This is the final paper in a five-paper series describing our national study of the teaching and learning of cosmology in general education astronomy college-level courses. A significant portion of this work was dedicated to the development of five new Lecture-Tutorials that focus on addressing the conceptual and reasoning difficulties that our research shows students have with frequently taught cosmology topics, such as the expansion of the universe, the Big Bang, and dark matter. We conducted a systematic investigation of the implementation of these new Lecture-Tutorials and resulting learning gains in order to test the efficacy of these new Lecture-Tutorials. Our investigation included classroom observations, results from pre–post testing using four conceptual cosmology surveys, and comparisons between classes in terms of the class time spent on cosmology topics and other instructional strategies used to teach cosmology. We used this combination of qualitative and quantitative research results to evaluate the conceptual understandings of students who used the new cosmology Lecture-Tutorials compared to those students who did not. The analysis of our data shows that, in many cases, classrooms that used the cosmology Lecture-Tutorials saw a greater increase in their students’ conceptual cosmology knowledge compared to classrooms that did not use the cosmology Lecture-Tutorials. However, our results also indicate how instructors implement the Lecture-Tutorials into their classrooms strongly influences their students’ learning gains. 相似文献

Mahalanobis distance (M-distance) case diagnostics are a useful tool for assessing response pattern inconsistency in factor analysis; however, the derivations of these statistics assume continuous variables, which limits their utility in ordinal self- or rater-report data. This research generalizes M-distance diagnostics to categorical factor analysis. We prove that the residual-based M-distance dr is equivalent to the person-fit index lco, which motivates the use of the new categorical M-distance dr* as a person-fit index. dr* is compared and contrasted with zh, a commonly used item response theory person-fit index. A simulation study is used to show that a simple transformation of dr* satisfies established criteria for person-fit measures. A sample of responses to the Rosenberg Self-Esteem Scale is used to determine parameters for a simulation study, and real data are analyzed to contrast the use of dr and dr* as indexes of person-fit in continuous and categorical factor analysis. 相似文献

This paper makes a contribution to the debate that has been described as a tension between instrumental and emancipatory educational objectives in environment and sustainability education. The contribution involves a methodological approach (introd-) using the concept ‘dislocatory moments’, to identify and analyse moments in classroom practice that address educational objectives relating to ‘change for sustainability’ and ‘thinking and acting independently’. A case of business education, when ‘sustainable development’ is integrated in a series of lessons, is used to exemplify the approach involving analysis of the emergence and closure of a dislocatory moment and the change of logics that occur. The illustrative case shows how room for subjectivity and change can be intertwined in educational practice. It is suggested that the methodological approach could be used in empirical research of classroom practice to further knowledge about the kind of situations that contribute to ‘business as un-usual’ without compromising emancipatory education ideals. 相似文献

While research has documented the key role of monitoring processes during hypermedia learning, limited empirical research
has used process data to examine the possibility that these processes mediate the relationship between motivational constructs
(such as self-efficacy) and cognitive factors (such as prior domain knowledge) with hypermedia learning outcomes. This multi-method
study addressed this issue by examining: (1) The extent to which the relationship between self-efficacy and hypermedia learning
outcomes is mediated by the use of specific monitoring processes and; (2) The extent to which the relationship between prior
domain knowledge and hypermedia learning outcomes is mediated by the use of specific monitoring processes. Participants included
68 education majors. A self-report questionnaire was used to measure self-efficacy, a pretest was used to measure prior domain
knowledge, a posttest was used to measure learning outcomes, and a think-aloud protocol were used to identify the deployment
of monitoring processes during a 30-min hypermedia learning task. Results indicated that the relationship between self-efficacy
and specific monitoring processes (Monitoring Understanding, Monitoring Environment, and Monitoring Progress Towards Goals) was significantly detectable. Additionally, the relationship between prior domain knowledge and Monitoring Understanding was significantly detectable. Lastly, regression analyses revealed that the relationship between self-efficacy and hypermedia
learning outcomes was mediated by the extent to which participants monitored their understanding and the environment. 相似文献

Three experiments examined 4‐ to 6‐year‐olds' use of potential cues to geographic background. In Experiment 1 (N = 72), 4‐ to 5‐year‐olds used a speaker's foreign accent to infer that they currently live far away, but 6‐year‐olds did not. In Experiment 2 (N = 72), children at all ages used accent to infer where a speaker was born. In both experiments, race played some role in children's geographic inferences. Finally, in Experiment 3 (N = 48), 6‐year‐olds used language to infer both where a speaker was born and where they currently live. These findings reveal critical differences across development in the ways that speaker characteristics are used as inferential cues to a speaker's geographic location and history. 相似文献

This paper challenges a view of concrete materials as artifacts used within a rigid instructional sequence that particular children are perceived to require or not, as the case may be. Focussing on mathematics teaching, it contends that it is more useful to consider the function of these materials as tools, artefacts used flexibly and selectively by pupils to make sense of mathematics, rather than as crutches, devices which may support procedural competency in mathematics but with no guarantees of understanding. 相似文献

The goal of this study was to investigate the usefulness of person‐fit analysis in validating student score inferences in a cognitive diagnostic assessment. In this study, a two‐stage procedure was used to evaluate person fit for a diagnostic test in the domain of statistical hypothesis testing. In the first stage, the person‐fit statistic, the hierarchy consistency index (HCI; Cui, 2007 ; Cui & Leighton, 2009 ), was used to identify the misfitting student item‐score vectors. In the second stage, students’ verbal reports were collected to provide additional information about students’ response processes so as to reveal the actual causes of misfits. This two‐stage procedure helped to identify the misfits of item‐score vectors to the cognitive model used in the design and analysis of the diagnostic test, and to discover the reasons of misfits so that students’ problem‐solving strategies were better understood and their performances were interpreted in a more meaningful way. 相似文献

Research shows that deaf children have inferior achievement in simple arithmetic compared to their hearing agemates. The reported study investigates whether the reasons for deaf children's poor achievement can be sought in their strategy development. As this is a central issue, the strategies used by deaf children when solving symbolic addition and subtraction problems are identified, classified and compared to findings from earlier research, involving both deaf and hearing children. The effect of Sign Language in strategy invention and use is the main concern in this study. One result from the present study is that structural aspects of Sign Language counting may influence deaf children's thinking in a way that does not lead to a developed conceptual knowledge base, but instead to refined procedural competence. This is a development in simple arithmetic that is compatible with that of less able hearing children. The counting procedures used by the deaf children involve both oral counting and Sign Language counting. Due to the small sample size, and the shortcomings of the research design, the results are more suggestive than conclusive. Thus, further studies are needed in this area.This revised version was published online in September 2005 with corrections to the Cover Date. 相似文献

This study investigated the manner in which 56 infant educators used language to direct the behaviour of infants (defined as children aged birth to two years), on the basis that the ways in which educators frame their commands represent an important component of young children’s learning experiences. Underpinned by systemic functional linguistic theory, the study analysed the frequency and type of command produced by educators with university, diploma and certificate qualifications. Suggestive and indirect commands convey a sense of negotiation, as if the addressees’ subjective opinions and thoughts are considered, while nonsuggestive and direct commands foreground the speakers’ power and authority. The findings demonstrate that commands feature frequently in educators’ talk to infants, with nonsuggestive and direct commands being most commonly used. Individual differences were related to the qualifications of staff. University-qualified early childhood teachers used significantly fewer nonsuggestive and direct commands than did diploma and certificate-qualified educators, and they were more likely to provide infants with a reason for the command. These findings have implications for the way in which learning opportunities are created by the language that educators use, and for the overall quality of infant early childhood programmes. 相似文献

The Keep It Simple package, which includes a short animated film (available online for streaming or download), a lesson plan, and supporting materials, was designed to be used with adolescents ages 15–19 to empower them to seek sexual and reproductive health care, and emphasize the availability of long-acting reversible contraception (LARCs). The materials in the package can be used together to deliver a 45 minute educational session that provides information to teens about the sexual health services available to them at local health centers, their rights to obtain those services, and how they can link to high quality and adolescent friendly sexual health care. The animation can also be used as a standalone product. All components of the Keep It Simple package are available for free and are also offered in Spanish as No te compliques. 相似文献

Aristotle discussed various forms of rationality in the Organon and other works. Aristotle held that in making judgments, the soul used five means— intelligence, episteme (scientific knowledge), sophia (theoretical wisdom), techne (art), and phronesis (practical wisdom). The nature of rhetoric as a techne employed in persuasion and grounded in probabilities distinguishes it from discourse in natural science, metaphysics, and philosophy. Aristotle's comparative study of the reasoning used by each of these means enables us to recognize rhetoric's uniqueness. 相似文献

Abstract This article examines the effectiveness of four elementary school math curricula: (a) Investigations in Number, Data, and Space; (b) Math Expressions; (c) Saxon Math; and (d) Scott Foresman–Addison Wesley Mathematics (SFAW). These curricula are distinct from one another and represent many of the diverse approaches used to teach elementary school math in the United States. The results are based on 39 schools that were randomly assigned to use the various curricula at the first-grade level. The results show that average spring first-grade math achievement of Math Expressions and Saxon students was 0.30 SD higher than Investigations students and 0.24 SD higher than SFAW students. These effect sizes mean that an average-performing student's percentile rank in math would be 9 to 12 points higher if the school used Math Expressions or Saxon, instead of Investigations or SFAW. We also conducted correlational analyses that examine whether curriculum-group differences in math instructional time and content coverage account for the differences in curriculum effects and found that a portion of the relative effects is due to differences in content coverage. 相似文献

Five high school biology textbooks were examined to determine the inclusion of four aspects of the nature of science: (a) science as a body of knowledge, (b) science as a way of investigating, (c) science as a way of thinking, and (d) science and its interactions with technology and society. The textbooks analyzed were BSCS Biology—A Human Approach (Kendall/Hunt), BSCS Biology—An Ecological Approach (Kendall/Hunt), Biology—The Dynamics of Life (Glencoe), Modern Biology (Holt), and Prentice Hall Biology (Prentice Hall). The same six chapters or sections were analyzed in each textbook, which were the methods of science, cells, heredity, DNA, evolution, and ecology. A scoring procedure was used that resulted, for the most part, in good intercoder agreement with Cohen’s kappa values ranging from 0.36–1.00. The five recently published biology textbooks in the United States have a better balance of presenting biology with respect to the four themes of science literacy used in this research than those analyzed 15 years ago, especially with regard to devoting more text to engaging students in finding out answers, gathering information, and learning how scientists go about their work. Therefore, these biology textbooks are incorporating national science education reform guides that recommend a more authentic view of the scientific enterprise than similar textbooks used 15 years ago. 相似文献

The author asserts that editors should publicly declare their expectations and expose the rationales for editorial policies to public scrutiny. He argues that editorial policies ought to require effect size reporting, as those at 17 journals now do. He also argues (a) that score reliabilities should be reported; (b) that stepwise methods should not be used; (c) that structure coefficients should be interpreted; and (d) that if used wisely, confidence intervals differ from hypothesis tests in important ways. The use of noncentral t and F distributions to create confidence intervals about effect sizes also is appealing. 相似文献

Organisations that provide education are businesses and, as such, are not immune from the impact that the Internet has had
in recent years, both on the way organisations conduct their business and as a business supporting technology. Indeed, the use of the Internet as a facilitating mechanism for educational course delivery
has been growing steadily over the last 5–8 years and, although there are some significant issues that have arisen in that
time in relation to the quality of learning that can be achieved, there is no doubt that it will continue to be developed
as an educational tool. The real issue for educators is, therefore, not whether the Internet will be used in course delivery, or if it is a useful tool, but rather how can a teacher make best use of it to enhance learning? This article documents a study that has analysed five years of student
reflections on the scaffolding mechanisms used to promote and encourage learning in five Internet-based courses at the University
of Queensland run between 2001 and 2005. The courses involved include three Internet-delivered Masters coursework courses
and two Internet-delivered undergraduate courses in three different discipline areas. The outcomes of the study are: (1) a
Report Card documenting student evaluations of the scaffolding mechanisms used; (2) a What, Why, How, Where framework of scaffolding
mechanisms that are best suited to enabling deep learning through the online environment, and (3) a proposed new model of
knowledge acquisition in online learning environments entitled ESCIE, which is based on Nonaka’s SECI and Ba models of knowledge
creation. 相似文献

This paper investigates whether or not lexical stress is used for lexical access in Spanish. A lexical decision task and a
masking priming procedure were used to compare correctly-versus-incorrectly stressed words (e.g., técla-TECLA vs. teclá-TECLA). SOA (Stimulus Onset Asynchrony) was manipulated at 33, 66, 100, and 143 ms. The results showed that congruent condition
was easier, but in 143 ms SOA only. Furthermore, while congruent condition did not differ from a control identity condition
(e.g., tecla-TECLA) incongruent condition was slower, but in 100 and 143 ms SOA only. All these results suggest that stress affects lexical
access at a late stage of lexical access processing. Reading models should be re-designed in order to include lexical stress
as another phonological code which is used for reading. 相似文献

The purpose of this study was to determine the proportion of empirical studies published in the last 5 years in a sample of special education peer‐reviewed journals that (1) assessed the effects of reading and math interventions with group designs and (2) used random assignment to treatment conditions to test those interventions. A hand search of articles from the Journal of Special Education, Exceptional Children, Learning Disabilities Research & Practice, the Journal of Learning Disabilities, and School Psychology Review yielded 806 relevant articles, of which 5.46 percent tested a reading or math intervention using a group design and 4.22 percent used random assignment. These findings indicate that randomized experimental designs, which offer the highest level of evidence of an intervention's efficacy, are underrepresented in the literature, at least in the area of reading and math interventions. 相似文献

Research Findings: In addition to being a regulatory strategy, children’s private speech may enhance or interfere with their effortful control used to regulate emotion. The goal of the current study was to investigate whether children’s private speech during a selective attention task moderated the relations of their effortful control to their anger and sadness. The private speech of 156 preschoolers (age in months: M = 52.10, SD = 9.24, min = 36.20, max = 69.50) was transcribed and coded during a selective attention task. Effortful control was observed and reported by parents. Anger and sadness were reported by parents and observed in a frustration task. Children who used more inaudible muttering had higher levels of sadness. Effortful control interacted with private speech to explain anger. The negative relation of effortful control to anger was significant for children who used low and moderate but not high levels of task-irrelevant private speech. Practice or Policy: The presence of private speech, although it may support regulatory abilities within a task, may be an additional form of evaluation that might help teachers and caregivers decide how best to support children’s learning. These findings suggest that private speech can be used as an indicator of how well children use other regulatory abilities, such as effortful control. 相似文献

Research Findings: This research examines preschoolers' use of mental state terms in naturally occurring peer conflicts in the classroom to determine how children use mental state terms for organizing their social interactions. Analyses focus on the types, frequencies, and social interactive functions of mental state terms. Utterances (N = 166) with mental state terms from 124 conflict episodes were analyzed. Children used a number of different mental state terms, want and need being the most frequently used, to index their own and their interlocutors' desires for subtle interactive purposes. Want was paired most often with bids for action, objects, inclusion in a play area, or clarification of another child's mental state. Need was most often used when directing the other child's action or attention, to justify, clarify, or insist on their own action or previous request. Practice or Policy: Findings suggest that children's peer conflicts constitute a rich setting for the active construction of social relationships through the use of utterances with mental state language. This emphasis on peer interactions has the potential to inform new ways of supporting children's self–other development as a foundation for academic success. 相似文献
