A critical discourse analysis of sexuality education in the Australian curriculum

This article examines the sexuality education component of the national Australian Curriculum: Health and Physical Education (AC:HPE) with a focus on sexuality education discourses. A critical discourse analysis explored official AC:HPE documents in relation to sexuality education; the sexuality education discourses present within these documents; teacher roles and expectations associated with each discourse; and Australia’s broader social context in relation to education. Findings reveal that the AC:HPE emphasises a teacher-facilitated approach to sexuality education, which contrasts with teacher-centred work dominating the field prior to its release. This approach is in line with recent shifts in education towards strengths-based learning in which students are encouraged to think critically about issues. Despite these emphases, and while the AC:HPE is meant to be used flexibly as a guideline or framework, certain ambiguities within it may leave teachers’ roles open to interpretation and practices therefore unchanged or undisputed.     

The effects of first programming language on college students’ computing attitude and achievement: a comparison of graphical and textual languages

Background and Context: The relationship between novices’ first programming language and their future achievement has drawn increasing interest owing to recent efforts to expand K–12 computing education. This article contributes to this topic by analyzing data from a retrospective study of more than 10,000 undergraduates enrolled in introductory computer science courses at 118 U.S. institutions of higher education.

Objective: We explored the relationship between students’ first programming languages and both their final grades in an introductory computer science course and their attitudes about programming.

Method: Multiple matching techniques compared those whose first language was graphical (e.g., Scratch), textual (e.g., Java), or absent prior to college.

Findings: Having any prior programming experience had positive effects on both attitudes about programming and grades in introductory computer science courses. Importantly, students whose first language was graphical had higher grades than did students whose first language was textual, when the languages were introduced in or before early adolescent years.

Implications: Learning any computer language is better than learning none. If programming is to be taught to students before early adolescence, it is advised to start with a graphical language. Future work should investigate the transition between different types of programming languages.     

Information virus: Contaminated subject matter in instructional materials

Summary In industralized nations, information anxiety and information overload are topics of discussion. Books have been written about how to evaluate literature reviews where hundreds of items are being assessed.In many developing nations, information starvation is more the norm. The authors have begun exploring how information viruses can cause invalid content to work into an instructional design and permeate deeply into an educational system, ultimately producing good learning of subject matter that is out of date, contains serious omissions, or is inaccurate or misleading.There are ways to forestall information viruses from entering instructional materials. Much could be achieved by using new information search technologies and telecommunications links, fostering better appreciation of basic information technology, and upgrading the role of librarian in the instructional design process. Changes are needed in attitudes of government ministries and foreign aid funding agencies in order to support efforts to prevent information viruses from occurring.Dr. David Giltrow is an independent consultant specializing in the application of educational technology in developing countries.

The (Dis)inclusion of Latina/o Interests from Utah’s Dual Language Education Boom

Utah’s state planned model of dual language education has grown and spread rapidly. Drawing on critical race theory and LatCrit, we examined state policy documents and promotional materials for their discursive portrayal of Latinas/os. Our analysis revealed a pattern of centering the interests of the White, English-dominant majority and those without an ethnic connection to the target language, while marginalizing or silencing Latina/o interests. Implications for dual language education stakeholders are discussed.     

Attitudes toward science: measurement and psychometric properties of the Test of Science-Related Attitudes for its use in Spanish-speaking classrooms

Understanding attitudes toward science and measuring them remain two major challenges for science teaching. This article reviews the concept of attitudes toward science and their measurement. It subsequently analyzes the psychometric properties of the Test of Science-Related Attitudes (TOSRA), such as its construct validity, its discriminant and concurrent validity, and its reliability. The evidence presented suggests that TOSRA, in its Spanish-adapted version, has adequate construct validity regarding its theoretical referents, as well as good indexes of reliability. In addition, it determines the attitudes toward science of secondary school students in Santiago de Chile (n?=?664) and analyzes the sex variable as a differentiating factor in such attitudes. The analysis by sex revealed low-relevance gender difference. The results are contrasted with those obtained in English-speaking countries. This TOSRA sample showed good psychometric parameters for measuring and evaluating attitudes toward science, which can be used in classrooms of Spanish-speaking countries or with immigrant populations with limited English proficiency.     

Using Shiny to illustrate the probability density function concept

The transition from the probability mass function for discrete random variables to the probability density function for continuous random variables is not straightforward, especially to students from the health and social sciences. An R Shiny application was created to assist the learning process of probability density function.
