The base soil is one of the nature’s most common construction materials. Almost all types of construction are built with or upon the soil since centuries till today. The most important and effective part of a road pavement is sub grade soil, its strength and stability. If strength of soil is poor, then stabilization is normally needed. Sub grade is sometimes stabilized or replaced with stronger soil material so as to improve the strength. Such stabilization is also suitable when the available subgrade is made up of weak soil and hence has poor stability. Increase in the sub grade soil, strength may lead to economy in the structural thicknesses of a pavement. The most commonly used materials for soil stabilization are Cement, fly ash, lime, fibers, polymers etc. In the present study, an attempt has been made to improve the properties of the gravel soil by adding bitumen emulsion. An attempt has been made to use the emulsion for improving the strength of gravel soil expressed in terms of CBR values which may prove to be economical and give better results. In this study, the whole laboratory work revolves around the basic properties of soil and its strength in terms of CBR. A little cement added to provide better soil strength. It is observed that excellent soil strength results have been achieved by using cationic bitumen emulsion (CMS) with little quantity of cement used as filler. The appropriate mixing conditions for gravelly soil with CMS bitumen emulsion are being first attempted. This is followed by deciding four particular material conditions to show the variation in dry density and CBR value to achieve the best possible strength properties of gravel soil.
This paper reviews the use of Information and Communication Technology (ICT) by students of Distance Learning Centre, University of Ibadan, Nigeria. There is no doubt that ICT is playing a vital role in Open and Distance Learning (ODL) in terms of enhancing the provision of immediate assistant to the learners for their academic and administrative needs in large scale. It has been established that services cannot be performed in distance learning centres using traditional institutional system all alone. Therefore, ICT tools application has been incorporated to meeting the requirements of learners at various phases of learning cycle viz the admission phase and other services. The heterogeneous requirements in open distance learning has culminated into issues and challenges needed to be addressed in usage of the technologies and the service(s) being provided through ICT. Survey research design with the aid of questionnaire was employed to elicit response from the respondents. Simple random sampling technique was used to select the sample size of this work. The effectiveness, stimulating factors, issues and challenges confronting ICT usage, purpose as well as other challenges encountered by staff and students of University of Ibadan DLC were emphasised. Recommendations were made based on the findings.

Through the investigation and analysis of college students’ self-discipline in the new media environment, this paper summarizes the current situation and puts forward some feasible suggestions.
An Investigation of The Managerial Performances of Superiors and Organisational Commitments of Subordinates in School Systems
This study was conducted to reveal the interrelations between the managerial performances of the school principals as superiors, and organisational commitments and organisational citizenship behaviours of the subordinates as assistant principals and teachers with regards to selected presage variables. The participants were 636 persons including principals, assistant principals and teachers. Within a descriptive quantitative study, data was gathered by means of three quantitatively-oriented scales to determine the tendencies of the subordinates’ evaluations on the principals’ managerial performances. Variance analyses showed that school type, educational level, institutional status and occupational experience of the subordinates were considerably influential regarding the evaluations of the principals’ school-based management attainments. Moreover, only institutional status was found to be illuminative in explicating the evaluations on the managerial performances of the participatory school principals and subordinates’ (e.g., assistant principals) organisational commitment. Recommendations for further research are offered in the light of the outcomes of the current study, particularly, in the context of re-exploring the current issues with the assistant principals.
This study aims to analyze the relationship between the needs and general motivation of child convicts and family conditions of children. The results are used as a reference to determine the appropriate educational model towards moral life and character. The research sample of juvenile convicts who was assisted by the Bengkulu Special Class II Child Development Institution. The Edward Personal Preference Schedule (EEPS) test is used to determine the scale of the child’s needs related to the behavior they have done. Simple statistical analysis is used to analyze data. It is assumed that child convicts have a high potential or need to act criminally, because they have become convicts. The results of this study indicate that the aggressive potential of children is classified as moderate and low. Aggressive potential negatively correlates with Affiliate potential and Nurturance potential. They act criminal because of multi-factors.
Influence of home and school based factors on pupils academic performance at Kenya Certificate of Primary Education in Makadara sub-County, Nairobi County
The aim of primary education is to provide education at the basic level of all ongoing primary school pupils. This study was carried out to investigate influence of home and school based factors on pupil’s academic performers at Kenya certificate of primary education in Makadara sub-county, Nairobi County. The study adopted the ex-post facto design which involved the studies that investigate possible causes and effects by observing an existing condition and searching back in time for possible causal factors. It involved testing out possible antecedents of events that had happened and cannot be manipulated by the investigator. The study sampled 240 teachers, 39 Parents Association members and 150 pupils from class 6 and 7. The data collection instruments comprised of questionnaires and interview guide. Data collected was categorized, coded, analyzed then tabulated. The analysis was done using Statistical Package for Social Sciences (SPSS). The analysis was both qualitative and quantitative. Quantitative analysis considered use of frequency counts and distribution, tabulation totals and calculation of percentages aimed at generating the data collected into meaningful groups and frequency tables for further analysis. Qualitative analysis involved the conclusions from the respondents’ opinions. The study established that most parents had a college educational level, majority of the teachers were female whereas majority of the students were males. It also established that parental level of income influenced pupils’ performance in KCPE at 60%s. Physical facilities and teaching and learning resources were also cited as factors that highly influence performances. The researcher recommended that the parents should provide a conducive learning environment at home to give the pupils ample time and space to study. Parents ought to strive to provide the basic required learning materials that are vital for a good performance in the KCPE exam irrespective of their level of income. The government should endeavor…
This study examines the efficacy of the flipped learning model within a secondary English classroom at a large, urban high school in the Southeastern United States. To understand the effectiveness of the flipped learning model, the primary author conducted an action research study designed to answer the following research question: will students see more growth than their peers in reading comprehension because of the flipped learning model? Over the course of a month-long instructional unit, students in two eleventh grade English classes encountered instruction via the flipped learning model or from a more traditional approach before being tested on their reading comprehension. Those students taking part in flipped learning scored higher than their peers who received instruction from a more traditional approach. Although modest, these findings suggest that the flipped learning model is effective at promoting reading comprehension.
Alternative assessment is any type of assessment other than standardized tests/ achievement tests. Alternative assessments include observations, interviews, record reviews, and performance reviews that are less structured than formal assessments and may not be validated or tested for reliability. Examples of alternative assessments include portfolios, interest inventories, work samples, journals, observations, checklists, teacher made tests, and anecdotal records. This article pertains to the scoring of these types of alternative assessment using rubrics. As the title of this article implies, creating rubrics, rules for writing, scoring systems (checklists, rating scales, and holistic) will be provided along with a comparison of the three and errors that can be found that will decrease the validity of findings.
