Disparities in academic science performance remain for diverse learners, including students with learning disabilities and English learners. Educational technology offers the potential to support diverse learners by taking into account their specific needs and unique strengths. This paper reports on third-year results of a 3-year randomized…

Teachers are the most important school resource. In every country, teachers' salaries and training represent the greatest share of expenditure on education; and this investment in teachers can have significant returns. Research shows that being taught by the best teachers can make a real difference in the learning and life outcomes of otherwise…

In this research; aim was determining student achievement by comparing problem-based learning method with teacher-centered traditional method of teaching 10th grade chemistry lesson mixtures topic. Pretest-posttest control group research design is implemented. Research sample includes; two classes of (total of 48 students) an Anatolian High School…

This study aims to produce inquiry-oriented general physics learning material to improve student learning outcome. Development steps of learning materials were adapted from the design model of Dick and Carey. Stages of development consists of three phases: planning, development, and formative evaluation and revision. Implementation of formative…

Human anatomy has usually been taught in a didactic fashion in colleges and universities. However, recent calls from United States governmental agencies have called for the transformation of undergraduate life sciences education to include active learning in the classroom. In addition, high structure courses have been shown to increase student…

Engineers are faced with solving important problems every day and must follow a step-by-step design process to arrive at solutions. Students who are taught an effective design process to apply to engineering projects begin to see problems as an engineer would, consider all ideas, and arrive at the best solution. Using an effective design process…

A meta-analysis of recent quantitative studies that examine the effects of cooperative learning (CL) on achievement outcomes in chemistry is presented. Findings from 25 chemical education studies involving 3985 participants (N[subscript treatment] = 1,845; N[subscript control] = 2,140) and published since 2001 show positive association between…

The purpose of this cross-cultural study was to describe and compare US and Turkish children's observational knowledge of the day and night cycle and to identify similarities predicted by framework theory. Fifty-six (27 US and 29 Turkish) young children (ages 48-60 months) participated in the study. Semi-structured interviews were individually…

Recently, single-sex classes within public coeducational schools have proliferated across the USA; yet, we still know little about whether and how single-sex science classes influence adolescents' attitude and affect toward science. This exploratory study expands upon our current understanding by investigating the extent in which female and male…

The flow of genetic information from DNA to RNA to protein, otherwise known as the "central dogma" of biology, is one of the most basic and overarching concepts in the biological sciences. Nevertheless, numerous studies have reported student misconceptions at the undergraduate level of this fundamental process of gene expression. This…

Students frequently expressed difficulty in understanding the molecular mechanisms involved in chromosomal recombination. Therefore, we explored alternative methods for presenting the two concepts of the double-strand break model: Holliday junction and heteroduplex formation, and Holliday junction resolution. In addition to a lecture and…

The study examined the effect of simulation technique and lecture method on students' academic performance in Mafoni Day Secondary School, Maiduguri. The study used both simulation technique and lecture methods of teaching at the basic level of education in the teaching/learning environment. The study aimed at determining the best predictor among…

This article describes the development of a lesson sequence that supports secondary-level students to construct an explanatory model for electrostatic attraction using a guided enquiry method. The students examine electrostatic interactions at a macro level and explain the phenomena at the atomic level. Pre-tests, post-tests, homework assignments…

Field trips are an important feature of the United States' education system, although in the current context of high-stakes tests and school accountability, many schools are shifting resources away from enrichment. It is critical to understand how field trips and other informal learning experiences contribute to student test scores, but little…

Turkish students on average had lower scores than OECD countries on mathematics, science, and reading at international assessment programs. As PISA measures the extent to which 15-year-old students are prepared to handle the challenges they may encounter in their future lives, and evaluates students' ability to reflect and to apply their knowledge…
