    Interpreting Emojis: Millennials versus Non-Millennials

    The presence of emoticons--and now emojis--within written messages has increased since the advent of electronic communication. We conducted a quasi-experiment to learn whether a “smirk” emoji would be interpreted as indicating seductiveness by digital natives (Millennials) and non-digital natives (non-Millennials). We surveyed participants (N = 283) and asked them how they interpreted a message that contained the “smirk” emoji. Millennials were more likely than non-Millennials to infer seductiveness from this emoji. Our data suggest age-related differences in how various nonverbal cues are interpreted within electronic communication mediums

    The agricultural mechanics laboratory, that is a part of the agricultural science and technology instructional program in Texas public schools, has over the years become a key component of the instructional program. Four classes, as outlined in the Texas Essential Knowledge and Skills (TEKS) that focus on mechanical skills and include: Principles of Agricultural, Food, and Natural Resources, Agricultural Mechanics and Metal Technologies, Agricultural Facilities Design and Fabrication and Agricultural Power Systems. Most agricultural mechanics laboratories are used 4 to 5 class periods per day sometimes with more than one class at a time meeting in the facility,. The questions that arises is how safe are the labs and are they equipped to handle the classes and number of students in each class. This study was a preliminary study conducted as a part of the AGD 581 Methods of Teaching Agriculture in the Public School. Six graduate students visited 11 high schools and compiled data in the following areas: foot candles of light available, hours of use per day, and safety equipment, etc. The results will be shared with the participants

    Kesulitan Belajar Peserta Didik Dalam Membedakan Materi Bangun Datar Pada Pembelajaran Geometri Di Sekolah Dasar

    Penelitian ini berisi tentang hasil identifikasi dan analisis kesulitan-kesulitan yang dialami peserta didik dalam membedakan bangun datar dalam pembelajaran geometri di sekolah dasar. Metode yang digunakan yaitu metode campuran (mixed methods) yang melibatkan pendekatan kualitatif melalui observasi, wawancara, dan analisis dokumen, serta pendekatan kuantitatif menggunakan kuesioner dan tes diagnostik. Hasil dari  penelitian menunjukkan bahwa peserta didik mengalami kesulitan dibagian membedakan karakteristik unik masing-masing bangun datar, seperti jumlah sisi dan sudut, simetri, serta perbedaan dan persamaan di antara bangun-bangun tersebut. Faktor-faktor penyebab kesulitan ini termasuk keterbatasan pemahaman konsep, kurangnya keterampilan visualisasi, dan metode pengajaran yang kurang efektif. Penelitian ini menawarkan pendekatan-pendekatan pedagogis yang dapat diimplementasikan untuk mengatasi masalah tersebut dan meningkatkan kualitas pembelajaran geometri di sekolah dasar

    Electrochromic Radiator Coupon Level Testing and Full Scale Thermal Math Modeling for Use on Altair Lunar Lander

    In order to control system and component temperatures, many spacecraft thermal control systems use a radiator coupled with a pumped fluid loop to reject waste heat from the vehicle. Since heat loads and radiation environments can vary considerably according to mission phase, the thermal control system must be able to vary the heat rejection. The ability to "turn down" the heat rejected from the thermal control system is critically important when designing the system. Electrochromic technology as a radiator coating is being investigated to vary the amount of heat rejected by a radiator. Coupon level tests were performed to test the feasibility of this technology. Furthermore, thermal math models were developed to better understand the turndown ratios required by full scale radiator architectures to handle the various operation scenarios encountered during a mission profile for the Altair Lunar Lander. This paper summarizes results from coupon level tests as well as the thermal math models developed to investigate how electrochromics can be used to increase turn down ratios for a radiator. Data from the various design concepts of radiators and their architectures are outlined. Recommendations are made on which electrochromic radiator concept should be carried further for future thermal vacuum testing
