Did you hear that students' knowledge of multiplication basic facts improved decidedly between the second national mathematics assessment in 1978 and the third assessment in 1982 (NAEP 1983)? Average scores of nine-year-olds rose from 60 percent to 66 percent, ranging from 70–85 percent on easier facts to 50–60 percent on harder facts. Fourth graders performed about forty percentage points better than third graders. By age thirteen. scores were 90 percent or above on both assessments. That's the good news. The bad news is that results were not as good for conceptual, computational. or problem-solving items.

The Relationship

This paper studies the relationship between civil war and the value of firms in a poor, resource-abundant country using microeconomic data for Angola. We focus on diamond mining firms and conduct an event study on the sudden end of the conflict, marked by the death of the rebel movement leader in 2002. We find that the stock market perceived this event as “bad news” rather than “good news” for companies holding concessions in Angola, as their abnormal returns declined by 4 percentage points. The event had no effect on a control portfolio of otherwise similar diamond mining companies. This finding is corroborated by other events and by the adoption of alternative methodologies. We interpret our findings in light of conflict-generated entry barriers, government bargaining power, and transparency in the licensing process. (JEL D74, G32, O13, O17, Q34)

An optimistic learning bias leads people to update their beliefs in response to better-than-expected good news but neglect worse-than-expected bad news. Because evidence suggests that this bias arises from self-concern, we hypothesized that a similar bias may affect beliefs about other people’s futures, to the extent that people care about others. Here, we demonstrated the phenomenon of vicarious optimism and showed that it arises from concern for others. Participants predicted the likelihood of unpleasant future events that could happen to either themselves or others. In addition to showing an optimistic learning bias for events affecting themselves, people showed vicarious optimism when learning about events affecting friends and strangers. Vicarious optimism for strangers correlated with generosity toward strangers, and experimentally increasing concern for strangers amplified vicarious optimism for them. These findings suggest that concern for others can bias beliefs about their future welfare and that optimism in learning is not restricted to oneself.

There are lots of alternative investing. It is started from investment real assets, securities, from conventional and manifold sharia. Islamic Capital market and conventional have some type securities which have different risk level of risks. A stock is one of securities among other securities that have the high level of risk. One of the risks that exists in the stock is fluctuations price, it is commonly called as volatility. The aim of this research is to identifiy the risk of sharia stock and conventional stock in Indonesia Stock Exchange (BEI) by using Jakarta Islamic Indekx (JII) and LQ45 Indeks variabels. In our research, we use time series started on 1 January 2015 to 10 October 2016 from yahoo finance with ARCH/GARCH and EGARCH models processed by Eview 8. Based on research finding with GARCH and EGARCH, this research tends to EGARCH. The fist finding shows that volatility stock JII lower, 0,075 than LQ45 0,0316. If volatility is higher, it means the stability degree lower. Both of those stocks are dominated by bad news and good news. Between JII and LQ45, the news respon is higher on LQ45. It means the volatility risk impact higher on LQ45. The third finding is the JII forecasting results through EGARCH has refrection proportion JII has smaller 0,194 than LQ45 0,678. It means that JII volatility is lower than LQ45.

The present research demonstrates how consumer responses to negative and positive offers are influenced by whether the administering marketing agent is an Artificial Intelligence (AI) or a human. In the case of a product or service offer that is worse than expected, consumers respond better when dealing with an AI agent in the form of increased purchase likelihood and satisfaction. In contrast, for a better than expected offer, consumers respond more positively to a human agent. We demonstrate that AI agents, in comparison to human agents, are perceived to have weaker intentions when administering offers, which accounts for this effect. That is, consumers infer that AI agents lack selfish intentions in the case of an offer that favors the agent and lack benevolent intentions in the case of an offer that favors the customer, thereby dampening the extremity of consumer responses. Moreover, we demonstrate a moderating effect such that marketers may anthropomorphize AI agents to strengthen perceived intentions, providing an avenue to receive due credit from consumers when providing a better offer and mitigate blame when providing a worse offer. Potential ethical concerns with the use of AI to bypass consumer resistance to negative offers are discussed.

Third and fifth graders were given a sequence of number pairs and asked ro discover the function rule relating them, test the hypothesis, and generalize it to other instances. The fifth graders were better than the third graders on all performance criteria. Task difficulty depended on the funcuon. Some functions were easier when presented in a graphic mode, others in a symbolic mode. Whether inferences made use of abscissa-ordinate pairs, in contrast to a sequence of ordinate values, appeared to depend on both function and mode of presentation. Unlike adults, the children seemed ready to relinquish a hypothesis in the face of disconfirming evidence.

Drill And Practice

A flash card procedure was designed with some of the features of microcomputers for the drill and practice of basic facts. Second, third, and fourth graders followed the same daily routine for 6 weeks in either a flash card or a microcomputer condition, practicing basic facts in subtraction or division. Weekly tests revealed learning in the first 2 weeks, little or no learning in the third and fourth weeks, and some learning in the fifth week, when the groups changed practice conditions. The flash card and microcomputer conditions produced equivalent learning.

The research objective is to analyze the effect of game means on the dynamics of strength development in the second-, third- and fourth-grade girls.Materials and methods: the participants in the study were 104 schoolgirls: 32 – second-graders, 32 – third-graders, and 40 – fourth-graders. To achieve the tasks set, the research used the following methods: theoretical analysis and summary of scientific and methodological literature, method of control testing, pedagogical experiment, methods of mathematical statistics.Results: the results of the analysis of variance in correlating the data indicate to what degree various game modes influence the development of strength abilities in the second-, third- and fourth-grade girls. The study observed the strongest effect of the factor in the second-grade girls in the second group – 88.7%, fourth group – 90%, sixth group – 85.4%, and eighth group – 76.4%. The third-grade girls demonstrated the strongest effect of the factor in the eighth group – 82.7%. The fourth-grade girls showed the strongest effect of the motion mode in the sixth group – 74.8% and in the eighth group – 69.7%.Conclusions: It is advisory to use small loads and bodyweight exercises when developing strength abilities in junior girls. Games are performed at a quick and moderate pace. Games should be diverse to involve different muscle groups. The number of games can vary from four to eight depending on the level of physical development and physical preparedness of the schoolers.

This study compared a new method for acquisition of spelling with a traditional method over 9 wk. for 181 third and 188 fourth graders. The covariates were pre-spelling, post-mathematics, and post-reading scores. Analysis of covariance showed statistically significant improvement in the raw scores on the Comprehensive Test of Basic Skills for the fourth graders but not for the third graders.
