This study examined the degree to which individual differences in students' (N = 232) concepts of size and scale are explained by factors such as students' innate sense of number, out‐of‐school science experiences, exposure to size and scale instruction, gender identities, and racial/ethnic identities. There is increasing emphasis being placed on the use of crosscutting concepts to promote deep learning in science. A multiple linear regression indicated students' racial/ethnic identities, experiences with scale outside of school, and exposure to size and scale instruction significantly added to the prediction model. Results from this study can both inform the movement toward incorporating crosscutting concepts into pedagogy as well as inform educators, administrators, and other stakeholders of the factors that may shape students' understanding of the cross‐cutting concept of scale, proportion, and quantity.  相似文献

ABSTRACT

Crosscutting concepts such as scale, proportion, and quantity are recognised by U.S. science standards as a potential vehicle for students to integrate their scientific and mathematical knowledge; yet, U.S. students and adults trail their international peers in scale and measurement estimation. Culturally based knowledge of scale such as measurement units may be built on evolutionarily-based systems of number such as the approximate number system (ANS), which processes approximate representations of numerical magnitude. ANS is related to mathematical achievement in pre-school and early elementary students, but there is little research on ANS among older students or in science-related areas such as scale. Here, we investigate the relationship between ANS precision in public school U.S. seventh graders and their accuracy estimating the length of standard units of measurement in SI and U.S. customary units. We also explored the relationship between ANS and science and mathematics achievement. Accuracy estimating the metre was positively and significantly related to ANS precision. Mathematics achievement, science achievement, and accuracy estimating other units were not significantly related to ANS. We thus suggest that ANS precision may be related to mathematics understanding beyond arithmetic, beyond the early school years, and to the crosscutting concepts of scale, proportion, and quantity.  相似文献

ABSTRACT

Although there has been some success with programmes that aim to increase STEM involvement by women and underserved minorities, science educators continue to seek ways to promote students’ interest in STEM. This study builds on social cognitive career theory (SCCT) and the theory of enclothed cognition to assess the impact of wearing lab coats on 5th-grade students. Students were assigned to a treatment group (that wore lab coats, n = 106) or a control group (that did not wear lab coats, n = 110) for 10 science classes taught by their classroom science teacher. Students were assessed pre and post to the intervention with a survey designed to measure science interest, recognition from others as a science person, science self-efficacy, and STEM career goals. Results showed students’ interest in science was not significantly changed due to wearing the lab coat, but the lab coats did have significant effects on students’ perceived recognition by others as being a science learner. Furthermore, those treatment students with low self-efficacy (compared to those with high self-efficacy) and those with who did not report having access to a parent with a STEM career had significant increases in perceptions of self-efficacy in science.  相似文献

This study examined the relationship between students' (N = 229) concepts of size and scale and students' achievement in science and mathematics over a 3-year period. Size and scale are considered one of the big ideas in science that permeates disparate science and mathematics content areas, yet little is known about the relationship between students' conceptualization of size and scale and students' achievement in science and mathematics. The study used a modified panel longitudinal design to follow the same class of students over a 3-year period. The goal was to explore whether understandings of size and scale are related to achievement in mathematics and science. Results indicated a strong positive significant relationship existed between students' understanding of size and scale and students' science achievement in grades 5 and 8. There was a positive significant relationship between students' concepts of size and scale and students' mathematics achievement in grades 5, 6, 7, and 8. An examination of the relationships is included as well as a discussion of the integration of crosscutting concepts into science and mathematics instruction as a way to support deep learning.  相似文献
