What drives US competitiveness in mathematics and science?

The Trends in International Mathematics and Science Study (TIMSS) shows that US school students have a lower level of achievement than students from many East Asian countries. Therefore, media, researchers and policy‐makers in the United States have often argued that US competitiveness in mathematics and science will decline. This paper aims at verifying this conclusion by analysing data on medallists at the International Olympiads for high school students. The analysis suggests that US competitiveness may not be endangered.     

Who succeeds in STEM studies? An analysis of Binghamton University undergraduate students

Using student level data, the characteristics of STEM and Non-STEM students are examined for attributes associated with academic success. We use fixed effects models to analyze the variables’ role in attaining graduation and college GPA and find preparation and ability, as evidenced by Advanced Placement course work, mathematical ability, gender, ethnicity, high school GPA and college experience are all statistically significant indicators of success. These attributes may confer a comparative advantage to STEM students. The engineers have statistically significant differing response elasticities than the non-engineers, and show evidence of persistence that may arise from learning-by-doing. A successful engineering STEM major at Binghamton has good mathematics preparation, and disproportionately is of Asian ethnicity. Women are few in numbers as engineers. Other STEM fields see less emphasis on mathematics preparation, but more emphasis on the presence of AP course work. Women have the same presence in these other STEM fields as in the whole university.     

Who teaches mathematics content courses for prospective elementary teachers in the USA? Results of a second national survey

This article reports on a second national survey of higher education institutions in the USA to answer the question “Who teaches mathematics content courses for prospective elementary teachers, and what are these instructors’ academic and teaching backgrounds?” and addresses valuable information not collected with the first survey conducted in 2010. We surveyed 1740 institutions and a faculty member from each of 413 institutions (23.7%) participated in the survey. The survey results demonstrate that the majority of these institutions are not meeting the recommendations of the Conference Board of Mathematical Sciences (2012) and the Association of Mathematics Teacher Educators (2017) for prospective elementary teachers to take at least 12 semester-hour credits of mathematics content designed specifically for them. The data do indicate that there is movement toward more activity-based approaches for these courses as compared to the 2010 survey. Additionally, there is an increase in these courses having instructors with doctorates in mathematics education as well as an increase in instructors having grades 7–12 teaching experience. Most instructors for these courses do not have elementary teaching experience and have likely not had opportunities to think deeply about the important ideas in elementary mathematics. While most institutions still do not provide training and/or support for these instructors, formalized support and training appear to be increasing since the 2010 survey.

     

Who teaches mathematics content courses for prospective elementary teachers in the United States? Results of a national survey

This article reports on a national survey of higher education institutions in the United States to answer the question, “Who teaches mathematics content courses for prospective elementary teachers, and what are these instructors’ academic and teaching backgrounds?” We surveyed 1,926 institutions, and a faculty member from each of 825 institutions (42.8?%) participated in the survey. The survey results demonstrate that the majority of institutions are not meeting the recommendations of the Conference Board of the Mathematical Sciences (The mathematical education of teachers. American Mathematical Society, Providence, RI, 2001), the National Council of Teachers of Mathematics (Professional standards for teaching mathematics. National Council of Teachers of Mathematics, Reston, VA, 2005), and the National Council on Teacher Quality (Greenberg and Walsh 2008) for prospective elementary teachers to take at least nine credits of mathematics content designed specifically for them. Additionally, most instructors for these courses do not have elementary teaching experience and have likely not had opportunities to think deeply about the important ideas in elementary mathematics, and most institutions do not provide training and/or support for these instructors.     

Representational and decorative pictures in science and mathematics tests: Do they make a difference?

Multimedia effects in learning receive much attention in research. In contrast, effects of different picture types in testing materials are hardly studied. The present computer-based experiment with n = 404 students investigates the effects of adding a representational picture (RP) or a decorative picture (DP) to text-based educational test items on students' performance, metacognition, test-taking motivation and item processing in the domains of science and mathematics. The data show that RPs enhanced students' performance, perception of ease and test-taking pleasure in both scientific and mathematics items. Furthermore, RPs increased time on task (TOT) in mathematics, but not in scientific items. DPs had no significant effect on students’ performance, test-taking pleasure or perceived ease, while DPs reduced TOT in mathematics items. Explanations for the process-related differences are discussed. The pattern of results indicates that the multimedia principle and the coherence principle from instructional psychology can be transferred to educational testing material.     

Raising awareness of uncertainty: A useful addendum to courses in the history and philosophy of science for science teachers?

A brief consideration of the need for courses in the history and philosophy of science (HPS) for science teachers is followed by the development of a suggested addendum. The rationale accepts the developmental argument that a conscious awareness of personal uncertainty of explanation provides the motor of change needed to involve science teachers in thinking critically about the nature of their subject. Following the technique pioneered in a different context by Acredolo and O'Connor (1991), the addendum is developed as a test procedure fostering the expression of uncertainties in relation to important questions about science. Using questions designed to serve our specific purposes, a form of the test is trialled on a small group of science teachers attending courses in a Graduate Certificate in Science Education, and the results used to stimulate and promote their discussion of some critical matters concerning the nature of science.     

Crosscutting concepts and achievement: Is a sense of size and scale related to achievement in science and mathematics?

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.     

Online learning: Is it meant for science courses?

The authors discuss a case study experience in conducting scientific courses such as Environmental Chemistry and Spectroscopy to different groups of undergraduates at Universiti Malaysia Sarawak (UNIMAS), using web-based learning environments to support conventional teaching/learning sessions. The authors discovered that by supplementing the learning online, students became more interested in their respective fields of study, and thus were able to participate in class discussions more freely. Online, a higher number of group activities can be organized to consolidate the learning of specific topics. The web-based learning environment also allows more interaction opportunities between peers and with the course instructor. Overall, the students reported they found that learning online made the course more interesting, and that the students were consciously aware that they learned more in the process. The paper also highlights the major benefits of conducting a course online from a course instructor's perspective.     

The national in‐service courses for science teachers and their effect on educational reform in Mexico

The educational system in Mexico has undergone important changes in recent decades. One of the most important took place in 1993, when the compulsory character of secondary school (ages 12–15) was established. National In‐service Courses (NICs) were established as a way to bring curricular changes proposed in the reform near to the teachers. The results, according to the National Certification Exams, have not been satisfactory. In this paper, we describe the general context of education in Mexico, putting emphasis on teacher initial preparation and the reform that took place as well as the way in‐service courses are implemented, analyzing their possibilities to bring about real changes in science teaching and learning.     

Sources of students’ frustration in pre-university level, prerequisite mathematics courses

This paper looks at sources of frustration in students of “prerequisite” mathematics courses (PMC), that is, courses required for admission into undergraduate programs in a large, urban, North American university. The research was based on responses to a questionnaire addressed to students and interviews with students and instructors. In the design of the questionnaire and the analysis of responses, an “institutional” theoretical perspective was taken, where frustration was conceived not only as a psychological process but also as a situation experienced by participants in a concrete educational institution. Several sources of frustration were identified as important in the group of respondents: the fast pace of the courses, inefficient learning strategies, the need to change previously acquired ways of thinking, difficult rapport with truth and reasoning in mathematics, being forced to take PMC, insufficient academic and moral support on the part of teachers, and poor achievement. These sources of frustration are discussed from the point of view of their impact on the quality of the mathematical knowledge that students develop in the PMC. Consideration is also given to the possibilities of improving the quality of this knowledge, given the institutional constraints implicated in the sources of students’ frustration.

Women planning to major in computer science: Who are they and what makes them unique?

Despite the current growing popularity of the computer science (CS) major, women remain sorely underrepresented in the field, continuing to earn only 18% of bachelor’s degrees. Understanding women’s low rates of participation in CS is important given that the demand for individuals with CS training has grown sharply in recent years. Attracting and retaining more women to high-paying fields like CS may also help narrow the gender pay gap. Further, it is important that women participate in developing new technology so that technology advances serve the needs of both women and men. This paper explores the background characteristics, career aspirations, and self-perceptions of 1636 female first-year college students in the United States who intend to major in CS and compares them with 4402 male CS aspirants as well as with 26,642 women planning to major in other STEM sub-fields. The findings reveal a unique profile of women who pursue the CS major and notes many significant differences between men and women in CS and between women in CS and those in other STEM fields. For instance, women in CS tend to earn lower high school grades than women in other STEM fields, but earn higher SAT verbal scores. They also rate themselves higher than men in CS and women in other STEM fields on measures of their artistic ability, but rate themselves lower on other self-ratings, including academic and leadership ability. Further, women in CS are more likely to be undecided in their career plans than men in CS and women in other STEM fields. Understanding the unique characteristics of women in CS will help inform policies and recruitment programs designed to address the gender gap in computing.     

Identity and biography as mediators of science and mathematics faculty’s involvement in K-12 service

This article explores aspects of science and mathematics faculty identities and biographies that mediated their involvement in K-12 service. Faculty expressed five motivations for participating in K-12 service—advancing their research agenda, advocating environmental consciousness, desiring to be involved in their children’s schools, aspiring to improve their pedagogical practices and promoting equity and social justice.     

Using valsiner’s zone theory to interpret Teaching practices in mathematics and science Classrooms

This study explores the use of Valsiners zone theory as a way to interpret the zones of proximal development of three secondary teachers in mathematics and science. Specifically, we used classroom discourse to identify what the participating teachers promoted (zone of promoted action) or allowed (zone of free movement) in the classroom as a way to understand better their potential for development. We found that teachers who promoted actions or events that they ultimately did not allow students to experience seemed to be at a point in their development analogous to Vygotskys pseudo-conceptual stage, prior to full concept formation. Moreover, we found that, at this illusionary zone, the teachers capacity to listen actively to students thinking seemed to affect the teachers transition toward more inquiry-based forms of practice. We concluded that understanding the zone of promoted action and the zone of free movement the teacher organizes in the classroom can indicate the existence or absence of an illusionary zone and thereby provide insight into a teachers potential for development.     

Identity: a complex structure for researching students’ academic behavior in science and mathematics

This article is a response to Pike and Dunne’s research. The focus of their analysis is on reflections of studying science post-16. Pike and Dunne draw attention to under enrollments in science, technology, engineering, and mathematics (STEM) fields, in particular, in the field of physics, chemistry and biology in the United Kingdom. We provide an analysis of how the authors conceptualize the problem of scientific career choices, the theoretical framework through which they study the problem, and the methodology they use to collect and analyze data. In addition, we examine the perspective they provide in light of new developments in the field of students’ attitudes towards science and mathematics. More precisely, we draw attention to and explicate the authors’ use of identity from the perspective of emerging theories that explore the relationships between the learner and culture in the context of science and mathematics.     

Provision of in-service training of mathematics and science teachers in Botswana: teachers’ perspectives

Teaching is a field that is dynamic, with innovations necessitating upgrading of skills and education of teachers for the successful implementation of reforms. The behaviour and attitudes of teachers towards teaching and learning and their knowledge banks are the result of the impact of in-service training. This study investigated the perceptions of mathematics and science teachers in Botswana towards in-service provision by the Department of Mathematics and Science Education In-service Training unit (DMSE-INSET), whose mandate is to improve the quality of teaching by supporting teachers through training programmes that enable them to take ownership of their professional development. Data were collected from a sample of 42 senior Mathematics and Science secondary school teachers, using structured interviews with open-ended questions, which were analyzed qualitatively. The findings show that teachers’ concerns included the lack of impact of current in-service training programmes on the education system, no regular follow-up activities to support the one-off workshops and insufficient skills acquired to sustain the implementation of the strategies solicited by the workshops.     

Who is granted authority in the mathematics classroom? An analysis of the observed and perceived distribution of authority

The article deals with the way in which authority was established and interpreted by teachers and students in two Flemish sixth-grade mathematics classrooms. Problem-solving lessons during a seven-month observation period were analysed regarding three aspects of teacher–student interactions that explicitly or implicitly reflect who bears mathematical authority: (1) to whom were students allowed to ask for help; (2) who was allowed to answer students’ mathematics-related questions; and (3) who was allowed to evaluate students’ responses. For each of these aspects, we were interested whether authority was ascribed only to the teacher or whether authority was distributed more broadly, with students being considered accountable for their own and other’s learning process. Interviews with teachers and students were conducted to investigate the meaning that participants gave to the practices in which they were involved.     

Gender differences in mathematics and science: the role of the actiotope in determining individuals’ achievements and confidence in their own abilities

Despite changes, gender differences in math and science continue to exist in some countries. We examined whether the actiotopes of boys and girls at the high school level in math and science differed and the extent to which (a) their actiotope components, (b) the progressive development of their actiotopes (dynamic perspective), and (c) the co-adaptation of their actiotopes (systems perspective) function as predictors for girls’ and boys’ achievements and confidence in one’s own abilities in math and science. To answer these questions, we examined girls and boys (N?=?361) in Canada, the Czech Republic, and Germany with a questionnaire. The results suggest that girls are less effective at progressively developing their actiotopes in the fields of math and science and that modifications in their actiotopes were less well balanced by stabilizing forces. Independent of gender, the actiotope aspects considered here are suited to predicting achievements and confidence in one’s own abilities in math and science.     

South Africa’s readiness to integrate ICT into mathematics and science pedagogy in secondary schools

One of South Africa’s identified priorities is the implementation of ICT in education. To this end a phased implementation plan was initiated in 2004 for ICT to be implemented into schools across the country over eight years. During this time South Africa also participated in three international studies undertaken by the International Association for the Evaluation of Educational Achievement (IEA) focusing on ICT in Education. Each of these permitted the country to benchmark its progress in terms of other countries and their implementation of ICT in education. The latest study, SITES 2006 provides a useful set of indicators against which South Africa can evaluate its progress with regard to its implementation of ICT. This paper seeks to evaluate South Africa’s readiness to integrate ICT into mathematics and science classrooms. This was done using a number of indicators of “sustainable change” derived from SITES 2006 and then comparing these to countries such as Chile, Thailand and Norway, the former two with similar context and conditions and the latter with contrasting conditions. The findings reveal that whilst South Africa has made some progress since 1998 in terms of the implementation of ICT in education, that the majority of schools are still in their infancy regarding the acquisition of ICT and most of those who have access are still in the process of trying to integrate the ICT into their teaching and learning. It would appear that more fundamental needs in South Africa’s education system have dominated its priorities.     

Getting started: exploring pre-service teachers’ confidence and knowledge of culturally responsive pedagogy in teaching mathematics and science

Recent changes to the Australian Curriculum reinforce the need for all educators to value the cultures and perspectives of Aboriginal and Torres Strait Islander students. The disproportionately high levels of educational disadvantage experienced by many of these students has prompted the Australian Institute for Teaching and School Leadership to introduce two teacher standards aimed at improving awareness of Aboriginal and Torres Strait Islander cultures and histories, and enactment of pedagogies that support Aboriginal and Torres Strait Islander student learning. We describe a pilot study focussed on one cohort of final year mathematics and science primary/middle pre-service teachers (PSTs) as they navigate these standards. We explore PSTs’ self-reported knowledge and confidence before and after targeted interventions designed to cultivate cultural responsiveness. Although the findings suggest an increase in PSTs’ perceived confidence, further work is needed towards what could be considered culturally responsive pedagogies for early career mathematics and science teachers.
