This study investigated the effects of the use of augmented reality (AR) technologies in science laboratories on university students' laboratory skills and attitudes towards laboratories. A quasi-experimental pre-test/post-test control group design was employed. The participants were 76 first-year university students, aged 18–20 years old. They were assigned to either an experimental or a control group. Qualitative and quantitative data collection tools were used. The experimental results obtained following the 5-week application revealed that the AR technology significantly enhanced the development of the university students' laboratory skills. AR technology both improved the students’ laboratory skills and helped them to build positive attitudes towards physics laboratories. The statements of the students and the instructor regarding other effects of AR technology on science laboratories, both negative and positive, are also discussed. 相似文献

E-portfolios show great promise for supporting students' writing performance and facilitating peer feedback, but empirical research of their use in primary education is limited. To address this gap, a yearlong study was conducted in a 4th grade primary class in Cyprus implementing e-portfolios (n = 20) to help students document their progress and send feedback to peers. A generic, open source weblog tool localized into Greek was used as an e-portfolio tool. Data sources included 176 student-essays, 1306 instances of peer feedback, students pre- and post-tests on writing performance, nine videotaped student interviews and one teacher interview. A paired samples t-test analysis showed that there was a statistically significant difference between students' pre-test (M = 62.6, SD = 9.82, n = 20) and post-test (M = 76.5, SD = 12.6, n = 20) on writing performance (t (19) = −8.03, p < .01). A repeated measures analysis of variance on e-portfolio artifacts showed that there were learning gains with respect to students' writing performance over time [F(4.01, 76.25) = 31.59, p < .01, η2 = 0.89]. A qualitative analysis of students' comments showed that students provided more thorough peer feedback over time and became gradually more capable of providing corrective feedback. The qualitative analysis of student interviews provided evidence that students valued peer feedback in their portfolios. The analysis of the teacher interview showed that average and high-ability students benefited the most from peer feedback. This study provided evidence that e-portfolios can support the development of students' writing performance and peer feedback skills in the context of primary school essay writing. Instructional implications for portfolio implementation are offered. 相似文献

With the advent of computer technology, researchers and instructors are attempting to devise computer support for effective
collaborative technical writing. In this study, a computer-supported environment for collaborative technical writing was developed.
This system (Process-Writing Wizard) provides process-oriented scaffolds and a synchronous online chat room to facilitate real-time collaborative writing practice.
It allows multiple students to work synchronously on collaborative writing tasks via the Internet. It also helps develop collaborative
writing strategies, such as creating team agendas, brainstorming, creating team outlines, and generating team articles. An
experiment was conducted to examine the effect of the system on EFL (English as a Foreign Language) students’ collaborative
writing experiences. First, an attitude questionnaire was used to evaluate learners’ perceptions, acceptance, attitudes, and
continuing motivation toward the functionalities and guidance provided by the system. Second, students’ writing products were
examined to evaluate the effect of the system on EFL students’ collaborative writing quality, especially on content and organization.
Finally, this study analyzed and coded students’ synchronous chats with three categories (article-related interactions, social
interactions, and system operation-related interactions) to evaluate the effect of the system on students’ interactions. The
results of the experiment showed: (1) the students had positive attitudes toward the system and continuing motivation to use
the system in future writing tasks; (2) analysis of writing products suggested that students produced better content and organization
with the support of the system; (3) the procedural facilitation provided by the system successfully scaffolded students to
converse more in the category of article-related interactions. Limitations and future research directions are also discussed. 相似文献

In this paper we present a modern approach of teaching mathematics based on the computer supported collaborative learning (CSCL) of calculus contents. The collaborative learning was used in calculus course at the University of Novi Sad, Serbia, for examining functions and drawing their graphs. In 2012 the authors decided to improve the collaborative learning introducing GeoGebra application. Small four member groups were formed by using Kagan's (1994) principles. Two groups of students, the experimental, and the control one were observed. The students in the experimental group learned with the help of GeoGebra, and the students in the control group learned without using GeoGebra.Comparison between those two groups of the first year calculus students, regarding their way of learning and the results achieved, is described below. Before the students' collaborative learning, they were tested with a pre-test and their knowledge necessary for examining functions was verified. The pre-test showed that there was no significant statistical difference between the experimental and the control group. The experimental group worked with the help of the computer and the control one without it. After the collaborative learning, the students were tested with a test (colloquium) and the results of the experimental group were significantly better than the results of students in the control group. At the end of the course the students did their exams (post-test), and the results of the experimental group were significantly better than the results of students in the control group.Some students from the experimental group had to answer questions in an interview related to the use of GeoGebra during their collaborative learning. In order to see the students' difficulties in solving problems, students in the experimental group were asked to cross out incorrect parts of solutions, not to erase them. The teachers reviewed the students' tasks done during the collaborative learning and after that the students who had corrected their mistakes were invited for an interview about using GeoGebra for overcoming their difficulties. Based on the students' results in the tests, answers in the questionnaire and in the interview, it can be concluded that GeoGebra has enabled an easier learning of this material. The GeoGebra package enables the students to check whether each step in the process of solving a task was correctly done or not. The results of our research show that GeoGebra can help those students having insufficient knowledge (necessary for solving those tasks) to improve it.We can say that our research shows that the students' learning achievement in examining functions and drawing their graphs is better when they use GeoGebra, working in collaborative groups than without using it. Also, GeoGebra enables creation of effective learning environment for examining functions and drawing their graphs. 相似文献

This study addresses to what extent and how electronic outlining enhances students' writing performance. To this end, the focus of this study is not only on students' final writing products but also on the organisation of the writing process (i.e., planning, translating, and reviewing) and perceived mental effort during writing. In addition, effects of repeated electronic outlining were examined. A combined within and between subjects design was implemented in which 93 10th-grade students wrote two argumentative texts with or without using electronic outlining. Analyses showed that using electronic outlining for planning and writing significantly improved the presentation of the argumentative structure. However, effects were less clear for correctly and completely establishing a text structure and no effects were found on the elaboration of students' argumentation. Process data showed that electronic outlining increased total process time, but no effect was found on students' overall planning and revision activities. Finally, self-reports showed no effect of electronic outlining on students' perceived mental effort. Nevertheless, repeated use of the same writing strategy enhanced writing fluency. 相似文献

This paper focuses on the design and evaluation of a theory‐based computer‐assisted summary writing learning environment called Summary Writing‐PAL (SW‐PAL). The SW‐PAL was developed based on four aspects: summarizing strategies, learning theories, prior knowledge, and cognitive load. A quasi‐experiment that involved 58 undergraduates majoring in Computer Science was conducted to examine the effectiveness of SW‐PAL in writing summaries. Two intact classes were selected with 28 and 30 students in control and experimental groups, respectively. The conventional teaching approach was employed in the control group, whereas the SW‐PAL was introduced to the experimental group. Pretest and posttest were administrated to both groups. The findings indicated that SW‐PAL improved students' summary writing performance. A significant variance was noted between intrinsic and extraneous cognitive load among students with varying levels of English proficiency in the experimental group, signifying that the SW‐PAL is more suitable for students with lower language proficiency. 相似文献

Over the last decade, Alternate Reality Games (ARGs), a form of narrative often involving multiple media and gaming elements to tell a story that might be affected by participants’ actions, have been used in the marketing and promotion of a number of entertainment related products such as films, computer games and music. This paper discusses the design, development and evaluation of an ARG aimed at increasing the motivations of secondary school level students across Europe in the learning of modern foreign languages. The ARG was developed and implemented as part of a European Commission Comenius project and involved 6 project partners, 328 secondary school students and 95 language teachers from 17 European countries. The collaborative nature of ARGs provides a potentially useful vehicle for developing collaborative activities within an educational context. This paper describes the educational value of ARGs, in particular the ARG for supporting the teaching of modern European languages and the specific activities that were developed around Web 2.0 and gaming that underpinned the ARG and helped promote cooperation and learning within an educational environment. An evaluation of the ARG was conducted using an experimental design of pre-test → ARG intervention → post-test. 105 students completed the pre-test, 92 students completed the post-test and 45 students completed both the pre-test and post-test questionnaires. In general, student attitudes towards the ARG were very positive with evidence suggesting that the ARG managed to deliver the motivational experience expected by the students. The majority of students who completed the post-test either agreed or strongly agreed that they would be willing to play the game over a prolonged period of time as part of a foreign language course. In addition, through using the ARG, students believed that they obtained skills relating to cooperation, collaboration and teamwork. 相似文献

Summary writing is a useful instructional tool for learning. However, summary writing is a challenge to many students. This mixed-method study examined the potential of the Student Mental Model Analyzer for Research and Teaching (SMART) system to help students produce summaries that reflect key concepts and relations in a text. SMART uses the students' summary to generate a multi-dimensional 3S (surface, structure, semantic) evaluation of the students' mental model. This model is then used to drive feedback to help students revise their summary. The current study is an initial investigation examining whether writing and revising in SMART improves students' summary quality. Students (n = 38) in a graduate-level online course used SMART for seven reading assignments. The 38 students submitted a total of 357 summaries in response to the seven readings. In 47 cases, students produced both an initial draft and a modified revision. These 47 cases were selected for analysis. In the quantitative phase, MANOVA results indicated that students' summaries improved along the 3S dimensions from initial draft to revision. In the qualitative phase, inspection of exemplar cases revealed how students' mental models changed towards more robust and cohesive knowledge structure for texts. 相似文献

Writing correct English sentences can be challenging. Furthermore, writing correct formulaic sequences can be especially difficult because accepted combinations do not follow clear rules governing which words appear together in a sequence. One solution is to provide examples of correct usage accompanied by statistical feedback from web‐based applications for learners to emulate. The goal of the study was to investigate whether such a dedicated web‐based program that provides instant examples of correct word combinations and detailed results of who used these examples, where and when, can improve students' writing. Data were collected from 74 ESL (English as a Second Language) undergraduate students divided into control and experimental groups, who performed formulaic sequence tests, wrote passages in English, followed by interviews with members of the experimental group. The results show that students who used the software outperformed those who did not, on the tests and the overall grades for their writing. Implementing formulaic sequence check programs in writing classes to help students decide which words can appear together, under which circumstances, and in which context is recommended. 相似文献

The aim of the study is to investigate the possible effect of web-supported teaching on students' academic achievement in Human Rights, Democracy and Citizenship Education. To examine weather web-supported instruction would make a difference in attainment level of the subjects, a mixed method research design i.e. focus group interview and Solomon-four-group experimental design was employed. Solomon design contains two extra control groups to the experimental design, which serve to reduce the influence of confounding variables and allow researchers to test whether the pre-test itself has an effect on the subjects. An achievement test designed for this study was employed to collect data on dependent measures. After subjecting experimental group students to a 12-week-long web-supported learning, the same test (as post-test) was applied to all control and experiment groups in both universities, 8 in total. The data was analyzed by using t test and one-way ANOVA. There was no statistically significant difference between experimental and control groups in achievement post-test scores. 相似文献

This paper presents findings of a study of high school students participating in a tablet PC (TPC) programme. Primary areas of interest were students' experiences with and attitudes about the TPCs, physical discomfort associated with use of TPCs and temporal and task-driven patterns of TPC use. Data were collected via questionnaire and computer use-monitoring software. Results showed students' attitudes were generally quite positive towards the TPCs, although they did not tend to think TPCs had improved their grades, few disagreed that TPCs were a distraction in class, and visual and musculoskeletal discomfort was prevalent. Understanding how to use the TPC and recognizing its organizational capacity were associated with several positive attitudes towards the TPC, including making school more enjoyable. Children's exposure to computers will only increase, so study of the many dimensions of their impact is critical in order to understand what is effective, constructive and healthful for children. 相似文献

Abstract This study investigated the effects of a Problem-Solving based Computer-Assisted Tutorial (PSCAT) on earth science achievement and attitudes toward earth science of tenth graders (16-year olds) in a senior high school in Taiwan. A total of 137 students who were enrolled in four earth science classes participated in this pre-test/post-test control-group experiment. The experimental groups received the PSCAT; whereas the comparison groups received a Lecture-Internet-Discussion (LID) teaching approach. A multivariate analysis of covariance on the post-test scores of the Earth Science Achievement Test and Attitudes Toward Earth Science Inventory, with students' pre-test scores as the covariates, suggested that PSCAT produced (almost) significantly greater gains on students' earth science achievement than did the LID approach and that no statistically significant increase or decrease in student attitudes toward earth science was found for either group. 相似文献

This study examined the effect of electronic outlining on the quality of students' writing products and how outlining affects perceived mental effort during the writing task. Additionally, it was studied how students appropriate and appreciate an outline tool and whether they need explicit instruction in order to engage in planning. To answer these questions, the writing products and self‐report data from 34 tenth‐grade students of a Dutch pre‐university school were analysed. Students wrote two similar argumentative texts with or without an outline tool. Results show that electronic outlining improves the quality of students' argumentative texts and decreases mental effort. Answers to a retrospective questionnaire showed that a short instruction on the outline tool was sufficient for students to understand its working and that most students experienced the tool as beneficial. Finally, results indicate that without specific instruction on text planning, students hardly devote any time to this important aspect of writing. 相似文献

The purpose of this study was to investigate the effects of two different methods on primary school teacher candidates’ academic achievements and attitudes toward computer-based education, and to define their views on these methods. Both the first experimental group, programmed instruction (PI), and the second experimental group, meaningful learning (ML), included 36 students separately. While a significant difference was found between the groups regarding academic achievements, no significant difference was found between the groups’ attitude scores. There was no significant difference between the academic achievements of the students according to their genders in both groups. In addition, while there was no significant difference between the pre-test and post-test attitudes of students in the PI group, a significant difference was determined in the ML group. Generally, in the PI group, students considered the method effective but boring. Besides, students in the ML group had positive views on the method. 相似文献

Although educators over the past decade have developed various scales measuring students' computer attitudes, few of them have constructed scales specifically for attitudes towards the Internet. The purpose of this study was to develop an Internet attitude scale for high school students. Through both revising a previous scale proposed by Selwyn (1997) [Selwyn, N. (1997). Students' attitudes toward computers: validation of a computer attitude scale for 16–19 education. Computers & Education, 28(1), 35–41] and writing new items, this study developed an Internet Attitude Scale of 18 items, with the following four subscales: perceived usefulness, affection, perceived control, and behavior. This study also explored gender differences on the scale, and the relationship between Internet experience and students' responses on the scale. Research data gathered from 753 Taiwan high school students revealed that students of different gender and various Internet experiences did not show statistical differences on the perceptions toward the potential usefulness of the Internet subscale. However, male students tended to express more positive feeling, lower anxiety, and higher confidence toward using the Internet than female students. Students having more Internet experience tended to show similar positive attitudes than those of less experience. 相似文献

The aim of this study was to investigate the effect of using dynamic geometry software (GeoGebra) on the eighth-grade students' conceptual understanding and the retention of learning regarding linear equations and slope. In this study, a quasi-experimental design with pre-test, post-test and delayed post-test was employed. This study was conducted with 52 eighth-grade Turkish students (experimental group, n = 25; control group, n = 27). While GeoGebra software-supported instruction was carried out in the experimental group, textbook-based direct instruction was continued in the control group. Data were collected with the conceptual understanding test (CUT) which consists of 38 questions including open-ended, multiple choice and fill in the blanks. CUT was applied to the experimental and control groups as a pre-test and post-test at both the beginning and the end of the instruction, respectively. Seven weeks after the instruction, CUT was applied to both groups as a retention test. Data were analysed through SPSS 17.0 statistical software by using a t-test and ANCOVA test. It was indicated in the study results that GeoGebra software-supported instruction for eighth-grade students regarding linear equations and slope did significantly improve both their conceptual understanding and retention of learning in comparison to textbook-based direct instruction. 相似文献

This research study aims to identify student's perceptions regarding the use of blogging, the pattern of reflection involved in learning Authoring System through blogging and student's performance in tests based on the reflection's pattern. Sixteen students who registered for the Authoring System subject participated in this study. It was conducted using quantitative approaches, through survey and pre-experimental design of one group post-test type. The instruments used were questionnaire, performance test and blog contents, where tutors and students posted messages and comments on the blog during the course. The results showed that the students' overall perception regarding the educational benefits of writing a blog and reading other students' blogs and comments was positive. Students also moderately agreed that they had difficulties in engaging in the reflection through blogging. It was also found that blogging indirectly improved the students' performance in the test. Through blog content analysis, the dominant type of reflection was monologue. However, the results from the data mining analysis showed that the students used reflective conversation and monologue type of reflection to achieve Grade A in learning Authoring System. It shows that students require deep and critical reflection to perform better in the subject. 相似文献

Improving students' reading comprehension is of significance. In this study, collaborative learning supported by Group Scribbles (GS), a networked technology, was integrated into a primary reading class. Forty‐seven 10‐year‐old students from two 4th grade classes participated in the study. Experimental and control groups were established to investigate the effectiveness of GS‐supported collaborative learning in enhancing students' reading comprehension. The results affirmed the effectiveness of the intervention designed. In the experiment group, students' learning attitudes, motivation and interest were enhanced as well. Further analyses were done to probe students' interaction processes in the networked collaborative classroom and different collaboration patterns and behaviours were identified. Based on the findings obtained, implications for future learning design to empower L1 learning were elaborated. 相似文献

This study investigated the effects of an individually personalized computer-based instructional program on the achievement and attitudes regarding mathematics computational problems and word problems of 104 middle school American students. Students were blocked by math entering knowledge based on pre-test scores, then randomly assigned to a personalized or non-personalized version of the computer-based instructional program. A significant two-way interaction (treatment by math entering knowledge) reflected that personalized higher-level math entering knowledge students and non-personalized higher-level math entering knowledge students had similar post-test scores but personalized lower-level math entering knowledge students scored significantly higher on the post-test than non-personalized lower-level math entering knowledge students. Another significant two-way interaction (math entering knowledge by problem type) reflected that students with higher-level math entering knowledge scored considerably higher on the computational problems than on the word problems while students with lower-level math entering knowledge scored significantly higher on the computational problems than on the word problems. Student attitudes were significantly more favorable toward the personalized computer-based instructional program. 相似文献
