The Depiction of Native Americans in Recent (1991–2004) Secondary American History Textbooks: How Far Have We Come?     

Tony R. Sanchez 《Equity & Excellence in Education》2013,46(4):311-320

This study examined 15 secondary American history textbooks to evaluate their accuracy in depicting Native Americans as a follow-up to studies by Costo and Henry (1970) Costo, R. and Henry, J., eds. 1970. Textbooks and the American Indian, The Indian Historian Press.  [Google Scholar] and Loewen (1995) Loewen, J. 1995. Lies my teacher told me: Everything your American history textbook got wrong, New York: The New York Press.  [Google Scholar]. The criteria embodied an authenticity guideline based upon the Five Great Values with a rating scale between 1 (lowest) and 5 (highest). The results indicate that only three of the textbooks rated above average. Though generally the textbooks have improved in quantity of cultural information, better treatments must be pursued that reflect more accurate and comprehensive accounts. The challenge lies in assisting educators' acquisition of knowledge and familiarity with Native cultures as they are depicted in textbooks, an endeavor that will further assist these teachers in adopting and utilizing proper textbooks.  相似文献

Abstract

The aim of the study is the modelling of training responses with a variable dose-response model in a sport discipline that requires highly complex coordination. We propose a method to optimise the training programme plan using the potential maximal performance gain associated with overload and tapering periods. Data from five female elite gymnasts were collected over a 3-month training period. The relationship between training amounts and performance was then assessed with a non-linear model. The optimal magnitude of training load reduction and its duration were investigated with and without an overload period using simulation procedures based on individual responses to training. The correlation between actual and modelled performances was significant (R ² = 0.81 ± 0.02, P < 0.01). The standard error was 2.7%. Simulations revealed that taper preceded by an overload period allows a higher performance to be achieved compared to an absence of overload period (106.3 ± 0.3% vs. 105.1 ± 0.3%). With respect to the pre-taper load, the model predicts that optimal load reductions during taper were 48.4 ± 0.7% and 42.5 ± 1.0% for overloading and non-overloading strategies, respectively. Moreover, optimal durations of the taper period were 34 ± 0.5 days and 22 ± 0.5 days for overloading and non-overloading strategies, respectively. In conclusion, the study showed that the variable dose-response model describes precisely the training response in gymnasts.  相似文献   

Fixing the Cracks in Education So No One Slips Through   总被引：1，自引：1，他引：0  

Heliodoro T. Sanchez Jr. 《The Educational forum》2013,77(4):348-356

Education acts in this country have been created with the express purpose of preventing students from slipping through the cracks. Unfortunately, legislation has not been successful. By disaggregating the student dropout rate in Texas and juxtaposing this information to the prison influx rate in 2001, a profile of the population entering Texas prisons emerges. Both data and various schools of thought are examined in search of the underlying factors inherent in juvenile delinquency, as well as feasible, practical solutions to such a complex conundrum.  相似文献   

POSTCOLLEGE EARNINGS OF FORMER STUDENTS OF CALIFORNIA COMMUNITY COLLEGES: Methods, Analysis, and Implications     

Jorge R. Sanchez  Frankie Santos Laanan  W. Charles Wiseley 《Research in higher education》1999,40(1):87-113

In the wake of new federal and state mandates,community colleges are faced with demands to provideaccountability reports on student outcomes. With the useof the Employment Development Department Unemployment Insurance (EDD-UI) wage record data, along withthe California Community Colleges Chancellor's OfficeManagement Information System administrative database,this study sought to investigate the extent to which completing an associate degree andvocational certificate impacts the postcollege earningsof students. Based on information from 700,564 studentsfrom California community colleges during the 1992-93 academic year, the findings suggest thatstudents' gains from first year out of college to thirdyear out will differ by age group. Among economicallydisadvantaged students, a strong positive relationship exists between educational attainment andpostcollege gains. An important finding among vocationalstudents is that as women complete more education, theearnings gap closes between men and women. Finally, this study raises several policy implicationsand presents suggestions for future research.  相似文献   

Learning from human cadaveric prosections: Examining anxiety in speech therapy students          下载免费PDF全文

Juan Jose Criado‐Álvarez  Jaime González González  Carmen Romo Barrientos  Isabel Ubeda‐Bañon  Daniel Saiz‐Sanchez  Alicia Flores‐Cuadrado  Juan Carlos Albertos‐Marco  Alino Martinez‐Marcos  Alicia Mohedano‐Moriano 《Anatomical sciences education》2017,10(5):487-494

Human anatomy education often utilizes the essential practices of cadaver dissection and examination of prosected specimens. However, these exposures to human cadavers and confronting death can be stressful and anxiety‐inducing for students. This study aims to understand the attitudes, reactions, fears, and states of anxiety that speech therapy students experience in the dissection room. To that end, a before‐and‐after cross‐sectional analysis was conducted with speech therapy students undertaking a dissection course for the first time. An anonymous questionnaire was administered before and after the exercise to understand students' feelings and emotions. State‐Trait Anxiety Inventory questionnaires (STAI‐S and STAI‐T) were used to evaluate anxiety levels. The results of the study revealed that baseline anxiety levels measured using the STAI‐T remained stable and unchanged during the dissection room experience (P > 0.05). Levels of emotional anxiety measured using the STAI‐S decreased, from 15.3 to 11.1 points (P < 0.05). In the initial phase of the study, before any contact with the dissection room environment, 17% of students experienced anxiety, and this rate remained unchanged by end of the session (P > 0.05). A total of 63.4% of students described having thoughts about life and death. After the session, 100% of students recommended the dissection exercise, giving it a mean score of 9.1/10 points. Anatomy is an important subject for students in the health sciences, and dissection and prosection exercises frequently involve a series of uncomfortable and stressful experiences. Experiences in the dissection room may challenge some students' emotional equilibria. However, students consider the exercise to be very useful in their education and recommend it.

Developing Coherent Conceptual Storylines: Two Elementary Challenges     

Deborah Hanuscin  Kelsey Lipsitz  Dante Cisterna-Alburquerque  Kathryn A. Arnone  Delinda van Garderen  Zandra de Araujo  Eun Ju Lee 《Journal of Science Teacher Education》2016,27(4):393-414

The ‘conceptual storyline’ of a lesson refers to the flow and sequencing of learning activities such that science concepts align and progress in ways that are instructionally meaningful to student learning of the concepts. Research demonstrates that when teachers apply lesson design strategies to create a coherent science content storyline, student learning is positively impacted (Roth et al., 2011). Because the conceptual storyline is often implicit within a lesson, and teachers often have difficulty articulating this aspect of lesson design (Lo et al., 2014), our professional development program engages elementary teachers in analyzing and developing graphic representations of a lesson’s conceptual storyline to make that element explicit. In this exploratory study, we present typologies that represent two primary challenges teachers faced in developing coherent conceptual storylines in their lesson design, and examine the extent to which professional development enhanced their capacity to develop a coherent conceptual storyline.  相似文献   

The Methodological Challenges of Measuring Student Learning,Degree Attainment,and Early Labor Market Outcomes in Higher Education     

Tatiana Melguizo  Gema Zamarro  Tatiana Velasco  Fabio J. Sanchez 《Journal of research on educational effectiveness》2017,10(2):424-448

The main objective of this study is to empirically test a number of theory-based models (i.e., fixed effects [FE], random effects [RE], and aggregated residuals [AR]) to measure the generic knowledge as well as the degree attainment rates and early labor outcomes gained by students in different programs and institutions in higher education. Our results show the importance of addressing the issue of student selection into programs and institutions in order to reduce selection bias, and they provide suggestive evidence in favor of using FE models. Our findings also confirm our hypotheses that rankings of specific college-program combinations change depending on the different educational and labor outcome measures considered. This finding emphasizes the need to use complementary indicators related to the mission of the specific postsecondary institutions that are being ranked. Given the sensitivity of the models to different model specifications, it is not clear whether they should be used to make any high-stakes decisions in higher education. They could, however, serve as part of a broader set of indicators to support programs and colleges as part of a formative evaluation.  相似文献   

Design and application of learning environments based on integrative problems     

Iván Sanchez  Liliana Neriz 《European Journal of Engineering Education》2008,33(4):445-452

This work reports on the results obtained from the application of learning environments on the basis of one integrative problem and a series of other smaller problems that limit the contents to be investigated and learned by the students. This methodology, which is a variation to traditional problem-based learning approaches, is here illustrated in terms of its application in an engineering economics course, a subject that is taught in most engineering programs. The purpose of this methodology is to improve students’ learning, which is measured through the students’ academic performance and their learning strategies, and to characterise them as a function of these variables. The results obtained after the systematic application of this methodology are positive. The surveyed students showed significant changes in the examined variables as well as in their satisfaction and motivation level, and in their commitment to learning.  相似文献   

Threats of violence in schools: The Dallas independent school district's response

School violence has become a primary concern for parents, students, school personnel, and the public. As a result, educators are searching for methods to prevent violent acts perpetrated by youth. Dallas Public Schools developed procedures for assessing the potential for violence among children who express intent to harm others. The Dallas Violence Risk Assessment (DVRA) was developed to evaluate students who have made verbal or written threats of violence and to assist school staff in determining appropriate intervention strategies. This article describes the development of the DVRA, and presents case studies utilizing the DVRA procedures. Challenges and implications of the use of the DVRA are also discussed. © 2001 John Wiley & Sons, Inc.  相似文献
