The inadequacy of experimental activities (or lack of equipment) in science courses in rural parts of Turkey negatively effects students' acquisition of scientific thinking and inquiry skills. The fact that success rates are notably low in international assessments demonstrates the necessity to adopt "different" approaches apart from the…

This study focused on the extrinsic and intrinsic motivation levels of eighth grade students and its relationship with their mathematical achievement. The participants of the study included 6,829 students who took TIMSS in 2011 and 239 mathematics teachers. The data obtained from the student and teacher questionnaires that are included in the…

In this study the authors set out to better understand the relationship between teacher knowledge of science and student learning. The authors administered identical multiple-choice assessment items both to teachers of middle school physical science and to their students throughout the school year. The authors found that teachers who have strong…

In 2015, PISA and TIMSS are coming up to us together. In this study, the data from PISA and TIMSS are used to investigate that which one is a better indicator of national science and technology (S&T) competitiveness? Number of S & T journal articles (per million people) is used as a measure to represent the national S&T…

We examined the age of onset, over-time dynamics, and mechanisms underlying science achievement gaps in U.S. elementary and middle schools. To do so, we estimated multilevel growth models that included as predictors children's own general knowledge, reading and mathematics achievement, behavioral self-regulation, sociodemographics, other child-…

Using data from the 2011 (Chinese) Student Academic Achievement Evaluation, we examined whether within-school socioeconomic gaps in science achievement exist across science subjects, how consistent they are, and whether there are relationships between school average science achievement and within-school socioeconomic gaps in science achievement.…

Attention deficit hyperactivity disorder (AD/HD) is one of the most frequently occurring disorders in school children, and information and communication technology (ICT) in education is one of the tools that is lately considered as helpful for the education of some children with disorders. This research is a case study--using mixed-methods--of the…

Researchers have confirmed that students' motivation is one of the most important factors educators can target to improve learning (Williams & Williams, 2011). This study explored the role which student's motivation played in the retention of first-time, full-time freshman (FTFTF) STEM majors at University (U) (blinded). Student motivational…

This paper explored the Relevance of the Pedagogy and Academic Content Knowledge that are offered to Prospective Science and Mathematics Teachers in Tanzania Teachers' colleges. Morogoro Teachers' College and Kleruu Teachers' college were used as a case study. The performance in science and mathematics subjects in form four National examinations…

The purpose of this study was to examine the impact of dimensionality, common-item set format, and different scale linking methods on preserving equity property with mixed-format test equating. Item response theory (IRT) true-score equating (TSE) and IRT observed-score equating (OSE) methods were used under common-item nonequivalent groups design.…

The purpose of this paper is to examine the effects of WebQuests on elementary students' science achievement, attitude towards science and attitude towards web supported education in teaching 7th grade subjects (Ecosystems, Solar System). With regard to this research, "Science Achievement Test," "Attitude towards Science Scale"…

The study aims to investigate the effect of using constructivist learning model in teaching science, especially in the subject of light: its nature, mirrors, lens, and properties, on the achievement of eighth-grade students and their scientific thinking. The study sample consisted of (136) male and female 8th graders were chosen from two basic…

There is a growing demand for degreed science, technology, engineering and mathematics (STEM) professionals, but the production of degreed STEM students is not keeping pace. Problems exist at every juncture along the pipeline. Too few students choose to major in STEM disciplines. Many of those who do major in STEM drop out or change majors.…

The aim of this study is to analyse the effects of scientific argumentation based learning process on the eighth grade students' achievement in the unit of "cell division and inheritance". It also deals with the effects of this process on their comprehension about the nature of scientific knowledge, their willingness to take part in…

The SUN approach to biological energy transfer education is fundamentally different from past practices that trace chemical and energy inputs and outputs. The SUN approach uses a hydrogen fuel cell to convince learners that electrons can move from one substance to another based on differential attraction. With a hydrogen fuel cell, learners can…
