Integrating direct and inquiry-based instruction in the teaching of critical thinking: an intervention study     

Kelly Y. L. Ku  Irene T. Ho  Kit-Tai Hau  Eva C. M. Lai 《Instructional Science》2014,42(2):251-269

Critical thinking is a unifying goal of modern education. While past research has mostly examined the efficacy of a single instructional approach to teaching critical thinking, recent literature has begun discussing mixed teaching approaches. The present study examines three modes of instruction, featuring the direct instruction approach and the inquiry-based approach in different sequences and proportions, in enhancing Chinese secondary student’s critical thinking performance. A total of 651 Grade 12 students participated in an 18-hour intervention with pre- and post-intervention measures on critical thinking performance and critical thinking dispositions. Specifically, critical thinking assessments utilizing different response format were used. Those who received training showed greater improvement on at least one of the critical thinking assessments compared to those who received no training. Participants’ performances with regards to different critical thinking assessments are discussed. Benefits of adopting more than one instructional approach to teaching critical thinking are highlighted.  相似文献

Student performance and attitudes using personalized mathematics instruction     

Heng-Yu Ku  Howard J. Sullivan 《Educational technology research and development : ETR & D》2002,50(1):21-34

This study investigated the effects of personalized instruction on the achievement and attitudes of Taiwanese students on two-step mathematics word problems. A total of 136 fourth-graders in a Taiwanese public school participated in the study. Subjects initially completed a Student Survey on which they chose their favorite foods, sports, stores, classmates, and other selections. The most popular items were then used to create personalized math word problems for the pretest, personalized instructional program, and posttest. Subjects were blocked by ability based on their pretest scores and were randomly assigned within ability levels to either a personalized or nonpersonalized version of the print-based instructional program. After finishing the program, subjects completed a student attitude survey and the posttest. A repeated-measures univariate analysis of variance revealed that subjects in the personalized treatment made significantly greater pretest-to-posttest gains than those in the nonpersonalized treatment. Subjects also performed significantly better on the personalized pretest and posttest problems than on the nonpersonalized problems. Personalized subjects and higher-ability students both had significantly more positive attitudes toward the instructional program than did their nonpersonalized and lower-ability counterparts. This research was conducted while he was a doctoral student at Arizona State University.  相似文献

Printing strategies for scaling-up perovskite solar cells     

Yulong Wang  Changyu Duan  Pin Lv  Zhiliang Ku  Jianfeng Lu  Fuzhi Huang  Yi-Bing Cheng 《国家科学评论(英文版)》2021,8(8)

Photovoltaic technology offers a sustainable solution to the problem of soaring global energy demands. Recently, metal halide perovskite solar cells (PSCs) have attracted worldwide interest because of their high power conversion efficiency of 25.5% and great potential in becoming a disruptive technology in the photovoltaic industry. The transition from research to commercialization requires advancements of scalable deposition methods for both perovskite and charge transporting thin films. Herein, we share our view regarding the current challenges to fabrication of PSCs by printing techniques. We focus particularly on ink technologies, and summarize the strategies for printing uniform, pinhole-free perovskite films with good crystallinity. Moreover, the stability of perovskite solar modules is discussed and analyzed. We believe this review will be advantageous in the area of printable electronic devices.  相似文献
