Parents, students, teachers, school leaders, governments and the general public need good information on how well their education systems prepare students for life. A growing commitment by governments to monitor the outcomes of education systems in terms of student achievement on a regular basis and within an internationally agreed framework led…

The purpose of this study was to find out how the scientific literacy themes are represented in the current Zambian high school chemistry syllabus, textbooks and grade twelve chemistry examination papers in an attempt to find out whether or not the chemistry course has adequate potential to contribute to the preparation of scientifically literate…

This study investigates the factorial invariance of the statewide science tests at the middle school level across the oral administration accommodation and nonaccommodated groups of students with and without disabilities. Results indicate that the factor loadings and error variances are invariant across groups, although the oral administration and…

The purpose of this study was to investigate the effectiveness of Interactive Lecture Demonstrations over traditional instruction on university students' understanding of heat and temperature. The participants were 327 first year undergraduate students from two science classes in two academic years from the same university in Thailand. One class…

The paper compares the nature of the textual construction of the Programme for International Student Assessment (PISA) science test items and the Greek school science textbooks. This nature is determined by the interplay of the notions of classification (content specialization) and formality (code specialization) modulated by both the linguistic…

In this paper I compare the performance of online versus traditional on-campus students on identical exams in an earth science class. The number of college level distance learning classes offered online continues to increase as they offer greater scheduling flexibility to students, they appeal to students who like to work independently, and allow…

Preparing students to take informed positions on complex problems through critical evaluation is a primary goal of university education. Socioscientific issues (SSI) have been established as effective contexts for students to develop this competency, as well as reasoning skills and content knowledge. This mixed-methods study investigates the…

The No Child Left Behind Act increases pressure on schools and districts to use standardized state test data. Seeking to learn about the process of turning accountability data into actionable information, this paper presents findings from three case studies of small to medium sized school districts. The study examines the flow of state science…

This article considers the relationship between gender and self-efficacy in teacher trainees engaged in an electricity-related design and construction task. Quantitative data (examination scores, task assessment, and questionnaire) and qualitative data (interviews and written student reflections) were collected. There is a gender bias in student…

The No Child Left Behind (NCLB) Act requires states to measure the adequate yearly progress (AYP) of each public school and local educational agency (LEA) and to hold schools and LEAs accountable for failing to make AYP. Although it is required that science be assessed in at least three grades, the achievement results from science examinations are…

This paper provides a detailed description and evaluation of a three-year professional development project in a large urban setting in the southwestern United States. The impetus for the project was curriculum development focused on integrated scientific inquiry. Project goals included the development of a professional learning community, reformed…

To improve student science achievement in the United States we need inquiry-based instruction that promotes coherent understanding and assessments that are aligned with the instruction. Instead, current textbooks often offer fragmented ideas and most assessments only tap recall of details. In this study we implemented 10 inquiry-based science…

Current science assessments typically present a series of isolated fact-based questions, poorly representing the complexity of how real-world science is constructed. The National Research Council asserts that this needs to change to reflect a more authentic model of science practice. We strongly concur and suggest that good science assessments…

Many articles and reports have reviewed, researched, and commented on international assessments from the perspective of exploring what is relevant for the United States' education systems. Researchers make claims about whether the top-performing systems have transferable practices or policies that could be applied to the United States. However,…

Concerns over science education in the United States continue to grow due to the increasing global demands and competitiveness for careers in science and technology. This author contends that educators in the United States must look for ways to increase science proficiency and overall science literacy. Research about how students learn science…
