When she is not in discussions with students, she mills around the areas where her students work, moving from group to group, sometimes asking questions, sometimes just listening and observing before she joins the next group. In efforts to try to overcome or at least abate inherent bias that results in inequitable treatment, teachers, and all those working with students, need to be examined and keep a check on the bias that enters into their own questioning, thinking, and responses. These intermediate steps often emerge as the study progresses, often in lesson design and planning but also on the spot in the classroom as information about the students' levels of understanding become clearer, new special interests become apparent, or unexpected learning difficulties arise. These opportunities are part of the natural flow of classroom life, indistinguishable for her and for the students from collecting data, discussing findings, planning next steps, drawing conclusions, and communicating findings about the main concepts they are expected to learn. Do you enjoy reading reports from the Academies online for free? Without an understanding of both student learning and the science involved, upon hearing the proper terms from his students, he may have proceeded with his unit with the impression that the students shared a scientific understanding of force (for a class transcript and analysis by the teacher, see Minstrell, 1992). As the students began to talk in their groups, Ms. R added elements to the activity. In the first vignette, Ms. K is helping her students by painting the broad landscape so that they can see how their work fits into a wider context. The volume discusses how classroom assessment differs from conventional testing and grading-and how it fits into the larger, comprehensive assessment system. Formative assessment refers to assessments that provide information to students and teachers that is used to improve teaching and learning. Each student has an index card on which to write questions or request an opportunity to speak with the teacher rather than to interrupt. The anonymity of students is an advantage in … Student participation becomes a key component of successful assessment strategies at every step. Good records also can serve to address issues of accountability, a topic that will be discussed in the next chapter. P.R. the effectiveness of activities in producing the desired learning outcome, the effectiveness of the selected examples, and, the understanding and abilities students must have to benefit from the selected activities and examples. In addition, Emily's final conclusion (calcium chloride causes the heat) is incorrect because it omits the addition of water or a water-based liquid. Questions concerning these different forms of validity need to be addressed independently, although they are often related. The student is encouraged to take smaller steps toward learning a particular concept or skill. Painting the broad landscape for the entire class will give those who are struggling to find a broader context for their work and sustain their inquiries, so she decides to create an opportunity to do so. In pairs, students can be placed in … Because they are stretched thin with resources and time, teachers need support in helping them realize the potential of this type of assessment. One of her responsibilities is to help the students understand and share the goals, which will become progressively clearer to them as the inquiry progresses. 0000029012 00000 n
Effective questioning that elicits quality responses is not easy. These icons convey the same general meaning of traffic lights and are so labeled in the class. This complexity is important to consider when developing a rich and comprehensive assessment system. 0000003093 00000 n
Assessments can be most powerful when students are involved in the process, not solely as responders or reactors. A focus on assessment cuts across multiple standards areas. H�\�ώ�0��~�9�+e��I8��b��F���mVM������;�fAN[��|��d���"��l�n+���@��J�a�lϞ���� After observations and listening to students discuss instruments, Ms. R made the judgment that her students were ready to continue with the activity. The class had been studying DNA and had spent the class hour constructing a DNA model with colored paper representing different nucleotide bases. trailer
the environment surrounding the test format (e.g., the imposed testing for accountability purposes) or the format itself is more problematic. Rather, she states that calcium chloride needs a liquid to conduct heat. I think that the water and the calcium chloride produced the heat. The teacher is able to see whether students are struggling with an activity or concept, whether they have developed fundamental understandings, whether they need to revisit a particular idea or need more practice to develop particular skills. Like Jonathan, Stephanie uses chemical notation of some of her own abbreviations. Again, teachers can use various ways to help students develop and cultivate these insights. Here again, depth in a teacher's subject-matter knowledge is essential. Such a process not only helps to make the criteria more useful; it increases their ownership of the standards by which judgments will be made about their work. Assessment is the gathering of information in the form of data. The opportunity that Ms. R's students had to design, build, and then rebuild instruments based on their trials gives them a chance to make good use of feedback to improve their piece of work. The Standards convey a view of assessment and learning as two sides of the same coin and essential for all students to achieve a high level of understanding in science. A teacher can facilitate this process by providing opportunities for participation and multiple points of entry, but students actually have to take the necessary action. Mr. Howard has been teaching fifth grade for several years, and this year, he has been switched to a second grade classroom. It is important for teachers to have clear performance criteria in mind before they assess student work and responses. In a whole-class discussion, teachers can create opportunities to listen carefully to student responses as they reflect on their work, an activity, or an opportunity to read aloud. Ms. R sent the students to work in their groups. She also is able to note progress that occurs throughout the project, as well as from the last time she engaged in a similar activity with students. To help design and implement an effective and efficient classroom assessment system, we offer the. For one, assessments should be aligned with curricular goals, and should be consistent with pedagogy. Click here to buy this book in print or download it as a free PDF, if available. If students are expected to effectively participate in the process, they then need to be clear on the target and the criteria for good work, to assess their own efforts in the light of the criteria, and to share responsibility in taking action in the light of feedback. Summative assessments summarize what students have learned at the conclusion of an instructional segment. The C.C. You're looking at OpenBook, NAP.edu's online reading room since 1999. The information will be used to plan the next design activity. When looking at work, it is important to ask critical questions, such as “For what does this provide evidence? 0
The data produced from the variety of assessments illustrated in the vignettes are not only useful for the teachers but also as essential tools in helping students to realize where they stand in relation to their goals. Jump up to the previous page or down to the next one. √ planning experiments that address a particular question, √ keeping clear, detailed records of plans, results, and conclusions. These should be conveyed to students. These are often informal and ongoing, though they need not be. Reliability refers to generalizability across tasks. Describe to the class the purpose (function) that the other parts of the instrument have. All rights reserved. Although there is no one way to develop peer- and self-assessment habits in students, successful methods will involve students in all aspects of the assessment process, not solely the grading after an exercise is completed. She uses this information to make decisions about work time, about support she needs to provide, and about resource suggestions. Ms. R brought in sixth graders to assist her third graders while they made instruments. However, this can only be done in light of the teacher's beliefs about how best to help students to learn. If a teacher notices that one student seems to understand (for example, by displaying a green “traffic light”) while another does not, the one who understands might help the one who does not. She moved among groups, listening and adding comments. <<0DBAA3CF5129EF4DBA2A42F925F7BDD6>]>>
Making assessment an integral part of daily mathematics instruction is a challenge. This fact highlights the importance of the nature and form of the information provided to students. Having posed these questions as a guide, it is important to note that no one blueprint or single best model exists for using assessment as a tool that, first and foremost, supports and facilitates student learning. The journals prepared by Ms. K's students and the individual reflections of Ms. R's provided the teachers with an indication of their understanding of the scientific concepts they were working with, and thereby allowed them to gain new and different insights into their respective students' work. For the data to be useful in guiding instructional decisions, the assessment methods should be consistent with the desired pedagogy. This is important if we hope to support all students. However, she does not control variables in her next experiment, when she combines calcium chloride and water. As noted previously, no one system or collection of strategies will serve all teachers. The extent to which any assessment data inform teaching and influence learning depends in a large part on use. One teacher might carry a clipboard while circulating around the room to record comments and observations. Specific information regarding the sources of confusions can be useful in planning activities or in initiating a conversation between students and the teacher. When the reaction's results are cold, she correctly concludes that this mixture has nothing to do with the production of heat. Rather, he states that water and calcium chloride produce the heat. With large class sizes and competing priorities, some teachers may find it impractical to employ certain practices. Science Content: The K-4 science content standard on science and technology is supported by the idea that students should be able to communicate the purpose of a design. Jonathan uses his own abbreviation for calcium chloride, C.C. Teachers in effective classrooms communicate with students about what they should be learning and track progress often. The following example from the Lawrence Hall of Science assessment handbook (Barber et al., 1995) demonstrates how assessment mechanisms can enrich science investigations and provide the teacher with useful information. (p. 152), These students were able to arrive at some part of what would be a correct conclusion, though the degree to which the students used logical reasoning, or supported their conclusions with data, varied widely.
