小学生数学学习策略的运用与发展特点

考察小学生学习策略运用的状况与发展特点是对小学生进行有效策略指导的前提。本研究采用自编的有较高信、效度的《小学生效学学习策略》量表,对658名小学生进行测查,结果表明：小学生的数学元认知策略和认知策略的使用都约高于“一半符合”的3分临界值之上．小学生的元认知策略的发展高于认知策略．小学生的元认知与认知策略有非常显著的高相关;学校是影响小学生学习策略发展的重要因素,不同学校小学生策略的使用有显著差异,年级、性别对小学生的学习策略的使用无明显影响,本研究支持了小学生的学习策略的发展未随年龄的增长而增长的观点。     

Effect of client-centred therapy on the coping strategies of sexually harassed students in tertiary institutions in Taraba State,Nigeria

This study examined the effects of client-centred therapy (CCT) on the coping strategies of sexually harassed students in tertiary institutions in Taraba State, Nigeria. It also looked for any gender differences in the effect of CCT on the coping strategies of sexually harassed students. We employed a quasi-experimental and pretest–post-test design with control group. The statistical population comprised 250 students who had experienced sexual harassment in tertiary institutions, of which 20 students were selected using convenience sampling. The students who had been sexually harassed were then randomly assigned to the experimental and control groups. The experimental group subsequently underwent six 60-min sessions of CCT, while the control group received placebo treatment on drug abuse. The research tools included a sexual harassment battery (SHB). Inferential statistics of analysis of covariance (ANCOVA) was used to analyse the data. Cronbach's alpha produced a reliability coefficient of 0.79 for the SHB. The following findings were recorded: (i) client-centred therapy effectively increased the coping strategies of students and (ii) there was no significant mean difference between male and female students in the effectiveness of CCT on coping strategies.     

Modelling multiple problem-solving strategies and strategy shift in cognitive diagnosis for growth

Problem-solving strategies, defined as actions people select intentionally to achieve desired objectives, are distinguished from skills that are implemented unintentionally. In education, strategy-oriented instructions that guide students to form problem-solving strategies are found to be more effective for low-achieving students than the skill-oriented instructions designed for enhancing their skill implementation ability. Although the existing longitudinal cognitive diagnosis models (CDMs) can model the change in students' dynamic skill mastery status over time, they are not designed to model the shift in students' problem-solving strategies. This study proposes a longitudinal CDM that considers both between-person multiple strategies and within-person strategy shift. The model, separating the strategy choice process from the skill implementation process, is intended to provide diagnostic information on strategy choice as well as skill mastery status. A simulation study is conducted to evaluate the parameter recovery of the proposed model and investigate the consequences of ignoring the presence of multiple strategies or strategy shift. Further, an empirical data analysis is conducted to illustrate the use of the proposed model to measure strategy shift, growth in skill implementation ability and skill mastery status.     

Sharing food with infants in Hadza communities in Tanzania

By analyzing mealtime interactions of Tanzanian Hadza infants with their interactional partners, we explored how two foundational schemas, namely giving/sharing and autonomy are realized and fostered in infants. We focused on three aspects of the mealtime interactions, namely how the infants’ share was protected, whether independent eating was fostered by the infants’ interactional partners, and how infants were encouraged to share food. To answer these questions, we also considered the settings that were created for infant eating, persons involved, and characteristics of the foods. Hadza infants (N = 24) between the ages of approximately 6 and 27 months were video recorded in mealtime situations. The videos were analyzed qualitatively and revealed the following patterns: First, infants’ shares were protected by eating meals in secluded places or providing infants with separate dishes. Second, independent eating was situational. It can be limited according to the child’s interest in the food or by the interactional partner. Some caregivers subtly enhanced independence by appearing unaware of infants’ signals. Third, sharing was encouraged and supported when it occurred spontaneously. Infants were also asked to share and occasionally tricked into sharing. Tolerated scrounging seemed to be generally accepted by both infants and caregivers. However, we also observed conflicts in competitive situations and somewhat overwhelmed infants. These results are discussed in light of hunter-gatherers’ foundational schemas and livelihood changes observed in the Hadza.     

假设检验思维策略的发展研究

运用自编的一个关于规则发现的计算机程序,研究了小学生、中学生和大学生解决问题过程中的形成假设、设计实验、实验检验三个阶段上的“假设－检验”思维策略。结果发现,小学生的假设检验能力比较低,中学生的水平有了明显的发展,中小学阶段是培养儿童科学发现的假设检验能力的关键期。     

How foreign exchange dealers in the City of London cope with occupational stress

Two hundred and twenty-five foreign exchange dealers working in the City of London completed the Coping Inventory of the Occupational Stress Indicator as part of an investigation of the mental health, job satisfaction, alcohol intake, and occupational stress of this employment group. Results indicate that dealers make less use of the coping strategies examined than the normative population, and that dealers appear to be a very homogeneous group in their use of coping techniques. The coping strategies adopted by various subgroups of dealers were also examined. Problems with the reliability of the Coping Inventory are highlighted.     

Community-based instruction for independent meal preparation by adults with profound mental retardation

Three adults with profound mental retardation and very limited reading skills were transitioned to community living after spending more than 20 years in a residential facility. Community-based instruction was used to teach them to independently prepare meals. Directed rehearsal and prompting procedures were used to teach them those meal preparation skills that they were unable to perform independently. We present assessment, training and followup data on the preparation of a dessert by the three participants. Following an assessment on the steps needed to prepare the dessert, training was introduced in a multiple baseline across subjects design. Results showed that the participants were able to independently prepare the dessert in up to 21 pre-training and training sessions. Monthly followup for six months showed that they were able to independently prepare the dessert in various community settings of their choice.     

A COMPARISON OF TIME DELAY AND DECREASING PROMPT HIERARCHY STRATEGIES IN TEACHING BANKING SKILLS TO STUDENTS WITH MODERATE HANDICAPS

Four students with moderate handicaps were taught to cash checks and to use an automatic teller through either a decreasing prompt hierarchy or time delay procedure. The strategies were compared within a multielement design. Results indicated that both strategies led to the acquisition of the target tasks; however, the decreasing prompt hierarchy was more efficient. Four and 8-week follow-up probes indicated that the strategies were equally effective in producing maintenance of performance.
