The Law

The purpose of this study was to develop teaching aids of blackbody radiation experiment and practicum devices based on modified free inquiry which are valid and reliable. This teaching aids was designed to demonstrate the relationship between the intensity of radiation and the absolute temperature of a blackbody (the law of Stefan-Boltzmann). The principle of this experiments is the amount of current will flow from the voltage source and enter to the black box. The black box will absorb and emit radiation. There is a nichrome wire inside the black box that will be light up, heat and emit radiation when electrically flowed. The emitted heat will be measured by temperature sensors using thermocouple located outside the black box. Based on experts and practitioner evaluation, the developed teaching aids of blackbody radiation experiment and practicum devices based on modified free inquiry were found to be valid, and reliable. The results of the experiment showed that the intensity of blackbody radiation was directly proportional to its temperature. This result is consistent with the law of Stefan-Boltzmann. Furthermore, the average of students’ perception of the developed teaching aids and practicum devices of blackbody radiation are 74.92% (good) and 80.17% (very good) respectively. This indicates that the teaching aids and practicum devices that have been developed can be used to demonstrate and prove the modern physics concepts related to blackbody radiation.Keywords: Teaching Aids, Stefan-Boltzmann’s law, Blackbody RadiationPenelitian ini bertujuan untuk mengembangan alat peraga eksperimen radiasi benda hitam dan perangkat praktikum fisika berbasis modified free inquiry yang valid dan reliabel. Alat peraga tersebut dirancang untuk mendemonstrasikan hubungan antara intensitas radiasi benda hitam dengan suhu mutlak yang dipancarkannya (Hukum Stefan-Boltzmann). Prinsip kerja dari alat peraga tersebut adalah arus akan mengalir dari sumber tegangan dan masuk ke dalam kotak lubang hitam. Kotak ini berfungsi untuk menyerap dan memancarkan radiasi. Di dalam kotak terdapat kawat nicrom yang akan menyala  dan memancarkan radiasi ketika dialiri arus listrik. Panas yang dipancarkan akan diukur oleh termokopel radiasi yang berada di luar kotak. Berdasarkan penilaian validator, alat peraga eksperimen radiasi benda hitam dan perangkat praktikum fisika berbasis modified free inquiry yang telah dikembangkan dinyatakan valid dan reliabel. Hasil uji coba menunjukkan bahwa intensitas radiasi yang dipancarkan oleh benda hitam berbanding lurus dengan temperaturnya yang sesuai dengan hukum Stefan-Boltzmann. Selanjutnya, rata-rata persepsi praktikan terhadap alat peraga eksperimen radiasi benda hitam dan perangkat praktikum yang telah dikembangkan secara berturut-turut adalah 74,92% (baik) dan 80,17% (sangat baik). Hal ini mengindikasikan bahwa alat peraga dan perangkat praktikum yang telah dikembangkan dapat digunakan untuk mendemonstrasikan dan membuktikan konsep-konsep fisika modern yang berhubungan dengan radiasi benda hitam.Kata kunci: Alat Peraga, Hukum Stefan-Boltzmann, Radiasi Benda Hitam

Learning about motion material such as straight-motion changes irregularly requires learning aids to analyze more deeply about speed. The problem that often occurs in learning motion material is that this material is only conveyed in the form of theory, has not touched the psychomotor domain from theory to practice. The concept of initial velocity and final velocity on the Irregularly Changing Straight Motion concept will be challenging to understand when dealing with applicable problems. Therefore we need learning aids to understand more integrally between theory and practice in analyzing speed by using a speed sensor (speed sensor). The speed sensor is used as an analysis of the real rate or travel time of Arduino-based objects. This study aims to develop physics teaching media using speed sensors as a realtime analysis based on Arduino. This research is a research & development (R&D) research using the Addie development model. The development stage of teaching aids consists of four stages, namely the analysis phase to analyze the needs of students and the components needed based on needs analysis, the design stage as a design stage based on needs analysis, the development stage is the stage of validating tools that have been designed by Ahlia Media and designing based on input by media experts..The results showed that the developed media produced expert validation values or the feasibility of the media with a category suitable for use in learning. The trial results show the learning media can increase the ability of problem solving by 2.2%.

Needs Analysis in the context of language-learning-teaching is an important process to design a certain course and syllabus. It helps course designers to set objectives, choose content, method of instruction, appropriate teaching aids, and classroom activities for different courses. This paper reports the perceptions of the researchers on the English language learning needs of the English undergraduate students of Shaheed Benazir Bhutto University Sheringal, Pakistan. The data is based on the researchers’ personal experience and first-hand observation of the population as the researchers have been teaching in the target context for about a decade. Furthermore, the researchers have always been in discussion with their students and colleagues about the target students’ English learning needs, preferred learning styles, motivation in learning English, interest, strengths/weaknesses, and attitude toward English learning in the target setting. Learners’ assignments, exam answer sheets, and presentations have also been used is a source of data collection. A needs analysis model proposed by Hutchinson and Waters (1987) has been applied in order to analyze the data. The results show that the students lack well grammatical sentences, have poor spellings, capitalization problems, limited vocabulary, unaware of collocations, poor/slow reading comprehension, and lack of effective presentation skills. Furthermore, most of the students have a lack of involvement in classroom activities and feel shy about speaking the English language. It was reported that the provision of authentic material, interesting activities, suitable audio-visual aids, relevant texts, language labs, and other logistic arrangements can better help them in learning the English language. The findings demonstrate that the students wished to have a learner-centered-course that helps them excel in their academic life and learning the English language.

Wax Models

Two early nineteenth century texts treating the production and use of wax models of fruit reveal the history of these objects in the context of courtly decoration. Both sources emphasise the models' decorative qualities and their suitability for display, properties which were not simply by-products of the realism that the use of wax allowed. Thus, such models were not regarded merely as visual aids for educational purposes. The artists who created them sought to entice collectors of art and natural history objects, as well as teachers and scientists. Wax models of fruits are known to have been collected and displayed as early as the seventeenth century, although only one such collection is extant. Before the early nineteenth century models of fruits made from wax or other materials (glass, marble, faience) were considered worthy of display because contemporaries attached great importance to mastery of the cultivation and grafting of fruit trees. This skill could only be demonstrated by actually showing the fruits themselves. Therefore, wax models made before the early nineteenth century may also be regarded as attempts to preserve natural products beyond the point of decay.
