Exploring the parallelism between change in students' conceptions and historical change in the concept of inertia

This study investigates students' conceptions of inertia and compares these conceptions with historical change in the concept. A total of 736 students from four different age groups (i.e., age 11, 13, 15 and 17) participated in the survey. Questions in the questionnaire represent problems related to the concept of inertia which have been argued by past scientists such as Aristotle, Buridan, Galileo, and Newton. The questionnaire contained three questions, each concerned with one of the following applications of inertia: natural motion, the motion of a flying spear, and the falling motion of a stone on a moving ship. The results of the survey showed that there were considerable similarities as well as dissimilarities between students' conceptions and the views of past scientists. It is suggested that this kind of comparison studies would give useful background information on change in students' conceptions. To this day every student of elementary physics has to struggle with the same errors and misconceptions which then had to be overcome, and on a reduced scale, in the teaching of this branch of knowledge in schools, history repeats itself every year.

Learning design to support student-AI collaboration: perspectives of leading teachers for AI in education

Education and Information Technologies - Preparing students to collaborate with AI remains a challenging goal. As AI technologies are new to K-12 schools, there is a lack of studies that inform how...     

Lessons of love: Psychoanalysis and teacher-student love

What is the relation of love and pedagogy? Two recent phenomena have called into question whether love has any place within pedagogy at all: teacher‐student sexual scandal and the standardization movement. As love walks the thin line between inspiration and sex, and as standardization has assumed love to be synonymous with bias, it has become more important than ever to provide a clear account of love and its relation to teaching. For this account, I turn to Lacanian psychoanalysis and, in particular, to Lacan's contentious claim that “There is no such thing as a sexual relationship.” Through an explication of Lacan's position on love, I conclude that love not only has a place within pedagogy but is necessary for it.     

Exploring teaching concerns and characteristics of graduate teaching assistants

The purpose of the study was to explore a conceptual structure of graduate teaching assistant (GTA) teaching concerns. Results indicated that GTAs experience five distinct, inter-related types of concerns: class control, external evaluation, task, impact and role/time/communication. These ‘teaching concerns’ were further analysed by examining their relationship with the value placed on them by the GTAs and the confidence in dealing with the teaching-related issues of concern. The results revealed that GTAs tend to have concerns about self, task or role/time/communication-related issues when the nature of the concerned issues is perceived as being valuable but challenging. On the other hand, GTAs are more likely to have concerns with impact-related issues when the nature of the issues is perceived as both being valuable and manageable. Several GTA characteristics, such as teaching experience, teacher efficacy, participation in professional development and values on teaching practices, were examined as predictors of GTA teaching concerns.     

The Rate and Delay in Overload: An Investigation of Communication Overload and Channel Synchronicity on Identification and Job Satisfaction

This study investigates the relationship between communication overload and uses of diverse communication channels in terms of their level of synchronicity. Emphasis on the synchronicity of any given channel reveals how temporal elements (i.e., rate and processing time) play an important role in perceptions of communication load. Additionally, this study examines the association between communication overload, organizational identification and job satisfaction. Findings reveal: (a) both high and low synchronous channels are associated with increased reports of communication overload; (b) a mediating effect of organizational identification on the relationship between communication overload and job satisfaction; and (c) a moderating effect of communication overload on the relationship between low synchronous channels and organizational identification.     

Television,Gender Norms,and Tanning Attitudes and Intentions of Young Men and Women

This study investigated whether and how exposure to tanned images on television is related to tanning attitudes and intentions among men and women, using the influence of presumed influence model (Gunther & Storey, 2003 Gunther , A. C. , & Storey , J. D. ( 2003 ). The Influence of presumed influence . Journal of Communication , 53 , 199 – 215 .[Crossref], [Web of Science ®] , [Google Scholar]). The model showed a better fit with the male rather than female sample. In addition, among males, exposure to tanned-men images on television was directly associated with protanning attitudes and was indirectly associated with protanning intentions. Corresponding direct and indirect associations were not found among females. Instead, the results suggest females may project their own protanning intentions into the estimation of protanning norms among male and female peers. These results suggest the social perceptual processes underlying the link between television exposure and tanning tendencies of men and women may differ.     

Coding and Centering of Time in Latent Curve Models in the Presence of Interindividual Time Heterogeneity

The coding of time in latent curve models has been shown to have important implications in the interpretation of growth parameters. Centering time is often done to improve interpretation but may have consequences for estimated parameters. This article studies the effects of coding and centering time when there is interindividual heterogeneity in time such as when longitudinal responses are dependent on a point of origin that varies between individuals. Using representative examples that differ in their degree of interindividual time heterogeneity, we compare different models based on alternative forms of coding and centering of time to evaluate potential for biased estimates. Recommendations are made for studies marked by heterogeneity in time measures.     

Named entity recognition with multiple segment representations

Named entity recognition (NER) is mostly formalized as a sequence labeling problem in which segments of named entities are represented by label sequences. Although a considerable effort has been made to investigate sophisticated features that encode textual characteristics of named entities (e.g. PEOPLE, LOCATION, etc.), little attention has been paid to segment representations (SRs) for multi-token named entities (e.g. the IOB2 notation). In this paper, we investigate the effects of different SRs on NER tasks, and propose a feature generation method using multiple SRs. The proposed method allows a model to exploit not only highly discriminative features of complex SRs but also robust features of simple SRs against the data sparseness problem. Since it incorporates different SRs as feature functions of Conditional Random Fields (CRFs), we can use the well-established procedure for training. In addition, the tagging speed of a model integrating multiple SRs can be accelerated equivalent to that of a model using only the most complex SR of the integrated model. Experimental results demonstrate that incorporating multiple SRs into a single model improves the performance and the stability of NER. We also provide the detailed analysis of the results.     

Differential Influences of Family Processes for Scientifically Talented Individuals' Academic Achievement Along Developmental Stages

Differential influences of various family processes for students of science talent and students in general education from Grades 4 to 12 and Science Olympians in Korea were examined by administering Korean Inventory of Parental Influence. Korean Science Olympians were additionally interviewed about their family and school experiences. Family processes were perceived more frequently or more strongly by scientifically talented students and younger students than general-education students and older students, respectively. Supportive and conducive family processes were maintained even in the high-school period in the families of scientifically talented students, whereas they decreased as students in general education get older. Father's involvement emerged as the most influential predictor of mathematics and science achievement, whereas press for intellectual development was a significant predictor for grade-point average (GPA). Parents may need to maintain the conducive and supportive family processes even for their high-school children in order to nurture their talents in mathematics and science.
