Knowledge and Employability courses provide students who meet the criteria with opportunities to experience success and become well prepared for employment, further studies, citizenship and lifelong learning.

Vision

Through Knowledge and Employability courses, students become active and responsible citizens, achieve their educational and career goals, improve quality of life for themselves and their families and positively impact their communities.

Philosophy & Rationale

The development of the Knowledge and Employability courses was based on input received from consultations with education stakeholders throughout the province. The distinctive sequence of courses was designed to meet the educational needs of students who learn best:

  • when focusing on the development and application of reading, writing and mathematical literacy1, and on essential employability skills
  • through experiential learning activities
  • when meaningful connections are made between schooling and personal experiences.

1Mathematical literacy: Selecting and applying appropriate mathematical operations, problem-solving strategies, tools and technology, and communicating using mathematical vocabulary in home, workplace and community experiences.

Knowledge and Employability courses assist students in:

  • transitioning from school to the workplace and community
  • preparing for responsible citizenship
  • gaining recognition, respect and value from employers and further education providers.

Knowledge and Employability courses promote student skills, abilities and work ethics, including:

  • academic and occupational skills of a standard determined by the workplace to be necessary for success
  • practical applications through on- and off-campus experiences and/or community partnerships
  • career development skills to explore careers, develop a career-focused portfolio and assess career skills
  • interpersonal skills to ensure respect, support and cooperation with others.
Aboriginal Perspectives and Experiences 

For historical, constitutional and social reasons, an understanding of First Nations, Métis and Inuit (FNMI) experiences and perspectives, and recognition that First Nations, Métis and Inuit students have particular needs and requirements, is necessary to enable all students to be respectful and responsible citizens.

Knowledge and Employability courses serve to facilitate positive experiences that will help Aboriginal students better see themselves in the curriculum and assist non-Aboriginal students to develop a better understanding of Alberta’s First Nations, Métis and Inuit peoples.

Goals of Knowledge and Employability Courses

Knowledge and Employability courses provide students with practical and applied opportunities to develop competencies necessary to meet or exceed the following goals. Knowledge and Employability courses prepare students to:

  • earn a senior high school credential
  • enter the workplace upon leaving school with employability and occupational skills that meet industry standards
  • make successful transitions to other courses or to further education and training
  • become responsible and contributing members of society.
Cross-curricular Community and Workplace Connections

Programs of study and resources for Knowledge and Employability courses are distinctive, in part, because they promote cross-curricular, community and workplace connections.

Cross-curricular Connections

Knowledge and Employability courses promote the integration of subjects to emphasize their interrelationships and connections to other school subjects. The philosophy of Knowledge and Employability courses is that students learn best when they can clearly recognize, in their course work, connections, applications and relevance to a variety of everyday experiences. Organizing for instruction may include thematic units, subject integration within units and/or projects in other subjects.

Community and Workplace Connections

Knowledge and Employability courses provide students with practical and applied opportunities to develop basic reading, writing and mathematical literacy. Community and workplace connections ensure learning within applied contexts, connecting the school with environments beyond school, and may include tours to local businesses and industries, mentorships, job shadowing and work experience.

Knowledge and Employability courses promote the development of career portfolios that help students connect their school experience to the world beyond school. Each portfolio will include exemplars of the student’s on- and off-campus experiences and can be used when the student is seeking employment or further education/training opportunities. Items appropriate for inclusion in career portfolios include résumés, samples of written work, awards and/or their representations, teacher and self-evaluation checklists, workplace assessment tools and employer letters of recommendation.

Safety

Safety is emphasized and relevant information is incorporated throughout Knowledge and Employability courses, including basic safety rules and guidelines and information regarding the safe use of tools, equipment and materials in school, home, community and workplace settings.

Technology

The Information and Communication Technology (ICT) curriculum is infused throughout the Knowledge and Employability courses, including the use of computers and other technology, to support the instruction of technology within an applied context.

Essential Universal Skills and Strategies

Knowledge and Employability courses emphasize the universal skills and strategies that are essential to all students, including the following.

  • Interpersonal skills promote teamwork and respect for, support of and cooperation with others.
  • Critical thinking promotes the analysis and appropriate applications of information.
  • Creative thinking promotes the identification of unique connections among ideas and insightful approaches to questions and issues.
  • Decision-making processes promote the making of timely and appropriate decisions.
  • Problem-solving processes promote the ability to identify or pose problems and apply learning to consider the causes and dimensions of, and the solutions to, problems.
  • Metacognition2 enables students to become more aware of, and have greater control over, their own thinking and learning processes.

2Metacognition: Learning-to-learn strategies; awareness of processes and strategies one uses when learning.

Relationship to Other Courses

Each Knowledge and Employability course is consistent with the rationale, philosophy, program foundations and organization of other secondary courses. This consistency enables students, as appropriate, to progress through the Knowledge and Employability course sequence and/or to other secondary courses.

Enrollment in Knowledge and Employability Courses

Students may take one or more courses in the sequence at any time during grades 8 through 12. Students may be enrolled in only Knowledge and Employability courses or in a combination of Knowledge and Employability and other secondary courses.

Information regarding the identification of students for enrollment in one or more courses can be accessed in the Knowledge and Employability Courses Handbook, Grades 8–12.

Rationale & Philosophy of Knowledge & Employability Science

Knowledge and Employability science courses focus on developing and applying essential science skills, knowledge and attitudes needed for everyday living at home, in the workplace and in the community. Science competencies are developed through the investigation of science-related problems, questions and issues and through everyday applications that help students understand and appreciate the role of science in society.

Knowledge and Employability science courses emphasize career and life skills, teamwork, communication skills and thinking processes. Each grade level is developed within a scientific-inquiry framework, emphasizing problem-solving and decision-making skills based on students’ abilities and everyday applications.

Diverse learning experiences within science courses provide students with opportunities to explore, examine and appreciate the interrelationships among science, technology, society and the environment. These learning experiences also develop understandings that will affect the lives of students at home, in the workplace and in the community.

Science Foundations

Knowledge and Employability science courses promote the development of the four foundations of science.

Foundation 1: Science, Technology and Society (STS)

Students will explore their everyday home, workplace and community environments, gather information, develop ideas and use technology and other tools to make decisions about their personal lives. Students will recognize the influence of science on decision making by individuals, communities and society.

Foundation 2: Knowledge

Students will investigate theories, models, concepts, processes and principles in life science, physical science and Earth and space science, with an emphasis on application to everyday living.

Foundation 3: Skills

Students will develop skills in scientific communication and teamwork, initiating and planning, performing and recording, and analyzing and interpreting to answer questions, solve problems and make decisions in their everyday lives.

Foundation 4: Attitudes

Knowledge and Employability science courses emphasize the development of positive attitudes and behaviours related to collaboration, mutual respect, safety and stewardship in everyday living.

Goals

The principal goal of the Knowledge and Employability science courses is to develop science competencies to assist students to become contributing members of society and independent and lifelong learners. These competencies include:

  • communication and teamwork skills for use in collaborative group work
  • attitudes that enable the responsible use of knowledge and skills
  • the selection and application of appropriate science skills, tools and strategies to understand and interpret the world
  • the exploration of interests and ideas, using appropriate problem-solving and decision-making strategies
  • the application of science understandings, skills and attitudes to everyday life/work situations.
Units of Study

When science components are organized into appropriate contexts, students can use their knowledge to solve problems and make decisions about science in relation to their everyday experiences.

The units of study provide the contexts within which the skills, attitudes, knowledge and science, technology and society (STS) outcomes are developed, based on students’ abilities and everyday living at home, in the workplace and in the community.

Each unit of study has focusing questions to provide direction for inquiry. Specific outcomes include key concepts.

Examples

Many of the outcomes are supported by examples. The examples do not form part of the required program but are provided as an illustration of how the outcomes might be developed. Illustrative examples are written in italics and are separated from the outcomes by being placed in parentheses.

Unit B: Cells & Systems

Unit B: Cells and Systems (Nature of Science Emphasis)

Overview

Living things take a variety of forms, as reflected in their structures, internal processes and ways of responding to their environments. Finding patterns within this diversity has been a major challenge in the biological sciences and has led to the development of ideas, e.g., systems, cells, structures and functions, from the study of all living things. Using these ideas, students learn to interpret life at a variety of levels, from individual cells to complex organisms. To develop their understanding, students investigate other ways that components of a living system work together and, through these studies, learn that healthy organisms - including healthy humans - function as balanced systems within a life-supporting environment.

  • state a prediction or hypothesis based on background information or an observed pattern of events (e.g., predict the next appearance of a comet, based on past observations).

Performing and Recording

Students will:

apply science-related performing and recording skills to conduct investigations into the relationships among observations and gather and record data at home, in the workplace and in the community

  • research information relevant to a given problem
  • select information from various print and electronic sources
  • organize data, using a format that is appropriate to a given task or experiment (e.g., maintain a log of observed changes in the night sky).

Analyzing and Interpreting

Students will:

apply science-related analyzing and interpreting skills to examine data and develop and assess possible explanations at home, in the workplace and in the community

  • identify the strengths and weaknesses of different methods of collecting and displaying data (e.g., compare Earth-based observations with those made from spacecraft)
  • identify new questions and problems that arise from what was learned (e.g., identify questions to guide further investigations, such as, "What limits travelling distance and duration of space exploration?").

Communication and Teamwork

Students will:

apply science-related communication and teamwork skills to work collaboratively on problems and use appropriate language and formats to communicate ideas, procedures and results at home, in the workplace and in the community

  • receive, understand and act on the ideas of others
  • work cooperatively with other team members to develop and conduct a plan and troubleshoot problems as they arise.
Attitude Outcomes

Students will be encouraged to develop and display an interest in science and scientific inquiry and mutual respect, collaboration, stewardship and safety at home, in the workplace and in community situations.

Interest in Science

Students will be encouraged to:

  • show interest in science-related questions and issues and pursue personal interests and career possibilities within science-related fields (e.g., express interest in and describe media programs on space science and technology)

Mutual Respect

Students will be encouraged to:

  • understand that scientific understanding evolves from the interaction of ideas involving people with different views and backgrounds (e.g., show an interest in the contributions men and women from many cultural backgrounds have made to the development of modern science and technology)

Scientific Inquiry

Students will be encouraged to:

  • value and use scientific methods to carefully gather evidence when investigating problems and issues (e.g., consider observations and ideas from a number of sources before drawing a conclusion)

Collaboration

Students will be encouraged to:

  • work collaboratively when conducting investigations and when generating and evaluating ideas (e.g., share ideas and observations with other members of the group)

Stewardship

Students will be encouraged to:

  • demonstrate sensitivity when pursuing a balance between the needs of humans and the requirements for a sustainable environment (e.g., consider immediate and long-term consequences of personal and group actions)
  • recognize that the traditional Aboriginal lifestyle supports a unique relationship with the environment

Safety

Students will be encouraged to:

  • demonstrate concern for safety when planning, conducting and reviewing activities (e.g., select safe methods and tools for collecting evidence).
