The authors developed and initially validated the Supervisee Disclosure in Supervision Scale (SDSS). Exploratory and confirmatory factor analyses with 2 independent samples revealed that the SDSS is a 17-item instrument with 2 subscales showing promising psychometric properties. The authors discuss the findings with implications for supervision training, practices, and research. 相似文献

The purpose of this study was to investigate whether conceptual change texts and laboratory experiments are effective in overcoming
misconceptions and whether the concepts were acquired permanently when these methods were utilized. In this study, we addressed
some topics from the “Matter and Change” unit in science and technology class of elementary 4th grade. Students from three
classes of an elementary school participated in the study (N = 104). Students’ misconceptions were determined by administering the “Matter Concept Test” before, immediately after and
13 weeks after the instructional period. The results of the study showed that both conceptual change texts and experiment
method were more successful than traditional instruction in overcoming the misconceptions and acquiring permanent knowledge.
However, there was not a significant difference between these two alternative approaches in terms of reducing the misconceptions. 相似文献

INVESTIGATING THE EFFECTIVENESS OF AN ANALOGY ACTIVITY IN IMPROVING STUDENTS’ CONCEPTUAL CHANGE FOR SOLUTION CHEMISTRY CONCEPTS 总被引:1,自引:0,他引:1

This paper reports on an investigation on the use of an analogy activity and seeks to provide evidence of whether the activity
enables students to change alternative conceptions towards views more in accord with scientific views for aspects of solution
chemistry. We were also interested in how robust any change was and whether these changes in conceptual thinking became embedded
in the students’ long-term memory. The study has its theoretical basis in an interpretive paradigm, and used multiple methods
to probe the issues in depth. Data collection consisted of two concept test items, one-on-one interviews, and student self-assessment.
The sample consisted of 44 Grade 9 students selected from two intact classes (22 each), from Trabzon, Turkey. The interviews
were conducted with six students selected because of evidence as to their significant conceptual change in solution chemistry.
The research findings revealed statistically significant differences in pre-test and post-test scores, and pre-test and delayed
post-test scores (p<0.05), but no differences between post-test and delayed test scores (p>0.05). This suggests that the analogy activity is helpful in enhancing students’ conceptual understanding of solution chemistry,
and that these changes may be stored in the students’ long-term memory. 相似文献

The purpose of this research was to investigate preservice teachers' perceptions about using m‐phones and laptops in education as mobile learning tools. A total of 1087 preservice teachers participated in the study. The results indicated that preservice teachers perceived laptops potentially stronger than m‐phones as m‐learning tools. In terms of limitations the situation was balanced for laptops and m‐phones. Generally, the attitudes towards using laptops in education were not exceedingly positive but significantly more positive than m‐phones. It was also found that such variables as program/department, grade, gender and possessing a laptop are neutral in causing a practically significant difference in preservice teachers' views. The results imply an urgent need to grow awareness among participating student teachers towards the concept of m‐learning, especially m‐learning through m‐phones. 相似文献

This article examines the effects of social capital on the likelihood of dropping out from the compulsory education system (Grades One through Eight) in Turkey. It focuses on the question of whether school-related social capital can provide the means to stay in school in the presence of risk factors such as socioeconomic status, race, or gender that cannot be easily modified. Despite major progress in enrollment rates due to policies enacted in recent years, the overall drop-out rate in compulsory education is close to 15% in Turkey. Data collected from 764 student–mother pairs show that drop-outs are exposed to higher number of social risk factors. We further illustrate that school-related social capital, as measured by quality of in-school teacher–student interactions as well as parental involvement in school, significantly and positively contributes to adolescents’ likelihood of staying in school even in the presence of severe social inequalities. 相似文献

Independence and transition to a market economy have led to economic decline in the Republic of Moldova. Scientific research directed at sustainable human development is the key to economic renewal. As Moldova must import most of its energy, a major task is to reduce energy consumption through improved energy efficiency. Since the basic source of national wealth is agriculture, the development of derivatives of agriculture, such as the bio‐chemical industries, the pharmaceutical industry, the perfume industry, and the veterinary sciences should be stressed as well as components of information technology in which Moldova has a lead. As the premier research organization of Moldova is its Academy of Sciences founded in 1946, it should channel its best efforts into the economic development of the country through science. 相似文献
