In Joe Crawford's last two articles, he examined the process of building standards-based curriculum documents to drive instruction in the K-8 environment. Continuing with this theme, this article explores "closing the loop" and following this work into the high school experience. There is one huge difference in the Common Core State…

A parabola is an interesting curve. What makes it interesting at the secondary school level is the fact that this curve is presented in both its contexts: algebraic and geometric. Being one of Apollonius' conic sections, the parabola is basically a geometric entity. It is, however, typically known for its algebraic characteristics, in particular…

This study examines the relationship between performance on Utah's English proficiency assessment and English language arts and mathematics content assessments by English language learner students and compares the performance of English language learner and non-English language learner students on the content assessments. Two research questions…

Eighty tenth-graders studied a two-day unit on quadratic inequalities presented in one of four programmed-booklet forms: analytic treatment with advance organizer, analytic treatment plus introductory overview, graphical treatment with advance organizer and graphical treatment with introductory overview. No differences were found between groups on…

This study investigated the effects of specific criteria for marking a test on its reliability and validity. Eight algebra word problems were administered to grade 10 students. The objectivity of scoring criteria improved the reliability of the test, but did not affect its validity. (MNS)

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…

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 second-year course, designed for tenth grade. The curriculum interweaves algebra, geometry, logic, probability, statistics, and trigonometry, with the emphasis in the 60 lessons in…

Lesson plans for teachers of ninth and tenth grade students contained in this guide are organized according to subject (algebra), instructional topic, career education developmental area, instructional goal, developmental goal, performance objectives, activities, and resource materials. The seven developmental areas of career education are listed…

This curriculum guide covers Course II of a three-year sequence for high school mathematics in New York which was intended to provide an alternative to the regular Regents' sequence of ninth-, tenth-, and eleventh-grade mathematics. A listing of scope and content is provided along with suggested time allotments. Topics covered are: Logic,…

Identified and classified solution strategies of (n=49) 10th-grade students who were presented with linear programming problems in a predominantly visual setting in the form of a computerized game. Visual strategies were developed more frequently than either algebraic or mixed strategies. Appendix includes questionnaires. (Contains 11 references.)…
