初等数学教学与高等数学教学之间存在着较大的差别,在衔接过程中很容易导致学生出现两极分化的现象。面对这种情形,教师需要处理好初等数学与高等数学在教学过程中的衔接问题,引导学生顺利地完成过渡,将初等数学作为基础,更好地学习高等数学。文章主要探究初等数学与高等数学在教学中的衔接问题,旨在为新时期数学教学改革提供参考。 相似文献

A model incorporating prerequisite mathematics performance and other variables deemed to be associated with learning elementary statistics (ES) is developed. The relationship between ES performance and the explanatory variables is well represented by the logistics form. Aptitude, effort and motivation are the only significant explanatory variables of ES performance. Since prerequisite mathematics is not significant, statistical thinking at the tertiary level may be mostly intuitive and non-mathematical. Students with low aptitude experience increasing returns to effort over the first half of the feasible effort interval, while high-aptitude students experience diminishing returns at all levels of effort. The levels of effort required to achieve a minimum pass are interpreted. 相似文献

Creating an educational program that results in positive science, technology, engineering, and mathematics or STEM-oriented outcomes for all students is an important education objective and federal policy directive in the United States. In addition to developing strong mathematics foundations in Grades K–8 that are closely associated with successful STEM outcomes, intrapersonal skill development is also critical to academic and postsecondary success. Using nationally representative data from the Early Childhood Longitudinal Study, Kindergarten Class of 1998–99 the current study applied structural equation growth modeling to examine relationships among mathematics achievement in Grades K–1 and Grades 3–8, and mathematics self-concept development across Grades 3–8. Study results revealed that students reported declining levels of mathematics self-concept across the middle grades. Importantly, third grade reports of self-concept were associated with both mathematics achievement at kindergarten entry and third grade mathematics achievement; however, mathematics achievement at kindergarten entry was also associated with the development of mathematics self-concept in third through eighth grade. In addition, after accounting for mathematics achievement in Grades K–1, mathematics achievement growth in Grades 3–8 was directly associated with mathematics self-concept development across the same time period. Implications for future research, mathematics instruction, and curriculum development are discussed. 相似文献

This empirical paper considers the different purposes for which teachers use examples in elementary mathematics teaching,
and how well the actual examples used fit these intended purposes. For this study, 24 mathematics lessons taught by prospective
elementary school teachers were videotaped. In the spirit of grounded theory, the purpose of the analysis of these lessons
was to discover, and to construct theories around, the ways that these novice teachers could be seen to draw upon their mathematics
teaching knowledge-base in their lesson preparation and in their observed classroom instruction. A highly-pervasive dimension
of the findings was these teachers’ choice and use of examples. Four categories of uses of examples are identified and exemplified:
these are related to different kinds of teacher awareness.

One hundred and seventy-eight second grade students from two states (Georgia and Massachusetts) participated in an experiment in which they were randomly assigned to either (1) a computer program designed to increase fluency in addition and subtraction, (2) a program designed to improve cognitive strategy use for addition and subtraction, (3) a program that combined the fluency and cognitive strategy instruction programs or (4) a control condition. The intervention consisted of 40 half-hour sessions (2 sessions per week for 20 weeks). Prior to the intervention, and immediately following the intervention, the participants were tested on fluency, cognitive strategy use, and mathematics achievement. ANCOVAs indicated that children in the combined fluency and cognitive strategy use condition significantly improved their mathematics achievement in comparison to the control group. When we examined the impact of the intervention as a function of gender, boys appeared to benefit from the intervention, but girls did not. 相似文献

This study was designed to compare the effects of Team Assisted Individualization (TAI) and Student Teams-Achievement Divisions
(STAD) on fourth grade students’ academic achievement in and attitudes towards mathematics. Seven classes of a school were
randomly selected for this experimental study. Two of these were given instruction through TAI; two through STAD, and the
remaining three were treated as a control group. For the purpose of the data analysis regarding academic achievement, the
3 X 1 covariance analysis was used to compare the groups. As a result of this comparison, both the TAI and STAD methods were
found to have positive effects (d = 1.003 for TAI and d = 0.40 for STAD) on students’ academic achievement in mathematics. The pairwise comparisons showed that the TAI method had
a more significant effect than the STAD method. The scores for the attitude towards mathematics were analyzed by using non-parametric
statistics. As a result of this analysis, no significant difference was observed regarding students’ attitudes towards mathematics. 相似文献

Academic mathematics and mathematical knowledge needed in school teaching practice: some conflicting elements 总被引:1,自引:0,他引:1
In this article we analyze the relations between academic mathematical knowledge and the mathematical knowledge associated
with issues mathematics school teachers face in practice, according to the specialized literature, and restricted to the theme
“number systems”. We present examples that illustrate some areas of conflict between those forms of knowledge. We point out
some implications of our study for teacher education, such as: 1) the importance of making conflicts explicit and of discussing
them with prospective teachers in order to develop a professionally relevant perception of academic mathematics; 2) the relevance
of further research in order to better understand the extent of those conflicts and their effects on the process of integrating,
in a body of professional knowledge, the different kinds of mathematical knowledge presented to prospective teachers.

Our study investigates perspectives of mathematics teacher educators related to the usage of their mathematical knowledge
in teaching “Methods of Teaching Elementary Mathematics” courses. Five mathematics teacher educators, all with experience
in teaching methods courses for prospective elementary school teachers, participated in this study. In a clinical interview
setting, the participants described where and how, in their teaching of elementary methods courses, they had an opportunity
to use their advanced mathematical knowledge and provided examples of such opportunities or situations. We outline five apparently
different viewpoints and then turn to the similar concerns that were expressed by the participants. In conclusion, we connect
the individual perspectives by situating them in the context of unifying themes, both theoretical and practical. 相似文献
