Part 1 The Teaching FrameworkIntroductionBackgroundThe curriculum described in Foundation for the Atlantic CanadaScience Curriculum was planned and developed collaborativelyby regional committees. The process for developing thecommon science curriculum for Atlantic Canada involvedregional consultation with the stakeholders in the educationsystem in each Atlantic province. The Atlantic Canada sciencecurriculum is consistent with the science framework described inthe pan-Canadian Common Framework of Science LearningOutcomes K to 12.The development of these curricula involved further revision ofthe Atlantic Canada Science Curriculum for Chemistry 11 andChemistry 12, in consultation with educators in New Brunswickover a 3-year period (as listed in the Acknowledgements).RationaleThe aim of science education in the Atlantic provinces is todevelop scientific literacy.Scientific literacy is an evolving combination of the sciencerelated attitudes, skills, and knowledge students need todevelop inquiry, problem-solving, and decision-making abilities;to become life-long learners; and to maintain a sense of wonderabout the world around them. To develop scientific literacy,students require diverse learning experiences which provideopportunity to explore, analyze, evaluate, synthesize,appreciate, and understand the interrelationships amongscience, technology, society, and the environment that will affecttheir personal lives, their careers, and their future.9Chemistry 111 – 112 Curriculum

Part 1 The Teaching FrameworkProgram Design & ComponentsLearning and TeachingScienceWhat students learn is fundamentally connected to how they learn it.The aim of scientific literacy for all has created a need for new forms ofclassroom organization, communication, and instructional strategies.The teacher is a facilitator of learning whose major tasks include: creating a classroom environment to support the learning andteaching of science designing effective learning experiences that help studentsachieve designated outcomes stimulating and managing classroom discourse in support ofstudent learning learning about and then using students‟ motivations, interests,abilities, and learning styles to improve learning and teaching analyzing student learning, the scientific tasks and activitiesinvolved, and the learning environment to make ongoinginstructional decisions selecting teaching strategies from a wide repertoireEffective science learning and teaching take place in a variety ofsituations. Instructional settings and strategies should create anenvironment which reflects a constructive, active view of the learningprocess. Learning occurs not by passive absorption, but rather asstudents actively construct their own meaning and assimilate newinformation to develop new understanding.The development of scientific literacy in students is a function of thekinds of tasks they engage in, the discourse in which they participate,and the settings in which these activities occur. Students‟ dispositiontowards science is also shaped by these factors. Consequently, theaim of developing scientific literacy requires careful attention to all ofthese facets of curriculum.Learning experiences in science education should vary and includeopportunities for group and individual work, discussion among studentsas well as between teacher and students, and hands-on/minds-onactivities that allow students to construct and evaluate explanations forthe phenomena under investigation. Such investigations and theevaluation of the evidence accumulated, provide opportunities forstudents to develop their understanding of the nature of science andthe nature and status of scientific knowledge.10 Chemistry 111 – 112 Curriculum

Part 1 The Teaching FrameworkThe Three Processes ofScientific LiteracyInquiryAn individual can be considered scientifically literate whenhe/she is familiar with, and able to engage in, three processes:inquiry, problem solving, and decision making.Scientific inquiry involves posing questions and developingexplanations for phenomena. While there is general agreementthat there is no such thing as the scientific method, studentsrequire certain skills to participate in the activities of science.Skills such as questioning, observing, inferring, predicting,measuring, hypothesizing, classifying, designing experiments,collecting data, analyzing data, and interpreting data arefundamental to engaging in science. These activities providestudents opportunity to understand and practice the process oftheory development in science and the nature of science.Problem SolvingThe process of problem solving involves seeking solutions tohuman problems. It consists of the proposing, creating, andtesting of prototypes, products and techniques in an attempt toreach an optimum solution to a given problem.Decision MakingThe process of decision making involves determining what we,as citizens, should do in a particular context or in response to agiven situation. Decision-making situations are not onlyimportant in their own right. They also provide a relevantcontext for engaging in scientific inquiry and/or problem solving.11 Chemistry 111 – 112 Curriculum

Part 1 The Teaching FrameworkMeeting the Needs of AllLearnersFoundation for the Atlantic Canada Science Curriculum stresses theneed to design and implement a science curriculum that providesequal opportunities for all students according to their abilities, needsand interests. Teachers must be aware of and make adaptations toaccommodate the diverse range of learners in their class. In order toadapt to the needs of all learners, teachers must create opportunitiesthat would permit students to have their learning styles addressed.As well, teachers must not only remain aware of and avoid gender andcultural biases in their teaching, they must strive to actively addresscultural and gender stereotyping regarding interest and success inscience and mathematics. Research supports the position that whenscience curriculum is made personally meaningful, and socially andculturally relevant, it is more engaging for groups traditionally underrepresented in science, and indeed, for all students.When making instructional decisions, teachers must considerindividuals‟ learning needs, preferences and strengths, and theabilities, experiences, interests, and values that learners bring to theclassroom. Ideally, every student should find his/her learningopportunities maximized in the science classroom.While this curriculum guide presents specific outcomes for each unit, itmust be acknowledged that students will progress at different rates.Teachers should provide materials and strategies that accommodatestudent diversity, and validate students when they achieve theoutcomes to the maximum of their abilities.It is important that teachers articulate high expectations for all studentsand ensure that all students have equitable opportunities to experiencesuccess as they work toward the achievement of designatedoutcomes. A teacher should adapt classroom organization, teachingstrategies, assessment practices, time, and learning resources toaddress students‟ needs and build on their strengths. The variety oflearning experiences described in this guide provides access for awide range of learners. Similarly, the suggestions for a variety ofassessment practices provide multiple ways for learners todemonstrate their achievements.Assessment andEvaluationThe terms assessment and evaluation are often used interchangeably,but they refer to quite different processes. Science curriculumdocuments developed in the Atlantic region use these terms for theprocesses described below.Assessment is the systematic process of gathering information onstudent learning.Evaluation is the process of analyzing, reflecting upon, andsummarizing assessment information, and making judgments ordecisions based upon the information gathered.The assessment process provides the data and the evaluation processbrings meaning to the data. Together, these processes improveteaching and learning. If we are to encourage enjoyment in learningfor students, now and throughout their lives, we must develop12 Chemistry 111 – 112 Curriculum

Part 1 The Teaching Frameworkstrategies to involve students in assessment and evaluation at alllevels. When students are aware of the outcomes for which they areresponsible, and the criteria by which their work will be assessed orevaluated, they can make informed decisions about the most effectiveways to demonstrate their learning.Regional curriculum in science suggests experiences that supportlearning within STSE, skills, knowledge and attitudes. It also reflectsthe three major processes of science learning: inquiry, problem solvingand decision making. When assessing student progress it is helpful toknow some activities/skills/actions that are associated with eachprocess of science learning. Examples of these are illustrated in thefollowing lists. Student learning may be described in terms of ability toperform these tasks.Inquiry Problem Solving Decision Making 13 Chemistry 111 – 112 Curriculumdefine questions related to a topicrefine descriptors/factors that focus practical and theoreticalresearchselect an appropriate way to find informationmake direct observationsperform experiments, record and interpret data, and drawconclusionsdesign an experiment which tests relationships and variableswrite lab reports that meet a variety of needs (limit theproduction of “formal” reports) and place emphasis onrecorded datarecognize that both quality of both the process and theproduct are importantclearly define a problemproduce a range of potential solutions for the problemappreciate that several solutions should be consideredplan and design a product or device intended to solve aproblemconstruct a variety of acceptable prototypes, pilot test,evaluate and refine to meet a needpresent the refined process/product/device and support whyit is “preferred”recognize that both quality of both the process and theproduct are importantgather information from a variety of sourcesevaluate the validity of the information sourceevaluate which information is relevantidentify the different perspectives that influence a decisionpresent information in a balanced manneruse information to support a given perspectiverecommend a decision and provide supporting evidencecommunicate a decision and provide a “best” solution

Part 1 The Teaching FrameworkOutcomesOutcomes FrameworkThe science curriculum is based on an outcomes framework thatincludes statements of essential graduation learnings, generalcurriculum outcomes, key-stage curriculum outcomes, and specificcurriculum outcomes. The general, key-stage, and specific curriculumoutcomes reflect the pan-Canadian Common Framework of ScienceLearning Outcomes K to 12. The conceptual map shown in Figure 1provides the blueprint of the outcomes framework.FIGURE 1Essential GraduationLearningsA Vision for ScientificLiteracy in Atlantic CanadaFour ciation of scienceNature of science andtechnologyInitiating and planningRelationship betweenscience and technologyAnalyzing and interpretingSocial and environmentalcontexts of science andtechnologyKNOWLEDGEPerforming and recordingCommunication and teamworkLife sciencePhysical scienceInterest in scienceScience inquiryCollaborationEarth and space scienceStewardshipSafetyKey-stage Curriculum OutcomesSpecific Curriculum OutcomesThis curriculum guide outlines grade level specific curriculum outcomes, and provides suggestions forlearning, teaching, assessment and resources to support students‟ achievement of these outcomes.Teachers should consult the Foundation for the Atlantic Canada Science Curriculum for descriptions ofthe essential graduation learnings, vision for scientific literacy, general curriculum outcomes, and keystage curriculum outcomes.14 Chemistry 111 – 112 Curriculum

Part 1 The Teaching FrameworkCurriculum GuideOrganizationSpecific curriculum outcome statements describe what students shouldknow and be able to do at each grade level. They are intended to serve asthe focus for the design of learning experiences and assessment tasks.Specific curriculum outcomes represent a reasonable framework forassisting students to achieve the key-stage, the general curriculumoutcomes, and ultimately the essential graduation learnings.Specific curriculum outcomes are organized in two to four units for eachgrade level. Each unit is organized by topic. Suggestions for learning,teaching, assessment, and resources are provided to support studentachievement of the outcomes.The order in which the units of a grade appear in the guide is meant tosuggest a sequence. In some cases the rationale for the recommendedsequence is related to the conceptual flow across the year. That is, oneunit may introduce a concept which is then extended in a subsequent unit.Likewise, it is possible that one unit focuses on a skill or context which willthen be built upon later in the year.It is also possible that units or certain aspects of units can be combined orintegrated. This is one way of assisting students as they attempt to makeconnections across topics in science or between science and the real world.Extended time frames may be needed to collect data over time. Thesecases may warrant starting the activity prior to the unit in which it will beused. In all cases logical situations and contexts should be taken intoconsideration when these types of decisions are made.The intent is to provide opportunities for students to deal with scienceconcepts and scientific issues in personally meaningful, and socially andculturally, relevant contexts.Unit OrganizationAll units comprise a two-page layout of four columns as illustrated in Figure2. Each unit is comprised of outcomes grouped by a topic which isindicated at the top of the left page.Column One:Essential LearningOutcomesThe first column lists a group of NB prescribed outcomes thatrelate to the pan-Canadian Specific Curriculum Outcomes listed atthe beginning of each unit. These are based on the pan-CanadianCommon Framework of Science Learning Outcomes K to 12. Thiscolumn also includes appropriate extensions for those studentsenrolled in Chemistry 111 or Chemistry 121. The statementsinvolve the Science-Technology-Society-Environment (STSE), skills,and knowledge outcomes indicated by the outcome number(s) thatappears in brackets after the outcome statement.Curriculum outcomes for each unit have been grouped by topic.Other groupings of outcomes are possible and in some cases maybe necessary in order to take advantage of local situations. Thegrouping of outcomes provides a suggested teaching sequence.Teachers may prefer to plan their own teaching sequence to meetthe learning needs of their students.15 Chemistry 111 – 112 Curriculum

Part 1 The Teaching FrameworkColumn Two:ElaborationsThe second column includes Elaborations of the outcomes, as wellas background information These Elaborations explain further thedepth of understanding that students should acquire. Also includedin this column are Teaching Suggestions, and Optional extensionsof the topic. The suggestions in this column are intended to providea holistic approach to instruction. In some cases, the suggestions inthis column address a single outcome; in other cases, they addressa group of outcomes.Column Three:Tasks for Instruction and/orAssessmentThe third column provides suggestions for ways that students‟achievement of the outcomes could be taught and assessed. Thesesuggestions reflect a variety of assessment techniques whichinclude, but are not limited to, informal/formal observation,performance, journals, interview, paper and pencil, presentations,and portfolio. Some assessment tasks may be used to assessstudent learning in relation to a single outcome, others to assessstudent learning in relation to several outcomes. The assessmentitem identifies the outcome(s) addressed by the outcome number inbrackets after the item.Column Four:NotesThis column will refer teachers to the supporting text and ancillaryresources.

Part 1 The Teaching FrameworkUnit OverviewAt the beginning of each unit, there is a two-page synopsis. On the firstpage, introductory paragraphs give a unit overview. These are followedby a section that specifies the focus (inquiry, problem solving, and/ordecision making) and possible contexts for the unit. Finally, acurriculum links paragraph specifies how this unit relates to scienceconcepts and skills that will be addressed at later grades so teacherswill understand how the unit fits with the students‟ progress through thecomplete science program.The second page of the two-page overview provides a table of theoutcomes from the Common Framework of Science LearningOutcomes K to 12 that will be addressed in the unit. The numberingsystem used is the one followed in the pan-Canadian document:100s - Science-Technology-Society-Environment (STSE) outcomes200s - Skills outcomes300s - Knowledge outcomes400s- Attitude outcomes (see pages 10-18)These code numbers appear in brackets after each specific curriculumoutcome (SCO).FIGURE 3Unit OverviewUnit Title: Unit OverviewIntroductionSynopsis of the unitFocus and ContextsFocus: Inquiry, DecisionMaking, or ProblemSolving.

Part 1 The Teaching FrameworkAttitude OutcomesIt is expected that certain attitudes will be fostered and developed throughoutthe entire science program, entry to grade 12. The STSE, skills andknowledge outcomes contribute to the development of attitudes, andopportunities for fostering these attitudes are highlighted in the Suggestionsfor Learning and Teaching section of each unit.Attitudes refer to generalized aspects of behaviour that are modeled forstudents by example and reinforced by selective approval. Attitudes are notacquired in the same was as skills and knowledge. The development ofpositive attitudes plays an important role in students‟ growth by interactingwith their intellectual development and by creating a readiness for responsibleapplication of what they learn.Since attitudes are not acquired in the same way as skills and knowledge,outcomes statements for attitudes are written for the end of grades 3, 6, 9 and12. These outcomes statements are meant to guide teachers in creating alearning environment that fosters positive attitudes.The following pages present the attitude outcomes from the pan-CanadianCommon Framework of Science Learning Outcomes K to 12.19 Chemistry 111 – 112 Curriculum
