PERCEIVED SOCIAL RELATIONSHIPS AND SCIENCE LEARNING OUTCOMES FOR TAIWANESE EIGHTH GRADERS: STRUCTURAL EQUATION MODELING WITH A COMPLEX SAMPLING CONSIDERATION

Based on the Trends in International Mathematics and Science Study 2007 study and a follow-up national survey, data for 3,901 Taiwanese grade 8 students were analyzed using structural equation modeling to confirm a social-relation-based affection-driven model (SRAM). SRAM hypothesized relationships among students’ perceived social relationships in science class and affective and cognitive learning outcomes to be examined. Furthermore, the path coefficients of SRAM for high- and low-achieving subgroups were compared. Given the 2-stage stratified clustering design for sampling, jackknife replications were conducted to estimate the sampling errors for all coefficients in SRAM. Results suggested that both perceived teacher–student relationships (PTSR) and perceived peer relationships (PPR) exert significant positive effects on students’ self-confidence in learning science (SCS) and on their positive attitude toward science (PATS). These affective learning outcomes (SCS and PATS) were found to play a significant role in mediating the perceived social relationships (PTSR and PPR) and science achievement. Further results regarding the differences in SRAM model fit between high- and low-achieving students are discussed, as are the educational and methodological implications of this study.     

The impact of alternative approaches to comforting,closeness of relationship,and gender on multiple measures of effectiveness

The impact of 6 approaches to comforting (suggesting a diversion, expressing optimism, providing an external account, offering assistance, explaining the perspective of the offender, and a combination of the first 5), attributed to either a good friend or a casual acquaintance, was assessed for 2 situations by 394 students. Distressed individuals responded to comforting messages along two dimension: feeling less upset and feeling demeaned, with some indications that yet a third dimension (appreciating the concern of the comforter) may exist. The message that combined elements from the other 5 approaches yielded generally the most positive responses, but responses to specific message approaches varied with situation and dimension of response. Messages from good friends were more successful than those from casual acquaintances in helping the distressed individual to feel less upset.

A comparison study of augmented reality versus interactive simulation technology to support student learning of a socio-scientific issue

We investigated the impact of an augmented reality (AR) versus interactive simulation (IS) activity incorporated in a computer learning environment to facilitate students' learning of a socio-scientific issue (SSI) on nuclear power plants and radiation pollution. We employed a quasi-experimental research design. Two classes (a total of 45 ninth-grade students) were randomly assigned to either the AR or IS treatments. We compared three outcome variables of the AR and IS groups: knowledge of and attitude towards the SSI, and perceptions of the AR or IS feature. We also examined the interplay among the three variables within each of the two groups. The results indicated no significant differences in knowledge and attitude, but a significant difference in the perceptions between the two groups. Moreover, different patterns of correlations among the variables were identified. The implication includes educational impact of emerging AR technologies to support affective aspects of student learning of SSIs.     

Students’ development of socio-scientific reasoning in a mobile augmented reality learning environment

In this study we investigated how a newly developed learning environment that integrates mobile augmented reality (AR) technology supported students’ socio-scientific reasoning (SSR). Drawing upon the reasoned action theory, we consider the roles of students’ attitudes toward SSR before learning, and their cognitive and emotional engagement during learning in the students’ actual performance of SSR. The implementation results indicate the impact of the learning environment on students’ scientific knowledge and attitude change. Moreover, we identified a significant path of how the students developed their SSR by the interactions among their attitude toward SSR, and their cognitive and emotional engagement in the mobile AR learning environment. On the other hand, the students’ post-learning attitudes toward SSR were dominated by their pre-learning attitudes. Implications and suggestions are discussed.     

毛叶石楠种群蜡叶材料的定量分析

 Taxa of the Photinia villosa complex, including P. villosa, its var. sinica, and P. parvifolia, are taxonomically perplexing. By means of conventional taxonomic methods, it is difficult to discriminate them from one another. Basing upon herbarium materials of about 100 sheets of specimens collected from seven provinces in China, a quantitative analysis of the correlations between certain key characters was then used to reexamine the validity of the above taxa.  Results from both pictorialized scatter diagram  and histogram have indicated that the complex could be divided into the following parts: (1) I(V)—characterized by many (7-32)-flowered corymbs and prominent pubes- cence at least when young, agreed with typical Photinia villosa; (2) II(S)—with less (2-12)-flowered corymbs (sometimes with umbels on the same herbarium sheet) and leaves usually pubescent along the midrib on the lower side, agreed well with P. villosa var. sinica; (3)III(P)—with few (1-9)-flowered  umbels  and  plant  glabrous throughout, agreed with P. parvifolia, but apparently overlaped with the lower portion of II(S);  (4) IV(T)—characterized by umbels with  still  fewer  [1-2(-5)] flowers, especially long, slenderer and pendulous pedicels and plant totally glabrous, was undoubtedly a new form.  Both diagrams also showed that these four parts are so closely related to one another that they are by no means strictly separable. Thus it is better to treat them all as varieties of the said complex. A proper taxonomic treatment should include the reduction of Photinia parvifolia to a varietal rank of P. villosa as well as an addition of the newly discovered variety P. villosa var. tenuipes as presentedin this paper.     

Primary tuberculous infection of breast： experiences of surgical resection for aged patients and review of literature

Primary mammary tuberculosis is a rare entity that usually occurs in female of reproductive age. Herein three such patients including two males with ages over 80 years, who underwent surgical resection, are reported. Fine needle biopsy failed to achieve specific diagnosis before surgical operation. All of their conditions got satisfactory improvement and anti-tuberculosis chemotherapy was administered postoperatively. Previous literature related to the epidemiology, diagnosis and treatment for mammary tuberculosis will be also reviewed. Mammary tuberculosis is usually related to breast feeding women and is extremely rare in aged man. The possible mechanisms resulting in this disease in our three patients, including direct extension, reactivation, or transmitted by staffs or peers of the nursing home, would also be discussed.     

Facilitating Preschoolers’ Scientific Knowledge Construction via Computer Games Regarding Light and Shadow: The Effect of the Prediction-Observation-Explanation (POE) Strategy

Educational researchers have suggested that computer games have a profound influence on students’ motivation, knowledge construction, and learning performance, but little empirical research has targeted preschoolers. Thus, the purpose of the present study was to investigate the effects of implementing a computer game that integrates the prediction-observation-explanation (POE) strategy (White and Gunstone in Probing understanding. Routledge, New York, 1992) on facilitating preschoolers’ acquisition of scientific concepts regarding light and shadow. The children’s alternative conceptions were explored as well. Fifty participants were randomly assigned into either an experimental group that played a computer game integrating the POE model or a control group that played a non-POE computer game. By assessing the students’ conceptual understanding through interviews, this study revealed that the students in the experimental group significantly outperformed their counterparts in the concepts regarding “shadow formation in daylight” and “shadow orientation.” However, children in both groups, after playing the games, still expressed some alternative conceptions such as “Shadows always appear behind a person” and “Shadows should be on the same side as the sun.”
