The purpose of this study was to investigate the comparative effects of prediction/discussion-based learning cycle (HPD-LC), conceptual change text (CCT), and traditional instructions (TI) on 8th grade students&rsquounderstanding of genetics concepts and on their perceived motivation and perceived use of learning strategies. This study was carried out during 2006-2007 fall semester at a public elementary school in Ankara. A total of eighty-one 8th grade students from three intact classes were involved in the quantitative part of this study. Students in the first and second experimental groups instructed with HPD-LC and CCT, respectively. The students in control group received TI. In the qualitative part, pre- and post-instructional interviews held with six students were interpreted by using a multidimensional interpretive framework of conceptual change. In this study the Genetics Concept Test was administered as pre-test, post-test, and delayed post-test in order to examine the effects of instructional strategies on students&rsquo
genetics understanding and retention. The Motivated Strategies for Learning Questionnaire was administered as pre-test and post-test to examine the effects of instructional strategies on students&rsquo
motivation and use of learning strategies. The results of mixed between-within subjects ANOVA revealed that students in both experimental groups understood the genetics concepts and retained their knowledge significantly better than students in control group. One-way MANOVA results revealed that HPD-LC students used elaboration strategies significantly more than CCT students. Interview analysis by considering ontological, epistemological, and social/affective perspectives of conceptual change indicated that some students from each group underwent conceptual change concerning the genetics concepts.

Citizens in contemporary societies are encountering more and more issues that are somehow related to science and technology. Therefore, science and technology education plays an important role in providing students with the knowledge and the competences they need in their life. The research and development project discussed in this chapter focuses specifically on scientific literacy. It is considered as a crucial element of multiple literacies required in modern life. These proficiencies are often referred to in terms such as information literacy, media literacy, environmental literacy, political literacy, computer literacy etc. (see e.g., Lankshear & Knobel, 2003). In order to enhance student scientific literacy the authors introduce a model of industry site visit for lower secondary school science education as a form of out-of-school learning. The potential of the site visit and other learning activities connected to it are discussed in the frameworks of scientific literacy, motivation and interest. The site visit and the activities, such as the use of ICT in reading and writing, are scrutinised with regard to the specified educational goals. The analysis of the motivational aspects of the site visit is based on self-determination theory. Self-determined learning could occur when an activity at a site is considered by a learner to be interesting, enjoyable, or personally valuable. Furthermore, the site visit offers role models which are critical for students’ choice of advanced studies and careers in science. Some empirical results on both cognitive and affective learning outcomes, as well as challenges that were encountered are presented on the basis of first design and evaluation cycle.

Agricultural production is one of the main factors affecting a country's domestic market situation. Many problems are the reasons for estimating crop yields, which vary in different parts of the world. Overuse of chemical fertilizers, uneven distribution of rainfall, and uneven soil fertility lead to plant diseases. This forces us to focus on effective methods for detecting plant diseases. It is important to find an effective plant disease detection technique. Plants need to be monitored from the beginning of their life cycle to avoid such diseases. Observation is a kind of visual observation, which is time-consuming, costly, and requires a lot of experience. For speeding up this process, it is necessary to automate the disease detection system. A lot of researchers have developed plant leaf detection systems based on various technologies. In this chapter, the authors discuss the potential of methods for detecting plant leaf diseases. It includes various steps such as image acquisition, image segmentation, feature extraction, and classification.

The global carbon and water cycles, and the process of photosynthesis are integral components of any high school science class or university science degree. Despite being intricately linked, these important global processes are often taught in isolation. This disconnection can lead to students having an incomplete understanding of the interconnection of leaf level processes, global cycles, and how they are affected by human activities. The “Global Change” app is an interactive teaching tool that illustrates how the biotic and abiotic systems involved in carbon and water cycling are connected to the stomata, and how human activities are affecting these processes in a meaningful way for students. In this chapter, the authors identify key gaps in students understanding and explain how the app addresses these. Example lessons are provided that encourage student self-inquiry, in a way that allows flexible, interactive learning. The Global Change app demonstrates how creative design and science can be combined to enhance the engagement of students with complex scientific concepts.

The focus of this paper is case and real-life problem-based (Ewell, 1997) experiential learning with computer information system projects at California State University Stanislaus. The experiential learning occurs within a four- stage cycle: concrete experience, reflective observation, abstract conceptualization, and active experime n-tation. The four principles and strategies applied to bring knowing and doing together are: concreteness, involvement, dissonance, and reflection. The paper shows how the four types of learning environments (affective, perceptually oriented, symbolic, behavioral) are implemented, and student teams guided. Multi-disciplinary aspects of experiential education, and drawbacks specific to the academic environment in assessing students’ performance in team projects are discussed.

Testo completoAbstract (sommario):
Abstract Well testing is one of the vital process as part of reservoir performance monitoring. As field matures with increase in number of well stock, testing becomes tedious job in terms of resources (MPFM and test separators) and this affect the production quota delivery. In addition, the test data validation and approval follow a business process that needs up to 10 days before to accept or reject the well tests. The volume of well tests conducted were almost 10,000 and out of them around 10 To 15 % of tests were rejected statistically per year. The objective of the paper is to develop a methodology to reduce well test rejections and timely raising the flag for operator intervention to recommence the well test. This case study was applied in a mature field, which is producing for 40 years that has good volume of historical well test data is available. This paper discusses the development of a data driven Well test data analyzer and Optimizer supported by artificial intelligence (AI) for wells being tested using MPFM in two staged approach. The motivating idea is to ingest historical, real-time data, well model performance curve and prescribe the quality of the well test data to provide flag to operator on real time. The ML prediction results helps testing operations and can reduce the test acceptance turnaround timing drastically from 10 days to hours. In Second layer, an unsupervised model with historical data is helping to identify the parameters that affecting for rejection of the well test example duration of testing, choke size, GOR etc. The outcome from the modeling will be incorporated in updating the well test procedure and testing Philosophy. This approach is being under evaluation stage in one of the asset in ADNOC Onshore. The results are expected to be reducing the well test rejection by at least 5 % that further optimize the resources required and improve the back allocation process. Furthermore, real time flagging of the test Quality will help in reduction of validation cycle from 10 days hours to improve the well testing cycle process. This methodology improves integrated reservoir management compliance of well testing requirements in asset where resources are limited. This methodology is envisioned to be integrated with full field digital oil field Implementation. This is a novel approach to apply machine learning and artificial intelligence application to well testing. It maximizes the utilization of real-time data for creating advisory system that improve test data quality monitoring and timely decision-making to reduce the well test rejection.

Testo completoAbstract (sommario):
The Type 23 Frigate (T23) has been extended in-service well beyond its initial design life of 18 years, with some ships due to be over 35 years old when they leave service. To ensure the vessels remain effective and available a T23 Life Extension (LIFEX) programme was set up to meet this revised End of Life (EOL). A significant element of this LIFEX and the focus of this paper is PGMU (Power Generation and MCAS Update). The aim of PGMU is to restore electrical power margins and to overcome equipment obsolescence. This requirement was set with the obvious constraint that new equipment must integrate with the existing ship and it’s supporting systems without adversely affecting key operational characteristics. Considered an Alteration and Addition (AandA) but the largest the T23 has ever seen, the project has encompassed the entire cradle to birth cycle and equipment is currently being fitted into the first of class with a plan to achieve sea trials in Q2 2019. PGMU will replace the most critical assets of a warship; its power generation system. It replaces the 4 diesel generators with higher power units, the replacement of the 2 motor generator sets that supply the 440v ship services, upgrades the switchboards as well as the Machinery Controls and Surveillance System (MCAS). Challenges have come in the form of structural limitations; stability management; signature management; physical integration and the re-designing of a legacy platform to new standards. This paper builds on one that I presented at INEC 2016: “Facing the challenges of integration and physical constraints when replacing major equipment in old platforms”. This edition will cover issues that have arisen in the later stages of the design and validation through into the integration for First of Class (FoC); HMS Richmond. It will concentrate on the naval architectural aspects of the project and will consider how they were managed whilst offering an overview of some of the key learning from experience (LFE) that has been gained.
