The aim of this study is to develop an integrated scientific and mathematical model that is suited to the background of Turkish teachers. The dimensions of the model are given and compared to the models which have been previously developed and the findings of earlier studies on the topic. The model is called the balance, reflecting the…

Background: The context is the new Texas STAAR end-of-course testing program. Purpose: The authors developed a logistic regression model to predict who would pass-or-fail the new Texas chemistry STAAR end-of-course exam. Setting: Robert E. Lee High School (5A) with an enrollment of 2700 students, Tyler, Texas. Date of the study was the 2011-2012…

"ARIES: Exploring Motion and Forces" is a physical science curriculum for students in grades 5-8 that employs 18 inquiry-centered, hands-on lessons called "explorations." The curriculum draws upon students' curiosity to explore phenomena, allowing for a discovery-based learning process. Group-centered lab work is designed to…

Retention of an introductory general chemistry course material is vital for student success in future chemistry and chemistry-related courses. This study investigated the effects of clickers versus online homework on students' long-term content retention, examined the effectiveness of online homework versus no graded homework on…

The aim of this study is to examine the effectiveness of an intervention based on a series of laboratory activities enhanced with concept cartoons. The purpose of the intervention was to enhance students' understanding of acid-base chemistry for eight grade students' from two classes in a Turkish primary school. A pretest-posttest non-equivalent…

This study examined the effects of an inquiry-based learning (IBL) approach compared to that of a problem-based learning (PBL) approach on learner performance, attitude toward science and inquiry ability. Ninety-six students from three 7th-grade classes at a public school were randomly assigned to two experimental groups and one control group. All…

School-based prevention and promotion interventions (SBPPI) improve desirable outcomes (e.g., commitment to school and attendance) and reduce undesirable outcomes (e.g., suspensions and violence). Unfortunately, our understanding of how to effectively implement and sustain SBPPI outside of well-controlled conditions is lacking. To bridge this…

Formalised peer-to-peer collaboration and the use of web-enhanced materials that are consistent with course objectives, graded assessments and learning outcomes is well known in educational practice. This study compared the academic gains of college students enrolled in Physics using Reciprocal Peer Tutoring (RPT) with others using non-Reciprocal…

We investigated the relationship between four inquiry-based teaching practices (use of: (1) models or applications, (2) hands-on activities, (3) interaction and (4) independent investigations) and science achievement for 15-year olds across eight countries participating in the Program for International Student Assessment (PISA) 2006. Within each…

This study evaluated the benefits of item enhancements applied to science-inquiry items for incorporation into an alternate assessment based on modified achievement standards for high school students. Six items were included in the cognitive lab sessions involving both students with and without disabilities. The enhancements (e.g., use of visuals,…

Providing students with assignments that focus on critical thinking is an important part of their scientific and intellectual development. However, as class sizes increase, so does the grading burden, prohibiting many faculty from incorporating critical thinking assignments in the classroom. In an effort to continue to provide our students with…

News media often publish comparative studies that report U.S. student performance in a global context. The school quality concern seems so simplistic that anyone who had compulsory education can chime into the discussion. In this article, the condition of U.S. education is further disentangled across the boundary of K-12 and higher education. Core…

Education is one of the fundamental and critical indices of development in a nation or an individual. The challenges post by our fast changing and dynamic world informed the need to constantly access the educational process so as to guarantee quality of educational assessment; several factors have been identified to be responsible for students'…

There is ample evidence to suggest that American schools perform worse than schools in many other countries. The U.S. ranks toward the bottom of the industrialized nations on international tests of academic achievement in science and mathematics. Not only may American schools perform worse but they may do so at the same time as they use more…

Even if national and international assessments are designed to be comparable, subsequent psychometric analyses often reveal differential item functioning (DIF). Central to achieving comparability is to examine the presence of DIF, and if DIF is found, to investigate its sources to ensure differentially functioning items that do not lead to bias.…
