Reports on the strategies adopted by a group of teachers in Ontario, Canada as they implemented de-streaming with grade 9 classes. Indicates that teachers were found to be making special provisions for both low- and high-achieving students and employing a wide range of techniques for assessing student progress. (Contains 20 references.)…

This project describes the trialling of a new form of cooperative learning strategy, in the form of a game known as "EcoRangers". "EcoRangers" is a multi-player game designed to run on mobile phones, written specifically for education. "EcoRangers" is one of the first, if not the world's first, instances of this…

The conditions under which explicit instruction in checking, combined with worked examples, may be beneficial in learning how to translate sentences into algebraic equations was examined from the perspective of cognitive load theory. In two experiments it was shown that Grade 8 and 9 students were initially disadvantaged by the inclusion of a…

In the present article, we argue that the conceptual change approach to learning can apply in the case of mathematics, taking into consideration the particular nature of mathematical knowledge and the neurobiological bases of mathematical cognition. In the empirical study that is reported in this article, we investigated ninth graders'…

Two hundred and thirty-one students in six Grade 9 classes in two government secondary schools located near Chiang Mai, Thailand, attempted to solve the same 18 quadratic equations before and after participating in 11 lessons on quadratic equations. Data from the students' written responses to the equations, together with data in the form of…

The Aplusix system has been designed for helping students to learn algebra. Its capacity to tell the students whether their calculations are correct or not, to provide families of exercises of a chosen level, and to give scores after tests allows this system to be used in the regular functioning of the class. Its capacity to record the students'…

Physics First has gained momentum across the country. Providing a radically different paradigm to teaching science at the high school level, the Physics First movement inverts the traditional science sequence by teaching physics to ninth grade students. One of the benefits of this change, supporters claim, is that it provides a foundation to teach…

A CURRICULUM GUIDE FOR NINTH-GRADE SOCIAL STUDIES IS PRESENTED. IN TEACHING SOCIAL STUDIES THERE SHOULD BE A BALANCE BETWEEN THE TEACHING OF FACTS, AND THE TEACHING OF INTELLECTUAL DISCIPLINES AND FOUNDATION LEARNINGS THAT ARE PREREQUISITE TO UNDERSTANDINGS. IN THE CLASSROOM, THE CHILDREN SHOULD BE ENCOURAGED TO PRACTICE THE PRINCIPLES OF FREE…

Three blocks of classroom materials were developed, taught, and evaluated in ninth grade physical science classes of the San Antonio Independent School District. Concepts involving measurement, ratio, and mapping were taught by laboratory investigations to an experimental group of 27 classes (N = 527). Twenty-one control classes (N = 399) studied…

The purpose of this study was to determine whether the use of electric calculators offered an effective remedy for the lack of success and the corresponding negative attitude of the low achiever in mathematics. Two hundred and one low achievers were randomly scheduled into one of five control sections or into one of five experimental sections.…

A remedial instructional strategy (developed and implemented in ninth-grade physics classes) was found to significantly affect low/mixed ability students' achievement. The method was developed on the basis of a needs assessment of students' backgrounds and a detailed task analysis of the physics course's cognitive demands. (JN)

The development, implementation and assessment of a teacher-developed individualized learning program for two ninth grade physical geography classes are reported. (KM)

An evaluation of six teaching methods revealed that the most effective method of teaching career information appeared to be the use of an Audiscan projector, a teaching plan, and an inservice visit by a subject matter specialist. (SB)

Recounts the details of a teacher's feelings about leaving her class to go on jury duty. Tells how she related her jury experiences to the class and had the students interpret information from a short story in a mock courtroom presentation. (RL)
