Evaluating the Use of 3D Visualization Technology in Geology Education
Information systems can contribute to the success of students in engineering and science. In this study, 3-D visualizations that create a realistic map of rock structures are used to aid students in developing the spatial intuition to understand geological processes. This technology received positive ratings for learning outcomes and within the technology acceptance model. In addition, qualitative data provides additional detail about what features are correlated with the success of direct manipulation visualizations. The qualitative data suggest that the interface design may be a moderator of the relationship between the completeness of the visualization and how much individuals can benefit from the visualization
Evaluating complex digital resources
Squires (1999) discussed the gap between HCI (Human Computer Interaction) and the educational computing communities in their very different approaches to evaluating educational software. This paper revisits that issue in the context of evaluating digital resources, focusing on two approaches to evaluation: an HCI and an educational perspective. Squires and Preece's HCI evaluation model is a predictive model ‐ it helps teachers decide whether or not to use educational software ‐ whilst our own concern is in evaluating the use of learning technologies. It is suggested that in part the different approaches of the two communities relate to the different focus that each takes: in HCI the focus is typically on development and hence usability, whilst in education the concern is with the learner and teacher use

Using Augmented Reality as a Medium to Assist Teaching in Higher Education
In this paper we describe the use of a high-level augmented reality
(AR) interface for the construction of collaborative educational applications
that can be used in practice to enhance current teaching
methods. A combination of multimedia information including spatial
three-dimensional models, images, textual information, video,
animations and sound, can be superimposed in a student-friendly
manner into the learning environment. In several case studies different
learning scenarios have been carefully designed based on
human-computer interaction principles so that meaningful virtual
information is presented in an interactive and compelling way. Collaboration
between the participants is achieved through use of a
tangible AR interface that uses marker cards as well as an immersive
AR environment which is based on software user interfaces
(UIs) and hardware devices. The interactive AR interface has been
piloted in the classroom at two UK universities in departments of
Informatics and Information Science
Seafloor characterization using airborne hyperspectral co-registration procedures independent from attitude and positioning sensors
The advance of remote-sensing technology and data-storage capabilities has progressed in the last decade to commercial multi-sensor data collection. There is a constant need to characterize, quantify and monitor the coastal areas for habitat research and coastal management. In this paper, we present work on seafloor characterization that uses hyperspectral imagery (HSI). The HSI data allows the operator to extend seafloor characterization from multibeam backscatter towards land and thus creates a seamless ocean-to-land characterization of the littoral zone
Revision and Manipulation of Physical Models as Tools for Developing the Aquifer Model by Preservice Elementary Teachers
Citizens show misunderstandigs about groundwater that hinder making informed decisions about problems such as the deterioration of aquifers and clean water supply. Science education should address this, including modelling practices about the aquifer model, along with a representation of the model, for example, as a physical model. Physical models have been extensively used in geology teaching, but students rarely construct, evaluate or manipulate them. This study addressed how the revision and manipulation of physical models contributed to the construction of a complete aquifer model by 80 Preservice Elementary Teachers (PETs) of two cohorts (subsequent years) that participated in a modelling teaching sequence that included fieldwork and the construction of a physical model. The model representations (drawings, writings, oral expressions, physical models) were analysed, based on Components-Mechanisms-Phenomena systems thinking framework, through a constant comparison method. Results show that, although PETs improved their models both years, it was in Year 2 when they improved the Phenomena dimension. PETs that constructed a complete model tripled those of Year 1. The conversations in groups and the model representations throughout the sequence show that the evaluation of the physical model when comparing it with reality during the field trip, and the manipulation of the physical models guided by teachers´ scaffoldings to encourage PETs to make representations and predictions, led them to revise and improve their models in Year 2. Therefore, we conclude that it is indeed the manipulation and revision of physical models that provides opportunities for revising the aquifer model and improving it.This work was supported by the Euskal Herriko Unibertsitatea [grant number GIU19/008]

A Review of application building information modeling (BIM) during pre-construction stage: retrospective and future directions
Pre-construction is one of the biggest areas of risk and uncertainty in construction
project as it deals with subsurface ground conditions information. The amount of detail data
needed in pre-construction especially for existing data modelling and site analysis should be
sufficient enough to ensure that significant risks could not reasonably be anticipated. Current
practicing method in interpreting data during this stage tasks reveal limitation. Construction
industry faced many obstacles due to the depends on the traditional practice; paper-based
document which missing and redundant data always happened. In recent years, there has been a
shift in construction where people move to BIM application because of its potential to reduce
the problem faced by infrastructure world. BIM has become a successful technology and
widely popular in the construction world especially in developed countries because of its
potential. Nowadays, people are moving one step ahead in BIM which is adoption of BIM
during pre-construction stage. Thus, this paper review studies centered on BIM-integrated
modelling during preconstruction stage. But there is lack of practical researches have been
made during this stage. Although a large number of studies on BIM have been conducted in the
past decade, a lack of consensus remains among researchers and practitioners regarding the
applications of BIM during pre-construction stage, the availability of subsequent data
integration tool for geotechnical activity. A comprehensive literature review was conducted for
data collection and analysis. After in-depth review of journal articles widely cover the
application of BIM, this study summarizes an overview and critical reflection of geotechnical
data integration using BIM during pre-construction stage. The results are useful for the
identification of research clusters and topics in the BIM community
