Most studies of students' understanding of decimals have been conducted within Western cultural settings. The broad aim of the present research was to gain insight into Chinese Hong Kong grade 6 students' general performance on a variety of decimals tasks. More specifically, the study aimed to explore students' mathematical…

In this paper, we analyze the science activities offered at 7th grade in the Turkish science and technology curriculum along with addressing the curriculum's original intent. We refer to several science education researchers' ideas, including Chinn & Malhotra's (Science Education, 86:175--218, 2002) theoretical framework and…

This study presents a small part of a larger study investigating Turkish and German mathematics teachers' and their students' values (Values in Mathematics Teaching in Turkey and Germany). The main focus of the study was school levels of the teachers working at primary and secondary schools. The interactions related to nationality were…

This research study examined the effect of origami-based geometry instruction on spatial visualization, geometry achievement, and geometric reasoning of tenth-grade students in Turkey. The sample ("n" = 184) was chosen from a tenth-grade population of a public high school in Turkey. It was a quasi-experimental pretest/posttest design. A…

Algebra is the fundamental language of mathematics, and a profound understanding of school algebra is an important prerequisite for further studies in mathematical sciences. The aim of this study is to characterize the algebraic competence of the Norwegian upper secondary school students participating in Trends in International Mathematics and…

In recent decades, research has shown the challenge posed to teachers by science education in informal contexts such as science museums or centres. In addition, there is consensus that in the case of pupils visiting a science centre, learning improves when the visit is connected to the classroom curriculum, so the teachers' involvement in…

In this study, we developed an instrument for assessing teachers' mathematics content knowledge (MCK) on ratio and proportion and examined the profile of Indonesian primary teacher's MCK on this topic. The MCK items were administered to 271 Indonesian in-service primary teachers with a variety of educational backgrounds and teaching…

Knowledge structure is an important aspect for defining students' competency in biology learning, but how knowledge structure is influenced by the teaching process in naturalistic biology classroom settings has scarcely been empirically investigated. In this study, 49 biology lessons in the teaching unit "blood and circulatory…

The benefits of connecting school students with scientists are well documented. This paper reports how New Zealand teachers brought scientists into the classrooms through the use of videos of New Zealand scientists talking about themselves and their research. Two researchers observed lessons in 9 different classrooms in which 23 educational videos…

In 2001, the Chinese Ministry of Education issued Guidelines for Preschool Education (GPE) (trial version) to call on early childhood practitioners to use a child-centered and play-based approach to teaching and learning. The guidelines also include mathematics within the science domain and described its standards in a way that significantly…

The main purpose of this research was to investigate how Taiwanese grade 6 readers selected and used information from different print (main text, headings, captions) and visual elements (decorational, representational, interpretational) to comprehend a science text through tracking their eye movement behaviors. Six grade 6 students read a double…

School mathematics tends to have developed from the major cultures of Asia, the Mediterranean and Europe. However, indigenous cultures in particular may have distinctly different systematic ways of referring to space and thinking mathematically about spatial activity. Their approaches are based on the close link between the environment and…

Constructing explanations and participating in argumentative discourse are seen as essential practices of scientific inquiry. The objective of this study was to explore the elements and origins of pre-service secondary science teachers' alternative conceptions of tidal phenomena based on the elements used in Toulmin's Argument Model…

This paper investigates the factors that influence 15-year-old students' intentions to study physics post-16, when it is no longer compulsory. The analysis is based on the year 10 (age, 15 years) responses of 5,034 students from 137 England schools as learners of physics during the academic year 2008-2009. Factor analyses uncovered a range of…

This study explored learning competency based on the Indonesian National Examination focusing especially on chemistry performance and the circumstances of senior high school students and teachers in rural areas of Simeulue Island, Indonesia. The National Examination total score and chemistry score for students in rural areas were consistently…
