A Study on Human-Computer Interaction Mechanism in an Intelligent Tutoring System     

GAO Hongli  YANG Lei  XU Sheng  LONG Zhou  LIU Kai  HU Xiang’en 《Frontiers of Education in China》2022,17(1):100

Discussion is a common and important learning process. Involvement of a virtual agent can provide adaptive support for the discussion process. Argumentative knowledge construction is beneficial to learners’ acquisition of knowledge,but the effectiveness of argumentative scaffolding in existing studies is not consistent. Based on an intelligent discussion system, a total of 47 undergraduate students took part in the experiment and they were assigned to three different conditions: content-related plus content-independent scaffolding condition, content-related scaffolding condition, and the control condition. Under the content-related and content-independent scaffolding condition, the computer agent provided an idea from semantically different categories (content-related scaffolding) according to the automatic categorization of the current contributions, and further inquired the participants about their attitudes and reasons (content-independent scaffolding). Under the condition of content-related scaffolding condition, the virtual agent only provided semantically different viewpoints. Under the control condition, the subjects expressed their opinion independently without the participation of the virtual agent. Findings revealed that compared with the control group, when the virtual agent provided semantically different ideas (content-related scaffolding), the discussion breadth (number of categories) was improved and the subjects felt that they had a more comprehensive understanding of the problem. Compared with the content-related scaffolding condition, when the virtual agent provided semantically different ideas and further asked about the attitudes and reasons, the subjects expressed more agreement with these views, but mentioned fewer categories during the discussion. This study suggests that the content-related scaffolding can facilitate the cognitive processing effect relevant to the topic of discussion. When the content independent scaffolding is added, it can promote the argumentative processing, but may have a negative effect on the cognitive processing related to the topic discussed.  相似文献   

On the relation between the degree of internationalization of cited and citing publications: A field level analysis,including and excluding self-citations     

Giovanni Abramo  Ciriaco Andrea D’Angelo  Flavia Di Costa 《Journal of Informetrics》2021,15(1):101101

The growing complexity of scientific challenges demands increasingly intense research collaboration, both domestic and international. The resulting trend affects not only the modes of producing new knowledge, but also the way it is disseminated within scientific communities. This paper analyses the relationship between the “degree of internationalization” of a country’s scientific production and that of the relevant citing publications. The empirical analysis is based on 2010-2012 Italian publications. Findings show: i) the probability of being cited increases with the degree of internationalization of the research team; ii) totally domestic research teams tend to cite to a greater extent totally domestic publications; iii) vice versa, publications resulting from international collaborations tend to be more cited by totally foreign publications rather than by publications including domestic authors. These results emerge both at overall and at discipline level. Findings might inform research policies geared towards internationalization.  相似文献   

Designing Reading Comprehension Assessments for Reading Interventions: How a Theoretically Motivated Assessment Can Serve as an Outcome Measure     

Tenaha O’Reilly  Jonathan Weeks  John Sabatini  Laura Halderman  Jonathan Steinberg 《Educational Psychology Review》2014,26(3):403-424

When designing a reading intervention, researchers and educators face a number of challenges related to the focus, intensity, and duration of the intervention. In this paper, we argue there is another fundamental challenge—the nature of the reading outcome measures used to evaluate the intervention. Many interventions fail to demonstrate significant improvements on standardized measures of reading comprehension. Although there are a number of reasons to explain this phenomenon, an important one to consider is misalignment between the nature of the outcome assessment and the targets of the intervention. In this study, we present data on three theoretically driven summative reading assessments that were developed in consultation with a research and evaluation team conducting an intervention study. The reading intervention, Reading Apprenticeship, involved instructing teachers to use disciplinary strategies in three domains: literature, history, and science. Factor analyses and other psychometric analyses on data from over 12,000 high school students revealed the assessments had adequate reliability, moderate correlations with state reading test scores and measures of background knowledge, a large general reading factor, and some preliminary evidence for separate, smaller factors specific to each form. In this paper, we describe the empirical work that motivated the assessments, the aims of the intervention, and the process used to develop the new assessments. Implications for intervention and assessment are discussed.  相似文献   

Using interactive management to facilitate a student-centred conceptualisation of critical thinking: a case study     

Christopher P. Dwyer  Michael J. Hogan  Owen M. Harney  John O’Reilly 《Educational technology research and development : ETR & D》2014,62(6):687-709

Critical thinking (CT) is a metacognitive process, consisting of a number of sub-skills and dispositions, that, when used appropriately, increases the chances of producing a logical solution to a problem or a valid conclusion to an argument. CT has been identified as a fundamental learning objective of third-level education; however, students often report not being given the opportunity to adequately understand and cultivate CT skills. Though most CT interventions are designed based on academic or expert definitions of CT skills, students are rarely, if ever, asked to guide their instruction by describing their perspectives on what constitutes CT. The current case study investigated students’ conceptualisations of what constitutes good CT using a collective intelligence methodology, interactive management. Interactive management (IM) is a computer-assisted process that allows a group to build a structural model describing relations between elements in a system. Though decades of research on group decision-making in educational and social psychology highlight the many limitations associated with group problem solving (e.g. as a result of an over-reliance on heuristics, cognitive biases and ‘groupthink’), a fundamental skill for making decisions and solving problems is the ability to collectively visualise the structure of a shared problem, and use this knowledge to design solutions and strategies for collective action. Results of IM group work from the current case study revealed five core CT skills (clarity of expression, conversational skill, inference, evaluation, and explanation), five CT dispositions (detachment, listening, systematicity, recognising uncertainty, and self-questioning) and fourteen structural relationships among them. The ability to detach, listen and engage in conversation with others, were seen as fundamental drivers of all other competencies in the system. Results are discussed in light of research and theory on CT and best practice for CT instruction.  相似文献   

Student teachers’ mathematics attitudes,authentic investigations and use of metacognitive tools     

Karoline Afamasaga-Fuata’i  Lumaava Sooaemalelagi 《Journal of Mathematics Teacher Education》2014,17(4):331-368

Based on findings from a semester-long study, this article examines the development of Samoan prospective teachers’ mathematical understandings and mathematics attitudes when investigating authentic contexts and applying working mathematically processes, mental computations and problem-solving strategies to find solutions of problems. The prospective teachers had enrolled for the second time (having failed their first attempt), in the first-year mathematics methods course of a 2-year Diploma of Education (Primary) programme. The group also included those enrolled in the Diploma of Education (Early Childhood and Special Needs) programmes, who recognizing their own limited understanding of mathematics would ordinarily shy away from opportunities for improvement. Given the negative mathematical and learning experiences, this group was ideal to engage in innovative and creative approaches that would make mathematics learning more meaningful and contextual in a Samoan environment. Only data from the attitudinal questionnaires and interviews are presented in this article. Main findings have implications for teaching and learning mathematics.  相似文献   

MODELING RELATIONSHIPS AMONG LEARNING,ATTITUDE, SELF-PERCEPTION,AND SCIENCE ACHIEVEMENT FOR GRADE 8 SAUDI STUDENTS     

M’HAMED TIGHEZZA 《International Journal of Science and Mathematics Education》2014,12(4):721-740

The purpose of the present study was to examine the validity of modeling science achievement in terms of 3 social psychological variables (school connectedness, science attitude, and active learning) and 2 self-perception variables (self-confidence and science value). Two models were tested: full mediation and partial mediation. In the full-mediation model, effects of the 3 social psychological variables upon science achievement were hypothesized to be completely mediated through science value and self-confidence. In the partial-mediation model, however, those 3 variables were hypothesized to affect achievement directly as well as indirectly through the mediating roles of science value and self-confidence. Data were obtained from Grade 8 Saudi students (N = 4,099) who participated in TIMSS 2007. The relationships among constructs were examined with the use of structural equation modeling software Mplus7. Results indicated that both models performed adequately in terms of fit indices, but the partial-mediation model was retained due to its superiority over the full-mediation model in representing the sample covariance matrix as tested through chi-square difference test. The mediating role of self-confidence in the relationships of science attitude and active learning to achievement was substantiated, but the mediating role of science value was not supported.  相似文献

Asymptotic behavior of solutions of some semilinear functional differential and integro-differential equations with infinite delay in Banach spaces     

A. Caicedo  C. Cuevas  G.M. Mophou  G.M. N’Guérékata 《Journal of The Franklin Institute》2012,349(1):1-24

We prove in this paper the existence and uniqueness of mild solutions to some functional differential and functional integro-differential equations with infinite delay in Banach spaces which approach almost automorphic functions at infinity. We also discuss the existence of S-asymptotically $\omega \text{-}\mathrm{periodic}$ mild solutions. The results are new.  相似文献
