(a) General requirements. This course is recommended
for students in Grades 11 and 12. Prerequisite: Algebra II. This course
satisfies a high school mathematics graduation requirement. Students
shall be awarded one credit for successful completion of this course.
(b) Introduction.
(1) Career and technical education instruction provides
content aligned with challenging academic standards and relevant technical
knowledge and skills for students to further their education and succeed
in current or emerging professions.
(2) The Science, Technology, Engineering, and Mathematics
(STEM) Career Cluster focuses on planning, managing, and providing
scientific research and professional and technical services, including
laboratory and testing services, and research and development services.
(3) Engineering Mathematics is a course where students
solve and model design problems. Students will use a variety of mathematical
methods and models to represent and analyze problems that represent
a range of real-world engineering applications such as robotics, data
acquisition, spatial applications, electrical measurement, manufacturing
processes, materials engineering, mechanical drives, pneumatics, process
control systems, quality control, and computer programming.
(4) The mathematical process standards describe ways
in which students are expected to engage in the content. The placement
of the process standards at the beginning of the knowledge and skills
listed for each grade and course is intentional. The process standards
weave the other knowledge and skills together so that students may
be successful problem solvers and use mathematics efficiently and
effectively in daily life. The process standards are integrated at
every grade level and course. When possible, students will apply mathematics
to problems arising in everyday life, society, and the workplace.
Students will use a problem-solving model that incorporates analyzing
given information, formulating a plan or strategy, determining a solution,
justifying the solution, and evaluating the problem-solving process
and the reasonableness of the solution. Students will select appropriate
tools such as real objects, manipulatives, paper and pencil, and technology
and techniques such as mental math, estimation, and number sense to
solve problems. Students will effectively communicate mathematical
ideas, reasoning, and their implications using multiple representations
such as symbols, diagrams, graphs, and language. Students will use
mathematical relationships to generate solutions and make connections
and predictions. Students will analyze mathematical relationships
to connect and communicate mathematical ideas. Students will display,
explain, or justify mathematical ideas and arguments using precise
mathematical language in written or oral communication.
(5) Students are encouraged to participate in extended
learning experiences such as career and technical student organizations
and other leadership or extracurricular organizations.
(6) Statements that contain the word "including" reference
content that must be mastered, while those containing the phrase "such
as" are intended as possible illustrative examples.
