Halogen bonding in the co-crystallization of potentially ditopic diiodotetrafluorobenzene: a powerful tool for constructing multicomponent supramolecular assemblies

Halogen bonding is emerging as a significant driving force for supramolecular self-assembly and has aroused great interest during the last two decades. Among the various halogen-bonding donors, we take notice of the ability of 1,4-diiodotetrafluorobenzene (1,4-DITFB) to co-crystallize with diverse halogen-bonding acceptors in the range from neutral Lewis bases (nitrogen-containing compounds, N-oxides, chalcogenides, aromatic hydrocarbons and organometallic complexes) to anions (halide ions, thio/selenocyanate ions and tetrahedral oxyanions), leading to a great variety of supramolecular architectures such as discrete assemblies, 1D infinite chains and 2D/3D networks. Some of them act as promising functional materials (e.g. fluorescence, phosphorescence, optical waveguide, laser, non-linear optics, dielectric and magnetism) and soft materials (e.g. liquid crystal and supramolecular gel). Here we focus on the supramolecular structures of multicomponent complexes and their related physicochemical properties, highlight representative examples and show clearly the main directions that remain to be developed and improved in this area. From the point of view of crystal engineering and supramolecular chemistry, the complexes summarized here should give helpful information for further design and investigation of the elusive category of halogen-bonding supramolecular functional materials.     

近代中国民族精神重构中的经验之思与形上之思

近代中国面临双重危机:秩序危机与意义危机。双重危机唤起改造国民素质和重构民族精神的时代主题。在这一过程中,近代知识分子一方面将西方的自由、民主、科学等经验之思提升为形上之思以应对双重危机。另一方面立足于传统儒家伦理精神,从儒家的形上之思中开掘出现代科学与民主的经验之思,以此解决民族危机。因此,经验之思与形上之思成为近代中国国民素质改造和民族精神重塑的重要内容,并且在当代中国的现代化发展和民族精神重构过程中发挥了重要作用。     

Measuring Knowledge Integration Learning of Energy Topics: A two-year longitudinal study

Although researchers call for inquiry learning in science, science assessments rarely capture the impact of inquiry instruction. This paper reports on the development and validation of assessments designed to measure middle-school students’ progress in gaining integrated understanding of energy while studying an inquiry-oriented curriculum. The assessment development was guided by the knowledge integration framework. Over 2 years of implementation, more than 4,000 students from 4 schools participated in the study, including a cross-sectional and a longitudinal cohort. Results from item response modeling analyses revealed that: (a) the assessments demonstrated satisfactory psychometric properties in terms of reliability and validity; (b) both the cross-sectional and longitudinal cohorts made progress on integrating their understanding energy concepts; and (c) among many factors (e.g. gender, grade, school, and home language) associated with students’ science performance, unit implementation was the strongest predictor.     

Investigating the impact of automated feedback on students’ scientific argumentation

ABSTRACT

This study investigates the role of automated scoring and feedback in supporting students’ construction of written scientific arguments while learning about factors that affect climate change in the classroom. The automated scoring and feedback technology was integrated into an online module. Students’ written scientific argumentation occurred when they responded to structured argumentation prompts. After submitting the open-ended responses, students received scores generated by a scoring engine and written feedback associated with the scores in real-time. Using the log data that recorded argumentation scores as well as argument submission and revisions activities, we answer three research questions. First, how students behaved after receiving the feedback; second, whether and how students’ revisions improved their argumentation scores; and third, did item difficulties shift with the availability of the automated feedback. Results showed that the majority of students (77%) made revisions after receiving the feedback, and students with higher initial scores were more likely to revise their responses. Students who revised had significantly higher final scores than those who did not, and each revision was associated with an average increase of 0.55 on the final scores. Analysis on item difficulty shifts showed that written scientific argumentation became easier after students used the automated feedback.

Learning Computer Graphics Using Virtual Reality Technologies Based on Constructivism – Case Study of the WebDeGrator System

This study applies constructivist principles and Virtual Reality (VR) technology to the Web-based Interactive Design Graphics (WebDeGrator) system to improve learning computer graphics. The constructivist treatment provides students with access to their choice of source content, three-dimensional (3D) modeling tools and interactive behaviors in a virtual environment. In this study, we developed a VR-based learning system to simulate and adjust computer graphics through sculpture graphic algorithms in real-time. We will discuss the relationship between constructivism and VR technology and also how the WebDeGrator system encourages student-learning through VR technology.     

The Effects of Motivational Instruction on College Students' Performance on Low-Stakes Assessment

Assessments of student learning outcomes (SLO) have been widely used in higher education for accreditation, accountability, and strategic planning purposes. Although important to institutions, the assessment results typically bear no consequence for individual students. It is important to clarify the relationship between motivation and test performance and identify practical strategies to boost students' motivation in test taking. This study designed an experiment to examine the effectiveness of a motivational instruction. The instruction increased examinees' self-reported test-taking motivation by .89 standard deviations (SDs) and test scores by .63 SDs. Students receiving the instruction spent an average of 14 more seconds on an item than students in the control group. Score difference between experimental and control groups narrowed to .23 SDs after unmotivated students identified by low response time were removed from the analyses. The findings provide important implications for higher education institutions which administer SLO assessments in a low-stakes setting.
