not to an assessment or even to the purpose of an assessment, but rather to the function it actually serves. An assessment is formative to the extent that information from the assessment is fed back within the system and actually used to improve the performance of the system in some way (i.e., that the assessment forms the direction of improvement). (p. 31)

      Rick Stiggins, Judith Arter, Jan Chappuis, and Stephen Chappuis (2006) described formative assessment as assessment for learning rather than assessment of learning:

      Assessments for learning happen while learning is still underway. These are the assessments that we conduct throughout teaching and learning to diagnose student needs, plan our next steps in instruction, provide students with feedback they can use to improve the quality of their work, and help students see and feel in control of their journey to success…. This is not about accountability—these are assessments of learning. This is about getting better. (p. 31)

      Susan Brookhart and Anthony Nitko (2007) explained that “formative assessment is a loop: Students and teachers focus on a learning target, evaluate current student work against the target, act to move the work closer to the target, and repeat” (p. 116).

      Along with these general descriptions, specifics regarding the practice of formative assessment have been offered. Unfortunately, there is no clear pattern of agreement regarding the specifics. For example, some advocates stress that formative assessments should not be recorded, whereas others believe they should. Some assert that formative assessments should not be considered when designing grades, where others see a place for them in determining a student’s true final status (see O’Connor, 2002; Welsh & D’Agostino, 2009; Marzano, 2006). To a great extent, the purpose of this book is to articulate a well-crafted set of specifics regarding the practice of formative assessment.

       Learning Progressions and Clear Goals

      The development of learning progressions has become a prominent focus in the field of formative assessment. Margaret Heritage (2008) explained the link between learning progressions and formative assessment as follows:

      The purpose of formative assessment is to provide feedback to teachers and students during the course of learning about the gap between students’ current and desired performance so that action can be taken to close the gap. To do this effectively, teachers need to have in mind a continuum of how learning develops in any particular knowledge domain so that they are able to locate students’ current learning status and decide on pedagogical action to move students’ learning forward. Learning progressions that clearly articulate a progression of learning in a domain can provide the big picture of what is to be learned, support instructional planning, and act as a touchstone for formative assessment. (p. 2)

      One might think that learning progressions have already been articulated within the many state and national standards documents. This is not the case. Again, Heritage noted:

      Yet despite a plethora of standards and curricula, many teachers are unclear about how learning progresses in specific domains. This is an undesirable situation for teaching and learning, and one that particularly affects teachers’ ability to engage in formative assessment. (p. 2)

      The reason state and national standards are not good proxies for learning progressions is that they were not designed with learning progressions in mind. To illustrate, consider the following standard for grade 3 mathematics from the state of Washington (Washington Office of Superintendent of Public Instruction, 2008):

      Students will be able to round whole numbers through 10,000 to the nearest ten, hundred, and thousand. (p. 33)

      This sample provides a fairly clear target of what students should know by grade 3, but it does not provide any guidance regarding the building blocks necessary to attain that goal. In contrast, Joan Herman and Kilchan Choi (2008, p. 7) provided a detailed picture of the nature of a learning progression relative to the concept of buoyancy. They identified the following levels (from highest to lowest) of understanding regarding the concept:

      • Student knows that floating depends on having less density than the medium.

      • Student knows that floating depends on having a small density.

      • Student knows that floating depends on having a small mass and a large volume.

      • Student knows that floating depends on having a small mass, or that floating depends on having a large volume.

      • Student thinks that floating depends on having a small size, heft, or amount, or that it depends on being made out of a particular material.

      • Student thinks that floating depends on being flat, hollow, filled with air, or having holes.

      Obviously, with a well-articulated sequence of knowledge and skills like this, it is much easier to provide students with feedback as to their current status regarding a specific learning goal and what they must do to progress.

      While one might characterize the work on learning progressions as relatively new and therefore relatively untested, it is related to a well-established and heavily researched area of curriculum design—learning goals. One might think of learning progressions as a series of related learning goals that culminate in the attainment of a more complex learning goal. Learning progressions can also be used to track student progress. The research on learning goals is quite extensive. Some of the more prominent studies are reported in table 1.5 (page 12).
