The enrollment and transfer behaviors of college students are diverse. As a result, college students travel various pathways to the baccalaureate degree. The purpose of this qualitative study was to better understand the lived experience of students who entered higher education through an associate of applied science (AAS) program and then continued in higher education to earn a bachelor of applied science (BAS) degree. To explore this phenomenon, eight participants completed two in-depth interviews regarding their lived experience as students on this educational pathway. Five structures emerged from the data to frame the participants' experiences on the AAS to BAS pathway: disengagement, doubt, knowledge of something different, significant relationships, and transformation. These five structures interacted in discrete ways to characterize the participants' experiences as pushing through disillusionment related to education, the profession, and self. The participants' moving through three dimensions of disillusionment along the pathway formed the meaning and the essence of the phenomenon, dogged determinism. The findings elaborate on the themes that contributed to heating up, or raising the educational aspirations of these career-technical students.  相似文献

Assessment data must be valid for the purpose for which educators use them. Establishing evidence of validity is an ongoing process that must be shared by test developers and test users. This study examined the predictive validity and the diagnostic accuracy of universal screening measures in reading. Scores on three different universal screening tools were compared for nearly 500 second‐ and third‐grade students attending four public schools in a large urban district. Hierarchical regression and receiver operating characteristic curves were used to examine the criterion‐related validity and diagnostic accuracy of students’ oral reading fluency (ORF), Fountas and Pinnell Benchmark Assessment System (BAS) scores, and fall scores from the Measures of Academic Progress for reading (MAP). Results indicated that a combination of all three measures accounted for 65% of the variance in spring MAP scores, whereas a reduced model of ORF and MAP scores predicted 60%. ORF and BAS scores did not meet standards for diagnostic accuracy. Combining the measures improved diagnostic accuracy, depending on how criterion scores were calculated. Implications for practice and future research are discussed.  相似文献

ABSTRACT

This paper focuses on a recently conceptualized construct—sense of authentic inner-compass (AIC)—and two parenting practices promoting it: basic autonomy-support (BAS) and inherent value-demonstration (IVD). Rooted in self-determination theory, sense of AIC refers to the perception that we have self-guiding values, aspirations, and goals, which function like an ‘authentic inner-compass’ that informs us on what we truly value and need. The utility of this construct for understanding morality-related phenomena also in cultures not emphasizing autonomy and authenticity, is demonstrated by a study conducted in two widely different cultures: Bedouin and Jews in Israel. As expected, across cultures, the practices of BAS and IVD were associated with sense of AIC, which then predicted adolescents’ resistance to peer-pressure to engage in antisocial behaviors. Invariance analysis showed a similar pattern across cultures. Discussion focuses on implications of the AIC concept for various moral behaviors, and for value-oriented parenting and moral education.  相似文献

The purpose of this study was to test Beatty and McCroskey's communibiological model of trait verbal aggressiveness. In general, this model views trait verbal aggressiveness as an expression of temperament; specifically, that trait verbal aggressiveness represents low thresholds for the fight or flight (FFS) neurobiological system. This model further contends that behavioral inhibition circuitry (BIS) moderates FFS activation by tempering aggressive impulses, otherwise FFS activation would manifest itself in the form of physical rather than verbal attacks. Beatty and McCroskey (1997) propose that low thresholds for stimulating the behavioral activation system (BAS) should be related to trait verbal aggressiveness to the extent that the construct involves a proactive rather than a purely reactive interpersonal function. Because previous research indicated that psychoticism (P), neuroticism (N) and extroversion (E) represent psychological manifestations of the FFS, BIS, and BAS systems, respectively, hypotheses linking P, N, and E to trait verbal aggressiveness (VAS) were tested. A multiple regression equation based on disattenuated correlations explained approximately 46% of the variance in VAS scores. Specifically, (1) the results for P and N were consistent with predictions derived from Beatty and McCroskey's model, and (2) the results for E were indicative of a purely reactive function of trait verbal aggressiveness. Implications for theory and research are discussed.  相似文献

Silicon carbide (SiC) composites were prepared by hot-press sintering from α-SiC starting powders with BaAl2Si2O8 (BAS). The effects of additives on densification, microstructure, flexural strength, and fracture behavior of the liquid phase sintered (LPS) SiC composites were investigated. The results show that the served BAS effectively promotes the densification of SiC composites. The flexural strength and fracture toughness of the SiC composites can reach a maximum value of 454 MPa and 5.1 MPa·m1/2, respectively, for 40% (w/w) BAS/SiC composites. SiC grain pullout, crack deflection, and crack bridging were main toughening mechanisms for the sintered composites.  相似文献

This study explored the problem-solving schemas developed by 7th-grade pre-algebra students as they participated in a teaching experiment that was designed to help students develop effective schemas for solving algebraic problem situations involving contexts of (1) growth and change and (2) size and shape. This article describes the qualities and types of schemas that students developed through examples of problems used to develop schemas, examples of students' reasoning and writing, and excerpts from student interviews. Findings from the study indicated that there is a link between the type of generalizations students construct and the schemas they are forming. By using these schemas students recognize, extend, and generalize patterns and quantitative relationships both verbally and symbolically. This revised version was published online in July 2006 with corrections to the Cover Date.  相似文献

This study investigated the kinds of dialogues utilized by Open University students while studying an intermediate level physics course. Research objectives were twofold: to document what dialogue types, mediated through which resources, were (1) generally utilized by students as they learned; and (2) were specifically utilized by students to overcome conceptual difficulties. It was found that all students initially chose individual study characterized by intrapersonal dialogue. Only when individual study failed did students opt for interpersonal dialogue. This finding conflicts with the assumed importance often ascribed to interpersonal dialogue by some distance education theorists.  相似文献

More emphasis is now being placed on active learning in medical education. Ultrasound is an active learning tool that can be used to supplement didactic instruction. This study describes a self-guided activity for learning floor of mouth ultrasound. Thirty-three first year medical students learned floor of mouth scan technique and ultrasound anatomy through a brief PowerPoint module. They subsequently performed the scan on a standardized patient. Each student was asked to label the floor of mouth muscles on the image he or she acquired. After the activity, the students were given a quiz on anatomic relationships of the floor of mouth. Perceptions about the activity were collected through a survey. All 33 students obtained a floor of mouth image within a three minute time limit. Twenty-four (73%) students were able to completely and accurately label the image in time. The mean score on the muscle relationships quiz was 93%. Overall perceptions were very positive with most students expressing a “high” or “very high” level of interest in incorporating similar self-guided activities within the curriculum. This study showed that it is feasible for students to learn scan technique and recognize relevant ultrasound anatomy in an independent fashion through a brief active learning module. Furthermore, the students found the activity enjoyable. The implication is that similar activities could be developed which would provide additional ways to incorporate active learning strategies.  相似文献

This study documents our efforts to implement an ‘ethic of discomfort’ and a ‘pedagogy of discomfort’ in our undergraduate multicultural teacher education courses. Commitments to these moral imperatives inherently involve emotional work for teacher candidates and teacher educators. Such emotional work, particularly in academia, is often invisible and disincentivized. This study examines the following: (1) grappling with students’ emotional reactions that stem from discomfort, (2) engaging in public emotional discourses, (3) negotiating the political dimensions of teaching diverse students, and (4) remaining emotionally available to students as they work through these ideas in their own lives. The implications of this study address the types of preparation and support teacher educators need to facilitate the transformative potential of a pedagogy and an ethic of discomfort. While pre-service teacher education is considered a safe and productive learning space for students to be discomforted, questions are posed regarding the safety for pre-tenured teacher educators involved in this process. We offer a typology of emotional work from a teacher educator perspective in teaching multicultural education.  相似文献

The transition through the first year of university study is challenging for the majority of students. For students from Culturally and Linguistically Diverse (CALD) backgrounds, commencing studies in an English-Medium Instruction (EMI) university program presents a number of specific challenges. These students are faced with meeting both language demands as well as learning expectations of the institution, which often differ markedly from their previous formal learning experiences. Developing CALD students’ digital literacy practices has been shown to lead to improved academic performance, success and retention in some higher education settings. This paper focuses on the digital literacy practices of undergraduates at a national public university in a Gulf State. Results from a survey and focus groups are analysed to identify the students’ access to and use of digital technologies, in order to better understand how their academic success can be enhanced through digital literacy development. The study identifies a disconnect between students’ perceptions of their digital capabilities and the institutional requirements for study. The research recommends that providing integrated, institution-wide digital literacy development focused on accessing, assessing and incorporating online resources in their work, will help improve transitioning CALD students’ preparedness for undergraduate study in this and other EMI universities.

There has been extensive research on children’s understanding of evaporation, but representational issues entailed in this understanding have not been investigated in depth. This study explored three students’ engagement with science concepts relating to evaporation through various representational modes, such as diagrams, verbal accounts, gestures, and captioned drawings. This engagement entailed students (a) clarifying their thinking through exploring representational resources; (b) developing understanding of what these representations signify; and (c) learning how to construct representational aspects of scientific explanation. The study involved a sequence of classroom lessons on evaporation and structured interviews with nine children, and found that a focus on representational challenges provided fresh insights into the conceptual task involved in learning science. The findings suggest that teacher‐mediated negotiation of representational issues as students construct different modal accounts can support enriched learning by enabling both (a) richer conceptual understanding by students; and (b) enhanced teacher insights into students’ thinking.  相似文献

This study investigates how student dissent behaviors are affected by student predispositions (i.e., math anxiety and self‐efficacy) in supply chain related courses. The data support a model in which students’ vengeful dissent behaviors are indirectly induced by these predispositions through the mediation of perceived immediacy. It is critical for instructors to understand the relationship between these variables to help improve the classroom environment for students, which this study helps to accomplish. Instructors of quantitative courses may need to engage students with predispositions in communication outside of the classroom to foster effective relationship building away from an environment that triggers students’ anxiety.  相似文献

Fourth-grade follow-up achievement outcome data of placed and nonplaced transition extra-year school readiness samples indicate a nonsignificant standardized score difference, as noted in the second-grade findings. New analysis of correlation data indicates that within-sample age distribution shows a positive correlation with standardized achievement test scores in a study sample of non-at-risk students nonretained or recommended for retention. This age-achievement correlation is strong in kindergarten, with decreased effects by second and fourth grade. Four study samples of at-risk students (students retained in a transition extra-year school readiness program, students recommended and eligible for such placement but not placed, students retained in kindergarten through second grade, and students held out of school prior to kindergarten) reflect moderate inverse (negative) correlations between age and achievement test scores, with increasing inverse effects in fourth grade. Effect analysis and implications are discussed. © 1996 John Wiley & Sons, Inc.  相似文献

In the 21st century, the use of information technology in the classroom is advancing rapidly, especially in higher education. The Internet, through social networking, has made it possible for students to learn and teachers to teach outside the classroom walls. Facebook in particular has made it possible for students to interact and communicate with their teachers and among themselves about their progress and about the problems they encounter in learning. Yet, limited research exists on the use of Facebook in education in Sub‐Saharan Africa more especially in Botswana. This is in spite of the observation that Sub‐Saharan Africa is the fastest growing Internet population with a growth of more than 2500% between 2000 and 2011. This study therefore set out to examine (1) the students' interest in using Facebook to facilitate group work activities in the Advanced Oral Presentation Skills course; (2) whether the students interact and communicate using Facebook on matters relating to the Advanced Oral Presentations course; (3) whether the students benefitted from using Facebook for learning advanced oral presentation skills; and (4) what challenges the students encountered when using Facebook in the Advanced Oral Presentations course. In this trial study, students were allocated groups and assigned to conduct their group activities via Facebook. Although this was optional, more than 80% of the groups opted for Facebook and less than 20% chose to do their group work traditionally. A follow‐up evaluation of the experiment was done through a questionnaire and interviews. The findings suggest that Facebook could facilitate student communication and interaction about group assignments.  相似文献

Currently, 18–21-year-olds account for 60% of university students; mature students represent 40%. Attrition (dropping out) can be related to discordance between a student's perception of the university created through branding and marketing of the institution and the university's actual environment and offerings delivery. This study adds to this research by indicating: (1) retention factors do vary for first-year students, depending on age and (2) academic environment is key to institutional commitment among non-traditional (22–55+ years of age) students whereas university and organizational support features contribute more to traditional (17–21 years of age) students' campus integration.  相似文献
