An important feature of the Math and Science Partnership (MSP) Program of the National Science Foundation is to increase K-12 student achievement in math and science by increasing the quality, quantity, and diversity of the nation's K-12 math and science teachers. Because the underlying supply of math and science teachers is never directly observed, the central premise of this article is that an examination of the extent to which the MSP Program might impact the quantity and quality of math and science teachers requires careful thought and modeling.

With that starting point, this study first develops a model that supports a premise that shifts in underlying supply can be inferred from shifts in the percentage of certified math teachers employed when (a) salaries are constrained to be below market clearing salaries and (b) uncertified or “out-of-field” certified teachers can compete as substitutes for certified math teachers. The study then tests the plausibility of the model using data from Texas and in so doing provides preliminary estimates of the extent to which a school or school district's MSP participation affected the supply of certified math teaches available to that school or district. The results, although inconclusive on the question of the labor supply effects of MSP participation by a school or school district, do suggest the reasonableness of the model for future work when more appropriate data will be available.  相似文献

Abstract

High school underrepresented minority students in the US are at an increased risk of dropping out of the STEM pipeline. Based on expectancy-value theory, we examined if Latino students’ perception of support from parents, siblings/cousins, teachers, and friends in 10th grade predicted their science ability self-concepts and values, which in turn predicted their classroom engagement. Survey data were collected from 104 Latino high school students and their science teachers. The findings suggest that adolescents’ perceptions of overall support and home-based support predicted adolescents’ science ability self-concepts at 10th grade while controlling for their 9th grade self-concepts. Although adolescents reported high support from teachers, teacher or school-based support alone was not a strong correlate of their motivational beliefs. Perceived support was indirectly related to classroom engagement through adolescents’ ability self-concepts. Feeling supported across home and school may be necessary to sustain adolescents’ science motivational beliefs and, in turn, their science classroom engagement.  相似文献

In a technologically driven society, math and science students in the United States are falling further and further behind their international counterparts, resulting in an influx of STEM focused, reformed K-12 schools, including schools focused on project-based learning (PBL). This article reports a study of the effectiveness of PBL on high school students' performance on state mandated standardized mathematics and science achievement measures. Manor New Tech High School is a nationally recognized model STEM school, with a diverse student population, where all instruction is delivered through PBL. Although there is ample research suggesting that PBL is advantageous for increasing STEM learning compared to conventional teaching approaches, there is a lack of studies randomly assigning students to receive PBL. Further, some of the effects observed for students attending project-based schools could be due to a self-selection bias for students or parents that choose such an alternative learning environment. This study addresses both of these concerns and found that students taught through PBL, as a group, matched performance of conventionally taught students on all science 11th grade and mathematics 9th, 10th, and 11th grade TAKS achievement measures and exceeded performance by a scale score increase of 133 for the 10th grade science TAKS measure by (B = 133.082, t = 3.102, p < .05). One possible explanation of the differences observed in this study could be the TAKS instrument used to capture student math and science achievement that interprets “real-life applications” of content differently between math and science questions. These results align with literature on the effects of PBL and deepen our understanding of these effects by providing a controlled study with random assignments to the PBL experience. Future research looking at the effect of PBL on achievement on the PISA could be beneficial in identifying benefits of PBL implementation in schools.  相似文献

The purpose of this study was to collect and analyze data on sexual differences in secondary school students' attitudes towards science. Attitudinal differences were also analyzed for the independent variables of science programs and grade levels. Data were collected from 988 students using a modified version of the Fennema-Sherman Mathematics Attitude Scales to represent attitudes toward science. Reliabilities of the modified science subscales were all high ( > 0.83). Multivariate analysis of variance (MANOVA) was used to analyze the data for the main and interaction effects of the independent variables of sex (male, female), grade level (10th, 11th, 12th), and science program (advanced placement, academic, general, terminal). Significant differences (p < 0.05) were indicated for all main effects (sex, grade, science program). Interaction effects were not found. Mean separations for the various levels of sex, grade, and science program were performed for all attitudinal subscales. Females evidenced a significantly more positive attitude (p ? 0.01) than males on three subscales: Attitude Toward Success in Science Scale, Science as a Male Domain Scale, and Teacher Scale. Although not significant, males evidenced more positive attitudes on all the remaining five subscales. Eleventh graders evidenced significantly more positive attitudes than tenth graders on all but the Effectance Motivation Scale. Students in 11th grade had more positive attitudes than 12th-grade students on all scales but Science as a Male Domain Scale; however, these differences were not significant. Tenth graders differed significantly from 12th graders on three subscales; Science Usefulness Scale, Confidence in Learning Science Scale, and Teacher Scale. Positive attitudes decreased from advanced placement to terminal programs. Academic students did not differ significantly from general students except on the Father Scale; however, they were significantly different (more positive) from the terminal students for all subscales. General students were also significantly different from terminal students except on the three subscales of Attitudes Toward Success in Science, Science as a Male Domain, and Effectance Motivation.  相似文献

In light of the perceived national need for more science and math teachers, this study was conceived to:
  • 1. Identify “teaching oriented” students among freshmen at a mid-western engineering school, who have chosen NOT to become teachers;
  • 2. Find out what reasons these “potential” science and math teachers have for deciding not to pursue teaching careers;
  • 3. Determine what amelioration of these problems would be necessary for them to no longer be factors which would inhibit students from becoming teachers.
Of a random sample of 110 students drawn from a freshman class, 98 participated fully in the study. Each participant took Holland's Self-Directed Search to determine “teaching orientation” and author-constructed instruments to assess their concerns about teaching. Results showed “teaching oriented” students avoided teaching due to low starting salaries, lack of job security, low maximum salaries, not wanting to do the work teacher's do, poor job availability and discouragement by family and friends. Starting salaries of $21,693 and salaries of $32,600 for a teacher with a B.A. and 10 years experience were among the changes deemed necessary to make teaching attractive.  相似文献

A survey instrument was developed and administered to 1,222 K-12 mathematics and science teachers to measure their beliefs about and use of inquiry in the classroom. Four variables (grade level taught, content area taught, level of support received, and self-efficacy for teaching inquiry) were significantly correlated to two dependent variables, percentage of time that students are engaged in inquiry during a typical lesson and the perceived ideal percentage of instructional time that should be devoted to inquiry. Specifically, elementary school teachers reported using inquiry-based practices more than either middle-school or high-school teachers; similarly, elementary-school teachers believed such practices should be used more often. All groups, however, reported believing in an ideal percentage of time devoted to inquiry instruction that was significantly greater than their reported percentage of time actually spent on inquiry instruction. A disordinal effect was found between grade level taught and content area taught; at the elementary level, science teachers reported both an ideal and actual percentage of time on inquiry higher than those reported by the math teachers, while at the high school level math teachers reported both an ideal and actual percentage of time on inquiry higher than those reported by the science teachers. No correlations were found between typical and ideal percentage of time devoted to inquiry and subject matter content knowledge training, gender, years of teaching experience, or maximum degree earned.  相似文献

Similar results from four studies dealing with third, seventh, and eleventh grade students and their views of science teachers, science classes, usefulness of science study, and what it is like to be a scientist are reviewed and analyzed. The studies include the affective data from the 1977 NAEP report, the 1982 NAEP information, an Iowa follow-up study, and a study limited to one large school district. The analysis permits a synthesis of information on the failures of school science to affect student perceptions positively. Relatively few areas are identified which illustrate positive effects of science programs on students. Primary problems identified are: (1) science is less fun and exciting the longer students stay in school; (2) teachers are viewed as providers of information; the more preparation a teacher has and the more advanced the class, the less likely is a teacher ever to admit not knowing; (3) students do not feel more successful and/or more curious as they progress through a science program; (4) the school program does not provide increasingly accurate information and/or encouragement for science career choices.  相似文献

By applying the self-to-prototype matching theory to students?? academic choices, this study links the unpopularity of science in many industrialized countries with the perceived gap between typical persons representing science (e.g. physics teachers) on the one hand and students?? self-image on the other. A sample of N?=?308 Dutch and German students described both themselves and typical teachers representing different school subjects using 65 trait adjectives. The following hypotheses were tested: The typical hard sciences teacher and the typical languages teacher will be perceived as differing in their personal characteristics. The typical physics teachers will be perceived as being less similar to students' own self-image than teachers representing languages. Actual choices students make during secondary school should correlate with the perceived fit between students?? self-image and the prototype of teachers representing different school subjects, especially in the less frequent and less popular choices of a math or physics major/profile. The findings supported these hypotheses. The discussion stresses that students acquire not only knowledge about science but also about science culture (sensu Aikenhead) in their science classes and that students?? image of science teachers can influence their academic choices.  相似文献

This study examines the long-term effects of a home visiting program, Home Instruction for Parents of Preschool Youngsters, on students from mostly low-income, Latino families (n = 254). Children who were in the home visiting program during their early years were compared with a similar demographic group who participated in prekindergarten in the same inner-city area but did not participate in home visiting. Data linked participation in home visiting to state test scores and other information from public schools through the end of elementary school. Research Findings: Secondary data analyses tested for intervention effects on reading and math achievement in an urban school district using 4 waves of data covering kindergarten through 5th grade. Growth curve modeling showed that participation in home visiting predicted higher academic achievement through the 5th grade. Practice or Policy: Parent-focused intervention during early childhood appears to have a lasting impact on children’s achievement. In addition to parent engagement, quality school curriculum and quality instruction affect achievement in elementary school. A comprehensive curriculum focus throughout the early school years should be implemented regardless of preparation for high-stakes testing.  相似文献

We investigated whether teachers’ judgments of students’ aptitude had reciprocal effects on students’ motivation and math grades. We expected that teachers’ judgments of students’ aptitude would predict students’ grades and motivation, and that teachers’ judgments would also be predicted by these two aspects. A sample of N = 519 elementary school students was investigated at four measurement occasions from the end of third until the end of fourth grade. Students reported their self-concepts and intrinsic task values in math. Teachers (N = 27) judged students’ aptitude in math and provided students’ math grades. Cross-lagged panel analyses revealed that students’ prior grades and prior self-concepts (but not intrinsic task values) had positive effects on teachers’ subsequent judgments of student aptitude. Also, teachers’ prior judgments of student aptitude predicted students’ subsequent grades but not motivation. The findings underscore the importance of teachers’ judgments for students’ achievement development and give insights into which students’ motivational variables influence teachers’ perceptions of students’ aptitude.  相似文献

We investigate the relationship between teacher licensure test scores and student test achievement and high school course-taking. We focus on three subject/grade combinations—middle school math, ninth-grade algebra and geometry, and ninth-grade biology—and find evidence that a teacher's basic skills test scores are modestly predictive of student achievement in middle school math and highly predictive of student achievement in high school biology. A teacher's subject-specific licensure test scores are a consistent and statistically significant predictor of student achievement only in high school biology. Finally, we find little evidence that students assigned to middle school teachers with higher basic-skills test scores are more likely to take advanced math and science courses in high school.  相似文献

A challenge facing many schools, especially those in urban settings that serve culturally and linguistically diverse populations, is a disconnection between schools and students' home communities, which can have both cognitive and affective implications for students. In this article we explore a form of “connected science,” in which real‐world problems and school‐community partnerships are used as contextual scaffolds for bridging students' community‐based knowledge and school‐based knowledge, as a way to provide all students opportunities for meaningful and intellectually challenging science learning. The potential of these scaffolds for connected science is examined through a case study in which a team of fifth‐grade teachers used the student‐identified problem of pollution along a nearby river as an interdisciplinary anchor for teaching science, math, language arts, and civics. Our analysis makes visible how diverse forms of knowledge were able to support project activities, examines the consequences for student learning, and identifies the features of real‐world problems and school–community partnerships that created these bridging opportunities. © 2001 John Wiley & Sons, Inc.

In response to international concerns about scientific literacy and students’ waning interest in school science, this study investigated the effects of a science‐writing project about the socioscientific issue (SSI) of biosecurity on the development of students’ scientific literacy. Students generated two BioStories each that merged scientific information with the narrative storylines in the project. The study was conducted in two phases. In the exploratory phase, a qualitative case study of a sixth‐grade class involving classroom observations and interviews informed the design of the second, confirmatory phase of the study, which was conducted at a different school. This phase involved a mixed methods approach featuring a quasi‐experimental design with two classes of Australian middle school students (i.e., sixth grade, 11 years of age, n = 55). The results support the argument that writing the sequence of stories helped the students become more familiar with biosecurity issues, develop a deeper understanding of related biological concepts, and improve their interest in science. On the basis of these findings, teachers should be encouraged to engage their students in the practice of writing about SSI in a way that integrates scientific information into narrative storylines. Extending the practice to older students and exploring additional issues related to writing about SSI are recommended for further research.  相似文献

The present study examined reciprocal influences between student–teacher relationship quality and students’ externalizing and internalizing behaviors in secondary education. Our sample included 1,219 secondary school students (49.1% boys; Mage = 13.53, SD = 1.77) from seventh, eighth, tenth, and eleventh grade. Students reported about their externalizing and internalizing behaviors and the quality of the relationships (closeness, conflict) with their Dutch and math teachers at three occasions within one school year. Cross-lagged path models showed positive reciprocal associations between conflict with the math teacher and externalizing behavior over time. For the Dutch teacher, externalizing behavior positively predicted conflict over time, but not the other way around. Externalizing behavior also negatively predicted closeness with both teachers over time.  相似文献

This study was designed to examine benefits and challenges of teaching through videoconferencing in the context of students’ field placement experiences, particularly as it relates to an inquiry-based approach to teaching and learning math and science. In the context of mathematics and science methods courses, preservice teachers, with the supervision of professors, field placement supervisors and cooperating teachers, taught a series of math and science lessons via video conferencing to 5th grade classes in a major urban public school. Two major results of this study indicate that: (1) teaching through videoconferencing highlights strengths and weaknesses in questioning skill techniques that are at the heart of an inquiry-based approach; (2) teaching through videoconferencing raises the intellectual challenge of teaching and allows preservice teachers to look face to face into their limited understanding of the content matter in math and science.  相似文献

Abstract

This exploratory study aimed to describe the impact of the ‘Science in Family project’, as a transformative learning model for science teachers trying to improve student’s attitudes toward STEM subjects. This study took place in a public elementary school in Monterrey, Mexico, which has been developing this project for more than thirteen years with students from 4th, 5th and 6th grade. We used participant observation and interviews with four families whose children are students of this elementary school, and with one family whose sons were students of this school some years ago. Results showed that there is a relationship between positive attitudes towards science in students who were exposed to transformative learning models of teaching. Two of the participants took steps to follow science related careers. This study helps to illuminate the extent to which teacher education models influence students’ attitudes and how positive attitudes to science are influenced by the use of learning by doing projects.  相似文献

ABSTRACT

We study the effectiveness of teachers certified by the National Board for Professional Teaching Standards (NBPTS) in Washington State, which has one of the largest populations of National Board-Certified Teachers (NBCTs) in the nation. Based on value-added models in math and reading, we find that NBPTS-certified teachers are about 0.01–0.05 student standard deviations more effective than non-NBCTS with similar levels of experience. Certification effects vary by subject, grade level, and certification type, with greater effects for middle school math certificates. We find mixed evidence that teachers who pass the assessment are more effective than those who fail, but that the underlying NBPTS assessment score predicts student achievement.  相似文献

It is well known that teachers frequently observe a decline in the scholastic motivation of many adolescent students, which in turn is often associated with a decline in students’ individual school self-concept. In contrast, less is known about the association between students’ individual school self-concept and school engagement, or the related concepts of school belonging and helplessness in school. The current study explored social relationships as mediators in the association between individual school self-concept and adolescents’ school engagement, belonging to school and helplessness in school in a large sample of 7th and 8th grade students (N?=?1088; MAge?=?13.7) in secondary schools in Brandenburg, Germany. The results of two structural equation models showed that the teacher–student relationship mediated the association between individual school self-concept and school engagement, belonging to school and helplessness in school, respectively. In contrast, the student–student relationship did not mediate any of these associations.  相似文献

The study examines science-related course choices of high-school students in the culturally diverse schools of the province of British Columbia, Canada. The analysis employs K-12 provincial data and includes over 44,000 students born in 1990 who graduated from high school by 2009. The research sample reflects the presence of about 27% of students for whom English is not a first language. We construct an empirical model that examines ethno-linguistic and gender differences in Grade 12 course choices while accounting for personal and situational differences among students. The study employs a course selection typology that emphasizes readiness for science, technology, engineering and math fields of study. Findings indicate that math- and science-related course selection patterns are strongly associated with ethnicity, qualified not only by gender and prior math and science achievement but also by the individual's grade level at entry to the system and enrollment in English as a Second Language program. Students who are more likely to engage in math and science courses belong to Asian ethno-linguistic groups and entered the provincial school system during the senior high-school years. We suggest that ethnic diversity and broader academic exposure may play a crucial role in changing the gender composition of science classrooms, university fields of study and science-related occupations.  相似文献
