Effects of Conceptual Change Texts and Laboratory Experiments on Fourth Grade Students’ Understanding of Matter and Change Concepts

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.     

INVESTIGATING THE EFFECTIVENESS OF AN ANALOGY ACTIVITY IN IMPROVING STUDENTS’ CONCEPTUAL CHANGE FOR SOLUTION CHEMISTRY CONCEPTS

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.     

Preservice teachers' perceptions about using mobile phones and laptops in education as mobile learning tools

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.     

Inequality in social capital: social capital,social risk and drop-out in the Turkish education system

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.     

Parent Versus Child Reports of Parental Advertising Mediation: Exploring the Meaning of Agreement

In a survey among 360 parent-child dyads (children aged 8–12 years), parent and child reports of parental advertising mediation activities were examined. The first aim was to investigate how parent-child agreement in reporting mediation differed by family and child factors. Results showed that agreement was highest in communication-oriented families and between parents and girls. The second aim was to examine the role of agreement in predicting the mediation outcome (i.e., reduced materialism). Both measures predicted the mediation outcome, but its effectiveness was contingent on parent-child agreement. Mediation was most effective when parents and children both reported that parents often discussed advertising.     

SCIENTIFIC RESEARCH AND SUSTAINABLE HUMAN DEVELOPMENT IN THE REPUBLIC OF MOLDOVA

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.     

A model for Islamic education from Turkey: the Imam-Hatip schools

The aim of this article is to examine the Imam-Hatip schools and their basic features, the characteristic model of Islamic education in Turkey that was proposed as an alternative model for other Muslim countries during their madrasa reform movements in the aftermath of the September 11 events in the USA. In the continuation of the madrasa tradition during the Saljuki period under state supervision, along with the modernisation efforts in education since the late Ottoman period, these schools have been revitalised and adapted to the contemporary conditions of educational institutions. At the foundation of these schools, there lay a notion of reconciliation between the ‘traditional’ and ‘modern’. Throughout the years of the Turkish Republic, these schools have constantly become a controversial issue in terms of their number, structure, and student and alumni profiles. Especially after the opening process of the Turkish people and Turkish foreign policies to the world, the issue has become an international one since the 1980s. After the events of 11 September 2001, these schools were offered as an alternative model for madrasas in Muslim countries and therefore drew international attention to themselves.
