Rate is an important, but difficult mathematical concept. More than twenty years of research, especially with calculus students, report difficulties with this concept. This paper reports on an alternative analysis, from the perspective of multiple representations and context, of interviews probing twenty Victorian Year 10 students' conceptions of…

The purpose of this study was to investigate Grade 10 Thai students about their understanding on inter- and intramolecular forces. Sixty four students were elicited by administered open-ended questions after finishing normal instruction on chemical bonding topics. The instrument was in a set of open-ended questions which contained a number of…

This study uses the Mathematical Tasks Framework (Stein & Smith, 1998) to assess the cognitive demand of mathematical tasks implemented in four mathematics classrooms, and to investigate the role of technology in both low- and high-level cognitive demand tasks. The metaphor of using technology as an amplifier or reorganizer (Pea, 1987) is used…

This paper reports on an evaluation of a distinctive university-school partnership program, Curriculum Bridges. Curriculum Bridges aims to develop the enthusiasm and capacity of students from disadvantaged schools in the fields of science, technology, engineering and mathematics (STEM). These objectives are sought by developing a theme in the…

This study was conducted to determine the views of high school students about proof and these students' levels of proof. Case study method was used in this descriptive study. The data of the study were obtained by conducting a questionnaire which consists of eight open-ended questions to total 125 10th grade students studying in two different…

In this paper we present the results of an evaluation study of a development project for the introduction and use of tablet computers (iPads) at the lower secondary level in Nordlinga school, a compulsory school in Reykjavík. In the study, we assess the impact of the use of tablet computers on instruction and students' learning in grades 9 to 10,…

Significant momentum exists for next-generation assessments to increasingly utilize technology to develop and deliver performance-based assessments. Many traditional challenges with this assessment approach still apply, including psychometric concerns related to performance-based tasks (PBTs), which include low reliability, efficiency of…

In the era of mobile devices and services, researchers in the educational domain have been interested in how to support learning with mobile technology in both local and global contexts. Recent human-computer interaction (HCI) research in the educational domain has particularly focused on how to develop mobile learning services and how to evaluate…

The purpose of the current investigation was to establish the validity of microanalytic measures used to assess students' self-regulation of an academic science task, not only in terms of immediate achievement, but also in terms of a well-established "person" measure of self-regulated learning. Person measures are designed to capture enduring…

This study examined one public school system's change in its bell scheduling format from a seven period day to block scheduling. The data collected was from a three year period of the grade 10 students passing the Massachusetts Comprehensive Assessment System exam. Students in Massachusetts must pass the mathematics and English/language arts…

Recent research has suggested that differences between intelligent tutor lessons predict a large amount of the variance in the prevalence of gaming the system. Within this paper, we investigate whether such differences also predict how much students choose to go off-task, and if so, which differences predict how much off-task behavior will occur.…

Queensland Academy for Health Sciences (QAHS) is a senior secondary high school offering the International Baccalaureate (IB) Diploma Programme (DP). As part of the Diploma, students are required to complete a referenced research essay of four thousand words. For most, this will be their first experience of such a challenging undertaking.…

This study documents the impact of placing graduation coaches as a GEAR UP intervention in urban high schools. The overall goal was improvement of students' academic performance, particularly for students not passing core courses. This longitudinal study began with data collection in feeder middle schools where results indicated improved student…

This qualitative research case study examined the supports required for 31 academically average 10th grade students to succeed on three dual enrollment college courses. Conceptually, support was a team effort, with contributions considered from administrators, faculty, parents and students. The paper documents support contributions from all four…

This study was an expanded replication of an earlier endeavor (Shermis, Burstein, & Bliss, 2004) to document the writing outcomes associated with automated essay scoring. The focus of the current study was on determining whether exposure to multiple writing prompts facilitated writing production variables (Essay Score, Essay Length, and Number…
