When failure fails to be productive

The current work builds on research demonstrating the effectiveness of Productive Failure (PF) for learning. While the effectiveness of PF has been demonstrated for STEM learning, it has not yet been investigated whether PF is also beneficial for learning in non-STEM domains. Given this need to test PF for learning in domains other than mathematics or science, and the assumption that features embodied in a PF design are domain-independent, we investigated the effect of PF on learning social science research methods. We conducted two quasi-experimental studies with 212 and 152 10th graders. Following the paradigm of typical PF studies, we implemented two conditions: PF, in which students try to solve a complex problem prior to instruction, and Direct Instruction (DI), in which students first receive instruction followed by problem solving. In PF, students usually learn from their failure. Failing to solve a complex problem is assumed to prepare students for deeper learning from subsequent instruction. In DI, students usually learn through practice. Practicing and applying a given problem-solving procedure is assumed to help students to learn from previous instruction. In contrast to several studies demonstrating beneficial effects of PF on learning mathematics and science, in the present two studies, PF students did not outperform DI students on learning social science research methods. Thus, the findings did not replicate the PF effect on learning in a non-STEM domain. The results are discussed in light of mechanisms assumed to underlie the benefits of PF

HIV pre-exposure prophylaxis during the SARS-CoV-2 pandemic

$\bf Aims:$ Since 2017, HIV pre-exposure prophylaxis (PrEP) care has been provided through an intersectoral collaboration at WIR (Walk-in-Ruhr, Center for Sexual Health and Medicine, Bochum, Germany). The aim of this study was to establish possible impact of COVID-restrictions on the sexual behavior of PrEP users in North Rhine-Westphalia. $\bf Methods:$ The current PrEP study collected data of individuals using PrEP, their sexual behavior and sexually transmitted infections (STIs) before (each quarter of year 2018) and during the COVID-19 pandemic (each quarter of year 2020). $\bf Results:$ During the first lockdown in Germany from mid-March until May 2020, PrEP-care appointments at WIR were postponed or canceled. Almost a third of PrEP users had discontinued their PrEP intake in the $2^{nd}$ quarter of 2020 due to alteration of their sexual behavior. The number of sexual partners decreased from a median of 14 partners in the previous 6 months in $1^{st}$ quarter of 2020, to 7 partners in $4^{th}$ quarter of 2020. Despite such a significant reduction in partner number during the pandemic in comparison to the pre-pandemic period, a steady rate of STIs was observed among PrEP users in 2020. \(\bf Conclusion:\9 The SARS-CoV-2-pandemic has impacted PrEP-using MSM in North Rhine-Westphalia with respect to their PrEP intake regimen and sexual behavior in 2020. Our study revealed a steady rate of STI among PrEP users even during the pandemic, thus highlighting the importance of ensuring appropriate HIV/STI prevention services in times of crisis
