PENINGKATAN PRESTASI BELAJAR FISIKA MELALUI METODE EKSPERIMEN SISWA KELAS XI MIA 1 SMAN 3 BENGKALIS

Classroom action research on using experiment methods to inprove students physics learning achievement. Experimental learning method is a way of teaching and learning that involves students experiencing and proving themselves into process of the experimental results. With experiments, it is hoped that students can really understand the physics concepts being studied. The problem to be solved is the low achievement in learning physics as shown by the physics learning outcomes of class XI MIA 1 students at SMA Negeri 3 Bengkalis. This study consisted of 2 cycles, in each cycle consisting of 4 stages, namely Planning, Implementation, Observation and Reflection. This study involved 23 students of class X1 MIA 1 SMA Negeri 3 Bengkalis consisting of 10 male students and 13 female students. Before the implementing of the experimental method, the percentage of learning completeness was 17.39%, then after the first cycle of learning using the experimental method there was an increase in the percentage of learning completeness to 43.48%. In the second cycle succeeded in achieving the percentage of learning completeness 73.91%. The results showed that there was an increase in student achievement along with the implementation of the experimental method. Thus, the application of the experimental method can improve the physics learning achievement of class XI MIA 1 SMA Negeri 3 Bengkalis.

The Effectiveness of the Application of Rock Painting Activities in Developing the Creativity of Children aged 5-6 Years in Kindergarten

The study was set back by the low the creativity of children age 5-6 years in the Adzkia Air Bangis. one of the key factors this is suspected because it is not suitable or the media used by the teacher is not interestig. This study aims to determine the effectiveness of the application of rock painting activities in developing the creativity of children aged 5-6 years in kindergarten Adzkia Air Bangis. the type of research is quantitative usng pseudo-experiment methods (quasi experiment) with pre-test design and post-test. The research population is 55 people. While the sampel 10 children. Sampling retrieval techniques are used sampling samples. The data uses t-test samples samples. As a result of the coclusion to the data collaction and management, 1) before being given an treatment (pre-test) the development of children’s creativity can be categorized as starting to develop but has not developed as expected. This is based on the result of research by researchers at Adzkia Air Bangis Kindergarten 2) after being given treatment (post-test) the development of chidren’s creativity can be categorized as developing according to expectations. 3) there is significant difference between the result of the pre-test and post-test after doing the paired sampe t-test sig 0,000 < 0,05. Advice for teachers helping teachers by using experimental learning methods to develop the creativity of children aged 5-6 years trough rock painting activities.

ВИХОВНИЙ ПОТЕНЦІАЛ УРОКІВ ЧИТАННЯ ДЛЯ ФОРМУВАННЯ ТОЛЕРАНТНОСТІ МОЛОДШИХ ШКОЛЯРІВ

The article emphasizes that the world around us sets its own requirements for the ability of a junior student to adapt to it, to his tolerant willingness to build constructive relationships with others. In reading lessons, which aim, among other things, to form the values of primary school students, they learn to choose an individual way of self-presentation, behavior and communication. The task of the teacher is to teach to observe life, to notice human kindness, sacrifice, courage, as well as heartlessness, cruelty, indifference. Hence the signs of a tolerant personality, such as patience, indulgence, tolerance for differences, kindness, the ability to listen to others, not to judge others, to take their position, the ability to empathize, humanism. The updated content of literary material, which comprehensively covers the sphere of interests of junior schoolchildren, its emotionality, novelty, decoration, interesting forms and methods of working with texts of works and children's books with preference to problematic, creative tasks should convince students that fiction is a special kind of art, and reading – a special, unique means of satisfying cognitive interests, knowledge of the world and self-knowledge, which can not be replaced by any other means of mass culture. In the process of experimental learning, we tried to design and implement such types of educational activities of students, which contributed to the formation of tolerance in them as the most important value of the individual. After analyzing some aspects of updating the content and methodology of reading lessons in primary school in the context of implementing the ideas of tolerant education, we note that the new textbooks and manuals for extracurricular reading contain many texts with the potential for educating this quality of personality. actions of characters; to feel the state of another person, to make a moral choice. Key words: formation of tolerance in junior schoolchildren, reading lessons, educational potential of reading lessons, formation of personality of junior schoolchildren.

The Abilities Related to Organizing Experiential Learning Activities for Vietnamese Undergraduate Teacher Training Students

Experimental learning, often known as hands-on learning, is a kind of active learning that takes place in the classroom. Many institutions globally have utilized it to build educational programmes, and it is widely regarded as a best practice in the field. Specifically, the purpose of this research was to examine the feasibility and efficacy of improving students' capacity to design experiential learning events in order to better prepare them for the job. Participants in this research included a total of 470 participants, including 420 students, 50 lecturers and representatives from the Ho Chi Minh City University of Education's Youth Union and Students Association. They responded to seven questions regarding their ability to organize experiential learning activities for undergraduate students, as part of a broader questionnaire they completed. However, while both lecturers and students recognized the critical importance of abilities related to the organization of experiential learning activities, the findings of the study revealed that these abilities were not well designed or efficiently purposed for undergraduate students in the context of experiential learning. In order for students to improve their professional skills and gain more useful experience in the area of event planning, they should be encouraged and taught accordingly.

Sequential Procurement with Contractual and Experimental Learning

We study the design of sequential procurement strategies that integrate stochastic and strategic information. We consider a buyer who repeatedly demands a certain good and is unable to commit to long-term contracts. In each time period, the buyer makes a price offer to a seller who has private, persistent information regarding his or her cost and quality of provision. If the offer is accepted, the seller provides the good with a stochastic quality that is not contractible. Therefore, the buyer can learn from the (strategic) acceptance decisions taken by the seller and from evaluations of the (stochastic) quality delivered whenever a purchase occurs. Hence, the buyer not only faces a tradeoff between exploration and exploitation but also needs to decide how to explore: by facilitating quality experimentation or by strategically separating seller types. We characterize the perfect Bayesian equilibria of this sequential interaction and show that the buyer’s equilibrium strategy consists of a dynamic sequence of thresholds on his or her belief on the seller’s type. When only one seller type is more efficient than the buyer’s outside option, the buyer uses one form of information: either strategic or stochastic. If both seller types are more efficient, then the buyer uses both forms of information; at the early stages of the interaction, the buyer offers high prices that incentivize trade and quality experimentation, and after gathering enough information, the buyer may advance to offering low prices that partially separate seller types. We identify the effect strategic sellers have on the buyer’s optimal strategy relative to more traditional learning dynamics and establish that, paradoxically, when sellers are strategic, the ability to observe delivered quality is not always beneficial for the buyer.
