Students discover new concepts through guided instruction and confirm their understanding in an interactive, feedback-rich environment. Scientific inquiry skills are embedded in the direct instruction, wherein students learn to ask scientific questions, form and test hypotheses, and use logic and evidence to draw conclusions about the concepts. A variety of activities encourage students to think scientifically. Lab and Project activities reinforce critical thinking, writing, and communication skills and help students develop a deeper understanding of the nature of science and engineering. Virtual Lab activities allow students to engage in investigations that require long periods of observation at remote locations and to explore simulations that scientists use to test predictions.
In Discussions, students compare their lab results and exchange ideas about their investigations. Practice and Explore activities provide additional opportunities for students to apply learned concepts and practice their writing and scientific reasoning skills. This course is built to state standards. Course Materials.

Consistency of performance is also established through repeated observations. Data-collection methods can take many forms. Each has advantages and disadvantages. The choice among them is usually The choice of assessment form should be consistent with what one wants to measure and to infer. However, to serve the intended purpose, the choice of assessment form should be consistent with what one wants to measure and to infer. It is critical that the data and their method of collection yield information with confidence levels consistent with the consequences of its use. Public confidence in educational data and their use is related to technical quality. 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.
Assessment Standard D Assessment practices must be fair. 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. Large-scale assessments must use statistical techniques to identify potential bias among subgroups. Assessment tasks must be appropriately modified to accommodate the needs of students with physical disabilities, learning disabilities, or limited English proficiency. Assessment tasks must be set in a variety of contexts, be engaging to students with different interests and experiences, and must not assume the perspective or experience of a particular gender, racial, or ethnic group. It follows that the processes used to assess student achievement must be fair to all students.
This is not only an ethical requirement but also a measurement requirement. If assessment results are more closely related to gender or ethnicity than to the preparation received or the science understanding and ability being assessed, the validity of the assessment process is questionable. Those who plan and implement science assessments must pay deliberate attention to issues of fairness.
National Science Education Standards. Statistical techniques require that both sexes and different racial and ethnic backgrounds be included in the development of large-scale assessments. Bias can be determined with some certainty through the combination of statistical evidence and expert judgment. For instance, if an exercise to assess understanding of inertia using a flywheel results in differential performance between females and males, a judgment that the exercise is biased might be plausible based on the assumption that males and females have different experiences with flywheels. Whether assessments are large scale or teacher conducted, the principle of fairness requires that data-collection methods allow students with physical disabilities, learning disabilities, or limited English proficiency to demonstrate the full extent of their science knowledge and skills. The requirement that assessment exercises be authentic and thus in context increases the likelihood that all tasks have some degree of bias for some population of students.
Some contexts will have more appeal to males and others to females. If, however, assessments employ a variety of tasks, the collection will be "equally unfair" to all. This is one way in which the deleterious effects of bias can be avoided. Assessment Standard E The inferences made from assessments about student achievement and opportunity to learn must be sound. When making inferences from assessment data about student achievement and opportunity to learn science, explicit reference needs to be made to the assumptions on which the inferences are based. 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.
Making inferences involves looking at empirical data through the lenses of theory, personal beliefs, and personal experience. Making objective inferences is extremely difficult, partly because individuals are not always aware of their assumptions. Consequently, confidence in the validity of inferences requires explicit reference to the assumptions on which those inferences are based. For example, if the science achievement on a large-scale assessment of a sample of students from a certain population is high, several conclusions are possible. Little confidence can be placed in any of these conclusions without clear statements about the assumptions and a developed line of reasoning from the evidence to the conclusion. The level of confidence in conclusions is raised when those conducting assessments have been well trained in the process of making inferences from educational assessment data. Even then, the general public, as well as professionals, should demand open and understandable descriptions of how the inferences were made.
Assessments Conducted by Classroom Teachers Teachers are in the best position to put assessment data to powerful use. In the vision of science education described by the Standards, teachers use the assessment data in many ways. Some of the ways teachers might use these data are presented in this section. Improving Classroom Practice [See Teaching Standard C] Teachers collect information about students' understanding almost continuously and make adjustments to their teaching on the basis of their interpretation of that information. They observe critical incidents in the classroom, formulate hypotheses about the causes of those incidents, question students to test their hypotheses, interpret student's responses, and adjust their teaching plans. Planning Curricula Teachers use assessment data to plan curricula. Some data teachers have collected themselves; other data come from external sources. The data are used to select content, activities, and examples that will be incorporated into a course of study, a module, a unit, or a lesson.
Teachers use the assessment data to make judgments about The developmental appropriateness of the science content. Student interest in the content. The effectiveness of activities in producing the desired learning outcomes. The effectiveness of the selected examples. The understanding and abilities students must have to benefit from the selected activities and examples. Planning for assessment is integral to instruction. Assessments embedded in the curriculum serve at least three purposes: to determine the students' initial understandings and abilities, to monitor student progress, and to collect information to grade student achievement.
Assessment tasks used for those purposes reflect what students are expected to learn; elicit the full extent of students' understanding; are set in a variety of contexts; have practical, aesthetic, and heuristic value; and have meaning outside the classroom. Before students can do this, they need to understand the goals for learning science. The ability to self-assess understanding is an essential tool for self-directed learning.
Through self-reflection, students clarify ideas of what they are supposed to learn. They 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. Developing self-assessment skills is an ongoing process throughout a student's school career, becoming increasingly more sophisticated and self-initiated as a student progresses.
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. In concert with opportunities to apply it to individual work and to the work of peers, that information contributes to the development of students' self-assessment skills. By developing these skills, students become able to take responsibility for their own learning. Teachers have communicated their assessment practices, their standards for performance, and criteria for evaluation to students when students are able to Select a piece of their own work to provide evidence of understanding of a scientific concept, principle, or law—or their ability to conduct scientific inquiry. Explain orally, in writing, or through illustration how a work sample provides evidence of understanding.
Critique a sample of their own work using the teacher's standards and criteria for quality. Critique the work of other students in constructive ways. Involving students in the assessment process increases the responsibilities of the teacher. Teachers of science are the representatives of the scientific community in their classrooms; they represent a culture and a way of thinking that might be quite unfamiliar to students. As representatives, teachers are expected to model reflection, fostering a learning environment where students review each others' work, offer suggestions, and challenge mistakes in investigative processes, faulty reasoning, or poorly supported conclusions. A teacher's formal and informal evaluations of student work should exemplify scientific practice in making judgments.
The standards for judging the significance, soundness, and creativity of work in professional scientific work are complex, but they are not arbitrary. In the work of classroom learning and investigation, teachers represent the standards of practice of the scientific community. 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.
