This study was based on the framework of the “conflict map” to facilitate student conceptual learning about causes of the seasons. Instruction guided by the conflict map emphasizes not only the use of discrepant events, but also the resolution of conflict between students' alternative conceptions and scientific conceptions, using critical events or explanations and relevant perceptions and conceptions that explicate the scientific conceptions. Two ninth grade science classes in Taiwan participated in this quasi‐experimental study in which one class was assigned to a traditional teaching group and the other class was assigned to a conflict map instruction treatment. Students' ideas were gathered through three interviews: the first was conducted 1 week after the instruction; the second 2 months afterward; and the third at 8 months after the treatment. Through an analysis of students' interview responses, it was revealed that many students, even after instruction, had a common alternative conception that seasons were determined by the earth's distance to the sun. However, the instruction guided by the framework of the conflict map was shown to be a potential way of changing the alternative conception and acquiring scientific understandings, especially in light of long‐term observations. A detailed analysis of students' ideas across the interviews also strongly suggests that researchers as well as practicing teachers need to pay particular attention to those students who can simply recall the scientific fact without deep thinking, as these students may learn science through rote memorization and soon regress to alternative conceptions after science instruction. © 2005 Wiley Periodicals, Inc.

Neuroanatomical localization (NL) is a key skill in neurology, but learners often have difficulty with it. This study aims to evaluate a concise NL tool (NLT) developed to help teach and learn NL. To evaluate the NLT, an extended‐matching questions (EMQ) test to assess NL was designed and validated. The EMQ was validated with fourth‐year medical students and internal medicine and neurology residents. The NLT's usability was evaluated with third‐ and fourth‐year students, and the effectiveness was evaluated with an experimental study of second‐year students, using the EMQ as the outcome measure. Students were taught how to use both the NLT and textbook algorithms (control) to perform NL, then randomized into either group, and only allowed to use their assigned tool to complete the EMQ. Primary outcome was the difference in mean EMQ scores expressed as a percentage of total score. For EMQ validation, students (n = 56) scored lower than residents (n = 50) (76.7% ± 1.7 vs. 83.0% ± 1.6; mean ± standard error of mean, P < 0.009). The EMQ demonstrated good reliability (Cronbach's α 0.85) and generalizability (G‐coefficient 0.85). Third‐ (n = 77) and fourth‐year (n = 42) students found the NLT user‐friendly and helpful in their learning of NL. In the experimental study, scores were significantly higher for NLT group (n = 94) than for controls (n = 101) (42.5 vs. 37.0%, P = 0.014); the effect size (Cohen's d) was 0.36. The EMQ is validated to reliably assess NL and is generalizable, feasible, practical, and of low cost. The concise and user‐friendly NLT for NL was effective in aiding medical student performance of NL. Anat Sci Educ 11: 262–269. © 2017 American Association of Anatomists. 相似文献

This study explored the effects of arguing to learn in a socioscientific context on the fundamental and derived components of reading, writing, and science understanding as integral parts of science literacy. We adopted mixed-methods in which the 1-group pretest–posttest design with supplemental interviews and questionnaires. The pretest evaluated the dependent variables (reading and writing scores), the treatment was arguing to learn about the global climate change issue, the posttest evaluated the dependent variables, and follow-up questionnaires and interviews informed the quantitative results. An intact grade six class (N = 28) at an urban elementary school located in central Taiwan was the participants. Analyses of the pretest–posttest gain scores and correlations between these outcomes revealed significant (p < 0.05) improvements in writing and associations among reading, writing, and arguing to learn. Interpretation of the qualitative data (interview and questionnaire responses) supported that argumentation as an instructional treatment focused on fundamental literacy could play a positive role in facilitating students’ enhanced science understanding (derived literacy). 相似文献

This quantitative-qualitative study seeks to determine the effectiveness of TIMS (Thomasian Interactive Multimedia Software)
in teaching the introductory topics in Trigonometry. The acceptability of the software to the student respondents was established
using the content, design, interface, and effectiveness of the media used as the evaluation criteria. The critical trial use
of the software involving a small group of students was employed to elicit the needed information. It aims to provide meaningful
report which includes the strengths and weaknesses of the software, the recurring problems, and constraints during its implementation,
and a critique of the software as to how it should be improved for future use. 相似文献

Educators aim to equip students with learning strategies they can apply when approaching new problems on their own. Teaching design-thinking strategies may support this goal. A first test would show that the strategies are good for learning and that students spontaneously transfer them beyond classroom instruction. To examine this, we introduce choice-based assessments (CBAs). CBAs measure how people learn when there is minimal guidance and they must make decisions as independent learners. Here, sixth-grade students completed multiple design activities that emphasized either seeking constructive criticism or exploring a space of alternatives. Afterward, they completed the CBAs, which measured strategy transfer. Results showed that lower-achieving students benefitted most from instruction, exhibiting a relative increase in their use of design-thinking strategies. In addition, strategy choices correlated with prior achievement measures and appeared to mediate performance in and learning from the CBAs. The choices to use the two strategies themselves were not correlated, which indicates that they are not subsets of a larger construct, such as growth mindset. In sum, CBAs enabled a double demonstration: design-thinking strategies may improve learning and problem solving, and design-thinking instruction may improve the likelihood of lower-achieving students choosing to use effective strategies in novel settings that require new learning. 相似文献

A major goal of contemporary education is to teach students how to learn on their own. Assessments have largely lagged behind this goal, because they measure what students have learned and not necessarily their learning processes. This research presents Posterlet, an assessment that collects evidence regarding the strategies that students choose while learning on their own. Posterlet is an educational game-based assessment that measures two design thinking choices: students’ choices to seek critical (ie, negative) feedback and to revise their work while they learn graphic design principles through creating posters. This research also presents an examination of students’ choices to seek feedback and to revise, as well as of students’ learning outcomes based on these choices. This game-based assessment approach is empirically validated with three research studies sampling nearly 300 middle-school and college students who played Posterlet and completed a posttest. Results show that the game helps students learn, as students who play the game before completing the posttest learn more graphic design principles than students who only complete the posttest. Moreover, the choices to seek critical feedback and to revise can predict learning and can be used as valid outcome measures for learning. Findings can be used in developing and evaluating models of instruction and assessment that may help students make informed learning choices. A discussion of present and future trends in theory regarding digital feedback environments is also included. 相似文献

The purpose of this study was to develop a questionnaire that measures students' motivation toward science learning (SMTSL). Six scales were developed: self‐efficacy, active learning strategies, science learning value, performance goal, achievement goal, and learning environment stimulation. In total, 1407 junior high school students from central Taiwan, varying in grades, sex, and achievements, were selected by stratified random sampling to respond to the questionnaire. The Cronbach alpha for the entire questionnaire was 0.89; for each scale, alpha ranged from 0.70 to 0.89. There were significant correlations (p?<?0.01) of the SMTSL questionnaire with students' science attitudes (r?=?0.41), and with the science achievement test in previous and current semesters (r p?=?0.40 and r c?=?0.41). High motivators and low motivators showed a significant difference (p?<?0.01) on their SMTSL scores. Findings of the study confirmed the validity and reliability of the SMTSL questionnaire. Implications for using the SMTSL questionnaire in research and in class are discussed in the paper. 相似文献
