Data Annotation

Big data bioinformatics aims at drawing biological conclusions from huge and complex biological datasets. Added value from the analysis of big data, however, is only possible if the data is accompanied by accurate metadata annotation. Particularly in high-throughput experiments intelligent approaches are needed to keep track of the experimental design, including the conditions that are studied as well as information that might be interesting for failure analysis or further experiments in the future. In addition to the management of this information, means for an integrated design and interfaces for structured data annotation are urgently needed by researchers. Here, we propose a factor-based experimental design approach that enables scientists to easily create large-scale experiments with the help of a web-based system. We present a novel implementation of a web-based interface allowing the collection of arbitrary metadata. To exchange and edit information we provide a spreadsheet-based, humanly readable format. Subsequently, sample sheets with identifiers and metainformation for data generation facilities can be created. Data files created after measurement of the samples can be uploaded to a datastore, where they are automatically linked to the previously created experimental design model.

Our PCR Simulator is a web-based application designed to introduce concepts of multi-factorial experimental design and support teaching of the polymerase chain reaction. Learners select experimental settings and receive results of their simulated reactions quickly, allowing rapid iteration between data generation and analysis. This enables the student to perform complex iterative experimental design strategies within a short teaching session. Here we provide a short overview of the user interface and underpinning model, and describe our experience using this tool in a teaching environment.

Interactive Web-based tutorials were developed as a supplement to lectures in an introductory statistics class. A quasi-experimental design compared learning outcomes of students who attended one of two classes that offered the tutorials to students as an extra-credit course option to those who attended a lecture-only class. Analysis of critical items on five course exams revealed that students who attended the classes with tutorials scored higher on four out of five topics covered by the tutorials than students who attended the lecture-only class. Tutorial use leading to mastery of the concepts was associated with exam performance on the critical items. These findings suggest that Web-based tutorials can be an effective supplement to class lectures for enhancing student learning.

This chapter introduces inquisitivism as an approach for designing and delivering Web-based instruction that shares many of the same principles of minimalism and other constructivist approaches. Inquisitivism is unique in that its two primary or first principles are the removal of fear and the stimulation of an inquisitive nature. The approach evolved during the design and delivery of an online full-credit university course. The results of a quasi-experimental design-based study revealed that online students in the inquisitivism-based course scored significantly higher on their final project scores, showed no significant difference in their satisfaction with their learning experiences from their face-to-face (F2F) counterparts, and had a reduction in fear or anxiety toward technology. Finally, the results revealed that there was no significant difference in final project scores across the personality types tested. The author hopes that inquisitivism will provide a foundation for creating effective constructivist-based online learning environments.

The purpose of this study was to determine the effects of using multimedia web-based on learning outcome, especially psychomotor domain of XI Fashion Boutique students in SMKN 6 Surabaya, on the subject study Pattern Making. Quasi-Experimental design has been used, which consists of experimental class (multimedia web-based) and control class (power point), wherein consists of 30 students for each class. Data was analyse using Independent sample t-test on SPSS software. The data showed that psycomotor domain of the experimental class were higher than control class.

The purpose of this empirical study was to explore the interactional commenting patterns that EFL learners produced in web-based peer feedback and correlate them with the learners’ writing achievement. The study employed a quasi-experimental design built on the Theory of Cognitive Apprenticeship (Collins, 1991), which gives emphasis on coaching (local revision) and scaffolding (global revision) processes. The context of the study was in a public university in Oman and 50 participants were involved in a selected range of online peer-feedback processes, synchronously and asynchronously. A paired samples t-test showed that students were able to improve their grammar range and accuracy in writing essays more than other scaling categories (e.g. content and organization). The results of the qualitative analysis indicated that students produced far more comments synchronously than asynchronously, and most of the students’ exchanges were on forms. The findings of this study could be a practical reference for those who plan to cultivate the use of technology in peer feedback practice.

1AbstractA recent stream of alarmist publications has questioned the validity of published neuroimaging findings. As a consequence, fMRI teams worldwide have been encouraged to increase their sample sizes to reach higher power and thus increase the positive predictive value of their findings. However, an often-overlooked factor influencing power is the experimental design: by choosing the appropriate experimental design, the statistical power of a study can be increased within subjects. By optimizing the order and timing of the stimuli, power can be gained at no extra cost. To facilitate design optimization, we created a python package and web-based tool called Neurodesign to maximize the detection power or estimation efficiency within subjects, while controlling for psychological factors such as the predictability of the design. We implemented both a simulation-based optimisation, as well as an optimisation using the genetic algorithm, introduced by Wager and Nichols (2003) and further improved by Kao et al. (2009), to optimize the experimental design. The toolbox Neurodesign allows more complex experimental setups than existing toolboxes, while the GUI provides a more user-friendly experience. The toolbox is accessible online at www.neuropowertools.org.

AbstractGiven the many types of suboptimality in perception, I ask how one should test for multiple forms of suboptimality at the same time – or, more generally, how one should compare process models that can differ in any or all of the multiple components. In analogy to factorial experimental design, I advocate for factorial model comparison.
