The main goal of this study was to examine the extent to which different teaching instructions focused on the application of laboratory inquire-based experiments (LIBEs) and interactive computer based simulations (ICBSs) improved understanding of physical contents in high school students, compared to traditional teaching approach. Additionally, the study examined how the applied instructions influenced students' assessment of invested cognitive load. A convenience sample of this research included 187 high school students. A multiple-choice test of knowledge was used as a measuring instrument for the students' performance. Each task in the test was followed by the five-point Likert-type scale for the evaluation of invested cognitive load. In addition to descriptive statistics, determination of significant differences in performance and cognitive load as well as the calculation of instructional efficiency of applied instructional design, computed one-factor analysis of variance and Tukey's post-hoc test. The findings indicate that teaching instructions based on the use of LIBEs and ICBSs equally contribute to an increase in students' perform- * Note.The effects of laboratory inquire-based experiments and computer simulations 265 ance and the reduction of cognitive load unlike traditional teaching of Physics. The results obtained by the students from the LIBEs and ICBSs groups for calculated instructional efficiency suggest that the applied teaching strategies represent effective teaching instructions.
The Flipped Classroom (FC) is a teaching approach in which students gain the first-exposure learning with online materials outside the classroom, and then, in the classroom, they focus on interactive or engaging exercises. Despite its considerable publicity, the studies focused on the FC in primary education are deficient. The aim of this research is to determine efficiency and students’ involvement in the flipped Biology classroom in primary school, compared to the conventional classroom (CC) approach. Educational efficiency and students’ involvement are measured by combining the values of the students’ performance and mental effort on the test. Each task in the test was followed by the 5-point Likert scale for evaluation of invested mental effort. The total sample of this research included 112 students, aged from 12 to 13. The results show that the FC approach contributes to the reduction of the students’ mental effort and an increase in the students’ performance. On the basis of calculated efficiency and students’ involvement of applied teaching approaches, it was concluded that the FC represents a feasible and efficient approach to Biology primary education.

Primary school students generally lack motivation for learning physics, which they perceive as a difficult subject. In order to overcome this problem, it is necessary to apply appropriate teaching approach. The aim of this research was to assess the educational efficiency of mind maps in physics and students’ involvement when this approach is used. A pre-test – post-test control group design was used. The sample of this research consisted of 113 seventh-grade students divided into an experimental and a control group. The students in the experimental group were taught physics using mind maps and the students in the control group were taught using conventional teaching approach. The data were collected by using two physics knowledge tests and perceived mental effort scale. The data were analyzed using ANOVA, t-test and chi-square test. The obtained results showed that the educational efficiency of teaching with the use of mind maps was greater than the efficiency of conventional teaching approach. Besides that, the students’ involvement in the experimental group was higher than the one in the control group. The implementation of mind maps in teaching physics in primary schools can increase students’ motivation for learning physics and lower their mental effort.
Modern approaches in Physics classes which involve the game-based student response system (GSRS) have been in use for a while, but their educational efficiency and students’ involvement have not been examined. Therefore, this research’s main aim was to determine the educational efficiency and students’ involvement of GSRS and to assess their effect on scientific reasoning. The values of educational efficiency and students’ involvement were calculated based on students’ achievement and perceived mental effort. To determine these values, a pedagogical experiment with parallel groups was applied. The research was conducted on a sample of 172 secondary school students, and included material related to direct currents. The results point to positive and higher values of the educational efficiency and students’ involvement for GSRS approach than the conventional approach. It means that GSRS approach causes lower mental effort, letting more space generate in the working memory to perceive and process new information. The results also show a positive effect of GSRS on higher students’ engagement during the class and scientific reasoning. The obtained results undoubtedly indicate the positive effect of GSRS on the students’ performance. Therefore, GSRS approach should be used often in the classroom.

The present study explores the efficiency of the flipped classroom approach on English for Academic Purposes (EAP) students’ academic vocabulary acquisition in comparison with the conventional teaching approach. The efficiency is examined by evaluating students’ post-test performance, self-perceived mental effort employed in completing post-test tasks, and perceptions regarding the learning experiences. To this end, 60 undergraduates divided into flipped (E) and conventional (C) group participated in the survey. Quantitative data analysis revealed that the flipped classroom approach showed higher instructional efficiency than the conventional approach as the E group significantly outperformed the C group and reported investing considerably lower mental effort in completing the post-test tasks. In addition, the E group expressed significantly more positive perceptions toward the learning experience than the C group. Considering the positive results obtained in the study, the article points out the use of the flipped approach as an example of good practice for enhancing academic vocabulary acquisition in EAP context.
