The Present study aims at Finding out the (The effect Buxton Model in acquiring Geographical Concepts and Retaining them for Second intermediate class students ).    A partial control experimental design with post test experimental control groups, The sample is deliberately selected from first AL-Rusafah Directorate General of Education in Baghdad.    Intermediate school AL.khulfau AL.Rashedeen for boys is the assigned school for  the experimental work. Two sections are randomly selected from the lst stage(B)is assigned as the experimental group where while (C)is assigned at the control group,.   The total number of sample (67) male students distributed into (33) students in the experimental group and(34) students in the control group .    The two groups are equalized in the following variables ; prior knowledge ,age , IQ, ,students scores in Geography on the previous academic year . Several external factors are controlled during the experiment.           The teaching material is specified in three chapters selected from the prescribed textbook for the Second intermediate stage which is entitled for the academic year 2013 -2014 in Iraq Content analysis is done to identify the major and miner concepts which totaled (97) concepts .In the light of the concepts, behavioral objectives are formulated totaling(51) ones based on Blooms taxonomy on the following levels ;identifying, recognizing , applying.(40)lesson plans are prepared ,20 per group. and prepared test for acquiring geography concepts including (50) Test items, after three months ,at the end of the experimental work. T-test formula for two independent samples is used to process data and find out results . show the following; There are statistically significant difference on a level of significance of (0,05) in acquiring geography concepts between the two groups in favour of the experimental group. There are statistically significant difference on a level of significance of (0,05) in retaining geography concepts between the two groups in favour of the experimental group.

To better prepare the professionals and scholars of tomorrow in the field of communication sciences and disorders (CSD), a research project in which undergraduate students collected and analyzed language samples of child-parent dyads is presented. Student researchers gained broad and discipline-specific inquiry skills related to the ethical conduct of research, the literature review process, data collection using language assessment techniques, language sample analysis, and research dissemination. Undergraduate students majoring in CSD developed clinical research knowledge, skills, and dispositions necessary for future graduate level study and professional employment. In addition to the benefits of student growth and development, language samples collected through this project are helping to answer research questions regarding communicative turn-taking opportunities within the everyday routines of young children, the effects of turn-taking interactions on language development, and the construct validity of language sampling analysis techniques.

Problem Solving Task

This study compared individuals with pairs in a scientific problem-solving task. Participants interacted with a virtual psychological laboratory called Virtue to reason about a visual search theory. To this end, they created hypotheses, designed experiments, and analyzed and interpreted the results of their experiments in order to discover which of five possible factors affected the visual search process. Before and after their interaction with Virtue, participants took a test measuring theoretical and methodological knowledge. In addition, process data reflecting participants’ experimental activities and verbal data were collected. The results showed a significant but equal increase in knowledge for both groups. We found differences between individuals and pairs in the evaluation of hypotheses in the process data, and in descriptive and explanatory statements in the verbal data. Interacting with Virtue helped all students improve their domain-specific and domain-general psychological knowledge.

Induced Forgetting

Retrieval-induced forgetting (RIF) refers to the finding that the retrieval of an item from memory impairs the retrieval of related items. The extent to which this impairment is found in laboratory tests varies between individuals, and recent studies have reported an association between individual differences in the strength of the RIF effect and other cognitive and clinical factors. The present study investigated the reliability of these individual differences in the RIF effect. A RIF task was administered to the same individuals on two occasions (sessions T1 and T2), one week apart. For Experiments 1 and 2 the final retrieval test at each session made use of a category-cue procedure, whereas Experiment 3 employed category-plus-letter cues, and Experiment 4 used a recognition test. In Experiment 2 the same test items that were studied, practiced, and tested at T1 were also studied, practiced, and tested at T2, but for the remaining three experiments two different item sets were used at T1 and T2. A significant RIF effect was found in all four experiments. A significant correlation was found between RIF scores at T1 and T2 in Experiment 2, but for the other three experiments the correlations between RIF scores at T1 and T2 failed to reach significance. This study therefore failed to find clear evidence for reliable individual differences in RIF performance, except where the same test materials were used for both test sessions. These findings have important implications for studies involving individual differences in RIF performance.
