__Background and Rationale__

Contemporary mathematics pedagogy measures an educative growth of a student not in terms of the production of correct answers but in terms of the quality and diversity of thinking. Nowadays, a competence in elementary mathematics teaching means much more than the ability to get a right answer to a standard, procedure-bounded problem. The competence includes an in-depth understanding of the concepts behind procedures being taught and awareness of various tools conducive to mediate conceptual development. This course will reflect change and growth in mathematics education set by the Common Core State Standards Initiative adopted by New York State in 2010 toward the goal of having greater focus and coherence in teaching school mathematics. The course will attempt to increase the confidence level of a future teacher in creating learning situations at the elementary level in which simply stated questions about familiar concepts can generate a considerable amount of inquiry.

To this end, mathematics currently involved in K-6 program as recommended by the New York State Education Department as well as by the Ontario Ministry of Education will be highlighted as a dynamic discipline, built on progressively connected ideas and mutually related concepts. Students will be introduced to current issues and trends in mathematics education such as the use of concrete embodiments (physical manipulatives) and computing technology (including electronic manipulatives), revision of curriculum and professional standards, assessment of authentic performance, and social constructivism.

__SUNY Potsdam Education Unit Conceptual Framework__

__A Tradition of Excellence: Preparing Creative and Reflective
Practitioners__

GRED 565 course supports the SUNY Potsdam Education Conceptual Framework in several ways. First, through experiences provided in this course students will continue to develop as "well educated citizens" by modeling the skills, attitudes, and values of inquiry relevant for mathematics content and by appropriately using technology such as the Internet, word processing, spreadsheets, and other electronic information technologies. They will continue to develop as 'reflective practitioners" by modeling inquiry, practice, and reflection in their field experiences and journals. They will effectively use research-based models of curriculum, instruction, and assessment as they plan for instruction, design, and teach lessons meeting the diverse learning needs of students, promoting reflective inquiry, critical thinking, and problem solving, incorporating appropriate technology. They will identify national and state learning standards that are related to their lessons. They will develop as "principled educators" by demonstrating

- appropriate integrity and competence for beginning level pre-service teachers,
- professional behavior in their classes and in the field,
- ability to work with pre-K-6 students and teachers, and
- disposition to see the elementary classroom as a site for inquiry.

__Course Content and Pedagogy__

The course content will revolve around the following eight Standards for Mathematical Practice set by the Common Core: (1) Make sense of problems and persevere in solving them; (2) Reason abstractly and quantitatively; (3) Construct valuable arguments and critique the reasoning of others; (4) Model with mathematics; (5) Use appropriate tools strategically; (6) Attend to precision; (7) Look and make use of structure; (8) Look and express regularity in repeated reasoning. The course pedagogy will be aligned with the following Instructional Shifts that are of critical importance for implementing the above eight standards for Mathematical Practice: Focus, Coherence, and Rigor. The demonstration of these shifts will be supported by a variety of mathematics education materials. Furthermore, in accord with the National Council of Teachers of Mathematics Professional Standards for Teaching Mathematics, the course pedagogy will focus on developing proficiency in:

- selecting mathematical tasks to engage children's interests and intellect;
- orchestrating classroom discourse in ways that promote conceptual growth;
- seeking, and helping children seek, connections to previous and developing knowledge;
- using, and helping children use, technology to pursue mathematical explorations.

To this end, student-centered discussions of selected mathematics education research publications and Common Core State Standards for Mathematics will be a part of the course activities. Students will be expected to read these publications by using the campus (Crumb) library and the Internet resources. Fostering the ability to use such resources is one of educational objectives of this (graduate level) course.

__Evaluation Criteria__

- Professionalism

Students are expected to attend, be prepared for, and participate professionally in each class. This includes the ability to support classroom activities by participating in discussions of homework and readings. Professionalism also includes the ability to keep notes of all class discussions and home assignments, using library and the Internet resources to access information, using e-mail and word processing programs as educational tools.

Special note regarding the weekend offering of the course. Because of intensive nature of studies in such a format, students who miss any weekend (or the time-equivalent combination of classes) will be asked to drop the course and take it at a different time.Those students who miss one full day (either Friday or Saturday) due to a family emergency (which must be documented) may be allowed to make up work in some form (TBA) at the discretion of instructor.

- Assignments

Students are expected to read the text book, course materials, and selected mathematics education publications as assigned by the instructor. Throughout the semester, please plan to watch carefully for assignments given. Some assignments may involve the use of a computer and students must plan for time to work in a Mac computer lab on such assignments. Students are expected to have (or acquire) a minimum knowledge of Microsoft Word, Microsoft Excel, and Dynamic Geometry programs. As stated in the New York State Education Department Core Curriculum for Mathematics, "software that allows students … to explore, conjecture and investigate mathematics, provides unique opportunities for students learning mathematics. Teachers should take full advantage of this resource, if available" (see the web site of NY State Education Department at http://www.nysed.gov/rscs/resguide/Mathcc1.pdf, Resource Guides, Mathematics, Elementary Grades, p. 12). Note that these high expectations are set for students (and their teachers alike) as early as in elementary grades.

- Presentations

The course activities will include (depending on a final enrollment) up to eight student-centered discussions of research publications relevant to elementary mathematics curriculum. (These publications have been put on GRED 565 reserve at the Crumb library). To this end, teams of at most 4 students in each team will be created. Each team will be responsible for doing one such discussion. More specifically, this will include the following collaborative activities:

- the preparation of not fewer than a 600-word summary of a publication (a write-up) which must be submitted as an MS Word document to the instructor electronically in accord with the schedule published on-line;
- the preparation of not fewer than a 300-word reflection on the publication (a write-up) which must be submitted to the instructor in hard copy by the day of a discussion;
- conducting a 35-minute discussion of an assigned publication (longer presentations would not be appreciated).

Each such summary will be put on the course web site on a week preceding a discussion with understanding that the whole class can be prepared for discussion by reading this summary via the Internet. (In order to count the number of words in a typed document, one can use "Word Count" feature from Tools menu of MS Word program). One copy of each document is required for a team. In evaluating a presentation, the following rubric will be applied:

Group e-summary of not less than 600 words submitted on time - 20%

Individual reflection of not less than 300 words submitted on time - 20%

The use of a computer during the presentation - 20%

The use of manipultives during the presentation - 20%

The use of transparencies and/or handouts, auxiliary literature, conducting whole class discussion during the presentation - 20%

Submitted individual reflections will be available for a pick up (with my evaluation of the whole presentation) in the plastic box attached to the door of 210 Satterlee Hall on the day of presentation (unless an emergency occurs). Please pick up your graded reflections promptly.

- Topic exams

Two topic exams will be given during the semester. These topic exams (**to be arranged**) will be based on readings, homework, and activities presented in the class. A reading list will be given a week before a topic exam. There will be **no make-up topic exams given **unless** illness or family emergency occur** (these must be **documented)**.

- Final Project

A final exam for the course will be replaced by work on a final project. A final project may take different directions. One such direction is to develop a lesson based on one of the key idea/strands from mathematics core curriculum as recommended by New York State Department of Education/Ontario Ministry of Education (see mentioned above GRED 565 Course Materials) and/or Common Core State Standards for Mathematics. The second direction is to structure a project as a journal that reflects on one's experience in observing an elementary mathematics classroom in the field. Reflections should describe one's observations in terms of their connection to ideas studied in the course. Finally, the third direction is to reflect on a possible involvement in teaching mathematics during a field experience. Regardless of a direction chosen, an underlying philosophy of a final project should be structured by the following basic assumptions of contemporary classroom discourse:

- conceptual development (emphasis on conceptual understanding versus operational understanding),
- reflective inquiry (creating a learning environment in which students feel comfortable to ask "what if" and "why" questions and reflect on their work),
- search of connections between different concepts (e.g., addition and subtraction, multiplication and division, etc.), and
- the use of technology (e.g., physical manipulatives, computers, the Internet, computer-generated worksheets, overheads, and so on).

The length of a final project is expected to be three to five pages (not fewer than a 1000-word document typed on a computer). Team projects (not more than three students in a team) are welcome, but collaboration on a project is not required. On the cover sheet of the project please type your e-mail address (it should include e-mail addresses of all team members if it's a collaborative project).

If your final project is an observation journal, please follow guidelines provided in the "pink" document (Field Experience Guidelines). Of particular interest is any information related to students' asking questions during a lesson, the discussion of more than one way to solve a problem, the availability of manipulatives and computers in the elementary classroom and their use by a host teacher. If the use of these tools was never observed, please write about that including grade level(s) observed. Information submitted in your final project based on classroom observations will be considered strictly confidential.

If you are involved in student teaching during your practicum, please write in your final project about topic taught and instructional materials used; describe most interesting episodes from your teaching experience.

If your final project is a lesson plan, it should be relevant to the elementary classroom. Your lesson plan may be based on one of the Common Core State Standards for Mathematical Content or on one of the strands in the Ontario Mathematics Curriculum. In your lesson plan please address such issues as the use of manipulatives and information technology, conceptual development, the promotion of reflective inquiry and diversity of thinking among students.

- Components of a final grade

Home assignments 20%

The use of technology 10%

Topic exams 30%

Final Project 20%

3. Team projects (not more than three students in a team) are welcome, but collaboration on a project is not required.

4. If your project is an observation journal, please follow the guidelines provided in the "pink" document. Of particular interest is information related to students asking questions during a lesson, classroom discussion about more than one way to solve a problem, the availability of manipulatives and computers in the elementary classroom and their use by your host teacher. If you have never observed the use of these tools, please write about that. It should include grade level observed; if you observed multiple grade levels, please list all grades you were involved with.

5. If you were involved in student teaching during your 100-hour field experience (practicum), please write about what you have taught, what materials you’ve used, describe most interesting episodes from your teaching experience.

6. You may also present a lesson plan (supported by NY State or Ontario standards and core curriculum for mathematics – please see the course materials booklet) relevant to the elementary classroom. Your lesson may be based on one of the key ideas/strands from the core curriculum. In your lesson plan please describe how you plan to address such issues as the use of manipulatives and information technology, developing mathematical connections, promoting reflective inquiry and diversity of thinking among students.

7. As mentioned in the syllabus, regardless of the type of your final project, its underlying philosophy should be structured by the following basic assumptions of contemporary pedagogy: conceptual development (emphasis on conceptual understanding vs. operational understanding – teaching through problem solving in context rather than through worksheets), reflective inquiry (creating a learning environment in which students feel comfortable to ask "what if" and "why" questions and reflect on their work and that of their peers), making connections among different concepts (e.g., between counting and addition, between addition and subtraction, between addition and multiplication, between subtraction and division, between multiplication and division), and the use of technology (e.g., physical manipulatives, computers, the Internet, computer-generated worksheets, overheads, and so on).
