Analysis of online learning based edmodo in pandemic era in atomic structure classes x at senior high school harapan 1 Medan

Education in Indonesia since middle-March 2020 has undergone significant changes. Online learning to answer questions is a solution to the virus problem that has spread to cut cases of the Covid-19 virus using online media. Edmodo is a learning application that the application can use in bold type learning, including atomic structure material. This study analyzes the Edmodo-based understanding used for learning media on atomic structure material and how students respond to the Edmodo application in chemistry learning, especially atomic structure material. The research method used is descriptive qualitative. The results showed that the effectiveness of learning was 69%, application sustainability during the pandemic was 76%, ease of access was 97%, ease of communication was 61%, the clear assessment was 84%, and understanding of the material Edmodo was 59%. Implementing chemistry learning consists of (1) choosing Edmodo as a bold learning medium in chemistry learning based on analyzing student needs with reasoning and mastery of applications; (2) planning the application as a student learning medium as described in the Semester Learning Plan; (3) implementation in Edmodo-based online learning is carried out well and smoothly based on semester learning plan; and (4) edmodo as an application can help carry out chemistry learning in atomic structure subjects to measure student learning outcomes. So it can be concluded that Edmodo is a practical application to use during the Pandemic of Covid-19.

Laboratory Investigations of Extrasensory Identification of Concealed 5-Character Codes by a Presumably Gifted Teenager

This report summarizes three “eyeless sight” experiments and reaffirms the authenticity of the phenomenon of clairvoyance (extrasensory perception). On 2014 and 2015, a total of 37 trials were conducted. Each trial involved a computer printing a 5-character permutation (e.g. 37K9J) in bold type on a piece of paper which was then folded to conceal the text. The “eyeless sight” practitioner was a girl who had previously been trained to develop her “eyeless sight” ability. The practitioner held the folded specimen between her thumb and forefinger. After adjusting to a specific state of consciousness (Second Consciousness State, SCS), the practitioner visualized a “ Third Eye Screen” (TES) in front of her forehead. The five-character string was then automatically perceived on the TES by the practitioner. After the perceived image stabilized, the permutation was reported to the researcher and transcribed. The whole experimental process was recorded on video cameras. The mean chance expectation for the correct hit rate of a five-character permutation is p≈10-70 and is vanishingly small. The importance of the SCS and the image generation process on the TES is discussed. Key words: Eyeless sight - Extrasensory perception (ESP) - Psychokinesis (PK) - Third Eye Screen (TES) - First Consciousness State (FCS) - Second Consciousness State (SCS) - recognition of characters with fingers (Clairvoyance)

Text usability test of French braid instructions

Usable texts should be extremely clear and functional. The present article focuses on instructions as a genre. Using French braid instructions as an example, the author presents how the form and layout of a text influence its usability. To this end an experiment was conducted on a sample of 32 individuals. The subjects received four versions of the same instructions — in the form of continuous text, in the form of continuous text with fragments in bold type, bullet point instructions and bullet point instructions with illustrations. The objective was to compare various forms of instructions (a form of text often used in everyday life, the clarity of which should consequently be as high as possible) in order to test their usability.

The expressive function of colloquialisms in professional discourse: The linguopragmatic aspect

In this study the expressive function of colloquialisms is examined through the lens of linguopragmatics using the material from professional discourse, which is marked by a strict structure of expressing ideas. The study identifies expressive means of influencing the recipient and traces general trends of using colloquialisms in the English-language mass media texts as well as transcripts of business talks held between some major companies. The paper elucidates the concept of linguopragmatics and defines the subject of studies within this discipline, as well as addresses notions of colloquialisms and their expressive function. We have found that colloquialisms are increasingly used in professional discourse. The study provides an overview of the concept of lexical-semantic field, as colloquialisms are mostly actualised at the lexical level. The authors investigate the lexical-semantic field “to invest money” comprised of colloquialisms from English-language mass media outlets, along with colloquialisms used in transcripts of large companies. The following expressive means of producing an influence on the recipient have been found in the texts: bold type, capitalisation of each word, italics, numerals, capitalisation of abbreviations (the graphic level); phrasal words, metaphors, allusions, positive particles, abbreviations, epithets, short forms of nouns (the lexical level); declarative sentences, interrogatory sentences, parcellation, antithesis, parallel structures (the syntactic level). The expressive function of colloquialisms is widely reflected in professional discourse. After comparing the use of colloquialisms in mass media texts and talks transcripts we found that the most frequent expressive means are declarative sentences at the syntactical level and metaphors at the lexical level.

Two urea-functionalized pcu metal–organic frameworks based on a pillared-layer strategy for gas adsorption and separation

Two pcu type Cu-MOFs based on urea-functionalized ligands have been synthesized by a pillared-layer strategy. Compound 1 shows good adsorption and separation behaviors of CO2, C2H6, and C3H8 over CH4, compound 2 exhibits a gate-opening behavior for N2 adsorption.
