Astronomy Resources, Thomas Hockey

Iowa Science Teachers Journal

A visual survey of all nine major planets is a standard way of beginning a series of lessons in solar-system astronomy. One of the pitfalls of such a slide program is that the different worlds of the Solar System tend to blur together in students' minds. To separate my topics, I have prepared a set of title slides. The street sign motif underscores the theme of "touring" the Solar System.

A Handbook For Secondary Teachers Of Remedial Mathematics In Georgia, Diane Koart

Theses and Dissertations

Several changes affecting the context of mathematics education were identified in Reshaping School Mathematics (Mathematical Sciences Education Board National Research Council [MSEB], 1990). The need for mathematics has changed to demand a higher level of quantitative literacy. New mathematics has been discovered and types of mathematical applications have increased. The development of technology has impacted mathematics greatly. Greater mathematical skills are demanded in the work place. Better understanding of how students learn and changes in international competitiveness also affect mathematics education. These changes implied the need for a new practical philosophy of mathematics education as a basis for curricular reform. …

Calculators In Special Education Mathematics Classes In A Junior High School, Celia M. Hurley

Theses and Dissertations

Very little has been written about the use of calculators by children with exceptional needs, although calculators are already being used by most adults who seldom do any but the simplest calculations by hand (Thorpe, 1988). They use calculators for everything from balancing checkbooks to computing sales tax.

Yet there are teachers and many parents who believe, says Wheatley (1984), that using calculators will lessen the opportunity for students to master basics. They believe that calculators should not be used until children become proficient with paper-and-pencil calculations. Some say that students should become facile in the use of calculators. Still …

Success In Written Expression: A Case Study, Susan Flowers Hamby

Theses and Dissertations

In order to receive a high school diploma, a student in any Georgia high school must pass the Georgia Basic Skills Test in three areas: Reading, Mathematics, and Writing. The subject of this case study is an eighteen-year-old male student who after four attempts passed the Writing portion of this test. Because this is a case study, the findings are reported in a nontraditional manner using a narrative style with first person commentary.

The Relationship Between Mathematical Self-Concept And Math Performance, Linda M. Arrington

Theses and Dissertations

Two hundred sixty-three ninth grade students in a selected high school of a selected large school district were surveyed for mathematical self-concept. The instrument used was Gourgey's Mathematical Self-Concept Scale. Mathematical Self-Concept was compared to performance as measured by numerical class grades and by achievement test scores. The results were correlated using the Pearson-r formula, and the hypothesis of a positive relationship existing between mathematical self-concept and performance was supported. The findings suggested that improving mathematical self-concept would help to improve math performance, as measured by numerical class grade.

Pretest Development For Gifted Biology Students, Paulette B. Jones

Theses and Dissertations

Public education has redirected concern for the education of a subpopulation within the public schools which have special needs rooted in their innate abilities to excel in selected areas. That subpopulation identified as gifted students has traditionally been approached with a variety of attitudes and teaching methods which may or may not have fully addressed the student's unique talents. The implementation of a comprehensive program of gifted education within the school system isa renewed commitment to provide appropriate education for this subpopulation of gifted learners and as such involves different teaching methodologies. The utilization of an individualized learning program which …

A Comparison Of Mental Strategies Used By Skilled And Unskilled Mental Calculators, Paul Swan
