CONSIDERATIONS FOR PROGRAM PLANNING
Instructional Approaches
Teachers in the school are expected to:
clarify the purpose for learning
help students activate prior knowledge
differentiate instruction for individual students and small groups according to need
explicitly teach and model learning strategies
encourage students to talk through their thinking and learning processes
provide many opportunities for students to practise and apply their developing knowledge and skills
apply effective teaching approaches involve students in the use of higher-level thinking skill
encourage students to look beyond the literal meaning of texts.
Teachers use a variety of instructional and learning strategies best suited to the particular type of learning. Students have opportunities to learn in a variety of ways:
individually
cooperatively
independently with teacher direction
through investigation involving hands-on experience
through examples followed by practice
by using concrete learning tools - manipulatives - in mathematics such as connecting cubes, measurement tools, algebra tiles, and number cubes
by encouraging students to gain experience with varied and interesting applications of the new knowledge. Rich contexts for learning open the door for students to see the “big ideas” of mathematics that will enable and encourage them to reason mathematically throughout their lives.
Promoting Positive Attitudes Towards Learning Mathematics
Teachers must be careful to build a positive environment in which students may study mathematics; students that enjoy the courses are more likely to do well and enrol in more advanced mathematics courses.
Teachers can set students up for developing positive attitudes by providing opportunities for them to:
be engaged in making mathematical conjectures
experience breakthroughs as they solve problems
see connections between important ideas
see their teacher’s enthusiasm about teaching mathematics
Teachers must be mindful students developing negative attitudes whether through a feeling of inadequacy or anxiety from not solving problems quickly, easily, or in the correct manner. Students should be able to recognize that:
There are many correct ways to come to a solution
Problem solving requires time and effort to learn, and requires perseverance
With this perseverance comes the ability to move past barriers and overcome the frustration of getting stuck
Teachers can encourage students to keep trying a problem when they are stuck and guide them through routes of thought to arrive at a solution, as well as encourage students to develop this perseverance as being challenged and overcoming barriers are cornerstones of education.
Teachers must be mindful of their students’ confidence in their skills in order for them to continue seeing success and understanding in their studies.
Program Considerations for Students with Special Education Needs
Teachers must incorporate appropriate strategies for instruction and assessment to facilitate the success of students with special educational needs in their classrooms. These strategies stem from the beliefs as laid out in Special Education Transformation: The report of the Co-Chairs with the Recommendations of the Working Table on Special Education, 2006:
All students can succeed
Universal design and differentiated instruction are effective and interconnected means of meeting the learning or productivity needs of any group of students
Successful instructional practices are founded on evidence-based research, tempered by experience
Classroom teachers are key educators for a students’ literacy and numeracy development.
Each student has his or her own unique patterns of learning.
Classroom teachers need the support of the larger community to create a learning environment that supports students with special education needs.
Fairness is not sameness.
Teachers must plan their program that recognize the diversity of students’ learning styles, needs, and responses, so students can have performance tasks that respect their abilities so they can derive the greatest possible benefit from the teaching and learning process.
Teachers must be mindful of three types of accommodations for students at Brain Power:
Instructional Accommodations: changes in teaching strategies, including styles of presentation,methods of organization, or use of technology and multimedia
Environmental Accommodations: changes that the student may require in the classroom and/or school environment, such as preferential seating or special lighting.
Assessment accommodations: changes in assessment procedures that enable the student to demonstrate his or her learning, such as allowing additional time to complete tests or assignments, or permitting oral responses to test questions
No modifications to course expectations are made at Brain Power.
Program Considerations for English Language Learners
Teachers must incorporate appropriate strategies for instruction and assessment to facilitate the success of the English language learners in their classrooms. These strategies include:
modification of some or all of the subject expectations depending on the level of English proficiency
use of a variety of instructional strategies (e.g., extensive use of visual cues, graphic organizers, scaffolding; previewing of textbooks; pre-teaching of key vocabulary; peer tutoring; strategic use of students’ first languages)
use of a variety of learning resources (e.g., visual material, simplified text, bilingual dictionaries, and materials that reflect cultural diversity)
use of assessment accommodations (e.g., granting of extra time; use of oral interviews, demonstrations or visual representations, or tasks requiring completion of graphic organizers and cloze sentences instead of essay questions and other assessment tasks that depend heavily on proficiency in English).
Antidiscrimination Education
Learning resources reflect students’ interests, backgrounds, cultures, and experiences. Learning materials should:
enable students to become more sensitive to the diverse cultures and perceptions of others, including Aboriginal peoples
discuss aspects of the history of mathematics to make students aware of the various cultural groups that have contributed to the evolution of mathematics over the centuries
illustrate to students that everyday people use mathematics in their everyday lives, both at work and at home
connect mathematics to real world situations and human affairs such as health, science, environmental studies, trend analysis, and politics.
Literacy and Inquiry/Research Skills
The school emphasizes the importance of the following:
using clear, concise communication in the classroom involving the use of diagrams, charts, tables, and graphs
emphasizing students’ ability to interpret and use graphic texts.
acquiring the skills to locate relevant information from a variety of sources, such as books, newspapers, dictionaries, encyclopaedias, interviews, videos, and the Internet.
learning that all sources of information have a particular point of view
learning that the recipient of the information has a responsibility to evaluate it, determine its validity and relevance, and use it in appropriate ways.
Role of Technology
Information and communications technologies (ICT) tools used in many ways:
Students use multimedia resources, databases, Internet websites, digital cameras, and word-processing programs.
Students use databases, spreadsheets, dynamic geometry and statistical software, graphing software, computer algebra systems, and so on in order to quickly navigate through complex problems, to see the effect of dynamic data on their values and trends, and to see a graphical representation of data.
They use technology to collect, organize, and sort the data they gather and to write, edit, and present reports on their findings.
Students are encouraged to use ICT to support and communicate their learning. For example, students working individually or in
Students use digital cameras and projectors to design and present the results of their research to their classmates.
The school plans to use ICT to connect students to other schools and to bring the global community into the classroom.
Students are made aware of issues of Internet privacy, safety, and responsible use, as well as of the potential for abuse of this technology, particularly when it is used to promote hatred.
Career Education
Students are given opportunities to develop career-related skills by:
applying their skills to work-related situations
exploring educational and career options
developing research skills
developing key essential skills such as reading text, writing, computer use, measurement and calculation, and problem solving
practising expository writing
learning strategies for understanding informational reading material
making oral presentations
working in small groups with classmates to help students express themselves confidently and work cooperatively with others.
Financial Literacy
The school is emphasizing the importance of ensuring that Ontario students have the opportunity to improve their financial literacy. Financial literacy is defined as “having the knowledge and skills needed to make responsible economic and financial decisions with competence and confidence”. The goal is to help students acquire the knowledge and skills that will enable them to understand and respond to complex issues regarding their own personal finances and the finances of their families, as well as to develop an understanding of local and global effects of world economic forces and the social, environmental, and ethical implications of their own choices as consumers. Thus, an attempt will be made to integrate Financial Literacy in all the school’s courses.
Academic Honesty
Students who present the work of others as their own are guilty of plagiarism and will receive a mark of zero for the work and will have the details of the plagiarism noted in their school records. Students who are guilty of cheating on tests or examinations will receive a mark of zero on the test or examination and have the details of the cheating noted in their school records.
Late Assignments
Students are responsible for providing evidence of their achievement of the overall expectations within the time frame specified by the teacher, and in a form approved by the teacher. There are consequences for not completing assignments for evaluation or for submitting those assignments late.
