THE IMPACTS OF MULTIMEDIA LECTURES ON STUDENTS’ PERFORMANCE IN TWO SPECIFIC SUBJECTS

The objective of the work is to suggest pedagogical, economic and user-oriented criteria for the efficiency evaluation of multimedia lectures on mathematical methods in economics. Based on our previous work we describe them and suggest how to evaluate them including scales and measures, if possible. Then we concentrate on the pedagogical criteria and show their utilization for the efficiency evaluation of the multimedia lectures. For this purpose we divided the students into two groups based on the frequency of utilizing the multimedia lectures for their study, and used the methods of statistical analysis. In particular, we applied two-sample F-test to know whether the variances of students’ results are significantly different or not and an appropriate version of the t-test to know whether mean values of students’ results are significantly different or not. The case study is based on the data acquired form the students’ performance measurement in two specific subjects taught in the Czech University of Life Sciences Prague in 2010 and 2011

Measurement of the Valuation of Knowledge in Organizations: A Review Analysis

The purpose of this paper is to address the question of how to measure the value of knowledge in an organization. The study shows how to identify the attributes used to measure this value and identify the relationships between these attributes. As a first step, researchers chose selected 203 studies for review. Then those studies were analyzed through content and contextual analysis. It has been shown that it is possible to identify identical attributes across theoretical works and case studies that are aimed to assess the value of an investment in knowledge. The attributes can be defined and hierarchically structured. The paper provides the basis for establishing a broadly applicable methodology for assessing the value of the investment in knowledge and, consequently, improving the possibilities to determine its effectiveness

Students' Processing of Differently Structured Text Materials Focused on Agricultural Waste Disposal Using Eye-tracking

This study was focused on agricultural waste disposal (AWD) textual materials. Two educational texts are compared: designed texts traditionally with no purposeful design and structured knowledge texts, including the textual form of knowledge units. Eye-tracking technology is employed for retrieving the values of critical indicators specifying the way of reading the texts. We analysed users' visual attention and looking behaviour during the reading process. Thirty-three students worked with 45 pieces of educational texts accompanied by a didactic test. Statistical analyses show statistically significant differences neither in any indicator within studying the texts nor in the users' success rate in the didactic test. The users can work with the knowledge structured texts equivalently with the designed texts in the traditional way. The positive effect for AWD is that users can process knowledge structured texts with better results
