Quality of instruction and achievement outcomes     

Franz E. Weinert  Friedrich-W. Schrader  Andreas Helmke 《International Journal of Educational Research》1989,13(8)

This chapter reviews the fundamental assumptions, main results, and major problems of research on instructional quality and cognitive student outcomes. Although considerable progress has been made in this field of research, the present theoretical state, encompassing mostly simple process-product relations, is far from satisfactory. Findings from our own research demonstrate that it is both necessary and fruitful to expand the simple process-product paradigm by including cumulative, interactive, compensatory, and contextual effects.  相似文献

Young people’s cognitive achievement as fostered by hands-on-centred environmental education     

Olivia Dieser  Franz X. Bogner 《Environmental Education Research》2016,22(7):943-957

In line with previous studies, where outdoor nature experience was shown to support adolescents’ environmental knowledge, our study monitored the influence of a hands-on environmental programme within a National Park on cognitive knowledge achievement. A sample of 4th and 5th graders (n = 289) completed a week-long outreach conservation programme with two follow-up options: the first group (n = 170) interacted with thematic posters, the second group (n = 128) also completed a thematic board game. In a quasi-experimental design, we analysed both versions with regard to achievement efforts and individual situational emotions. Altogether, programme participation added cognitive knowledge, while group one (poster and board game as follow-up option) outmatched group two (just the poster option). Measures of 'state' and 'situational' emotions regarding the programme and right after game participation revealed positive effects toward knowledge. Thus, we conclude, direct experiences with nature and additional hands-on follow-up activities may foster a student’s cognitive achievement in such programmes.  相似文献   

Three-Year Longitudinal Study: Impact of a Blended Learning Program—Lexia® Core5® Reading—on Reading Gains in Low-SES Kindergarteners     

Paul Macaruso  Shani Wilkes  Sarah Franzén  Rachel Schechter 《学校用计算机》2019,36(1):2-18

This three-year longitudinal study tracked the reading performance of 68 kindergarten students from low SES backgrounds. These students received instruction with a blended learning program ——Lexia® Core5® Reading—from the start of kindergarten through second grade. During each school year the students made significant gains on a standardized reading test. However, performance on the test declined significantly from the spring of one school year to the fall of the next, indicative of a substantial summer slide. Yet, further comparisons revealed that performance from the fall of one school year to the fall of the next showed significant improvement, pointing to the benefits of school-based instruction to help overcome the summer slide. More than 90% of low performers who started kindergarten scoring below average on the standardized test finished second grade scoring average or better. Benefits of Lexia Core5® Reading to support reading growth in elementary school students from low SES backgrounds are discussed.  相似文献

Investigations of Modellers and Model Viewers in an Out-of-School Gene Technology Laboratory     

Mierdel  Julia  Bogner  Franz X. 《Research in Science Education》2019,51(2):801-822

Genetics is known to be one of the most challenging subjects in biology education because of its abstract concepts and processes. Therefore, hands-on experiments in authentic learning environments are supposed to increase comprehensibility and provide otherwise unavailable experiences to students. We applied a hands-on module in an out-of-school gene technology lab, combining experimentation and model work, in order to support the experimental work. In comparing the impact of two different approaches on cognitive achievement, cognitive load and instructional efficiency, we divided our sample (N = 254) into two groups: While both were subjected to the experimental part of the module, the modellers (n = 120) were required to generate a DNA model using assorted handcrafting materials, whereas the model viewers (n = 134) worked with a commercially available school model of DNA structure. Interestingly, the model viewers performed significantly better regarding a mid-term knowledge increase, while individual cognitive load scores during the activity remained similar. Accordingly, the model viewing approach produced significantly higher scores for instructional efficiency, pointing to enhanced cognitive achievement through a more intense perception of the DNA models’ correct contents. While at the first glance our results seem surprising, implications for teaching when models come into play and ways to avoid such discrepancies are discussed. Consequently, recommendations for classroom impacts are presented.

The influence of situational emotions on the intention for sustainable consumer behaviour in a student-centred intervention     

Gabriele Fröhlich  Daniela Sellmann  Franz X. Bogner 《Environmental Education Research》2013,19(6):747-764

Within the curriculum guidelines for Bavaria, we designed a hands-on educational programme for teaching sustainability with regard to agriculture, food and consumerism, partly implemented on a farm as an out-of-school learning setting. The participants were fifth graders (N?=?176). The research followed a quasi-experimental design and used the subscale consumerism of the General Ecological Behaviour Scale and situational emotions (interest, well-being, boredom) to focus data collection activities. The study monitored the students’ knowledge increase and their Inclusion of Nature in Self (INS) scores as possible influencing factors on environmental behaviour. After participation in the programme, while we found that the students intended to consume in more environmentally friendlier ways, this intention did not persistent over a seven-week time span, nor did it relate to the INS or knowledge scores. There was, however, a high correlation with positive situational emotions like interest (r?=?.46, p???.001) and well-being (r?=?.39, p???.001), and a negative correlation with boredom (r?=??.42, p???.001). We conclude that the ‘effect’ of the programme immediately measured after the intervention was strongly linked to situational (short-term) emotions, and should be considered in educational planning as well as the evaluation of sustainability teaching and learning.  相似文献   

Promoting connectedness with nature through environmental education     

Anne K. Liefländer  Gabriele Fröhlich  Franz X. Bogner  P. Wesley Schultz 《Environmental Education Research》2013,19(3):370-384

It has been suggested that a positive human–nature relationship is essential for countering today’s environmental problems. Prior environmental education research has focused largely on knowledge or attitudinal outcomes, and few studies have examined the ability of environmental education programmes to promote connectedness with nature. Therefore, our goal was to (1) examine differences in connectedness with nature among a sample of children with differing ages and academic tracks, and (2) investigate whether environmental education can help promote and sustain connectedness with nature. With a pre-, post- and retention test design, we assessed a comprehensive four-day environmental education programme on water at a school field centre, using the inclusion of nature in self (INS) scale to identify the change in connectedness of 9–10-year-old pupils and 11–13-year-old pupils. We found that younger children and university-track pupils had higher INS scores than older children and general-education-track pupils, respectively. Participating in environmental education resulted in a robust short-term increase in connectedness with nature in both age groups. However, only the younger pupils’ connectedness remained sustained four weeks following the treatment. Environmental educators should keep in mind that strengthening connectedness to nature is more sustainable before the age of 11.  相似文献
