Given the increased globalization and popularization of computer applications, translating a system's human interface into the local language has become a major consideration for software vendors and distributors. In this paper, we suggest a theoretical framework for the study of user interface translation. The framework includes recognizing vendors' and users' costs of, and benefits from, software translation. An experiment was conducted, based on this framework, to test user performance and preferences regarding interface translations. The experiment manipulated the translation of two interface components: documentation language and manipulation language. The results indicate that users are sensitive to different combinations of interface translation in a way that is commensurate with the instruction-following process (Terwilliger and Polson 1997). Users performed best when a fully translated interface was used and worst when only the manipulation language was translated. Users' preferences were in line with their performance, indicating that a cost benefit approach can serve as a promising starting point to the study of interface translation.  相似文献

It is difficult to examine the effectiveness of technology-based courses (TBC) without understanding the design and application in classrooms. There is evidence of disconnects among the theory for designing, the theory used to apply TBCs in classrooms, and the theory used to research and evaluate TBCs [Hickey, D. T. (1997). Motivation and contemporary socio-constructivist instructional perspectives. Educational Psychologist, 32(3), 175–193]. Comments provided by administrators, teachers and students may lead researchers to determine whether or not the original TBC course goals have been attained. In this paper, we first discuss examples of theoretical disconnects found in other technology-based research [Aleven, V. E., Stahl, E., Schworm, S., Fischer, F., & Wallace, R. (2003). Help seeking and help design in interactive learning environments. Review of Educational Research, 73(3), 277–320; Hickey, D. T., & McCaslin, M. (2001). A comparative, sociocultural analysis of context and motivation. In S. Volet, & S. Järvelä (Eds.), Motivation in learning contexts: Theoretical advances and methodological implications (pp. 33–55). Elmsford, NY: Pergamon Press]. Then, we describe the course design of the mathematics TBC used in this study, the reasons the principal and the teacher’s believe the software will benefit their mathematics students, and the perceptions of mathematics students regarding the effectiveness of the technology in their classroom. In conclusion, we will discuss how this preliminary qualitative data shaped our future research questions.  相似文献

Scientific research involves mathematical modelling in the context of an interactive balance between theory, experiment and computation. However, computational methods and tools are still far from being appropriately integrated in the high school and university curricula in science and mathematics. In this paper, it is discussed the relevance of mathematical modelling and illustrated how a computer modelling tool (Modellus, a free tool available on the Internet and developed at FCTUNL) can be used to embed modelling in high school and undergraduate courses. Modellus allows students to create and explore mathematical models using functions, differential and iterative equations, and visualize the behaviour of mathematical objects.  相似文献

Two cycles of design-based research of a cognitive tool (CT) for teaching fractions have been completed. Following the success of a quasi-experimental study of the enhanced CT derived from the second cycle of design-based research, this article reports the findings of a pre-test–post-test control group empirical study using the enhanced CT in the classroom. The results indicate that there were no statistically significant differences in learning outcomes between the exploratory learning approach, using the CT, and the traditional direct teaching approach. The CT enabled students to generate a procedural knowledge of adding and subtracting fractions with like and unlike denominators through an exploratory learning process. Teachers asserted that the CT was effective for stimulating reciprocal tutoring among students, and students were enthusiastic about using the CT as an educational tool. Hence, the CT has potential for further development as a tool for promoting collaborative learning in the classroom.  相似文献

This study investigated the effects of the spatial contiguity principle within computer-based instruction (CBI) of group personalized two-step mathematics word problems on the achievement and attitude of 98 sixth-grade predominantly Hispanic students. Students were randomly blocked by ability level based on their pretest scores to a spatially contiguous or non-spatially contiguous version of the CBI. The results revealed students who received the spatially contiguous treatment made significantly greater pretest-to-posttest gains than students who received the non-spatially contiguous treatment. In addition, lower-ability students made significantly greater pretest-to-posttest gains than higher-ability students. Findings from the student attitude survey revealed no significant difference in treatment responses to the two survey factors on CBI Satisfaction and Attitude About Math. Student comments from the open-ended questions on the attitude survey and the focus group interview indicated that the spatially contiguous version of the CBI was more helpful and less confusing than the non-spatially contiguous version.  相似文献

There is an increasing recognition in the society that interdisciplinary challenges must be part of new educational practices. In this paper, we describe the key curriculum activities at the University of Southern Denmark that combine mathematical modelling, software engineering, and user-centred design courses. These three disciplines represent a core of our graduate program, aiming at educating the professionals that will be capable of not only using but also further developing new technologies, and therefore, will be capable of fostering further the progress in computational science and engineering. Finally, we show how the learning environment, with emphases on broadening the student experience by industrial links, affects the student career aspiration.  相似文献

Abstract This paper considers the role of school programming using the BOXER environment. It gives details of a two-year research project in which a group of primary school children (aged 9 - 11) developed their understanding of number through programming in BOXER. It argues that such programming should be regarded as a new form of literacy and as such, developed in concert with subject knowledge, and evaluated over the whole of schooling.  相似文献

Abstract  This paper considers some results of a study designed to investigate the kinds of mathematical activity undertaken by children (aged between 8 and 11) as they learned to program in LOGO. A model of learning modes is proposed, which attempts to describe the ways in which children used and acquired understanding of the programming/mathematical concepts involved. The remainder of the paper is concerned with discussing the validity and limitations of the model, and its implications for further research and curriculum development.  相似文献

This paper reports on the findings of the evaluation of Learning Units (LU), a special type of Learning Object designed to help overcome the difficulties associated with learning Calculus concepts at undergraduate level. An Interactive Platform for Learning Calculus (PIAC) that serves as a container for the LU was created following a specific instructional design, namely, the Teaching Unit Model (TUM), which in turn, rules the platform's design, development and implementation. A general perspective on the development of the platform and its LU is presented, including the results of usability and functionality evaluations, which indicate that the platform and the LU comply with different functionality and usability criteria which are fundamental for their introduction into formal university courses. The platform was utilized in a higher education Calculus course, and its effects on different aspects of the learning process were studied. Two experimental groups and two control groups for a total of 102 students taking the Calculus course participated in the study. Results indicated an overall acceptance of using PIAC in class. Important evidence was obtained on the positive effects of using PIAC, not only influencing academic performance of students, but also in motivational aspects of the learning process. The grades obtained in all of academic activities by the groups using PIAC, compared with the control groups, provide solid evidence to the positive influence of the intervention of the technology under the TUM.  相似文献

Critical user interface design features of computer-assisted instruction programs in mathematics for students with learning disabilities and corresponding implementation guidelines were identified in this study. Based on the identified features and guidelines, a multimedia computer-assisted instruction program, ‘Math Explorer’, which delivers addition and subtraction word problem-solving instruction for students with learning disabilities at the early elementary level, was designed and developed. Lastly, usability testing was conducted to assess whether Math Explorer was well-designed in terms of the interface for students with learning disabilities. Given the results of the usability testing, this study corroborated the fact that the critical user interface design features and guidelines in mathematics computer-assisted instruction programs would be essential for facilitating the mathematical learning of students with learning disabilities. Implications for practice and future research were discussed.  相似文献
