Abstract This is a multiple‐indicators evaluation of an innovative approach, using self‐paced learning modules accompanying computerised exercises as an adjunct to teaching quantitative concepts and skills to environmental science students at university. The evaluation data, based on a pre‐unit and a post‐unit questionnaire survey completed by 38 students, show high levels of student satisfaction with the unit as a whole, and the self‐paced workbooks in particular. Students also indicated a clear preference for learning from self‐paced workbooks compared to learning from textbooks. Some students applied the quantitative skills acquired to other academic units, or took the initiative to learn to use additional statistical procedures (not covered in the unit) for academic purposes. However, comparison of students’ levels of interest and confidence in quantitative subjects before and after the completion of the unit did not yield significant changes. Implications of the research findings for university science education are discussed. 相似文献

随着基础教育课程改革的逐步深入,教材多样化的趋势越来越明显,中小学教材的品种也越来越多,促进了中小学教材质量的提高,但也出现了重复编写同一水平、同一层次教材的现象。对国内各学科有代表性的教材从学生的学习和发展、对教师教学组织的影响、教师或学生对教材的评价三个维度进行动态比较研究发现,各版本新课标教材都能不同程度地体现新课标要求,追求以学生为本,重视探究活动,强调过程与方法等;各版本新课标教材各有优劣,都有修订和改进的空间,主要问题集中在内容容量不当,难度过大,对学生个体差异性、学校差异性以及地区差异性考虑得不够,各个学段之间缺乏有效衔接等方面,教材编制者应当互相借鉴。 相似文献

新课程社会科教科书在探究设计方面存在着一些误区。教科书编写者往往简单地把探究设计理解为问题设计或者活动设计,大胆地将探究设计作为教科书的主体,却没有在教科书中适当凸显探究程序,只注重探究设计的示范性,而又忽视了探究设计的可操作性。这些失误根源于教科书编写者对社会科教学理论没有深入的研究,同时对国内外社会科课堂教学实践没有深入的了解。这一系列失误无论对教师的探究教学还是学生的探究学习都带来消极影响。 相似文献

Enactment of scientific inquiry in classroom has attracted a great attention of science educators around the world. In this study, we examined two competent teachers’ (one Grade 9 chemistry teacher and one Grade 4 science teacher) enactment of scientific inquiry in selected teaching units to reveal the characteristics of enacted inquiry at different grade levels by analyzing lesson sequence videos. The coding schemes for enacted inquiry consist of ontological properties and instructional practices. Pre-topic and post-topic teacher interviews and the two teachers’ responses to a questionnaire were adopted to identify the factors influencing teacher’s enactment. The results indicate that the two case teachers’ enactment involved a range of inquiry activities. The enacted inquiry at fourth-grade level covered all the inquiry elements, tending to engage students in the whole procedure of inquiry. The ninth-grade chemistry class placed emphasis on the elements “making plans” to solve problems in authentic context. Important factors influencing the enactment include teacher’s understanding about scientific inquiry, textbooks, assessment, students and resource. Implications for inquiry enactment and instruction improvement have been provided. 相似文献

A new learning unit in chemistry, Case-based Computerized Laboratories (CCL) and Computerized Molecular Modeling (CMM) was developed at the Technion. The CCL and CMM curriculum integrates computerized desktop experiments and molecular
modeling with an emphasis on scientific inquiry and case studies. Our research aimed at investigating the effect of the CCL
and CMM learning environment on students’ higher-order thinking skills of question posing, inquiry, and modeling. The experimental
group included 614 honors 12th grade chemistry students from high schools in Israel who studied according to this learning
unit. The comparison group consisted of 155 12th grade chemistry honors students who studied other chemistry programs. Pre-
and post-tests questionnaires were used to assess students’ higher-order thinking skills. Students’ responses were analyzed
using content analysis rubrics and their statistical analysis. Our findings indicated that the scores of the experimental
group students improved significantly in question posing, inquiry and modeling skills from the pre-test to the post-test.
The net gain scores of the experimental group students were significantly higher than those of their comparison peers in all
three examined skills. In modeling skills, experimental group students significantly improved their achievements in making
the transfer from 3D models to structural formulae, but only about half of them were able to transfer from formulae to 3D
models. By presenting a case-based chemistry assessment tool and content analysis of students’ responses in this paper, we
enable teachers and educators to analyze their students’ higher-order thinking skills both qualitatively and quantitatively. 相似文献

This study explores effects of participation by second‐semester college general chemistry students in an extended, open‐inquiry laboratory investigation. Verbal interactions among a student lab team and with their instructor over three open‐inquiry laboratory sessions and two non‐inquiry sessions were recorded, transcribed, and analyzed. Coding categories were developed using the constant comparison method. Findings indicate that, during open‐inquiry activities, the student team interacted less often, sought less instructor guidance, and talked less about chemistry concepts than during their non‐inquiry activities. Evidence suggests that the students employed science process skills and engaged in higher‐order thinking during both types of laboratory activities. Implications for including open‐inquiry experiences in general chemistry laboratory programs on student understanding of science as inquiry are discussed. © 2007 Wiley Periodicals, Inc.

Interviews with representatives of nine municipal agencies involved in air‐quality education were analyzed for concepts and skills perceived as important for citizens in addressing air‐quality concerns. Interviewees focused mainly on general air quality‐related understandings (60.2%), although cognitive skills (22.0%) and specific concepts (17.8%) were also mentioned. The major categories of desired air‐quality understandings identified in interviews included sources, impact, detection, and transport of air pollutants. Identified cognitive skills focused on information‐gathering and ‐evaluating abilities, enabling informed air‐quality decision making. Eight Learning Goal Sets generated from interview data and validated via peer and member checks helped guide a content analysis of six undergraduate liberal arts chemistry textbooks. Overall, sampled chemistry textbooks supported the previously identified air‐quality concepts and skills. However, few textbooks directly confronted interviewee‐reported, air quality‐related misconceptions and inabilities. Instructional and research implications of these validated air‐quality learning goals and subsequent textbook analyses are discussed. © 2007 Wiley‐Liss, Inc. J Res Sci Teach 45: 174–196, 2008. 相似文献

ABSTRACTMany science curricula and standards emphasise that students should learn both scientific knowledge and the skills associated with the construction of this knowledge. One way to achieve this goal is to use inquiry-learning activities that embed the use of science process skills. We investigated the influence of scientific reasoning skills (i.e. conceptual and procedural knowledge of the control-of-variables strategy) on students’ conceptual learning gains in physics during an inquiry-learning activity. Eighth graders (n?=?189) answered research questions about variables that influence the force of electromagnets and the brightness of light bulbs by designing, running, and interpreting experiments. We measured knowledge of electricity and electromagnets, scientific reasoning skills, and cognitive skills (analogical reasoning and reading ability). Using structural equation modelling we found no direct effects of cognitive skills on students’ content knowledge learning gains; however, there were direct effects of scientific reasoning skills on content knowledge learning gains. Our results show that cognitive skills are not sufficient; students require specific scientific reasoning skills to learn science content from inquiry activities. Furthermore, our findings illustrate that what students learn during guided inquiry activities becomes visible when we examine both the skills used during inquiry learning and the process of knowledge construction. The implications of these findings for science teaching and research are discussed. 相似文献

Evidence of a gap in student understanding has been well documented in chemistry: the typical student holds an abundance of misconceptions. The current expectation is that educational reform will foster greater student achievement via inquiry teaching within classrooms. Using assessments involving both conceptual and algorithmic knowledge of gas behaviour, gas laws, and phase changes in chemistry, this study aims to determine the relationship between inquiry teaching and student achievement. The topics were tested in the context of a unit from a reform‐based curriculum that features inquiry, hands‐on activities, and cooperative learning. This curriculum provides step‐by‐step guidance for each lesson in the teacher materials, in order to promote quality inquiry teaching. Two schools were involved in this study, with two high school chemistry teachers from each school. Each teacher participated in professional development and implemented this curriculum with sufficient training and guidance to develop reform methods. Student achievement was found to positively correlate with the use of inquiry teaching about the assessed concepts, regardless of teacher experience or school context. 相似文献

In this study, questions in context-based and traditional chemistry textbooks were analysed from two perspectives that are at the heart of chemistry curricula reforms: a content perspective and a learning activities perspective. To analyse these textbook questions, we developed an instrument for each perspective. In total, 971 textbook questions were analysed. Textbook questions in context-based and traditional curricula appeared to differ significantly in their orientation on content and in the activation to engage students in certain learning activities. Although traditional curricula included more questions that stress traditional chemistry content and included more reproductive chemistry questions than context-based curricula, they were not always as traditional as we had expected. Context-based chemistry curricula focused more on chemistry content relating to societal/technological issues and chemistry theory development and also more questions were included that activate students to regulate their own learning. However, context-based chemistry curricula still included a considerable amount of traditional chemistry content and did not focus as much on higher order learning as we had expected. The developed instruments might be helpful in chemistry curricula design to gain insights into the content which is stressed and how students are activated by textbook questions to engage in learning. 相似文献
