Elementary science textbooks: Their contents,text characteristics,and comprehensibility

The purpose of this article is to present findings from a systematic analysis of elementary-school science textbooks. Comparisons of content domains and vocabulary are presented for the Merrill (1982) and Silver-Burdett (1985) science programs, grades 1–5 as well as the fourth-grade Holt (1980) and fifth-grade McGraw-Hill (1974) texts. Analyses of how each publisher presents information, types of questions, and various text characteristics reveal striking differences between programs. Systematic comparisons of content domains between programs also reveal few instances of “inconsiderate” texts. The textbooks analyzed were selected because they are used in the three school districts participating in our longitudinal study. Results are discussed in light of the differences found between programs regarding textbook content and opportunity to learn, the greater amounts of text and activities within each program, and teachers' probable uses of textbooks, the long-term results of students' exposure to various textbooks, and the need for careful examination of materials in order to determine their quality.     

Study orchestration: the manifestation,interpretation and consequences of contextualised approaches to studying

This paper sets out the conceptual and empirical basis for the concept of study orchestration. The manifestation of study orchestration at a group, and at an individual level, is illustrated by means of an example that captures the range of individual differences, and of individual similarities, that typically occur. The interpretation and the categorisation of study orchestration is discussed and further illustrated by means of examples, as are the linkages between such categorisations and learning outcome. Disintegrated orchestrations, in particular, are discussed and interpreted in more detail by means of interview data. Important properties of individual study orchestration such as their stability and their contextual sensitivity are then addressed in terms of their contribution to intervention programmes for students who may be academically at risk. This paper concludes with a discussion of the concept of metaorchestration which is seen as a logical development of the concept of metalearning and which is viewed as having important consequences in terms of intervention programmes.     

The attitude towards nature,and incidence of sexual intimacy among students at a South African University

The authors, of the University of Stellenbosch, South Africa, surveyed 60 male university students of mean age 21.37 years and 79 female students of mean age 20.13 years with the goal of gaining insight into their sex behavior and their attitudes toward sexuality. The home language of 83% of the women and 85% of the men was Afrikaans, while the remaining subjects had English as a home language. One student was married, three were engaged to be married, and two lived together with a person of the opposite sex. 51 students were in steady relationships and 82 were single. 82% of the men and 90% of the women choose to have sex with someone of the same race. The study found a relatively low occurrence of sexual intercourse and promiscuity, and a very high percentage of subjects regarded themselves as heterosexual and as morally and religiously conservative. 97% of the men and 99% of the women regarded themselves as being heterosexual, and 3% of men and 1% of women regarded themselves as being bisexual. 6.6% of men and 1.34% of women, however, reported having had sexual contact with someone of the same sex. 37% of the men and 32% of the women reported having ever had sexual intercourse with a person of the opposite sex. These percentages are notably lower than those found by other investigators and the authors believe that a higher proportion of students at the university are actually sexually active than that suggested by this survey's findings. Among those sexually active, 17% of men and 18% of women were involved in sexual relationships with more than one partner. 68% of the sexually active men and women report using condoms often, 14% of men and 8% of women use contraceptives on an irregular basis, and 18% of men and 25% of women never use contraceptives. The birth control pill and condom were the most widely used methods. 85% of men and 86% of women felt that both partners should be responsible for taking precautions against unwanted pregnancy. These findings indicate that the overwhelming majority of subjects in this study are not at high risk for contracting AIDS.     

Effects of a Pre‐service Teacher Preparation Programme on Effective Instruction

A quasi‐experimental, treatment‐control group investigation was designed to test the effects of a pre‐service training course on effective instruction. Research findings from teacher effects research and cognitive strategy instruction were translated into two direct instructional models: one model for explicit or well‐structured skills and one model for implicit skills or higher‐level thinking strategies. Following a course on effective instruction from their teacher educators, student teachers implemented standardised lessons to apply selected research‐derived teaching behaviours and to increase pupil engagement rates. Based on trained observers’ pre‐and post‐training classroom observations, a significant treatment effect was found for student teachers’ teaching behaviours regarding effective instruction and for pupil engagement rates. Ratings from supervising teachers also showed that the student teachers who participated in the course on effective instruction used the recommended instructional skills after completion of the course significantly better than prior to the course.     

Threshold concepts and troublesome knowledge (2): Epistemological considerations and a conceptual framework for teaching and learning

The present study builds on earlier work by Meyer and Land (2003) which introduced the generative notion of threshold concepts within (and across) disciplines, in the sense of transforming the internal view of subject matter or part thereof. In this earlier work such concepts were further linked to forms of knowledge that are troublesome, after the work of Perkins (1999). It was argued that these twinned sets of ideas may define critical moments of irreversible conceptual transformation in the educational experiences of learners, and their teachers. The present study aims (a) to examine the extent to which such phenomena can be located within personal understandings of discipline-specific epistemological discourses, (b) to develop more extensively notions of liminality within learning that were raised in the first paper, and (c) to propose a conceptual framework within which teachers may advance their own reflective practice.     

Technology affordances: the 'real story' in research with K-12 and undergraduate learners

Computer technologies for learning environments have been introduced with great expectations for improved learning outcomes. However, the great improvements have not materialised; some of these extant studies are examined. Of all the explanations for these disappointing results, the least examined are the affordances of the computer tools. This paper provides a rationale for studying affordances and presents two studies in K‐12 and undergraduate settings showing how powerful affordances are in affecting outcomes. Finally, the paper presents guidelines on how to gradually move students from a game affordance of a computer to a learning mode.     

Science Teachers’ Misconceptions in Science and Engineering Distinctions: Reflections on Modern Research Examples

The aim of this exploratory study was to learn about the misconceptions that may arise for elementary and high school science teachers in their reflections on science and engineering practice. Using readings and videos of real science and engineering work, teachers’ reflections were used to uncover the underpinnings of their understandings. This knowledge ultimately provides information about supporting professional development (PD) for science teachers’ knowledge of engineering. Six science teachers (two elementary and four high school teachers) participated in the study as part of an online PD experience. Cunningham and Carlsen’s (Journal of Science Teacher Education 25:197–210, 2014) relative emphases of science and engineering practices were used to frame the design of PD activities and the analyses of teachers’ views. Analyses suggest misconceptions within the eight practices of science and engineering from the US Next Generation Science Standards in four areas. These are that: (1) the nature of the practices in both science and engineering research is determined by the long-term implications of the research regardless of the nature of the immediate work, (2) engineering and science are hierarchical, (3) creativity is inappropriate, and (4) research outcomes cannot be processes. We discuss the nature of these understandings among participants and the implications for engineering education PD for science teachers.     

Relationships between Hong Kong students’ perceptions of the learning environment and their learning patterns in post-secondary education

The present study aims to analyse the complex relationships between the relevant constructs of students’ demographic background, perceptions, learning patterns and (proxy measures of) learning outcomes in order to delineate the possible direct, indirect, or spurious effects among them. The analytical methodology is substantively framed against the studies of Richardson (British Journal of Educational Psychology 76:867–893, 2006, Higher Education 54:385–416, 2007) that utilised a regression-based methodology to infer the possible causal relationships among the relevant learning constructs. A composite research instrument, written in Chinese and derived from the Inventory of Learning Styles (ILS) and the Course Experience Questionnaire (CEQ), was used to collect students’ feedback on their perceptions of the learning environment and their learning patterns. Valid responses were obtained from 1,572 students studying at six institutions in the post-secondary education sector in Hong Kong, a new response-context for both the CEQ and the ILS. In adapting the research instruments to a new Chinese response-context, the findings are generally consistent with those reported in other published works (e.g. no relationship between students’ demographic background and their satisfaction with the programme, and a significant relationship between students’ exhibition of undirected learning patterns and low expected performance), but there are also some noteworthy discrepancies. The findings therefore buttress the confidence with which an ILS-based General Theoretical Model of student learning, adapted from Richardson (British Journal of Educational Psychology 76:867–893, 2006, Higher Education 54:385–416, 2007), may be used to conceptualise and interpret the dynamics of variation across different cultural response-contexts. While the CEQ provides some valuable complementary insights, it is an instrument that requires further development in the response-context of the present study.
