The demands on chemistry learning require hands-on action in the form of practicums to fit understanding chemical concepts, examine theories obtained and relate them everyday scientific phenomena through activities laboratory. So that cognitive, affective, psychomotor outcomes are achieved. This research is a type qualitative descriptive research. study investigates student perceptions Self-Reg...

Experience has shown that instructor-led trainings have some advantages that cannot easily be overcome by technology enhanced learning. Direct interaction with an instructor and among the group is often perceived as motivating and more personal. For small groups, in-class trainings can be more cost effective. On-line learning often requires a considerable amount of self-management and progress-...

Blended learning is a pedagogical approach which is designed to enhance complementarity between face-to-face and online learning (Dziuban et al., 2004). According to Qian et al.’s (Qian et al., 2016, p. 8) systematic review and meta-analysis “Blended learning appears to have a consistent positive effect in comparison with no intervention and appears to be more effective than or at least as effe...

We present B LEND H UNTER , a proof-of-concept deep-transfer-learning-based approach for the automated and robust identification of blended sources in galaxy survey data. take VGG-16 network with pre-trained convolutional layers train fully connected on parametric models COSMOS images. test efficacy transfer learning by taking weights learned using them to identify blends more realistic Canada-...

This paper presents a short overview of blended learning, showing arguments for and against these concepts. Potential blended learning scenarios are described that vary depending on the degree of instructor involvement, learner self-organisation and on-line moderation or coaching. The paper ends with an example of successful application of a blended learning concept in industry. Definition of B...

Before discussing the pathogenesis and clinical aspects of this disease, clarification of some of the pertinent terminological definitions may be in order. Hypertrophic emphysema is the most commonly used designation of this disease. Also, it is known under the following names: genuine emphysema, idiopathic emphysema, diffuse vesicular emphysema, obstructive emphysema, dystrophlc emphysema, pul...

Our question answering system was built with a number of priorities in mind. First, we wanted to experiment with natural language processing (NLP) technologies such as shallow parsing, named entity tagging, and coreference chaining. We felt that the small number of terms in the questions coupled with the short length of the answers would make NLP technologies clearly beneficial, unlike previous...

2 Principal contact: This year our primary goal was to improve on the performance of our TREC-8 system. In addition to improving the system directly, we worked on a number of tools to aid our development. We continued our work on a tool for automatic scoring of system responses, a “judge” program. We designed a tool for doing regression testing of question answering systems. W...
