“…The magnitude of the effect size, defined as the strength of the relationship in test results between the control and experiment classes [35]. Becker further said that effect size is defined as the difference in the average score of test results from the experimental and control classes divided by the combined standard deviation [36]. Becker went on to say that the effect size should be calculated using the formula Effect Size: D= ; the large classification of small effect size is: D<.15 (Negligible); .15<D<.40 (small effect size); .40<D<.75 (enough); .75<D<1.10 (High enough); 1.10<D<1.45 (high); D>1.45 (very high) [38].…”

Natural science learning achievement is an essential factor in learning outcomes. This research investigated an experimental study that aimed to improve concept science test result in online learning through Jigsaw cooperative learning model and learning style. The research involved the sample of 80 students from junior high school in South Jakarta, Indonesia divided into two groups: the experimental class and the class control. Raw data were statistically analyzed using the two-way variance technique at the .05 significance level. The findings revealed an effect between cooperative learning on natural science learning achievement, learning interest in natural science learning achievement, and interaction between cooperative learning and learning interest in natural science learning achievement. As a result, cooperative learning type Jigsaw shows a significant impact and had a good test result on natural science learning achievement. Therefore, the research suggests that Jigsaw cooperative learning is well suited to use as a learning model among junior high school students based on effect size test results.

The temporal change of soil chemistry in the forest floor and mineral soil down to a depth of 40 cm was assessed for the 102 permanent plots of the French Network for the Monitoring of Forest Ecosystems (RENECOFOR), over a 15-year period (from 1993–1995 to 2007–2012). In examining the separate and joint evolutions of a large set of parameters, many significant changes were detected reflecting the fact that French forest soils were not in a steady state. A significant increase in soil organic carbon (SOC) stocks was found, mainly in the surface soil (13.0% increase over the forest floor and the 0–10 cm layer). Conversely, the relative increase of the total nitrogen (Ntot) stocks was lower in the surface soil (4.8% increase), and a general and sharp decline of Ntot was detected between 10 and 40 cm depth (12.0% decrease). These results led to a substantial raise of C/N ratio over the whole soil profile. Another major finding is the difference in soil acidification recovery depending on the initial trophic level. In highly acidified contexts (top soil pH H2O < 4.5), increased soil acidification (pH and base saturation decrease, exchangeable Al increase) over the profile was observed while exchangeable base cation (Ca, Mg, K) pools increased. On the other hand, less acidic soils saw their global buffer capacity enhanced. These observations contrast with what is measured in other European inventories. While a previous study carried out on the same plots and over the same period highlighted SOC as a major driver of soil evolution in the top mineral soil, the possible mechanisms behind the large N decrease in the lower mineral soil remain to be confirmed.

Aims: The main objective of this study was to test competitive path models describing the relationship between Work-Home Interference, job burnout and job satisfaction. Study Design: Data was obtained from a sample of 95 dentists. A conceptual model in which burnout totally mediates the relationship between Work-Home Interference and job satisfaction was compared to another model in which this mediation was partial. The mediator role was demonstrated using the rationale and procedure suggested by Holmbeck [1]. The results were discussed in light of the literature dealing with burnout. Sample: Data was obtained from a sample of 95 denstists. Practical Implications: The research suggests the very importance of relationships between work and home life, and the mediator role of job burnout for current research in quality of work Original Research Article
