Abstract This article presents the results of analysis of Czech and Russian textbooks intended for organic chemistry teaching at upper secondary schools. In principle, the estimation of textbook didactic capacity is based on decomposition of the textbook content into a set of different objects and their subsequent frequency analysis. In this study, three Czech textbooks and three Russian textbooks were characterized by particular and total didactic capacity coefficients. The indifference of the calculated didactic capacities was tested by chi-square statistics at a level of significance α = 0.05. The results show that the selected Czech and Russian textbooks are not significantly different.

In the research, a quantitative method intending to evaluate didactic capacity of four textbooks of organic chemistry used at upper secondary schools has been applied. Focusing on the arrangement of verbal and non-verbal elements, two Czech textbooks of organic chemistry were compared with two adequate Russian textbooks. The textbooks were characterized by coefficients of subject presentation, education control, orientation, and the total didactic capacity. Based on chi-square statistics, significance of the results is discussed and critically interpreted. Keywords: didactic capacity, analysis of textbooks, educational mean, Czech and Russian textbooks, organic chemistry.

PurposeThis study aimed to examine the effects of Cambodia's New Generation Schools (NGS), as compared to their traditional counterparts, in enhancing the seven constructs: (1) science and math achievement, (2) science and math self-efficacy, (3) science and math outcome expectations, (4) attitudes toward science, (5) interactive science and math lessons, (6) support from science and math teachers and (7) encouragement and support in science from family.Design/methodology/approachThe two observations data was collected using self-rated questionnaire from 301 11th graders from five upper secondary schools located in three provinces of Cambodia. Independent sample t-test, Analysis of Covariance (ANCOVA) and dependent sample t-test were used to analyze the repeated measures data.FindingsThe study revealed that students from the NGS exhibited statistically higher scores for most constructs, especially for attitudes toward science. However, when controlling for the differences in the first observation data, the significant effects of the three constructs have been neutralized. Moreover, though there was an increase in science activities outside school, there was a negative trajectory in the other two sub-constructs of attitudes toward science and support from science and math teachers, both in NGS and traditional schools.Practical implicationsThese findings point some practical implications for enhancing the effectiveness of the two school types and further research.Originality/valueThere is heavy investment in new form of schools across the world to enhance students' learning and academic achievement in science and math in K-12 and to promote their interest in STEM in higher education. However, there is little document on the effectiveness of this new form of school, particularly in the Cambodian context.
