Purpose: This study aims to develop a NOSvs for assessing prospective teachers’ views of the nature of science and to analyse their psychometric properties.
Sample: A total of 565 prospective teachers participated in the study.
Design and methods: The Kaiser–Meyer–Olkin (KMO) Index and Bartlett’s Sphericity Test were used in this study. Confirmatory factor analysis (CFA) was performed to determine the construct validity of the scale. Cronbach’s Alpha (α) coefficient was calculated for the reliability of the study.
Results: It was consequently found that the KMO was larger than .50. That Bartlett’s Sphericity Test was also statistically significant. The items with item-total correlations smaller than .30 were removed from the scale. Cronbach’s α values calculated for each sub-scale were above .70. In consequence of the first CFA performed, fit indices were found to be below the expected level. For this reason, three more items with the least item-total correlations were removed from the scale. Following the CFA, the final form of the scale included 36 items and five sub-scales. 相似文献
Slightly more than an average proportion of staff in the Social Sciences report good teaching practices. They are highly committed to promoting student independence, experience a fairly high level of teaching‐research synergy and have high intrinsic academic motivation. There is large‐scale consensus among Arts staff with university Arts academics scoring highest on promoting student independence, academic motivation, and teaching‐research synergy, and academics in CAE Arts departments scoring highest of all on good teaching practices.
Science staff seem to have different academic values and practices. Their academic motivation is about “average”, and fewer science academics report good teaching practices or practices that promote student independence. In their own work they also experience less teaching‐research synergy. Engineering staff show the lowest academic motivation, least commitment to student independence, experience least teaching‐research synergy, and report below average good teaching practices.
Health Science staff are akin to staff in Arts and Social Sciences in areas concerned with students, e.g. good teaching practices and promotion of student independence. In the areas which tap into their values as academics, e.g. academic motivation and teaching‐research synergy, they seem to be more like science and engineering staff.
Commerce/Law staff were on all aspects somewhere in the middle. 相似文献
Purpose: In the current study, the purpose was to investigate the relations among perceived teacher affective support (PTAS), academic emotions (academic enjoyment, academic anxiety, and academic hopelessness), academic self-efficacy and behavioural engagement in elementary school science classrooms in Turkey.
Sample: A total of 633 fourth- and fifth-grade students in eight elementary schools in Istanbul, Turkey were participated in the study.
Design and methods: A self-report questionnaire was administered to participating students. The data were analysed using structural equation modelling.
Results: Findings showed that PTAS was both directly and indirectly related to the given variables. PTAS was found to be significantly positively associated with students’ academic enjoyment, academic self-efficacy and behavioural engagement and significantly negatively related to their academic anxiety and academic hopelessness in science classrooms. An important finding is that the total effect of PTAS on behavioural engagement, a factor strongly associated with academic success in all disciplines, was as strong as the effect of students’ perceived academic self-efficacy beliefs in science.
Conclusions: Findings suggest that PTAS may help promoting positive emotions and motivation among students in science classrooms, eventually leading to more desirable attitudes and achievement outcomes in science. Teacher affective support deserves greater recognition from researchers, educational policy-makers, administrators and teachers to build better learning conditions for all students. 相似文献
Purpose: The purpose of the study was to investigate the effectiveness of using case-based learning instruction to increase pre-service primary teachers’ chemistry motivation and improve their attitudes toward chemistry as a school subject.
Sample: The subjects of this study consisted of 51 (20 female, 31 male) freshman primary pre-service teachers from an urban university in Turkey. The mean age of the primary pre-service teachers was 21.
Design and methods: One group pre-test and post-test design was used. A chemistry motivation questionnaire and chemistry attitude scale were used for data collection. For the data analysis, two-way repeated measures of ANOVA and repeated measures MANOVA were conducted.
Results: The results indicated that the mean of the attitude score after the treatment was significantly greater than the mean of the attitude before the treatment. The results also demonstrated that there is no significant difference between females and males. According to the results of the study, there is no significant difference between primary pre-service teachers’ chemistry motivation. However, some chemistry motivation constructs mean scores are greater after the treatment.
Conclusions: In sum, it could be stated that case-based learning is helpful for the development of students’ chemistry motivation and attitudes toward chemistry. 相似文献
The final 35 items, adapted from the instrument developed by Doherty & Travers, were subject to a factor analysis. Five interpretable factors were extracted.
The factors were labelled (1) External Monitory, (2) External Professional, (3) Internal Professional, (4) Facilitative‐Constraining, and (5) Internal Professional Peers. These factors represented 32 items with three items unassignable to any factors. Interitem reliability of the factors was judged good. Though the British study also extracted five factors (from a 30 item pool), dissimilarities in labelling and ranking importance occurred. Some of the key differences were traced to the structure of the American educational setting. 相似文献
The four areas of non‐academic development considered were: the young people's rating of their own ability in English, mathematics, science and practical subjects, their academic motivation, their plans for further education and occupational aspirations and their behaviour at school. However, in general there were no differences in any of these respects between children in streamed, setted and mixed‐ability schools.
The implications of these findings are discussed, in particular the potential differences which could arise between schools with different policies if more appropriate methods of teaching and organisation were adopted. 相似文献
Purpose This study explores the construction of different instruments for measuring science skills by categorizing items systematically on three subskill levels (science-specific, thinking, metacognition) as well as on different steps of the empirical cycle.
Sample The study included 128 fifth and sixth grade students from seven primary schools in the Netherlands.
Design and method Seven measures were used: a paper-and-pencil test (PPT), three performance assessments, two metacognitive self-report tests, and a test used as an indication of general cognitive ability.
Results Reliabilities of all tests indicate sufficient internal consistency. Positive correlations between the PPT and the three performance assessments show that the different tests measure a common core of similar skills thus providing evidence for convergent validity. Results also show that students’ ability to perform scientific inquiry is significantly related to general cognitive ability. No relationship was found between the measure of general metacognitive ability and either the PPT or the three performance assessments. By contrast, the metacognitive self-report test constructed to obtain information about the application of metacognitive abilities in performing scientific inquiry, shows significant – although small – correlations with two of the performance assessments. Further explorations reveal sufficient scale reliabilities on subskill and step level.
Conclusions The present study shows that science skills can be measured reliably by categorizing items on subskill and step level. Additional diagnostic information can be obtained by examining mean scores on both subskill and step level. Such measures are not only suitable for assessing students’ mastery of science skills but can also provide teachers with diagnostic information to adapt their instructions and foster the learning process of their students. 相似文献
In designing the summative scales to obtain student feedback, four conditions were seen as important for achieving a system acceptable to both lecturers and students. These conditions—length of scale, time to complete the scale, face validity of the scale and the acceptability of the procedures used to distribute the scales, together with the context within which teaching takes place at the Institution, provided constraints to the design of the summative scales.
Following 98 lecturing and 43 course evaluations, the scales were subjected to a principal factor analysis. This analysis showed that the items most strongly related to overall teaching effectiveness, as assessed by students, included the lecturer's ability to communicate ideas and information and to stimulate interest in the subject.
By pooling student ratings from different teaching situations for any one lecture, a Teaching Performance Profile was prepared. This profile increased the reliability and validity of the information obtained. At the same time it provided a summary suitable for combining with the evaluative . information from the other three sources in making a judgement as to the individual's level of teaching competency. 相似文献
Design/methodology/approach: By applying SDT, we developed two measures. The first one assessed the degree to which the three basic human psychological needs motivate farmers to engage in CDP, and the second concerned farmers’ intrinsic and extrinsic motivation to seek knowledge through participation in CDP. Using data from two samples of farmers, we examined the effect of SDT needs and the influence of the different regulatory styles on individuals’ decision to participate in CDP.
Findings: Our findings indicated that participation in CDP is guided by the most internal forms of human motivation (identified, integrated, and intrinsic motivation), and that deficits in the needs for autonomy and competence predict farmers’ decision to participate in CDP.
Practical implications: These results stress the importance of designing CDP that promote self-directedness, emphasise choice rather than rewards, and generate the conditions that support farmers’ autonomy.
Theoretical implications: Our work suggests that the integration of social psychology into extension/education research can paint a more detailed picture of the way farmers interact with extension/education services.
Originality/value: To the best of our knowledge, this is the first study that uses an SDT framework to examine farmers’ motivation toward participation in CDP. Hence, this research opens a new realm for extension/education research, while it also contributes to the SDT literature by examining the role of self-determined motivation in a different life domain. 相似文献
Objective: This study aimed at testing a hypothesized model of achievement in CS in terms of the learner and the learning environment characteristics.
Method: Data were collected using a questionnaire administered to a random sample of 315 eleventh and twelfth-grade advanced CS students (28% girls). Structural equation modelling (SEM) analysis was utilized to test the proposed structural model.
Findings: The hypothesized structural model fits the data reasonably, yet five of the 17 assumed effects were not significant. A modified model with only significant effects fit the data well and accounted for 41% of the variance. Mathematics achievement, self-efficacy and classroom learning environment are the most influential variables on achievement in CS.
Implications: The findings bear important implication for helping students by resolving obstacles that obstruct their learning and achievement. 相似文献
Purpose: The objective of this study is to determine how parents view science and technology, the factors that influence their views (gender, age, educational level), and the relationship between these opinions and the students’ science academic achievement.
Sample: The present study was conducted with the parents of 169 students attending randomly chosen primary schools in a city in western Turkey.
Design and methods: The ‘Scale for Determining Views of Parents regarding Science and Technology’ (SFDVPAST) was developed by the researchers and used in the present study. The scale’s reliability was 0.88. Data obtained from SFDVPAST were analysed with SPSS 11.5 using frequency (f), percentage (%), average (X), standard deviation (SD), one-way MANOVA, a univariate ANOVA for each dependent variable as a tracking test, and simple linear regression analysis to determine the relationships.
Results: At the completion of this study, findings indicated that gender does not have an impact on how parents view science and technology, but age and educational level do impact parents’ views on this topic. The science academic achievement of the student correlates with the views of his/her parents on science and technology.
Conclusions: Parents’ views towards science and technology have affected their age and education level, but have not affected their sex. In addition, parents’ positive view towards science and technology has affected their science academic achievement of the students. 相似文献
Purpose: The focus of this research is development and testing of a new classroom observation protocol specifically designed for SSI-based instructional contexts.
Design and methods: Development of this SSI-Observation Protocol (SSI-OP) took place in four distinct phases: review of existing protocols and SSI-based instruction frameworks, writing and revision of protocol items, initial testing of the draft protocol, and soliciting feedback from SSI experts.
Sample: Following the four stages of SSI-OP development, we progressed to a series of field tests. The field tests were conducted with three different samples. The first sample was an experienced (10 + years) high school biology teacher and one of her honors biology classes. The second sample consisted of seven Turkish Pre-service Science Teachers (PST) participating in a science methods course. The third sample included two Thai PST from a field experience course embedded within a teacher education program.
Results: The final version of the protocol addressed five dimensions of SSI-based instructional activities: focus of instruction, teaching moves, role of teacher, role of students, and classroom environment.
Conclusions: The SSI-OP could be used in a variety of ways for research including documentation of current practices, impacts of professional development and/or curricula on teaching practices, and changes in teaching over time. We offer the SSI-OP as a new tool with the potential to contribute to science teacher education and research that may advance the teaching and learning of science through SSI. 相似文献
Purpose: This study explores STEM students’ encounters with an interdisciplinary first year. Specifically, motivational patterns towards learning in two introductory courses followed by students from multiple study programmes are investigated.
Sample: 173 Danish undergraduate students enrolled in three science programmes: biomedicine; biochemistry and molecular biology; and physics.
Design and methods: Within the framework of Self-Determination Theory, a measure of autonomous and controlled motivation forms the basis for quantitative analyses (n = 173). A qualitative thematic analysis of students’ open responses further supplements and gives nuance to the findings.
Results: The motivational pattern of physics students is found to differ significantly from that of biochemistry and molecular biology (BMB) students and biomedicine students. The comments reveal that some students struggle to realise the relevance of the course content for their chosen study programme to an extent that makes them reconsider their study choice.
Conclusions: The study offers input to the discussion of how to present inter- and/or multidisciplinarity to students and points to implications on two levels: curriculum design and course content. The findings are of importance to educational planners, decision-makers and teachers dealing with the motivational range that exists within their courses. 相似文献
Purpose: The purpose of this study is to investigate the effect of the REACT strategy of the CBA on remedying 12th grade students’ alternative conceptions of ‘alkenes’ and improving their conceptual understanding.
Sample: The sample of the study consisted of 20 (10 girls and 10 boys – aged 17 to 18 years) 12th grade students who enrolled in the Chemistry course in the 2014–2015 academic year in a public high school.
Design and methods: Since the current study evaluated student gains in conceptual understanding by means of a pre-test, post-test, and delayed-test scores, the study used a single group pre-posttest research design. To gather data, an Alkenes Concept Test (ACT) with 15 multiple choice items and a semi-structured interview protocol with 4 open-ended questions were used. The ACT was administered before and after the intervention as pre- and post-tests. Then, the semi-structured interview protocol was carried out. The ACT was re-administered third time to the students as a delayed-test one month after the intervention.
Results: The results showed that the REACT strategy was effective to remedy the alternative conceptions and helped students to keep new conceptions in their long-term memory one month after the implementation.
Conclusions: The REACT strategy was effective in enhancing conceptual understanding of ‘alkenes’ and helping 12th grade students to link between the scientific concepts and daily life. 相似文献

Results revealed that an almost universal level of support existed for the use of incentives linked directly to good social behaviour and or academic performance. Overall, social outcomes were preferred for good behaviour, and tangible outcomes were preferred for good schoolwork. However, age, sex, and ability effects provided some qualification of these trends. Academic outcomes were very poorly supported throughout. In terms of feedback preferences, overt feedback received significantly more support than covert feedback overall, and was linked significantly more often to social behaviour than schoolwork. This sample also favoured teachers who show empathy and explain well.
The majority of these adolescents indicated that they would like their schools to be redecorated more than any other physical change they could think of, and almost without exception exhibited positive reasons for attending school. 相似文献
Purpose The paper aims to illustrate primary pre-service teachers’ understanding of argumentation based on a study using quantitative methodology. In particular, it aims to illustrate how these teachers view quality of arguments and teaching strategies related to argumentation in the context of a socio-scientific issue on energy.
Sample 332 pre-service teachers enrolled in a university teacher education programme in Spain were investigated. Many studies on argumentation have been conducted with small sample sizes of teachers. Hence, given the sample size, the study provides findings that are likely to be generalisable.
Design and methods A questionnaire was administered to the participants. The design of the questionnaire was guided by some existing analytical tools which were adapted for primary education purposes in the context of socio-scientific issues. This adaptation is novel in that the questionnaire items can potentially be used as diagnostic questions to assess primary teachers’ understanding of argumentation.
Results The results suggest that pre-service teachers had difficulty in understanding arguments and different pedagogical strategies to promote argumentation in classroom. For example, they did not understand the role and the meaning of warrants in scientific arguments and their understanding of the use of different kind of strategies is limited to debates, open discussions and experiments. The age range of the participants and the length of teaching experience had no impact on the quality of their understanding of argumentation.
Conclusions Pre-service science teacher education will benefit from incorporation of more robust and lengthy sessions on argumentation. For example, sessions could focus on quality as well as structure of arguments in science and more diverse pedagogical strategies to support argumentation in science lessons, such as the use of writing frames and presentations. 相似文献
Recall of the items was significantly better following video presentation than after audio‐only presentation; and in the video mode, film items were recalled significantly more often than still picture items, which were in turn recalled significantly more often than no‐picture items. Significant serial position effects occurred across all items in the audio mode, and over still picture and no‐picture items, but not film items in the video mode.
The results are discussed in terms of various imagery hypotheses. 相似文献
Based on a sample of 2,574 students, structural equation modelling is used to test the model. We identify the effect of flow on perceived ease of use, perceived usefulness and on the actual usage of the e-learning environment, demonstrating the importance of this factor as a complement to the components of the TAM. 相似文献
