CalGeo: Teaching Calculus using dynamic geometric tools Outcome 1.1.1 : “Report on existing curricula. Questionnaire, Greece” COMENIUS PROGRAM CalGeo CALCULUS CURRICULUM QUESTIONNAIRE ********************************** Greece i OCTOBER 2004 ▄ National Curriculum _____________________________________________________________________ IMPORTANT: Throughout this questionnaire, the term “mathematics national curriculum” is intended to include any centrally-supported curriculum. This curriculum may not be articulated in a formal document, or different aspects of the curriculum may appear in different documents. _____________________________________________________________________ 1. Does your country have a mathematics national curriculum that includes calculus at grades 10, 11 and 12? Fill in one circle only_______________________________________ Yes No O Note: If No, please complete the remainder of the questionnaire based on your best-informed judgment of the intended mathematics curriculum for the majority of grades 10, 11 and 12 students in your country. If it is impossible to answer a particular question, just make a note and move to the next question. 2. In what year was the current intended calculus curriculum for grades 10, 11 and 12 introduced? The reform of national curriculum concerning mathematics in grades 10 to 12 started at 1989. The application of this new curriculum started gradually during the period 1990-1993 and it is still active, with some revisions, until nowadays. 3. What are the main differences of the current calculus curriculum from the previous one? (if any) According the previous curriculum: o The Sequences of Real numbers, their limits and properties were taught. o The exponential function was defined as an application of sequences of real numbers. o Emphasis to epsilonic definition of limit and continuity. o There were definitions and theorems about bounded functions. o Much more proofs of theorems. o No indefinite integration was included o Volume of a solid of revolution was included. ii 4. Is the intended calculus curriculum that includes grades 10, 11 and 12 currently being revised? Fill in one circle only _______________________________________ Yes No O 5. Which best describes how the calculus national curriculum at grades 10, 11 and 12 addresses the issue of students that take mathematics as a selective course? Fill in one circle for each column Grade 10 The same curriculum is prescribed for all students (i.e. There is not an option for basic or advanced mathematics) Different curriculum is prescribed for the students that take mathematics as a selective course Grade 11 Grade 12 O O O 6. Does the national curriculum contain statements/policies about the use of graphic calculators in grades 10, 11 and 12 calculus? Fill in one circle only _______________________________________ Yes No O If YES, what are the statement/policies? ____________________________________________________________ ____________________________________________________________ 7. Does the national curriculum contain statements/policies about the use of computers/computer software in grades 10, 11 and 12 calculus?

As part of in-service education____________________ O If you answered YES to either (a) or (b), describe the nature of the preparation. ____________________________________________________________ ____________________________________________________________ iv 11. According to the national mathematics curriculum, at which grades the following calculus topics are taught? If at a particular grade there is a different curriculum for students that take mathematics as a selective course, please complete the extra columns. Please write other topics or subjects if necessary. Please indicate with an asterisk (in the topic column) if a topic is not actually taught (or taught in a different way) although it is included in the curriculum of a specific grade. Explain in the “Notes” space if this is the case. Curriculum for all students Topic Curriculum for students having mathematics as a selective course Grade Primarily Grade Primarily taught taught 10 11 12 10 11 12 A. Real Numbers* a) b) c) d) Natural numbers - Induction Rational numbers (basic properties) Irrational numbers Other topics or theorems: (Please X X X X specify) …………………………….. …………………………….. Notes:* There are introductory lessons about set of numbers (Natural, Rational, Irrational, Real numbers) at grades less than 10. In these lessons is highlighted the differences between the different meanings and symbolizations of these numbers and there is no emphasis in the characteristic properties of each set. In Grade 10 there is a general representation of set of real numbers and its properties concerning operations and ordering. In addition, the real number line is used as an external representation for real numbers. B.
