Multitouch Experiment Instruction and Self-Regulation: Promoting Self-Regulation with a Multitouch Experiment Instruction on the topic of water analysis

In context of Education for Sustainable Development (ESD), the range of experiments offered by the Schülerlabor NanoBioLab at Saarland University was expanded to include an experiment on the topic of water analysis, which provided the basis of the intervention. In addition to the analogue experiment instruction, there is a digital version which is presented as a Multitouch Experiment Instruction (MEI). MEIs are digitally enriched, interactive experiment instructions that accompany the cognitive learning process of pupils and promote competencies in the digital world (Seibert et al., 2020). In this study, we analysed whether the MEI could support self-regulated learning in an indirect support approach by considering different hierarchical levels of self-regulation in the design of the materials. The results show a significant acquisition of self-regulatory competences of learners in grades ten and eleven by using the MEI compared to the analogue version

Multitouch Experiment Instructions to Promote Self-Regulation in Inquiry-Based Learning in School Laboratories

Multitouch experiment instructions (MEIs), implemented as interactive eBooks, are learning tools for pupils that offer various digital support tools and enable pupils to individualize their learning. They may be applied to contexts such as inquiry-based experiments in school laboratories, which involve highly demanding cognitive processes and require a high level of self-regulation. Self-regulation has been shown to be reliably promoted by interventions which include the targeted training of self-regulation strategies. A MEI was designed as an interactive eBook on experiments on the topic “Analysis of Cola”, suitable for an inquiry-based learning environment such as a school lab. The MEI’s potential to promote self-regulated learning was investigated by comparing it to a MEI with digital, integrated self-regulation training. The data revealed a significant increase of self-regulation in the control group, which consisted of pupils experimenting with the MEI on its own, and one experimental group, which included pupils that were supported by the MEI with an additional self-regulation training. It can be assumed that the MEI’s ability to promote self-regulated learning is comparable to the results achieved by an additional self-regulation training which explicitly addressed self-regulation strategies. This highlights the MEI’s potential to promote self-regulated learning in an indirect approach

Programmable code processor for software defined radio

This paper describes a flexible processor capable of producing binary codes for various standards such as UNITS and 802.11b. Its field of application lies in base-stations and in future software defined radio terminals. Because of its flexibility just one or two instances may be integrated into a SoC (System on Chip) where multiple codes are needed. This approach adds flexibility compared to a dedicated code generating structure where the class of codes is fixed. Specialized Bit-ALUs allow to address multiple bits of a register and to operate simultaneously on them. Instructions tailored for code generation enhance its efficiency considerably. The processor was successfully integrated and tested in a 0.25mum 5ML CMOS process
