The purpose of this study is to explore whether pre-service teacher education in Taiwan equips in-service teachers with the necessary knowledge and competency to meet the demands of the professional career. A questionnaire was developed to investigate such competency disparity. The questionnaire containing 44 items within six categories was distributed to 305 samples in Taiwan. With a return rate of 92.5%, 282 valid samples were returned and analyzed. 相似文献

This study investigated the effects of argument scaffolding and source credibility on science text comprehension. Eighty-seven college students were randomly assigned to an argument scaffolding activity, or no scaffolding, and read 2 science texts, attributed to a high- or a low-credibility source. The argument-scaffolding group recalled less text-based information but generated more knowledge-based inferences than did the no-scaffolding group. High source credibility enhanced readers’ text-based recall but had little effect on knowledge-based inferences or situation models. Overall, results suggest that argumentation facilitates deeper text comprehension and better argument understanding, while at the same time reducing the effect of source credibility on text processing. 相似文献

We present a new normal basis multiplication scheme using a multiplexer-based algorithm. In this algorithm, the proposed multiplier processes in parallel and has a multiplexer-based structure that uses MUX and XOR gates instead of AND and XOR gates. We show that our multiplier for type-1 and type-2 normal bases saves about 8% and 16%, respectively, in space complexity as compared to existing normal basis multipliers. Finally, the proposed architecture has regular and modular configurations and is well suited to VLSI implementations. 相似文献

A large number of studies have compared learning outcomes in fully online courses to those in face-to-face courses. Fewer studies have examined why students choose to enrol in fully online courses to begin with, and no study has yet addressed the question of why some students choose not to register in online courses. This study contributes to scholarly understanding of online education by examining for the first time why students may choose to take a large lecture course face-to-face, when they know that the same course is offered by their institution online in the same semester, for the same credit and at the same tuition cost. Through a survey, 48 students in a face-to-face offering of an introductory Educational Psychology course reported why they chose to attend lectures and tutorials in person when they could have earned the same credit without doing so. A majority of respondents suggested that they believed they would learn better face-to-face, and expressed informal theories about why this would be the case. We examine these informal theories, and the possible implications they may have for future research and institutional planning with regard to online course offerings. 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

This study investigates the effects of argument stance on knowledge inquiry skills. Sixty-two participants were assigned to three argument stance conditions (proponent, opponent, or control) to receive scaffolded argumentation practice on two science issues in random order. After the argumentation treatment, participants were asked to write down their own opinions regarding the claim. Their responses were analysed according to argument structure, argument content, methods of refutation, and number of new propositions. Results revealed that taking a proponent's stance increased the use of evidence in argumentation, while taking an opponent's stance enhanced both the use of evidence and alternative-based refutations to the claim, number of falsifications, and number of new propositions. This implies that arguing from an opponent's stance may increase the search for multiple causes behind observed phenomena and the need for evidence, thereby alleviating the confirmation bias in thinking. 相似文献
