This paper argues that operations with negative numbers should be taught using a curriculum that is grounded in algebraic geometry. This position is supported by the results from a study that compared the conceptual understanding of grade 9 students who received the Algebra Project transition curriculum to a control group of grade 6 gifted…

This unit is one of a series that presents specific moments in history from which students focus on the meanings of landmark events. Columbus's momentous arrival in 1492 in the Caribbean ended the mutual isolation of two regions of the globe. From this moment on, the future of the Americas has been inextricably linked to those of Europe, Asia, and…

In 1993-94, the Austin (Texas) Independent School District (AISD) allocated money to four operations areas for five dropout prevention programs for overage ninth graders. Three of the five area dropout programs had positive effects on the dropout rates of students served. The dropout rates for these programs were lower than the sixth six-weeks…

Confirmatory Factor Analysis was used to test first- and second-order factor models on cognitive abilities and their invariance across male and female samples. Subjects were a stratified random sample of 234 male and 225 female 15-year-old students in Singapore attending Secondary 3 (the equivalent of grade 9). Four first-order factors were found…

Eighty ninth graders who solved an algebra problem in groups of four showed status effects at the individual level. The students had filled out preactivity questionnaires about mathematical status and social status and a postactivity leadership questionnaire. Hierarchical regressions and path analyses show that, at the group level, solution score…

This study integrated three major areas in understanding children's and young adults' metamemory components, self-efficacy, implicit theories, and performance-predictions. These areas were examined in relation to a picture recall task which was performed children at three age levels. Further, empirically-based "start value" information regarding…

This report describes a project that is part of a national assessment program in Sweden under which the performance and attitudes of students in the 5th and 9th years of the compulsory school are being studied. The study focuses on the description of classroom activities and attained goals as well as on attitudes towards the subject, English as a…

Although the results of minimum competency tests need to be interpreted with caution, data on the Texas Assessment of Basic Skills (TABS) for 1980-82 clearly indicate the inadequate results of remedial programs for minority students in Texas. Secondary analysis of the data shows that overall performance on exit level math and reading tests…

One of a series of six portraits of high school literature classrooms, this paper gives a detailed, evocative characterization of how one "master teacher" introduced, undertook, and guided the study of literature, focusing in particular on how the teacher interacted with students in the context of discussion of a literary work in class.…

A procedure was developed to detect differential item functioning (DIF) in a standardized essay test using the Partial Credit Model, the general polychotomous form of the Rasch model. Using a panel of experts in the writing process, hypothesized explanations for DIF at some score points were developed. Data for the study included averaged…

This study investigated the relationship between locus of control orientation and adoption of cigarette smoking among ninth grade urban black Southern students. It sought to identify this relationship and determine if school-setting (junior or senior high school) or gender-related differences exist. The following information was used to assess…

These career exploration curriculum guides are designed to provide infusion activities for entry-level academic courses at the high school level. Guides are provided for the areas of art, English, foreign language, mathematics, biological science, physical science, and social studies. Each guide is related to an occupational cluster and specific…

A study of self-correction, or repair (the righting of the trouble source) among bilingual secondary students differed from most repair studies in three ways. It: (1) examined results in the form of description rather than in quantifiable analyses; (2) defined errors as trouble sources (hearable errors, breaks in communication such as word…

Intended for both teachers and students, this bulletin presents specific information about the design, parts, and scoring of the Grade 9 English Language Arts Achievement Test for the 1985-86 school year in Alberta, Canada. General information is presented regarding the (1) purpose and nature of the Achievement Testing Program (ATP), (2) students…

The current New Jersey high school graduation law requires that students pass a ninth grade test in reading, writing, and mathematics. Equating the writing test from year to year to be sure that passing scores remain identical, regardless of the test form administered, requires developing a scoring technique. A research study was developed based…
