Learning Logs

As learners increasingly use Web-based distance learning systems over years, large amounts of learning logs are generated. An instructor needs analysis tools to manage the logs and discover patterns within them to help improve instruction. A variety of analysis tools, including descriptive statistics, statistical inference, prediction, etc., can be utilized to analyze the effects of a teaching strategy from the logs. However, logs of a Web server, as learners' portfolios, cannot satisfy the requirements of these analysis tools. To resolve this problem, a data cube model is proposed as the infrastructure to store learning logs for analysis. We also describe the method of using query language to retrieve information from a database to construct the data cube. Furthermore, user-friendly operations for manipulating a data cube can retrieve statistical information from the data cube. Although statistical tools for managing Web logs exist, none specifically address the needs of the distance learning instructor. This article uses data cubes and database technology as fundamental analysis tools to satisfy a distance learning instructor's requirements for managing and analyzing learning logs.

Array Databases

AbstractMulti-dimensional arrays (also known as raster data or gridded data) play a key role in many, if not all science and engineering domains where they typically represent spatio-temporal sensor, image, simulation output, or statistics “datacubes”. As classic database technology does not support arrays adequately, such data today are maintained mostly in silo solutions, with architectures that tend to erode and not keep up with the increasing requirements on performance and service quality. Array Database systems attempt to close this gap by providing declarative query support for flexible ad-hoc analytics on large n-D arrays, similar to what SQL offers on set-oriented data, XQuery on hierarchical data, and SPARQL and CIPHER on graph data. Today, Petascale Array Database installations exist, employing massive parallelism and distributed processing. Hence, questions arise about technology and standards available, usability, and overall maturity. Several papers have compared models and formalisms, and benchmarks have been undertaken as well, typically comparing two systems against each other. While each of these represent valuable research to the best of our knowledge there is no comprehensive survey combining model, query language, architecture, and practical usability, and performance aspects. The size of this comparison differentiates our study as well with 19 systems compared, four benchmarked to an extent and depth clearly exceeding previous papers in the field; for example, subsetting tests were designed in a way that systems cannot be tuned to specifically these queries. It is hoped that this gives a representative overview to all who want to immerse into the field as well as a clear guidance to those who need to choose the best suited datacube tool for their application. This article presents results of the Research Data Alliance (RDA) Array Database Assessment Working Group (ADA:WG), a subgroup of the Big Data Interest Group. It has elicited the state of the art in Array Databases, technically supported by IEEE GRSS and CODATA Germany, to answer the question: how can data scientists and engineers benefit from Array Database technology? As it turns out, Array Databases can offer significant advantages in terms of flexibility, functionality, extensibility, as well as performance and scalability—in total, the database approach of offering “datacubes” analysis-ready heralds a new level of service quality. Investigation shows that there is a lively ecosystem of technology with increasing uptake, and proven array analytics standards are in place. Consequently, such approaches have to be considered a serious option for datacube services in science, engineering and beyond. Tools, though, vary greatly in functionality and performance as it turns out.

Significant Difference

The purpose of this study is to determine the demographic profiles of the respondents which are the teachers in Mindanao State University–Sulu according to gender and college, to identify the issues encountered by the MSU-Sulu Teacher towards modular distance learning approach, to distinguish the concerns of the MSU-Sulu Teacher towards modular distance learning approach, to investigate the teaching preparations on the adaptation of modular distance learning approach, and to identify the significant difference of issues and concern of the MSU-Sulu Teacher towards modular distance learning approach when they are grouped according gender and college. Frequency and percentage distribution, weighted arithmetic mean and independent t-test and chi-square are the statistical tools used to answer the entire research question. The data gathered was computed using SPSS analyzed and interpreted with the aide of the statistician. Descriptive survey method was used as the research method. This study utilizes 40 teachers from different colleges/department. Convenience sampling was used to It is the recommended number of which it is the 30% from the total population of all the faculty of Mindanao State University-Sulu.; questionnaire is used by the researcher as a research instrument of the study. The findings of the study were: 1) There is no significant difference of issues and concern of the MSU-Sulu teacher towards modular distance learning approach when grouped according gender but in contrary; and 2) There is significant difference on the issues and concern among MSU-Sulu teacher towards modular distance learning approach when grouped according colleges. The issues encountered towards modular distance learning approach were communication failure like that of instructions or confusion of students on the modules, limited teacher guidance, student’s in discourteous approach to teachers, complaints on not understanding the module, and all of which results to misbehavior on students and failure to pass worksheet on time. In addition, the concerns of the MSU-Sulu teacher towards modular distance learning approach were; first, hidden expenses on modules; second, teacher’s lack of media literacy; third, poor internet connection which intercepts communication between teacher and students; fourth, time constraint among teachers due to overload paperwork; fifth, equipment problem and complexity of the discussion as well as measurement of student’s performance; sixth,  managing student’s responses from time to time; seventh, teacher’s unavailability  and lastly, difficulties of studying among slow learners. Moreover, on teaching preparations on the adaptation of modular distance learning approach, the issues were cater and set time for student’s inquiries and be flexible to allow extension in terms of passing worksheets as well as allow parents, relative or even friends to pass worksheets in their behalf to lessen transportation expenses. Teachers must appreciate/ recognize his/her students to boost their confidence and avoid favouritism while being considerate to students who are attention seeker or may have ADHD. Correspondingly, the concerns were. Teachers must encourage handwritten answers to lessen plagiarism, on the absence of teacher, the parents and elders must guide the students in their learning at home. Teacher and parent’s guidance must go hand and hand in today’s learning. Teachers must likewise be flexible in finding solutions on printing shortage. And lastly, alternative teaching strategies like modular learning should be hone to aid lack of media literacy of both teacher and students In view of the findings and analysis, the following are recommended: Teachers must be flexible with the present kind of teaching strategy at all cost and at all aspects, Set guidelines as to establish proper communication among students and teachers, learning materials must be affordable as well as easy to understand content, teachers must develop their media literacy skills and encourage teachers to be available to their students on allotted time and cater all their inquiries with patience at all times. Furthermore, the following are the recommended research agenda: Teacher’s training on media literacy and module development programs to allow teamwork in the making process.
