This paper reports an interpretive study that sought students' views about the role that practical work plays in their school science lessons. Twenty-nine students aged between 13 and 16 years were selected from three secondary schools in England. Data were collected from initial lesson observations and in-depth interviews in order to explore students’ views about practical work. The findings suggest that students have three main reasons why practical work is important in their school science lessons: for interest and activity, including social and personal features such as participation and autonomy; as an alternative to other forms of science teaching involving a pedagogy of transmission, and as a way of learning, including memorizing and recall. The findings are discussed in the context of a critical view of previous work on the role of practical work, work on attitudes to science and on the student voice. The paper concludes that practical work is seen to provide opportunities for students to engage with and influence their own learning but that learning with practical work remains a complex issue that needs further research and evaluation about its use, effectiveness and of the role of scientific inquiry as a component of practical activity.  相似文献

Astrobiology is, on a profound level, about whether life exists outside of the planet Earth. The question of existence of life elsewhere in the universe has been of interest to many societies throughout history. Recently, the research area of astrobiology has grown at a fast rate, mainly due to the development of observational methods, and the media is frequently reporting on new research findings. International surveys show that astrobiology questions are among those that interest young people the most. The popularity of astrobiology and the way it captures much science content makes it an interesting area for science teaching. However, there is very little research directly focused upon students’ views in astrobiology. The study reported in this paper draws from the answers of 186 Swedish lower secondary students (16 years old) to a questionnaire, with closed and open-ended questions regarding their views of issues in astrobiology. The study was guided by the worldview theory (Cobern 1991; Cobern, Science Education 80(5):579–610, 1996; Cobern, Science and Education 9:219–246, 2000). The results show that even though basic reasoning in astrobiology is known by a majority of the students, there is a considerable number of students, for whom this is not the case. Furthermore, it was found that for all questions, there are students answering in different ways when asked to describe their own view and the view they associate with science researchers. The implications of the study for further research and for the teaching of astrobiology in science class are discussed.  相似文献

In this work, we examine middle school students?? understanding of the greenhouse effect and global warming. We designed and refined a technology-enhanced curriculum module called Global Warming: Virtual Earth. In the module activities, students conduct virtual experiments with a visualization of the greenhouse effect. They analyze data and draw conclusions about how individual variables effect changes in the Earth??s temperature. They also carry out inquiry activities to make connections between scientific processes, the socio-scientific issues, and ideas presented in the media. Results show that participating in the unit increases students?? understanding of the science. We discuss how students integrate their ideas about global climate change as a result of using virtual experiments that allow them to explore meaningful complexities of the climate system.  相似文献

A large-scale cross-sectional study (N = 4002) was set up to determine Flemish secondary school students’ willingness to eat genetically modified food (WTE) and to link students’ WTE to previously identified key variables from research on the acceptance of genetic modification (GM). These variables include subjective and objective knowledge about genetics and biotechnology, perceived risks and benefits of GM food crops, trust in information from different sources about GM, and food neophobia. Differences between WTE-related variables based on students’ grade level, educational track, and gender were analyzed. The students displayed a rather indecisive position toward GM food and scored weakly on a genetics and biotechnology knowledge test. WTE correlated most strongly with perceived benefits and subjective and objective knowledge. The results have clear implications for education, as they reiterate the need to strengthen students’ scientific knowledge base and to introduce a GM-related debate at a much earlier stage in their school career.  相似文献

This study used Witte's extended parallel process model to examine the relationships between the use of fear appeals and college students’ attitudes and behavioral intentions toward global warming. A pretest-posttest quasi-experimental design was adopted. Three hundred forty-one college students from six communication courses at two universities were recruited for this experiment. The results show that when in a high-threat condition, both high- and low-efficacy messages resulted in positive attitudes and behavioral changes, while in a low-threat condition, low-efficacy messages led to negative changes in attitudes and behavioral intentions. This study suggests that when attempting to promote low carbon-emitting behaviors among college students, messages should contain both threat and efficacy information, but messages that contain low-threat and low-efficacy information should be avoided.  相似文献

One of the challenges of implementing a new curriculum is how to bridge the gap between the underlining principles of the curriculum and the cultural and social orientations of the society which includes teachers and students. This article reports on a study that explored how the cultural and social orientations of teachers and students can influence the implementation of a constructivist curriculum in mathematics classrooms. The data for the study came from 250 students and 41 mathematics teachers, using questionnaires, observations, and interviews. The results showed that inasmuch as mathematics teachers and their students acknowledge the importance of student’s active participation and teamwork, these practices have not been fully conceptualised into the Ghanaian mathematics classroom due to some cultural factors. Two main cultural factors were discovered from the analyses of the results. Firstly, the culture of acknowledging only correct answers in class has a negative impact on individual students’ confidence and participation during mathematics lessons. Also, the culture of teamwork is not fully accepted within Ghanaian classrooms as most students find it difficult working in groups and accepting and appreciating each other’s view. It was evident in all lessons that students were ridiculed by their peers when they provide a wrong answer to a question and this affected individual students’ participation in the classroom. Therefore, we suggested that teachers should be pro-active in promoting a classroom environment which is free from fear and intimidation to motivate students to be actively involved in the classroom discourse.  相似文献

The purpose of this qualitative study was to explore five world language teachers’ beliefs about their students, their attributions about student enrollment, and their reported teaching practices. Findings represent a continuum of critical practice in that three teachers appeared to espouse deficit thinking and stereotypes about students of color, and color-evasiveness or colorblindness as an approach to teaching. Two teachers appeared to espouse beliefs that may be more representative of inclusive classrooms, and these teachers reported advocacy work for certain student groups and efforts to develop students’ critical consciousness in their classrooms. Findings are contextualized via critical lenses, and implications for language teacher education and policy are discussed.  相似文献

Many universities began to explore possibilities of launching campus safety apps beyond blue light emergency towers to improve campus security. However, no previous studies exist regarding whether the apps have more benefits beyond their annual fees, compared to their annual fees of blue light emergency towers. This study conducted a choice experiment to measure students’, faculty’s, and staff’s marginal willingness to pay for a campus safety app at a large public university in the United States. As a result, a total of these groups’ values of the app was shown to be at least $30,205 per year. This result indicated that their values were three times larger than the actual annual fee of the campus safety app, and cost-effectiveness compared to blue light emergency towers.  相似文献

This study explored factors of students’ mental states, including emotion, intention, internal mental representation, and external mental representation, which can affect their learning performance. In evaluating students’ mental states during the science learning process and the relationship between mental states and learning achievement, valid, reliable, and scalable measures of students’ mental states and learning achievement are needed. This paper presents the development of the Mental State Conceptual Learning Inventory (MSCLI) to identify students’ mental states before and after learning about acids and bases. This instrument is time efficient and convenient and can be administered to large student samples so that teachers and researchers can gain profound insights into their students’ learning of acids and bases in science class. The results of this study indicate that students’ mental states are highly correlated with their achievement. As a whole, low-achieving students tended to have negative emotions and low intentions, were not good at internal visualization, and were unable to interpret graphics and draw pictures. In contrast, high-achieving students had positive emotions and intentions when learning life-related topics about acids and bases, and were good at internal visualization and drawing and interpreting graphics.  相似文献

We examined novice teachers’ beliefs about grading and constructivist teaching approaches. Adapting an existing instrument designed to assess preservice teachers’ grading beliefs that deviate from recommended practices, we administered the Survey of Grading Beliefs to 203 inservice teachers. Exploratory factor analysis resulted in a 3-factor model with a structure similar to that found in prior research; differences between the 2 samples were noted. Teachers who endorsed grading beliefs characterized as “academic enabling” tended to endorse constructivist teaching approaches. To better understand the underlying reasoning of the academic enabling factor, we conducted qualitative research with 6 additional teachers. Results revealed that teachers’ reasons for grading judgments were strategic, analytical, and thoughtful, not haphazard. This study provides empirical evidence about the nature of novice teachers’ beliefs about grading, how they relate to constructivist teaching beliefs, and how they may compare to the beliefs of preservice teachers.  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

Using a mixed-methods survey design that was predominantly quantitative, this study explored Asian international students’ willingness to seek counseling. Participants were 177 Asian international students recruited from a U.S. Midwestern University. After controlling for attitudes toward psychological help-seeking and past counseling experience, academic stress was significantly and positively related to willingness to seek counseling for academic problems. Qualitative data were also collected using one open-ended question in the survey: “What comes into your mind when you think about ‘counseling’ or ‘mental health counseling’?” The qualitative analyses revealed positive perceptions of counseling as well as a personal reluctance to seek counseling.  相似文献

The present research was designed to investigate the reaction of secondary school students to the communication code that the press uses in science articles: it attempts to trace which communication techniques can be of potential use in science education. The sample of the research consists of 351 secondary school students. The research instrument is a questionnaire, which attempts to trace students’ preferences regarding newspaper science articles, to explore students’ attitudes towards the science articles published in the press and to investigate students’ reactions towards four newspaper science articles. These articles deal with different aspects of science and reflect different communication strategies. The results of the research reveal that secondary school students view the communication codes used in press science articles as being more interesting and comprehensible than those of their science textbooks. Predominantly, they do not select science articles that present their data in a scientific way (diagrams and abstract graphs). On the contrary, they do select science articles and passages in them, which use an emotional/‘poetic’ language with a lot of metaphors and analogies to introduce complex science concepts. It also seems that the narrative elements found in popularized science articles attract students’ interest and motivate them towards further reading.  相似文献

We re-conceptualized the meaning of scientific literacy and developed an instrument, which we call the Global Scientific Literacy Questionnaire (GSLQ) based on a new conceptual framework for scientific literacy in the twenty-first century. We identified five dimensions, each with key elements. The five dimensions are (1) content knowledge (core ideas of science), (2) habits of mind (science practices), (3) character and values, (4) science as human endeavor, and (5) metacognition and self-direction. In this study, we attempted to diagnose the extent to which South Korean secondary students perceive themselves as global citizens having such capabilities using GSLQ with 3,202 students (7th–12th grades). Validity and reliability were examined using various statistical techniques including the Cronbach's α coefficient, exploratory factor analysis, and confirmatory factor analysis. The use and value of the instrument were discussed by examining the Korean secondary students’ overall scientific literacy as well as their views on each dimension across gender and grade levels. We recommend that teachers and researchers use the GSLQ to assess students’ global scientific literacy and provide comments on its usefulness as a research tool and the practical use of its inventory of items.  相似文献
