医学生综合素质评价的科学性思考

对医学生综合素质的评价应建立发展性评价观,要充分体现六个统一:评价指标体系做到职业需要和社会发展相统一;评价功能做到全面性和发展性相统一;评价标准要做到综合化和个性化相统一;评价过程要做到结果与过程相统一;评价方法做到量化评价与质性评价相统一;评价主体要做到外部评价和内部评价相统一.使素质教育评价科学化,能真正促进医学生素质的全面发展,培养出合格的适合社会需要的医学人才.     

幼儿加减法运算中的策略发展特点

本研究随机选取北京市三所普通幼儿园小、中、大班儿童共90名,采用实物操作的非言语任务,考察3-5岁幼儿在加减法运算中的策略发展特点。结果表明:随着年龄的增长,儿童使用的策略由模仿、交换向内化、相反数策略转化;3、4岁幼儿在相反数题中,更多使用模仿和交换策略,而5岁幼儿更多使用模仿、相反数策略;在标准型题中,儿童一般较多使用模仿和内化策略;最大表征对儿童策略选择存在影响。     

初中生数学焦虑的调查及其调控研究

数学焦虑既是心理科学研究的对象,又与教育、教学,特别是学科教学密切相关。本文调查发现:部分初中生存在过度的数学焦虑,并且在年级、性别等维度上具有明显差异;教师的评价方式、课堂气氛、数学考试是形成数学焦虑的主要原因。运用三条教学策略的实验研究表明,数学焦虑是可以调控的,而且数学焦虑的缓解对学生数学成绩的提高有一定的促进作用。     

Inter- and intra-individual variability in the kinematics of the back squat

The purpose of this study was to explore the level of inter- and intra-individual variability in the kinematic profiles of the back squat movement among skilled weightlifters. Ten competitive weightlifters volunteered for participation in this study. Barbell velocity (V_Barbell) and angular velocity of the ankle (ω_Ankle), knee (ω_Knee) and hip joint (ω_Hip) were obtained by kinematic recording of six trials at 90% of 1RM in the back squat. Inter-individual variability was assessed by analysing inter-individual differences in the velocity curves through the statistical parametric mapping method. Intra-individual variability was assessed through a correlation analysis between the barbell velocity curves of each trial for each participant. Partial least squares regression analysis, was performed to relate changes in intra-individual variability to movement and anthropometric characteristics. Significant inter- and intra-individual differences were identified in V_Barbell, ω_Ankle, ω_Knee, and ω_Hip (p ≤ 0.05). Having a short trunk and thigh, and a long shin in combination with greater anterior-posterior displacement of the barbell and slower velocities during the acceleration phase increased intra-individual movement consistency over movement variability. The results of the present study clearly demonstrate that skilled weightlifters display both significant inter- and intra-individual variability in the successful execution of the back squat.     

Factors that impact the sociocultural adjustment and well-being of Syrian refugees in Stuttgart – Germany

This study investigated the impact of age, gender, language and acculturation choice on the sociocultural adjustment and well-being of Syrian refugees in Stuttgart, Germany. A total of 214 Syrian refugees participated in this study by filling a demographics questionnaire, the Acculturation Attitudes Scale (AAS-16), the Revised Sociocultural Adjustment Scale (R-SCAS), and the Mental Health Inventory (MHI-18). The results showed that the level of German language acquisition significantly correlated with sociocultural adjustment. No significant correlation was found between age and depression level and no significant difference in depression scores were found as a function of gender. Integration significantly correlated with sociocultural adjustment and mental health. Assimilation correlated significantly with sociocultural adjustment, and separation correlated negatively with mental health.     

Do people make decisions under risk based on ignorance? An empirical test of the priority heuristic against cumulative prospect theory

Brandstätter, Gigerenzer, and Hertwig [Brandstätter, E., Gigerenzer, G., & Hertwig, R. (2006). The Priority Heuristic: Making choices without trade-offs. Psychological Review, 113(2), 409–432] put forward the priority heuristic (PH) as a fast and frugal heuristic for decisions under risk. According to the PH, individuals do not make trade-offs between gains and probabilities, as proposed by expected utility models such as cumulative prospect theory (CPT), but use information in a non-compensatory manner and ignore information. We conducted three studies to test the PH empirically by analyzing individual choice patterns, decision times and information search parameters in diagnostic decision tasks. Results on all three dependent variables conflict with the predictions of the PH and can be better explained by the CPT. The predictive accuracy of the PH was high for decision tasks in which the predictions align with the predictions of the CPT but very low for decision tasks in which this was not the case. The findings indicate that earlier results supporting the PH might have been caused by the selection of decision tasks that were not diagnostic for the PH as compared to CPT.     

Counterintuitive and alternative moves choice in the Water Jug task

MOVE problems, like the Tower of London (TOL) or the Water Jug (WJ) task, are planning tasks that appear structurally similar and are assumed to involve similar cognitive processes. Carder et al. [Carder, H.P., Handley, S.J., & Perfect, T.J. ( 2004). Deconstructing the Tower of London: Alternative moves and conflict resolution as predictors of task performance. The Quarterly Journal of Experimental Psychology 57a, 8, 1459-1483] showed that one predictor of TOL performance was the number of alternative move choices there were at a given point in the solution. In two experiments an individual move experienced on the WJ task was manipulated (perceptually consistent/counterintuitive) along with the number of alternative moves there were to choose between. A verification paradigm was employed in which participants made speeded judgements about the correctness of a move. Results showed performance was consistent with the application of a perceptual strategy accompanied by a process involving the evaluation of non-redundant alternative moves. These are discussed in the context of recent research that has examined the impact of executive dysfunction on Water Jug performance [Colvin, M.K., Dunbar, K., & Grafman, J. (2001). The effects of frontal lobe lesions on goal achievement in the Water Jug task. Journal of Cognitive Neuroscience, 13, 1129-1147].
