Background: University physics students were engaged in open-ended thermodynamics laboratory activities with a focus on understanding a chosen phenomenon or the principle of laboratory apparatus, such as thermal radiation and a heat pump. Students had access to handheld infrared (IR) cameras for their investigations.

Purpose: The purpose of the research was to explore students’ interactions with reformed thermodynamics laboratory activities. It was guided by the research question: How do university physics students make use of IR cameras in open-ended investigation of thermal radiation as a phenomenon?

Sample: The study was conducted with a class of first-year university physics students in Sweden. The interaction with the activities of four of the students was selected for analysis. The four students are males.

Design and methods: We used a qualitative, interpretive approach to the study of students’ interaction. The primary means of data collection was video recording of students’ work with the laboratory activities and their subsequent presentations. The analysis focused on how IR cameras helped students notice phenomena relating to thermal radiation, with comparison to previous research on students’ conceptions of thermal radiation.

Results: When using the IR camera, students attended to the reflection of thermal radiation on shiny surfaces, such as polished metals, windows or a whiteboard and emissive properties of surfaces of different types. In this way, they went beyond using the technology as a temperature probe. Students were able to discuss merits and shortcomings of IR cameras in comparison with digital thermometers.

Conclusions: With the help of IR cameras, university physics students attend to thermal phenomena that would otherwise easily go unnoticed.  相似文献

Background: Nationally, many public universities have started to move into the online course and program market that was previously associated with for-profit institutions of higher education. Public university administrators state that students seek the flexibility of online courses. But do students want to take courses online, especially freshmen-level science courses perceived to be difficult?

Purpose: This study investigated student views related to the potential of a physics course they were currently enrolled in being offered online.

Sample: This study took place at a large, public, mid-western university and involved students enrolled in either the first or second semester of a face-to-face flipped physics course for engineering technology majors.

Design and methods: Discussions with students during the semester about their online course experiences and expectations were used to develop the concourse and subsequently the Q sample to perform a Q methodology study about students’ views regarding taking physics courses online. Additional statements for the concourse and Q sample were taken from communications with administrators at the university. In this way, the statements sorted by the students included those from students and those from administrators. Factor analysis of the Q sorts resulted in three factors, each representing a unique perspective. Interpretations of these perspectives included the analyses of the Q sorts, the researcher’s interactions with students and administrators, and students’ written responses regarding their previous online course experiences and their sorting decisions.

Results: Three unique student views emerged were named: keeping it real and face-to-face, Online could be ok depending upon the course and instructor, and Online not for STEM classes. Consensus among the views is also discussed.

Conclusions: Overall, students’ views are negative concerning having physics courses, including labs, online and those views conflict with statements expressed by administrators regarding students’ desires for online courses at the university.  相似文献

ABSTRACT

Background: In Slovakia, no relevant information is available about the scientific literacy levels achieved by secondary school students.

Purpose: The objective of the research was to identify the levels of scientific literacy among students in the last year of grammar school and examine to what extent this determined the subject chosen for a school-leaving exam, which is related to a student’s personal preferences, as well as to the student’s profile and preparation for university education.

Sample: The research sample consisted of 221 students from 17 grammar schools located in various regions of Slovakia.

Design and methods: To identify the level of scientific literacy, we applied the Test of Scientific Literacy Skills.

Results: The students achieved the lowest success rate in the skill focused on the identification of the research design elements and its strengths and weaknesses. A comparably low success rate was also observed in the skill focused on the justification of the conclusions based on quantitative data. Other difficulties were identified in the field of understanding the basics of statistics, thus indicating an insufficient level of mathematical literacy of the students in the abovementioned field. By contrast, the highest success rate was achieved in the skill focused on the correct application of the scientific results for social purposes.

Conclusions: At the end of secondary school studies, the scientific literacy among Slovak students is at the average level. No differences were observed in terms of gender. In terms of the subjects chosen by the students for their school-leaving exams, we observed that those students who took a school-leaving exam in Biology or Chemistry achieved significantly better results in the test. By contrast, the students who reported on Geography and Civics as the subject of their school-leaving exam achieved significantly worse results in the test.  相似文献

ABSTRACT

Background: In England, practical work is a major part of secondary school science and yet little research has examined students’ attitudes specifically to practical work.

Purpose: To examine students’ attitudes to practical work in biology chemistry and physics in secondary schools in England.

Sample: The study involved 607 students from Year 7 to Year 10 (aged 11–15) drawn from three state-maintained secondary schools in England. The schools were, broadly speaking, representative of schools in England in terms of academic measures such as GCSE outcomes, value-added performance and socio-economic area.

Design and methods: The research considered students’ attitudes in terms of an established analytical framework incorporating the affective, behavioural and cognitive (ABC) domains and used a mixed methods approach involving questionnaires, lesson observations, and focus group discussions.

Results: Whilst secondary students’ attitudes to practical work were, generally speaking, positive they were not constant and homogenous but change over time. The affective value of practical work was found to vary by subject although in all three sciences this value decreased, albeit at different rates, as students approached their General Certificate in Secondary Education examinations (GCSE) taken at age 16.

Conclusion: The affective value of practical work needs to be considered on a subject by subject basis, rather than, as is often the case currently in school, in terms of a generic attitude to science practical work. Furthermore, the affective value of practical work can be maximised by using more at the start of secondary education (Key Stage 3 – ages 11–14) with a gradual, subject-specific, reduction as students approach their summative public examinations (age 16) when their preference for non-practical, exam orientated, teaching increases.  相似文献

Background: The active involvement of learners as critical, reflective and capable agents in the learning process is a core aim in contemporary education policy in Australia, and is regarded as a significant factor for academic success. However, within the relevant literature, the issue of positioning students as agents in the learning process has not been fully examined and needs further exploration.

Purpose: This study aims to explore ways in which aspects of self-regulated learning theory may be integrated with the concept of agentic engagement into classroom practice. Specifically, the study seeks to scaffold students’ self-assessment capabilities and self-efficacy by using a formative assessment-as-learning process. The research examines how scaffolded planning, as part of the forethought phase in the Assessment as Learning (AaL) process, influences self-regulation and student agency in the learning process.

Sample: 126 students from school years two, four and six (student age groups 7, 9 and 11 years), and 7 teachers at an independent (co-educational, non-religious) primary school in the Northern Territory, Australia, participated in the study.

Design and methods: Conducted as a one-setting, cross-sectional practitioner research study, the data sources included students’ planning templates, writing samples, interviews with students and teachers and email correspondence with teachers. The data were analysed for emerging themes and interpreted from a framework of social cognitive theory.

Findings: In this study, students were given the opportunity and support to exercise agentic engagement. Findings suggested that, in particular, students who were identified by their teachers as low-achieving and/or with poor motivation, were perceived by the teachers as exceededing expectations by demonstrating relatively greater motivation, persistence, effort and pride in their work than would be the case usually.

Conclusions: The findings from this formative AaL study suggest that AaL has the potential to help scaffold primary students’ development of assessment capabilities.  相似文献

ABSTRACT

Background: STEM education has become a focus of research and teaching interest in recent years. However, not all scholars agree on the definition and purpose of STEM education. This paper summarizes related past research and suggests that, according to the requirements of Taiwan’s educational environment, STEM education should focus on the cultivation of middle school students’ attitudes toward technology and their ability to engage with technological inquiry.

Purpose: The purpose of this study is to explore the effects of STEM education on attitudes toward technology and technological inquiry abilities of middle school students, this study used the 6E Learning byDeSIGN? model proposed by the International Technology and Engineering Educators Association in the US to design a 6E-oriented STEM practical activity.

Sample: The sample of the study consisted of 139 seventh-grade students from six different classes who participated in a practical activity related to egg protection devices.

Design and methods: To achieve this research purpose, a quasi-experimental design was used, with pre-treatment and post-treatment evaluations of each group. Both the experimental and control groups participated in the activity; however, the experimental group students were guided through the activity using a 6E teaching strategy, whereas the control group students were guided using a problem-solving teaching strategy.

Results: The results showed that a 6E teaching strategy had a positive effect on middle school students’ attitudes toward technology and technological inquiry abilities, but these effects were not statistically different from the effect on the control group with problem-solving teaching strategy.

Conclusions: This study indicates there is no significant advantage in using a 6E process over a problem solving approach. Technology teachers aiming to improve students’ attitudes toward technology and their technological inquiry abilities consider refining the 6E-oriented STEM practical activity process, and students may demonstrate better performance in these two areas.  相似文献

Background: Students’ daily-life experiences may render favorable effects on the students’ affective domain like interest, enthusiasm, motivation, joy, curiosity, awareness, and eagerness to learn science as not commonly found in the classroom environment. However, no rigorous research has been reported on those aspects in Mainland China despite many recent studies done in various Western countries.

Purpose: This paper aims to report and compare the science-related experiences of ninth-graders from two places (in Urumqi City of Xinjiang province and Shanghai) in China through a large-scale survey of their junior secondary three students.

Sample: The sample consists of 4115 students in Urumqi City (from 28 schools) and Shanghai (from 25 schools).

Design and methods: This study adopted a Likert scale questionnaire instrument, as translated from the international Relevance Of Science Education (ROSE) Project. From a confirmatory factor analysis of the data, we identify and focus on six factors which are directly correlated with students’ science-related experiences outside school environment in Xinjiang and Shanghai and employ relevant factor scores to compare the gender, regional, and socioeconomic effects.

Results: As revealed by the t-test, gender and regional differences were statistically significant in affecting (1) students’ outdoor living experience, (2) hands-on experience of transportation, and (3) their daily-life experience with do-it-yourself tools and models. In all three aspects, boys and Xinjiang students possessed richer experiences than girls and Shanghai students, respectively.

Conclusions: Based on ANOVA tests, Shanghai students’ out-of-school science-related experiences were more often significantly affected by various socioeconomic variables (including their parents’ education and occupation and their family income) than Xinjiang students. From cross-regional comparison, Chinese students had much fewer science-related experiences than those of Greek and Finnish students. The limitations and educational implications of the present study are also discussed.  相似文献

ABSTRACT

Background: The primary-secondary transition is recognised as a challenging time for students, and poor transition processes can negatively affect the students’ development. School professionals play an important role in enhancing the students’ transition experience, but international literature calls for more research concerning their perspective on this transition.

Purpose: The aim of this study was to investigate what lower secondary school leaders and teachers in Norway emphasise when supporting the primary to lower secondary school transition.

Methods: A qualitative single case study approach was used. The participants were ten form teachers, their team leader and the principal (n = 12) within one lower secondary school. These were the individuals overseeing the transition process on behalf of a cohort of students who transferred to their school in August 2017. Data were collected through observations and focus group interviews. The data were transcribed and analysed qualitatively, inspired by the constant comparative method of analysis.

Findings and conclusion: Framed by their own experiences, the leaders and teachers emphasised ensuring predictability, establishing a safe psychosocial learning environment, giving the students time to learn to be lower secondary school students, and collaboration at the school level and with the families. These efforts are largely in line with what the research recommends. The findings indicate, however, that the teachers need more support during this process. The article concludes that a closer dialogical interaction with colleagues at the primary and secondary levels, parents and students could support the leaders and teachers to promote an even better transition.  相似文献

ABSTRACT

Background: Outdoor learning and computer-based learning are two different alternatives to in-class conventional teacher-centered learning.

Purpose: This study compares the outdoor learning setting with computer-based learning in class. It examines the influence of the two different learning settings on academic achievements, the learning experience, and pro-environmental perceptions.

Sample: A total of 90 elementary school students (third and fourth-grade classes) participated in the study.

Design and methods: The academic knowledge of the study participants was tested through identical exams for both learning settings. In addition, in each group the students’ perceptions were examined by means of a questionnaire about environmental values and the learning experience.

Results: The study demonstrates that academic achievements in the two settings were similar, but the students expressed more enthusiasm about the outdoor learning experience than about in-class learning. In addition, the outdoor learning setting contributed more to promoting positive environmental perceptions even though students did not learn directly about environmental issues and sustainability.

Conclusions: These findings suggest that learning in the natural environment is valuable: Alongside the fostering of computerized learning, it is also important to promoteoutdoor learning settings and integrate both settings by implementing mobile technologies in the outdoor teaching.  相似文献

Background

Measuring the student experience is becoming increasingly important in higher education in the UK. Student experience surveys are used as indicators of quality and form the basis of rankings of higher education institutions. They are also used by them as tools to assist their quality enhancement initiatives. However, these surveys frequently suffer from low response rates, which can reduce the reliability and usefulness of their data. The UK Postgraduate Taught Experience Survey (PTES) is a relatively new survey and suffers from a low response rate. As this survey is new, little is known about why students do not respond to it.

Purpose

This study aimed to explore the reasons why postgraduate students do not respond to the PTES.

Sample

Three hundred and fifty-five postgraduate taught students from four health faculties in one UK higher education institution completed an online survey. Of these, seven participated in one of two focus groups.

Design and methods

The online survey was completed both by students who completed the PTES in 2011 and those who did not. This provided us with cross-sectional data to compare both groups’ knowledge of PTES and their reasons for completing or not completing it. We used multivariate regression analysis to explore which variables were associated with response to PTES. We led two focus groups to explore the themes that emerged from the survey in more depth. This data was analysed by two researchers using thematic analysis.

Results

The cross-sectional data found that students who were not clear about the purpose of PTES were less likely to respond, independent of other potential predictor variables. Focus group data indicated that if postgraduate students felt a stronger connection to the university community they may be more likely to respond to PTES.

Conclusions

This study suggests that higher education institutions may wish to review their strategies for advertising student experience surveys to focus more on their purpose rather than their impact.  相似文献

Background: It is widely agreed that more needs to be done to improve participation in science, technology, engineering and mathematics (STEM). Despite considerable investment in interventions, it has been difficult to discern their effectiveness and/or impact on participation.

Purpose: This paper discusses findings from a six-week pilot STEM careers intervention that was designed and overseen by a teacher from one London girls’ school. We reflect on the challenges for those attempting such interventions and the problems associated with evaluating them.

Sample: Data were collected from Year 9 students (girls aged 13–14 years) at the school.

Design and methods: Pre- and post-intervention surveys of 68 students, classroom observations of intervention activities, three post-intervention discussion groups (five or six girls per group) and a post-intervention interview with the lead teacher were conducted.

Results: Although the intervention did not significantly change students’ aspirations or views of science, it did appear to have a positive effect on broadening students’ understanding of the range of jobs that science can lead to or be useful for.

Conclusions: Student aspirations may be extremely resistant to change and intervention, but students’ understanding of ‘where science can lead’ may be more amenable to intervention. Implications are discussed, including the need to promote the message that science is useful for careers in and beyond science, at degree and technical levels.  相似文献

This study investigated Indonesian and Japanese senior high-school students’ understanding of electrochemistry concepts.

Sample

The questionnaire was administered to 244 Indonesian and 189 Japanese public senior high-school students.

Design and methods

An 18-item multiple-choice questionnaire relating to five conceptual categories (reactions occurring during electrolysis, differences between electrolytic and voltaic cells, movement of ions in voltaic cells, poles in voltaic cells, voltaic cell reactions) was administered.

Results

The findings of this study show that difficulties and alternative conceptions previously reported in the literature are held equally by students from a developing and developed country, Indonesian and Japan respectively.

Conclusions

Collectively, the findings suggest that students’ understanding of electrochemistry concepts is relatively weak. Students from both samples shared common difficulties and displayed several alternative conceptions dealing with electrolysis, electricity flow, the voltaic cell and the electrode reactions. Not surprisingly, the students displayed limited consistency in understanding of the concepts in the five categories. This study has implications for teaching and learning, particularly in classroom discussions using models and computer animations in order to reinforce understanding at the sub-microscopic level.  相似文献

Background: This article describes the design and the evaluation of a student lab program on the topic of nanoscience and technology (NST), mainly focusing on Nanoscience and its applications. The program was designed for students in grades 8–10 and was part of a larger outreach program of the Collaborative Research Center ‘Function by Switching’ at Kiel University. The Model of Educational Reconstruction (MER) served as a framework for the research-based design of the student lab.

Purpose: We aimed to develop an authentic science activity in the area of NST in order to support scientific inquiry learning and to provide a deeper understanding of scientific topics.

Sample: A total of 154 secondary school students from grades 8–10 of seven different secondary schools participated in this study.

Design and methods: A pre-post questionnaire with six subscales on students’ perceptions of the Nature of Science (NOS), Scientific Inquiry (NOSI) and the involved scientists (NOST) in the area of nanoscience and nanotechnology was applied.

Results: Results show that the applied explicit and reflective approach embedded in the nanoscience content significantly improved the participating students’ perceptions of NOS, NOSI and NOST facets. After the lab visit, students’ answers corresponded to a more adequate perception of today’s science and scientists. Some gender differences in learning gains were also detected.

Conclusion: The study served its main purpose which was to investigate a well-balanced strategy to develop authentic out-of-school-learning environments with a focus on NOS/NOSI/NOST. Testing students’ perceptions of the nature of nanoscience provided insights into students’ worlds and served as feedback for the lab program. The outcomes of this study might help to better understand and further develop authentic (nano)science programs in out-of-school settings and science outreach programs.  相似文献

Background : The Trends in International Mathematics and Science Study (TIMSS) assesses the quality of the teaching and learning of science and mathematics among Grades 4 and 8 students across participating countries.

Purpose : This study explored the relationship between positive affect towards science and mathematics and achievement in science and mathematics among Malaysian and Singaporean Grade 8 students.

Sample : In total, 4466 Malaysia students and 4599 Singaporean students from Grade 8 who participated in TIMSS 2007 were involved in this study.

Design and method : Students’ achievement scores on eight items in the survey instrument that were reported in TIMSS 2007 were used as the dependent variable in the analysis. Students’ scores on four items in the TIMSS 2007 survey instrument pertaining to students’ affect towards science and mathematics together with students’ gender, language spoken at home and parental education were used as the independent variables.

Results : Positive affect towards science and mathematics indicated statistically significant predictive effects on achievement in the two subjects for both Malaysian and Singaporean Grade 8 students. There were statistically significant predictive effects on mathematics achievement for the students’ gender, language spoken at home and parental education for both Malaysian and Singaporean students, with R 2 = 0.18 and 0.21, respectively. However, only parental education showed statistically significant predictive effects on science achievement for both countries. For Singapore, language spoken at home also demonstrated statistically significant predictive effects on science achievement, whereas gender did not. For Malaysia, neither gender nor language spoken at home had statistically significant predictive effects on science achievement.

Conclusions : It is important for educators to consider implementing self-concept enhancement intervention programmes by incorporating ‘affect’ components of academic self-concept in order to develop students’ talents and promote academic excellence in science and mathematics.  相似文献

Background: Globalisation trends such as increased migration to and within European countries have led to even greater cultural diversity in European societies. Cultural diversity increases the demand of cultural competency amongst professionals entering their work field. In particular, healthcare professionals need knowledge and skills to equip them to work with clients from different cultural backgrounds. Within higher education (HE), the professional development of cultural competency should ideally feature in undergraduate education and is often promoted as a by-product of a study abroad period. However, recognising that logistical and financial barriers often exist for extended study abroad, one alternative approach could be participation, at home or abroad, in a short-term international programme set within students’ own HE institutions.

Purpose: The aim of this study was to explore HE students’ experiences of participating in international ‘short-term mobility week’ programmes at three European universities.

Methods: Each university involved in the research offered short-term programmes for healthcare professions students at their own institution, where both local students and students from abroad could participate. Participants were healthcare students in the programme at one of the three universities. Data were collected through focus group interviews (4–8 students per group; n = 25). The data were transcribed and then analysed qualitatively, using a content comparison method.

Results: The analysis identified six categories, which reflected students’ journeys within the short-term international experiences.

Conclusions: The analysis suggested that, for these students, engagement in a short-term mobility week programme provided valuable opportunities for encounters with others, which contributed to personal and professional development, greater confidence in the students’ own professional identities, as well as an increasing sense of cultural awareness.  相似文献

ABSTRACT

Background: As inquiry-based instruction is not universally implemented in science classrooms, it is crucial to introduce instructional strategies through the use of contextualized learning activities to allow students with different background knowledge and abilities to learn the essential competencies of scientific inquiry and promote their emotional perception and engagement.

Purpose: This study explores how essential scientific competencies of inquiry can be integrated into classroom teaching practices and investigates both typical and gifted secondary students’ emotional perception and engagement in learning activities.

Sample: A case teacher along with 226 typical and 18 gifted students from a suburban secondary school at Taiwan participated in this study.

Design and methods: After attending twelve 3-hour professional development workshops that focused on scientific inquiry teaching, the case teacher voluntarily developed and elaborated her own teaching activities through the discussions and feedback that she received from workshop participants and science educators. Quantitative and qualitative data were collected through activity worksheet, questionnaire, video camera, and tape recorders. Frequency distribution, Mann-Whitney U test, and discourse analysis were used for data analyses.

Results: Case teacher’s teaching activities provide contextual investigations that allow students to practice making hypotheses, planning investigations, and presenting and evaluating findings. Students’ learning outcomes reveal that typical students can engage in inquiry-based learning with positive emotional perception as well as gifted students regardless of their ability level. Both gifted and typical students’ positive emotional perception of and active engagement in learning provide fresh insight into feasible instructions for teachers who are interested in inquiry-based teaching but have little available time to implement such instructions into their classrooms.

Conclusions: The results of our work begin to address the critical issues of inquiry-based teaching by providing an exemplary teaching unit encompassing essential scientific competencies  相似文献

Background: Investigating factors contributing to chemistry achievement is important since it enables us to make more concrete instructional decisions related to improving students? chemistry achievement.

Purpose: This study aimed to investigate how students? perceptions of learning environment, self-efficacy and gender are related to chemistry achievement.

Sample: Three hundred fifty six high school students with the age range of 14 and 19 from three different schools in the same district were the participants.

Design and methods: A structural equation model was designed and tested. Constructivist learning environment survey, self-efficacy scale were the instruments of the study. Information about students? gender and their chemistry grades belonging to the previous semester were also collected.

Results: The model testing showed that chemistry self-efficacy beliefs, students? perceptions of constructivist learning environment (through chemistry-self efficacy) and gender were significantly related to chemistry achievement. Moreover, the findings showed that students? chemistry self-efficacy beliefs mediated the relation of students? learning environment perceptions to their chemistry achievement.

Conclusions: The present study has some educational implications for teachers, teacher educators and curriculum developers. First of all, self-efficacy was found to have an effect on students? achievement. Therefore, teachers should consider students? self-efficacy beliefs and devise their instruction accordingly. Another implication of this study is the necessity of considering gender differences in designing teachers? instruction.  相似文献

Abstract

The significant interplay between self-efficacy, autonomy support and approaches to learning in adolescent students is widely recognized. However, less is known about whether substantial differences exist between early and middle adolescent students from schools with different environments. To close this research gap, this study used latent mean comparison and multigroup structural equation modeling with questionnaire data from a sample of German adolescent students (N?=?1153; MAgeT1?=?13.97, SD = 1.37; MAgeT2?=?14.27, SD = 1.25) in two waves. Multigroup structural equation modeling reveals that autonomy functions as a mediator in the association between self-efficacy and approaches to learning only for students from schools with a student-centered learning environment based on competence-matrices in contrast to a teacher-directed learning environment, particularly for early adolescent students. More specifically, adolescents’ approaches to learning can be enhanced through autonomy-supportive learning independently of their self-efficacy.  相似文献
