This study examined how types of tasks influenced student activities/thinking and defined the role of Seatwork in mathematics lessons. It used 60 lessons from the TIMSS videotaped Study. These data indicated that practice was the most prevalent form of tasks in the U.S. In Germany, students completed mathematical calculations after a complex problem-solving segment. In Japan, teachers combined practice of routine procedures in Seatwork with opportunities to prepare material, think about problems, and explore concepts. Findings expand our understanding of how tasks organize learning opportunities and effect how students come to understand mathematics. 相似文献

We develop a theory of human capital investment to study the effects of school quality on student choices of education, and to understand its effect on economic growth. In a dynamic general equilibrium closed economy, primary education is mandatory but there is an opportunity to continue to secondary education and beyond. High-quality education increases the returns to schooling, and hence the incentives to accumulate human capital. This is caused by two different channels: higher quality makes education accessible to more people (extensive margin), and once individuals decide to participate in higher education, higher-quality increases the investment made per individual (intensive margin). Furthermore, educational quality determines human capital composition and growth. Cross-country data evidence shows that the proposed channels are quantitatively important and that the effect of the quality and quantity of education on growth depends on the stage of development. 相似文献

The article presents a study on metalinguistic, cognitive and metacognitive abilities in university students. A sample of
353 students was recruited; 178 of which from scientific and 175 from humanistic Faculties, with gender balance (M = 178;
F = 175) whose age range was between 20 and 25 years old. They were administered a metalinguistic ability test that assesses
metalinguistic awareness at implicit and explicit levels (L and ML scores) and the Raven’s Standard Progressive Matrices 38
(SPM38). In addition to the usual nonverbal administration of the matrices, candidates were asked to justify in written form
the reasons for the solution indicated in each item. Three scores were considered for the SPM38: the ordinary score based
on the number of correct nonverbal solutions (O.S.), a 7-point scale for assessing the argumentation of the correct solutions
(C.ARG.S.) and a 6-point scale for assessing the argumentation of the incorrect solutions (I.ARG.S.). Significant gender and
curriculum effects were found, with males and scientific students dominating at the nonverbal level while females and humanistic
students dominated in the argumentative abilities related to the matrices and in all the scores of the metalinguistic test.
A number of significant correlations were found between all the metalinguistic, cognitive and metacognitive abilities considered,
with a prominent role of the metalinguistic abilities at the explicit level (ML score) that show a clear argumentative structure
very similar to the C.ARG.S. argumentations in the matrices test. 相似文献

This is a report of a study of students’ understanding of infinite series. It has a three-fold purpose: to show that students may construct two essentially different notions of infinite series, to show that one of the constructions is particularly difficult for students, and to examine the way in which these two different constructions may be built so that we may uncover ways to help students improve their understanding. The theoretical framework consists of action–process–object–schema theory and the specific model of conceptions in Balacheff’s theory of conception, knowing, and concept. Approaching the problem from these two different theoretical perspectives allows us to provide different and at the same time complementary explanations of observed phenomena. The two different infinite series constructions are, briefly stated, series as an infinite unending process of addition and series as a sequence of partial sums. Students are found to have difficulty building an understanding of series as a sequence of partial sums and thus tend to have difficulty in problem situations that require this interpretation. The study uses semi-structured interviews with 10 graduate students. The interviews explore situations that might give insight into students’ notion of the sequence of partial sums. 相似文献

AbstractWe analysed the editorial process of the four articles authored by junior researchers published in the special issue The peer review process as an opportunity for learning. Our aims were to study the unfolding of the main critiques and suggestions made by reviewers in the different review rounds, as well as to explore how both authors and reviewers experienced and valued the review process. Data sources include all review reports and letters where the authors explained the changes made, and questionnaires completed by all the authors and some reviewers. The most commonly identified critiques in the reports were related to content selection and elaboration (coherence and relevance), the own author’s voice (critical positioning and caution) and attention to the reader (precision and consistency in terms and concepts, methodological clarity, writing style, legibility and formal adequacy). All four authors stated that being part of this process was rewarding and educational, highlighting the development of academic writing skills. Some reviewers emphasized the importance of reading other reviewers’ reports. We conclude by emphasizing the importance of providing junior researchers with resources that support them in communicating their research to the academic community. 相似文献

In the framework of teacher’s approaches to teaching, this study investigates the relationship between student-related variables (i.e., study time, class absence, domain knowledge, and homework completion), students’ approaches to learning, and teachers’ approaches to teaching using structural equation modeling (SEM) with two independent data samples. The participants were 61 biology teachers and their corresponding 1,518 high school students (12th grade). The first sample was used to fit the model, and the second sample was used to analyze the consistency of the data derived from the first sample. Using a two-level SEM analysis, we established whether the effects found at the individual level varied significantly at class level. The students’ approaches to learning were related to the teachers’ approaches to teaching as a function of the hypotheses established in the model, although the effect size was smaller than expected. However, approximately 48 % of the variance of the surface approach and 46 % of the deep approach sat at class level. At the individual level, the results of this study suggest that students’ approaches to learning significantly explain their teachers’ approaches to teaching and, thus, constitute important contextual variables. At the class level, the way students learn appears to be closely associated with class-related variables. Our data stresses the importance of promoting educational opportunities (e.g., school-based courses) for teachers to reflect upon the teaching methodologies used in class. 相似文献

A random telephone survey (N = 255) of Washington state parents of children between the ages of 2 and 17 assesses parents’ reported patterns of interaction with their children regarding television, along with parental viewing habits and perceptions of television content. Demographic differences in mediation and coviewing patterns, as well as parental attitudes toward television, are explored, and explanations for these differences are considered. It is concluded that education is a weak predictor of mediation levels, single parents do not differ from dual parents in attitudes about television, and that the negative relationship of income to positive mediation and use of television as a babysitter is related more to overall viewing patterns and environmental constraints, rather than to attitudinal differences. It is suggested that demographics hold little value jar explaining why and how parents hold particular attitudes or engage in particular behaviors relevant to television and parenting. 相似文献
