The presented study analyzes the usage of the didactic efficiency of multiple representations in a computer environment in learning absolute value functions and equations. It is known that the axis of symmetry of the graph of the absolute value function is the y-axis. The research was applied at the University of Novi Sad, Serbia. The data were collected by testing a group of 226 students: major chemistry and physics students at the beginning of their common calculus course. The students worked individually in two groups: the experimental and control group. The experimental group of students practiced using GeoGebra software, and the control group of students practiced using paper and pencil. At the end of the experiment, which lasted for two weeks (six school classes), both groups were tested with a post-test of knowledge without using a computer. It can be concluded that GeoGebra software had a positive influence on the students’ achievements in solving absolute value equations.

The main purpose of this study is to determine the effect of experiential learning education on problem solving skills of primary education students.  Artificial wall climbing is considered as not only a game but also as a learning tool that can help children discover themselves, recognize their limits and their peers, make them actively involved, and lead them to experience. In this research, experimental model with pretest-posttest control group design was used. During this time, the experimental group joined exercise throughout six weeks twice a week and control group did not participate in any activities, continuing their usual life. For collecting data "Problem Solving Inventory for Children" was used. In the analysis of the research data, t-test was used to compare the pre-test, post-test results of the two groups. According to the results of statistical analysis, there were significant differences in pre-test and post-test scores regarding confidence, self-control, avoidance subscales and total scores. As a result of this research, it is argued that the applied artificial wall climbing program has a positive influence on the problem solving skills of students.

The objective of this study is to find out the effect of using mobile access (Audio Visual Easy Learn English) on students’ vocabulary achievement at SMPN 11 Kendari. Mobile  Access  (Audio  visual  easy  learn  English)  as  a media in learning teaching process. This research used quasi experimental design, the population is all seventh- grade students, and the sample is class VII1 as the experimental group and VII2as control group. The experimental group consisted of 30 students and control group consisted of 21 students. The research instrument consisted of 44 questions of vocabulary test. To collect the data, the researcher gave pre-test, taught by using Mobile Access  (Audio  Visual  Easy  Learn  English),  and  giving post-test. Mean score of post-tests (79.63) in experimental class is higher than pre-test score (59.66). While, in control class also has improvement but not too significant. It can be seen on post-test score (64.80) is higher than pre-test score (55.19). Based on the calculation of T-test, it shows that tcount = 3.775, while t-table =2.010 at level of = 0.05 with DF = 49. It means that tcount is higher than table, Therefore H0 was rejected and H1 was accepted. This can be concluded that  there  was a  significant  effect  of  using a significant effect using Mobile Access (Audio Visual Easy Learn English) on students’ vocabulary achievement at the seventh-grade students of SMPN 11 Kendari. Keywords: MA, Mobile Access, Audio Visual Easy Learn English, vocabulary achievement

The purpose of this study is to determine the effect of the "patience training program" on the patience and life satisfaction levels of university students. The study was organized as a pre-test, post-test experiment and control group design. For a total of 30 students from which were 17 in the control group and 17 in the experimental group, patience training was given for 5 weeks. The "Patient Scale" developed by Schnitker (2010) and adapted to Turkish by Eliüşük and Arslan (2016) and the "Life Satisfaction Scale" developed by Diener, Emmons, Larsen and Griffin (1985) and adapted to Turkish by Dağlı and Baysal (2016) were used as a data collection tool in the study. The "Wilcoxon" test was used for the comparison of in-group differences in the analysis of obtained data and the "Mann-Whitney U" test was used in examining the differences between the two groups. As a result of the study, it was observed that the patience and life satisfaction average scores of students in the experimental group receiving "patience training" increased significantly, while there was no significant difference in the patience and life satisfaction averages scores of the control group students.

The purpose of this research is to investigate the effects of Dora the Explorer cartoon on the spatial concept acquisitions and spatial abilities of the preschool children. The study was carried out with 80, 60-71 month old children attending preschools. Post-test only control group model is used in the research in order to identify the existing phenomena in a controlled manner. “The Bracken Basic Concept Scale, Third Edition: Receptive (BBCSIII:R) Form Direction/Position Subscale” and two different “Spatial Ability Games” were used to assess children’s spatial concept acquisitions and spatial abilities. Independent sample t-test was used in order to compare the average of post-test scores of the children in the experimental and control groups. According to the findings, it is found that there is meaningful difference between scores of post-tests of direction/position subscale and spatial ability games score. Comparing the scores of post-test of direction/position subscale and spatial ability games of experimental and control groups, it was found that there was a meaningful differentiation in favor of experimental group.

This study aims to investigate the possible effects of peripheral learning on elementary EFL learners’ grammar improvement: the case of prepositions of time and place. Two elementary classes were selected as experimental and control groups. Before beginning the treatment, a grammar test was administered to both the groups as a pre-test. Then, as treatment, the experimental group was exposed to realia, pictures, posters and texts, while the control group was not. After term-long treatment of 10 weeks, the two groups received the same grammar test as post-test. The results of t-test showed that the experimental group improved their grammar ability, i.e., knowledge of prepositions of time and place more than their friends in the control group. The finding of the study may open an optional path for teachers to include some peripheral materials in their teaching environment to further invest on unconscious learning abilities of the students.   Keywords: Peripheral learning, reposition of time, prepositions of place, grammar.
