Understanding students’ learning processes and education-related phenomena by extracting knowledge from educational data sets represents a continuous interest in the educational data mining domain. Due to an accelerated expansion of online learning and digitalisation in education, there is a growing interest in understanding the impact of online learning on the academic performance of students. In this study, we comparatively investigate traditional and synchronous online learning methods to assess students’ performance through the use of deep autoencoders. Experiments performed on real data sets collected in both online and traditional learning environments showed that autoencoders are able to detect hidden patterns in academic data sets unsupervised; these patterns are valuable for the prediction of students’ performance. The obtained results emphasized that, for the considered case studies, traditional evaluations are a little more accurate than online evaluations. Still, after applying a one-tailed paired Wilcoxon signed-rank test, no statistically significant difference between the traditional and online evaluations was observed.

Akibat munculnya pandemi Covid-19, banyak sekolah di Indonesia yang menerapkan sekolah dari rumah di mana guru dan siswa harus belajar dari rumah, termasuk di sekolah dasar. Berdasarkan fakta tersebut, tak pelak, guru dan siswa ditantang untuk melakukan pembelajaran daring sinkron. Oleh karena itu, tujuan dari penelitian ini adalah untuk menganalisis pengaruh pembelajaran online sinkron terhadap prestasi belajar matematika siswa. Penelitian ini menggunakan metode triangulasi yang dapat membantu dalam mengkonfirmasikan kumpulan temuan berdasarkan hipotesis. Untuk memenuhi tujuan tersebut, 16 siswa kelas 4 SD di Jakarta direkrut sebagai peserta penelitian. Data dikumpulkan dari nilai akhir mata pelajaran matematika siswa di semester-1 (tatap muka) dan semester-2 (pembelajaran online sinkron), serta hasil observasi peserta selama 3 bulan pada semester-2 (pembelajaran online sinkron). Berdasarkan perhitungan analisis menggunakan aplikasi SPSS, Paired Sample T-Test menunjukkan nilai sig. (2-tailed) sebesar 0,014. Hasil 0,014 berada di bawah 0,05 yang berarti pembelajaran online sinkron telah menyebabkan penurunan yang signifikan pada hasil belajar matematika siswa dibandingkan dengan pembelajaran tatap muka. Faktor yang bisa mempengaruhi pencapaian siswa adalah kesiapan siswa dalam menggunakan teknologi dan media, manajemen waktu, kondisi fisik dan mental siswa terhadap pembelajaran online dan fokus diskusi.

Data supporting the use of etoposide-based therapy in hemophagocytic lymphohistiocytosis (HLH) arise largely from pediatric studies. There is a lack of comparable data among adult patients with secondary HLH. We conducted a retrospective study to assess the impact of etoposide-based therapy on outcomes in adult secondary HLH. The primary outcome was overall survival. The log-rank test was used to compare Kaplan-Meier distributions of time-to-event outcomes. Multivariable Cox proportional hazards modeling was used to estimate adjusted hazard ratios (HRs) with 95% confidence intervals (CIs). Ninety adults with secondary HLH seen between January 1, 2009, and January 6, 2020, were included. Forty-two patients (47%) received etoposide-based therapy, while 48 (53%) received treatment only for their inciting proinflammatory condition. Thirty-three patients in the etoposide group (72%) and 32 in the no-etoposide group (67%) died during follow-up. Median survival in the etoposide and no-etoposide groups was 1.04 and 1.39 months, respectively. There was no significant difference in survival between the etoposide and no-etoposide groups (log-rank <i>p</i> = 0.4146). On multivariable analysis, there was no association between treatment with etoposide and survival (HR for death with etoposide = 1.067, 95% CI: 0.633–1.799, <i>p</i> = 0.8084). Use of etoposide-based therapy was not associated with improvement in outcomes in this large cohort of adult secondary HLH patients.

Purpose Black British minority ethnics (BME) students are nationally underachieving in comparison to their Ethnic Chinese and White peers, showing typically a 16 per cent graduate attainment gap in the UK. Previous research has suggested that the attainment gap could be explained by BME student disengagement, as the students typically commute from family home to University, and they work part time. However, peer-assisted learning (PAL) has been shown to have a positive impact on addressing and resolving student alienation and disengagement. However, a question still remains regarding whether student perceptions hold up to statistical analysis when scrutinised in comparison to similar cohorts without PAL interventions. The paper aims to discuss these issues. Design/methodology/approach This paper presents the results of a statistical study for two cohorts of students on engineering courses with a disproportionately high representation of BME students. The research method involved a statistical analysis of student records for the two cohorts to ascertain any effect of correlation between: PAL; student ethnicity; and student parental employment on student academic performance and placement attainment. Findings The results indicate that PAL has no significant impact on the academic performance; however, PAL has a positive impact on the placement/internship attainment for BME students and students from parental households with parents in non-managerial/professional employment. Research limitations/implications The research limitations are that the cohorts are small, but more equal diverse mix of different social categories than any other courses. However, as the cohorts are less than 30 students, comparing social categories the data sets are small to have absolute confidence in the statistical results of academic performance. Even the t-test has its limitations as the subjects are human, and there are multiple personal factors that can impact an individual academic performance; therefore, the data sets are heterostatic. Practical implications The results highlight that there is need for pedagogy interventions to support: ideally all BME students from all social categery to secure placements; BME students who are unable to go on placement to gain supplementary learning that has the same impact on their personal development and learning as placement/internship experience; and White students from managerial/professional family households to engage more in their studies. Social implications Not addressing and providing appropriate pedagogy interventions, in the wider context not addressing/resolving the BME academic and placement attainment gap, a set of students are being disadvantaged to their peers through no fault of their own, and compounding their academic attainment. As academics we have a duty to provide every opportunity to develop our student attainment, and as student entry is generally homogeneous, all students should attain it. Originality/value Previous research evaluation of PAL programmes has focused on quantitative students surveys and qualitative semi-structured research interviews with students on their student engagement and learning experience. On the other hand, this paper evaluates the intervention through conducting a quantitative statistical analysis of the student records to evaluate the impact of PAL on a cohort’s performance on different social categories (classifications) and compares the results to a cohort of another group with a similar student profile, but without PAL intervention implementation.

Participation in synchronous online learning is an increasing need for students’ learning outcomes. Teachers generally cannot be sure about the fact that students who are seen in the participation lists are really following the online tasks. Recent studies have shown that gamification can be an effective way to support learners’ participation in the tasks. This study intended to suggest sample scenarios in line with using gamification elements in online learning environments. Two basic scenarios were developed considering the properties of online learners’ characteristics and gamification elements. First scenario giving learning responsibilities to the learners includes a puzzle activity. Second scenario presents a block-building activity including the leaderboards. The suggested model includes some new ways of using awards, reputation, badges, levels, and leader boards to provide an attractive learning environment. It is hoped that suggested scenarios can provide learning opportunities via increasing participation in synchronous learning environments.

For the past decade, the Community of Inquiry (CoI) framework has been validated and applied to asynchronous online learning. This chapter proposes to explore its innovative application to synchronous online learning which has to date received little attention in the literature. This chapter reports on effective ways to engage graduate students attending virtual seminars in real time, based on the findings of a qualitative doctoral study that took place in five Francophone and Anglophone North American universities. The crucial role of the faculty member as the facilitator of a rich and ongoing dialogue in the classroom has yet to be identified with, and embraced by faculty, but students are generally satisfied with their virtual graduate seminars.
