This study sought to determine the effect of the problem-solving approach on academic achievement of students in mathematics at the secondary level. The secondary school students studying mathematics constituted the population of this study. The students of 10th class of Government Pakistan Girls High School Rawalpindi were selected as a sample…

This study describes how two 10th grade teachers designed a cross-disciplinary unit, using PBL instruction as a tool for helping students create a valid and convincing argument in their math class. The five week PBL unit focused around American Studies/English and geometry content. In order to measure the rigor and relevance of the unit, multiple…

A critical component of science is the role of inquiry and argument in moving scientific knowledge forward. However, while students are expected to engage in inquiry activities in science classrooms, there is not always a similar emphasis on the role of argument within the inquiry activities. Building from previous studies on the Science Writing…

In Vietnamese secondary education, translation and visuals are traditionally used as major techniques in teaching new English lexical items. Responding to the Vietnamese government policy issued in 2008 on using IT for a quality education, the application of PowerPoint has been considered the most prevalent type of technology used in the…

Virtual K-12 schools have rapidly become a popular choice for parents and students in the last decade. However, little research has been done on the instructional practices used in virtual courses. As reflected in the central research question, the purpose of this study was to explore how teachers provided instruction for Grade 7-10 students in…

This case study analyzed the ways a native Spanish speaker of high-beginning English proficiency and his teacher negotiated an extended writing task in a tenth-grade mainstream humanities course. An "interactional histories" analysis demonstrated the teacher's pedagogical and conversational moves to adapt the academic task and the moves…

This study proposed to investigate the effectiveness of learning activities based on a conceptual change theoretical framework by embedding a peer instruction method with structured inquiry (PISI) on tenth grade students' understanding of force and motion concepts. This teaching method was compared to the existing traditional instruction (TI).…

It is considered valuable to take advantage of web activities to improve and qualify the English teaching and learning processes, especially in the promotion of reading comprehension. In this article we share the process and results of a study that focused on some activities based on web materials that were designed and used with 10th grade…

This paper presents a series of illustrative LEGO Mindstorms-based science and math activities, developed under an NSF GK-12 Fellows project, for elementary, middle, and high school grades. The activities, developed by engineering and science graduate Fellows in partnership with K-12 teachers, are grade appropriate, address pertinent learning…

Conceptions of literacy in the secondary English language arts classroom today have expanded in multiple directions, moving far beyond former emphases on reading comprehension and writing ability. This article presents the efforts of two secondary English language arts teachers in the Midwestern United States to expand the meaning of literacy in…

For many years, education in South Africa has been based mainly on western values. This has contributed to the fact that many learners from disadvantaged backgrounds cannot see the connection between the education they receive at school and their everyday experiences. This may well have contributed to the high failure rate amongst mathematics…

This study examined whether the application of conceptual change texts are effective before or after the instruction on 10th grade students' conceptual understanding and alternative conceptions about acids and bases. The study was conducted with 76 10th grade students from three classes of a chemistry course taught by the same teacher. One of the…

This study investigated the effectiveness of a web-based learning environment in enhancing 10th grade high-school students' understanding of the concept of "chemical bonding". Two groups participated in this study: an experimental group (N = 161) and a comparison one (N = 93). The teachers in the experimental group were asked to implement four…

The aim of this study is to investigate the effectiveness of conceptual change oriented instruction (CCOI) over traditionally designed chemistry instruction (TDCI) on overcoming 10th grade students' misconceptions on gases concepts. In addition, the effect of gender difference on students' understanding of gases concepts was investigated. The…

Conversations with Josh, a mentee of the author, and other gifted students caused the author to realize that in many cases, what is presented as appropriately differentiated language arts curriculum for gifted/talented students is nothing more than general education curriculum with additional work at the same level as the regular curriculum. If…
