Understanding complex conceptual relationships is crucial for Korean high school history learning. The motivating hypothesis for this study is that a Cognitive Flexibility Theory‐based Hypertext instructional module will promote acquisition of advanced knowledge associated with complex conceptual relationships. This study focussed on improving Korean history teaching and learning in terms of these learner characteristics based on Cognitive Flexibility Theory, an influential constructivist approach in the field of educational technology. A referential hypertext program based on Spiro and his colleagues’ (1988, 1990) Cognitive Flexibility Theory (CFT) was developed for this study. Three learning programs were presented: (1) Cognitive Flexibility Theory‐Based Hypertext (CFTH), (2) hierarchical hypertext, similar to CFTH except for its hierarchical node connections, and (3) a textbook representing the typical Korean high school history instruction process. The effects of these three treatments on history achievement were examined in terms of post‐test item characteristics. Independent variables were students’ IQ, and prior knowledge and motivation toward each learning program that was measured after the treatment. Students’ achievement was the highest among three groups, especially in complex items: comparison, analysis and synthesis. In the CFTH group high IQ and low PK students’ achievement was most improved, and motivation was the chief influential factor in explaining the achievement.  相似文献

The purpose of this study was to develop and validate an online contextualized test for assessing students’ understanding of epistemic knowledge of science. In addition, how students’ understanding of epistemic knowledge of science interacts with learner factors, including time spent on science learning, interest, self-efficacy, and gender, was also explored. The participants were 489 senior high school students (244 males and 245 females) from eight different schools in Taiwan. Based on the result of an extensive literature review, we first identified six factors of epistemic knowledge of science, such as status of scientific knowledge, the nature of scientific enterprise, measurement in science, and so on. An online test was then created for assessing students’ understanding of the epistemic knowledge of science. Also, a learner-factor survey was developed by adopting previous PISA survey items to measure the abovementioned learner factors. The results of this study show that; (1) by factor analysis, the six factors of epistemic knowledge of science could be grouped into two dimensions which reflect the nature of scientific knowledge and knowing in science, respectively; (2) there was a gender difference in the participants’ understanding of the epistemic knowledge of science; and (3) students’ interest in science learning and the time spent on science learning were positively correlated to their understanding of the epistemic knowledge of science.  相似文献

A study is presented that explores how students’ knowledge structures, as related to the scientific method, compare at different student ages. A word association test comprised of ten total stimulus words, among them experiment, science fair, and hypothesis, is used to probe the students’ knowledge structures. Students from grades four, five, and eight, as well as first-year college students were tested to reveal their knowledge structures relating to the scientific method. Younger students were found to have a naïve view of the science process with little understanding of how science relates to the real world. However, students’ conceptions about the scientific process appear to be malleable, with science fairs a potentially strong influencer. The strength of associations between words is observed to change from grade to grade, with younger students placing science fair near the center of their knowledge structure regarding the scientific method, whereas older students conceptualize the scientific method around experiment.  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

Involving students in the co-design of educational curricula and practices can benefit both students and teachers. Students who participate in co-design may show better learning or increased agency or engagement. In the present study, we investigated what kind of science knowledge or practices can be learned by student co-designers while engaging in co-design practices and how that learning happens with six high school students. We created a model to guide the analysis of students’ learning with technology in co-designing processes. The results revealed that students learned engineering design process even if no explicit instruction on engineering learning was given. Also, our analysis suggested that co-designing with technology enabled learning of the engineering design process and potentially furthered learning of science because it promoted knowledge integration. The results have implications for understanding and enhancing engineering design and science learning through co-designing with technology.

This article puts forward a project approach and a set of solutions to better prepare foreign students wishing to enter engineering schools in France. It focuses on how we train students to understand scientific presentations through intensive listening comprehension. Within this framework, it proposes a new educational ICT model that is original from both a pedagogical and a technical point of view. This model was achieved as a result of close collaboration between experts in the fields of science, linguistics, intercultural relations and educational ICT.  相似文献

This article argues that whatever the 2015 OECD report says about the value of ICT in relation to PISA results, our research has shown that using ICT in the education of students with Learning Difficulties has great value in interesting, enthusing and inspiring these students, so leading to better educational outcomes. The term ‘Learning Difficulties’ (LD) is used to refer to a condition of a large group of children who need extra assistance with schooling and arises from a vast range of cognitive and physical impairments. The reported research was conducted in two Special Schools in metropolitan Melbourne with the goal of investigating whether, and if so how, ICT could be used to support school communities involving students with learning difficulties, and whether it could help these students with their learning. This research found that ICT certainly does improve LD students’ attitude to learning and equips them with adequate skills to allow them to enter the workforce or continue with further study through various pathways. It provides evidence that for LD students, a significant attainment in skills and academic knowledge is facilitated by the adoption of ICT in the classroom.  相似文献

Technology has become an essential component in our society and considering its impact in the educational system, Information and Communication Technologies (ICT) cannot be dissociated from the educational process and, in particular, from pedagogical practices adopted for students who are blind or partially sighted. This study focuses on Portuguese reference schools for the education of blind and partially sighted students, regulated by the Decree-Law No. 3/2008, in which are concentrated the human and material resources that can offer an educational response with quality for these students with special education needs. The study intends to analyse the perceptions of the teachers, who teach visually impaired students in middle school and secondary school education in these reference schools, of their knowledge, teaching and training in the area of ICT, as well as of the real ICT integration in the teaching and learning of these students. A survey, which has been applied to these teachers in the 2012/13 school year, was adopted as a method of data collection. The results reveal a sample confident in their technological capabilities, however with little resourcefulness in some tools and software specific to the area of visual impairment and a very significant number of teachers ignoring many of these. The implementation of ICT with students who have visual disabilities is lower compared with the sighted students. The lack of specific training is considered to be the main obstacle for teachers, with regard to the real integration of ICT in the teaching and learning of these students.  相似文献

Multimedia effects in learning receive much attention in research. In contrast, effects of different picture types in testing materials are hardly studied. The present computer-based experiment with n = 404 students investigates the effects of adding a representational picture (RP) or a decorative picture (DP) to text-based educational test items on students' performance, metacognition, test-taking motivation and item processing in the domains of science and mathematics. The data show that RPs enhanced students' performance, perception of ease and test-taking pleasure in both scientific and mathematics items. Furthermore, RPs increased time on task (TOT) in mathematics, but not in scientific items. DPs had no significant effect on students’ performance, test-taking pleasure or perceived ease, while DPs reduced TOT in mathematics items. Explanations for the process-related differences are discussed. The pattern of results indicates that the multimedia principle and the coherence principle from instructional psychology can be transferred to educational testing material.  相似文献

There is an expectation that new science teachers will be able to effectively use a range of information communication technology (ICT) related resources inthe science classroom in order to enhance student learning. All school systems in Australia are in the process of providing teachers with ICT professional development and infrastructure. This paper outlines a range of initiatives designed to integrate ICT in a compulsory science education unit for students enrolled in a Graduate Diploma in Secondary Education. An action research model based on constructivist principles was used to evaluate the effectiveness of modelling, open-ended co-operative group activities and authentic assessment in enabling students to enhance their ICT skills, knowledge and pedagogical content knowledge in a science education context. Multiple sources of data were generated including a pre and post unit questionnaire that was analysed using Rasch modelling. The questionnaire determined students' perceptions of their preparedness to teach using ICT. The findings of this research suggest that some skills warranted greater attention in the unit, but students' pedagogical knowledge and knowledge and critique of ICT resources were enhanced over the duration of the unit.  相似文献

Climate change science is a challenging topic for student learning. This quantitative study examined the effectiveness of a geospatial curriculum approach to promote climate change science understandings in an urban school district with eighth-grade students and investigated whether teacher- and student-level factors accounted for students’ climate change knowledge achievement. The participants included 12 science teachers and 956 eighth-grade students. Data included a pre- and posttest climate change assessment measures for both teachers and students and a teacher measure of Geospatial Science-Technological Pedagogical Content Knowledge. Paired-sample t tests revealed statistically significant gains from pretest to posttest on their climate change knowledge (p < .001; effect sizes being large on multiple-choice items and medium on the open-ended response assessment). Both ordinary least squares (OLS) multiple regression and 2-level hierarchical linear modeling found that students’ initial climate change knowledge and gender were significant predictors for students’ posttest scores, p < .05. Students’ pretest scores were the strongest significant predictor of the posttest scores, p < .001. Neither the teachers’ climate change knowledge nor their Geospatial Science-Technological Pedagogical Content Knowledge had significant association with the students’ posttest scores. Teaching years was a significant predictor for students’ posttest scores in OLS regression (p < .001). The findings provide support that a geospatial curriculum approach is an effective science curriculum approach for learners in urban middle-level education.  相似文献

Since our first studies of information and communications technology (ICT) skills and ICT use at universities in 2004, ICT and its use by students has changed greatly. In order to obtain a more detailed picture of ICT skills, we first construct a new instrument to measure the self-perception of ICT skills (49 items) and of ICT use (53 items) by students. This allows us to find some patterns for ICT skills and ICT use. In order to explain these patterns, two basic hypotheses are formulated. The first suggests that positive ICT learning experiences at home, in school, and with peers could contribute to mastering a higher level of ICT skills and more frequent use of ICT among bachelor’s students, a hypothesis that aligns with Dewey’s learning theory. The second hypothesis suggests that there is a similarity between the characteristics of information systems and scientific research, and that students who identify more with scientific research would be more likely to have greater ICT skills and a higher frequency of ICT use. Both hypotheses are tested among bachelor’s students, using some important contextual variables (gender, domain of study, ICT course in secondary school or at university, and education level of parents). It can be concluded that there is a relationship between the ICT learning experience and the research-oriented identity commitment of bachelor’s students on the one hand, and their command of ICT skills and the frequency of use of computers, ICT instruments, and ICT programs on the other.  相似文献

This study investigated eighth-grade science students’ (13–14-year-olds) perceptions of their vocabulary knowledge, learning, and content achievement. Data sources included pre- and posttest of students’ perceptions of vocabulary knowledge, students’ perceptions of vocabulary and reading strategies surveys, and a content achievement test. Students’ perceptions of vocabulary knowledge were compared before and after instruction to see whether students believed they gained knowledge and the ability to explain categories of technical science terms. Students’ perceptions of vocabulary knowledge increased as a result of instruction. The participants had favorable views of the vocabulary and reading strategies implemented and believed the literacy approaches were important for their developing science knowledge. In addition, students’ content achievement was compared to a national data set. Students in this study outperformed a national data set on all content knowledge items assessed. Students’ perceptions of their knowledge and vocabulary and reading strategies were congruent with their content achievement. This study is one of the first to highlight the pivotal role students’ perception of vocabulary knowledge and vocabulary and reading strategies plays in science content learning.  相似文献

Since at least the eighteenth century scientific knowledge (then natural philosophy) was produced in groups of experts and specialists and was transmitted in schools, where, future experts and specialists were trained. The design of teaching has always been a complex process particularly in recent years when educational aims (for example, teaching scientific competence to everyone, not just to experts and specialists) present significant challenges. These challenges are much more than a simple reorganisation of the scientific knowledge pre-determined by the existing teaching tradition for different educational level. In the context of chemical education, the new teaching approaches should bring about not only the transmission of chemical knowledge but also a genuine chemical activity so as to ensure that students can acquire chemical thinking. Chemistry teaching should be revised according to contemporary demands of schooling. In order to move forward towards new teaching proposals, we must identify the genuine questions that generate ‘chemical criteria’ and we should focus on them for teaching. We think that a good strategy is to look for those criteria in the philosophy and history of chemistry, from the perspective of didactics of science. This paper will examine the following questions: (1) How can school science be designed as a world-modelling activity by drawing on the philosophy of science. (2) How can ‘stories’ about the emergence of chemical entities be identified by looking at the history of chemistry? (3) How can modelling strategies be structured in school chemistry activities?  相似文献

The process to integrate information and communication technologies (ICT), where teachers play a decisive role, is complex. The objective of this study is to build a basic model that connects teachers’ ICT technological and pedagogical competences with the use of these technological resources by teachers (both personal-professional use and use with students). The model also considers how personal and contextual factors influence this relationship. A secondary analysis study was used, whose sample included 1095 male and female Primary, Secondary and Higher Education teachers from the Valencian Community (east Spain). Information was collected with a questionnaire from two survey design studies. Using an MIMIC model, teachers’ integration of ICT was optimally modeled. This model shows a complex relation between competence and use. Technological competences influence pedagogical competences and personal-professional use, while pedagogical competences influence personal-professional use and use in class. Use in class is influenced by both pedagogical competences and personal-professional use. Personal and contextual factors influenced the four dimensions of use and competence. This basic model of the relationship between teachers’ ICT competences and using these educational resources helps us to understand the complex process of integrating ICT into classrooms. Therefore, this model is a key element to guide teacher training in ICT.  相似文献

The Seventh School Curriculum Reform in Korea was introduced in 2000 to prepare school‐aged Koreans for an information and knowledge‐based society. The reform effort emphasises information and communication technology (ICT) in the K–12 curriculum and a learner‐centred pedagogy. This study examines the contributions of ICT, specifically, computer‐assisted instruction (CAI), in Korean science classrooms. A sample of 234 Korean middle school students was categorised into five achievement groups. Data were collected from pre‐ and post‐achievement test scores and pre‐ and post‐questionnaires for attitudes toward science, future courses, and career aspirations in science. Findings include: (1) the lowest achievement group showed the most significant improvement after CAI (p=.000); (2) an improvement in student achievement in science significantly influenced students’ attitudes toward science (p=.019), future course selections, and career aspirations related to science (p=.000); and (3) boys tended to perform better with CAI than girls. This research provides evidence that CAI has the potential to help lower achieving students in Korean science classes and may encourage enrolment in science.  相似文献
