An international comparison using a diagnostic testing model: Turkish students’ profile of mathematical skills on TIMSS-R 总被引:2,自引:0,他引:2
This study illustrates how a diagnostic testing model can be used to make detailed comparisons between student populations
participating in international assessments. The performance of Turkish students on the TIMSS-R mathematics test was reanalyzed
with a diagnostic testing model called the Rule Space Model. First, mathematical and cognitive skills (‘attributes’) measured
by the test were determined. One hundred sixty-two items were coded in terms of their attribute involvement, creating an incidence
matrix—the Q-matrix. Using the Q-matrix and the student response data, each student’s attribute mastery profile was determined.
Mean attribute mastery levels of Turkish students were computed and compared to those of their American peers. It was shown
that Turkish students were weak in algebra and probability/statistics. They also demonstrated poor profiles in skills such
as applying rules in algebra, approximation/estimation, solving open-ended problems, recognizing patterns and relationships,
and quantitative reading.

This study investigates the antecedents and consequences of team learning, which is composed of information acquisition, dissemination, and implementation, in information technology (IT) implementation projects. By investigating 129 IT implementation project teams, we found that (1) information acquisition and information dissemination have a positive impact on project outcomes, such as speed-to-users, lower implementation cost, and operational effectiveness, and (2) team behavior and enabler variables, such as teamwork, team communication, interpersonal trust between team members, team commitment, and senior manager support, positively influence team learning. We also found that team anxiety moderates the relationship between team learning and project outcomes. 相似文献

This study examined the role of adolescent perceptions of parental behavior and disrupted parenting in the continuity of antisocial behavior across generations. Participants included 430 adolescents and their biological parents assessed during the period from the 9th to 12th grades (9th grade age in years: M=15.09, SD=0.43). Structural equation modeling provided support for the mediating role of adolescent perceptions and disrupted parenting in the familial transmission of antisocial behavior. Furthermore, the results were consistent across parent and adolescent gender. The findings extend previous research by suggesting a significant role for adolescent perceptions of parents' activities in the development and growth of antisocial behavior. Results also support significant stability in antisocial tendencies over the course of adolescence. 相似文献

Including the perspectives of scientists about the nature and process of science is important for an authentic and nuanced portrayal of science in science education. The small number of studies that have explored scientists’ worldviews about science has thus far generated contradictory findings, with recent studies claiming that scientists simultaneously hold contradictory sophisticated and naïve views. This article reports on an exploratory study that uses the framework of Bhaskar’s critical realism to elicit and separately analyse academic scientists’ ontological and epistemological views about science in semi-structured interviews. When the views of scientists are analysed through the lens of critical realism, it is clear that it is possible to hold a realist ontological commitment about what knowledge is of, simultaneously with a fallibilist epistemological commitment about knowledge itself. The apparent incongruence of scientists’ so-called naïve and sophisticated views about science is resolved when analysed using a critical realist framework. Critical realism offers a simple and coherent framework for science educators that avoids many of the problems of positivism and social constructivism by finding a middle ground between them. The three pillars of critical realism: ontological realism, epistemological fallibilism and judgmental rationality help to make sense of how socially constructed scientific knowledge can be anchored in an independent reality. 相似文献

Serum tumor markers may be requested inappropriately by clinicians. In this retrospective study, we aimed to investigate the
appropriateness of TM requests in our hospital. Patients in the study were identified from the TM requests for 3 months between
June–August 2004, using the laboratory database. A total of 2249 patients (1351 men, 898 women) were included in the study
and there were 6570 TM requests. The number of requests were 1050 (16%) for Carbohydrate Antigen 19-9, 993 (15.1%) for Cancer
Antigen 125, 941 (14.3%) for Prostate Specific Antigen, 921 (14%) for free PSA, 925 (14.1%) for Cancer Antigen 15-3, 788 (12%)
for Alphafetoprotein, 730 (11.1%) for Carcinoembryonic Antigen and 222 (3.4%) for AFP/Human Chorionic Gonadotrophin. Our findings
support the idea that for the evidence-based use of TM requests the education of clinical staff is required. Clear clinical
guidelines including recommendations about the appropriate use of TM can be useful for this education process. Careful audit
studies are also useful to determine the impact of these guidelines on the practice of evidence-based laboratory medicine. 相似文献

Hands‐on learning is a proven method of improving students’ critical thinking skills. Undergraduate research projects are encouraged to help students develop research and laboratory skills. If properly designed and implemented, research opportunities can be embedded in existing student coursework, which increases the number of students who can participate in these research opportunities. Objectives of this study were twofold: (a) to determine students’ perceptions of an undergraduate research laboratory exercise and (b) provide an innovative laboratory exercise for instructors to implement in their own classrooms. Rolled cookies were prepared by a food science class according to American Association of Cereal Chemists Method 10–50.05, using sucrose and alternative sweeteners and evaluated for physicochemical and organoleptic attributes. After completing the exercise, students evaluated cookie physical/organoleptic properties using a hedonic scale, were asked about personal demographics, and were surveyed about research/writing skills and food processing knowledge using a Likert scale. Approximately 50% of the class responded to the 2018 survey and nearly 85% responded to the 2019 survey. On average, 81.6% of students responded with “Strongly Agree” or “Somewhat Agree” to all survey questions, including data collection and analysis, critical thinking skills, experimental design, and replications. Students responded that detailed instructions provided by instructors were beneficial to their ability to understand experimental design, scientific communication, and the importance of using scientific resources. 相似文献

Although understandings of scientific inquiry (as opposed to conducting inquiry) are included in science education reform documents around the world, little is known about what students have learned about inquiry during their elementary school years. This is partially due to the lack of any assessment instrument to measure understandings about scientific inquiry. However, a valid and reliable assessment has recently been developed and published, Views About Scientific Inquiry (VASI; Lederman et al. [2014], Journal of Research in Science Teaching, 51, 65–83). The purpose of this large-scale international project was to collect the first baseline data on what beginning middle school students have learned about scientific inquiry during their elementary school years. Eighteen countries/regions spanning six continents including 2,634 students participated in the study. The participating countries/regions were: Australia, Brazil, Chile, Egypt, England, Finland, France, Germany, Israel, Mainland China, New Zealand, Nigeria, South Africa, Spain, Sweden, Taiwan, Turkey, and the United States. In many countries, science is not formally taught until middle school, which is the rationale for choosing seventh grade students for this investigation. This baseline data will simultaneously provide information on what, if anything, students learn about inquiry in elementary school, as well as their beginning knowledge as they enter secondary school. It is important to note that collecting data from all of the approximately 200 countries globally was not humanly possible, and it was also not possible to collect data from every region of each country. The results overwhelmingly show that students around the world at the beginning of grade seven have very little understandings about scientific inquiry. Some countries do show reasonable understandings in certain aspects but the overall picture of understandings of scientific inquiry is not what is hoped for after completing 6 years of elementary education in any country. 相似文献
