Alternative views of the solar system among turkish students

This study examines middle-school students’ alternative frameworks of the earth’s shape, its relative size and its distance from the sun and the moon. The sample was selected in the province of Giresun in Turkey. Sixty-five 14-year-old students participated in the research. A structured interview consisting of open-ended questions was employed to reveal students’ ideas. The students’ verbal responses were scrutinized and categorized according to their level of understanding. The results showed that the students had many alternative frameworks with regard to astronomical concepts. Implications and recommendations were made for teachers, textbook authors, teaching materials developers and researchers for future research to remedy students’ alternative frameworks.     

Impacts of a university–school partnership on middle school students' fractional knowledge: A quasiexperimental study

In this quasiexperimental study, the authors investigated the effects of university within school partnership model, within which faculty members acted as teacher-researchers to improve fractional knowledge among middle school (Grades 5–8) students. Students in nine Grade 6 mathematics classes from two public middle schools in Turkey were assigned to two conditions: University within school model instruction and traditional instruction. Pre- and posttest data showed that the students exposed to instruction through the university within school partnership model significantly outperformed their traditional instruction peers on the fractions test. Results indicated that students made significant gains in fractional knowledge in the experimental classrooms and in different subgroup populations. It was suggested that a substantial amount of mathematical infusion through partnership could have a positive impact on middle school students' fractional knowledge. The educational implications of the study were also discussed.     

The effect of using augmented reality and sensing technology to teach magnetism in high school physics

ABSTRACT

The purpose of this study is to investigate the effect of MagAR, an instructional material for teaching magnetism using augmented reality and sensing technology, on students’ academic achievement and learning process, and to identify students’ views about augmented reality. An embedded mixed-method approach was employed in this study. The study’s results suggest that AR learning environments are effective in teaching physics, and facilitate learning by adding visual and textual components to the learning process. In learning activities integrated with AR, the students were observed to participate more, appeared more comfortable, were able to answer questions related to the subject more easily, had increased self-confidence and exhibited higher academic achievement levels in physics. The results suggest that AR should not be considered as an independent learning environment for the teaching of physics, but would be more effective as supplementary to the laboratory environment.     

A Study on Teaching Gases to Prospective Primary Science Teachers Through Problem-Based Learning

The aim of this study was to compare the achievement of prospective primary science teachers in a problem-based curriculum with those in a conventional primary science teacher preparation program with regard to success in learning about gases and developing positive attitudes towards chemistry. The subjects of the study were 101 first year undergraduate students, who were in two different classes and who were taught by the same lecturer. One of the classes was randomly selected as the intervention group in which problem-based learning (PBL) was used, and the other as the control in which conventional teaching methods were used. The data were obtained through use of the gases diagnostic test (GDT), the chemistry attitude scale (CAS), and scales specific to students’ evaluation of PBL such as the peer evaluation scale (PES), self evaluation scale (SES), tutor’s performance evaluation scale (TPES) and students’ evaluation of PBL scale (SEPBLS). Data were analysed using SPSS 10.0 (Statistical Package for Social Sciences). In order to find out the effect of the intervention (PBL) on students’ learning of gases, independent sample t-tests and ANCOVA (analysis of co-variance) were used. The results obtained from the study showed that there was a statistically significant difference between the experimental and control groups in terms of students’ GDT total mean scores and, their attitude towards chemistry, as well as PBL has a significant effect on the development of students’ skills such as self-directed learning, cooperative learning and critical thinking.     

巴基斯坦高等学校设置制度:缘起、程序及标准

在巴基斯坦现行高等教育行政管理机构及组织体系下,巴基斯坦高等学校设置制度的构建缘起、设置程序及标准具有一定的特色.研究发现,巴基斯坦高等学校设置程序围绕申请、审核、考察、赋权等四个环节进行,具备系统的设置标准,涵盖师资队伍建设、设备场地规范、经费使用、管理若干方面.巴基斯坦高等学校设置制度较为完备,符合本国国情,利益主体均衡,标准刚柔相济,但也存在重硬件、轻科研,未能为高等教育国际化纵深发展预留对接平台,以及“一刀切”色彩过重等问题.     

Optimizing search results for human learning goals

While past research has shown that learning outcomes can be influenced by the amount of effort students invest during the learning process, there has been little research into this question for scenarios where people use search engines to learn. In fact, learning-related tasks represent a significant fraction of the time users spend using Web search, so methods for evaluating and optimizing search engines to maximize learning are likely to have broad impact. Thus, we introduce and evaluate a retrieval algorithm designed to maximize educational utility for a vocabulary learning task, in which users learn a set of important keywords for a given topic by reading representative documents on diverse aspects of the topic. Using a crowdsourced pilot study, we compare the learning outcomes of users across four conditions corresponding to rankings that optimize for different levels of keyword density. We find that adding keyword density to the retrieval objective gave significant learning gains on some topics, with higher levels of keyword density generally corresponding to more time spent reading per word, and stronger learning gains per word read. We conclude that our approach to optimizing search ranking for educational utility leads to retrieved document sets that ultimately may result in more efficient learning of important concepts.

Field experiences in teacher education: the perceptions and qualities of written reflections

This study aimed to evaluate the Pre-service Teachers’ (PSTs’) field experience-related perceptions and the qualities of their written reflections. Two thousand four hundred journal entries written by 75 teacher candidates were analyzed to classify their qualities. In addition, semi-structured interviews were conducted with all of the subjects. The results showed that the largest proportion of the written entries was classified as technical. Only a small percentage of the subjects reached the highest level of reflection called as transformative. During the field experiences, the PSTs had mainly self, cooperating teachers, and student-related issues and perceptions. At the end of the field experiences, they recommended to start the practicum courses from the first year of the faculty and to increase the weekly hours of these courses. It is important to note that the PSTs need additional knowledge and practices about the reflection, reflective writing, and the qualities of reflection.     

Täuschungshandlungen im Sport

Experimental studies on the head fake in basketball showed that participant’s responses in a pass direction identification task were delayed for incongruent compared to congruent directions of the players gaze and pass (so-called head fake effect). In these studies on the head fake effect, static pictures were presented and responses on the pass direction were given with a simple key press. The present study examines whether an increase in the response complexity affects the head fake effect and whether it can also be transferred to the presentation of dynamic stimuli. In experiment 1, participants were presented with static pictures of a basketball player who passes a ball to the left or to the right. The player’s gaze direction was either oriented in the direction of the intended pass or in the opposite direction (i.?e., a head fake). The participants were asked to respond as quickly as possible to the pass direction and to ignore the gaze direction. Participants gave responses by pressing a key (simple response) or by executing a quasirealistic defense movement (complex response). Response complexity was blocked. In experiment 2, videos replaced the static stimuli. The responses were only given with the complex, full body movement. Results show that the head fake effect is independent of response complexity and that it can also be found when presenting dynamic stimuli.
