The Effects of a Flipped Classroom Model of Instruction on Students’ Performance and Attitudes Towards Chemistry

This study establishes the effects of a flipped classroom model of instruction on academic performance and attitudes of 66 first-year secondary school students towards chemistry. A pre-test and post-test experimental design was employed to assign students randomly into either the experimental or control group. In order to assess the suitability of using flipped model of instruction, students were divided in two groups. For the first group called the experimental group, a “flipped classroom” was used in which the students were given video lessons and reading materials, before the class to be revised at home. On the other hand, the second group followed traditional methodology, and it was used as control. The rate of reaction knowledge test and the chemistry attitude scale were administered. In addition, the researcher documented classroom observations, experiences, thoughts and insights regarding the intervention in a journal on a daily basis in order to enrich the data. Students were interviewed at the end of the research in order to enrich the qualitative data also. Findings from this study reveal that the flipped instruction model facilitates a shift in students’ conceptual understanding of the rate of chemical reaction significantly more than the control condition. Positive significant differences were found on all assessments with the flipped class students performing higher on average. Students in the flipped classroom model condition benefited by preparing for the lesson before the classes and had the opportunity to interact with peers and the teacher during the learning processes in the classroom. The findings support the notion that teachers should be trained or retrained on how to incorporate the flipped classroom model into their teaching and learning processes because it encourages students to be directly involved and active in the learning.     

The Influence of Risk Factors on Preschoolers’ Spanish Vocabulary Development in the Context of Spanish Instruction

Research Findings: This longitudinal study investigated the Spanish vocabulary development of dual-language-learning (DLL) children (N = 150) from Spanish-speaking, low-income, predominantly immigrant homes who were enrolled in a state-funded preschool program that provided instruction in Spanish. Children’s Spanish vocabulary trajectories were examined, as were patterns of co-occurring risk. In addition, the relation of individual and cumulative risk factors at preschool entry on Spanish vocabulary development was explored. Findings reveal that, on average, children’s receptive Spanish vocabulary skills, which started below age-level norms at the beginning of the preschool year, grew to surpass age-level norms by the end of the year. These gains were made despite children facing, on average, eight risk factors. The investigation of patterns of co-occurring risk and the effect of individual risk factors on Spanish vocabulary outcomes reveal that some social risk factors, such as having an unemployed parent, might function as a protective factor in this population. Practice or Policy: This study paves the way for future work in determining the role of native-language instruction for supporting language growth among DLL children. In addition, it expands the research literature on the nature and influence of social and economic risks in this population of children.     

Developing Low-Income Preschoolers’ Social Studies and Science Vocabulary Knowledge Through Content-Focused Shared Book Reading

Abstract

This study evaluated the effects of integrating science and social studies vocabulary instruction into shared book reading with low-income preschool children. Twenty-one preschool teachers and 148 children from their classrooms were randomly assigned at the class level to either the Words of Oral Reading and Language Development (WORLD) intervention or a practice-as-usual condition. Children were screened and selected to approximate three vocabulary levels (15th, 30th, and 50th). WORLD teachers implemented the intervention in small groups of 5 to 6 students, 5 days per week, 20 minutes per session, for 18 weeks. Findings from multilevel models indicated statistically and practically significant effects of the WORLD intervention on standardized measures of receptive vocabulary (δ_T = 0.93) and on researcher-developed measures of expressive (δ_T = 1.01) and receptive vocabulary (δ_T = 1.41). The WORLD intervention had an overall main effect, regardless of entry-level vocabulary, a finding that speaks to its potential applicability in preschool classrooms.

The Effects of Socio-scientific Instruction on Pre-Service Teachers’ Sense of Efficacy for Learning and Teaching Controversial Family Health Issues

This research investigates the effects of socioscientific instruction on pre-service teachers’ sense of efficacy in the teaching and learning of controversial family health issues. For this purpose, a total of 251 students from two teacher training colleges participated in the study and were randomly assigned as experimental and control groups. The experimental group was taught the contents of the controversial family health issues using socioscientific instruction approach and the control group was taught the same content using a more traditional approach. Quantitative data were obtained from both groups after responding to the ‘Teacher sense of Efficacy Scale’ as instrument used for data collection before and after the treatments. Analysis of covariance was used in data analysis of which the pre-treatment scores were used as covariates. Qualitative interviews were conducted with ten participants randomly selected from the experimental group before and after the treatment to deepen and elaborate the quantitative data. The quantitative and qualitative findings indicate that the integration of the socioscientific instruction have significantly affected the pre-service teachers’ sense of efficacy in favour of the experimental group that shows a more stronger sense of efficacy. It was concluded that the socioscientific instruction is significantly effective in changing the pre-service teachers’ weaker sense of efficacy to a stronger one in the controversial family health issues.

A Comparison of Multiple-Strategy Methods: Effects on Fourth-Grade Students’ General and Content-Specific Reading Comprehension and Vocabulary Development

Abstract

In this study, we compared the effects of two experimental multiple-strategy approaches (content-area comprehension and vocabulary) to typical fourth-grade social studies instructional practices. An 18-week, cluster-randomized study was conducted to estimate effects measured by normative-referenced reading comprehension and vocabulary measures and researcher- and district-developed measures of social studies vocabulary and content. Forty-eight teachers and their respective 903 students from 15 schools were randomly assigned by school to one of three conditions: content vocabulary, content reading comprehension, or typical practice. Experimental teachers participated in 6 professional development sessions over 21 weeks. Structural equation modeling results indicated reliable differences favoring both experimental conditions over typical practice on the social studies content measure and substantively important effects on content and standardized vocabulary measures. Students in the vocabulary intervention also outperformed typical practice peers on the curriculum-based vocabulary assessment. Effects of the comprehension and vocabulary conditions were comparable except for the significant effect of vocabulary on the curriculum-based vocabulary measure. Effect sizes for teaching quality on the standardized comprehension measure ranged from d = .26 to .32; however, these effects were not statistically significant.     

Effects of perceptions of the learning environment and approaches to learning on Chinese undergraduates’ learning

This study examined the relationship between students’ perceptions of the learning environment, high school performance, approaches to learning, and learning outcomes (generic skills development and course satisfaction). A sample of 74,687 undergraduates from 39 full-time regular universities in China responded to a questionnaire comprising four self-constructed scales. The results supported the reliability and validity of the instruments. A structural equation model showed that approaches to learning mediated the relationship between perceptions of the learning environment and learning outcomes. Specifically, deep approach was found to positively predict learning outcomes. Good teaching positively predicted deep and surface approaches, as well as learning outcomes. Student-faculty and peer interactions were strong predictors of learning approaches and learning outcomes. High school performance had weak effects on learning approaches and learning outcomes. These findings highlight the need of developing new instruments for assessing Chinese undergraduate students’ learning and have implications for improving undergraduate teaching in China.     

The Effects of Prior Knowledge and Audience on High School Students’ Writing

Abstract

To investigate the likelihood that explicit instruction in text summarization is being provided in classrooms, an "ideal lesson" method was used. Twelve experienced K-12 teachers were asked to devise summarization lessons appropriate to their learners and course content, to deliver the lessons, and to audiotape them. Lessons were transcribed, and instances of mentioning of summarization rules were coded. Only two teachers in the sample group discussed more than one of the five summarization rules assessed. The other teachers provided instruction that emphasized words and facts, despite their having been prompted to "assist students in improving text summaries." Staff development possibilities are discussed.

Comparing Two Methods of Writing Instruction: Effects on Kindergarten Students’ Reading Skills

ABSTRACT

This experimental study directly compared the effects of two prevalent forms of classroom writing instruction, interactive writing and writing workshop, on kindergarten students’ acquisition of early reading skills. Repeated measures data was collected at four points over 16 weeks to monitor growth of 151 kindergarten students in phonological awareness, alphabet knowledge, and word reading. Results of this study showed students in both the interactive writing group and the writing workshop group demonstrated significant growth over time for each of the three outcome measures, with no statistically significant difference between groups for any of the outcome measures at any of the time points. This study provides evidence that, when consistently implemented during the first 16 weeks of kindergarten, interactive writing and writing workshop are equally effective in promoting acquisition of early reading skills.     

The Effects of Prior-knowledge and Online Learning Approaches on Students’ Inquiry and Argumentation Abilities

This study investigated the effects of students’ prior science knowledge and online learning approaches (social and individual) on their learning with regard to three topics: science concepts, inquiry, and argumentation. Two science teachers and 118 students from 4 eighth-grade science classes were invited to participate in this research. Students in each class were divided into three groups according to their level of prior science knowledge; they then took either our social- or individual-based online science learning program. The results show that students in the social online argumentation group performed better in argumentation and online argumentation learning. Qualitative analysis indicated that the students’ social interactions benefited the co-construction of sound arguments and the accurate understanding of science concepts. In constructing arguments, students in the individual online argumentation group were limited to knowledge recall and self-reflection. High prior-knowledge students significantly outperformed low prior-knowledge students in all three aspects of science learning. However, the difference in inquiry and argumentation performance between low and high prior-knowledge students decreased with the progression of online learning topics.

The linear and nonlinear effects of organized extracurricular activities on Chinese Preschoolers’ development

How children spend time outside of school has consequences for their learning and development. Research on extracurricular participation has focused primarily on school-aged children and youth in Western societies. Yet, extracurricular activities are a common but understudied context of early development in Mainland China. In the present study, we employed the developmental model and the threshold model as a lens to examine the linear and nonlinear impact of extracurricular participation on three domains of development among 695 Chinese preschoolers. There are three main findings. First, there was partial support for the linear effect model (i.e., the developmental model). After controlling for demographic variables and children’s prior performance, extracurricular involvement was positively associated with children’s cognitive and language development, but not to social-emotional development. Second, there was also partial support for the overscheduling hypothesis (i.e., the threshold model). The results showed a quadratic effect of intensity, breadth, and total number of extracurricular activities on children’s social-emotional development, as well as a quadratic effect of the breadth of extracurricular participation on children’s language development. Finally, we extended the traditional overscheduling hypothesis by examining how duration of extracurricular involvement interacted with three other dimensions of involvement. The results suggest that increasing the number or intensity of extracurricular activities would benefit children’s language development when participation duration was relatively short. However, these influences became neutral at average levels of duration and harmful in cases of very long duration. Implications of our findings are discussed.     

The Impact of a Practice-Teaching Professional Development Model on Teachers’ Inquiry Instruction and Inquiry Efficacy Beliefs

This study examined changes in middle school teachers’ beliefs about inquiry, implementation of inquiry practices, and self-efficacy to teach science through inquiry after participating in a year-long professional development program. The professional development model design was based on Bandura’s (1986) social cognitive theory of learning and literature on effective professional development. Using the Electronic Quality of Inquiry Protocol (EQUIP) before and after the program (Marshall, Smart & Horton, 2010), teachers’ quality of inquiry instruction significantly increased across all 4 EQUIP factors. To assess teachers’ inquiry teaching efficacy, the Teaching Science as Inquiry (TSI; Dira-Smolleck, 2004) instrument was administered 3 times to the teacher participants. Changes between time points of TSI administration were examined for personal self-efficacy and outcome expectancy across 5 essential features of classroom inquiry. Findings for the personal self-efficacy scale showed statistically significant gains from pre-Institute to 1-year follow-up for all 5 inquiry features. Teachers’ outcome expectancy beliefs significantly increased across the program for 3 of the 5 essential features of inquiry. The results indicate the effectiveness of the professional development model at increasing the participants’ inquiry efficacy as well as the quality of their inquiry instruction. Our study provides evidence to support the need to include collaborative practice-teaching and reflection opportunities within professional development models that aim to increase teachers’ use of inquiry-based instructional strategies.
