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
Purpose: Noting the theoretical and practical significance of showing that recognition can support reasoning, the reported research aimed to examine the possibility in relation to horizontal motion.
Sample: The research was conducted with 167 children (mean age = 9.51 years) from Years 4, 5 and 6 of an English-medium school located in Lisbon, Portugal.
Design and methods: Individual pre-tests were administered to all participants to assess initial reasoning about the direction and speed with which rolling balls travel after collision. Reasoning was assessed in the sense of both predicting and explaining. Thereafter, about two-thirds of the sample worked with software that, via simulations of the incorrect patterns that were typically predicted (and comparison with simulations of correct patterns), engaged recognition as feedback on reasoning. The remaining children became an untutored control group. Replicating characteristic computer use in classrooms, half of the software sample worked as singletons with adult guidance available on request and half worked in pairs without the option of guidance. A few weeks later, all participants were post-tested following pre-test procedures.
Results: Pre- to post-test change amongst the children who worked with the software exceeded pre- to post-test change within the control group, and this was observed with both predictions and explanations. The differences were strongest amongst the children who worked as singletons, even though they seldom requested adult support.
Conclusions: Although issues remain to be addressed before the approach can be optimized, its viability as support for reasoning has been demonstrated, and this may have relevance beyond horizontal motion. 相似文献
Purpose: Therefore, the aim of this study is to investigate Swedish technology teachers’ attitudes toward their subject, and how these attitudes may be related to background variables.
Sample: Technology teachers in Swedish compulsory schools (n = 1153) responded to a questionnaire about teachers’ attitudes, experiences, and background.
Methods: Exploratory factor analysis was used to inwvestigate attitude dimensions of the questionnaire. Groupings of teachers based on attitudes were identified through cluster analysis, and multinomial logistic regression was performed to investigate the role of teachers’ background variables as predictors for cluster belonging.
Results: Four attitudinal dimensions were identified in the questionnaire, corresponding to distinct components of attitudes. Three teacher clusters were identified among the respondents characterized by positive, negative, and mixed attitudes toward the subject of technology and its teaching, respectively. The most influential predictors of cluster membership were to be qualified for teaching technology, having participated in in-service-training, teaching at a school with a proper overall teaching plan for the subject of technology and teaching at a school with a defined number of teaching hours for the subject.
Conclusions: The results suggest that efforts to increase technology teachers’ qualifications and establishing a fixed number of teaching hours and an overall teaching plan for the subject of technology may yield more positive attitudes among teachers toward technology teaching. In turn, this could improve the status of the subject as well as students’ learning. 相似文献
Aim: The aim of this article is to compare loneliness, fear of falling, and quality of life in older women who live alone and live with others.
Methods: This cross-sectional study was done on 218 accessible elderly women (116 live alone, 102 live with others) to compare loneliness, fear of falling, and quality of life by using the Farsi versions of UCLA-LS, falls efficacy scale-international (FES-I), and SF12 questionnaires, respectively.
Results: Linear regression was used to compare the means of continuous outcomes between the two groups by adjustment on probable confounder’s age and falling history.
Conclusion: Fears of falling and physical aspect of life quality in the lonely older adults were considerably higher than other group. 相似文献
A stratified random sample of 40 U.S. research university departments, 10 each in physics, sociology, electrical engineering, and education was surveyed by means of a questionnaire.
The major findings of this study suggest that faculty members at research universities express non‐receptive attitudes toward university generic strategies, although, more productive,more satisfied and more committed faculty members are relatively more receptive toward university strategies than less productive, less satisfied and less committed faculty members.
The meaning and the implications of these findings are discussed. 相似文献
Methods: Cross-sectional study with 100 child caregivers of older adults. The data were collected through an interview using the protocol of filial responsibility adapted and validated to Brazilian Portuguese. Filial Expectation and Filial Piety scales evaluated the attitudes of filial responsibility. Caring behaviors assessed were: instrumental support, emotional, financial support, and companionship. The variables that presented p< .20 value in the bivariate analysis were inserted into a multivariate Poisson regression model.
Results: Financial and emotional support behaviors were significantly associated with filial piety (p = .050 and p = .001, respectively) and filial expectation (p = .013 and p = .023, respectively). Providing companionship was associated with filial piety (p = .015).
Conclusion: Attitudes of filial responsibility are associated with some but not all caregiving behaviors. Brazilians caring for older parents show more similarities to Chinese than to Canadian caregivers. Furthermore, filial responsibility and caregiving behaviors are strongly affected by Brazilian social and cultural norms. Reasons are discussed. 相似文献
Strauss and Corbin’s (1990) grounded theory design was employed in this study. A total of eighteen (18) Filipino older adults in nursing homes were purposively selected to participate in one-on-one, semi-structured interviews. These were then transcribed into field texts and analyzed through open, axial and selective coding. Member checking procedure was employed to ensure that the emerged themes were sensible and consistent with the participants’ lived experiences.
Through constant comparative method, the findings of this study presented the development of a three-phase process (Reactivating, Reconstructing and Reframing) that describes the reminiscence experiences of a select group of Filipino nursing home residents. The emergent theoretical model invites nurses as quality care providers to renew and restructure interventions to promote effective reminiscence. 相似文献
Objective: We explored the relationship between students’ first programming languages and both their final grades in an introductory computer science course and their attitudes about programming.
Method: Multiple matching techniques compared those whose first language was graphical (e.g., Scratch), textual (e.g., Java), or absent prior to college.
Findings: Having any prior programming experience had positive effects on both attitudes about programming and grades in introductory computer science courses. Importantly, students whose first language was graphical had higher grades than did students whose first language was textual, when the languages were introduced in or before early adolescent years.
Implications: Learning any computer language is better than learning none. If programming is to be taught to students before early adolescence, it is advised to start with a graphical language. Future work should investigate the transition between different types of programming languages. 相似文献
Purpose The purpose of this study was to investigate the effects of inquiry-based activities on pre-service teachers’ knowledge about GCC and their perceptions of teaching this subject.
Sample The participants were 102 pre-service middle school mathematics and science teachers who were enrolled in an environmental education course.
Design and methods A one group pre-test–post-test design was employed to identify changes after pre-service teachers engaged in a learning unit on GCC. The inquiry-based GCC unit was implemented during the spring semester at a public university in northeastern Turkey. The unit was implemented over seven sessions. Data were collected through two questionnaires: the ‘GCC content questionnaire’ and the ‘perceptions of teaching GCC questionnaire’. Each questionnaire was administered both before and after implementation of the unit. Content questionnaire responses were analyzed using a paired-samples t-test. Responses to the perceptions of teaching questionnaire were analyzed using inductive open coding.
Results Results indicated that after the implementation the pre-service teachers significantly improved their understanding of GCC across all items in the content questionnaire, saw several benefits of and challenges about teaching GCC, and perceived themselves as better prepared to teach about GCC in their future classrooms.
Conclusions Teacher education programs should integrate inquiry-based GCC instruction to increase pre-service teachers’ knowledge as well as their preparedness to teach about this important planetary issue. 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

Purpose: The study was designed to conduct and evaluate the effectiveness of a repertoire of interventions aimed at enhancing secondary school students’ metacognitive capabilities and their achievements in science.
Sample: A class of 35 Year 9 students participated in the study.
Design and methods: The study involved a pre-post design, conducted by the first author as part of the regular designated science programme in a class taught by him.
In order to enhance the students’ metacognitive capabilities, the first author employed clearly stated focused outcomes, engaging them in collaborative group work, reading scientific texts and using concept mapping techniques during classroom instruction. The data to evaluate the effectiveness of the metacognitive interventions were obtained from pre- and post-test results of two metacognitive questionnaires, the Metacognitive Support Questionnaire (MSpQ) and the Metacognitive Strategies Questionnaire (MStQ), and data from interviews. In addition, pre-test and post-test scores were used from a two-tier multiple-choice test on Light.
Results: The results showed gains in the MSpQ but not in the MStQ. However, the qualitative data from interviews suggested high metacognitive capabilities amongst the high- and average-achieving students at the end of the study. Students gains were also evident from the test scores in the Light test.
Conclusion: Although the quantitative data obtained from the Metacognitive Strategies Questionnaire did not show significant gains in the students’ metacognitive strategies, the qualitative data from interviews suggested positive perceptions of students’ metacognitive strategies amongst the high- and average-achieving students. Data from the Metacognitive Support Questionnaire showed that there were significant gains in the students’ perceptions of their metacognitive support implying that the majority of the students perceived that their learning environment was oriented towards the development of their metacognitive capabilities. The effect of the metacognitive interventions on students’ achievement in the Light test resulted in students displaying the correct declarative knowledge, but quite often they lacked the procedural knowledge by failing to explain their answers correctly. 相似文献
Purpose: The aim of this study is to research the effect of PBL implemented in cation analysis experiments in an analytical chemistry laboratory course on students’ level of understanding of the subject of ‘Green Chemistry and Sustainability’.
The study group: The study group consists of second-grade students who participated in an Analytical Chemistry Laboratory within the General Chemistry III course in the Department of Science Education of the Faculty of Education of a state university in Turkey (N = 63).
Design and methods: Quasi-experimental design was used in this research. Students were randomly divided into two groups, an experimental group (N = 31) and a control group (N = 32). Laboratory experiments in which qualitative and quantitative cation group analyses were conducted were carried out in the experimental group with PBL that involved five different scenarios inspired by daily life. In the control group, experiments were performed as closed-ended experiments. The ‘Green Chemistry and Sustainability Test’ (GCST) and semi-structured interviews were used as data collection tools. The independent sample t-test was used in determining whether there was a significant difference between groups by GCST, reviewing pre-test–post-test scores for the control and experimental groups, and semi-structured interviews were analyzed by content analysis.
Results: The results showed that there was a significant difference in favor of the experimental group in GCST post-test scores (t = 10.554, p < 0.05). Considering students’ opinions, there were positive statements, such as that they had taken an active role and had their interest aroused interest since problems in the experiments were related to daily life.
Conclusion: PBL enhanced students’ level of understanding of green chemistry and sustainability subjects and helped them obtain a different perspective in terms of environmental awareness. 相似文献
Purpose: The study investigated the effectiveness of physical models and simulations on students’ understanding daily life applications of electromagnetic induction.
Sample: The nine participants in the study were voluntaries from the fourth year of the physics education undergraduate programme.
Design and methods: Lessons were designed to enhance students’ conceptual understanding of electromagnetic induction. Researchers developed multiple generator and simple electric motor models. These models and simulations about Faraday’s Law, magnetic field, magnets, generator and radio waves were used in lessons. The data were collected through open-ended questionnaire and semi-structured interview. Open-ended questionnaire was employed in a pre-test and a post-test. Students’ answers were categorized as sound understanding, partial understanding, misunderstanding and no understanding. At the end of the last lesson, the interview was implemented about the students’ opinions related to application.
Results: For each question, the number of responses matching the accepted scientific explanation increased after application. The number of illogical or incorrect responses decreased.
Conclusions: Physical models and simulations used in the present study had positive effect on students participated in this study to understand electromagnetic induction and its daily life applications. 相似文献
Purpose/Hypothesis: This mixed-method study examined the impact of an engineering design-based curriculum compared to an inquiry-based curriculum on fifth graders’ content learning of simple machines. We hypothesize that the LEGO-engineering design unit is as successful as the inquiry-based unit in terms of students’ science content learning of simple machines.
Design/Method: We used a mixed-methods approach to investigate our research questions; we compared the control and the experimental groups’ scores from the tests and interviews by using Analysis of Covariance (ANCOVA) and compared each group’s pre- and post-scores by using paired t-tests.
Results: Our findings from the paired t-tests show that both the experimental and comparison groups significantly improved their scores from the pre-test to post-test on the multiple-choice, open-ended, and interview items. Moreover, ANCOVA results show that students in the experimental group, who learned simple machines with the design-based unit, performed significantly better on the interview questions.
Conclusions: Our analyses revealed that the design-based Design a people mover: Simple machines unit was, if not better, as successful as the inquiry-based FOSS Levers and pulleys unit in terms of students’ science content learning. 相似文献
Design/Methodology/Approach: This study was conducted in Ireland using a pre-test, post-test experimental design. All students were instructed on how to complete two skills using either a traditional or blended methodology. They were subsequently assessed to determine their ability to perform the practical skills.
Findings: The findings stressed the suitability of blended learning not only when it was found that there was no significant difference between method of teaching and skill acquisition but also when it was revealed that student demographics had no major influence on skill acquisition.
Practical Implications: It can be concluded that blended learning can be used effectively for the instruction of a diverse range of practical skills in agricultural college and benefit in the successful knowledge transfer to a growing and diverse student population with more emphasis placed on the students taking charge of their own learning environment.
Originality/Value: The article demonstrates the value of blended learning as a successful medium for practical skill attainment within the agricultural college environment.

There is worldwide research concerning the application of social studies to kindergarten. In Greece, specifically, there is no relevant data about this subject.
Therefore, the current study was carried out in order to find out, interalia, I) whether kindergarten teachers occupy students with social studies activities, 2) if they do occupy them, in what social studies activities children engage more frequently and 3) the self‐assessed adequacy of the kindergarten teachers’ training and their attitudes concerning the application of social studies activities to kindergarten.
In order to collect the necessary data for this study, three hundred kindergarten teachers, from urban and non‐urban areas of Greece, were given a questionnaire and the conclusions drawn from their answers form the basis of the study.
In order to gain greater data validity, the recorded answers were cross‐referenced with informal observations in classrooms of teachers who participated in the study. 相似文献
