Learning Progressions is a topic that I have not heard much about until reading the articles from this week. I do like the overall idea that students can build on the information that they learn, and develop a more comprehensive understanding. If I understood the articles correctly, I took away that learning progressions are almost like a trajectory the students can follow to arrive at a level of understanding that someone defines as appropriate. The theoretical significance of a “learning progression” is to develop an idea that could lead students to become scientifically literate. In the Journal of Research in Science Teaching, the Editorial by Duncan et al., highlighted many interesting, and what I would even deem controversial, aspects of learning progressions. The first being what role does the teacher and other instructional interventions play in the success of a learning progression? On page 608 Duncan et al. stated, “The question of how intimately linked curriculum and instruction are to progression also remains open. On one hand, we noted in our definition that LPs are not developmentally inevitable and depend on targeted instruction; on the other hand, LPs are essentially theoretical constructs that are not intended to be tied to a specific instructional intervention. The articles in this issue differ in regard to the emphasis they place on instruction and whether or not instructional interventions are necessary for the empirical validation of the progression.” I wonder myself how greatly learning progressions depend on the work (ex. scaffolding and other instructional measures) teachers perform to get their students to understand the material. It also makes me wonder how else would the learner get to the next level?
On page 606-607 Duncan et al. also stated, “Second, these progressions are bounded by an upper anchor describing what students are expected to know and be able to do by the end of the progression; this anchor is informed by analyses of the domain as well as societal expectations.” This being said, if the society standards are a major factor to the success of a learning progression, at what level in society would this be defined? Would it be by what the teacher deemed the society standard, or would it be at a higher level–state or national?
I found the Steedle and Shavelson article titled Supporting Valid Interpretations of Learning Progression Level Diagnosis useful to have a better understanding of the complications with learning progressions. Although learning progressions are theoretically a great idea, the assessment potentially used to validate the success of learning progression is tricky to perform. Steedle and Shavelson pointed out that particular points of a learning progression do not always allow for a specific analysis. After reading this article I felt a bit skeptic about learning progressions as a tool to be used in the classroom. If specific analysis is too difficult to do with the learning progression, would this tool be somewhat unfair to be practiced in classrooms or even implemented on a standard basis?
The question previously asked was further justified by what I read in the Mark Wilson article. As Wilson noted on page 716 in the article titled Measuring Progressions: Assessment Structures Underlying a Learning Progression, “Devising means of measuring a student’s location within or along a learning progression is a crucial step in advancing the scientific study of learning progressions, and for finding educationally useful applications of the idea.” The idea of a construct map, which would be a tool used to help researchers understand how assessment tools can be related to cognition. I found Wilson to be easy to read, and I thought the metaphor provided to understand the relationship between learning progressions and assessment thoughtful and helpful. On page 717 Wilson stated, “In order to illustrate certain aspects of the relationship between learning progressions and assessment, I will use a visual metaphor that superimposes images of construct maps on an image of a learning progression. This image of the learning progression is shown in Figure 1, where the successive layers of the ”thought clouds” are intended to represent the successive layers of sophistication of the student’s thinking, and the increase in the cloud’s size is intended to indicate that the thoughts become more sophisticated later in the sequence (e.g., they have wider applicability later in the sequence). The person in the picture is a someone (a science educator, a science education researcher, an assessment developer?) who is thinking about student thinking. In other circumstances (e.g., Wilson, 2005), I have called this person the ”measurer,” though not here, as the ideas being examined in the article are mainly at an early point in the development of assessments, focusing on the first of the building blocks. It is important to recall that this learning progression is in the researcher’s thoughts, and that it represents a hypothesis about the students’ thoughts that will be examined empirically, eventually.” Overall, I thought Wilson provided a good building block for a tool that could be potentially used to give more grounding to an assessment.
Finally, the Songer et al. article titled How and When Does Complex Reasoning Occur? Empiracally Driven Development of a Learning Progression Focused on Complex Reasoning about Biodiversity was an article that showed the application of a three year learning progression. I thought the overall goal of these researchers was attention-grabbing, because they were motivated by the fact that an American students are not on a competitive scientific level of understanding that international science learners are at. I thought that Songer et al. made a good point that the definition of learning progressions is oversimplified. A learning progression is not strictly content knowledge, but there is a level of inquiry that is developing as well that must be included throughout the progression. Songer et al. also raised a good point about the evaluation of a successful learning progression. On page 611 they argued that neither the content or inquiry portion of a learning progression could be evaluated directly, but rather they are just resources that could be empirically evaluated.
Overall, I excited to be able to discuss these articles in class next week. I guess after completing these readings I am still at a loss for how the assessment and evaluation of learning progressions can take place (which seems to be the question that everyone is asking)?
