This study examined to what extent inquiry-based instruction supported with real-time graphing technology improves fourth grader??s ability to interpret graphs as representations of physical science concepts such as motion and temperature. This study also examined whether there is any difference between inquiry-based instruction supported with real-time graphing software and inquiry-based instruction supported with traditional laboratory equipment in terms of improving fourth graders?? ability to interpret motion and temperature graphs. Results of this study showed that there is a significant advantage in using real-time graphing technology to support fourth graders?? ability to interpret graphs.  相似文献   

Participation in online courses from the students’ perspective     

Betul Ozaydın Ozkara  Hasan Cakir 《Interactive Learning Environments》2018,26(7):924-942

The purpose of this study is to uncover factors that affect participation in online classes from the student’s perspective. Interest in the online environment has been increasing and renders the opinions of students participating in online courses more important since the opinions of students in this environment are closely related to interaction. It has been seen that lack of interaction creates a sense of loneliness, which causes students to drop their classes. For this reason, a qualitative study has been conducted about student experiences on the use of methods that increase interaction in an online environment and participation. Participants were given tasks based on collaboration, special attention was paid to make sure that the setting in which the participants found themselves was in accordance with the principles of the community of inquiry, computerized equipment was used to facilitate online interactions. 15 students worked based on collaboration and 15 students worked individually. Data was collected with interviews and reflection reports. Open, axial and selective coding was made by using the theorizing method. At the end of the study, it was determined that participation in online environment was affected in both groups by factors such as personal approaches, changing variables, mediated attributes.  相似文献   

Student Views of Teacher Actions in Science Classrooms Designed to Meet Current Reforms     

Stuart O. Yager  Hakan Akcay  Ozgur Kivilcan Dogan  Robert E. Yager 《Journal of Science Education and Technology》2013,22(6):974-983

Science/Technology/Society (STS) as a reform effort has been active in Iowa for three decades. A program called Iowa Chautauqua has evolved over the four decades to promote K-12 STS teaching in Iowa’s 300 school districts. This is a study of how teachers have become Teacher Leaders of the reforms and lead other teachers who enroll as new teachers and schools each New Year. All were involved with Action Research projects each year while also assisting graduate student teams who serve as research associates. In this study, students were asked to identify specific teacher actions that were designed to make student learning more successful. The study examines general student views of teacher actions as well as specific examples of how students interact with the teacher and how the teachers encourage greater student/student involvement. The results show success with STS and how it defines science and affective actions of teachers in classrooms. Student views of Teacher Leaders, new Chautauqua teachers, and Control Teachers with no STS or Chautauqua experiences provide ways of recognizing successes of current reform efforts.  相似文献   

Using Extraction Experiment as a Tool for Teaching Scientific Process Skills     

Hasan  ōzyildirim  Husnuye Durmaz 《美中教育评论》2013,(10):754-762

Laboratory work educates students about the ＂processes of science＂. But it is suggested that students＇ learning level is low because of limited application of science processes in their laboratory work. Extraction experiment was chosen as the topic since it allows students to apply many of their basic chemistry knowledge, and it can be readily to gain understanding of scientific proceses required for an investigation. This study has been carried out with 40 students who are in the first year of Science Teaching Division at Trakya University, Faculty of Education. These students were divided into two groups of the experimental group and the control group, each group containing 20 students. The students of the experimental group were given knowledge about basic scientific process skills, and a procedure in detail to follow was given. But the students of the control group was given a standard procedure. The students of both groups were asked about what and why they did while they were performing the laboratory investigation. We observed that the experimental group students used the basic process skills, understood the extraction experiment, and realized what and why they did from this activity better than the control group students. The control group students did not know why they did laboratory work and they tended to focus on completing the task rather than learning from it. We considered that the experience would be helpful for students to improve scientific process skills if the students successfully acquired procedural understanding. Students＂ scientific processskills will develop as long as they use the skills.  相似文献   

Construction of nationhood through education in Malaya: revisiting the Barnes and Fenn-Wu Reports     

Moses Samuel  Mahmud Hasan Khan 《Asia Pacific Journal of Education》2013,33(3):249-260

This article provides an analysis of two colonial reports, the Barnes and the Fenn-Wu Reports on education in the British colony of Malaya. The popular stance on the Barnes and the Fenn-Wu Reports is that one is an effect or reply to the other. We argue on the contrary that the two reports construct a common argument on nation-building which becomes apparent through a dialogic reading of the reports. We show how the two reports, written in the 1950s, reflect the anxiety of the colonial rulers in constructing a nation and the ethnic communities (the Malays and the Chinese) in pre-independent Malaya. These communities were constructed not without their inherent antagonism as well as their reciprocal vulnerabilities in a future political state. This act of articulation is predominantly a political act constructed through a complex web of interdiscursivity and intertextuality. The spectres of the Barnes and the Fenn-Wu Reports continue to surface in education and nation-building discourse in modern-day Malaysia.  相似文献   

Single-cell yolk-shell nanoencapsulation for long-term viability with size-dependent permeability and molecular recognition     

Li Wang  Yu Li  Xiao-Yu Yang  Bo-Bo Zhang  Nelle Ninane  Henk J Busscher  Zhi-Yi Hu  Cyrille Delneuville  Nan Jiang  Hao Xie  Gustaaf Van Tendeloo  Tawfique Hasan  Bao-Lian Su 《国家科学评论(英文版)》2021,8(4)

Like nanomaterials, bacteria have been unknowingly used for centuries. They hold significant economic potential for fuel and medicinal compound production. Their full exploitation, however, is impeded by low biological activity and stability in industrial reactors. Though cellular encapsulation addresses these limitations, cell survival is usually compromised due to shell-to-cell contacts and low permeability. Here, we report ordered packing of silica nanocolloids with organized, uniform and tunable nanoporosities for single cyanobacterium nanoencapsulation using protamine as an electrostatic template. A space between the capsule shell and the cell is created by controlled internalization of protamine, resulting in a highly ordered porous shell-void-cell structure formation. These unique yolk-shell nanostructures provide long-term cell viability with superior photosynthetic activities and resistance in harsh environments. In addition, engineering the colloidal packing allows tunable shell-pore diameter for size-dependent permeability and introduction of new functionalities for specific molecular recognition. Our strategy could significantly enhance the activity and stability of cyanobacteria for various nanobiotechnological applications.  相似文献   

Changes in organisation of instep kicking as a function of wearing compression and textured materials     

Hosni Hasan  Keith Davids  Jia Yi Chow  Graham Kerr 《European Journal of Sport Science》2017,17(3):294-302

This study investigated effects of wearing compression garments and textured insoles on modes of movement organisation emerging during performance of lower limb interceptive actions in association football. Participants were six skilled (age?=?15.67?±?0.74 years) and six less-skilled (age?=?15.17?±?1.1 years) football players. All participants performed 20 instep kicks with maximum velocity in four randomly organised insoles and socks conditions, (a) Smooth Socks with Smooth Insoles (SSSI); (b) Smooth Socks with Textured Insoles (SSTI); (c) Compression Socks with Smooth Insoles (CSSI); and (d), Compression Socks with Textured Insoles (CSTI). Results showed that, when wearing textured and compression materials (CSSI condition), less-skilled participants displayed significantly greater hip extension and flexion towards the ball contact phase, indicating larger ranges of motion in the kicking limb than in other conditions. Less-skilled participants also demonstrated greater variability in knee–ankle intralimb (angle–angle plots) coordination modes in the CSTI condition. Findings suggested that use of textured and compression materials increased attunement to somatosensory information from lower limb movement, to regulate performance of dynamic interceptive actions like kicking, especially in less-skilled individuals.  相似文献   

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

Mustafa Serkan Abdusselam  Hasan Karal 《Technology, Pedagogy and Education》2020,29(4):407-424

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.  相似文献   

The relationship between critical thinking skills and in‐class questioning behaviours of English language teaching students     

Hasan Şeker 《欧洲师范教育杂志》2008,31(4):389-402

It is important that trainee teachers in the faculties of education should develop their critical thinking skills so that they can meet the expectations and needs of their profession. This study aimed at investigating the relationship between critical thinking skills and in‐class questioning behaviours of English Language Teaching (ELT) students at the Faculty of Education at Mugla University. The authors attempted to find out answers to the following questions: ‘What kinds of questions do students in lower and higher critical thinking groups ask?’ and ‘Is there a difference between the questions of students with higher and lower critical thinking scores?’ Three data collection instruments were used: Ennis‐Weir Critical Thinking Essay Test; a reading passage; and a structured interview. The findings obtained suggest that the questions asked by the students of the higher critical thinking score group are not questions that clarify unclear points, but questions asked out of curiosity, to remove the uncertainties, and to lead people to think profoundly. Moreover, these students ask questions to find alternatives, to think the reverse and to head for new ideas. The students in the higher score group experienced thinking processes more intensively than the lower score group.  相似文献   

Differentiated Function of School in Socio-Culturally Disadvantaged Context: A Constructivist Grounded Theory Study from Turkey     

Zuhal Zeybekoglu Caliskan  Hasan Simsek  Yasar Kondakci 《The Urban Review》2017,49(3):400-419

This study analyses the functioning of a school as a social system in an atypical context with the purpose of generating propositions to tackle educational problems confronted by socially and economically disadvantaged groups attending these schools. Adopting the constructivist grounded theory, the analysis suggests that there is a kind of “vicious cycle” in the functioning of this atypical school, which adversely affects the school system. Breaking the vicious cycle involves five basic propositions: (1) making school a better place than students’ homes, (2) overcoming the enduring difficulties of working in an atypical school, (3) multiplying learning opportunities, (4) prompting parents to assume more responsibility, (5) locating leadership that makes a difference. These propositions clarify the significance of informal subsystems, school community and the wider environment along with their enabling and blocking effects on a disadvantaged school system. Parallel to other studies on disadvantaged schools, the study highlights the need to refine the orthodox view of the concept of formal education and school, as well as the role of school principal, teachers and parents affiliated with atypical schools.  相似文献
