This research aims to evaluate the attitude instrument which will be used to asses the scientific attitudes in chemistry classes in High School in Parepare. The research will provide informations to identificate student scientific attitudes. Scientific attitudes in this paper consist of scientific attitude indicators. They are curiosity, honesty, objectifity, perseverence, conscientious, openness, being critical, and being responsible. The instrument evaluation is done by testing it to high school student to get its validity and realibility. The instrument has 8 aspects with 32 statements. The analysis result shows that Kaiser-Mayer-Olkin (KMO) indicator is 0.922. The Measure of Sampling Adequancy (MSA) in anti image correlation indicates that all of variables is greater than 0.5 which allows the data to be analysed further. The amount of variance and variable that can be explained by the factors forms 6 factors and cumulative variance 61,884%. The 32 items in the instrument, 26 items are fulfill the 6 factors. The Realibility of all items using Cronbach Alpha coefficient is 0.948. The analysis denotes that the instrument can be used to measure the student scientific attitudes in chemistry class with 26 items and 6 factors. The results of the analysis show that the instrument can be used to measure students’ scientific attitudes on chemistry learning with the number 26 and 6 factors formed.
In this study, Covid-19 modeling in Indonesia is carried out using a time series model. The time series model used is the time series model for discrete data. These models consist of Feedforward Neural Network (FFNN), Error, Trend, and Seasonal (ETS), Singular Spectrum Analysis (SSA), Fuzzy Time Series (FTS), Generalized Autoregression Moving Average (GARMA), and Bayesian Time Series. Based on the results of forecast accuracy calculation using MAPE (Mean Absolute Percentage Error) as model evaluation for confirmed data, the most accurate case models is the bayesian model of 0.04%, while all recovered cases yield MAPE 0.05%, except for FTS = 0.06%. For data for death cases SSA and Bayesian Models, the best with MAPE is 0.07%.
Penelitian ini bertujuan 1) untuk mengetahui proses pelaksanaan prakerin SMK Jurusan Teknik Tenaga Listrik pada DUDI, 2) untuk menghasilkan model pelaksanaan prakerin antara SMK Jurusan Teknik Tenaga Listrik dan DUDI, serta 3) untuk mengetahui kesiapan kerja siswa SMK setelah melaksanakan prakerin. Penelitian ini merupakan penelitian pengembangan yang difokuskan untuk mengembangkan model link and match melalui prakerin. Model pengembangan yang digunakan adalah modifikasi dari model Borg ang Gall (1983), ADDIE (1990), dan Dick and Carey (2001) yang dinamakan model HILDA. Model HILDA terdiri dari lima tahap yaitu: 1) How, 2) Innovation, 3) Learning, 4) Development, dan (Application). Hasil penelitian menunjukkan bahwa pengembangan model link and match yang dikembangkan setelah dilakukan validasi dinyatakan valid. Produk berupa buku panduan prakerin dinyatakan layak untuk digunakan karena seluruh aspek dalam pembelajaran berada pada kategori baik. Pengembangan model link and match melalui prakerin dinyatakan efektif karena telah memenuhi kriteria. Hasil penelitian memenuhi syarat kevalidan dan analisis data pengamatan pelaksanaan prakerin yang dilakukan siswa, SMK, dan DUDI menunjukkan bahwa pengembangan model HILDA layak untuk dikembangkan. Hasil analisis kesiapan kerja siswa berada kategori tinggi sehingga dapat dinyatakan bahwa siswa telah siap memasuki lapangan kerja. Berdasarkan hasil penelitian yang diperoleh maka disimpulkan bahwa pengembangan model link and match melalui prakerin yang dikembangkan telah memenuhi kategori kevalidan, kepraktisan, dan ketertarikan sehingga layak untuk dikembangkan.
This study aims to apply the pedagogical, andragogical and heutagogy approaches together in the lecture/learning process. This approach has novelty because there is no empirical evidence regarding the use of the three together in the classroom. This research was conducted in order to investigate the implementation of the three in the classroom using a descriptive quantitative approach by first checking the measurement model of the three. The sample in this study was 316 students voluntarily filling out electronic questionnaires. The collected data will be analyzed using a measurement model to investigate the validity and reliability of the model. Its constructs and indicators. The results of the research using the measurement model show that the three constructs are valid and reliable constructs. The indicators that make up the construct are also valid and reliable indicators. Descriptive statistics show that the lecture process in the midst of a pandemic is dominated by the andragogical approach. The heutagogical approach as the ideal approach used in higher education shows the lowest average response. Further research can be conducted by analyzing the relationship between the approaches as a continuum.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
