Adequate response to mail health surveys by minority populations has proved problematic. The impact of mail survey design features utilized to promote Orthodox Jews' responses (N = 138; 82 eligible synagogue member households) to a mailed questionnaire used to measure walking behavior are described and assessed. An examination of response characteristics by wave as an estimate of nonresponse bias and calculations of response speed and cost-effectiveness were conducted. Response rates of 54.8% and 52.9% for eligible households and individuals, respectively, were accumulated by using 9 of 14 recommended mail survey techniques for this particular population (e.g., culturally appropriate salutation and closing, religious iconography, Talmudic aphorisms, and incentives linked to Hebraic numerology and the synagogue's building fund). Nonrespondents most frequently cited business, forgetfulness, or lack of topic salience as reasons for not responding. No differences on sociodemographic items and 9 of 11 continuous variables were observed by response wave; response speed was slowest in response to later mailing waves; and cost-effectiveness was maximal during postcard follow-up (E statistic = 3.74). Nonresponse bias may not be problematic with a > 50% response rate in this particular population. Front-loading incentives may prompt quicker response and improve cost-effectiveness. Specific design considerations for future consideration and testing are provided. 相似文献

We describe the main principles of the framework theory approach to conceptual change and briefly report on the results of a text comprehension study that investigated some of the hypotheses that derive from it. We claim that children construct a naive physics which is based on observation in the context of lay culture and which forms a relatively coherent conceptual system—i.e., a framework theory—that can be used as a basis for explanation and prediction of everyday phenomena. Learning science requires fundamental ontological, epistemological, and representational changes in naive physics. These conceptual changes take a long time to be achieved, giving rise to fragmentation and synthetic conceptions. We also argue that both fragmentation and synthetic conceptions can be explained to result from learners’ attempts assimilate scientific information into their existing but incompatible naive physics. 相似文献

The present study aimed at adapting in the Greek language the Students' Motivation Towards Science Learning (SMTSL) questionnaire developed by Tuan, Chin, and Shieh (INT J SCI EDUC 27(6): 639-654, 2005a) into a different cultural context, a different age group, that is, in university students and with a focus on physics learning. Three hundred and fifty Greek student teachers participated in the study. The original instrument consisted of 35 items allocated in six scales: self-efficacy, use of active learning strategies, science learning value, performance goals, achievement goals, and learning environment stimulation. The instrument's internal consistency was acceptable and comparable to previous studies' reports. Confirmatory factor analysis (CFA) was applied on the data in order to test an a priori hypothesis regarding the SMTSL's factorial structure based on previous studies' findings. The results of the study showed that the six-factor conceptual model of students' motivation proposed by the SMTSL applies in this different cultural setting and in this group of university students with reference to physics learning. Along with the six distinct motivational constructs confirmed, students' motivational beliefs were also explained by a general motivational construct assumed to be at their basis. Suggestions for further improvement of the Greek version of the SMTSL are also discussed. 相似文献

The aim of the present study was to examine the relations of students’ intrinsic motivation in physical education lessons with factors such as perceived locus of causality, perceived competence and outcome expectancies. Five hundred sixteen students of grades 7–12 participated in the study. The students were randomly selected from three schools located in a medium sized town in Greece. Perceived locus of causality was examined using Ryan and Connell’s (1989) motivational orientation scales, while intrinsic motivation was assessed by means of the Intrinsic Motivation Inventory (Ryan, 1982). Outcome expectancies for ten possible outcomes of school physical education were assessed by means of two different scales, namely outcome evaluation and outcome likelihood. Causal modelling analysis showed that intrinsic motivation was mainly influenced by perceived usefulness which in turned was influenced by outcome expectations. Moreover, outcome expectations also influenced perceived locus of causality. These results show that students’ outcome expectancies for their participation in school physical education is an important factor influencing their intrinsic motivation. 相似文献

This study aimed at investigating the relations between students' strategic behaviour during problem solving, task performance and domain-specific self-concept. A total of 167 first- and second-graders were individually examined in tasks involving cubes assembly and in academic self-concept in mathematics. Students' cognitive, metacognitive, and Motivational/Volitional Strategic Behaviours were video-recorded and rated by two independent observers. Structural equation modelling showed that the cognitive and Metacognitive Strategic Behaviours were explained by a cognitive self-regulation factor which correlated with the Motivational/Volitional Strategic Behaviour factor. The importance of the cognitive self-regulation factor for task performance and the association of domain-specific self-concept with Motivational/Volitional Strategic Behaviour were shown. 相似文献

Research has shown that differences in the prior knowledge of the participants and in the learning indexes adopted can explain why some studies show positive learning effects of analogy enriched text while others do not. In the present studies, these two factors were combined into one through the construction of a learning index that measured incremental positive changes in the participants' prior knowledge after reading an analogy enriched or no analogy text. A second learning index was also used to evaluate whether the participants created well-formed conceptual models after reading the science text. These learning indexes were used in two studies in which the effects of analogy enriched versus no analogy text were compared on the learning of the scientific explanations of the day/night cycle and of the seasons. The participants were 3rd and 5th graders in the first study and 6th graders and college students in the other. Although only few of the participants learned the correct scientific explanation, those who read the analogy enriched text produced more incremental positive changes in their pretest explanations at posttest and delayed test and created more well-formed conceptual models close to the scientific one than those who read the no analogy text. They also recalled more information and created fewer invalid inferences in their recalls. The results indicate that analogies can be used without reservation to facilitate the learning of science and have broader implications about how to evaluate the learning of science in general. 相似文献

This study examines antecedents and trajectories of advanced manufacturing technology (AMT) adoption in three categories: stand-alone, intermediate, and integrated technologies. Antecedents of adoption include prior investments in AMT, developments in firms’ manufacturing capabilities, technology strategy, absorptive capacity, and environmental pressures. Based on a sample of 87 Greek manufacturing SMEs, we find that AMT adoption follows an incremental, piecemeal progression from the least complicated through intermediate to integrated technologies. It is found that an increase in the firms’ quality and flexibility capabilities induces them to adopt further AMT, whereas advances in low-cost, innovation, and delivery capabilities appear negatively related to further AMT adoption. Absorptive capacity, technology strategy and environmental pressures play a central role in decisions for additional investments in AMT. In the context of a catching-up economy, these results support the notion of a ‘stepwise’ technology accumulation process as well as ‘satisficing’ technological change. 相似文献

The 3-step approach has been recently advocated over the simultaneous 1-step approach to model a distal outcome predicted by a latent categorical variable. We generalize the 3-step approach to situations where the distal outcome is predicted by multiple and possibly associated latent categorical variables. Although the simultaneous 1-step approach has been criticized, simulation studies have found that the performance of the two approaches is similar in most situations (Bakk & Vermunt, 2016). This is consistent with our findings for a 2-LV extension when all model assumptions are satisfied. Results also indicate that under various degrees of violation of the normality and conditional independence assumption for the distal outcome and indicators, both approaches are subject to bias but the 3-step approach is less sensitive. The differences in estimates using the two approaches are illustrated in an analysis of the effects of various childhood socioeconomic circumstances on body mass index at age 50. 相似文献

The purpose of this study was to examine the relationships between teachers' reports on self-regulatory strategy use in mathematics instruction and individual motivational and affective factors. Two hundred and ninety-two Greek primary school teachers responded to two questionnaires assessing (a) the strategies they use themselves to plan, monitor and evaluate mathematics instruction and (b) the strategies they use to activate and enhance students' self-regulated learning in mathematics. Path analysis showed that teachers' self-regulation strategies both for their own teaching and for enhancing students' self-regulation in mathematics were predicted by their self-efficacy beliefs in teaching mathematics, the value they attribute to mathematics and their emotional commitment to their profession. Teachers' enjoyment of mathematics teaching did not directly predict their reported use of self-regulatory instructional strategies. The implications of the study are related to the development of teachers' training programmes in self-regulated instruction. 相似文献

The aim of the study was to investigate the relationships between elementary students’ reported use of self-regulatory strategies in mathematics and their motivational and affective determinants. Participants of the study were 344 fifth- and sixth-grade Greek students. Students were asked to complete self-reported measures regarding the strategies they use to self-regulate mathematics learning, their achievement goals in relation to mathematics, their self-efficacy concerning mathematics learning and achievement, the value they attribute to mathematics as a subject domain and their enjoyment of mathematics learning. Structural equation modelling confirmed a mediation model, that is, students’ mathematics self-efficacy, value beliefs about mathematics and enjoyment mediated the effects of achievement goals on reported strategy use. Results are discussed in terms of implications for elementary students’ self-regulated learning skills. 相似文献
