This document contains curriculum specifications for grade 9. Objectives are grouped under seven broad topic areas. For each objective and each topic area a percent of emphasis is given. The broad topic areas and percent emphasis for each of those areas are: (1) number systems, 22 percent; (2) ratios and proportions, 10 percent; (3) measurement, 6…

The Remedial Mathematics Skills Program funded under Elementary and Secondary Education Act Title I serviced students who were two or more years below grade level in mathematics in 50 New York City high schools for the 1974-1975 school year. The program objective was to improve students' computational skills through the use of calculators,…

This paper describes how a researcher developed task and four different data collection instruments provide evidence for the identification of various affordances of a technology-rich teaching and learning environment (TRTLE) that were perceived and/or enacted by Year 9 students in their solution of a linear function task utilising a graphing…

Presents results of a survey among ninth graders, focusing on their perception of mathematics instruction and their mathematics teachers. Shows that their perception of teachers is related to the characteristics of the quality of instruction. Discusses including survey responses of students on school instruction in scholastic systems of quality…

Presents an activity to introduce students to the intrinsic curvature of surfaces using a wide variety of objects. Describes student discoveries, several variations on the project, and possible classroom discussion topics. A reproducible student worksheet and 17 references are included. (MKR)

Little is known about the feasibility and rapidity with which the academic learning of students who enter high school multiple years behind grade level can be accelerated. This study uses multiple regression analyses of standardized test and survey data from high-poverty high schools in two large urban districts to evaluate initial effects of the…

The Sequential Mathematics Sequence provides an integrated course of study for grades 9-11 in New York City. This document presents lesson plans for part two of the first-year course, designed for ninth grade. The curriculum interweaves algebra, geometry, logic, probability, statistics, and trigonometry, with the emphasis in the 60 lessons in this…

This study used 152 grade eight students ranging in age from 12 to 14 years from a suburban middle school in central New Jersey. The investigations gave particular attention to the identification of variables that represent understanding of fundamental mathematical structures. The first year of the research took place during the 1978-1979 school…

The purpose of the study was to find out if and how the subject matter of a remedial high school classroom interacted with the social organization of that classroom and the differences it made. Two classrooms with different subject matter (mathematics and social studies) were observed over the course of a school year. The multiple awarenesses and…

THE JUDGMENTS OF TEACHERS AND THEIR REACTIONS TO THE EXPERIMENTAL MATHEMATICS PROGRAMS THEY WERE TEACHING IN CONNECTION WITH A PROJECT WHICH EVALUATED SEVERAL RECENTLY DEVELOPED PROGRAMS WERE OBTAINED AND ANALYZED. OBSERVATIONS AND JUDGMENTS ABOUT THESE PROGRAMS WERE OBTAINED THROUGH A QUESTIONNAIRE SENT TO TEACHERS WHO PARTICIPATED IN ONE OF THE…

THE EXPERIMENTAL DESIGN IN THIS STUDY OF THE USE OF PROGRAMED MATERIALS TO TEACH HIGH SCHOOL MATHEMATICS DESIGNATED FOUR GROUPS--A CONTROL GROUP TAUGHT CONVENTIONALLY BY TEACHERS TRAINED TO USE PROGRAMED MATERIALS, A "PURE" GROUP USING PROGRAMED MATERIALS ONLY, AND "ANTICIPATING" AND "FOLLOWING" GROUPS THAT USED…

Findings of a 1989 research study on LOGO-based instruction for teaching abstract concepts of geometry are reported in an effort to encourage mathematics teachers to use the LOGO language in computer-assisted instruction. Thirty-three ninth graders (19 males and 14 females) (6 white students and 27 black students) were involved in the controlled…

This report presents findings from a study of the cognitive processes and learning difficulties of ninth-grade students in Algebra I. A clinical interview approach was used with 14 students. A group of six Hispanic students and a group of five Anglo students were enrolled in the same algebra class; three Hispanic students were enrolled in an…

This document reports in detail an investigation of the cognitive processes and learning difficulties of ninth-grade students in Algebra I. A clinical interview approach was used with 14 students. A group of six Hispanic students and a group of five Anglo students were enrolled in the same algebra class; a group of three Hispanic students who had…

This study investigated the impact of a student-tutor and parent interaction program on the achievement scores of ninth- and tenth-grade Algebra 1 and general biology classes. Past studies have shown that student-parent interaction in academic areas can produce significant increases in achievement scores. There is, however, very little evidence of…
