This study is a secondary analysis of data from the 1995 administration of the Third International Mathematics and Science Study (TIMSS). The purpose is to compare the breadth, depth, and recurrence of the typical physics curriculum in the United States with the typical curricula in different countries and to determine whether there are…

The current study aimed at examining the efficacy of technological projects as learning tools by exploring the following questions: the extent to which projects in technology develop students as independent learners; the types of knowledge the students deal with in working on their projects; the role of problem-solving in technological projects;…

This study examines whether the Problem Based Economics curriculum developed by the Buck Institute for Education improves grade 12 students' content knowledge as measured by the Test of Economic Literacy, a test refined by the National Council on Economic Education (NCEE) over decades. Students' problem-solving skills in economics were also…

The purpose of this research project was to use an experimental design research methodology to compare learning and attitudinal effects of two different design instructional strategies on randomly selected and assigned 11th and 12th grade students. Through the use of a common technological based problem, students were guided through a design…

This study reports findings from an analysis of the 2002 Chinese National Physics Curriculum Guidelines and the alignment between the curriculum guidelines and two most recent provincial-level 12th-grade exit examinations in China. Both curriculum guidelines and test content were represented using two-dimensional matrices (i.e., topic by level of…

In this paper we explore the influence of students' personalized notion of "small" numbers based on real life experiences on their understanding of limits. Tests were conducted on two samples of students. The first sample, consisting of students in the XII grade, had been taught limits using an informal approach (i.e., without recourse to the…

Our main goal in this study was to determine whether the use of computer animation and illustration activities in high school can contribute to student achievement in molecular genetics. Three comparable groups of eleventh- and twelfth-grade students participated: the control group (116 students) was taught in the traditional lecture format,…

According to the national results of the English diagnostic test (2004) applied to Chilean 8th and 12th graders, the current English teaching methodology used in this country is not efficient nor effective. Consequently, a different methodology is urgently needed, particularly in a context where students primarily come from rural areas and will be…

Constructivist pedagogies are generally not considered to support the teaching of mathematics for externally assessed examination-based courses. In large part, teachers have believed that such approaches are inefficient in covering a set syllabus. This article summarises the author's learning journey in Year 12 mathematics in 2004 where attempts…

Two different teaching methods were compared for their effectiveness on the writing skill and attitudes of twelfth graders. The sample included 135 randomly assigned students in six classes of an elective precollege writing course, with no significant differences between the students on the basis of ability or attitude. Traditionally oriented…

The purpose of this study was to investigate the meanings that a teacher associated with calculators as reflected in the teacher's use of calculators in two 12th-grade mathematics courses, and to link those meanings to the institutions and individuals that supported the development of those meanings. By describing the teacher's conceptions of his…

Since 1995, astronomers have discovered over 100 known exoplanets--planets outside of the solar system--and determined their properties such as mass, orbital distance, size, and density. By using simple algebraic equations of physics, students can determine these properties as well. In this article, the author discusses an activity titled…

This study examines Indonesian students' understanding of conservation of matter, balancing of equations and stoichiometry. Eight hundred and sixty-seven Grade 12 students from 22 schools across four different cities in two developed provinces in Indonesia participated in the study. Nineteen teachers also participated in order to validate the…
