This paper describes a regression approach to experimental design. Typically, the educational researcher is familiar with the usual analysis of variance techniques and is unaware of the versatility of multiple regression for problem solving. The specific approach used in this paper assumes only a familiarity with experimental design and access to a general purpose multiple regression program which is likely to be on hand at any computer installation. Examples of the t-test, 1-way analysis of variance, and the treatment X subjects design from a regression standpoint are given. 相似文献

This study reports the results of a componential analysis of items comprising Sections A and C of Form Z of the reading comprehension portions of the California Achievement Tests (CAT) (Tiegs & Clark, 1963). A set of problem components or attributes characterizing the test items in terms of manifest content, psychologically salient features, and processing demands was developed, including methods for their quantification. The contributions of these components to task difficulty were then evaluated using linear regression methodology. Item difficulty indices were transformations of the familiar proportion-correct item score, obtained from data gathered during the spring of 1989 from 158 deaf examinees. Variation in the item difficulty values was substantially accounted for in terms of a small number of predictor variables (R2 greater than or equal to .90). Implications of the results for construct validity and interpretation of test scores are discussed. 相似文献

Educational psychology has a tradition of considering learning and motivation in terms of the individual and individual functioning. Short-term intervention studies have been common and quantitative measurement of the causes and effects of variables has been the aim of much research. When a sociocultural approach forms the basis of research into psychological constructs, a reappraisal of the research aims and the ways in which data are gathered and analysed is necessary. If the underlying assumption is that learning and motivation are socially and culturally situated, the design of research studies needs to encompass participation in authentic and purposeful activities. In order to develop a rich sociocultural understanding of these constructs, qualitative research designs become increasingly important. In this article, we consider two current research projects, one focusing upon conceptual change amongst students in a first year university class, and the other a classroom-based qualitative study exploring primary (elementary) students’ interest in learning. In each project, data have been collected over time in relation to both social interaction and individual functioning in specific sociocultural contexts. Our frameworks for data collection and approaches to data analysis are discussed in this article, together with some of the issues which we have identified as problematic. In particular we are conscious of the difficulties associated with articulating and describing the nature of social and cultural contexts, especially those with which we are familiar, and of distinguishing their most salient features. We are also critically aware that because our research is situated within very familiar environments, we need to identify and explore our implicit assumptions about those environments and the ways in which our roles as teachers and researchers both coincide and occasionally conflict. 相似文献

This research investigated how children interpret the meaning of a new word associated with a familiar artifact. The existing literature has shown that syntactic form-class information plays an important role in making this kind of inference. However, this information is not available to Japanese children, because Japanese language does not have a grammatical distinction between count nouns and mass nouns, proper nouns and common nouns, or singular and plural. In Study 1, 12 three-year-old monolingual Japanese children were tested to examine whether they interpreted a new noun associated with a familiar artifact to be a material name or a new label for the object. They interpreted the new word as a new category label for the object, rather than as a name for the material. How children related the new category to the old familiar one was then examined in Studies 2 and 3. The results of Study 2, in which 24 three-year-olds participated, showed that children could flexibly shift between two interpretations using shape information. When the named object had a typical shape for the familiar category, they mapped the new word to a subordinate category. In contrast, when the shape of the named object was atypical, they mapped the new word to a new category that was mutually exclusive to the familiar category by excluding the named object from the familiar category. In Study 3, 12 three-year-olds were tested to examine relative importance of shape and functional information in this inference process. The results of the three studies suggest that children flexibly recruit clues from multiple sources, but the cluesare weighed in hierarchical order so that they can determine the single most plausible solution in a given situation when different clues suggest different solutions. 相似文献

This article extends the LISREL model to incorporate fixed covariates at both the measurement and the structural equations of the model. A Bayesian procedure with conjugate type prior distributions is established. The joint Bayesian estimates of the latent variables and the structural parameters that involve the regression coefficients of the covariates, the variances, covariances and causations among the manifest and latent variables are obtained via the Gibbs sampler algorithm. It is shown that the conditional distributions required in the Gibbs sampler are familiar distributions, hence the algorithm is very efficient. A goodness of fit statistic for assessing the proposed model is presented. An illustrative example with some real data is presented. 相似文献

The study documents what deaf education teachers know about discrete mathematics topics and determines if these topics are present in the mathematics curriculum. Survey data were collected from 290 mathematics teachers at center and public school programs serving a minimum of 120 students with hearing loss, grades K-8 or K-12, in the United States. Findings indicate that deaf education teachers are familiar with many discrete mathematics topics but do not include them in instruction because they consider the concepts too complicated for their students. Also, regardless of familiarity level, deaf education teachers are not familiar with discrete mathematics terminology; nor is their mathematics teaching structured to provide opportunities to apply the real-world-oriented activities used in discrete mathematics instruction. Findings emphasize the need for higher expectations of students with hearing loss, and for reform in mathematics curriculum and instruction within deaf education. 相似文献

Children under 21 /2 years old tend to interpret novel words in accordance with the Mutual Exclusivity Principle, but tend not to reinterpret familiar words this way. Because alternative principle have been proposed that only predict the novel word effects, and because tests of the familiar word effects may have been flawed, a new test was administered. In Experiment 1 ( N = 32), 24- to 25-month-olds heard stories in which a novel noun was used for an atypical exemplar of a familiar noun. When asked to select exemplars of the familiar noun, they showed a small but reliable tendency to avoid the object from the story. In Experiment 2 ( N = 16), the novel nouns in the stories were replaced by pronouns and proper names, and the children did not avoid the story object in the test of the familiar noun. Thus, the aversion to this object that was observed in Experiment I was not due to its greater exposure or its being referenced immediately before testing, but to toddlers' Mutual Exclusivity bias. Their bias is hypothesized to be a form of implicit probabilistic knowledge that derives from the competitive nature of category retrieval. 相似文献

By designing effective learning opportunities for older adults, educators can make a positive contribution to the problem of a “graying America.” Because older adults themselves may offer important insights on what helps and hinders their learning, this qualitative study explored the perceptions of 36 older learners on effective and ineffective learning experiences. The following are the main findings that emerged from the data: (a) effective learning experiences are involving, (b) the instructor is a key component in the classroom, and (c) familiar or relevant topics are interesting. Recommendations for designing, marketing, and delivering quality learning experiences for older adults are discussed. 相似文献

Missing data is endemic in much educational research. However, practices such as step-wise regression common in the educational research literature have been shown to be dangerous when significant data are missing, and multiple imputation (MI) is generally recommended by statisticians. In this paper, we provide a review of these advances and their implications for educational research. We illustrate the issues with an educational, longitudinal survey in which missing data was significant, but for which we were able to collect much of these missing data through subsequent data collection. We thus compare methods, that is, step-wise regression (basically ignoring the missing data) and MI models, with the model from the actual enhanced sample. The value of MI is discussed and the risks involved in ignoring missing data are considered. Implications for research practice are discussed. 相似文献

This paper provides introductory statistics instructors with the capacity to use engaging National Basketball Association (NBA) data within a web application to either strengthen students' understanding or introduce the concept of variance and one-way analysis of variance. Using engaging data within the classroom provides context to data that students deem applicable to their lives. This paper not only provides a lesson plan for teaching these concepts but also provides a web application and the engaging NBA dataset if the instructor decides to use the app or the data in another context. The NBA data selected to focus on the debate “Who is the greatest NBA player of all time?”. By using context students are familiar with and interested in, we can get them interested in and further engaged in statistics. 相似文献

Psychologists studying developmental processes and sociologists studying social change developed sequential designs to enhance our ability to interpret change-related phenomena. Many educational researchers are also concerned with partitioning variance associated with change. Given the increased data-based capabilities of educational institutions, educational researchers should have more opportunities to use sequential designs. To this end, this paper illustrates how to analyze educational data from a cohort-sequential design. University data pertaining to grade inflation were analyzed using a variant of multiple regression. 相似文献

Unobservable properties that are specific to individuals, such as their proper names, can only be known by people who are familiar with those individuals. Do young children utilize this “familiarity principle” when learning language? Experiment 1 tested whether forty-eight 2- to 4-year-old children were able to determine the referent of a proper name such as “Jessie” based on the knowledge that the speaker was familiar with one individual but unfamiliar with the other. Even 2-year-olds successfully identified Jessie as the individual with whom the speaker was familiar. Experiment 2 examined whether children appreciate this principle at a general level, as do adults, or whether this knowledge may be specific to certain word-learning situations. To test this, forty-eight 3- to 5-year-old children were given the converse of the task in Experiment 1—they were asked to determine the individual with whom the speaker was familiar based on the speaker’s knowledge of an individual’s proper name. Only 5-year-olds reliably succeeded at this task, suggesting that a general understanding of the familiarity principle is a relatively late developmental accomplishment. 相似文献

The topic of social structure and interaction presents social science professors with a notable teaching opportunity. The active learning technique described in this article requires students to briefly analyze the statuses and roles of individuals with whom they are familiar. They then role play assigned characters as they would interact at a party. Through this activity, students learn to identify behaviors and characteristics that are appropriate for their relevant statuses. Statistical analyses, comparing students who took part in this activity to those exposed to a traditional lesson on the topic, indicated that the active learning exercise presented course information effectively and in an entertaining fashion. 相似文献

We explore the effectiveness of repeating the student-teacher match on test scores, for the universe of 8th graders in Chile using information on all student-teacher matches across multiple subjects and years, and a national, anonymous measure of test scores. Using a fixed effect and a regression discontinuity approach, we find that repeating matches has a robust positive effect on test scores. We show that this positive effect aggregates up to the student, class, and school-level, and also has longer-term effects on university admission exams. As channels, we find a significant positive effect on attendance, progression, student behaviour and teacher expectations. Reallocating teachers to classes with which they are familiar appears to offer a feasible strategy to improve student performance at low cost. 相似文献

Familiarity with learning contexts is important in the field of mobile-assisted language learning (MALL). Several review studies on MALL have been published to date. However, scholars have not covered certain aspects of familiar contexts in their reviews, such as which learning/instructional methodologies support learning in familiar contexts or what the affordances of familiar contexts are for language learning. To address this gap, the authors in this study reviewed research articles related to MALL in familiar, authentic environments published in the past 10 years. The reviewed articles were from journals published in the Social Science Citation Index between 2009 and 2018. The main aim of this study was to review the published articles to understand (1) pedagogical approaches, (2) data collection, (3) locations, (4) affordances of authentic environments and (5) issues in MALL research. The results revealed that the most frequent items in reviewed articles were task-based learning and communicative language teaching (pedagogical approaches); questionnaires, pretest and posttests and interviews (data collection); the local community and campus (locations); daily encounters, language learning and cognitive load (affordances of authentic environments); and small sample sizes and short-term interventions (issues in MALL research). Based on the results, the authors in this study made several suggestions and provided implications for educators and researchers in the field about MALL in familiar, authentic environments. 相似文献

Academic literacies research has been identified as an emerging but significant field in higher education. This article extends the discussions around methodology in academic literacies research by drawing on the current text and context debates in sociolinguistics and linguistic ethnography. It uses illustrations from a recent academic literacies research project to reflect on methodology and to emphasise the importance of a prolonged engagement with participants’ writing practices and experiences as well as the collection and analysis of a range of types of data to allow the researcher to become more familiar with the context. Methods such as allowing students to interpret their own writing, classroom observation and students’ written literacy histories gave the researcher real insights into the way students made connections to their own familiar contexts in order to learn. The research also highlighted the manner in which communication between students and teaching staff can break down because teachers misinterpret student utterances when they do not understand or know the contexts that the students are drawing on. At the same time, however, the researcher sounds some caution about the use of dialogue in ethnographic methodologies because communication is a two-way process and allocation of linguistic resources has been unequal. Therefore, where students’ resources do not match the context, they may struggle to communicate with the interviewer and to interpret their written texts. In these cases, interviewees who are first language speakers from privileged schooling backgrounds may be able to contextualise and interpret their writing more fully than interviewees who are speakers of English as a second or foreign language and who come from poorer rural schools. 相似文献
