In this study, the use of inquiry methods, learning cycles, a conceptual change model and analogy in creating alternative
science texts was discussed. An alternative text on the topic of acids and bases was created by integrating the methods and
models discussed in this paper. The alternative text and a sample of a traditional text taken from a textbook, which is still
used in Turkish high schools, were given to two groups, totaling 42 pre-service teachers—the alternative text was given to
an experimental group and the traditional text to a control group—in an experimental setting and their understandings of acids
and bases were compared. In addition, in the second step of the study, the pre-service teachers read both texts and indicated
their preferences in terms of interest, understandability and helpfullness. 相似文献

The article examines the opportunities and limitations of the coping behavior of children and teenagers on the Internet and the assistance that they receive from significant adults (parental mediation) in the context of the new developmental social situation, which is mediated by modern information and communication technologies, and in particular the Internet. The study was conducted on the basis of the EUKidsOnline II methodology in 11 regions in seven Russian federal districts (1,025 “parent–child” pairs). The study discovered that the most common risks include sexual and negative content, fraud and theft of personal information, as well as meetings with online acquaintances. The features of experiences and mechanisms used to cope with online risks depend on the predominant activity that a particular teenager pursues online, so that if children are focused on their studies online, they are less exposed to this risk. However, they are more deeply disturbed by such situations and remain so for longer periods of time, and they more frequently employ passive strategies to cope with them. So-called “content consumers” are at the greatest risk of encountering sexual content on the network. These users actively pursue various activities online, including search engines. They experience fewer negative emotions, and they often actively try to cope with the problem while rarely using offline support. There are few opportunities for parental mediation; these include blocking content and reducing the probability that children, and in particular the teenagers that are focused on their studies, will encounter risks. The strategy of explanation and encouragement is effective for teens who pursue various activities on the Internet, and is associated with a more realistic assessment of risk and young people's active use of coping and social support strategies. For the modern teenager, the Internet is a complex psychological “tool,” which he appropriates by probing its capabilities and opportunities for self-regulation, including coping with difficult life situations. 相似文献
The main purpose of the present research was to check the possibility of measuring the feeling of “intuitive acceptance”, experienced by a subject when he offers an intuitive solution to a problem. It was postulated that two dimensions have to be considered and combined: The level of confidence and the degree of obviousness. Almost all the questions asked referred to the notion of infinity. The subjects were pupils belonging to grades 8 and 9. Three main categories of problematic situations have been identified:
Problems which got high percentages of correct solutions and high levels of intuitive acceptance.
Problems which got two types of contradictory solutions, each of them being accepted with moderate intuitiveness.
Problems which got low frequencies of correct solutions and high frequencies of typical incorrect solutions, the second category presenting higher levels of intuitive acceptance than the first (counter-intuitive problematic situations).

Background: Numerous studies have been conducted to investigate the factors related to science achievement. In these studies, the classroom goal structure perceptions, engagement, and self-efficacy of the students have emerged as important factors to be examined in relation to students’ science achievement.
Purpose: This study examines the relationships between classroom goal structure perception variables (motivating tasks, autonomy support, and mastery evaluation), engagement (behavioral, emotional, cognitive, and agentic engagement), self-efficacy, and science achievement.
Sample: The study participants included 744 seventh-grade students from 9 public schools in two districts of Gaziantep in Turkey.
Design and methods: Data were collected through the administration of four instruments: Survey of Classroom Goals Structures, Engagement Questionnaire, Motivated Strategies for Learning Questionnaire, and Science Achievement Test. The obtained data were subjected to path analysis to test the proposed model.
Results: Students’ perceptions of classroom goal structures (i.e. motivating tasks, autonomy support, and mastery evaluation) were found to be significant predictors of their self-efficacy. Autonomy support was observed to be positively linked to all aspects of engagement, while motivating tasks were found to be related only to cognitive engagement. In addition, mastery evaluation was shown to be positively linked to engagement variables, except for cognitive engagement, and self-efficacy and engagement (i.e. behavioral, emotional, and cognitive engagement) were observed to be significant predictors of science achievement. Finally, results revealed reciprocal relations among engagement variables, except for agentic engagement.
Conclusions: Students who perceive mastery goal structures tend to show higher levels of engagement and self-efficacy in science classes. The study found that students who have high self-efficacy and who are behaviorally, emotionally, and cognitively engaged are more successful in science classes. Accordingly, it is recommended that science teachers utilize inquiry-based and hands-on science activities in science classes and focus on the personal improvement of the students. Furthermore, it is also recommended that they provide students with opportunities to make their own choices and decisions and to control their own actions in science classes. 相似文献
This study examined the extent to which different measures of speechreading performance correlated with particular cognitive abilities in a population of hearing-impaired people. Although the three speechreading tasks (isolated word identification, sentence comprehension, and text tracking) were highly intercorrelated, they tapped different cognitive skills. In this population, younger participants were better speechreaders, and, when age was taken into account, speech tracking correlated primarily with (written) lexical decision speed. In contrast, speechreading for sentence comprehension correlated most strongly with performance on a phonological processing task (written pseudohomophone detection) but also on a span measure that may have utilized visual, nonverbal memory for letters. We discuss the implications of this pattern. 相似文献
