This paper explores the potential of problem based learning and teams games tournaments model to improve students’ competencies. The objective of the study was to know the differences in the achievement of basic electrical and electronic competencies of students in terms of cognitive and psychomotor aspects using problem based learning model, teams games tournaments, and conventional learning. This was a quasi-experimental study. Instrument validity was measured through expert judgments and instrument reliability with Spearman Brown. Data collection used a pretest, a posttest, and skill observations. Data analysis techniques used one way ANOVA and a Tukey's post hoc test with a significance level of 0.05. The results revealed (1) differences in the achievement of basic electrical and electronic competencies of students in terms of cognitive and psychomotor aspects between using problem based learning, Teams Games Tournaments, and conventional learning, and (2) the results of the Tukey test showed the sequence of achievement of cognitive and psychomotor aspects of the best as follow: the model of teams games tournaments, problem based learning, and conventional learning.

<p class="Els-keywords">The purpose of this research is to determine whether there are differences in the understanding of the concept of students who learn by applying the model Problem Based Learning with Group Investigation. This research in to the type of quasi-experimental design of non-equivalent pretest-posttest control group. The samples taken were class XI IPA 2 (experimental class I) and class XI IPA 3 (experimental class II). The instrument applied was a learning outcome test containing 5 items. Data analysis was calculated using analysis techniques: descriptive and inferential. The results of the descriptive data obtained mean scores of 44.81 pretest and 76.54 posttest for the experimental class I, while the experimental class II scored 47.54 pretest and 84.14 posttest. From the independent sample test, it was obtained a sign score: 0.000 at a significance level of 5%. This means that H<sub>0 </sub>is rejected, so it was decided that the level of conceptual understanding for the model is Problem Based Learning different from the level of concept understanding in the model Group Investigation.</p>

Summary The variables impacting the efficiency of the offensive phase of the game in ice hockey may be determining factor for both the training process and game strategies. The research aimed to acquire and expand the knowledge about selected goal-scoring characteristics in the National Hockey League. A total of 511 even-strength goals were recorded in 129 randomly selected games in a regular-season 2020/2021 by indirect observation. Goals were differentiated by selected variable dimensions: location of the offensive team’s puck possession gain before scoring a goal, game situation preceding a goal, and the number of passes of the offensive team preceding a goal. Data were analyzed by performing a one–way ANOVA. Post hoc multiple comparisons were performed using the Tukey HSD test. The significance level of p ≤ 0.05 was used. Significant differences were found within all variable dimensions (p= 0.00001). In terms of the puck possession gain location, zone 1 (along the boards in the offensive zone) was the zone with the significantly highest mean score (p= 0.00305). Offensive zone play was significantly the game situation preceding most of the goals (p= 0.00000). The interval of the passes that preceded most of the recorded goals was the interval of 1 – 2 passes (p= 0.00000). Acquired results point out the dominance of particular variables and may help coaches to determine the content of the training process and game strategies. Based on the assumption of the realization of similar research in different environments in terms of the quality and age category, if the analogy would be found between the results of the present study and the results of potential studies, we can state the trends applicable to youth training.

OBJECTIVES: The present in vitro study was designed to compare the differences in the vertical misfit of implant-supported frameworks using three different forces for tightening the bridge locking screws: fastening by hand until first resistance, and using torque drivers with 10 and 20Ncm. METHODS: The investigation was conducted based on the results given by 9 six-unit nickel-chromium (2 abutments/ 4 pontics) screw-retained implant-supported frameworks. The structures were exposed to simulated porcelain firings. The marginal misfit measurements were made using a traveling measuring microscope at selected screw tightening forces: fastening by hand until first resistance, and using torque drivers with 10 and 20Ncm. The results were submitted to one-way ANOVA with repeated measures on one factor, and post hoc pairwise comparisons using Tukey test (5%). RESULTS: The mean marginal misfit of the frameworks, fastening the screws by hand until first resistance, was 41.56µm (SD±12.45µm). The use of torque driver devices caused a significant reduction in marginal opening (p<0.05). With the lowest torque available (10Ncm), the mean marginal discrepancy at the abutment-framework interface was reduced an average of 52% to a mean marginal opening of 19.71µm (SD±2.97µm). After the use of the 20Ncm torque driver, the mean marginal discrepancy of the frameworks was reduced an average of 69% to a mean marginal opening of 12.82µm (SD±4.0µm). Comparing the use of torque drivers with 10 and 20 Ncm torque, the means are not significantly different from one another. CONCLUSION: The seating force has an important effect on the vertical misfit measurements, once it may considerably narrow the vertical misfit gaps at the abutment-framework interface, thus leading to a misjudgment of the real marginal situation.

Objective: To evaluate the effect of ethanolic extracts of propolis (EEP) addition in different proportions to glass ionomer cement (GIC) on microleakage and microhardness of GIC. Study design: The cement was divided into four groups: one using the original composition and three with 10%, 25%, and 50% EEP added to the liquid and then manipulated. For microleakage assessment, sixty primary molars were randomly divided into four groups (n=15). Standard Class II cavities were prepared and then filled with EEP in different proportions added to GICs. Microleakage test was performed using a dye penetration method. The data were analyzed using one-way ANOVA and Mann - Whitney U tests (α = 0.05). Disc shaped specimens were prepared from the tested GIC to determine Vickers hardness (VHN). The data were analyzed using one-way ANOVA and post hoc Tukey test (α = 0.05). Results: There were no statistically significant differences between the groups in terms of microleakage (p &gt; 0.05). There were statistically significant differences between the VHN values of groups (p &lt; 0.05). Increasing addition of EEP to GIC statistically significantly increased VHN value of GIC (p &lt; 0.05). Conclusions: The addition of EEP to GIC increased the microhardness of the GIC and did not adversely affect the microleakage. Thus, it might be used during routine dental practice due to its antibacterial properties
