The paper presents a study that focuses on the issue of sup-porting educational experts to choose the right combination of educational methodology and technology tools when designing training and learning programs. It is based on research in the field of adaptive intelligent e-learning systems. The object of study is the professional growth of teachers in technology and in particular that part of their qualification which is achieved by organizing targeted training of teachers. The article presents the process of creating and testing a system to support the decision on the design of training for teachers, leading to more effective implementation of technology in education and integration in diverse educational contexts.

Tanulmányunkban a hazai vállalatok teljesítménymérési és teljesítménymenedzsment gyakorlatát vizsgáljuk a Versenyben a világgal kutatási program 2009. évi felmérése adatainak felhasználásával. Célunk a döntéstámogatás hátterének vizsgálata: a vállalatok teljesítménymérési gyakorlatának jellemzése, konzisztenciájának értékelése, vizsgálva a korábbi (1996, 1999 és 2004 évi hasonló) kutatásaink során megfigyelt tendenciák további alakulását is. A vállalati teljesítménymérés gyakorlatát, a vállalatvezetők által fontosnak/hasznosnak tartott, illetve rendszeresen használt információforrásokat, teljesítménymutatókat, elemzési eszközöket a korábbi kutatásainkhoz kialakított elemzési keret (orientáció, egyensúly, konzisztencia, támogató szerep) felhasználásával értékeltük. Az információs rendszer különböző tevékenységeket támogató szerepének az értékelése során a különböző területekért felelős vezetők véleményét is összevetettük, s különböző vállalati jellemzők (vállalatméret, tulajdonosok típusa, fő tevékenység stb.) sajátosságait is vizsgáltuk. ___________ The paper analyses the performance measurement and performance management practice of Hungarian companies, based on the data of the Competitiveness research program (2009). Our goal was to evaluate the practice from the point of view of decision support, based on our previous framework, evaluating the orientation, the balance, the consistency and the supporting role of the performance measurement practice.

A tanulmány a vezetői döntéshozatal három lényeges aspektusát tárja fel. A Versenyben a világgal c. kutatási program eredményei alapján arra lehet következtetni, hogy a menedzserek döntéshozatali képességei és megközelítései, a vállalati teljesítménymérés és menedzsment döntéseket támogató szerepe, valamint a vállalatok érintettekhez fűződő viszonya meghatározó lehet a hatékony vezetői döntéshozatal során. A vállalati döntéshozatal jellemzőinek bemutatása után megvizsgáljuk azt is, hogy a különböző teljesítményű cégek döntéseit mennyire támogatja a menedzserek felkészültsége, a teljesítménymérési gyakorlat és az érintettek elvárásai. A szerzők úgy találták, hogy a fenti tényezők mindegyike hozzájárul a hazai cégek versenyképességéhez, általánosságban ugyanis elmondható, hogy a döntéseket támogató vállalati környezet jobb üzleti teljesítményhez és gyorsabb reagálóképességhez vezethet. Az eredmények összegzése mellett ajánlásokkal is éltek a vállalatok számára, amelyek alkalmazásával hatékonyabb döntéseket hozhatnak. _______ This study presents three main aspects of the managerial decision making. Based on the results of the research program In competition with the World it points to the fact that decision making abilities and approaches of the managers, the corporate performance appraisal and the management decision support role, and the corporate relations to the stakeholders will be determinant in the process of the efficient managerial decision making. After presentation of characteristics of the corporate decision making the authors examine that how the decisions of enterprises with different performances are supported by the preparedness of the managers, the performance appraisal practice and the stakeholders expectations. The authors have thought that every factor contributes to the competitiveness of the domestic enterprises, and generally the decision supporting corporate environment can lead to better business performance and faster responsive abilities. Besides the results summary the authors give useful recommendations to the corporations with which they can make more efficient decisions.

Beginning teachers in the field of English Language Arts and Reading are responsible for providing literacy instruction to students. Teachers need a broad background in teaching reading, writing, listening, speaking, and viewing, as well as critical thinking. In secondary schools in particular, beginning English Language Arts and Reading teachers are also faced with the challenge of preparing students to be proficient enough readers and writers to meet required State standards. Beginning teachers must navigate compelling challenges that exist during the first years of teaching. The school support systems available to new teachers are an integral part of their educational development. ^ This qualitative study was conceptualized as an in-depth examination of the experiences and perceptions of eight beginning teachers. They represented different racial/ethnic groups, attended different teacher preparation programs, and taught in different school cultures. The data were collected through formal and informal interviews and classroom observations. A qualitative system of data analysis was used to examine the patterns relating to the interrelationship between teacher preparation programs and school support systems. ^ The experiences of the beginning teachers in this study indicated that teacher education programs should provide preservice teachers with a critical knowledge base for teaching literature, language, and composition. A liberal arts background in English, followed by an extensive program focusing on pedagogy, seems to provide a thorough level of curriculum and instructional practices needed for teaching in 21st century classrooms. The data further suggested that a school support system should pair beginning teachers with mentor teachers and provide a caring, professional environment that seeks to nurture the teacher as she/he develops during the first years of teaching. ^

Online learning systems (OLS) have become center stage for corporations and educational institutions as a competitive tool in the knowledge economy. The satisfaction construct has received extensive coverage in information systems literature as an indicator of effectiveness but has been criticized for lack of validity; yet, the value construct has been largely ignored, although it has a long history in psychology, sociology, and behavioral science. The purpose of this dissertation is to investigate the value and satisfaction constructs in the context of OLS, and their perceived by learners relationship for implied effectiveness of OLS. ^ First, a qualitative phase is employed to gather OLS values from learners' focus groups, followed by a pilot phase to refine a proposed instrument, and a main phase to validate the survey. Responses were received from 75 students in four focus groups, 141 in the pilot, and 207 the main survey. Extensive data cleaning and exploratory factor analysis were done to identify factors of learners' perceived value and satisfaction of OLS. Then, Value-Satisfaction grids and the Learners' Value Index of Satisfaction (LeVIS) were developed as benchmarking tools of OLS. Moreover, Multicriteria Decision Analysis (MCDA) techniques were employed to impute value from satisfaction scores in order to reduce survey response time. ^ The results provided four satisfaction and four value factors with high reliability (Cronbach's α). Moreover, value and satisfaction were found to have low linear and nonlinear correlations, indicating that they are two distinct uncorrelated constructs. This is consistent with the literature. Value-Satisfaction grids and the LeVIS index indicated relatively high effectiveness for technology and support characteristics, relatively low effectiveness for professor's characteristics, while course and learner characteristics indicated average effectiveness. ^ The main contributions of this study include identifying, defining, and articulating the relationship between value and satisfaction constructs as assessment of users' implied IS effectiveness, as well as assessing the accuracy of MCDA procedures to predict value scores, thus reducing by half the survey questionnaire size. ^
