The paper presents an alternative explanation for the pattern of relative difficulty of arithmetical word problems to that suggested by Riley et al. (1983). Their view is based on the assumption that all symbolic manipulations take place internally. It is argued that for many problems much of the manipulation is accomplished externally.  相似文献

In this study we examined the consistency of life-course child maltreatment trajectories and youth offending links across birth cohorts. In so doing we demonstrated the value of replication studies for maltreatment research. We applied the methodology of Stewart et al. (2008) and linked population-based (1990 birth cohort) child protection and youth justice administrative data from Queensland, Australia. We performed a group based trajectory analysis to identify distinct maltreatment trajectory groups distinguishable by maltreatment timing and frequency across the life-course. We explored group-based youth offending outcomes with consideration of variations in maltreatment chronicity, timing, and frequency, multi-type maltreatment, gender and race (Indigenous Australian versus non-Indigenous Australian youths). To determine the consistency of maltreatment trajectories and offending links across cohorts (1983/84 versus 1990) we compared our results with those of Stewart et al. (2008). Consistent with Stewart et al. (2008): (1) We identified six distinct maltreatment trajectory groups; (2) Trajectory groups characterised by chronic maltreatment and/or adolescent maltreatment had the largest proportion of young offenders; and (3) Maltreatment frequency commonly peaked at transition points. Extending beyond Stewart et al. (2008) we noted considerable overlap between maltreatment dimensions and a potential impact of race and multi-type maltreatment on maltreatment and offending links. We endorse replication studies as a valuable tool to advance child maltreatment policy and practice and recommend further research on interactions between maltreatment dimensions, gender, race, and youth offending.  相似文献

Motivation predicts academic achievement beyond cognitive ability. Expectancy value theory (Eccles et al., 1983) is a widely accepted and powerful approach explaining academic achievement as well as educational choices and attainment. Recently, attention to the multiplicative term of expectancy and value beliefs has increased. Trautwein et al. (2012) reported a detrimental effect of high task value when expectancy beliefs were low. We aimed to replicate and extend their study by using a large, representative sample of students attending upper secondary school in the German federal state Schleswig-Holstein (N = 3367). Following Trautwein et al. (2012), we applied latent interaction modelling to test whether the predictive value of expectancy value interactions differs for grades, final examinations, and standardized test scores as measures of achievement in two domains. We took the multi-dimensional structure of task value into consideration, analyzing the four components (attainment, intrinsic value, utility and cost) separately. Both a verbal and a non-verbal domain (English as a foreign language and mathematics) were investigated. Overall, the results supported those of Trautwein et al. (2012). However, our findings suggested measure- and domain-specific differences when using expectancy value beliefs and their interactions to predict academic achievement. Interaction terms predicted final examination results in both English and mathematics. Further, interaction effects were significant for grades in English but not mathematics. In general, effect sizes of multiplicative terms were small, especially in contrast to expectancy beliefs. Findings are discussed regarding the practical and conceptual importance of the multiplicative term in expectancy value theory applied in an educational setting.  相似文献

In most cultures, young people begin to think about plans for the future during adolescence. In particular, the question of career choice becomes especially salient. Among the various crises associated with adolescence in Western cultures, that of choosing a career has been singled out by some researchers as the most problematic developmental task facing youth (Grinder, 1975; Connell et al, 1975). Wish-fulfilling fantasies decline and realistic thinking about education and work increases (Lessing, 1968) and the development of the self is accompanied by developing views on the world of work (Pryor, 1983). In developing countries, it has been suggested that the level of development becomes a pressure on the career orientation of youth. For example, to the extent that certain sets of values defined as ‘modern’ are accepted, then the desire for upward mobility, consumerism and enhanced life-style become associated with educational and occupational criteria (Saha, 1981; Chang, 1983).  相似文献

Joe Wittmer and Thomas Sweeney, Executive Director and Chairperson, respectively, of the APGA Council for Accreditation of Counseling and Related Educational Programs, respond to the article, “Counselor Education and the Psychology of More” (Pipes, Buckhold, & Merrill, 1983), found elsewhere in this issue. The authors agree that Pipes et al. challenged the profession to examine the state of the art in counselor education, but that they seemed unaware of the rapidly moving changes occurring within the profession today.  相似文献

Students’ value beliefs tend to decrease across secondary school (Wigfield et al., 2015). However, previous studies did not differentiate between all the dimensions of task values defined by expectancy-value theory (Eccles et al., 1983). Therefore, this study evaluated an instrument for assessing multiple value dimensions across grade level and academic subjects and tested for differences between grade levels in these subjects. A total of 830 students from Grades 5 to 12 completed a questionnaire assessing their value beliefs in German, English, math, biology, and physics with 37 items each. The factor structure was shown to be invariant across academic subjects, grade levels, and gender. Generally, students in higher grades showed lower means on positive value facets and higher means on cost facets. However, the results varied substantially by facet and subject. Furthermore, stereotypical gender differences in value beliefs were found, and some of these differences increased with students’ grade level. The findings indicate that examining multiple dimensions and subjects is crucial for developing a complete understanding of the development of students’ value beliefs.  相似文献

From classifications of word problems in international discussion of elementary mathematics instruction as well as from conceptual elaborations of didactical analyses in Germany, a classification of semantic structures of one-step word problems involving multiplication or division is proposed, comprehending four main classes: Forming the n-th multiple of measurers, combinatorial multiplication, composition of operators, and multiplication by formula. This classification is more comprehensive and differentiated than the classifications of Vergnaud (1983), Nesher (1988), and Bellet al. (1989) — aiming at a better assignment between diverse contextual circumstances and conceptual demands of mathematics and at compatibility with the well-known semantic structures of addition and subtraction word problems.  相似文献

The concept map is becoming a ubiquitous tool in education. In recent years there has been a growing interest in “diagramming” or “mapping” ideas to be learned (e.g., Jonassen et al., 1998). The approach has been championed by study skills proponents such as Buzan (1993). Maps of concepts and relationships have been used by many researchers and practitioners to help diagnose misunderstanding, improve study methods and glimpse how learners come to know. In other areas, the representation of knowledge in formalisms such as the Net greatly assisted the development of intelligent tutoring systems (e.g., Sowa, 1983). In order to better understand the claims made for its efficacy, reference to how concept maps have been used and defined will lead to a plausible explanation of the process of “off–loading” of concepts during learning or study (McAleese, 1994, 1998). In order to demonstrate the widespread application of supporting learn ers with external “learning spaces” (c.f. ISLEs/ and REALs—Grabinger et al., 1998; Grabinger & Dunlap, 1995; MacFarlane, 1993), consideration will be given in this paper to techniques that formally represent knowledge in Concept–Relationship–Concept “instances” (Fisher et al., 1990). Other techniques such as reflection journals draw on the same process but are not considered in detail here. The importance of self regulation (Zimmerman, 1990) and self-confrontation (McAleese, 1985) is highlighted in this framework. The map as a mirror or an assistant to learners is well documented (e.g., Vizcarro & Leon, 1998); the question of an external representation of thinking, in the form of a map determining what can be learned as well as what might be learned, is not yet fully known.  相似文献

Little, Bovaird and Widaman (2006) proposed an unconstrained approach with residual centering for estimating latent interaction effects as an alternative to the mean-centered approach proposed by Marsh, Wen, and Hau (2004, 2006). Little et al. also differed from Marsh et al. in the number of indicators used to infer the latent interaction factor and how they were represented, but this issue is separate from the mean versus residual centering distinction that was their primary focus. However, their implementation of the Marsh et al. mean-centered approach failed to incorporate the mean structure that Marsh et al. argued was necessary to obtain unbiased estimates. One might suppose that their new approach would suffer this same problem, an issue not addressed by Little et al. However, we demonstrate here why the Little et al. approach obviates this requirement that heretofore was thought to be necessary for all constrained, partially constrained, and unconstrained approaches. Both the Marsh et al. and Little et al. unconstrained approaches typically result in similar results and are much easier to implement than traditional constrained approaches. They differ primarily in that the Little et al. approach is a 2-step approach involving a potentially large number of separate analyses prior to estimating the structural equation model that apparently does not require the estimation of a mean structure, whereas the Marsh et al. approach is a 1-step approach that includes a mean structure.  相似文献

After reviewing the uses made of concept maps in research, as an aid to instruction and as a form of assessment, the problems of scoring maps objectively are discussed. Maps created de novo by 15‐16 year‐old pupils, before and after their introduction to Mendelian genetics, are used to investigate the properties of a scoring system based on that developed by Novak et al. (1983). The maps have been scored separately for a number of features ('branching’, ‘general to specific’, ‘closed units’, ‘terminology’, ‘relationships’ and ‘ hierarchy ‘) and compared with performance on genetics examination‐type questions. The components are not all independent, and do not have strong relationships with performance. The limitations of analytic methods of scoring concept maps are discussed.  相似文献

I consider Eccles et al.'s (1983) expectancy-value model of achievement performance and choice from a developmental perspective, by examining how recent research on the development of young children's competence beliefs, expectancies for success, subjective task values, and achievement goals can be incorporated into the model. The kinds of change in children's achievement beliefs considered include change in the factor structure of children's competence beliefs and values; change across age in the mean level of those constructs; and change in children's conceptions of ability beliefs and subjective values. I also discuss how achievement goals are conceptualized in this model, and how goals are conceived by other current motivation researchers. Changes in the nature of relations among competence beliefs, subjective task values, achievement goals, and achievement behaviors also are considered.  相似文献

Potentials for empowerment in critical education research   总被引：1，自引：0，他引：1  
Within the typology of research orientations commonly represented in the social science literature — empiricist, interpretive and critical — it is the methodologies of the critical orientation that are burgeoning. Significantly, the moral imperative in the critical theorising which drives and shapes these methodologies is empowerment and emancipation. That is to say, critical educational research is potentially empowering because of its emancipatory intent. However, as cogently argued and demonstrated by a number of researchers, “an emancipatory intent is no guarantee of an emancipatory outcome” (Acker et al., 1983: 431). Just being informed by critical theory then, is no guarantee that a critical research approach will be empowering, or be empowering in a way we recognise as significant. This paper has been prepared with two objectives in mind: to clarify three ways empowerment has been conceptualised in the literature, and to use this conceptual scheme as a template to ascertain the empowerment potentials in critical educational research methodologies.  相似文献

Developing scientific literacy about water systems is critical for K-12 students. However, even with opportunities to build knowledge about the hydrosphere in elementary classrooms, early learners may struggle to understand the water cycle (Forbes et al., 2015 ; Gunckel et al., 2012 ; Zangori et al., 2015 ; Zangori et al., 2017 ). Scientific modeling affords opportunities for students to develop representations, make their ideas visible, and generate model-based explanations for complex natural systems like the water cycle. This study describes a comprehensive evaluation of a 5-year, design-based research project focused on the development, implementation, revision, and testing of an enhanced, model-centered version of the Full Option Science System (FOSS) Water (2005) unit in third grade classrooms. Here, we build upon our previous work (Forbes et al., 2015 a; b; Vo et al., 2015 ; Zangori et al., 2015 ; Zangori et al., 2017 ) by conducting a comparative analysis of student outcomes in two sets of classrooms: (1) one implementing the modeling-enhanced version of the FOSS Water unit developed by the research team (n = 6), and 2) another using the standard, unmodified version of the same curricular unit (n = 5). Results demonstrate that teachers in both conditions implemented the two versions of the curriculum with relative fidelity. On average, students exposed to the modeling-enhanced version of the curriculum showed greater gains in their model-based explanations for the hydrosphere. Engagement in scientific modeling allowed students to articulate hydrologic phenomena by (1) identifying various elements that constitute the hydrosphere, (2) describing how these elements influenced the movement of water in the hydrosphere, and (3) demonstrating underlying processes that govern the movement of water in the hydrosphere.  相似文献

This study examined the effects of gratitude journaling on first-year college students’ adjustment, life satisfaction, and positive affect. Students who scored high (i.e., scores between 35 and 56) on the Perceived Stress Scale (Cohen et al. in Journal of Health and Social Behavior, 24, 385–396, 1983) and low (i.e., scores between 48 and 144) on the University Life Scale (Alada? et al. in Türk Psikolojik Dan??ma ve Rehberlik Dergisi, 2(20), 41–47, 2003) were invited to participate in the study. Among the 24 students who met the criteria, 21 volunteered to participate. Students in the experimental group (11) kept a gratitude journal for 3 weeks, whilst those in the control group (10) were not involved in any gratitude-related activity. Results indicated that students in the experimental group had significantly higher post-test scores on gratitude, adjustment to university life, life satisfaction, and positive affect. Results related to gratitude interventions, positive emotions and college student adjustment are discussed.  相似文献

Since the controversial finding of the Coleman Report (1966), which was that school resources had little effect on educational outcomes comparing to family background, huge literature has emerged in order to verify the above finding in countries other than the United States. The Heyneman–Loxley work (1983) presented for the first time clear evidence that variation in school resource quality could matter more than variation in family inputs in low and middle income countries. Following this literature, and using TIMSS 2007 data, we attempt in this study to revisit the Heyneman–Loxley hypothesis and the related debate regarding the overall importance of schools in explaining variations in student achievement across Middle East and North African countries. Survey Jackknife regression technique and quantile regressions have been used for the purpose of this study. Our results are in line with those of Baker et al. (2002) showing that the Heyneman–Loxley effect had declined over time.  相似文献

The purpose of this paper is to familiarize instructional designers and researchers with a useful design and research paradigm known as “Ask Systems.” Ask Systems are interrogative interfaces to information and learning environments that model conversations with a skilled, reflective practitioner (Sch?n, The reflective practitioner, 1983) or teacher. By selecting questions to answer, users access information or scaffolds that help them to solve a problem, perform a task, or comprehend domain knowledge. Ask Systems are potentially effective for designing interactive learning systems because question asking is one of the most fundamental skills in learning that affects comprehension and problem solving (Graesser et al., in: Britton and Graesser (eds.) Models of understanding text, 1996b; Graesser et al., Journal of Artificial Intelligence in Education, 3:235–241, 1992). By selecting questions to answer, students may also learn how to generate their own meaningful questions, because the quality of student-generated questions is strong predictor of domain knowledge and problem solving (Graesser and Olde, Journal of Educational Psychology, 95(3):524–536, 2003). Ask Systems are demonstrated that represent a variety of learning and task structures, including frequently asked questions, problem solving, metacognition, causal understanding, and multiple perspectives. Although empirical research on Ask Systems is very limited, they appear to represent a potentially effective paradigm for designing instruction and conducting research in a variety of learning environments.  相似文献

ABSTRACT

Results of two studies of children's competence beliefs and achievement values for mathematics and reading are summarized. Approximately 1700 children and adolescents participated in the studies; the participants were in first through 12th grades. The studies were based on an expectancy — value model of achievement choice proposed by Eccles et al. (1983). Results indicated that children's competence beliefs and achievement task values are distinctive belief systems, even in first grade children. During the elementary school years, the strength of relations between children's competence beliefs and adult evaluations of children's competence increased across grade. Children and adolescents’ competence beliefs predict their mathematics performance, whereas their task values predict their intentions to continue taking mathematics.  相似文献
