Elementary Science Students’ Motivation and Learning Strategy Use: Constructivist Classroom Contextual Factors in a Life Science Laboratory and a Traditional Classroom     

Andrea R. Milner  Mark A. Templin  Charlene M. Czerniak 《Journal of Science Teacher Education》2011,22(2):151-170

The purpose of this study was to describe the influence of constructivist classroom contextual factors in a life science laboratory and a traditional science classroom on elementary students’ motivation and learning strategy use. The Constructivist Teaching Inventory was used to examine classroom contextual factors. The Motivated Strategies for Learning Questionnaire was used to examine student motivation and learning strategies. A Wilcoxon nonparametric test determined that constructivist teaching practices were found to occur more often in the life laboratory than in the regular classroom. Although constructivist teaching practices increased at each observation time in both the regular classroom and in the life laboratory, a Friedman test determined that they were not statistically significant increases. Paired sample t tests determined that student motivation and learning strategies were higher in the life laboratory than in the regular classroom overall as well as at each survey time except for learning strategies at Post 1. A 2 × 4 between 3 within repeated measure ANOVA determined that student MSLQ motivation and learning strategy scores in the regular classroom varied statistically significantly by teacher. Student MSLQ motivation and learning strategy scores in the life laboratory varied statistically significantly by teacher. To triangulate data, individual interviews of students were conducted at the end of the semester and revealed students regard the life laboratory as an asset to their science study; however, students do appreciate and value working in the learning environment that the regular classroom provides.  相似文献   

Are all citations worth the same? Valuing citations by the value of the citing items     

Cristiano Giuffrida  Giovanni Abramo  Ciriaco Andrea D’Angelo 《Journal of Informetrics》2019,13(2):500-514

Bibliometricians have long recurred to citation counts to measure the impact of publications on the advancement of science. However, since the earliest days of the field, some scholars have questioned whether all citations should be worth the same, and have gone on to weight them by a variety of factors. However sophisticated the operationalization of the measures, the methodologies used in weighting citations still present limits in their underlying assumptions. This work takes an alternative approach to resolving the underlying problem: the proposal is to value citations by the impact of the citing articles, regardless of the length of their reference list. As well as conceptualizing a new indicator of impact, the work illustrates its application to the 2004–2012 Italian scientific production indexed in the WoS. The proposed impact indicator is highly correlated to the traditional citation count, however the shifts observed between the two measures are frequent and the number of outliers not negligible. Moreover, the new indicator shows greater “sensitivity” when used to identify the highly-cited papers.  相似文献   

Testing for universality of Mendeley readership distributions     

Ciriaco Andrea D’Angelo  Samuele Di Russo 《Journal of Informetrics》2019,13(2):726-737

Altmetrics promise useful support for assessing the impact of scientific works, including beyond the scholarly community and with very limited citation windows. Unfortunately, altmetrics scores are currently available only for recent articles and cannot be used as covariates in predicting long term impact of publications. However, the study of their statistical properties is a subject of evident interest to scientometricians. Applying the same approaches used in the literature to assess the universality of citation distributions, the intention here is to test whether the universal distribution also holds for Mendeley readerships. Results of the analysis carried out on a sample of publications randomly extracted from the Web of Science confirm that readerships seem to share similar shapes across fields and can be rescaled to a common and universal form. Such rescaling results as not particularly effective on the right tails. In other regions, rescaling causes a good collapse of field specific distributions, even for very recent publications.  相似文献   

Doctoral students’ experiences of nondisclosure with their dissertation chair     

Ryan M. Cook  Rachel Crabtree  Corrine R. Sackett  Andrea Baylin  Jyotsana Sharma 《Counselor Education & Supervision》2023,62(1):64-79

We examined doctoral students’ experiences of nondisclosure with their dissertation chairs. Using a hermeneutic phenomenology design, we analyzed two individual interviews of 10 doctoral students. We identified the following three themes: (a) the professional dynamics in the relationship, (b) the interpersonal and cultural dynamics in the relationship, and (c) prioritization of completing the dissertation. Implications for doctoral students and dissertation chairs are discussed.  相似文献   

To Score or Not to Score: Factors Influencing Performance and Feasibility of Automatic Content Scoring of Text Responses     

Torsten Zesch  Andrea Horbach  Fabian Zehner 《Educational Measurement》2023,42(1):44-58

In this article, we systematize the factors influencing performance and feasibility of automatic content scoring methods for short text responses. We argue that performance (i.e., how well an automatic system agrees with human judgments) mainly depends on the linguistic variance seen in the responses and that this variance is indirectly influenced by other factors such as target population or input modality. Extending previous work, we distinguish conceptual, realization, and nonconformity variance, which are differentially impacted by the various factors. While conceptual variance relates to different concepts embedded in the text responses, realization variance refers to their diverse manifestation through natural language. Nonconformity variance is added by aberrant response behavior. Furthermore, besides its performance, the feasibility of using an automatic scoring system depends on external factors, such as ethical or computational constraints, which influence whether a system with a given performance is accepted by stakeholders. Our work provides (i) a framework for assessment practitioners to decide a priori whether automatic content scoring can be successfully applied in a given setup as well as (ii) new empirical findings and the integration of empirical findings from the literature on factors that influence automatic systems' performance.  相似文献   

School playgroups: Which features of provision matter?     

Susan Edwards  Karen McLean  Jacinta Bartlett  Andrea Nolan  Maria Evangelou  Michael Henderson  Helen Skouteris  Joanne Tarasuik 《British Educational Research Journal》2022,48(3):598-616

This paper identifies the shared features of provision in exemplar school playgroups defined using the social capital concepts of bonding and bridging relationships. Relationships promote capabilities amongst people, with play a known capability for advancing children's developmental and educational outcomes. By attending to the bonding and bridging relationships in each school playgroup, exemplar groups were identified and studied to reveal their shared features of provision. Six main features of provision were identified, including materials, facilitator, space, location, scheduling and health and safety. Awareness of these features may benefit school leaders and/or governance seeking to implement a school playgroup within their own community. Findings from this project suggest high-performing school playgroups can operate in areas of lower and higher socioeconomic status and/or parental education, and in regional and rural areas.  相似文献

Enhancing Anatomical Instruction: Impact of a Virtual Canine Anatomy Program on Student Outcomes     

Andrea Linton  Andrew C. Garrett  Kenneth R. Ivie Jr.  Jay D. Jones  Jason F. Martin  Jeremy J. Delcambre  Christianne Magee 《Anatomical sciences education》2022,15(2):330-340

Innovative reforms in medical education will require instructional tools to support these changes and to give students more flexibility in where and how they learn. At Colorado State University, the software program Virtual Canine Anatomy (VCA) was developed to assist student learning both inside and outside the anatomical laboratory. The program includes interactive anatomical photographs of dissected canine cadavers, dissection instructions with accompanying videos and diagrams, radiographs, and three-dimensional models. There is a need to evaluate the effectiveness of instructional tools like VCA so that decisions on pedagogical delivery can be evidence-based. To measure the impact of VCA on student outcomes in a dissection laboratory, this study compared student attitudes, quiz scores, dissection quality and accuracy, and instructor reliance between students with and without access to VCA. Students with VCA needed less time with teaching assistants (P < 0.01), asked teaching assistants fewer questions (P = 0.04), felt that the dissection was easier (P = 0.02), and were in stronger agreement that they had access to adequate resources (P = 0.02). No differences were found in the dissection quality or accuracy, quiz scores, or attitudes regarding overall enjoyment of the activity between the two groups. This study shows that VCA increases student independence and can be used to enhance anatomical instruction.  相似文献
