Recent increased interest in computational thinking poses an important question to researchers: What are the best ways to teach fundamental computing concepts to students? Visualization is suggested as one way of supporting student learning. This mixed-method study aimed to (i) examine the effect of instruction in which students constructed visualizations on students’ programming achievement and students’ attitudes toward computer programming, and (ii) explore how this kind of instruction supports students’ learning according to their self-reported experiences in the course. The study was conducted with 58 pre-service teachers who were enrolled in their second programming class. They expect to teach information technology and computing-related courses at the primary and secondary levels. An embedded experimental model was utilized as a research design. Students in the experimental group were given instruction that required students to construct visualizations related to sorting, whereas students in the control group viewed pre-made visualizations. After the instructional intervention, eight students from each group were selected for semi-structured interviews. The results showed that the intervention based on visualization construction resulted in significantly better acquisition of sorting concepts. However, there was no significant difference between the groups with respect to students’ attitudes toward computer programming. Qualitative data analysis indicated that students in the experimental group constructed necessary abstractions through their engagement in visualization construction activities. The authors of this study argue that the students’ active engagement in the visualization construction activities explains only one side of students’ success. The other side can be explained through the instructional approach, constructionism in this case, used to design instruction. The conclusions and implications of this study can be used by researchers and instructors dealing with computational thinking.  相似文献

Abstract

The European Higher Education Area has promoted reconsidering the role played by teachers at universities. Faculties are expected to design learning activities that promote the acquisition of competencies among students. In this context, technologies have garnered prominence as they contribute to creating student-centred learning environments. This study answers these research questions: (1) To what extent has university teaching changed with the implementation of digital technologies in university classrooms? What technology-based learning activities are incorporated in instructional designs by the teachers? (2) How does the faculty describe the integration of technological knowledge into pedagogical content knowledge when designing and developing technology-based learning activities? (3) According to university teachers, which other factors (intrinsic or extrinsic) determine the use of digital technologies in their learning designs? To answer these questions, we have collected data from two differentiated samples of university teachers using the Inventory of Learning Activities with Technology at the University and semi-structured interviews. First, the results reveal that teachers use technologies to carry out learning activities focusing on the content and the teacher. Student-centred learning activities are only timidly being incorporated. Second, the extent to which such activities are implemented is linked to the teachers’ techno-pedagogical content knowledge. Third, the factors that facilitate or inhibit teachers from using technologies in the teaching–learning process respond to intrinsic aspects, such as teachers’ knowledge and beliefs, but also to extrinsic and contextual issues, such as the discipline taught or institutional policy at the university regarding the use of educational technologies.  相似文献

Traditional structures in higher education support a separation between faculty members’ and students’ perspectives on classroom practice. This is in part because student-faculty interactions are typically defined by a focus on content coverage and by a clear delineation between faculty and student roles in engaging that content. This paper focuses on key findings from an ongoing action research study that aims to address these basic questions: (1) What happens when faculty and students engage in structured dialogue with one another about teaching and learning outside of the regular spaces within which they interact? and (2) How can such dialogic engagement become a part of both students’ and teachers’ practice? The study takes place within the context of a program that supports undergraduate students and college faculty members in semester-long partnerships through which they explore teaching and learning. The goal of these explorations is to examine, affirm, and, where appropriate, revise pedagogical practice. Constant comparison/grounded theory was used to analyze discussions among and feedback from participants. It was found that partnership facilitates both faculty and students multiplying their perspectives in ways that have the potential to improve teaching and learning. Participants consistently describe gaining new insights produced at and by the intersections of their experiences and angles of vision. Furthermore, they discuss how these insights deepen their own self-awareness and their understanding of others’ experiences and perspectives. Finally, they indicate that, as a result of gaining these insights and deepening their awareness, they are inclined to embrace more engaged and collaborative approaches to teaching and learning.  相似文献

This one semester case study intended to explore the roles of the instructor and students in design activities based on project based learning via cloud computing technology. Participants were 13 pre-service computer teachers enrolled in an internet programming course at faculty of education. Online course records, interviews and questionnaires were used to collect data. The data were analyzed via qualitative techniques. Results suggested that cloud computing facilitates planning, collaboration, and communication and also supports individual learning in online project based design activities. The instructor exhibited the roles of guidance, technical support, administrate and communicate. Students’ roles were found as cooperation, coordination, communication, leadership, practice, effort provide in project based activities. The results are hoped to provide insights about the roles of the instructor and students in online project based design activities. Along with the study findings, some implications were discussed for using cloud computing effectively in project based learning.  相似文献

Flipped classrooms continue to grow in popularity across all levels of education. Following this pedagogical trend, the present study aimed to enhance the face-to-face instruction in flipped classrooms with the use of clickers. A game-like clicker application was implemented through a bring your own device (BYOD) model to gamify classroom dynamics in the spirit of question-and-answer competitions. A series of flipped learning lessons were created for the study, with clickers integrated into question-and-answer activities associated with each of the lessons as formative assessments to assist students in the learning of English as a foreign language. In this quasi-experimental research, the data were gathered using a summative assessment, a perception survey, and individual interviews. The collected data were then analyzed to compare the students’ flipped learning experiences, with or without clicker use. The results indicated that the gamified use of clickers had positive influences on student learning, with regard to their performance, perceptions, and preferences. This study thus suggests that the emerging generation of clicker technology allows for a cost-effective BYOD integration model in flipped classrooms, through which it is possible to seamlessly bridge pre-class and in-class activities and to effectively promote student learning.  相似文献

Food science researchers have pronounced the Institute of Food Technologists Success Skills to be the most important competency mastered by graduates entering the work force. Much of the content and outcomes of the Success Skills pertains to oral communication skills of public speaking and interpersonal and group communication. This qualitative study reports the results of an examination of oral communication activities in the classes of 9 faculty in the food science program at Iowa State Univ. The findings revealed communication activities in the classes that support the Success Skills oral communication mandates; however, the food science faculty did not explicitly teach these skills. Faculty assumed the students would acquire proficiency in oral communication through participation in disciplinary activities that required them to practice the skills. A situated communication framework cautions communication researchers to honor the oral communication traditions in other disciplines. Still, the practice of preparing students to communicate in professional contexts without formal instruction raises 2 questions from the perspective of a communication researcher: first, are students aware of the communication skills they applied in classroom activities? Second, are students able to transfer communication skills to other classes and, more importantly to professional practice, when they graduate, as a result of this approach? The discussion suggests exercises that direct students’ attention to the specific skill sets inherent in the oral communication activities in the Success Skills while enabling faculty to maintain the communication traditions of food science as they prepare students for professional practice.  相似文献

This study investigated high school students’ conceptions of technology-assisted science learning via drawing analysis, and explored how students with different degrees of computer experience and science learning self-efficacy may show different conceptions via their drawings. The participants included 335 senior high school students in Taiwan (179 male and 156 female). All of them were asked by guiding questions to make two drawings to represent their conceptions of technology-assisted science learning in actual and ideal contexts, respectively. Their background information including computer experience and science learning self-efficacy were obtained using self-reported questionnaires. Through drawing analysis, seven categories of conceptions of technology-assisted science learning were identified, including types of technology, location of learning, types of learning activities, content of learning, participants of learning activities, affordance of learning technology, and effects of learning technology. The results further revealed that the students’ conceptions of actual and ideal technology-assisted science learning significantly differed in some sub-categories of all categories except the category of participants of learning activities. Moreover, students’ computer experience and science learning self-efficacy may link to different conceptions of technology-assisted science learning. Future research and directions are also discussed.

This qualitative case study at a two-year community college investigated the reasons behind a persistent gap in the college students’ engagement level in several key areas such as active and collaborative learning and student-faculty interaction as demonstrated in the longitudinal Community College Survey of Student Engagement (CCSSE) and the Community College Faculty Survey of Student Engagement (CCFSSE) results. Using the maximal variation purposeful sampling method, 63 students participated in the study. Results suggested that students’ own perception and behaviors, faculty’s expectations and characteristics, the course characteristics, and institutional level support all played an important role in engaging students. There was a disparity between students’ high perception of the importance of engagement and low level of effort and a disparity between faculty’s perception of student engagement and students’ own perception of engagement. Community college students welcomed high expectations and high standards from their faculty and also desired more challenging courses despite all the obstacles in their lives. Discussions and recommendations for strategies to close the gap in the two disparities and, thus, improve student engagement level are provided.  相似文献

Do students learn to model OR/MS problems better by using computer‐based interactive tutorials and, if so, does increased interactivity in the tutorials lead to better learning? In order to determine the effect of different levels of interactivity on student learning, we used screen capture technology to design interactive support materials for modeling and solving the transportation problem in a spreadsheet. A controlled experiment was carried out and the results indicate a general support for the effectiveness of interactive tutorials in enhancing students’ learning of modeling concepts. However, the study also found that excessive interactivity increased the cognitive load for the students and hindered their learning by making it difficult for them to consolidate concepts, integrate previous knowledge, and create meaningful mental models of the process.  相似文献

Abstract

Deans and directors of education in the United States are being asked to position their schools, colleges and departments of education (SCDE) for teaching and learning in the twenty-first century. A key question related to this effort is ‘How is the unit going to utilize current and emerging technologies as an integral part of their planning for instructional and managerial problems? ’ If deans and directors are to answer this question in an innovative way, at least two things must happen. First, they must understand their role as institutional technology leaders. Second, they must engage faculty, staff, and students in the careful exploration of three critical questions: 1. How does the SCDE create and maintain a technology infrastructure to support innovative instruction and program delivery? 2. How can the SCDE prepare faculty, staff, and students to teach and learn in a connected learning environment? And, 3. How best can the SCDE deliver programs in this new environment? This article describes why deans and directors must be leaders if technology is to be a part of the renewal process, discusses the issues related to each of the three questions, and provides a series of questions for deans and directors to stimulate discussion and planning efforts  相似文献

The coupling of the traditional classroom instruction and a virtual learning environment (VLE) in an engineering course is critical to stimulating the learning process and to encouraging students to develop competencies outside of the classroom. This can be achieved through planned activities and the use of information and communication technologies (ICTs), resources designed to complement students’ autonomous learning needs. A quantitative analysis of students’ academic performance using final course grades was performed for a fundamentals of electronics course and we examine students’ perception of their autonomy using surveys. The students’ progress and attitudes were monitored over four consecutive semesters. The first began with the design of the intervention and the following three consisted in the implementation. The strategy was focused on the development of course competencies through autonomous learning with ICT tools presented in the VLE. Findings indicate that the students who did the activities in the VLE showed an increase in performance scores in comparison with students who did not do them. The strategy used in this study, which enhanced perceived autonomy, was associated with a positive effect on their learning process. This research shows that a technology-enhanced course supported by ICT activities can both improve academic performance and foster autonomy in students.  相似文献

The purpose of this study was to examine how 1:1 laptop initiative affected student learning at a selected rural Midwestern high school. A total of 105 high school students enrolled in 10th–12th grades during the 2008–2009 school year participated in the study. A survey instrument created by the Mitchell Institute was modified and used to collect data on student perceptions and faculty perceptions of the impact of 1:1 laptop computing on student learning and instructional integration of technology in education. Study findings suggest that integration of 1:1 laptop computing positively impacts student academic engagement and student learning. Therefore, there is need for teachers to implement appropriate computing practices to enhance student learning. Additionally, teachers need to collaborate with their students to learn and understand various instructional technology applications beyond basic Internet browsing and word processing.  相似文献

The Preparing Tomorrow’s Teachers to Use Technology (PT3) initiative has funded various efforts to improve and enhance the technology preparation of preservice teachers. At Arizona State University, these efforts have focused on providing preservice teachers with opportunities to develop, implement, and evaluate their own instructional activities that utilize technology effectively and appropriately in authentic situations, to give them the myriad of tools necessary to integrate technology into teaching and learning activities. This paper focuses on the integration of these efforts into the field-based elementary education program, and discusses our formative evaluation of the field-based technology integration model, through the following questions: What are the preliminary successes of the model with regard to student perceptions, attitudes, and integration of technology into instructional activities? and What components of the model require additions or modifications?  相似文献

STEM教育注重通过跨学科的协作学习发展学生的知识和技能。近年来,计算机支持的协作学习(CSCL)被广泛应用于STEM教育。然而,其效果如何?其采用的各类技术和教学策略对学习效果有何影响?上述问题的明确有助于完善STEM教育中跨学科的协作学习设计。基于对2009至2019年间发表在国际期刊上的142项相关实验和准实验研究成果的元分析发现:在STEM教育中应用CSCL整体上有助于提升学习效果,且相较于过程类和情感类,其对认知类学习效果的作用最为明显;从学科来看,其对科学、工程学和教育学的影响相对较大;从采用的技术来看,通信技术、动态呈现技术和共享共建技术对学习效果的影响更加显著;从教学策略来看,案例式、游戏化、知识建构和探究式等教学策略更能提升学习效果。因此,在将CSCL应用于STEM教育时,应当加强针对情感类目标的设计以激发高水平的认知活动和认知成果,注重发挥共享共建类技术在知识可视化表征、知识追踪等方面的作用,通过整合多种教学策略推进协作探究学习。  相似文献

We investigated differences between field-study classrooms and traditional science classrooms in terms of the learning environment and students’ attitudes to science, as well as the differential effectiveness of field-study classrooms for students differing in sex and English proficiency. A modified version of selected scales from the What Is Happening In this Class? questionnaire was used to assess the learning environment, whereas students’ attitudes were assessed with a shortened version of a scale from the Test of Science Related Attitudes. A sample of 765 grade 5 students from 17 schools responded to the learning environment and attitude scales in terms of both their traditional science classrooms and classrooms at a field-study centre in Florida. Large effect sizes supported the effectiveness of the field-studies classroom in terms of both the learning environment and student attitudes. Relative to the home school science class, the field-study class was considerably more effective for students with limited English proficiency than for native English speakers.  相似文献

Many of the innovations that show promise for improving outcomes for underprepared community college students require instructors to make changes to their teaching practice. Little research explores the experiences of faculty teaching in reformed courses as related to their professional learning needs. Drawing on a multi-year qualitative study, this paper uses data from 100 faculty interviews to explore the questions they ask when teaching a new course. A key outcome of the analysis is a typology of questions that mirrors the stage of implementation. Through analysis of 20 observations of implementation activities, this paper also documents the learning opportunities made available to instructors and examines the extent to which these activities addressed their questions.  相似文献

The present study investigates the contribution of first language (L1) reading ability and second or foreign language (L2) proficiency to L2 reading comprehension, by focusing on the compensation between L1 reading ability and L2 proficiency. Two research questions were addressed: (1) does high L1 reading ability compensate for low L2 language proficiency? (2) does high L2 language proficiency compensate for low L1 reading ability? Participants were 241 Japanese university students learning English as a foreign language. They were divided into three levels (high, middle, low) according to the levels of their L1 reading ability and L2 language proficiency. Effects of these two factors on L2 reading ability were analysed by analysis of variance. A multiple regression analysis to estimate a compensation model was also applied. Results provided positive answers to both research questions. The present study thus demonstrates the mutual compensation between L1 reading ability and L2 proficiency, which works in order to achieve the highest possible level of L2 reading comprehension for readers with different ability backgrounds in L1 reading and L2 proficiency.  相似文献
