Kim, Sangsoo; Park, Jongwon – International Journal of Science and Mathematics Education, 2018
Observing scientific events or objects is a complex process that occurs through the interaction between the observer's knowledge or expectations, the surrounding context, physiological features of the human senses, scientific inquiry processes, and the use of observational instruments. Scientific observation has various features specific to this…

Guerrero-Ortiz, Carolina; Mena-Lorca, Jaime; Soto, Astrid Morales – International Journal of Science and Mathematics Education, 2018
This study shows how, in the initial training of mathematics teachers, it is possible to promote processes of abstraction and mathematisation through modelling a real situation with the support of auxiliary material to mediate understanding. By adapting elements of the theoretical and methodological framework called Abstraction in Context (AiC),…

Garza, Tiberio; Huerta, Margarita; Spies, Tracy G.; Lara-Alecio, Rafael; Irby, Beverly J.; Tong, Fuhui – International Journal of Science and Mathematics Education, 2018
Academic language is critical for English learners (ELs) to succeed in the science classroom. This study analyzed the instructional practices centered around academic language taking place in eight, fifth-grade classrooms during a grant-funded project. Observational data collected through a classroom observation instrument were analyzed to…

Ding, Lin – International Journal of Science and Mathematics Education, 2018
This study examines progression trends of Chinese students' scientific reasoning skills across grade levels from elementary school to university. A large-scale survey using the Classroom Test of Scientific Reasoning (CTSR) was conducted with 2669 Chinese students at 13 grade levels (grades 4-16). The construct validity of the CTSR was first…

Nawani, Jigna; Kotzebue, Lena; Rixius, Julia; Graml, Michael; Neuhaus, Birgit J. – International Journal of Science and Mathematics Education, 2018
This study investigated the effects of teachers' use of "focus questions" on students' knowledge structures and classroom teaching-learning process by re-analyzing selected data from a quasi-experimental pre-post video study (Wadouh, 2007). Focus questions are content-related anchoring questions highlighting the key content taught in…

Dubovi, Ilana; Levy, Sharona T.; Dagan, Efrat – International Journal of Science and Mathematics Education, 2018
Proportional reasoning is the basis for most medication calculation processes and is fundamental for high-quality care and patient safety. We designed a simulated Medication Mathematics (siMMath) environment to support proportional reasoning in transitioning via concreteness fading between two mediators. The first mediator is simulated nursing…

Kim, Dong-Joong; Lim, Woong – International Journal of Science and Mathematics Education, 2018
This study compares English- and Korean-speaking university students' colloquial and mathematical discourses on the notion and practice of limit. There exists a lexical discontinuity in Korean with the word limit, since the mathematical word for limit is not commonly used as a colloquial word in Korean, unlike its use in English. This study…

Jacobson, Erik; Lobato, Joanne; Orrill, Chandra H. – International Journal of Science and Mathematics Education, 2018
Mathematics teacher education aims to improve teachers' use of mathematical knowledge to support teaching and learning, an aspect of pedagogical content knowledge (PCK). In this study, we interviewed teachers to understand how they used mathematics to make sense of student solutions to proportional reasoning problems. The larger purpose was to…

Tran, Dung; Tarr, James E. – International Journal of Science and Mathematics Education, 2018
Through the lenses of statistical investigations and cognitive demands, we examined bivariate data tasks offered in US high school mathematics textbook series--a popular representative of three curriculum types: traditional, integrated, and hybrid. We developed a framework grounded in literature of association topics for the inclusion and…

Lee, Silvia Wen-Yu – International Journal of Science and Mathematics Education, 2018
The purpose of this study was, first, to understand the item hierarchy regarding students' understanding of scientific models and modeling (USM). Secondly, this study investigated Taiwanese students' USM progression from 7th to 12th grade, and after participating in a model-based curriculum. The questionnaire items were developed based on 6…

Tsai, Chun-Yen; Huang, Tai-Chu – International Journal of Science and Mathematics Education, 2018
This study investigated the relationship between adult self-efficacy in science and scientific competencies of Taiwanese citizens. Probability proportional to size sampling was used to select 1830 participants between the ages of 18 and 70. The research methods employed was survey research; analysis was conducted using hierarchical regression…

Hu, Xiang; Leung, Frederick K. S.; Teng, Yuan – International Journal of Science and Mathematics Education, 2018
The results of international large-scale assessments have shown that countries vary considerably in their mathematics performance. Culture has been suggested as a possible cause for the national difference, but insufficient empirical research has been conducted to investigate the effect of culture on mathematics achievement. Based on Hofstede's…

Hwang, Jihyun; Choi, Kyong Mi; Bae, Yejun; Shin, Dong Hoon – International Journal of Science and Mathematics Education, 2018
Many efforts have been made to reach educational equity, especially to reduce mathematics and science achievement gaps by students' socioeconomic status. Across countries, educators strive to reform traditional teacher-centered instructional approaches to more student-centered/inquiry-based instruction to improve equity in education. In this…

Yao, Yiling; Kong, Qiping; Cai, Jinfa – International Journal of Science and Mathematics Education, 2018
Students in Shanghai ranked at the top in mathematics on the past two assessments of the Program for International Student Assessment (PISA). However, even though Asian students in general, and Chinese students in particular, ranked at the top in mathematics, we know little about Shanghai students' subjective well-being (SWB). This paper reports…
