This document provides a review of acids and bases, including their characteristics, common examples, naming conventions, and reactions. It discusses how acids increase hydrogen ion concentration in solution while bases increase hydroxide ion concentration. Strong acids and bases are memorized. Metal oxides form bases in water while non-metal oxides form acids. Acids and bases neutralize through reactions that form water and a salt. Titrations involve using a solution of known concentration to determine the concentration of an analyte. [/SUMMARY]

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
Students, digital devices and success - Andreas Schleicher - 27 May 2024..pptxEduSkills OECD
Andreas Schleicher presents at the OECD webinar ‘Digital devices in schools: detrimental distraction or secret to success?’ on 27 May 2024. The presentation was based on findings from PISA 2022 results and the webinar helped launch the PISA in Focus ‘Managing screen time: How to protect and equip students against distraction’ https://www.oecd-ilibrary.org/education/managing-screen-time_7c225af4-en and the OECD Education Policy Perspective ‘Students, digital devices and success’ can be found here - https://oe.cd/il/5yV

2. LEARNING OBJECTIVES
• REVIEW THE BASIC CHARACTERISTICS OF ACIDS
AND BASES.
• PRACTICE HOW TO NAME ACIDS AND BASES.
• MEMORIZE STRONG ACIDS AND BASES.
• DETERMINE WHICH OXIDES WILL PRODUCE ACIDS
AND WHICH WILL PRODUCE BASES.
• REVIEW TITRATION VOCABULARY.
4. CHARACTERISTICS OF ACIDS AND BASES
ACIDS
• TASTE SOUR
• TURN BLUE LITMUS
PAPER RED
• HAVE A PH < 7.0
• ARE CORROSIVE
BASES
• TASTE BITTER
• TURN RED LITMUS
PAPER BLUE
• HAVE A PH > 7.0
• ARE CAUSTIC
5. ACIDS
• ARE MOLECULAR COMPOUNDS THAT FORM IONS
IN AQUEOUS SOLUTION.
• INCREASE [H+] IN SOLUTION.
• MEMORIZE 6 STRONG ACIDS:
10. NAMING BASES
BASES ARE IONIC HYDROXIDES AND SO ARE NAMED
WITH THE SAME RULES AS IONIC COMPOUNDS.
11. OXIDES
METAL OXIDES
• FORM BASES
• CaO + H2O Ca(OH)2
• Li2O + H2O 2LiOH
NON-METAL OXIDES
• FORM ACIDS
• CO2 + H2O H2CO3
• SO2 + H2O H2SO3
12. NEUTRALIZATIO
N
EXAMPLES:
HNO3 (aq) + Al(OH)3(s)
3HNO3 (aq) + Al(OH)3(s) → Al(NO3)3 (aq) + 3H2O
(l)
3H+ + 3NO3
-(aq) + Al(OH)3(s) → Al+3 +3NO3
- +
3H2O (l)
3H+(aq) + Al(OH)3(s) → Al+3(aq) + 3H2O (l)
ACIDS REACT
WITH BASES TO
FORM WATER
AND A SALT.
13. NEUTRALIZATIO
N
EXAMPLES:
Solid silver hydroxide and hydrobromic acid
ACIDS REACT
WITH BASES TO
FORM WATER
AND A SALT.
AgOH(s) + HBr(aq) → AgBr(s) + H2O (l)
AgOH(s) + H+(aq) +Br-(aq) → AgBr(s) +
H2O (l)
AgOH(s) + H+(aq) +Br-(aq) → AgBr(s) +
H2O (l)
14. TITRATIONS – VOLUMETRIC ANALYSIS
Buret - lab apparatus consisting of a graduated glass tube with a
spigot at one end used for titrations.
Titrant – solution of known concentration
Analyte – substance being analyzed
Equivalence point (Stoichiometric point) – The point in the titration
when exactly enough titrant has been added to react exactly with
the analyte.
Indicator – substance added to the analyte that changes color at
(or very near) the equivalence point.
Endpoint – The point where the indicator actually changes color.
(Ideally corresponds with equivalence point)
Phenolphthalein – indicator often used for acid/base titrations. It
15. TITRATIONS – VOLUMETRIC ANALYSIS
• Titrations can be done with acids and bases and with
redox reactions (more next week).
• Titrations are used to standardize (determine the
concentration) of a solution.
