Abstract

This paper outlines the experience of a university professor who implemented flipped learning in two sections of college algebra courses for two semesters. It details how the courses were flipped, what technology was used, advantages, challenges, and results. It explains what students do outside of class, what they do inside class, and discusses what students thought of the course based on surveys and course evaluations. It also compares results on a similar final exam to those of a control group.  相似文献

The impact of misspecifying covariance matrices at the second and third levels of the three-level model is evaluated. Results indicate that ignoring existing covariance has no effect on the treatment effect estimate. In addition, the between-case variance estimates are unbiased when covariance is either modeled or ignored. If the research interest lies in the between-study variance estimate, including at least 30 studies is warranted. Modeling covariance does not result in less biased between-study variance estimates as the between-study covariance estimate is biased. When the research interest lies in the between-case covariance, the model including covariance results in unbiased between-case variance estimates. The three-level model appears to be less appropriate for estimating between-study variance if fewer than 30 studies are included.  相似文献

In educational environments, monitoring persons' progress over time may help teachers to evaluate the effectiveness of their teaching procedures. Electronic learning environments are increasingly being used as part of formal education and resulting datasets can be used to understand and to improve the environment. This study presents longitudinal models based on the item response theory (IRT) for measuring persons' ability within and between study sessions in data from web-based learning environments. Two empirical examples are used to illustrate the presented models. Results show that by incorporating time spent within- and between-study sessions into an IRT model; one is able to track changes in ability of a population of persons or for groups of persons at any time of the learning process.  相似文献

League tables that rank universities may use reputational measures, performance measures, or both. Each type of measure has strengths and weaknesses. In this paper, we rank disciplines in Australian universities both by reputation, using an international survey of senior academics, and with actual performance measures. We then compare the two types of measures to see how closely they match. The criterion we use for both sets of measures is ‘international academic standing’. We find a high correlation between the survey results and the various measures of research performance. We also find a correlation between the quality of student intake and the survey rankings, but the satisfaction levels of recent graduates do not correlate well with the rankings by academics. We then construct an overall measure of performance, which gives very similar rankings to the survey results, especially for the top-ranked institutions.

The relation is studied between teachers’ pedagogical content knowledge of reading and the quality of their subsequent classroom behaviour in teaching fluent reading. A confirmatory factor analysis model with two latent variables is tested and shows adequate goodness-of-fit indices. Contrary to our expectations, the results of structural equation modelling reveal a small but significant γ-value of .29, indicating that only 8% of the variance in teachers’ classroom behaviour in teaching fluent reading is accounted for by teachers’ pedagogical content knowledge of reading. Presumably teacher knowledge is not as stable and conclusive as one might think. More research is needed in determining the factors that work restricting for teachers in putting their knowledge into classroom practice. It is recommended that preservice and in-service teacher training should not be limited to transfer of knowledge, but should also assist teachers in designing and performing effective fluent reading instruction.  相似文献

High-fidelity anatomical models can be produced with three-dimensional (3D) scanning techniques and as such be digitally preserved, archived, and subsequently rendered through various media. Here, a novel methodology—digital body preservation—is presented for combining and matching scan geometry with radiographic imaging. The technique encompasses joining layers of 3D surface scans in an anatomical correct spatial relationship. To do so, a computed tomography (CT) volume is used as template to join and merge different surface scan geometries by means of nonrigid registration into a single environment. In addition, the use and applicability of the generated 3D models in digital learning modalities is presented. Finally, as computational expense is usually the main bottleneck in extended 3D applications, the influence of mesh simplification in combination with texture mapping on the quality of 3D models was investigated. The physical fidelity of the simplified meshes was evaluated in relation to their resolution and with respect to key anatomical features. Large- and medium-scale features were well preserved despite extensive 3D mesh simplification. Subtle fine-scale features, particular in curved areas demonstrated the major limitation to extensive mesh size reduction. Depending on the local topography, workable mesh sizes ranging from 10% to 3% of the original size could be obtained, making them usable in various learning applications and environments.  相似文献

The discovery of the electron in 1897 deeply impacted the nature of chemistry in the twentieth century. A revolution in the theoretical structure of chemistry as well as in the instrumental tools used in chemical analysis occurred as a result of this discovery. The impact of this revolution on tin oxide chemistry over approximately a 100 year period is the focus of this paper. Important questions addressed include the following: Are tin oxides of importance in our current society or are they only of quaint academic interest? In what way has chemistry as a discipline added to our understanding of the tin oxides and has this added any technological value to these compounds? Does the historical approach followed in this paper offer chemistry educators the opportunity to place current chemical knowledge in a broader epistemological framework? The impact of the answers to these questions on chemistry education is discussed.  相似文献

The strength of holistic face perception in children with autism spectrum disorder (ASD) was evaluated by applying the gaze‐contingent mask and window technique to a face matching and discrimination task in 6‐ to 14‐year‐old children with (= 36) and without ASD (= 47), and by examining fixation patterns. Behavioral results suggested a slower and less efficient face processing in the ASD sample compared with the matched control group. Comparing the moving mask and window conditions revealed a reduced holistic face processing bias in the younger age group but not in the older sample. Preferential viewing patterns revealed both similarities and differences between both participant groups.  相似文献
