This study was a mixed quantitative–qualitative research to evaluate the efficacy of a designed student-centred instructional (DSCI) program for teaching about acids and bases. The teaching innovation was designed based on constructivist, hands-on inquiry and context-based approaches and implemented in seven 45-min lessons with a class of 36 grade 11 students (experimental group) from a public senior high school in Indonesia. Another class of 38 students (comparison group) from the same school was instructed using a traditional teacher-centred approach. Data were obtained using a (1) 12-item achievement test on acids and bases that was administered to both groups as a pretest and a posttest, (2) self-evaluation 13-item questionnaire on students’ perceptions of their competence and confidence in carrying out the inquiry activities that was administered to the experimental group and (3) 3-item open-ended questionnaire on students’ perceptions of the instructional process using the DSCI that was administered to the experimental group. The results of the study showed that the teaching innovation was effective in improving students’ understanding of acid–base concepts with significant difference between the two groups on the posttest mean scores. Moreover, the effectiveness of the innovation was supported by an increase in students’ interest in learning science as indicated by their (1) positive perceptions of their engagement and competence in doing inquiry activities, (2) positive perceptions of the learning environment and (3) positive outcome expectations. The findings have implications for chemistry teaching in any institution with similar achieving students as well as for the professional development of teachers.  相似文献

Teaching and Learning Physics in a 1:1 Laptop School   总被引:1,自引:1,他引:0  
1:1 laptop programs, in which every student is provided with a personal computer to use during the school year, permit increased and routine use of powerful, user-friendly computer-based tools. Growing numbers of 1:1 programs are reshaping the roles of teachers and learners in science classrooms. At the Denver School of Science and Technology, a public charter high school where a large percentage of students come from low-income families, 1:1 laptops are used often by teachers and students. This article describes the school’s use of laptops, the Internet, and related digital tools, especially for teaching and learning physics. The data are from teacher and student surveys, interviews, classroom observations, and document analyses. Physics students and teachers use an interactive digital textbook; Internet-based simulations (some developed by a Nobel Prize winner); word processors; digital drop boxes; email; formative electronic assessments; computer-based and stand-alone graphing calculators; probes and associated software; and digital video cameras to explore hypotheses, collaborate, engage in scientific inquiry, and to identify strengths and weaknesses of students’ understanding of physics. Technology provides students at DSST with high-quality tools to explore scientific concepts and the experiences of teachers and students illustrate effective uses of digital technology for high school physics.  相似文献

Though research has shown that students do not have adequate understandings of nature of science (NOS) by the time they exit high school, there is also evidence that they have not received NOS instruction that would enable them to develop such understandings. How early is “too early” to teach and learn NOS? Are students, particularly young students, not capable of learning NOS due to developmental unreadiness? Or would young children be capable of learning about NOS through appropriate instruction? Young children (Kindergarten through third grade) were interviewed and taught about NOS in a variety of contexts (informal, suburban, and urban) using similar teaching strategies that have been found effective at teaching about NOS with older students. These teaching strategies included explicit decontextualized and contextualized NOS instruction, through the use of children’s literature, debriefings of science lessons, embedded written NOS assessments, and guided inquiries. In each context the researchers interviewed students prior to and after instruction, videotaped science instruction and maintained researcher logs and field notes, collected lesson plans, and copies of student work. The researchers found that in each setting young children did improve their understandings of NOS. Across contexts there were similar understandings of NOS aspects prior to instruction, as well as after instruction. There were also several differences evident across contexts, and across grade levels. However, it is clear that students as young as kindergarten are developmentally capable of conceptualizing NOS when it is taught to them. The authors make recommendations for teaching NOS to young children, and for future studies that explore learning progressions of NOS aspects as students proceed through school.  相似文献

This study examined the effect of computer-assisted instruction (CAI), used as a problem-solving supplement to classroom instruction, on students' understanding of chemical formulas and mole concept, their attitudes toward chemistry subjects, and CAI. The objective was to assess the effectiveness of CAI over recitation hours when both teaching methods were used as a supplement to the traditional chemistry instruction. We randomly selected two classes in a secondary school. Each teaching strategy was randomly assigned to one class. The experimental group received supplementary instruction delivered via CAI, while the control group received similar instruction through recitation hours. The data were analyzed using two-way analysis of variance and t-test. It was found that the students who used the CAI accompanied with lectures scored significantly higher than those who attended recitation hours, in terms of school subject achievement in chemistry and attitudes toward chemistry subjects. In addition, there was a significant improvement in the attitudes of students in the experimental group toward the use of computers in a chemistry course. There was no significant difference between the performances of females versus males in each treatment group.  相似文献

ABSTRACT

The study that is the subject of this paper tested the effects of EDI (explanation-driven inquiry) on students’ redox conceptual understanding and their misconceptions. Two classes of 119 10th grade high school students were involved. Two groups of students in the same school were chosen. One class that was taught by EDI teaching was set as the treatment group and another class that received conventional teaching was set as the control group. Students’ conceptual understanding was measured by a standardised instrument, and the students’ misconceptions were compared. The analysis of covariance showed that EDI teaching had significant effects on students’ redox conceptual understanding, and the results of the chi-square test demonstrated that students’ conceptual understanding level was improved by using EDI teaching. Also, after comparing the two groups of students’ misconceptions of redox, the results indicated that the students’ misconceptions changed toward deeper conceptual understanding in the treatment group that used EDI. Finally, some suggestions were made on how to implement EDI in the classroom.  相似文献

The purpose of the study was to investigate the effectiveness of case-based learning instruction over traditionally designed chemistry instruction on eleventh grade students’ epistemological beliefs and their attitudes toward chemistry as a school subject. The subjects of this study consisted of 63 eleventh grade students from two intact classes of an urban high school instructed with same teacher. Each teaching method was randomly assigned to one class. The experimental group received case-based learning and the control group received traditional instruction. At the experimental group, life cases were presented with small group format; at the control group, lecturing and discussion was carried out. The results showed that there was a significant difference between the experimental and control group with respect to their epistemological beliefs and attitudes toward chemistry as a school subject in favor of case-based learning method group. Thus, case base learning is helpful for development of students’ epistemological beliefs and attitudes toward chemistry.  相似文献

This study explored the role of student characteristics in studying micro teaching–learning environments. The overarching hypothesis is that teachers teach differently to micro environments in their classrooms. This study is the first of a series exploring the following four questions: (1) What student profiles are identified at the beginning of a school year with respect to cognitive and motivational-affective factors? (2) How do students with different profiles perceive conditions in their learning environment? (3) To what degree do classrooms differ in the composition of student profiles? (4) What are possible consequences for examining micro teaching–learning environments? The study investigated 82 randomly selected high school science classrooms. Student characteristics were assessed at the beginning of the school year. After a video taped teaching unit, students were asked to rate the degree to which they experienced learning conditions as supportive. Latent class analysis (LCA) showed five distinct student profiles that varied along cognitive and motivational-affective dimensions. Multilevel analyses showed effects of student profiles assessed at the beginning of the school year on the students’ perception of learning conditions in a teaching unit 4 months later. To illustrate consequences for examining micro teaching–learning environments, student profiles were linked to video examples. The examples point to the special value of LCA in studying micro teaching–learning environments: they make it possible to focus on the individual student and to investigate the interplay of student characteristics and the learning environment.  相似文献

Schools play a crucial role in preparing students for a technology-driven world. Although schools incorporate technology for teaching and learning in promising ways, reviewing their organisational strategies would enhance their digital capacity—namely, the effective integration of technology in teaching and learning practices. This article presents insights for improving schools' digital capacity provided by school leaders, teachers, and students from fourteen European countries, through open-ended questions on the SELFIE online tool for collective reflection. This article presents the thematic analysis conducted on 5247 excerpts collected through SELFIE questionnaires, referring to participants' perceptions of their schools' digital infrastructure, the usefulness of technology for teaching and learning, and the perceived need to make the most of technology. Findings align with international studies, which confirm that schools' digital infrastructure still needs improving, while teachers need more training on embedding technology in their teaching practices. Findings also reveal differences in school leaders, teachers, and students' viewpoints and experiences on technology use in their schools. Comparing viewpoints and experiences regarding a school's digital capacity by using a comprehensive and structured process of collective reflection, the SELFIE tool is unique within the field and can offer insights to school communities, education policymakers and researchers.  相似文献

A research-based framework for teaching science is a heuristic tool used to help preservice teachers conceptualize many complexities of teaching while making explicit the strategy to use a research-based body of professional knowledge to inform instructional decision-making (Clough, 2003, Paper presented at the annual meeting of the Association for the Education of Teachers in Science, St. Louis, MO). Elementary preservice teachers frequently struggle to apply this knowledge to classroom decisions (Madsen, 2002, Paper presented at the annual meeting of the North Central Association for the Education of Teachers of Science, Bettendorf, IA). This study examined the effects of using a video case-analysis within an elementary science methods course focused on the development of a research-based framework. Students in two course sections completed a unit plan, and students in one section completed the video analysis. Video analysis students’ performance on an oral defense with the instructor was compared with oral defense performance from students in the unit plan group. Video analysis students outperformed their peers on questions related to how learning theories influence decisions of selecting content, explaining the use of questioning, and the use of self assessment strategies. Despite these differences, students in both groups still perceive teaching as primarily accomplished through activities and have difficulties understanding the critical role of the teacher in promoting student goals. This study raises issues regarding teachers’ knowledge development during preservice experiences.  相似文献

In this content analysis study, researchers explored middle school students’ preference for playing video games and the possible implications for learning environments. During two-week, summer sessions, learners played videos games and answered questions related to their preferences in different settings. Students’ preferences and justifications for playing alone or in company are described. Results shows that middle school students prefer to work in groups motivated by companionship, collaboration, competition, and challenge. The article concludes showing the relevance of using video games to emphasize 21st century skills in learners.  相似文献

The process of constructing A Portrait of Academic Life web resource has included careful evidence gathering and analysis of student performance necessary to assess learning and give useful feedback to increase the students’ ability to use information effectively in education. The students, too, develop self-assessment and reflective skills as they create online research portfolios. The online resources model new technologyenhanced strategies for teaching and learning that support standards-based teacher education programs in higher institutions. Other artifacts contained in A Portrait of Academic Life include digital video vignettes of students actively completing course assignments and reflecting on the learning process, and instructor reflections on teaching strategies to improve learning outcomes. As a culminating course activity, students showcase their online research portfolios at a gallery walk. The students were tremendously excited to present the wealth of information they have so carefully collected using the powerful technology tools available for their use in the teacher education program at Towson University. The innovation and originality presented in the form of student online research portfolios offered fresh perspectives to the honored guests. Likewise, it will enormously help students and faculty to see examples of the process of transforming traditional research papers into rich, informative online research portfolios.  相似文献

This study explored the understandings of data and measurement that school students draw upon, and the ways that they reason from data, when carrying out a practical science inquiry task. The two practical tasks used in the study each involved investigations of the relationships between two independent variables (IVs) and a dependent variable (DV); in both tasks, one IV covaried with the DV, whereas the other did not. Each was undertaken by 10 students, aged 10, 12, and 14 years (total n = 60 students), working individually. Their actions were video‐recorded for analysis. In a subsequent interview, each student was asked to discuss and interpret data collected by two other students, undertaking a similar (but different) practical task, shown on a video‐recording. An analysis of the sample students' performance on the practical tasks and their interview responses showed few differences across task contexts, or with age, in students' reasoning, but significant differences in performance when investigating situations of covariation and non‐covariation. Few students in the sample displayed sufficient understanding of measurement error to deal effectively with the latter. Investigations of non‐covariation cases revealed, much more clearly than investigations of covariation cases, the students' ideas about data and measurement, and their ways of reasoning from data. Such investigations therefore provide particularly valuable contexts for teaching and research. © 2004 Wiley Periodicals, Inc. J Res Sci Teach 41: 748–769, 2004  相似文献

To enable high school students, especially those interested in art and design-related careers, to improve their ability to integrate knowledge of science, technology, engineering, and mathematics (STEM) in their creative design practices and to be familiar with auto manufacturing, the development of a bridging curriculum, known as STEAM (science, technology, engineering, arts, and mathematics) using digital tools such as 3D printers, has been increasingly recognized as emergent and vital. As a bridging curriculum, it is essential to examine the curriculum with respect to high school and college students to highlight the differences in their knowledge and skills for improving curriculum development. Hence, we conducted a teaching experiment using a CO2-car engineering design curriculum in this study to analyze the learning outcomes of four groups of students (three 3D-printing groups: 108 high school students, 12 design college students, and 12 engineering college students; one handmade group: 36 high school students) to assess their competencies. The results of the present study highlight significant differences in creativity, forecast accuracy, race outcomes, and learning outcomes. Suggestions based on the results were generated to improve the curriculum. The findings in this study serve as a reference for the future design, development, and implementation of STEAM curricula.  相似文献

Conclusions Beginning student teachers have already acquired very definite views about teaching science before they begin their teacher training course. These views are generally similar to the views espoused by science educators, but are contrary to the classroom practices of many teachers. Their views seem to have origins in what the students perceive to have been meaningful and enjoyable learning experiences for themselves in their own schooling; and to a lesser extent for children they have observed. Female students who have studied more science at high school tend to favour the use of worksheets in experimental work. Several interesting questions arise from these findings: When these students begin to teach as qualified teachers, will they still espouse the same opinions? If so, does that mean that there is a ‘new wave’ of teachers entering the service who are more committed to hands-on activity work than their older colleagues? If not, what aspects of the teacher training process have caused them to change their opinions? Will these present students be using hands-on strategies themselves after they have been teaching for some time? That is, do system and school constraints effectively prevent teachers from using such strategies? Can secondary science teachers do more to influence positively their students' opinions about teaching science, such as engendering more positive attitudes to science, incorporating more hands-on work, and relying less on printed worksheets in laboratory work? This exploratory work has highlighted the concern expressed by Morrissey (1981) in that there is a great need for long term longitudinal studies of student teachers' attitudes to teaching science, with a particular focus on their teaching behaviours after graduation.  相似文献

This study compared the efficacy of two cardiac anatomy teaching modalities, ultrasound imaging and cadaveric prosections, for learning cardiac gross anatomy. One hundred and eight first-year medical students participated. Two weeks prior to the teaching intervention, students completed a pretest to assess their prior knowledge and to ensure that groups were equally randomized. Students, divided into pre-existing teaching groups, were assigned to one of two conditions; "cadaver" or "ultrasound." Those in the cadaver group received teaching on the heart using prosections, whereas the ultrasound group received teaching using live ultrasound images of the heart. Immediately after teaching, students sat a post-test. Both teaching modalities increased students' test scores by similar amounts but no significant difference was found between the two conditions, suggesting that both prosections and ultrasound are equally effective methods for teaching gross anatomy of the heart. Our data support the inclusion of either cadaveric teaching or living anatomy using ultrasound within the undergraduate anatomy curriculum, and further work is needed to compare the additive effect of the two modalities.  相似文献

This paper presents a case study about the use of digital comics in teaching modern Greek in high schools (aged 12–13). The ultimate goal of the educational use of digital comics is to promote students’ acquisition of language skills and to help them apply their imaginations and reuse their cultural experiences in creating multimodal comic‐like digital stories. The core idea of this case study, which was conducted at a high school in Greece, was to provide the opportunity to students become authors of their own digital comic stories using an innovative authoring tool called ComicLab.  相似文献
