Student Motivation to Learn via Computer Conferencing 总被引：1，自引：0，他引：1
This study investigates why some university students appear motivated to learn via computer conferencing (CC) whereas others do not, exploring the correlations of three key aspects of student motivation—reasons for engaging in academic learning (goal orientation), beliefs that they can acquire the ability to use CC (self-efficacy), and beliefs that learning to use CC will help them learn the course material (outcome expectations)—with satisfaction and with the frequency of CC contributions. Participants (n = 79) came from 4 graduate-level face-to-face courses and 1 undergraduate DE course. The results suggest that students who believe that CC will help them learn the course material are more likely to express satisfaction and to be active online, that students who believe that they are capable of learning how to use CC are more likely to be active online, and that students who are concerned about their relative performance compared to others tend to send fewer messages to conferences where online activity is not graded. Practical implications for instructors and suggestions for future research are described. 相似文献

Many institutions of higher education confront seemingly unrelated needs of graduate students, who need not only to complete their dissertations but also to learn how to become proficient mentors for undergraduates as they move on to faculty roles. The graduate students are increasingly searching out high-impact learning experiences such as involvement with undergraduate research. The program we describe in this article offers a solution to these issues by pairing undergraduates with graduate students to work on their dissertation research. Undergraduates undertake hands-on research while learning about graduate school, and the graduate students learn about the mentoring process while receiving assistance that allows them to keep their dissertations moving toward completion. 相似文献

To increase participation of students of color in science graduate programs, research has focused on illuminating student experiences to inform ways to improve them. In biology, Black students are vastly underrepresented, and while religion has been shown to be a particularly important form of cultural wealth for Black students, Christianity is stigmatized in biology. Very few studies have explored the intersection of race/ethnicity and Christianity for Black students in biology where there is high documented tension between religion and science. Since graduate school is important for socialization and Black students are likely to experience stigmatization of their racial and religious identity, it is important to understand their experiences and how we might be able to improve them. Thus, we interviewed 13 Black Christian students enrolled in biology graduate programs and explored their experiences using the theoretical lens of stigmatized identities. Through thematic content analysis, we revealed that students negotiated experiences of cultural isolation, devaluation of intelligence, and acts of bias like other racially minoritized students in science. However, by examining these experiences at the intersection of race/ethnicity and religion, we shed light on interactions students have had with faculty and peers within the biology community that cultivated perceptions of mistrust, conflict, and stigma. Our study also revealed ways in which students' religious/spiritual capital has positively supported their navigation through biology graduate school. These results contribute to a deeper understanding of why Black Christian graduate students are more likely to leave or not pursue advanced degrees in biology with implications for research and practice that help facilitate their success. 相似文献

Background: Research has primarily concentrated on adults’ implicit theories about high quality science education for all students. Little work has considered the students’ perspective. This study investigated high school students’ implicit theories about what helped them learn science. Purpose: This study addressed (1) What characterizes high school students’ implicit theories of what facilitates their learning of science?; (2) With respect to students’ self-classifications as African American or European American and female or male, do differences exist in the students’ implicit theories? Sample, design and methods: Students in an urban high school located in south-eastern United States were surveyed in 2006 about their thoughts on what helps them learn science. To confirm or disconfirm any differences, data from two different samples were analyzed. Responses of 112 African American and 118 European American students and responses from 297 European American students comprised the data for sample one and two, respectively. Results: Seven categories emerged from the deductive and inductive analyses of data: personal responsibility, learning arrangements, interest and knowledge, communication, student mastery, environmental responsiveness, and instructional strategies. Instructional strategies captured 82% and 80% of the data from sample one and two, respectively; consequently, this category was further subjected to Mann-Whitney statistical analysis at p < .05 to ascertain ethnic differences. Significant differences did not exist for ethnicity but differences between females and males in sample one and sample two emerged. Conclusions: African American and European American students’ implicit theories about instructional strategies that facilitated their science learning did not significantly differ but female and male students’ implicit theories about instructional strategies that helped them learn science significantly differed. Because students attend and respond to what they think and perceive to be important, addressing students’ implicit theories may be one way to enhance science education reform. 相似文献

We present a review of an after-school program that has been running at Queensborough Community College of the City University of New York for the past 5 years. The program is unique among after-school activities for high school students in several ways. First, it deliberately focuses on students who do not excel in science and math courses and students who are unsure about a college career. Second, it targets typically underrepresented minorities in the technology fields, namely blacks, Hispanics, and women. Third, it introduces these students to high-tech career options which do not require 4 years of college. The goal of the program is to make the students aware of technician-level careers and to give them a chance to learn the skills needed for such careers in order to help them make an informed decision about their future. 相似文献

The Undergraduate Research Student Self-Assessment (URSSA): Validation for Use in Program Evaluation
This article examines the validity of the Undergraduate Research Student Self-Assessment (URSSA), a survey used to evaluate undergraduate research (UR) programs. The underlying structure of the survey was assessed with confirmatory factor analysis; also examined were correlations between different average scores, score reliability, and matches between numerical and textual item responses. The study found that four components of the survey represent separate but related constructs for cognitive skills and affective learning gains derived from the UR experience. Average scores from item blocks formed reliable but moderate to highly correlated composite measures. Additionally, some questions about student learning gains (meant to assess individual learning) correlated to ratings of satisfaction with external aspects of the research experience. The pattern of correlation among individual items suggests that items asking students to rate external aspects of their environment were more like satisfaction ratings than items that directly ask about student skills attainment. Finally, survey items asking about student aspirations to attend graduate school in science reflected inflated estimates of the proportions of students who had actually decided on graduate education after their UR experiences. Recommendations for revisions to the survey include clarified item wording and increasing discrimination between item blocks through reorganization.Undergraduate research (UR) experiences have long been an important component of science education at universities and colleges but have received greater attention in recent years, as they have been identified as important ways to strengthen preparation for advanced study and work in the science fields, especially among students from underrepresented minority groups (Tsui, 2007 ; Kuh, 2008 ). UR internships provide students with the opportunity to conduct authentic research in laboratories with scientist mentors, as students help design projects, gather and analyze data, and write up and present findings (Laursen et al., 2010 ). The promised benefits of UR experiences include both increased skills and greater familiarity with how science is practiced (Russell et al., 2007 ). While students learn the basics of scientific methods and laboratory skills, they are also exposed to the culture and norms of science (Carlone and Johnson, 2007 ; Hunter et al., 2007 ; Lopatto, 2010 ). Students learn about the day-to-day world of practicing science and are introduced to how scientists design studies, collect and analyze data, and communicate their research. After participating in UR, students may make more informed decisions about their future, and some may be more likely to decide to pursue graduate education in science, technology, engineering, and mathematics (STEM) disciplines (Bauer and Bennett, 2003 ; Russell et al., 2007 ; Eagan et al. 2013 ).While UR experiences potentially have many benefits for undergraduate students, assessing these benefits is challenging (Laursen, 2015 ). Large-scale research-based evaluation of the effects of UR is limited by a range of methodological problems (Eagan et al., 2013 ). True experimental studies are almost impossible to implement, since random assignment of students into UR programs is both logistically and ethically impractical, while many simple comparisons between UR and non-UR groups of students suffer from noncomparable groups and limited generalizability (Maton and Hrabowski, 2004 ). Survey studies often rely on poorly developed measures and use nonrepresentative samples, and large-scale survey research usually requires complex statistical models to control for student self-selection into UR programs (Eagan et al., 2013 ). For smaller-scale program evaluation, evaluators also encounter a number of measurement problems. Because of the wide range of disciplines, research topics, and methods, common standardized tests assessing laboratory skills and understandings across these disciplines are difficult to find. While faculty at individual sites may directly assess products, presentations, and behavior using authentic assessments such as portfolios, rubrics, and performance assessments, these assessments can be time-consuming and not easily comparable with similar efforts at other laboratories (Stokking et al., 2004 ; Kuh et al., 2014 ). Additionally, the affective outcomes of UR are not readily tapped by direct academic assessment, as many of the benefits found for students in UR, such as motivation, enculturation, and self-efficacy, are not measured by tests or other assessments (Carlone and Johnson, 2007 ). Other instruments for assessing UR outcomes, such as Lopatto’s SURE (Lopatto, 2010 ), focus on these affective outcomes rather than direct assessments of skills and cognitive gains.The size of most UR programs also makes assessment difficult. Research Experiences for Undergraduates (REUs), one mechanism by which UR programs may be organized within an institution, are funded by the National Science Foundation (NSF), but unlike many other educational programs at NSF (e.g., TUES) that require fully funded evaluations with multiple sources of evidence (Frechtling, 2010 ), REUs are generally so small that they cannot typically support this type of evaluation unless multiple programs pool their resources to provide adequate assessment. Informal UR experiences, offered to students by individual faculty within their own laboratories, are often more common but are typically not coordinated across departments or institutions or accountable to a central office or agency for assessment. Partly toward this end, the Undergraduate Research Student Self-Assessment (URSSA) was developed as a common assessment instrument that can be compared across multiple UR sites within or across institutions. It is meant to be used as one source of assessment information about UR sites and their students.The current research examines the validity of the URSSA in the context of its use as a self-report survey for UR programs and laboratories. Because the survey has been taken by more than 3400 students, we can test some aspects of how the survey is structured and how it functions. Assessing the validity of the URSSA for its intended use is a process of testing hypotheses about how well the survey represents its intended content. This ongoing process (Messick, 1993 ; Kane, 2001 ) involves gathering evidence from a range of sources to learn whether validity claims are supported by evidence and whether the survey results can be used confidently in specific contexts. For the URSSA, our method of inquiry focuses on how the survey is used to assess consortia of REU sites. In this context, survey results are used for quality assurance and comparisons of average ratings over years and as general indicators of program success in encouraging students to pursue graduate science education and scientific careers. Our research questions focus on the meaning and reliability of “core indicators” used to track self-reported learning gains in four areas and the ability of numerical items to capture student aspirations for future plans to attend graduate school in the sciences. 相似文献

This paper considers some of the reasons why motivated students in suitable learning environments may fail to learn from competent teachers. It draws upon work in the psychology of learning, and the considerable body of research that has been undertaken to explore the nature and origin of learners' alternative conceptions in science. A synthesis of ideas from this previous work suggests a simple typology of 'learning impediments' in terms of the mismatch between the learner's cognitive structure and the teacher's expectations. It is suggested that this classification system may be a useful tool that, alongside techniques to probe prior knowledge, can help teachers diagnose and overcome such impediments to intended learning, and thus make teaching more effective. Although deriving from research into the learning of science, it is suggested that the typology can be applied to conceptual learning across the curriculum. 相似文献

This study explores middle school students’ aspirations in science, technology, engineering, and medical (STE-M) careers by analyzing survey data during their eighth and ninth grade years from an ethnically and economically diverse sample of Southern California urban and suburban public school students (n = 493). Students were classified based on their responses to questions about their science ability beliefs and subjective task values using latent class analysis (LCA). Four distinct groups of students were identified: Science is Me; I Value Science But Don’t Do It Well; I Can Do Science but I Don’t Value It Highly; and Science is Not Me. Few students (22 %) were classified as having strong science ability beliefs, and only a third as strongly valuing learning/doing science; a majority (57 %) were in the Science is Not Me category, underscoring the scope of the challenge to invite more young people to want to learn science. As predicted, students who believed they could do science and valued science were more likely than others to indicate interest in STE-M careers. This relationship between perceptions and aspirations was true regardless of gender, ethnicity, and type of STE-M field, but varied depending on socioeconomic status. Using LCA to organize information about students’ science self-perceptions may help target specific interventions to student interests and aspirations and better support and encourage their persistence in STE-M careers. 相似文献

Information and choice of A‐level subjects: A cluster randomised controlled trial with linked administrative data 
下载免费PDF全文
下载免费PDF全文 We estimated the effects of an intervention which provided information about graduate wages to 5593 students in England, using a blinded cluster randomised controlled trial in 50 schools (registration: AEARCTR‐0000468). Our primary outcome was students’ choice of A‐level subjects at age 16. We also recorded the students’ expectations of future wages and the A‐level subjects they intended to take before and after the intervention, and linked their data into national administrative school examination records. We found that an hour‐long lesson on information about graduate wages affected students’ beliefs about and choice of subject. They were more likely to take mathematics and less likely to take biology and computing. We found strong evidence that mediating factors such as their beliefs about average graduate salaries and their own likely salary in each subject were affected by the intervention. This suggests that providing accessible and credible information on labour market consequences of school choices may influence students’ decisions. In the light of concerns about the quality of careers guidance for school students and expectations that educational choices should be well‐informed, the study has clear implications for policy and practice. 相似文献

Among science educators, current interest in undergraduate research (UR) is influenced both by the traditional role of the
research apprenticeship in scientists’ preparation and by concerns about replacing the current scientific workforce. Recent
research has begun to demonstrate the range of personal, professional, and intellectual benefits for STEM students from participating
in UR, yet the processes by which student-advisor interactions contribute to these benefits are little understood. We employ
situated learning theory (Lave and Wenger, Situated learning: legitimate peripheral participation, Cambridge University Press,
Cambridge in 1991) to examine the role of student-advisor interactions in apprenticing undergraduate researchers, particularly in terms of
acculturating students to the norms, values, and professional practice of science. This qualitative study examines interviews
with a diverse sample of 73 undergraduate research students from two research-extensive institutions. From these interviews,
we articulate a continuum of practices that research mentors employed in three domains to support undergraduate scientists-in-training:
professional socialization, intellectual support, and personal/emotional support. The needs of novice students differed from
those of experienced students in each of these areas. Novice students needed clear expectations, guidelines, and orientation
to their specific research project, while experienced students needed broader socialization in adopting the traits, habits,
and temperament of scientific researchers. Underrepresented minority students, and to a lesser extent, women, gained confidence
from their interactions with their research mentors and broadened their future career and educational possibilities. Undergraduate
research at research-extensive universities exemplifies a cycle of scientific learning and practice where undergraduate researchers
are mentored by graduate students and postdoctoral researchers, who are themselves apprentices to faculty members. As such,
research mentors of undergraduate students should be aware of the dual scientific and educational aspects of their advising
role and its significance in shaping students’ identities and career trajectories. 相似文献

This paper shows that LGBT students in the U.S. are less likely to graduate from high school and attend college. These differences persist after controlling for demographic characteristics, family background, state and school fixed effects. Relatedly, LGBT students have lower educational expectations, a lower sense of school belonging, and are more likely to have been affected by discrimination. 相似文献

BACKGROUND CHARACTERISTICS AS PREDICTORS OF ACADEMIC SELF-CONFIDENCE AND ACADEMIC SELF-EFFICACY AMONG GRADUATE SCIENCE AND ENGINEERING STUDENTS 总被引：1，自引：0，他引：1
This study uses data from the 1995-96 Graduate Experience Project to explore differences among, and possible predictors of, academic self-confidence, academic self-efficacy, and outcome expectations of entering graduate students in science and engineering. The results suggest that at time of entry, women and U.S. minority graduate students entered with similar academic credentials and academic expectations as their Anglo male peers. Further, gender was not found to be a significant factor in predicting academic self-confidence, academic self-efficacy, or careerrelated outcome expectations. Rather, student perceptions of academic preparedness, status-related disadvantages, and expectations about faculty/student interactions emerged as significant predictors of academic self-efficacy and career-related outcome expectations. 相似文献

This paper examines the experiences reported by scientists and graduate students regarding the experiences that first engaged them in science. The interviews analysed for this paper come from Project Crossover, a mixed‐methods study of the transition from graduate student to PhD scientist in the fields of chemistry and physics. This analysis involved review of 116 interviews collected from graduate students and scientists and focused on the timing, source, and nature of their earliest interest in science. The majority (65%) of participants reported that their interest in science began before middle school. Females were more likely to report that their interest was sparked by school‐related activities, while most males recounted self‐initiated activities. Our findings indicate that current policy efforts (which focus on high school science reform) to increase the numbers of students studying in the science fields, may be misguided. 相似文献

While the achievement gap in science exists in the US, research associated with our investigation reveals some high school science programs serving diverse student bodies are successfully closing the gap. Using a mixed methods approach, we identified and investigated ten high schools in a large Southwestern state that fit the definition of “highly successful, highly diverse”. By conducting interviews with science liaisons associated with each school and reviewing the literature, we developed a rubric identifying specific characteristics associated with successful science programs. These characteristics and practices included setting high expectations for students, providing extensive teacher support for student learning, and utilizing student-centered pedagogy. We used the rubric to assess the successful high school science programs and compare them to other high school science programs in the state (i.e., less successful and less diverse high school science programs). Highly successful, highly diverse schools were very different in their approach to science education when compared to the other programs. The findings from this study will help schools with diverse students to strengthen hiring practices, enhance teacher support mechanisms, and develop student-focused strategies in the classroom that increase science achievement. 相似文献

Resistance to more humanistic forms of science education is an endemic and persistent feature of university scientists as
well as school science teachers. This article argues that science education researchers should pay more attention to its origins
and to the subtleties of its stubborn influence. The paper explores some of the imperatives which dominate the continuing
practices of teachers; the linkages between school and university science; and re-considers the relationships between learning
science, learning to do science and learning about science. It draws on recent, prominent publications, as well as neglected and rather more contentious material, to underline the unhelpfully
narrow view of science held by those who defend the traditional disciplinary influences of biology, chemistry and physics.
Suggestions are made as to where those of a more radical and determined disposition should direct their attention in the interests
of improved education, vital scientific progress as well as human survival. It is argued that university science must change
in order to ensure that teachers better help their students to learn, do and appreciate science. 相似文献

The present research was designed to investigate the reaction of secondary school students to the communication code that the press uses in science articles: it attempts to trace which communication techniques can be of potential use in science education. The sample of the research consists of 351 secondary school students. The research instrument is a questionnaire, which attempts to trace students’ preferences regarding newspaper science articles, to explore students’ attitudes towards the science articles published in the press and to investigate students’ reactions towards four newspaper science articles. These articles deal with different aspects of science and reflect different communication strategies. The results of the research reveal that secondary school students view the communication codes used in press science articles as being more interesting and comprehensible than those of their science textbooks. Predominantly, they do not select science articles that present their data in a scientific way (diagrams and abstract graphs). On the contrary, they do select science articles and passages in them, which use an emotional/‘poetic’ language with a lot of metaphors and analogies to introduce complex science concepts. It also seems that the narrative elements found in popularized science articles attract students’ interest and motivate them towards further reading. 相似文献

How do university students perceive the key relationship between their university education and the labour market? This article describes the perceptions that 827 Egyptian and Omani seniors—both males and females, studying commerce, education, and engineering—hold about that relationship. For these students, a major motivation for attending university is their perception that it will help them get better and more secure employment. They are also confident it will help them enter appropriate careers. However, they are less satisfied with the way in which university curricula prepare them effectively for appropriate careers. In addition, an analysis by nationality, gender, and field of study revealed statistically significant differences among the participants. The Omani students are more confident about their education than the Egyptians—who call for more reform of their curricula to fit labour market requirements. Women are more motivated than men to enter a career after university. The field of study had only a small impact on students’ perceptions of this key relationship. 相似文献

This study investigated the relation between multidimensional aspects of high school students' perceptions of their parental involvement and their achievement. It explored differences in socio-economic backgrounds, ethnicity, gender, and higher and lower achieving students, and a structural model was developed to further investigate these relations. A parental involvement questionnaire and measures of efficacy, liking and achievement in mathematics and reading were administered to a sample of 1,554 New Zealand high school students from 59 schools. In the view of students, there is support for parents to be talking to their children about learning and schooling and having high expectations of them and their future in learning, especially for lower achieving students. Students who claim that their parents are talking with their teachers or attending school meetings are more likely to have lower achievement. The implications from this study relate to developing student self-regulation for learning in home, providing more surface than deeper learning as homework, and assisting parents to learn the language of learning and schooling. 相似文献

The Importance of Teaching and Learning Nature of Science in the Early Childhood Years 总被引：1，自引：0，他引：1

Though research has shown that students do not have adequate understandings of nature of science (NOS) by the time they exit
high school, there is also evidence that they have not received NOS instruction that would enable them to develop such understandings.
How early is “too early” to teach and learn NOS? Are students, particularly young students, not capable of learning NOS due
to developmental unreadiness? Or would young children be capable of learning about NOS through appropriate instruction? Young
children (Kindergarten through third grade) were interviewed and taught about NOS in a variety of contexts (informal, suburban,
and urban) using similar teaching strategies that have been found effective at teaching about NOS with older students. These
teaching strategies included explicit decontextualized and contextualized NOS instruction, through the use of children’s literature,
debriefings of science lessons, embedded written NOS assessments, and guided inquiries. In each context the researchers interviewed
students prior to and after instruction, videotaped science instruction and maintained researcher logs and field notes, collected
lesson plans, and copies of student work. The researchers found that in each setting young children did improve their understandings
of NOS. Across contexts there were similar understandings of NOS aspects prior to instruction, as well as after instruction.
There were also several differences evident across contexts, and across grade levels. However, it is clear that students as
young as kindergarten are developmentally capable of conceptualizing NOS when it is taught to them. The authors make recommendations
for teaching NOS to young children, and for future studies that explore learning progressions of NOS aspects as students proceed
through school. 相似文献

Graphs are commonly used in textbooks and educational software, and can help students understand science and social science data. However, students sometimes have difficulty comprehending information depicted in graphs. What makes a graph better or worse at communicating relevant quantitative information? How can students learn to interpret graphs more effectively? This article reviews the cognitive literature on how viewers comprehend graphs and the factors that influence viewers' interpretations. Three major factors are considered: the visual characteristics of a graph (e.g., format, animation, color, use of legend, size, etc.), a viewer's knowledge about graphs, and a viewer's knowledge and expectations about the content of the data in a graph. This article provides a set of guidelines for the presentation of graphs to students and considers the implications of graph comprehension research for the teaching of graphical literacy skills. Finally, this article discusses unresolved questions and directions for future research relevant to data presentation and the teaching of graphical literacy skills. 相似文献
