PREFACE

Consistent with the State Board of Education Rules, Regulations, and Minimum Standards, the Tennessee Science Curriculum Framework, K-12, was developed by a statewide committee of science educators. A concerted effort was made to ensure that the revised document is in alignment with the national science education standards developed by the National Research Council. It is designed to serve as a foundation for developing a comprehensive science program that includes both process and content. This document is provided as a descriptive tool, rather than a prescriptive device, to be used to identify concepts which all students need to know. Each local school system is required to implement the Tennessee Science Curriculum Framework, K-12 beginning with the 1997-98 school year. Three science credits are required for graduation. These credits must be drawn from both the life sciences and the physical sciences. All science courses require a laboratory component. Successful implementation of the science framework requires the active participation of students as they explore the natural world. Content and process must merge so that students understand scientific concepts and their applications in technology, as well as make connections among science, technology and society. The State Department of Education expects to have sufficient computer and print copies of the framework available to each school system to facilitate the correlation of performance objectives with the stated concepts and content. PHILOSOPHY The Tennessee Science Curriculum Framework Committee believes that a science framework should help science educators at all levels understand and appreciate the reforms that are needed. A framework should organize, specify, and integrate the content, themes, processes, and attitudes of science for all of Tennessee's public school teachers. It should provide examples of what students should know and be able to do in science at all levels, K-12. The framework should provide an umbrella under which Local Educational Agencies (LEA's) can organize and specify the components of their science curriculum. Moreover, it should provide direction and guidance to districts and schools as they bring their science curriculum in alignment with national and state curriculum reform efforts. It is essential that the framework be descriptive and not prescriptive. It should be a document that is evolving and changing as new ideas and experiences become known. We believe that a Tennessee Science Curriculum Framework should be a document that assists LEA's in translating content, teaching, and assessment standards into the science program. A framework should provide goals and a road map for achieving those goals. The Tennessee Science Curriculum Framework will help to insure that Tennessee students will have rich and meaningful science experiences that will produce a citizenry that is scientifically literate. Curriculum guides, on the other hand are more detailed than a framework, providing content synopses and activities for schools, and representing the unique flavor and need of the community. Curriculum guides may be developed at the state or local level. Classroom connectors require significant preparation time, due to greater curricular specificity than that required for the curriculum guide. However, they provide a more complete presentation of content and a more detailed set of instructions for activities. Both of these emphases are desirable for a complete development of the performance objectives, and attainment of the desired response(s) on the assessment activities. Classroom connectors may be developed at the state or local level. VISION STATEMENT FOR FRAMEWORK Science is a way to explore and understand the world. It is a response to curiosity. Through a basic knowledge of science, people learn about the world, its technology, its environment, and the decisions that must be made to preserve the planet. Science strengthens the ability to think reactively and objectively. A scientifically literate person makes informed decisions and has rich and meaningful experiences in the natural world at an early age. If students are to construct meaning from experience, they must be provided with the time and the opportunity to experience the natural world. These experiences help to develop the skills of reading, writing and numeration as the child makes observations, collects data, orders and classifies objects, manipulates variables, and communicates findings (orally and in writing) to others. Science is the cornerstone of early achievement. Using the natural curiosity of a child as the building block, the skills of reading, writing, and numeration are enhanced. Science is a capstone for living. Ethical decisions are often decided by an understanding of scientific principles involved. Science is a way of knowing. The practice of science builds on experiences and is an important way new knowledge is discovered. Science is a way of thinking. It is constantly questioning, seeking alternative solutions, looking for a better way. Science is a way of doing. It is experimenting, finding and evaluating new ideas, new solutions. Doing science is a life-long adventure that positively affects all people in their daily lives and careers. As students do science they see the relationship between science and other areas of human understanding. Science instruction is relevant and recognizes the different ways and settings in which people learn. Science enhances curiosity, excitement, adventure, wonder, and joy. There are certain underlying principles supporting the framework vision for science education in Tennessee. These have emerged from several major scientific, educational, and business groups, as well as government agencies, on ways to improve science teaching and learning. They include:
NATIONAL AND STATE GOALS OF EDUCATION AND SCIENCE EDUCATION
NATIONAL EDUCATION GOALS The National Education Goals codify into law eight goals and their objectives. The goals state that, by the year 2000:
  1. all children in America will be ready to learn;
  2. the high school graduation rate will increase to at least 90 percent;
  3. American students will leave grades 4, 8, and 12 having demonstrated competency over challenging subject matter including English, math, science, arts, foreign languages, history and geography, civics and government, and economics;
  4. the NationUs teaching force will have access to programs for the continued improvement of their professional skills and the opportunity to acquire the knowledge and skills needed to instruct and prepare all American students for the next century;
  5. U. S. students will be first in the world in math and science achievement;
  6. every American will be literate and will possess the knowledge and skills necessary to compete in a global economy;
  7. every school in America will be free of drugs, alcohol, and violence and will offer a disciplined environment conducive to learning;
  8. every school will promote partnerships that will increase parental involvement and participation in promoting the social, emotional, and academic growth of children.
NATIONAL GOALS OF SCIENCE The goals for school science that underlie the National Science Education Standards as produced in the 1994 draft are designed to educate students who are able to:
  1. use scientific principles and processes appropriately in making personal decisions;
  2. experience the richness and excitement of knowing about and understanding the natural world;
  3. increase their economic productivity; and
  4. engage intelligently in public discourse and debate about matters of scientific and technological concern.
Achieving these primary goals of science education also should result in students who are aware of careers in science, technology, and the health professions. Achieving these goals is possible when all citizens are scientifically literate. The standards for content define what the scientifically literate person should understand and be able to do after 13 years of schooling. The standards for assessment, teaching, program, and system describe the conditions necessary to achieve the goal of scientific literacy for all students, including opportunities for students to learn and for teachers to teach. Implementation of the standards calls for schools to be centers for inquiry and for an educational system that supports such schools and teachers. Students could not achieve the standards in most of todayUs schools. Schools that implement the standards will have students learning science by actively engaging in inquiries of interest and importance to them. Such students will establish a knowledge base for understanding science. Teachers will be empowered to make decisions about what students learn and how they learn it and about how resources are allocated. Teachers and students together will be members of a community focused on learning science and nurtured by a supportive education system.
GOALS OF SCIENCE IN TENNESSEE
Science education is closely related to the goals of education set forth by the State Board of Education. The Rules, Regulations, and Minimum Standards require that a continuous program in science be provided for every child. Goals of Science in Tennessee will enable students to:
  1. demonstrate the processes of science by posing questions and investigating phenomena through language, methods and instruments of science;
  2. acquire scientific knowledge by applying concepts, theories, principles and laws from life science, physical science, earth/space science, and environmental science;
  3. demonstrate ways of thinking and acting inherent in the practice of science and exhibit an awareness of the historical and cultural contributions to the enterprise of science; and
  4. demonstrate positive attitudes toward science in solving problems and making personal decisions about issues affecting the individual, society and the environment.
INTRODUCTION
This framework is designed to help science educators at all levels understand and appreciate a new dynamic in science learning. Its significance lies in the fact it requires actively engaging students in learning about the natural and technological world in which they live. The framework provides an opportunity for innovative approaches to science education. Innovation is especially important in a field that is constantly adapting to new advances in basic knowledge in such areas as medicine, engineering and technology. To be prepared for the twenty-first century, students must be able to apply the principles and practices of science. For all students to achieve scientific literacy, it is critical that schools:
WHAT IS SCIENCE?
Science is the component of the school curriculum in which student inquiry and discovery can develop and flourish. Science instruction encourages questioning, examining, probing, and exploring; it allows students to cultivate personal strategies for learning. Science is, above all, a problem-solving activity that seeks answers to questions by collecting and analyzing data offering explanations of naturally occurring events. The knowledge that results from scientific problem solving is most useful when it is organized into concepts, generalizations, and unifying principles, which lead to further investigations of objects and events in the environment. Science is practiced in the context of human culture, and therefore, dynamic interactions occur among science, technology, and society. Four components of science education - process of science, unifying concepts of science, habits of mind, and science in society - are critically important to instruction in science. SCIENCE SHOULD BE A POSITIVE EXPERIENCE FOR ALL STUDENTS In order to function in an information age, all students must have an understanding of scientific ways of thinking and science knowledge. Learning science helps develop critical thinking skills and gives practice in the use of evidence in decision making. All citizens use a basic understanding of science and technology to make good decisions about various social issues that affect their lives. Therefore, the most significant goal of science education is to improve the quality of life of the nationUs children so that they will be well rounded, clear-thinking, scientifically literate citizens. As this goal is accomplished the best foundation for producing scientists will be laid, and the production of scientists is clearly seen as a need in our society. EMPHASIZING UNDERSTANDING OVER CONTENT COVERAGE Recent research in science teaching and learning provides clear evidence that most students are memorizing facts rather than becoming scientifically literate. There is now a large body of research-based knowledge compiled over a long period of time that supports the belief that the Rfacts onlyS approach to science teaching when compared to the Rhands-onS and upper cognition level approaches is practically and developmentally inappropriate. Validation of this position can be shown by a review of numerous studies done a minimum of ten years ago that compared the hands-on approach to the traditional textbook approach (Shymansky, Kyle, and Alport, 1982). The particular hands-on programs studied were the Elementary Science Study (ESS), Science Curriculum Improvement Study (SCIS), and the Science A Process Approach (SAPA). A review of these studies will indicate a likeness to the intent of the Tennessee Science Curriculum Framework, K-12. Some twenty studies were analyzed with regard to academic achievement. The authors concluded: Contrary to a popular notion that hands-on, activity-based science curricula lacked a potent academic content base, we found that students using ... programs actually outscored students in the more traditional classrooms - by as much as 34 percentile points. Attitude toward the hands-on approach with its higher cognition level focus was investigated through the analysis of 21 studies. The findings were: The studies approached the question of attitude in three ways: (1) attitude toward the new course, (2) attitude toward science, and (3) attitude toward self. In each of these categories, student attitudes were more positive toward the new programs than the traditional ones, with differences ranging from 3 to 20 percentile points. Process skills development was also analyzed in the review. The results of the investigation were: The new elementary science curriculum placed great emphasis on the development of process skills, including observing, inferring, interpreting data, hypothesizing, and graphing. We analyzed the results of 13 studies that focused on process skill development in new curricula versus traditional classrooms. In the three elementary science curricula we studied, new curricula students score at least 18 percentile points higher than traditional class students on measures of process development. In summary the authors reported: Our quantitative synthesis of the research clearly shows that students in those programs achieved more, liked science more, and improved their skills more than did students in traditional, textbook-based classrooms. The report for the hands-on curricula is impressive. In another study (Bredderman, 1985), supported by the National Science Foundation, the effects of the same three programs on student outcomes were assessed by quantitatively combining the results of 57 reported evaluations of the programs. Only evaluations in which controls were used were included. In summary: It appears that the programs designed to encourage the use of laboratory science, starting in the elementary school years, do in fact result in improved student performance in a number of valued curricular areas. Based on the available research evidence, it also appears that the use of inquiry programs increases the amount of student-laboratory activity and decreases the amount of teacher talk in the classrooms, as intended (Bredderman, 1984). Although the research quoted refers to Rhands-on scienceS programs prepared for elementary school age students, there are a number of similar programs for secondary school students. Among these are Physical Science Study Committee (PSSC), Project Physics, CHEM Study, and Biological Science Curriculum Study (BSCS). There is every reason to believe that a similar research result would be found for secondary school students like the one found for elementary school students. Students of all ages ask a great many questions. Thus, most students need to engage in activities requiring Rhigher order thinking,S in order to find answers for those questions.

THE SCIENCE EDUCATOR'S ROLE IN FACILITATING STUDENT LEARNING

The role of the science educator is that of a facilitator of learning rather than that of a primary dispenser of knowledge. Information should be presented in the context of a rich learning environment, in which the student is an active participant. Rather than telling the students what they are to learn, an environment should be created in which the student can be active in acquiring knowledge through the process of experimentation and discourse. The science educator is to engage students in problem solving by asking probing questions, promoting inquiry, guiding discussion, and creating situations and scenarios that beg for exploration and explanation. Facilitating science learning also requires the science educator to have a working knowledge of resources, which may include curricular materials, technology, community members, professional colleagues, and institutional resources such as museums, science centers, or nature centers. For science educators to be successful, support must be made available both within the school and from the broader professional community. Educators must have opportunities to exchange ideas and experiences with colleagues, to reflect on their teaching, to read research, and to contribute as part of a research team.

SIGNIFICANT FRAMEWORK INCLUSIONS The Tennessee Science Curriculum Framework, K-12 is an attempt to change the way the Tennessee community of learners thinks about science. The community of learners includes students, families, educators, governmental organizations, businesses, industries, political leaders and all participants in society. The framework promotes learning science by doing science. It is a thoughtful response to a variety of reforms, beginning with the Tennessee landmark Education Improvement Act (EIA) of 1992. This document has also incorporated ideas from the National Science Education Standards Project, American Association for Advancement of ScienceUs (AAAS) Project 2061, and National Science Teachers AssociationUs (NSTA) Scope Sequence and Coordination Project, as well as other state and national curriculum reform initiatives. The standards outlined in this framework can be used by Tennessee educators to make the decisions necessary for effective science programs at the elementary, middle and secondary levels. The framework is organized around four components: Process of Science, Unifying Concepts of Science, Habits of Mind, and Science in Society. These four components are the foundation of the K-12 science curriculum in Tennessee. In each component, the generalized standards are written to accommodate a variety of instructional strategies and resources, yet they are pointed at specific concepts and skills that students should know and be able to do. Local curricula should be developed from this framework beginning with the preparation of performance objectives that describe precisely what intended outcomes related to the benchmark have been selected as educational focal points. The intent of the document is to increase studentsU understanding of essential scientific concepts by promoting activities that engage students in doing science, using available technological tools, and rationally thinking about the natural world. To this end, the Tennessee Science Curriculum Framework, K-12 gives directions for an innovative approach to science education. It provides a philosophical foundation and a curricular framework from which educators may construct comprehensive science education programs for elementary, middle, and high schools. This framework is a document developed by science teachers for science teachers. Therefore, this document is dedicated to the science teachers of the State of Tennessee. TENNESSEE'S FOUR COMPONENTS OF SCIENCE EDUCATION 1. Process of Science The processes of science enable students to pose questions and investigate phenomena through the language, methods, and instruments of science. Common science process themes include observing, questioning, collecting data, analyzing, explaining, and communicating. The process of science follows no single pathway but involves imagination, inventiveness, experimentation and logic, and evidence to support results. Once a question is posed, the search for answers follows a purposeful sequence of experimentation, data collection, analysis, and evaluation of conclusions, perhaps leading to new questions. Technology provides tools and techniques that improve studentsU skills in measuring, calculating, recording, analyzing, modeling, and communicating. Hands-on explorations provide students with opportunities to use materials in new and concrete situations, to analyze results for greater understanding, to synthesize new ideas with what has been previously learned, and to evaluate how this new knowledge will be of practical use in their lives. Students may work in teams and share findings with others, but each individual should contribute to the group. 2. Unifying Concepts Students acquire scientific knowledge by applying concepts, theories, principles and laws from life/environmental, physical and earth/space sciences. Any field of knowledge is more than an accumulation of isolated facts and ideas. In science, particularly, recurrent themes and concepts occur as our knowledge and understanding of the phenomena encountered in the natural world increase. Unifying themes connecting the science disciplines are scale and model, form and function, organization, interactions, change, and conservation. These themes provide the framework into which one can fit new discoveries and insights, thus making a complex field of knowledge more comprehensible and meaningful. Utilizing these themes to organize instruction in science will ultimately provide students with a more coherent and integrated understanding of the world in which they live. This organization is especially important as scientific knowledge continues to increase at an exponential rate. 3. Habits of Mind Students must be able to demonstrate ways of thinking and acting inherent in the practice of science and to exhibit an awareness of the historical and cultural contributions to the enterprise of science. Habits of mind include historical and cultural perspectives, assumptions, estimations and computations, scientific methods, an understanding of science and technology, and an appreciation of creative enterprises. Science is a creative process that attempts to discover and understand. Science questions all things and opens itself to continual scrutiny and modification. Science is carried out according to informed rules and assumptions. The rules and assumptions have developed over centuries from the experiences of those who have attempted to understand the natural world. However, as scientific knowledge grows, students should be prepared to alter their points of view. In this way, science is a never ending process of discovery, interpretation, and evaluation. 4. Science in Society The student should be able to develop positive attitudes toward science in solving problems and making personal decisions about issues affecting the individual, the society and the environment. Attitudes, personal needs, career goals, societal needs, economics, and politics all contribute to the role of science in society. Over the last several decades, the rate of scientific knowledge acquisition has increased dramatically. Fields such as medicine, space science, particle physics, and organic chemistry continue to produce information faster than it can be processed by any individual or group. The demand for science to investigate and technology to solve many of the worldUs problems has served to further accelerate this growth of knowledge. The achievements of science and technology influence society, which either supports or limits the progress of science and technology. Therefore, the science curriculum should be structured to develop awareness of the interactions of science, technology, and society. To meet these challenges presented by society, it is necessary for the science curriculum of our schools to address the attitudes, processes, tools, knowledge, and societal implications of science. This comprehensive approach to science education requires that learners receive essential readiness skills needed to become scientifically literate. Such skills go beyond learning, they give individuals a foundation for making sound decisions, understanding recent scientific advances and their implications, preparing to enter the job market, and developing a feeling of control over their lives. TENNESSEE'S THEMES Themes should be a major emphasis of the science curriculum. The themes of science are large ideas that connect and integrate the traditional science disciplines and incorporate other subjects, such as technology, mathematics, and social studies. Themes presented in this framework can be used as a vehicle to present an interdisciplinary view of science.

PROCESS OF SCIENCE

GOAL: To enable students to demonstrate the process of science by posing questions and investigating phenomena through language, methods and instruments of science. THEME: 1.1 OBSERVING -
The senses are used to develop an awareness of an event or object and the properties thereof. THEME: 1.2 QUESTIONING - The development of an inquisitive mind and the effective use of questioning techniques furthers the acquisition of information. THEME: 1.3 COLLECTING DATA - The acquiring, recording, arranging and storing of information must be performed in a complete, accurate, concise, and user friendly manner. THEME: 1.4 ANALYZING - Data should be examined to find patterns and relationships that may suggest cause and effect or support inferences and hypotheses. THEME: 1.5 EXPLAINING - Phenomena and related information are made understandable through discussion that culminates in a higher level of learning. THEME: 1.6 COMMUNICATING - An essential aspect of science is the act of accurately and effectively conveying oral, written, graphic or electronic information from the preparer to the user.

UNIFYING CONCEPTS OF SCIENCE

GOAL: To enable students to acquire scientific knowledge by applying concepts, theories, principles and laws from life/environmental, physical and earth/space science. THEME: 2.1 SCALE AND MODEL -
The development of models provides a conceptual bridge between the concrete and the abstract, while the use of scales allows for a comparison of differences in magnitude between the model and the desired form.

THEME: 4.6 POLITICS - Basic scientific concepts should be available to all individuals enabling each to make logical decisions for himself or herself and others. A FRAMEWORK FORMAT EXPLANATION The learning process proposed by the Tennessee Science Curriculum Framework, K-12 is one that depicts a narrowing of the community of learnerUs concentration as the educational focus moves from the Goal to the Benchmark, by way of the Theme and Standard. The intent of the lowest level of the process, the Benchmark, is to provide a point of reference toward which instruction can be aimed and finally to provide a target whose degree of attainment can be measured by ordinary assessment activities. In practice, one or more performance objectives that relate directly to the Benchmark must be teacher constructed for inclusion in the lesson plan. Each performance objective written by the teacher identifies a segment of content related to the Benchmark that is to be taught and also provides the root for an assessment activity. The importance of the selection of the performance objectives is significant in todayUs world because of the value placed on scores such as those obtained from the Tennessee Comprehensive Assessment Program test. More often than in the past, standardized tests are based on questions that address the upper levels of cognition. In the case of BloomUs Taxonomy of Education Objectives, the upper levels of cognition would be the Comprehension, Application, Analysis, Synthesis, and Evaluation levels rather than the Knowledge level. Care should be taken in designing the performance objectives in the classroom to address the various higher levels of cognition. This instructional strategy prepares the individual learner with a science background that is most likely to improve the studentUs quality of life, while at the same time better preparing the student to be more competitive on standardized tests. Definitions that will help the science educator understand the educational thrust of the Tennessee Science Curriculum Framework, K-12 are: Goal A goal is the identification of the general direction toward which the community of learners will direct their education efforts. Theme A theme is a statement which identifies a topic to be given special investigative consideration by the community of learners. Standard A standard is a segment of information drawn from the theme that the community of learners perceives to have recognized and lasting value. Benchmark A Benchmark is an instructional point of reference or target whose degree of attainment can be measured by analysis of the success and/or lack of success in meeting the related performance objectives. Performance Objective A performance objective is a statement that describes precisely what outcome related to the benchmark has been selected as an educational focal point. In general, performance objectives begin with "The learner will be able to" and conclude with an outcome that is measurable by completion of an assessment activity. Performance objectives should be organized in ascending order of cognition level, thus determining the order of content presentation. Assessment Activity An assessment activity is a test item or a more complex problematic situation where the student is required to demonstrate the ability to reach a specified outcome that allows for judgment of the studentUs effort as to accuracy and/or value.
