This article describes a four-phased process used by the U.S. Navy for the systematic design and development of interactive videodisc (IVD) courseware (ICW). Phase One of the process, Analysis and Alternatives, describes the methodology for analyzing job/task data for the purpose of verifying the appropriateness of interactive videodisc as the medium of instructional choice, and for analyzing the proposed problem, and scoping out the approach and solution. Phase Two, System Design, describes the process for the layout and design of the IVD instructional product. Phase Three, System Development, discusses the process followed to actually develop and construct an IVD system. Lastly, Phase Four, System Test and Evaluation, will describe the formative evaluation process through which the IVD product and system is proven ready for use.

With increasing emphasis on streamlining the acquisition process, ground-test centers like the Arnold Engineering Development Center (AEDC) are re-evaluating their roles in the development of aerospace systems. Instead of merely providing data from ground-test facilities, the new emphasis challenges AEDC to become a team member that provides knowledge for risk management and decision making during the development and operation of an aerospace system. As a key link in the transition from a laboratory or design concept to an operational system, the capabilities of a ground-test center can provide a tremendous opportunity to reduce the time and cost involved in flight vehicle system development. AEDC has aggressively accepted the challenge and has developed an Integrated Test and Evaluation (IT&E) approach to support aerospace system development efforts. This paper focuses on an integrated test and evaluation process in a joint test and analysis effort between AEDC, the USAF Academy and Honeywell. This paper reports on the role of gas turbine engine/compressor numerical simulations in the test, analysis, and evaluation process in conjunction with an investigation to discern the effects of inlet swirl on the F109 turbofan engine performance and operability.

The problem of the quality of automated systems can be solved both from a common standpoint and from the standpoint of ensuring the quality of individual system components (software, information security tools, etc.). However, this leaves a number of particular questions due to the characteristics of a specific automated system. The occurrence of errors in the automated system for the preparation of aircraft flight data can lead to irreparable losses, the most damage is caused by design errors and incorrect general solutions implemented at the stage of system development. This necessitated the identification of specific principles of system design and development. The developed principles of designing an automated system consist, firstly, in determining its reference result, secondly, in identifying the main types of data and ensuring controlling their syntactic and semantic correctness, and, thirdly, in correct defining the boundaries of the system. The theoretical basis for the principles of the development of an automated system is the provisions of the systems approach, in particular, the new application of the system stratification tool. A typical automated data preparation system is considered as an example. It is shown that the use of the proposed principles allows avoiding or minimizing design errors and miscalculations and bringing the system representation stratification to a level that allows obtaining the necessary initial data and evaluating the quality indicators of the output data

Design Characteristics

Impairments of fingers, wrist, and hand forearm result in significant hand movement deficiencies and daily task performance. Most of the existing rehabilitation assistive robots mainly focus on either the wrist training or fingers, and they are limiting the natural motion; many mechanical parts associated with the patient’s arms, heavy and expensive. This paper presented the design and development of a new, cost-efficient Finger and wrist rehabilitation mechatronics system (FWRMS) suitable for either hand right or left. The proposed machine aimed to present a solution to guide individuals with severe difficulties in their everyday routines for people suffering from a stroke or other motor diseases by actuating seven joints motions and providing them repeatable Continuous Passive Motion (CPM). FWRMS approach uses a combination of; grounded-exoskeleton structure to provide the desired displacement to the hand’s four fingers flexion/extension (F/E) driven by an indirect feed drive mechanism by adopting a leading screw and nut transmission; and an end-effector structure to provide angular velocity to the wrist flexion/ extension (F/E), wrist radial/ulnar deviation (R/U), and forearm supination/pronation (S/P) driven by a rotational motion mechanism. We employed a single dual-sided actuator to power both mechanisms. Additionally, this article presents the implementation of a portable embedded controller. Moreover, this paper addressed preliminary experimental testing and evaluation process. The conducted test results of the FWRMS robot achieved the required design characteristics and executed the motion needed for the continuous passive motion rehabilitation and provide stable trajectories guidance by following the natural range of motion (ROM) and a functional workspace of the targeted joints comfortably for all trainable movements by FWRMS.

Operational Testing

Meaningful operational testing requires: a test plan which will lead to the measurement of critical human performance in a methodologically sound manner; an evaluation of the acceptability of the resulting measured performance; and a diagnosis of the causes of inadequate human performance. The Human Resources Test and Evaluation System (HRTES) is a method for aiding test planners and evaluators in the production of test plans, evaluations, and diagnoses which include a consideration of human performance. This paper consists of general descriptions of the problems of operational testing, the HRTES concepts for solving these problems, and the method for a formative evaluation of HRTES, itself.

A unique application of the Systems Approach to Training (SAT) was carried out for the design of the B-1 aircrew instructional system. A preliminary report was presented at the 1975 Human Factors Society Meeting by Johnson, et aI, (1974) and Sugarman, et aI, (1974). Based on the additional experience, this presentation will share with the training community a look at some of the strengths and weaknesses of the SAT process. The particular application provided a harsh test of the process since the B-1 air vehicle is still in the developmental stages. This resulted in many opportunities to be faced with missing or incomplete data whose criticality to the analysis became more than apparent. The genral state-of-knowledge within Instructional System Development (ISD) itself is incomplete, which also became apparent when applying a highly structured (i.e., internally consistent and documented) SAT process. The major strength of the SAT process is the capability it provides for the justification of many decisions that were hitherto prone to hand-waving. This particular strength comes from the internal documentation for each decision process which is an important feature of SAT. The adequacy of the assumptions underlying the decision processes then becomes subject to scrutiny. The power of the documentation is enhanced by the use of computer aids in data management and economic analysis which facilitate the documentation. Within the present paper, problem areas which weaken the SAT process are also discussed. These include the data bases for the task analysis and economic/policy data, the media selection process, and the development of instructional strategies.

This study aims to cover the current development of a platform for the disclosure of the Portuguese type design community, since the beginning of the desktop revolution, until today. 
To deepen our understanding, interviews were made to a selected and representative group of type designers from our sample based on several criteria. The interview tested six dimensions: people, processes, products, uses, identity and platform. The results analyzed in the last dimension, through content analysis and quantitative data, lead to the development of an online digital collaborative system – one of our specific objectives. 
Our hypothesis – that the development of a online digital collaborative system would allow further development of knowledge between products, users and authors, as well as, processes and uses – was also corroborated by the interviewers. 
Reviews have been made to reference international online projects to identify their purposes, areas of activity, objectives, mechanisms of interaction, usability and accessibility. This previous research brought together a set of notes that would become essential in the definition and development of our concept. 

The classification of typefaces is a subject of study by researchers and designers, but it is certainly not a topic for complete agreement. Organizing and balancing the content for the database was our first challenge since we were expecting users with good knowledge on the field, but also beginners. Several diagrams were put into test during the early stage of information architecture to better define categories, filters, and sorting methods, as well as users role in the system. The items and categories chosen were redefined in a second stage, and in the third stage hi-fidelity wireframes were produced, to concentrate on design aspects and decisions, and put the system into test and evaluation. 

The current results on the platform development, with the improvements made through several user tests, evaluations and refinements undertaken in all phases of the project have been crucial. We are expecting to run some pilot tests, as well as usability tests prior to the full implementation to further improve the system and meet the expectations.DOI: http://dx.doi.org/10.4995/IFDP.2016.3351

The Critical Thinking (CT) component has by now secured a key place within EFL curriculum aims and objectives. The integration of a CT dimension into the teaching of the writing skill in particular has received considerable attention in research. However, research has also pointed to the failure of assessment practices to evaluate CT development. It is within this context that the present work advocates a standard based approach to the assessment of CT in EFL writing that aligns assessment criteria to the critical abilities articulated in the learning outcomes (i.e., standards). This fosters a conception of CT measures that associates components of CT with higher order writing skills. Accordingly, the first objective of the study is to empirically test the relationship between CT dispositions and metacognitive strategy use in an attempt to establish a model of writing (self-)assessment that combines these two dimensions. As assessment is viewed as a formative evaluation process subservient of learning, the study also targets the students’ self-assessment strategies during the writing process. To this purpose, a questionnaire has been designed, and administered to 100 students at the Faculty of Letters and Human Sciences in Rabat to tap their perceptions and use of CT skills. The data analysis revealed that critical thinking development and assessment are metacognitive in nature; it follows that metacognitive skills such as planning, self-evaluating and reflecting are to be used as an essential vehicle in the development of Critical Thinking skills. This points to the paramount role of CT-informed formative (self-)assessment practices in benefiting ELT writing learners.

This research aims to develop interactive learning media for adobe flash-based prayer procedures/Tara (Tata Cara Shalat). Interactive media can develop prayer skills that are taught in the habituation process since the first grade of Madrasah Ibtidaiyah (MI).  This research used development research (RD) methods.  The development process in this study reached the stage of the formative evaluation process consisting of three steps, namely individual prototype material trials, small group trials, and field tryouts.  This field trial involved subjects in a larger class, involving 15-30 (a whole class of learners) or larger groups, namely the available classes.  The results of this field trial were used to make a product, material, or final design revisions. Interactive learning media can solve the problem of prayer skills regarding recitation and movement of prayer.  Thus, interactive learning media made it easier for students to understand the procedures for prayer quickly; besides, the learning process will be more enjoyable
