... National Science Teaching Association 1840 Wilson Boulevard, Arlington VA 22201 (T) 703.243.7100 (F) 703.243.7177 Los Angeles, CA: National Center for Research on Evaluation, Standards, and Student Testing. DATA: Students' written responses. Formative and summative assessments are both important and useful, but require different approaches and interpretations. Equally important, it serves as a capstone experience for the school science program. Assessment practices and policies provide operational definitions of what is important. You're looking at OpenBook,'s online reading room since 1999. Assessment in Science Education: The Middle Years. This choice of assessment would be based on the following assumed relationship: the management system gives teachers responsibility for selecting the science programs, teachers have an incentive to implement effectively the programs they select, and effective implementation improves science achievement. The book is on the desk, the desk is on the floor, the floor is a part of the building, the building is sitting on the Earth, the Earth is rotating on its axis and revolving around the Sun, and the whole solar system is moving through the Milky Way." Can there be validity without reliability? The jar is located in a window where it receives sunlight. People who must use the results of assessments to make decisions and take actions, as well as those who are affected by the decisions and actions, deserve assurance that assessments are carefully conceptualized. Specifications of the number of students or schools from which data will be obtained. Champagne, E. Haertel, I.V. To illustrate the assessment standards, two examples are provided below. ASSESSMENT PURPOSE: The teacher uses the information from this activity to improve the lesson. Authentic assessment exercises require students to apply scientific knowledge and reasoning to situations similar to those they will encounter in the world outside the classroom, as well as to situations that approximate how scientists do their work. Students have adequate opportunity to demonstrate their achievements. Often referred to as summative assessment or assessment of learning, this is evaluation that occurs at the end of a period of instruction and often results in a grade that summarizes what a learner knows. Assessment tasks must be developmentally appropriate, must be set in contexts that are familiar to the students, must not require reading skills or vocabulary that are inappropriate to the students' grade level, and must be as free from bias as possible. Assessment and learning are so closely related that if all the outcomes are not assessed, teachers and students likely will redefine their expectations for learning science only to the outcomes that are assessed. In contrast, the bird watching from the edge of the stream would describe the motion of the lily pad and its passengers in terms of its reference frame, namely the ground on which it was standing. Teachers are in the best position to put assessment data to powerful use. Opportunity-to-learn data collected focus on the most powerful indicators. Finally, student performances with respect to the rubric are differentiated. Some data teachers have collected themselves; other data come from external sources. Data-collection methods can take many forms. Clearly relating assessment tasks and products of student work to the valued goals of science education is integral to assessment plans. After setting the class to work discussing the questions, the teacher walks around the room listening to the discussions. Some indicators of opportunity to learn have their origins at the federal, state, and district levels and are discussed in greater detail in the systems standards. This gives the teacher an idea of where the learners are in their learning and where they need to go. For example, in the district management example above, the relationship between the management system and student achievement is not adequately tested if student achievement is the only variable measured. However, even the citizen's understanding will have different perspectives, reflecting differences in experience and exposure to science. development of the technical skills to assess opportunity to learn among science education professionals, including teachers, supervisors, administrators, and curriculum developers. Judgments about the appropriateness of the information are more difficult to make. The teacher encourages but does not require students to work together in research groups of two to four students. For an assessment to be internally consistent, each component must be consistent with all others. 1991. Elementary School Science for the '90s. Once the teacher collects this evidence he or she interprets and record  all the information. These types of questions are also known as indirect or open questions. An essential responsibility of teachers is to report on student progress and achievement, to the students themselves, to their colleagues, to parents and to policy makers. The example illustrates how thoughtfully designed assessment exercises requiring explanations provide students with the opportunity to demonstrate the full range of their scientific understanding. For all large-scale assessments, even those at the district level, the information should be collected in ways that minimize the time demands on individual students. The statements form a connected progression. The chapter closes with. ASSESSMENTS HAVE EXPLICITLY STATED PURPOSES. It can be based on experience or theory, and it uses ideas from the physical, life, and earth sciences, as well as cross-disciplinary ideas, thus allowing students to demonstrate the full range of. When students are engaged in assessment tasks that are similar in form to tasks in which they will engage in their lives outside the classroom or are similar to the activities of scientists, great confidence can be attached to the data collected. Whether at the district, state, or national level, teachers of science need to work with others who make contributions to the assessment process, such as educational researchers, educational measurement specialists, curriculum specialists, and educational policy analysts. Assessment needs to occur on a continuing basis during the year and will involve: Assessment for Learning – the process of seeking and interpreting evidence for use by learners and their teachers to decide where the learners are in their learning, where they need to go and how best to get there (Assessment Reform Group 2002). Setting a performance standard for a population of students depends on the population's developmental level and their experiences with science. While the class is engaged in the extended investigation, the teacher observes each student's performance as the student makes presentations to the class, interacts with peers, and uses computers and laboratory apparatus. Overcoming this lack of trust requires that teachers use assessment plans for monitoring student progress and for grading. This public confidence is influenced by the extent to which technical quality has been considered by educators and policy makers and the skill with which they communicate with the public about it. Requiring students to pose questions and design inquiries to address them would be an appropriate task. These questions are recorded in student research notebooks. Even when assessments are well planned and the quality of the resulting data high, the interpretations of the empirical evidence can result in quite different conclusions. It uses the carbohydrates and oxygen to produce energy for life processes like growth and motion. The quality of the decisions and the appropriateness of resulting action are limited by the quality of the data. In the work of classroom learning and investigation, teachers represent the standards of practice of the scientific community. NRC (National Research Council). 1. If the principles in the assessment standards are followed, the information resulting from new modes of assessment applied locally can have common meaning and value in terms of the national standards, despite the use of different assessment procedures and instruments in different locales. Understanding and doing inquiry are contingent on knowing concepts, principles, laws, and theories of the physical, life, and earth sciences. Glaser, R. 1992. The system, program, teaching, and professional development standards portray the conditions that must exist throughout the science education system if all students are to have the opportunity to learn science. Still other concepts are from the earth sciences, such as soil types, composition of the atmosphere, water cycle, solar energy, and mineral cycle. Planning for assessment is integral to instruction. This chapter begins with an introduction that describes the components of the assessment process and a contemporary view of measurement theory and practice. A student's progress in mastering the science curriculum. For example, assessment data provide students with feedback on how well they are meeting the expectations of their teachers and parents, teachers with feedback on how well their students are learning, districts with feedback on the effectiveness of their teachers and programs, and policy makers with feedback on how well policies are working. The inferences made from assessments about student achievement and opportunity to learn must be sound. Student E's response is well structured and consistent with the prediction. Effectively questioning using convergent as well as divergent questions 3. For example, assessments that emphasize the acquisition of factual knowledge imply that facts are The ability to use science to make personal decisions and to take positions on societal issues. SNAP explores how performance assessments can be used to support teaching and learning of the NGSS. SEA Usage of Alternative Assessment: The Connecticut Experience. The plant can live because it gets energy from the sunlight. Ideally, the 12th grader would see the plant in a jar as a physical model of the Earth's ecosystem, and view photosynthesis and respiration as complementary processes. Equally important is that the plans have explicit criteria for judging the quality of students' work that policy makers and parents can understand. Can the same expectations be applied across our diverse society? Progress reports provide information about. to the class. A huge amount of research has been done on this area since the Roediger and Karpicke paper, much of it using educationally relevant materials. Critique the work of other students in constructive ways. The example that follows illustrates these challenges. Assessment and Evaluation in Science 1. 1990. DEVELOPING SCORING RUBRICS. Its temperature is maintained between 60° and 80°F. A second student interrupts, "Oh, yes it is. The leaves were yellow. 1992. THE PERFORMANCE OF A SCIENTIFICALLY LITERATE ADULT. Confidence is gauged by the quality of the assessment process and the consistency of the measurement over alternative assessment processes. They also seek responses from other adults. You should know that there is not a single correct prediction. Kuerbis, R.C. Journal of Educational Measurement, 30 (1): 41-53. The interplay of evidence and consequences in the validation of performance assessments. EQUAL ATTENTION MUST BE GIVEN TO THE ASSESSMENT OF OPPORTUNITY TO LEARN AND TO THE ASSESSMENT OF STUDENT ACHIEVEMENT. The situation can be understood by students of all ages, minimizing students' prior knowledge of the situation as a factor in ability to respond. ASSESSMENT AS LEARNING Assessment as learning occurs when students are their own assessors. To learn if the student knows about respiration, one simply has to ask. After a seminar at which the research group presents its data, the analysis, and conclusions, the group prepares a first draft of the research report. The example focuses on predictions and justifying those predictions. The research group Assessment, Teaching and Learning in Science Education studies teaching and learning processes in science education at all educational levels – with a focus on secondary and tertiary education. Assessment tasks must be reviewed for the use of stereotypes, for assumptions that reflect the perspectives or experiences of a particular group, for language that might be offensive to a particular group, and for other features that might distract students from the intended task. I'm pretty sure a plant can live for a long time sealed up in a jar, but I'm not sure how long or exactly what would make it die. Ruiz-Primo, M.A., G.P. Sorry, your blog cannot share posts by email. Well-planned, large-scale assessments include teachers during planning and implementation. The reasoning would be rated higher had the student communicated that. What I'm not sure about is if the gases get used up. The standard response developed by the team of teachers will include concepts from the physical, life, and earth sciences, as well as unifying concepts in science. Write a justification supporting your prediction. their understanding of science at various levels of their study of science. The assessment task begins with a prompt that includes a description of the task and directions. This question checks that students’ ability to recall facts – being able to choose from surface area, concentration of solutions, temperature, pressure, and catalyst, Here the question not only ask students to recall the factors, but asks students to consider the relationship between the chosen factor and rate of reaction, Here the student’s ability to recall other factors are examined. Assessment as Learning. However, if the purpose of. Champagne, E. Haertel, I.V. Especially challenging for teachers is communicating to parents and policy makers the new methods of gathering information that are gaining acceptance in schools. All rights reserved. Assessment design can be … demonstrates reasoning characterized by a succession of statements that follow one another logically without gaps from statement to statement. Each of these issues requires a different kind of information and a different mode of assessment. As plans for investigations evolve, the research questions are sharpened and modified to meet the practical constraints of time and resources available. During this phase of the extended investigation, students engage in an iterative process involving assembling and testing apparatus; designing and testing forms of data collection; developing and testing a data collection schedule; and collecting, organizing, and interpreting data. Loucks-Horsley, S., R. Kapitan, M.O. For example, if the purpose is to decide if a school district's management system should be continued, assessment data might be collected about student achievement. The second assessment example focuses on inquiry. Rather the steps in developing a rubric are described. Furthermore, the justification does not proceed in a sequential way, proceeding from general principles or empirical evidence to a justification for the prediction. Student S's response highlights an important point that justifies separating the scoring of information from the scoring of reasoning. Carbon dioxide and water form carbohydrates and oxygen. Validity must be concerned not only with the technical quality of educational data, but also with the social and educational consequences of data interpretation. Consequently, confidence in the validity of inferences requires explicit reference to the assumptions on which those inferences are based. 1992. This jar also works as a catalyst to speed up the process by causing evaporation of H2O through incomplete vaporization. Black, P. & William, D. (1998). and learning. What are the other ways to increase the rate of a chemical reaction? Each individual in the group is required to keep extensive records of the group's work, especially documenting the evolution of their final research question from the several questions originally proposed. For instance, in the context of planning the inquiry, students pose questions for investigation. Developing a scoring rubric begins with a description of the performance standard for scientifically literate adults. A fourth-grade student might respond to the exercise in the following way: The plant could live. SCIENCE CONTENT: The 5-8 Physical Science Content Standard includes an understanding of motions and forces. It follows that the processes used to assess student achievement must be fair to all students. . This is one way in which the deleterious effects of bias can be avoided. teaching and learning,described as assessment for learning (AfL),or formative assessment.Here the focus is on assessment of learning,or summative assessment,which is used to summarise what pupils know or can do at certain times in order to report achievement and progress. Carlson, P.J. Assessment is the ongoing process of gathering, analysing and reflecting on evidence to make informed judgments about the achievement or capabilities of individuals and cohorts. When teachers treat students as serious learners and serve as coaches rather than judges, students come to understand and apply standards of good scientific practice. Ms. M. asks the students to write answers to the questions she posed; she suggests that the students use diagrams as a part of the responses. No surprise then that problem-based learning and inquiry-based learning play an increasing role in the kinds of learning tasks that teachers set for their students. Educational Researcher, 23 (2): 13-23. The liquid water evaporates continuously. Finally, students present and defend their revised questions to the class. The extent to which the management system increased teacher responsibility and led to changes in the science programs that could influence science achievement must also be measured. The second example is about the ability to inquire, which also requires a body of scientific information and the competence to reason with it to conceptualize, plan, and perform investigations. Andover, MA: The Network, Inc. Messick, S. 1994. It often contributes to pivotal decisions that will affect students’ futures. That report also includes data that have been collected and preliminary analysis. The physicist, the chemist, the biologist, and the physician all have a highly sophisticated understanding of respiration. Plants need water to photosynthesize. Perhaps the student does not know about respiration or that the processes are complementary. Finally, a well-crafted justification for any prediction about the plant in the jar demonstrates reasoning characterized by a succession of statements that follow one another logically without gaps from statement to statement. After presenting research questions to the class, students form the research groups, which come to agreement on a question to investigate and begin developing a preliminary plan for conducting the investigation. Conversations among a teacher and students about assessment tasks and the teacher's evaluation of performance provide students with necessary information to assess their own work. These changes in measurement theory and practice are reflected in the assessment standards. If assessment is to be used in classrooms to help students learn, it must be transformed in two fundamental ways. Exercises of this sort are difficult to design and are a challenge to score. Statistical techniques require that both sexes and different racial and ethnic backgrounds be included in the development of large-scale assessments. In conclusion, in a jar closed from CO2and water, plants use up their resources quickly, preventing the equation CO2 + H2O-> C6H12 O6 and O2 and, therefore, energy from carbohydrates. ASSESSMENT ACTIVITY: Students respond to questions about frames of reference with extended written responses and diagrams. The content standards are stated in terms of understandings and abilities; therefore, the first example is about understanding the natural world. Imagine an insect and a spider on a lily pad floating down a stream. Assessment practices also communicate what is important and what is valued in science education. By identifying essential characteristics of exemplary assessment practices, the standards serve as guides for developing assessment tasks, practices, and policies. The justification should be explicit about the assumptions that underlie it and even contain some speculation concerning the implications of making alternative assumptions. Even then, the general public, as well as professionals, should demand open and understandable descriptions of how the inferences were made. Such understanding requires knowing concepts, principles, laws, and theories of the physical, life, and earth sciences, as well as ideas that are common across the natural sciences. Performance-based assessment tools, informed by children's ongoing behaviors and work products under unstructured and semi-structured circumstances, provide formative assessment of children's learning and can be used by teachers to design new learning experiences to better support and challenge learners in science and other areas. Involving students in the assessment process increases the responsibilities of the teacher. The effectiveness of the selected examples. In the vision of science education described by the Standards, teachers use the assessment data in many ways. Evidence for the quality of a student's ability to reason scientifically comes from the rationale for the student's own research question and from the line of reasoning used to progress from patterns in the collected data to the conclusions.
