The purpose of this research was to explore the long-term outcomes of either participating or not participating in early childhood science education on grade 6 students' conceptual understanding of science. The research is situated in a conceptual framework that evokes Piagetian developmental levels as both potential curriculum constraints and…

Background: A wide range of studies has offered suggestions why genetics is difficult and some of their key findings are summarised. Underpinning all of this is the way the brain works when handling information. The limitations of working memory capacity offer an interpretation of these difficulties. Purpose: The aim is to confirm that working…

This paper presents a problem-solving test that deals with the regulation of the "trp" operon of "Escherichia coli." Two mutants of this operon are described: in mutant A, the operator region of the operon carries a point mutation so that it is unable to carry out its function; mutant B expresses a "trp" repressor protein unable to bind…

This article reviews how practical work, including practical skills, is currently summatively assessed in school science in a number of countries and makes comparisons with how other subjects, such as music and modern foreign languages, summatively assess skills. Whilst practical skills in school science are clearly valued as being of importance,…

A stand-alone online teaching module was developed to cover an area of musculoskeletal anatomy (structure of bone) found to be difficult by students. The material presented in the module was not formally presented in any other way, thus providing additional time for other curriculum components, but it was assessed in the final examination. The…

This dissertation examines a vital catalyst in the globalization of education: international assessments--that involve testing and rankings--of student achievement in academic subjects. Nearly all high-income countries participate in international assessments such as Trends in International Mathematics and Science Study (TIMSS), Progress in…

The Program for International Student Assessment (PISA) is a system of international assessments that allows countries to compare outcomes of learning as students near the end of compulsory schooling. PISA core assessments measure the performance of 15-year-old students in mathematics, science, and reading literacy every 3 years. Coordinated by…

This paper focuses "interest in science" as one of the attitudinal aspects of scientific literacy. Large-scale data from the Programme for International Student Assessment (PISA) 2006 are analysed in order to describe student interest more precisely. So far the analyses have provided a general indicator of interest, aggregated over all…

Why has large-scale standardised testing attracted such a bad press? Why has pedagogic benefit to be derived from test results been downplayed? The paper investigates this question by first surveying the pros and cons of testing in the literature, and goes on to examine educators' responses to standardised, large-scale tests in a sample of low…

The Australian Council for Educational Research (ACER) is one of the world's leading educational research centres. ACER's mission is to create and promote research-based knowledge, products and services that can be used to improve learning across the life span. This annual report describes ACER's milestones and accomplishments for the 2014-2015…

This study investigated how the different discussion approaches in Facebook influenced students' scientific knowledge acquisition and the nature of science (NOS) views. Two eighth- and two ninth-grade classes in a Taiwanese junior high school participated in the study. In two of the classes students engaged in synchronous discussion, and in the…

The National Union of Students (NUS) National Student Experience Report identified examination feedback as an area where students had particular concerns. This finding was echoed in the authors' institution and triggered an action research project to investigate ways of improving students' perceptions of pre- and post-exam feedback. We report the…

Stereotypes, role models played by teachers and social norms influence girls' academic self-concept and push girls to choose humanities rather than science. Do recruiters reinforce this strong selection by discriminating more against girls in more scientific subjects? Using the entrance exam of a French higher education institution (the Ecole…

The purpose of the study was to explore the relationship of Texas high school principals' organizational commitment and the academic performance of the high schools served by the principals. Three components of principal organizational commitment--affective commitment, continuance commitment, and normative commitment--were assessed using the…

Background and purpose: Chemistry examinations can favour the deployment of algorithmic procedures like Le Chatelier's Principle (LCP) rather than reasoning using chemical principles. This study investigated the explanatory resources which high school students use to answer equilibrium problems and whether the marks given for examination answers…
