Abstract

Tujuan utama dari penelitian generalisasi validitas adalah untuk mengestimasi mean dan variansi validitas sesungguhnya dari suatu tes seleksi. Prinsip dasar dari model generalisasi validitas adalah pemartisian variansi, yaitu identifikasi dan pemilahan terhadap variansi dari validitas teramati yang bertanggung jawab terhadap error sistematik yang berhubungan dengan artifak statistik dan error dari random sampling. Model dasar untuk generalisasi validitas didasarkan pada suatu struktur persamaan untuk koefisien korelasi teramati antara prediktor X dan kriteria Y, dimana R adalah korelasi teramati, ρ’ adalah korelasi populasi yang dibatasi, dan e adalah peluang error yang berhubungan dengan sampling

Abstract

The Covid-19 pandemic is a major challenge for the education system. The face-to-face learning process shifted to online learning, including the school exams. In Aceh province, the school exams have changed from paper-based and computer-based. This research aims to analyze the difficulty index of an item bank based on cognitive aspects of Bloom’s Taxonomy. The study samples included 850 students. The data were the item bank of a final semester exam consisting of 200 multiple-choice items, answer keys, and students’ answer sheets. The empirical analysis of the item bank using classical test theory (CTT) found that 141 out of 200 items are valid based on content validity and computing data set using the Aiken’s V formula. Item tests have reliability of 0.983. The reliability is calculated using the Kuder-Richardson 21 formula. If the reliability coefficient is r11 ≥ 0.70, then the item is declared reliable. In addition, 62 out of 141 (43.97%) items from the item bank are classified with a moderate difficulty index, and 79 items (56.03%) are categorized with a high difficulty index. The cognitive aspects found in the items are remembering, understanding, applying, and analyzing. Students mostly found items with the cognitive aspects of remembering and understanding are difficult to solve.

Abstract

Student learning motivation is classified as less optimal due to several reasons, namely students tend to participate less during question and answer activities from their teacher and pay less attention to the teacher when delivering material in the learning process. The purpose of this research is to find out the application of the Scientific Inquiry Learning Model in increasing motivation and student learning outcomes on virus material. This study uses a pretest-posttest control group design experimental method. The parameters used are learning motivation and student learning outcomes collected through pretest and posttest. The data obtained were then tabulated and analyzed using the N-Gain formula to find out the improvement in learning outcomes. Next, a statistical analysis was carried out in the form of the Independent sample t-test and the Mann-Whitney test to determine differences in motivation scores and learning outcomes in the experimental and control class students. For learning motivation, the data obtained were also analyzed by the percentage of scores per indicator to determine its categorization. The results obtained for Independent sample t-test of the average learning motivation, obtained tcount = 5.07 ttable = 4.1. For categorization, the experimental class received an average of "very good", "good", and "good enough" categorizations. As for the learning outcomes obtained Mann-Whitney test results namely Zcount = 5.71 Ztable = 1.96 so it can be concluded that the Scientific Inquiry learning model can increase student motivation and can improve student learning outcomes on virus material.Motivasi belajar siswa tergolong kurang Optimal dikarenakan beberapa alasan yaitu siswa cenderung kurang berpartisipasi saat kegiatan tanya jawab dari gurunya serta kurang memperhatikan gurunya saat penyampaian materi dalam proses pembelajaran.

The type of research used was a quasі-experiment with a pre-test post-test control group design. The research subjects were students of class VII Darul Ihsan Islamic Junior High School Aceh Besar, which consisted of eight classes. The sample group was determined by purposive sampling technique so that two classes were obtained as the research sample, namely class VII-G as an experimental class and VII-H as a control class. The results showed that the implementation of the PjBL-STEM model could increase students’ science process skills. The average students’ science process skills in the control and experimental classes were 53 and 55 with sufficient categories. However, after implementing the Discovery Learning model in the control class and PjBL-STEM in the experimental class, the students' science process skills' average score increased to 76 with good categories and 86 with excellent categories. The PjBL-STEM model was also able to improve students’ learning outcomes. Based on the results of the t-test analysis with a significant score of 0.05, it showed that the post-test scores in both classes were obtained t-count (2.011) > t-table (1.666), so it was concluded that there was a significant difference between the two classes. N-gain testing showed an increase in students’ learning outcomes between the control and experimental classes with scores of 74 and 79. This study concluded that the PjBL-STEM model could improve science process skills and students’ learning outcomes.
