The key questions are: is it true that persons with Down’s syndrome can study mathematics only at a very elementary level? Might it be possible that their difficulties are mainly restricted to some fields, such as numeracy and mental computation, but do not encompass the entire domain of mathematics? Is the use of a calculator recommended? Is non-elementary mathematics accessible at most for the brightest students with Down’s syndrome? Our experience with about 30 students with Down’s syndrome, attending Italian mainstream secondary schools, is that these students can solve mathematical problems, using simple algebraic equations, though they may have very poor numeracy skills and need to use the calculator even with the simplest computations. Moreover, a familiarity with more advanced topics, as algebraic computation and analytic geometry, can help to raise their self-esteem and improve their numeracy too. Surprisingly, these students can learn and apply mathematical procedures in a variety of other different contexts. For instance, Francesca, an Italian student attending a secondary mainstream school, with a mild impairment in numeracy and relatively good linguistic skills, started with algebra and then learned to solve problems in the areas of nutritional science and of business administration. In the same way, Martina, a student in a mainstream secondary school with severe linguistic and numerical impairments, learned to work with Cartesian coordinates and formulas in analytic geometry. She began connecting points on a Cartesian plane, given their coordinates, and colouring in the shapes, such as flowers and animals, that they define. Applying the two points distance formula and verifying the result, she learned to measure the distance of two points with a ruler and to understand the concept of ‘millimetres’. The role of the inclusion in mainstream Italian schools of every disabled student, regardless the severity of the disability, has been crucial for these results. 相似文献

The paper reports on the introduction of the graphics calculator into three centralised examination systems, which were located
in Denmark, Victoria (Australia) and the International Baccalaureate. The introduction of the graphics calculator required
those responsible for writing examination questions to consider how to assess mathematical skills within this new environment.
This paper illustrates the types of mathematics skills that have been assessed within the graphics-calculator-assumed environment.
The analysis of the examination questions indicated that only two out of the six mathematics examinations considered demonstrated
any significant change in the types of skills assessed in conjunction with the introduction of the graphics calculator. The
results suggest that it is possible to reduce the use of questions assessing routine procedures (mechanical skills) with a
graphics calculator, but it is also evident that there have not been major changes in the way that examination questions are
written nor the mathematics skills which the questions are intended to assess. 相似文献

This study investigates how the use of calculators during high school mathematics courses is associated with student performance in introductory college calculus courses in the USA. Data were drawn from a nationally representative sample of 7087 students enrolled in college calculus at 134 colleges and universities. They included information about students’ demographics, standardized test scores, and high school mathematics course enrollment and performance. Factor analysis reduced ten items describing high school calculator usage to two composites: how extensively calculators were employed and teacher-imposed restrictions on their use. Hierarchical linear models predicted students’ college calculus grades, reported by their professor, while controlling for differences between colleges and student backgrounds. The more extensively students had used calculators in high school, the lower their grade in college calculus. However, students earned higher college calculus grades to the extent that their high school teachers had limited calculator use on quizzes and exams and had restricted calculator use until paper-and-pencil methods had been mastered, which offset the negative association of extensive calculator use with grades. The effect sizes of both calculator composites were very small. Overall, the findings raise doubts about any substantial long-term effects on college mathematics performance of calculator use in high school. 相似文献

Interactive mathematics using mathematical notation on the Web have up to now not been possible. The development to the XML-standard MathML and also the use of JAVA servlet containers have made it possible to use the Web as an advanced calculator using numeric, graphic and symbolic mathematics interactively. In connection with mathematical e-learning for engineering students this will represent quite a quantum step. In many European countries both the number of students in mathematical courses generally and the number passing through the exams has reached a ‘dangerously’ low level and industry and schools are complaining. To meet this challenge the pedagogics and the methods of communicating mathematics will have to undergo an innovative process where new technology is important. The improvement of understanding mathematics by using interactive and personalized documents on the Web could reverse bad trends, and the problems associated with recruiting girls into engineering and mathematics also have to be emphasized through the selection of applications. 相似文献
