EFFECTS OF A MULTIFOCUSED PREVENTION PROGRAM ON PRESCHOOL CHILDREN'S COMPETENCIES AND BEHAVIOR PROBLEMS

This study was designed to assess the effectiveness of a multifocused (child‐, teacher‐ and parent‐focused) prevention program for Romanian preschoolers, targeting social–emotional competence development, as well as reduction of behavior problems. Fourteen classrooms were randomly assigned to the intervention and control conditions. Subsequent hierarchical linear analyses indicated that intervention‐group children performed better on experimental tasks measuring emotion knowledge and social problem‐solving strategies, and received higher assessments by their teachers and parents on measures of social–emotional competencies and externalizing problems. These results indicate that a prevention program combining intervention strategies for both high‐ and low‐risk children is effective across a wide range of adaptive and maladaptive behaviors. Moreover, a short four‐session parent group training employed to attract parent participation elicited an acceptable overall attendance rate (54%), indicating the sustainability of parent intervention in the context of community‐based interventions.     

The MacWilliams identity for m-spotty Rosenbloom–Tsfasman weight enumerator

The communication systems and disk or tape memory can sometimes cause clusters of errors, namely burst errors. There have been many designs in order to detect and even correct such errors. Recently, a new class of codes called m-spotty byte error correcting codes has found applications in high speed memory systems that employ random access memory chips wide Input/Output data, especially at 8, 16, or 32 bits. The MacWilliams identity provides the relationship between the weight distribution of a code and that of its dual code. Also, an interesting new metric called Rosenbloom–Tsfasman metric has been studied as an alternative metric for linear codes recently. In this paper, we combine these two interesting topics and introduce the m-spotty Rosenbloom–Tsfasman weights and the m-spotty Rosenbloom–Tsfasman weight enumerator of a binary code. Moreover, we prove a MacWilliams identity for the m-spotty Rosenbloom–Tsfasman weight enumerators.     

Preschoolers’ and first graders’ reasons for liking or avoiding school

ABSTRACT

This qualitative study examined 287 Turkish children's school experiences and sought to connect such experiences to their overall feelings about school. A semi-structured interview protocol derived from Ladd, Kochenderfer, and Coleman’s [1996. “Friendship Quality as a Predictor of Children’s Early School Adjustment.” Child Development 67 (3): 1103–1118] School Liking and Avoidance Questionnaire was used to collect data from the participants, who comprised 141 preschoolers and 146 first graders. Most members of both groups stated that school was fun, that they were happy when they were there, and that they felt happy about going to school in the morning. Most preschoolers and first graders also said that school did not make them feel like crying, and that they did not wish they could stay home from school or go somewhere else. However, slightly more than half the respondents stated that they felt happier when it was time to go home from school. Preschoolers tended to emphasise positive features of school such as toys, whereas first graders were more likely to talk about learning new things, and their in-school friendships.

CURRICULUM ASSESSMENT: CONSTRUCTIVIST PRIMARY MATHEMATICS CURRICULUM IN TURKEY

Many national and international studies put forward the idea that primary education in Turkey is questionable in many aspects. As a result, the Ministry of National Education changed primary curriculums in 2004 in Turkey. The curriculum for primary mathematics was redeveloped taking into consideration constructivist theory of education. The purpose of this study is to assess the qualities of the 2004 mathematics curriculum using a goal-oriented curriculum evaluation model in which the intrinsic value of the curriculum is examined in terms of its qualities and success depending on teachers’ perspectives, as they are one of the most important elements of the teaching–learning situation. The results show that the qualities of the 2004 mathematics curriculum match the criteria of a constructivist curriculum as set out in the literature. Also, the level of performance expected from the teachers’ perspective as those who instruct in the curriculum is very high. The results point to the fact that the 2004 mathematics curriculum may be considered as a positive change even if there is room for improvement in all aspects.

征婚广告在80年代以来占有重要位置,其历时性变迁反映出了广告媒介的历时性特点,广告主与媒介直接关 系导致分散的个体特征,广告资讯诉求方式的转变,以及广告受众的限制与广告效果低的原因——面对择偶,通过大众传 媒进行的大众传播逊于人际传播。     

Perceived social support,quality of life and satisfaction with life in elderly people

The aim of this study examines the relationship between quality of life, satisfaction with life and multidimensional perceived social support in people aged 65 years and older. The implementation part of the study was carried out with elderly people living in the city center of Burdur, Turkey. Data were collected in March 2018 from 517 participants and then assessed. The results of the analyses revealed that perceived social support explained 11.7% of the total variance in the satisfaction with life, 22.1% of the total variance in the quality of life. In addition to, the perceived social support and the quality of life explained 28.6% of the total variance in the satisfaction with life. And the quality of life was the most influential variable on the satisfaction with life. The findings of this study suggest that making improvements to the elderly people social support and quality of life will increase their satisfaction with life.     

Evaluation of the Effects of the Medium of Instruction on Science Learning of Hong Kong Secondary Students: Students’ Self-Concept in Science

A longitudinal study has been conducted to explore the impact of a new language policy for Hong Kong secondary schools on science learning. According to this policy, only schools that recruit the best 25% of students can teach science in English, the students' second language, while the other schools have to teach science in Chinese, the students' native language. The study involved a student cohort of 100 schools starting from S1 for three years. The outcome of science learning is conceptualized as consisting of students' achievement and self-concept in science. This paper reports the possible effects of English-medium instruction (EMI) and Chinese-medium instruction (CMI) on students' self-concept in science, as measured by students' responses to a questionnaire. Comparing with the CMI students, the EMI students showed higher self-concepts in Chinese, English and Mathematics, but a lower self-concept in science. This finding suggests that the EMI students might experience greater learning problems in science than in other subjects, probably because science learning involves abstract thinking and the mastery of scientific terminology which make a high demand on language proficiency. The EMI students showed a greater interest in learning science than the CMI students, indicating that they were more academically oriented. The EMI students, however, formed a lower perceived self-competence in science than their CMI peers, despite that they performed better in the science achievement test than many of the CMI students. This perception supports the view that using English for instruction may have negative effects on science learning. It is also consistent with the observation that the EMI students perceived science as more difficult to understand and learn than the CMI students.
