National Science Education Standards
Content Standards
Standard A: Students develop the abilities necessary to do scientific inquiry and understandings about scientific inquiry.
Standard B: Structure and properties of matter.
Standard E: Students develop abilities of technological design and understandings about science and technology.
Standard F: Students develop an understanding of personal and community health
Standard G: Students develop an understanding of science as a human endeavor and the nature of scientific knowledge.
Teaching Standards
Standard A: Teachers develop a framework of yearlong and short-term goals for students. Teachers select content and adapt and design curricula to meet the interests, knowledge, understanding, abilities, and experiences of students. Teachers select teaching and assessment strategies that support the development of student understanding and nurture a community of science learners.
Standard B: Teachers focus and support inquiry while interacting with students. Teachers orchestrate discourse among students about scientific ideas. Teachers challenge students to accept and share responsibility for their own learning. Teachers encourage and model the skills of scientific inquiry, as well as the curiosity openness to new ideas and data, and skepticism that characterize science.
Standard C: Teachers use multiple methods and systematically gather data about student understanding and ability. Teachers analyze assessment data to guide teaching and guide the students in self-assessment.
Standard D: Teachers structure the time available so that students are able to engage in extended investigations. Teachers create a setting for student work that is flexible and supportive of science inquiry. Teachers make the available science tools, materials, media, and technological resources accessible to students. Teachers identify and use resources outside the school and provide a safe working environment. Teachers engage students in designing the learning environment.
Standard E: Teachers display and demand respect for the diverse ideas, skills, and experiences of all students. Teachers enable students to have a significant voice in decisions about the content and context of their work and require students to take responsibility for the learning of all members of the community. Teachers nurture collaboration among students. Teachers model and emphasize the skills, attitude, and values of scientific inquiry.
Assessment Standards
Standard A: Assessments are deliberately designed and have explicitly stated purposes.
Standard C: Assessment tasks are authentic. Students have adequate opportunity to demonstrate their achievements.
Standard D: Assessments are fair and do not assume the perspective of a particular gender, racial, or ethnic group.
