This study examined the relations of preservice science teachers’ attitudes towards technology use, technology ownership, technology competencies, and experiences to their self-efficacy beliefs about technological pedagogical content knowledge (TPACK). The present study also investigated interrelations among preservice teachers’ attitudes towards technology use, technology ownership, technology competencies, and experiences. The participants of study were 665 elementary preservice science teachers (467 females, 198 males) from 7 colleges in Turkey. The proposed model based on educational technology literature was tested using structural equation modeling. The model testing results revealed that preservice teachers’ technology competencies and experiences mediated the relation of technology ownership to their TPACK self efficacy beliefs. The direct relation of their possession of technology to their TPACK self efficacy beliefs was insignificant while the indirect relation through their technology competencies and experiences was significant. The results also indicated there were significant direct effects of preservice teachers’ attitudes towards technology use, technology competencies, and experiences on their TPACK self efficacy beliefs. 相似文献

Humanoid robots equipped with social skills have come to be used increasingly in the field of education across various subfields such as science education, special education, and foreign language education. In order to enhance the use of humanoid robots in educational settings, and to comprehensively evaluate its impact on the transformation of the class, understanding students’ attitudes towards the use of robots for educational purposes plays a critical role. This paper outlines the implementation and validation procedures of an educational robot attitude scale (ERAS) developed to measure the attitudes of secondary school students towards the use of humanoid robots in educational settings. The sample of the study comprised of 232 secondary school students. The development and validation process consisted of exploratory factor analysis and convergent validity. The developed scale consists of 17 items and represents four factors of students’ attitude: engagement, enjoyment, anxiety and intention. These four factors accounted for 66% of the total variance of the scale. Internal consistency coefficient for the whole scale was found .90 according to the reliability analysis. The results of the study suggest that the scale is a valid, reliable, and efficient tool for measuring the dimensions of students’ attitudes towards humanoid robots in educational settings. 相似文献

The physics questions submitted to an ‘ask a scientist’ website were classified with respect to field of interest in physics,
type of requested information in the question (factual, explanatory, etc.), and motivation for asking the question (applicative
or non--applicative). In addition, differences in the number of females’ and males’ questions in these classifications were
determined. Analysis of 995 physics questions submitted to the website indicated that modern physics questions (30.7%) were
the most frequent while vibrations and wave motion questions (3.3%) were the least frequent. More than half of the questions
(57.8%) were submitted to request factual information. Motivation to ask a question was inferred from the question, and was
generally not related to direct and/or personal application. There were obvious differences in the number of questions asked
by females and males: 84.7% of questions were asked by males while 15.3% were asked by females. However, significant gender
differences were not observed in field of interest in physics, type of information requested in the question, and motivation
for asking the question. 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

This study examined teachers’ questions and children's responses during a play-based activity implemented in small groups within preschool classrooms. The first aim of this study was to describe teachers’ questions in terms of four levels of abstraction (i.e., a continuum of literal to inferential questions) and children's responses to these questions. The second aim was to examine the relations between teachers’ questions and children's responses using sequential analyses, to include children's level of abstraction and mean length of utterance (MLU). Participants were 39 teachers and up to six children from their preschool classroom. We found that teachers’ questions made up an average of 25% of their talk to children during play, and were relatively balanced between literal and inferential questions. Furthermore, significant sequential associations were found between the level of abstraction of teachers’ questions and the level of abstraction of children's responses (e.g., teachers’ inferential questions tended to elicit children's inferential responses). Finally, we found that teachers’ inferential questions were not related to children's MLU; that is, teachers’ more abstract questions did not elicit longer utterances from children. These findings suggest that play is a valuable context in which teachers may promote children's use of inferential language. 相似文献
