Designing a constructive learning activity with interactive elements: the effects of perspective-shifting and the quality of source material     

Gregor Damnik  Antje Proske  Hermann Körndle 《Interactive Learning Environments》2017,25(5):634-649

When teachers or instructors create computer-based learning environments, they often solely consider technical aspects of interactivity. As a consequence, learners’ main role is to respond to requests of the learning environment (e.g. by answering multiple-choice questions). This aspect of interactivity is, however, not sufficient to understand the complex benefits of interactivity for learners’ knowledge acquisition. In order to create a higher level of interactivity, an instructional task that encourages learners to design learning materials for fellow learners is used in this paper. We will show that this instructional task can induce interactive elements because learners are encouraged to take not only their own perspective into account when designing. In addition, we investigated if the quality of source material affects knowledge acquisition in design tasks. In a two-by-two design, students (n?=?108) had to design either a learning environment for others (i.e. to perform perspective-shifting), or a representation of acquired knowledge for themselves (no perspective-shifting) with less or more coherent information sources. Results indicate that performing perspective-shifting can be a powerful technique for eliciting interactive learning behavior and, thus, for learning. The quality of information sources does not influence knowledge acquisition to a great extent.  相似文献

Metabolic demand and muscle damage induced by eccentric cycling of knee extensor and flexor muscles     

Luis Peñailillo  Nicolás Guzmán  José Cangas  Alvaro Reyes  Hermann Zbinden-Foncea 《European Journal of Sport Science》2017,17(2):179-187

The aim of this study was to examine the metabolic demand and extent of muscle damage of eccentric cycling targeting knee flexor (FLEX) and knee extensor (EXT) muscles. Methods: Eight sedentary men (23.3?±?0.7?y) underwent two eccentric cycling sessions (EXT and FLEX) of 30?min each, at 60% of the maximum power output. Oxygen consumption (VO₂), heart rate (HR) and rated perceived exertion (RPE) were measured during cycling. Countermovement and squat jumps (CMJ and SJ), muscle flexibility, muscle soreness and pain pressure threshold (PPT) of knee extensor and flexor muscles were measured before, immediately after and 1–4 days after cycling. Results: FLEX showed greater VO₂ (+23%), HR (+14%) and RPE (+18%) than EXT. CMJ and SJ performance decreased similarly after cycling. Muscle soreness increased more after EXT than FLEX and PPT decreased in knee extensor muscles after EXT and decreased in knee flexor muscles after FLEX. Greater loss of muscle flexibility in knee flexor muscles after FLEX was observed. Conclusion: Eccentric cycling of knee flexor muscles is metabolically more demanding than that of knee extensors, however muscle damage induced is similar. Knee flexors experienced greater loss of muscle flexibility possibly due to increased muscle stiffness following eccentric contractions.  相似文献   

Possibilities of altering arm and shoulder muscle activation in a static therapeutic climbing exercise through arm position,hand support and wall inclination     

Martin Pühringer  Gerda Strutzenberger  Daniela Leitl  Konrad Holzner  Hermann Schwameder 《European Journal of Sport Science》2017,17(9):1212-1219

The aim of the study was to quantify the activation of arm and shoulder muscles during a static therapeutic climbing exercise and to investigate the possibility of altering the muscle activation through arm position (Jug, Undercling, Sidepull internal rotated, Sidepull external rotated), hand support (one-handed, double-handed) and wall inclination (0°, 12°). Electromyographic (EMG) activity of 14 healthy, climbing unexperienced males for the right m. biceps brachii (BB), m. serratus anterior (SA), m. upper, middle and lower trapezius (UT, MT, LT) showed mainly low to moderate EMG activation levels (BB: 4.1–40.1% maximum voluntary isometric contraction (MVIC), SA: 4.5–24.5% MVIC, UT: 1.3–28.0% MVIC, MT: 8.6–47.1% MVIC, LT: 3.8–47.3% MVIC). Significant differences occurred between the four arm positions for the UT and LT. The one-handed support revealed significant higher muscle activation than the double-handed support in every condition except for SA in Undercling arm position at 12° wall inclination. Increasing the wall inclination (from 0° to 12° overhang) led to a significant increase in muscle activation in nearly every exercise variation and muscle. These findings suggest that arm position, hand support and wall inclination are appropriate possibilities of altering muscle activation patterns in therapeutic climbing.  相似文献

Self-evaluation accuracy and satisfaction with performance: Are there affective costs or benefits of positive self-evaluation bias?     

Susanne Narciss  Hermann Koerndle 《International Journal of Educational Research》2011,50(4):230-240

This paper examines how self-evaluation biases may influence satisfaction with performance. A review of theoretical positions suggests there are two views, both of which are supported by studies involving laboratory tasks. The first view predicts affective costs, and the second affective benefits of positive self-evaluation bias. We test the opposing predictions with the data of a study in which fifth-graders’ self-evaluation, performance, and satisfaction with performance were measured before and after a four-week arithmetic training program. Our findings support the benefit view, that is, students with a negative self-evaluation bias rated their satisfaction with performance significantly less than those with positive bias, even though both performed comparably.  相似文献   

High School Biology Teachers’ Views on Teaching Evolution: Implications for Science Teacher Educators     

Ronald S. Hermann 《Journal of Science Teacher Education》2013,24(4):597-616

In the US, there may be few scientific concepts that students maintain preconceived ideas about as strongly and passionately as they do with regard to evolution. At the confluence of a multitude of social, religious, political, and scientific factors lies the biology teacher. This phenomenological study provides insight into the salient aspects of teaching evolution as viewed by public high school biology teachers. Transcribed interviews were coded, and data were sorted resulting in key themes regarding teachers’ views of evolution education. These themes are presented against the backdrop of extant literature on the teaching and learning of evolution. Suggestions for science teacher educators are presented such that we can modify teacher preparation programs to better prepare science teachers to meet the challenges of teaching evolution.  相似文献
