Scientific inscriptions--graphs, diagrams, and data--and argumentation are integral to generating and communicating scientific understanding. Scientific inscriptions and argumentation are also important to learning science. However, previous research has indicated that learners struggle to understand and learn science content represented in…

The topic of Newtonian gravity offers a unique vantage point from which to investigate and encourage conceptual change because it is something with which everyone has daily experience, and because it is taught in two courses that reach a wide variety of students--introductory-level college astronomy ("Astro 101") and physics ("Phys…

In 19 (sub)samples from seven countries (United States, Austria, Germany, Costa Rica, Ecuador, Vietnam, Brazil), we analyzed the impact of parental education compared with wealth on the cognitive ability of children (aged 4-22 years, total N = 15,297). The background of their families ranged from poor indigenous remote villagers to academic…

Purpose: To advance a framework of indicators that promotes implementation of math standards under the Every Student Succeeds Act (ESSA), we tested a conceptual model of the resources and processes within schools that influence the opportunity to learn mathematics (OTL) in the classroom using a recent administration of the 2011 Trends in…

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 2016-2017…

In this study, we investigated gender and minority achievement gaps on 8th-grade science items employing a multilevel item response methodology. Both gaps were wider on physics and earth science items than on biology and chemistry items. Larger gender gaps were found on items with specific topics favoring male students than other items, for…

Romania's education system has made impressive strides over the past two decades, with an increasing share of students mastering the basic competencies that they need for life and work. But these average improvements mask significant disparities in learning outcomes and attainment, with an increasing share of students leaving education early…

International achievement comparison studies assess students on core subjects such as Reading, Mathematics and Science. Students who do not speak the test language at home can be expected to be disadvantaged because of language proficiency. The test language effect has not been given sufficient attention. The present study investigated probable…

The rise of the PISA standards has taken the educational world by storm, with intense media attention and debate every time they are published. Over the past two decades, they have been gaining an increasing role in shaping educational systems and policies across the world, gaining a "canonical status" among member countries, and…

Over the past eight years we have undertaken iterative cycles of course reform in two introductory biology courses: Biology 111 and Biology 211. Our revisions of these formerly "traditional" lecture courses have included in-class case studies with and without peer facilitators and peer-facilitated small-group workshops. Based on analyses…

Using a variety of visualization tools for teaching and learning science and chemistry is necessary because pupils better understand chemical phenomena and formulate appropriate mental models. The purpose of the presented study was to determine the importance of a virtual laboratory as a visualization element when addressing chemical contents…

This study used a Chinese-language version of the Index of Science Reading Awareness to explore the science reading metacognition and comprehension of Taiwanese students. Structural equation modelling results confirmed the underlying model comprised three clusters of metacognitive knowledge: beliefs and confidence in science reading, knowledge of…

Expanded learning time (ELT) refers to a longer school day, week, or year. ELT schools are becoming common in the United States and aim to provide all students with additional opportunities for learning, recreation, and enrichment. ELT schools differ from afterschool programs that take place immediately following the regular school day and serve a…

The aim of the present article is to point out the problematic issue of administrating PISA science literacy exam to the ultra-orthodox schools in Israel. It has been assumed that some texts included in the test may offend the feelings of the ultra-orthodox population or may contradict Orthodox upbringing and therefore constitute a cultural bias.

This paper reports on an analysis of student conceptions in responses to explanation-type questions in a grade 12 (17-18 years) South African national physics examination. We were guided in our analysis of 921 examination scripts by a framework developed by Dagher and Cossman on types of explanations in science which enabled us to understand the…
