Our study capitalized on a unique natural experiment rather than a researcher-designed, randomized experiment whereby, thanks to the Australian Government's Digital Education Revolution, half of grade 9 students in 2008 received laptops and half did not. Consequently in late 2011, when these students sat for their grade 12 external examinations based on the same curriculum implemented across the state of New South Wales, half of them had been schooled with 1:1 laptops for over three years, and half without. With school principals and district administrators asking the question ‘what will these laptops do to our examination results?' this dichotomous scenario presented us with a unique opportunity to find out. The aim of this study was to evaluate if having 1:1 laptops was a predictor of success in the sciences in the external examinations. The science students (N?=?967) from 12 high schools in Sydney, Australia were studied. Using socio-demographic, school and examination data, multiple regression analyses were performed to measure the impact of the 1:1 laptop provision and other variables on student attainment in biology, chemistry and physics. We found that being schooled with 1:1 laptops had statistically significant and positive standardized regression coefficients with student attainment, with a medium effect size in physics (0.38), and small effect sizes in biology (0.26) and chemistry (0.23). Upon further investigation, exploring data provided by student and teacher questionnaires, we found that the greater effect size in physics corresponded with greater use of simulations and spreadsheets by students and teachers.  相似文献

The study examines the professional development of junior-high-school teachers participating in the Israeli “Katom” (Computer for Every Class, Student and Teacher) Program, begun in 2004. A three-circle support and training model was developed for teachers’ professional development. The first circle applies to all teachers in the program; the second, to all teachers at individual schools; the third to teachers of specific disciplines. The study reveals and describes the attitudes of science teachers to the integration of laptop computers and to the accompanying professional development model. Semi-structured interviews were conducted with eight science teachers from the four schools participating in the program. The interviews were analyzed according to the internal relational framework taken from the information that arose from the interviews. Two factors influenced science teachers’ professional development: (1) Introduction of laptops to the teachers and students. (2) The support and training system. Interview analysis shows that the disciplinary training is most relevant to teachers and they are very interested in belonging to the professional science teachers’ community. They also prefer face-to-face meetings in their school. Among the difficulties they noted were the new learning environment, including control of student computers, computer integration in laboratory work and technical problems. Laptop computers contributed significantly to teachers’ professional and personal development and to a shift from teacher-centered to student-centered teaching. One-to-One laptops also changed the schools’ digital culture. The findings are important for designing concepts and models for professional development when introducing technological innovation into the educational system.  相似文献

There is, no doubt, untapped potential in using technological tools to enhance the understanding of science concepts. This study examines the potential by observing 7th and 8th grade middle school students’ (n = 23) use of portable data collection devices in a nine-week elective class, Exploring Technologies. Students’ use of the data collection devices and subsequent interactions were traced through audiocassette and videocassette recordings, field notes, and student artifacts. The culminating activity for the course was a scientific investigation that required students to use the technologies to answer student-selected research questions. To illustrate the use of technology as a mediatory tool, an inquiry investigation of three student groups is described. In examining the three groups of middle school students the researchers encountered specific evidence of technology maximizing students’ science learning. The students were able to use the portable data collection devices in their investigations as they discussed scientific ideas related to temperature and heat. The study’s findings indicated that the three student groups were able to use the tools to conduct scientific inquiry and engage in scientific discourse. Further research on instructional approaches that allow students to develop expertise by using technology as tools to construct knowledge about complex phenomena is encouraged.  相似文献

The effects of two types of two well-established microcomputer-based teaching methods were examined for their effect teaching high school students kinetics. The use of data acquisition probeware and digital video analysis were studied for their impact on students’conceptions and ability to interpret graphical relationships to real world events. The abilities of high school physics students to accurately graph kinetics using distance, velocity and acceleration in one dimensional motion varied between and among the groups. Using a split category random assignment analysis students investigated these motions with both. In a quasi experimental fashion students received similar instruction on each but in a different sequence. Students received the similar teaching in reverse order and both strategies were found to be successful and complementary. There were indications student achievement was higher for velocity–time and acceleration-time graphs using the digital video analysis method. Implications for this study on teaching tools, methodologies, curriculum development, program implementation, and assessment are discussed.  相似文献

This research effort reports the findings of an empirical study focusing on the ways in which technological tools are implemented specifically in mathematics education in a Title I school. The purpose was to identify the perspectives and actions of the school’s mathematics specialist and the multi-graded (grades 2–3) classroom teacher as they attempted to deliver instruction with technology for both English Language Learners1 (ELL) and non-ELL students. Findings showed that a critical factor in access to mathematics education and technology for ELL students in a multi-graded 2–3 classroom in a Title I (K-5) school setting was language. Although potentially powerful technologies—analog (concrete objects) and digital (software) were used, many ELL students could not access the content solely because of language difficulties. Teachers used the concrete objects as modeling tools, to reveal students’ thinking, and for communication of foundational mathematics. Conversely, the software used served none of these functions because the available software did not do the kinds of things the manipulatives did, teachers’ knowledge of exemplary software was insufficient, the school used an impoverished model of technology integration, and teachers were constrained by the school district’s policies of English immersion for ELL students.This paper was presented at the American Educational Research Association Annual Meeting, 2005, Montreal, Canada, on Tuesday, April 12, 2005, 4:05–5:35 pm, in Le Centre Sheraton Montreal/Salon 7, in a session titled, “Science and Mathematics Teaching for Linguistically and Culturally Diverse Students” sponsored by Division K-Teaching and Teacher Education/Section 1—Research on Teaching Practices, Teacher Knowledge, and Teacher Education in Math and Science.Tirupalavanam G.

This position paper proposes the enhancement of teacher and student learning in science classrooms by tapping the enormous potential of information communication and technologies (ICTs) as cognitive tools for engaging students in scientific inquiry. This paper serves to challenge teacher-held assumptions about students learning science ‘from technology’ with a framework and examples of students learning science ‘with technology’. Whereas a high percentage of students are finding their way in using ICTs outside of school, for the most part they currently are not doing so inside of school in ways that they find meaningful and relevant to their lives. Instead, the pedagogical approaches that are most often experienced are out-of-step with how students use ICTs outside of schools and are not supportive of learning framed by constructivism. Here we describe a theoretical and pedagogical foundation for better connecting the two worlds of students’ lives: life in school and life outside of school. This position paper is in response to the changing landscape of students’ lives. The position is transformative in nature because it proposes the use of cyber-enabled resources for cultivating and leveraging students new literacy skills by learning ‘with technology’ to enhance science learning.  相似文献

The uptake and use of digital technologies is studied in Unos Umeå, a joint one-to-one (1:1) research project between Umeå University and the municipality of Umeå in Sweden. This article presents the results of the third phase of the classroom work with laptops. Using the ecology of resources model (Luckin, 2010), these possibilities and challenges can be interpreted as the manifestation of filters in the learning environment. Alleviating technical problems, targeting low student laptop use, teacher collaboration, and teacher professional development (TPD) may help teachers and students gain and sustain technology-enhanced learning (TEL) in this 1:1 initiative.  相似文献

Students’ satisfaction with school experiences has been linked to their sense of belongingness, connection to school, and achievement. Though the extant research addresses students’ perceptions of school climate and sense of belonging, there is a paucity of research about students’ views of teacher–student interactions. Five hundred and seventy-seven students from one ethnically and academically diverse urban high school were surveyed and interviewed about the nature of teacher talk with students. Findings from this mixed-methods investigation indicate students from general, special, and honors programs experience a wide range of interactions based on academic services received, gender, and ethnicity. More frequent perceived punitive feedback was reported by all students in special education as well as males in general and honors education programs, while Hispanic students indicated a greater frequency of perceived supportive feedback. Findings also reflect a wide range of attitudes and feelings about teachers, the educational system, and learning.  相似文献

To what extent can a large-scale national teacher-enhancement project help science teachers employ new pedagogical methods in the science classroom? In this study, data from 13 high school physics teachers who taught 23 classes with 401 students were examined to determine the extent to which a teacher-enhancement project can alter teachers’ pedagogy. Three groups of teachers were examined: experienced users of the new pedagogy, beginning users of the new pedagogy, and a group of comparison teachers who used traditional instructional methods. Results suggest the reform effort can increase the extent to which teachers engage students in experiments and use alternative assessment methods; however, helping teachers use constructivist discussion methods and discuss the nature of scientific inquiry appears to be more difficult. The implications for inservice teacher education are discussed.  相似文献

In this article, the authors explored how laptops used in 1:1 classrooms affect cooperation and collaboration practices. Based on an observational time study, the authors found that the most common activity in 1:1 classrooms is group work using the computer. They also found that, despite what the concept 1:1 alludes to about one student working with one computer, most laptop use takes on other forms such as two students working with one computer (1:2) or two students working together using two laptops (2:2). The findings reported in this article about the various different collaboration arrangements have implications for both research and practice. For practice, because teachers can arrange activities based on an awareness of the different student–laptop constellations that emerge when students are given a laptop. Research is likewise informed about the various group work constellations and can build on this knowledge for further analysis of the pros and cons with the different collaborative forms.  相似文献

In the United States today, urban schools serve the majority of high-poverty and high minority populations including large numbers of Hispanic students. While many Hispanic students perform below grade level in middle school science, the science teaching community as a whole is lacking elements of diversity as teachers struggle to meet the needs of all learners. Researchers have recognized that science teacher effectiveness, one consequence of self-efficacy among teachers, is associated with future science achievement and science-related careers of their students. This qualitative study explores how three science teachers’ effectiveness in the classroom impacts students’ science self-efficacy beliefs at one urban middle school. Hispanic students were the focus of this investigation due to demographics and history of underperformance within this district. Teachers’ perspectives, as well as outside observer evaluations of instructional strategies and classroom climates were triangulated to explore dynamics that influence students’ interests and motivation to learn science using a framework to link teachers’ sense of efficacy (focusing on student outcomes). Findings suggest the impact teacher effectiveness can have on student outcomes, including strengthened student science self-efficacy and increased science achievement. Building awareness and support in teachers’ sense of efficacy, as well as developing respectful and supportive relationships between educator/facilitator and pupil during the transition to middle school may construct permanence and accomplishment for all in science.  相似文献

Weight is one of the basic concepts of physics. Its gravitational definition accommodates difficulties for students to understand the state of weightlessness. The aim of this study is to investigate the effect of materials based on 5E teaching model and related to weightlessness on science student teachers’ learning. The sample of the study was 9 volunteer student teachers who were in their first grade in Science Teaching Program in Fatih Faculty of Education, Karadeniz Technical University. Both qualitative and quantitative data were gathered to find answers to the research questions. Findings revealed that all physics textbooks reviewed gave gravitational definition of weight. Also the concept of weightlessness hasn’t been covered in high school and some university textbooks. It was determined that before the implementation student teachers had non-scientific explanations about weightlessness. The implementation of the 5E teaching model and materials developed are effective on learning the weightlessness. It is suggested that similar applications can also be used in other physics subjects or in other fields of science.  相似文献

Collaborative digital textbooks – comprehensive materials covering entire curriculums – are developing from being books in pdf format to becoming collaborative digital environments where teachers and students can communicate, engage in feedback and discussions, share and manipulate materials, test knowledge, and monitor results. This study investigates how these digital environments are used in school practice: How are the collaborative tools used to improve learning? Thirteen seventh- and eighth-grade classes, 370 students and 30 teachers in five Swedish secondary schools, were investigated over 1,5 years by means of questionnaires, classroom observations and interviews with teachers and students. Here, questionnaire results are presented, while observations and interviews serve to provide contextual insights. Collaborative tools were very little used; often teachers and students were not even aware of their existence. Most use was individual, students were left alone with the digital material. Students read or listened to the text and did not actively engage in learning by e.g. making notes or marking text. Most teachers did not use the material actively to help students understand and learn, most did not even check student results on automated tests. We conclude that the teachers have not incorporated the new, collaborative design of the digital textbook into their thinking regarding tools for teaching and learning and still regard it as a static book. This suggests that making full use of digital tools requires new ways of thinking of teaching, and that it takes more than providing digital tools to achieve this end.  相似文献

Teachers’ implementation of a problem-based learning (PBL) program was examined to determine both how they assessed student learning and their reasons for these assessment practices. Ten 6th grade science teachers used Alien Rescue, a computer-based PBL module, with their students for approximately three weeks. Interviews, observations, and teacher-developed artifacts were analyzed qualitatively. The results suggest that assessment-related issues impacted the way that teachers implemented this PBL program, with teachers using grades as extrinsic motivators, deemphasizing PBL’ usual focus on student reflection on their process and solutions, and adding assignments to the PBL program in order to provide greater structure for students’ process and help prepare them for standardized tests. Some of these adaptations conflict with practices typically advocated in the literature on PBL. The implications of these results for the design of PBL programs are discussed, with an emphasis on supporting teachers’ (a) local adaptations of PBL materials and (b) professional development through educative components embedded in PBL programs.

The purposes of this study were to examine how well middle school programs support the attainment of key scientific ideas specified in national science standards, and to identify typical strengths and weaknesses of these programs using research‐based criteria. Nine widely used programs were examined by teams of teachers and specialists in research on teaching and learning. Reviewers found that whereas key ideas were generally present in the programs, they were typically buried between detailed or even unrelated ideas. Programs only rarely provided students with a sense of purpose for the units of study, took account of student beliefs that interfere with learning, engaged students with relevant phenomena to make abstract scientific ideas plausible, modeled the use of scientific knowledge so that students could apply what they learned in everyday situations, or scaffolded student efforts to make meaning of key phenomena and ideas presented in the programs. New middle school science programs that reflect findings from learning research are needed to support teachers better in helping students learn key ideas in science. The criteria and findings from this study on the inadequacies in existing programs could serve as guidelines in new curriculum development. © 2002 Wiley Periodicals, Inc.

This study developed, validated, and utilized the Technology Integrated Classroom Inventory (TICI) to examine technology-integrated science learning environments as perceived by secondary school students and teachers. Using technology-oriented classroom climate instruments and considering the science classroom’s characteristics, TICI was developed. More than 1,100 seventh through ninth grade science students validated the instrument, revealing eight scales: technological enrichment, inquiry learning, equity and friendliness, student cohesiveness, understanding and encouragement, competition and efficacy, audiovisual environment, and order, with alpha reliabilities ranging between 0.69 and 0.91 (0.93 for the entire questionnaire). In measuring actual and preferred learning environments, TICI results indicated that both students and teachers ranked equity and friendliness highest. The largest actual–preferred discrepancy was order (students) and inquiry learning (teachers). TICI offers additional utilities for technology-enriched science leaning environments.  相似文献

Teacher Learning of Technology Enhanced Formative Assessment   总被引：1，自引：1，他引：0  
This study examined the integration of technology enhanced formative assessment (FA) into teachers’ practice. Participants were high school physics teachers interested in improving their use of a classroom response system (CRS) to promote FA. Data were collected using interviews, direct classroom observations, and collaborative discussions. The physics teachers engaged in collaborative action research (AR) to learn how to use FA and CRS to promote student and teacher learning. Data were analyzed using open coding, cross-case analysis, and content analysis. Results from data analysis allowed researchers to construct a model for knowledge skills necessary for the integration of technology enhanced FA into teachers’ practice. The model is as a set of four technologies: hardware and software; methods for constructing FA items; pedagogical methods; and curriculum integration. The model is grounded in the idea that teachers must develop these respective technologies as they interact with the CRS (i.e., hardware and software, item construction) and their existing practice (i.e., pedagogical methods, curriculum). Implications are that for teachers to make FA an integral part of their practice using CRS, they must: 1) engage in the four technologies; 2) understand the nature of FA; and 3) collaborate with other interested teachers through AR.  相似文献

Conclusions It is clear that in this particular educational system teachers' and lecturers' subjective assessments of each student on the cirteria given, were based primarily on two subjective impressions of the student; the students ‘academic ability’ and his, or her “motivation for academic work”. A major proportion of the variance on the physics subjective scales could be explained in terms of these two factors. However the factor scores did little to increase the prediction of success in University physics examinations over and above prediction based on school physics examination results. There was some indication that subjective assessments may have a potential use in predicting non-examination ‘attributes’ of importance, for example drop-outs and future career intentions. Undoubtedly much greater reliability and validity of student scores related to objectives needs to be obtained both via examinations and subjective assessments if future studies are to yield really useful student profiles.  相似文献

In this article, we examine urban teachers’ perceptions of school reform models (SRMs) and culturally relevant pedagogy (CRP). In particular, we examined how urban educators altered mandated reform models in the best interests of their culturally and linguistically diverse students. We discuss data from a phenomenological study, which included in-depth interviews and a focus group with seven urban African-American educators. We explore three facets of the intersection of culturally relevant pedagogy and mandated school reforms: (1) Teachers’ use of CRP to empower urban students; (2) Teachers’ beliefs that SRMs hurt African American students more than help them; (3) Teachers’ adaptations of SRMs with culturally relevant practices. Finally, this article explores the implications for practice and policy when culturally relevant teachers struggle to utilize CRP in the implementation of SRMs.  相似文献
